Outline
In order to explore an effective test method for the thermal management performance of 48 V power battery, the thermal management performance of 48 V battery was studied and tested on a vehicle equipped with P0 mild hybrid system under different test conditions, ambient temperature and air conditioning mode. The results show that the World Light Vehicle Test Cycle (WLTC) is the most suitable to verify the thermal management performance of the 48 V battery. The high temperature performance of 48 V battery can be effectively verified by continuously performing 5 WLTC test cycles at a high temperature of 30~50 ℃, the low temperature performance of 48 V battery can be effectively verified by continuously performing 8 WLTC test cycles at low temperature of -25 ℃. The internal and external circulation mode of the air conditioner impacts the thermal balance temperature of the 48 V battery remarkably.
