Thermal Management

Thermal management consists of the management of heat dissipation of the motor, motor controller and lithium-ion batteries with different methods. Motor cooling is planned to be done by the existing radiator fan which turns on and off with set temperature. Motor controller cooling, on the other hand, is done through heat sink and also direct airflow while the car is moving.

Battery thermal management is considered the most critical aspect of all thermal issues in an EV. Our concept is to use forced air cooling where the flow of air is guided into the battery compartment and forced out by a series of blowers or fans. Temperature distribution around the batteries is being studied and additional cooling method can be considered accordingly.
