Study On Heat Transfer Performance Of A Liquid Cooling Power Battery

With the development of new energy vehicles, thermal management of power batteries has become a hot research topic. Power battery thermal management has a very important impact on battery life, safety, charging, and other performance. In this paper, the heat transfer performance of a cooling process is studied by establishing a three-dimensional thermal management model of power battery. The results showed that the proportion of heat in the battery taken directly from the coolant was 91.6%, and the proportion of heat absorbed and dissipated into the environment by the components outside the cell by heat transfer and so on was 8.6%.
