    摘要:

    针对动力电池在低温环境下无法直接进行充电的问题,以液冷动力电池系统为研究对象,在大量动力电池充放电数据的基础上,结合动力电池的低温加热和保温需求,构建了液冷动力电池包低温加热和保温系统,设计了动力电池的充电和加热流程.根据传热学原理,结合动力电池生热计算理论公式,建立了动力电池的生热仿真计算模型,利用仿真计算工作来模拟分析动力电池低温加热系统的加热效果.通过在NEDC循环工况下的仿真和试验,验证了液冷结构动力电池包低温加热系统很好地满足了动力电池包低温环境下的加热和保温要求,具有良好的应用性.

    Abstract:

    In order to solve the battery charge problem under low temperature, liquid cooling battery system was analyzed and studied, and thermal management with heating and preservation was designed. According to the battery low temperature test data and the requirement of battery heating and preservation, battery heating calculation model was proposed on the basis of the theory formula. The performance of battery heating system was studied by the proposed model. Optimization design of the liquid cooling control system was also investigated according to the analysis results. The results show that the liquid cooling battery management system exhibits excellent performance of low temperature heating and preservation.
