Abstract

With the problem of environmental pollution and energy shortage is becoming increasingly serious, researches on electric vehicle (EV) are getting more and more attention. As an important energy source of EV, the working status of power battery will affect the performance of the vehicle. The performance and lifespan of battery is tied up with its temperature distribution. In this paper, experiment bench is established to study the impact of heat pipe on the temperature distribution in the battery pack. As to the experiment bench, ten electric heating plates are used to imitate the power batteries in the pack, and the heat of battery pack is soaked up by the composite phase change materials (PCM) of paraffin and graphite, and the heat is transferred outside by four heat pipes. The research shows that it has positive cooling effect on the battery pack to adopt PCM-heat pipe coupled system, which can basically ensure the battery is operating within the best temperature range. Compared with the pure PCM system, the using of heat pipes can reduce the temperature rise of the battery up to 10 . Meanwhile, the temperature distribution of PCM-heat pipe coupled system is more uniform than the system without heat pipes, which avoids having a negative effect on the performance and lifespan of the battery.
