摘要：
To explore Battery Thermal Management (BTM) for Electric Vehicle (EV), a heat exchanger of battery pack is designed using aluminum flat tube bank and flexible graphite. The investigation focuses on the thermal characteristics of the battery pack in the BTM process, such as the temperature variation and temperature uniformity of the battery pack and cell surface etc. The computation results show that, without flexible graphite, the heat exchange of flat tube banks in battery pack and flat tubes on cell surface present better consistency, but the temperature difference is larger for different measure points in the same battery cell. In addition, the battery cooling speed rises obviously, and the temperature uniformity of cell surface is significantly improved. The results indicate that the battery pack obtains well cooling effect, and it also realizes further lightweight compared with full-contact liquid cooling plate. © 2017, Editorial Board of Jilin University.
