THERMAL MANAGEMENT SYSTEM For Electric Vehicles

Recently some electric bikes caught fire due to failure of battery management system because of poor battery design. Unfortunately, proper thermal management is not there in most electric vehicles at present. So, here is a project to monitor the battery temperature and smoke detection to alert the EV user and stop the EV well in time to avoid further damage.

The authors' prototype of the thermal management system is shown in Fig. 1 and its block diagram is shown in Fig. 2.

Lithium-ion battery has a specified operational temperature of -20°C to +60°C. It will provide the longest service life if its temperature is always kept within approximately 10°C to 40°C.
