基于AMESim的不同充电方式下磷酸铁锂电池老化仿真分析

Simulation Analysis of Lithium Iron Phosphate Battery Aging under Different Charging Modes Based on AMESim

摘要: 随着全球碳减排行动深入，交通领域电气化驱动新能源汽车数量高增，动力电池作为新能源汽车的主要动力来源，其老化过程直接影响汽车的高续航里程与使用年限。通过AMESim仿真建模软件，建立了针对动力电池老化问题的充电策略评估模型，对比在四种不同充电策略下电池的老化程度。仿真结果显示，在“早晨上班前充电”策略下电池老化仿真结果最佳，容量损失为3.59%；而在“有空就充”策略下，电池老化仿真结果最差，产生了7.54%的容量损失。

Abstract: As the global carbon emission reduction action is deepening, the electrification of the transport sector drives the high increase in the number of new energy vehicles, the aging process of the power battery, as the main power source of new energy vehicles, directly affects the high range and service life of the vehicle. Through AMESim simulation modeling software, a charging strategy evaluation model for the power battery aging problem was established to compare the aging degree of the battery under five different charging strategies. The simulation results show that the “charge in the morning before going to work” strategy has the best battery aging simulation results, with a capac-ity loss of 3.58%, while the “charge when free” strategy has the worst battery aging simulation re-sults, with a capacity loss of 7.54%.
