摘　　要：动力电池的电性能、安全性和循环性能都与电池的工作温度密切相关。在一定的散热条件下,动力电池的温度主要取决于其本征产热和比热容热物性参数特性。上述热物性参数可通过等温量热法(IBC)和绝热量热法(ARC)进行精确的量化测试。主要从测试原理、模拟场景、测试样品尺寸、数据分析过程和测试结果5方面,针对上述2种测试方法的异同进行对比分析,以指导电池热管理系统设计中热物性参数的合理获取。The electrical performance,safety and cycling performance of power batteries are closely related to the battery’s operating temperature.Under certain heat dissipation conditions,the temperature of the power battery mainly depends on its intrinsic heat generation and specific heat capacity characteristics.The above thermophysical parameters can be accurately tested by isothermal and Accelerating Rate Calorimetry(ARC)methods.This article mainly compares and analyzes the similarities and differences of the two test methods from the aspects of test principles,simulation scenarios,test sample sizes,data analysis process,and test results to guide the reasonable acquisition of thermal physical parameters in the design of battery thermal management systems.
