The use of green energy is becoming increasingly more important in today’s world. Therefore, electric vehicles are currently the best choice for the environment in terms of public and personal transportation. Because of its high energy and current density, lithium-ion batteries are widely used in electric vehicles. Unfortunately, lithium-ion batteries can be dangerous if they are not operated within their Safety Operation Area (SOA). Therefore, a battery management system (BMS) must be used in every lithium-ion battery, especially for those used in electric vehicles. In this project we develop an advanced battery thermal management system for emerging electric vehicles. In real time; The developed battery thermal management system is a combination of thermoelectric cooling, forced air cooling, and liquid cooling. The liquid coolant has indirect contact with the battery and acts as the medium to remove the heat generated from the battery during operation. Forced air assisted heat removal is performed from the condenser side of the thermoelectric liquid casing. A battery management system (BMS) is proposed which is used for electronic vehicle that manages a rechargeable battery, such as by protecting the battery from operating outside its safe operating area, monitoring its state using Arduino UNO microcontroller.   The controlling device of the whole system is ARDUINO UNO microcontroller. The integrated modules to the controller are temperature sensor, 3.7V lithium-ion Battery along with voltage sensor, cooling fan, buzzer and LCD Module. Microcontroller will display the voltage values as well as battery ambient temperature value on LCD displays. If the temperature value crosses the set limit, then microcontroller active the buzzer and turn on the cooling fan. To achieve this task microcontroller loaded program written in embedded C language.
