Thermal Analysis on Power Battery of Intermittent Discharging under Sample Function

Abstract

For intermittent charging and discharging of vehicle power battery in the process of complex road, this paper puts forward a model of heat generation and heat transfer using sample function, and carried out some simulation of temperature distribution and difference of simple battery and when with cooling water plate. Results from the simulation show that temperature distribution and heat transfer in the discharging process has a good relationship with the actual process when using sample function to simulate both the simple battery and with cold water plate. It can look forward to that using sample function to simulate its thermal process has good reference for complex road.
