PFX2000
Supporting highly flexible battery evaluations for various test
configurations from small-size desktop systems to large-scale
systems with up to 240 channels
The PFX2000 Series offers a battery test system developed on
the basis of the experience and know- how that we haveamassed through implementing numerous custom-built battery
evaluation systems. This product adopts a unit structure thathouses charging/discharging power supply units (PFX2011 or
PFX2021) in a single unit frame (PFX2332). This enables you
to build your battery test environment in varying scale, from asmall-size system with a single cell to a large-scale system
consisting of up to 120 units (max. 240 channels when all theunits used are PFX2011), thus making it possible to support
virtually any number of channels necessary for the intended
te st . W hat ’s m o r e, t h e PF X2000 S e r i e s p r ov i d e s hi g havailability by allowing you to replace only those units that needmaintenance and to continue the test without shutting down theentire system (hot plug feature). Each channel is completely
independent of one another and thus can be controlled under
different test and timing conditions. In addition, the system
supports a rich set of protection features (OVP, UVP, OHP, etc.)
to prevent the test material from being destroyed by a system
malfunction or operation mistake.

Completely independent
2 c h a n n e l s (5 V/5 A , 25 W )PFX2021 (200-W unit) has a discharging mode that supports
20-value CC pulse and 20-value CP pulse discharging. It
employs a V/F converter to measure current during pulse
discharge, enabling quick measurement of the varying current
and highly accurate capacity evaluation. This makes PFX2021
suitable for use in charging/discharging simulations for suchdevices as PCs and digital cameras. Furthermore, PFX2021
features a power regeneration function that allows the energy
lost internally during discharge to be reused as the operation(charging) power, making this product more sophisticated as acharging/discharging power supply.
The application software (BPChecker2000), which is used tocontrol the PFX2000 Series system, is capable of controlling up
to six Espec Corp.’s thermostatic chambers for synchronized
testing. Using this software in combination of the optional
impedance measurement unit (PFX2211) can automate thetemperature characteristic testing process including impedance
measurement.

PFX2011 5V-5A 25W 2CH● Completely independent channels

The two channels of the unit are completely independent of one another and thus can be controlled
under different test conditions.

● 8-value CC pulse mode

Constant current pulse discharging mode for reproducing GSM and PDC burst patterns● High and low current ranges

You can toggle between two current ranges - high range with 0.1-mA resolution and low range with
0.01-mA resolution. In the low range, reproducibility and accuracy can be implemented with 1-mA
resolution, thus making product suitable for standby-mode current simulations for mobile devices.

● Pulse charging

PWM pulses are possible.

Ideal for characteristic evaluations for notebook PCs, digital cameras, etc.

PFX2021 20V-10A 200W

Features
Pulse Charging/Discharging Function

Temperature Measurement Function

A pulse charging mode is supported to assist
you in R&D efforts on sophisticated charger
simulations and charging methods.
Also, PFX2021 has a 20-value CP and CC pulse
discharging function. These features enable youto perform discharging simulations for packaged
bat teries used in notebook PCs and digital
cameras.

The system features a simple temperature
measurement function that uses a thermister(which comes with PFX2332) as a thermometer,
making it possible to measure temperature ona channel-by-channel basis. Also, in addition toallowing over temperature protection (OTP) to be
set as a protection function, the system permits
you to specify dT/dt (temperature rise per unittime) and MaxTemp (maximum temperature) as
the charging termination conditions.

Diverse Charging/Discharging
Termination Conditions
A number of conditions, such as voltage, time,
and temperature, can be specified as the charging and discharging termination conditions.

Highly Accurate Measurement Capability
A 24-bit A/D converter is adopted for measuring
voltage and current values, thus enabling highly
accurate measurement. Also, a built- in,temperature-controlled reference voltage circuit
ensures highly stable operation. A 16-bit D/Aconverter and a high-speed A/D converter are
fully utilized for pulse charging and discharging,
thereby making it possible to generate complex
current waveforms, measure the voltage at any
given point, and evaluate the pulse current. In
addition, a V/F converter specifically designed
for average current measurement is employed toprovide faithful measurement of average pulse
currents (PFX2021 only). The transient state of
the pulse current can also be measured exactly.
Error in current measurement resulting from theunbalance between the first and last transitions
is minimized.

Enhanced System Reliability
Various protection functions including overvoltage (overcharge) protection (OVP), undervoltage(overdischarge) protection (UVP), and overheat
protection (OHP), as well as a watchdog timer(system monitoring), are provided to enhance
the system reliability. In par ticular, the OVP
and UVP functions support a dual protection
mechanism offering software-based and hardware - based protec tions. Fur ther more, thesystem uses a MOS FET to switch states in the
charge/discharge/dwell cycle, making it reliable
enough to endure long consecutive operation.

Power Regeneration Function
If a preset amount of energy is lost internallyduring a discharge test, the power regeneration
function reuses the lost energy as the operation
power. This function contributes to making thesystem smaller, achieving power savings, andreducing waste heat. (For PFX2021 only)

Battery Voltage Detection Terminal withHigh Input ResistanceThe battery voltage detection terminal has highinput resistance (10 GΩ). Since there is very little
leak current, it is almost unlikely that the battery
will dry out during a test dwell.

Two Independent Channels Built in One Unit
The two channels are completely independent of
one another, and a different set of test conditions
can be set for each of them. (For PFX2011 only)

Hot Plug Feature
When in standby mode, any charging/discharging power supply unit can be replaced without
turning off the power of the unit frame.

Frames Interconnected via a TP-BUS
The 5-unit frames are interconnected to one
another and connected to the control unit via a
TP-BUS. To disconnect a unit frame from the
TP-BUS does not require turning off the powerof any other frame connected.

Control Unit Supporting Multiple Channels
The control unit PFX2121 can control a large
number of channels, supporting up to 120 channels
per unit (when all the controlled power supply
units are PFX2011). Also, it has a USB por t
for connection with a PC. You do not need toprepare a separate interface board if the PC you
want to connect supports the USB interface. Twocontrol units can be connected to a single PC.

SD002 BPChecker2000
BPChecker2000 is an application software package specificallydesigned for the PFX2000 Series system.

● Program Structure

BPChecker2000 enables you to set conditions for battery
charging/discharging characteristic tests, run the tests, andanalyzes test results using a PC. Capable of controlling two
120-channel control units (PFX2121) via the PC’s USB ports,
BPChecker2000 can exert control over up to 240 charging/discharging power supply channels. By adding an impedance
measurement unit (PFX2211), you can measure impedance ofup to 120 charging/discharging power supply channels that areconnected to the same control unit. Furthermore, if your PC
supports the GPIB communication environment, you can have
Espec Corp.’s thermostatic chambers externally controlled sothat tests can be conducted in synchronization with thetemperature inside the chambers.

BPChecker2000 consists of the five programs described below.

Test Condition Editor

Test Executive

This program lets you create and edit all conditions related tocharging/discharging testing. A total of 15 sheets of test condition
data can be created, with each sheet specifying both charging anddischarging conditions. It is also possible to set the number of times(repeats) that an individual sheet is to be repeated to form aparticular charging/discharging cycle, as well as the number oftimes (loops) that the entire set of sheets is to be repeated.

This program executes charging/discharging tests according to
the test condition filec r e a t e d w i t h Te s t
