—— Overview Of Temperature Management System
Thermal management system TMS can ensure the safe operation of battery and improve the efficiency of battery utilization by reasonably managing the temperature of drive motor system, power battery and passenger compartment. There is a big difference between the thermal management system of new energy vehicle and traditional internal combustion engine vehicle. Air conditioning is often used to control the temperature of battery pack on new energy vehicle. Therefore, the Thermal management system not only needs to consider the heat dissipation of battery pack, power electronics, motor and so on, but also needs to consider the coupling effect with air conditioning and occupant compartment.
