Study on Factors Affecting the Radiator-cooling of EV Power Battery Pack

: Based on the battery pack cooled by cooling package within electric vehicle, the cooling process of the power battery was studied by simulation and tests. The influence of the pump speed and fan level on the battery cooling was compared. The results of the simulation and tests showed that the final battery temperature of the high fan level was lower than 1°C relative to the low fan level, while the impact of the high speed water pump relative to the low speed water pump is within 1°C during idle cooling procedure.
