随着汽车能耗标准的日益严苛，在部分工况下，低压蓄电池需要参与整车负载供电以降低整车能耗。在此场景下，蓄电池的充电接受能力显得尤为重要。影响充电接受能力的因素很多，包括板栅合金、负极添加剂、化成、充电MAP、使用环境等。文章通过对启停电池超充电接受机理分析及系列试验验证，探究多种因素对充电接受能力的影响，可通过改善正板栅合金成分、负极配方使用木素与腐殖酸组合、电池酸密度降低等手段来提升电池的充电接受能力，特别是短时大电流充电能力，从而满足车辆动能回收的要求。

With the increasingly stringent energy consumption standards of vehicles,in some working conditions,low-voltage batteries need to participate in the load power supply of the vehicle to reduce the energy consumption of the vehicle.In this scenario,the charging acceptance capacity of the battery is particularly important.There are many factors that affect the charging acceptance,including grid alloy,negative electrode additive,formation,charging MAP,use environment,etc.Through the analysis of the mechanism of over-charge acceptance of start-stop batteries and a series of tests,this paper explores the influence of various factors on the charge acceptance ability.The charge acceptance ability of batteries can be improved by improving the positive grid alloy composition,the combination of lignin and humic acid in the negative electrode formula,and the reduction of battery acid density,especially the short-time and high-current charging ability.Thus to meet the requirements of vehicle kinetic energy recovery.
