Working in the extreme condition such as high temperature and discharge rate, causes the generated heat shapely increasing and rising of temperature of power battery. Further influence the cell performance. It is important to efficiently dissipate heat. In this paper, a minichannel cooling system can be designed to cope with the problem. Moreover, creating numerical model to study different placement, ambient temperature and coolant inlet properties how to function on the system. The results express the system be placed at vertical direction can obtained a good temperature effect, only sacrificing few of pump energy than placed at horizontal. The results show the variation of ambient temperature has little effect on the temperature contribution of battery module, and the temperature of the battery pack is presented linear with the coolant inlet temperature. The temperature of battery pack is decrease and the uniformity is improved by increasing the inlet velocity of the coolant. In the end, increasing the height of the channel are a better scheme through the process of structure optimization.
