摘要
低温情况下动力电池组的性能大幅度下降,直接影响电动汽车的行驶里程。介绍了国内外关于电池组加热方法的研究进展;阐述了各种加热方法的优缺点、应用要求;指出加热膜和PTC加热板是当前应用的加热方式,液体加热的应用是今后的主要研究方向;提出电池的加热与散热应当结合设计,同时兼顾电池箱的保温措施与加热控制策略。
Under low temperature, the performance of the battery pack is greatly reduced, which directly affects the application of the electric vehicle. The paper introduced the research progress on battery heating method, and expounded the advantages and disadvantages of various heating methods. It is concluded that heating film and PTC heating plate are the main ways in the current application, and liquid heating is the main research directions in the future; heating and cooling of the battery should be combined with the design, taking into account the battery box insulation measures and heating control strategy.
