Computing device  104  may be implemented using a “shared nothing” architecture in which data is cached at the worker, in an embodiment, this may enable scalability of system  100  and/or computing device. 
     With continued reference to  FIG.  1   , computing device  104  may be designed and/or configured to perform any method, method step, or sequence of method steps in any embodiment described in this disclosure, in any order and with any degree of repetition. For instance, computing device  104  may be configured to perform a single step or sequence repeatedly until a desired or commanded outcome is achieved; repetition of a step or a sequence of steps may be performed iteratively and/or recursively using outputs of previous repetitions as inputs to subsequent repetitions, aggregating inputs and/or outputs of repetitions to produce an aggregate result, reduction or decrement of one or more variables such as global variables, and/or division of a larger processing task into a set of iteratively addressed smaller processing tasks. Computing device  104  may perform any step or sequence of steps as described in this disclosure in parallel, such as simultaneously and/or substantially simultaneously performing a step two or more times using two or more parallel threads, processor cores, or the like; division of tasks between parallel threads and/or processes may be performed according to any protocol suitable for division of tasks between iterations. Persons skilled in the art, upon reviewing the entirety of this disclosure, will be aware of various ways in which steps, sequences of steps, processing tasks, and/or data may be subdivided, shared, or otherwise dealt with using iteration, recursion, and/or parallel processing. 
     With continued reference to  FIG.  1   , system  100  may include a propulsor  108 . Propulsor  108  may include any propulsor described in this disclosure, including for example with reference to  FIG.  6   .

     With continued reference to  FIG.  1   , system  100  may include an electric motor  112 . As used in this disclosure, an “electric motor” is a device that converts electrical energy to mechanical work. Electric motor  112  may include any electric motor described in this disclosure, including for example with reference to  FIG.  6   . Electric motor  112  may be configured to power propulsor  108 . In some cases, electric motor  112  may power propulsor by way of a drivetrain. Drivetrain may include a rotating driveshaft. In some cases, drivetrain may be mechanically constrained using one or more bearing elements, such as without limitation needle bearings, roller bearings, and/or ball bearings. In some cases, drivetrain may include one or more universal joints, for example without limitation a Cardan joint, a double Cardan joint, a constant-velocity (CV) joint, a Rzeppa joint, a Tracta joint, a Birfield joint, a Weiss joint, a tripod joint, Thompson joint, Malpezzi joint and the like. 
     With continued reference to  FIG.  1   , system  100  may include a battery pack  116 . As used in this disclosure, a “battery pack” is an energy storage devices that includes a plurality of battery cells. As used in this disclosure, a “battery cell” is an electrochemical energy storage device. In some cases, battery pack  116  may be configured to provide electrical energy to electric motor  112 . Battery pack  116  may include a plurality of battery cells  120   a - d . For instance, in some cases, battery pack  116  may include one or more battery modules which include a battery cells  120   a - d . Battery pack may include any battery pack described in this disclosure, including for example with reference to  FIGS.  2 - 4   . 
     With continued reference to  FIG.  1   , system  100  may include at least a conductor  124 . As used in this disclosure, a “conductor” is any device that conducts thermal or electrical energy. Conductor  124  may provide electrical communication between one or more electrical components. As used in this disclosure, “electrical communication” is a capability to transfer electricity, for example from a battery pack to an electric motor. Conductor  124  may be composed of any electrically conductive material for example metals, such as steel, aluminum, copper, silver, gold, and the like. In some cases, conductor  124  may include a component of aircraft, for example without limitation a support structure, a chassis, or fuselage. In some cases, conductor  124  may include or be a part of an electric circuit. Conductor  124  may include wire, cables, busses, structure, printed circuits, and the like. In some cases, conductor  124  may be located within battery pack  116 , for example conductor  124  may include without limitation a conductive bus between two or more battery cells  120   a - d  within battery pack  116 . Alternatively or additionally, conductor  124  may be located outside of battery pack  116 , for example conductor  124  may include a wire or cable running from battery pack to an electrical component powered by the battery pack  116 , for example without limitation motor  112 . 
     With continued reference to  FIG.  1   , system  100  may include at least a contactor  128 . As used in this disclosure, a “contactor” is an electrical component configured to selectably disengage electrical communication. In some cases, a contactor may include a switch, a relay, a solenoid, a motor, or the like. At least a contactor may selectably disengage electrical communication within at least a conductor  124 . In some cases, a contactor may physically break a connection within a conductor to disengage electrical communication. In some embodiments, a contactor may include an electrically-controlled switch used for switching an electrical power circuit. In some cases, a contactor may be controlled by a circuit having a much lower power level than a switched circuit which the contactor selectably disengages. For instance, a contactor  128  comprising 24-volt coil electromagnet solenoid may switch a 230-volt motor circuit. Alternatively or additionally, in some cases, contactor  128  may be controlled in a non-electrical manner, such as without limitation pneumatically, hydraulically, mechanically, and the like. For example, without limitation in some cases, contactor  128  may be driven by compressed air. In some cases, a contactor  128  may be directly connected to high-current devices. For example, in some cases, a contactor  128  may switch more than 5 amperes or be used in electrical circuits having an electrical load greater than a kilowatt. In some cases, contactor  128  may be normally open. As used in this disclosure, “normally open” refers to a default or uncontrolled state being open, unconnected, or disengaged. In some cases, contactor  128  may be normally closed. As used in this disclosure, “normally closed” refers to a default or uncontrolled state being closed, connected, or engaged. In some embodiments, contactor  128  may be configured to control and/or suppress an arc produced when engaging, disengaging, or interrupting heavy motor currents. 
     With continued reference to  FIG.  1   , contactor  128  may be configured to include contact protection. Without adequate contact protection electrical arcing during use of contactor  128  may cause significant degradation of contacts. In some cases, an electrical arc may occur between two contact points (i.e., electrodes) when contactor  128  transitions from a closed-state to an open-state (break arc) or from an open-state to a closed-state (make arc). Break arc may be substantially more energetic and more destructive than make arc. Heat produced from electrical arc may cause damage to contacts within contactor  128 . For example, in some circumstances, heat may cause metal on contact to migrate with electrical current. In some circumstances. high temperature of arc (e.g., no less than 1,0000 Celsius) may disassociate surrounding gas molecules creating, for example ozone, carbon monoxide, and other compounds. In some cases, arc energy may slowly destroy contact, which may, in turn, cause some material to contaminant surroundings as fine particulate matter or conductive dust. In some cases, a contactor  128  may have a life span of 1,000 to 10,00,000 operations. In some cases, contactor  128  may include an air break contactor. An air break contactor operates in air and air (at atmospheric pressure) surrounds contacts and extinguishes a break arc when interrupting the circuit. Alternatively or additionally, contactor  128  may include a vacuum contactors, wherein a vacuum surrounds contacts and thereby substantially prevents an arc from forming ionized gas (i.e., plasma). Alternatively or additionally, contactor  128  may include an inert gas contactor, wherein an inert gas surrounds contacts. Inert gas requires a higher energy density to ionize and form plasma. In some cases, a fluid flow (e.g., a jet of compressed gas) may be used to direct an arc, for example away from contacts within contactor  128 . 
     With continued reference to  FIG.  1   , system  100  may include at least a gas sensor  132 . As used in this disclosure, a “gas sensor” is a device configured to detect a gas parameter as a function of at least a phenomena associated with a gas. Exemplary non-limiting gas sensors include flow sensors, pressure sensors, gas concentration sensors, and the like. In some cases, gas sensor  132  may be configured to detect at least a gas parameter associated with battery pack  116 . As used in this disclosure, a “gas parameter” is information representing at least a phenomenon associated with a gas. Gas sensor  132  may include any sensor described in this disclosure for detecting phenomenon associated with gas, including for example those described with reference to  FIG.  5   . Gas parameter may include any information associated with a detectable phenomenon associated with gas, including for example those described with reference to  FIG.  5   . In some embodiments, gas sensor  132  may include a volatile organic compound (VOC) sensor. A VOC sensor  132  may detect a VOC parameter. Exemplary non-limiting VOC parameters include concentration of at least a VOC. Exemplary non-limiting VOCs include reducing gases and oxidizing gases. Exemplary non-limiting reducing gases include alcohols, aldehydes, ketones, organic acids, amines, organic chloramines, aliphatic and aromatic hydrocarbons. Exemplary non-limiting oxidizing gases include sulfuric acid, nitric acid and ozone. In some cases, a VOC sensor may detect substantially one or a few preselected VOCs. Alternatively or additionally, a VOC sensor may detect substantially all or most VOCs, as in the case of a total VOC (TVOC) sensor. VOC sensor  132  may include a photoionization detector. In some cases, a photoionization detector  132  may measure VOCs and/o other gases in concentrations in ranges from parts per billion (ppb) to parts per million (ppm). In some cases, a photoionization detector may produce instantaneous readings and operate continuously. In some cases, a photoionization detector operates when high-energy photons (e.g., ultraviolet (UV) range) break molecules into ions. For example, in some cases, as gas compounds enter photoionization detector  132  they are irradiated by high-energy UV photons and ionized. Ionization can result in ejection of electrons and formation of charged ions. Ions may then produce electric current, which is detected by photoionization detector  132  as current signal representing a gas parameter. Greater concentrations of detected component within gas results in more ions produced, and greater detected current. In some cases current signal may be amplified and displayed on an ammeter or digital concentration display. Additionally, current signal may be processed according to any signal processing methods described in this disclosure. In some cases, different photon energies (e.g., wavelengths) of light are used to ionize different compounds. Exemplary non-limiting photon energies include 11.7 eV, 10.6 eV, 10.2 eV, 10.0 eV, 9.6 eV, and 8.4 eV. In some cases, photoionization detector  132  may only respond to components that have ionization energies similar to or lower than photon energy produced by a photoionization detector light source. In some cases, a photoionization detector may include a broad band light source and as a result not selectively measure different compounds, as these may ionize everything with an ionization energy less than or equal to the lamp photon energy. In some cases, common light source may have photons energy upper limits of approximately 8.4 eV, 10.0 eV, 10.6 eV, and 11.7 eV. Major and minor components of clean air all have ionization energies above 12.0 eV and thus do not interfere significantly in measurement of VOCs, which may have ionization energies below 12.0 eV. In some cases, gas sensor  132  may include a device to collect gas, such as without limitation a sorbent tube and/or a 2,4-Dinitrophenylhydrazine (DNPH) cartridge. Sorbent tubes may include a solid absorbent material, for example activated charcoal, silica gel, and organic porous polymers. In some cases, a solid sorbent may be selected to absorb a preselected molecule. In some cases, gas sensor  132  may include a gas concentration sensor and/or any gas chromatography device. An exemplary gas concentration sensor is an optical gas concentration sensor. 
     With continued reference to  FIG.  1   , non-limiting optical gas concentration sensors  132  include infrared transmission and/or absorbance spectroscopy type sensors and fluorescence excitation type sensors. Commonly, an optical gas concentration sensor  132  may include a radiation source and a radiation detector. In some versions, radiation source may include a light source that may generate a light and illuminate at least a portion of a gas. Radiation source may generate any of a non-limiting list of lights, including coherent light, non-coherent light, narrowband light, broadband light, pulsed light, continuous wave light, pseudo continuous wave light, ultraviolet light, visible light, and infrared light. In some cases, radiation source may include an electromagnetic radiation source that may generate an electromagnetic radiation and irradiate at least a portion of a gas. Radiation source may generate any of a non-limiting list of radiations including radio waves, microwaves, infrared radiation, optical radiation, ultraviolet radiation, X-rays, gamma-rays, and light. Non-limiting examples of radiation sources include lasers, light emitting diodes (LEDs), light emitting capacitors (LECs), flash lamps, antennas, and the like. In some cases, radiation detector may be configured to detect light and/or radiation that has interacted directly or indirectly with at least a portion of a gas. Non-limiting examples of radiation detectors include photodiodes, photodetectors, thermopiles, pyrolytic detectors, antennas, and the like. In some cases, a radiation amount detected by radiation detector may be indicative of a concentration of a particular component in at least a portion of a gas. For example, in some exemplary embodiments, radiation source may include an infrared light source operating at a wavelength about 4.6 μm and radiation detector may include a photodiode sensitive over a range encompassing 4.6 μm. An exemplary infrared light source may include an LED comprising InAsSb/InAsSbP heterostructures, for example LED46 from Independent Business Scientific Group (IBSG) of Saint Petersburg, Russia. An exemplary infrared detector may include a mercury cadmium telluride photodiode, for example UM-I-6 HgCdTe from Boston Electronics of Brookline, Mass. In some cases, an amount of radiation at least a specific wavelength absorbed, scatter, attenuated, and/or transmitted may be indicative of a concentration of a component of gas. 
     With continued reference to  FIG.  1   , in some cases, gas concentration sensor  132  may include an infrared point sensor. An infrared (IR) point sensor may use radiation passing through a known volume of gas. In some cases, detector may be configured to detect radiation after passing through gas at a specific spectrum. As energy from infrared may be absorbed at certain wavelengths, depending on properties of gas. For example, carbon monoxide absorbs wavelengths of about 4.2-4.5 μm. In some cases, detected radiation within a wavelength range (e.g., absorption range) may be compared to a wavelength outside of the wavelength range. A difference in detected radiation between these two wavelength ranges may be found to be proportional to a concentration of a component of gas present. In some embodiments, an infrared image sensor may be used for active and/or passive imaging. For active sensing, radiation source may include a coherent light source (e.g., laser) which may be scanned across a field of view of a scene and radiation detector may be configured to detect backscattered light at an absorption wavelength of a specific target gas. In some cases, radiation detector may include an image sensor, for example a two-dimensional array of radiation sensitive devices, for example arranged as pixels. Passive IR imaging sensors may measure spectral changes at each pixel in an image and look for specific spectral signatures that indicate presence and/or concentration of target gases. In some embodiments, gas associated with battery pack  116  may result or be discharged from within at least a battery cell  120   a - d . For instance, in some cases, electrolyte may form a gas upon heating and prior to thermal runaway. In some cases, gas discharged from at least a battery cell  120   a - d  may include certain compounds indicate the gas&#39;s origin, such as without limitation VOCs. As used in this disclosure, “thermal runaway” is a failure mode for a battery characterized by high temperature. 
     With continued reference to  FIG.  1   , a computing device  104  may be configured to receive at least a gas parameter from at least a gas sensor  132 . Computing device  104  may be in communication with gas sensor or any other sensor described in this disclosure, for instance by way of one or more of a network, a circuit, a port, and the like. In some cases, gas parameter may be communicated by way of at least a signal from gas sensor  132  to computing device  104 . Computing device  104  may determine a battery condition associated with battery pack  116 . In some cases, computing device  104  may determine battery condition as a function of gas parameter. As used in this disclosure, a “battery condition” is information associated with a battery pack and/or a state of health or dysfunction thereof. Computing device may control at least a contactor  128  as a function of one or more of battery condition and gas parameter. For example, in some cases, computing device  104  may control at least a contactor  128  to selectably disengage electrical communication within at least a conductor  124  as a function of one or more of battery condition and gas parameter. 
     With continued reference to  FIG.  1   , In some cases, gas parameter may be used by computing device  104  to determine battery condition. For example, in some cases, gas parameter may include concentration of VOCs, such as VOCs originating from electrolyte. In this case, battery condition may be determined by comparing detected VOC concentration with at least a VOC concentration threshold. For instance in cases, where a detected VOC concentration value is found to be above VOC concentration threshold, battery condition may be determined to be at risk of thermal runaway. Alternatively or additionally, in some cases, gas parameter may include a gas flow or pressure reading. As a battery cell  120   a - d  heats, discharge gas may be formed. Either discharge gas is vented, in which case, gas flow may be measured, or discharge gas is constrained and gas pressure may be measured or inferred from measured strain of a battery cell structure. Likewise, measured gas pressure and/or flow values may be compared with predetermined thresholds to determine battery condition. In some cases, battery condition may be determined by using at least a machine-learning process. Machine-learning process may include any machine-learning model, algorithm, or process described in this disclosure, for example with reference to  FIG.  8   . 
     Still referring to  FIG.  1   , in some embodiments, at least a gas sensor  132  may be further configured to detect a first gas parameter associated with a first battery cell  120   a  of plurality of battery cells  120   a - d ; and contactor  128  may be further configured to selectably disengage electrical communication between the first battery cell  120   a  and battery pack  116 . Alternatively or additionally, in some embodiments, at least a contactor  128  may be further configured to disengage electrical communication between battery pack  216  and electric motor  112 . 
     Still referring to  FIG.  1   , in some embodiments, system  100  may additionally include at least a temperature sensor  136 . As used in this disclosure, a “temperature sensor” is a device configured to detect a temperature parameter as a function of at least a thermal phenomena. Exemplary non-limiting temperatures sensors include pyrometers, thermistors, thermocouples, infrared thermal sensors, thermal imaging cameras, and the like. Temperature sensor  136  may be configured to detect a temperature parameter associated with battery pack  116 .

Computing device  104  may be configured to receive at least a temperature parameter from at least a temperature sensor  136 . Computing device  104  may be in communication with temperature sensor, for instance by way of one or more of a network, a circuit, a port, and the like. In some cases, temperature parameter may be communicated by way of at least a signal from temperate sensor  136  to computing device  104 . In some embodiments, computing device  104  may determine a battery condition associated with battery pack  116  as a function of temperature parameter. 
     Still referring to  FIG.  1   , in some embodiments, system  100  may include at least another sensor  140 . Another sensor  140  may include any other (non-gas and non-temperature) sensor described in this disclosure, for example sensors described with reference to  FIG.  5   . Briefly, other sensor  140  may include electrical sensors. As described in this disclosure, an “electrical sensor” is a device that is configured to detect an electrical parameter associated with an electrical phenomena. Exemplary non-limiting electrical sensors include volt-meters, amp-meters, ohm-meters, multi-meters, oscilloscopes, and the like. In some cases, other sensor  140  may include a mechanical sensor. As used in this disclosure, a “mechanical sensor” is a device that is configured to detect a mechanical parameter associated with a mechanical phenomena. Exemplary non-limiting mechanical sensors include load cells, strain gauges, motion sensors (e.g., inertial measurement units, accelerometers, gyroscopes, etc.) vibrometers, and the like. In some cases, other sensor  140  may include an optical sensor. As described in this disclosure, an “optical sensor” is a device that is configured to detect an optical phenomena. Exemplary non-limiting optical sensors include photodetectors, photodiodes, pyrometers, cameras, image sensors (e.g., CMOS and CCD), and the like. 
     Still referring to  FIG.  1   , in some embodiments, computing device  104  may use multiple parameters in determining battery condition. For example, computing device  104  may use one or more of gas parameter, temperature parameter, electrical parameter, mechanical parameter, optical parameter, and the like. In some cases, computing device  104  may determine battery condition according to an algorithm which takes as input multiple parameters. In some cases, algorithm may compare at least a parameter with at least a threshold or threshold range, in order to determine battery condition. In some cases, algorithm may be predetermined by a programmer. Alternatively or additionally, in some cases, algorithm may be a machine-learning process such as a machine-learning model. For example, in some cases, a machine-learning model may be generated by training a machine-learning algorithm with training data. Exemplary training data may associate historical or representational parameters (e.g., gas concentrations, temperatures, and the like) with a known probability for thermal runaway and/or other catastrophic failure. In some cases, known probability may be indicated through a historic time until thermal runaway that has been found through destructive testing of at least a battery cell  120   a - d    
     Referring now to  FIG.  2   , an exemplary system  200  for battery management in an aircraft is illustrated by way of a block diagram.

     Still referring to  FIG.  8   , machine-learning module  800  may be configured to perform a lazy-learning process  820  and/or protocol, which may alternatively be referred to as a “lazy loading” or “call-when-needed” process and/or protocol, may be a process whereby machine learning is conducted upon receipt of an input to be converted to an output, by combining the input and training set to derive the algorithm to be used to produce the output on demand. For instance, an initial set of simulations may be performed to cover an initial heuristic and/or “first guess” at an output and/or relationship. As a non-limiting example, an initial heuristic may include a ranking of associations between inputs and elements of training data  804 .

A “machine-learning model,” as used in this disclosure, is a mathematical and/or algorithmic representation of a relationship between inputs and outputs, as generated using any machine-learning process including without limitation any process as described above, and stored in memory; an input is submitted to a machine-learning model  824  once created, which generates an output based on the relationship that was derived. For instance, and without limitation, a linear regression model, generated using a linear regression algorithm, may compute a linear combination of input data using coefficients derived during machine-learning processes to calculate an output datum. As a further non-limiting example, a machine-learning model  824  may be generated by creating an artificial neural network, such as a convolutional neural network comprising an input layer of nodes, one or more intermediate layers, and an output layer of nodes. Connections between nodes may be created via the process of “training” the network, in which elements from a training data  804  set are applied to the input nodes, a suitable training algorithm (such as Levenberg-Marquardt, conjugate gradient, simulated annealing, or other algorithms) is then used to adjust the connections and weights between nodes in adjacent layers of the neural network to produce the desired values at the output nodes. This process is sometimes referred to as deep learning.

For instance, a supervised learning algorithm may include flight elements and/or pilot signals as described above as inputs, autonomous functions as outputs, and a scoring function representing a desired form of relationship to be detected between inputs and outputs; scoring function may, for instance, seek to maximize the probability that a given input and/or combination of elements inputs is associated with a given output to minimize the probability that a given input is not associated with a given output. Scoring function may be expressed as a risk function representing an “expected loss” of an algorithm relating inputs to outputs, where loss is computed as an error function representing a degree to which a prediction generated by the relation is incorrect when compared to a given input-output pair provided in training data  804 .

Linear regression models may include least absolute shrinkage and selection operator (LASSO) models, in which ridge regression is combined with multiplying the least-squares term by a factor of 1 divided by double the number of samples. Linear regression models may include a multi-task lasso model wherein the norm applied in the least-squares term of the lasso model is the Frobenius norm amounting to the square root of the sum of squares of all terms. Linear regression models may include the elastic net model, a multi-task elastic net model, a least angle regression model, a LARS lasso model, an orthogonal matching pursuit model, a Bayesian regression model, a logistic regression model, a stochastic gradient descent model, a perceptron model, a passive aggressive algorithm, a robustness regression model, a Huber regression model, or any other suitable model that may occur to persons skilled in the art upon reviewing the entirety of this disclosure. Linear regression models may be generalized in an embodiment to polynomial regression models, whereby a polynomial equation (e.g. a quadratic, cubic or higher-order equation) providing a best predicted output/actual output fit is sought; similar methods to those described above may be applied to minimize error functions, as will be apparent to persons skilled in the art upon reviewing the entirety of this disclosure.
