Heat Release and Indirect Liquid Cooling of Tractive Lithium Ion Battery

Abstract:

The tractive lithium ion batteries were gradually become the main energy provider for the Electric vehicles (EVs) and hybrid electric vehicles (HEVs) in recent years. However, it was urgent and important to remove the heat generated from the tractive lithium ion batteries during charge-discharge processes for its future application in EVs and HEVs. In this study, the heat release and indirect liquid cooling of tractive lithium ion batteries was investigated. The temperatures of batteries at different positions were recorded under different discharge rates and environmental temperatures. The results showed that indirect liquid cooling could effectively decrease the temperatures of battery. The decreasing ratios of temperature at different positions of battery were varied from 1.9% to 8.1%. It presented preferable cooling effects at the positive and negative of battery.
