Abstract: Patent Title: TOT Based Smart Monitoring 
System for Preventive Maintenance of 
Electric Vehicles 
ABSTRACT 
Our invention "IOT based smart monitoring system for preventive 
maintenance of electric vehicles" is an automatic IoT based 
Monitoring System for Preventive Maintenance of Electric 
Vehicles consisting microprocessor / microcontroller based 
embedded monitoring unit contained in water and dust resistant 
and shock proof container for deployment in electric vehicle for 
condition monitoring of three vital units of electrical vehicle 
namely battery, BLDC motors and electronic / electrical circuits.  
The invented system is contained in box that can easily be 
deployed on the chassis of electrical vehicle. The invented system 
has four separate subunits to monitor, display the health status of 
electrical vehicle (EV) as per the condition of monitored units of 
electrical vehicle. The invented system has current sensor, voltage 
sensor and over / under charging sensor to monitor the status of 
battery bank. Invented system also has several sets of acoustic 
sensors, vibration sensor, temperature sensor, current sensor, 
voltage sensor deployed at suitable places near BLDC motors to 
monitor any malfunction or faulty condition. The invented system 
has set of current sensors which are deployed in series with 
electrical / electronic circuit. Voltage sensor deployed in parallel 
to critical components or electrical / electronic circuits of electrical 
vehicle and an overload sensor to monitor overload condition of 
electrical vehicle. The three major states monitored in electrical / 
electronic circuits are short circuit, open circuit and overload. The
sensor sends the signal to the electronic monitoring unit for 
processing. The electronic monitoring unit consist of a 
microprocessor/microcontroller with embedded program to 
monitor the operations of invented system. The invented system 
has four subunits for monitoring conditions of the electrical 
vehicle. The four subunits include EV battery monitoring 
subsystem, EV electronic / electrical circuit monitoring subsystem, 
EV BLDC motor condition monitoring subsystem and EV display 
on dashboard and user smartphone subsystem. The invented 
system has a power converter system which is connected to the 
battery of electrical vehicle and is used to convert voltage of 
electrical vehicle battery to the levels suitable for the invented 
system. The system consists of microcontroller / microprocessor 
with an embedded program to poll the sensors for obtaining 
monitoring data and analyze it. The system has electronic 
monitoring unit which is connected with an IoT gateway to 
transmit the EV monitoring data through wireless technology on 
the smartphone of the owner of electrical vehicle. The owner of the 
electrical vehicle can also plan or carryout preventive maintenance 
to avoid complete failure or breakdown of the electric vehicle.
