摘　　要：随着纯电动汽车向智能化汽车发展,汽车低压系统变得越来越庞大,在OFF挡的用车场景也随之变多,这些场景下的高压系统处于不工作的状态,由于低压系统由低压蓄电池供电,导致电池多耗少补,亏电的概率变大。文章基于电气架构及蓄电池特性,对智能补电功能进行深入研究,并提出一种低成本智能补电功能参数的设置思路,对智能补电策略的进入条件、保持条件、退出条件等设计进行优化。With the development of pure electric vehicles to intelligent vehicles,automotive low voltage system has become more and more large.In the off-gear car scenes also become more and more,the high-voltage system in these scenes is not working,because the low-voltage system is powered by the low-voltage battery,resulting in the probability of battery loss increases.Based on the electrical architecture and battery characteristics,this paper makes an in-depth study of the intelligent recharge function,and puts forward a low-cost intelligent recharge function parameter setting idea,and optimizes the design of the entry condition,hold condition and exit condition of the intelligent recharge strategy.
