摘　　要：为解决锂电池组热失控问题,采用逻辑门限值法设计了温升控制策略,并基于AMESim与MATLAB/Simulink的联合仿真调试,对锂电池组在不同道路工况和不同环境温度下的最高温度及电芯间最大温差进行了研究,仿真结果表明,设计的温升控制策略能保证锂电池组最高温度≤45℃,电芯间最大温差≤5℃,达到了预期的控制目标,具有一定的可行性,有利于保证锂电池组的高性能、长寿命、低危险运行。In order to solve the problem of thermal runaway of lithium-ion battery pack, a temperature rise control strategy is designed with the logic threshold method. Based on the co-simulation of AMESim and MATLAB/Simulink, the maximum temperature of lithium batteries and the maximum temperature difference between cells under different road conditions and different ambient temperatures are studied. The result shows that the designed temperature rise control strategy can ensure the maximum temperature of lithium batteries less than or equal to 45 ℃, and the maximum temperature difference between cells less than or equal to 5 ℃, it can achieve the expected control objectives, so it has good feasibility, which ensures the high performance, long service life and low risk of lithium batteries.
