【Abstract】With the increasingly stringent energy consumption standards of vehicles，in some working conditions， low-voltage bateries need toparticipate intheload power supplyof the vehicletoreduce theenergyconsumptionof the vehicle.In thisscenario，thecharging acceptancecapacityofthebattery is particularlyimportant.There are many factors that affect the charging acceptance，including grid alloy，negativeelectrodeadditive，formation，charging MAP，use environment，etc.Through the analysis of the mechanism of over-charge acceptance ofstart-stop bateries andaseriesof tests，this paper explores the influence of various factors onthecharge acceptance ability.Thecharge acceptance ability of batteriescan be improvedby improving the positive grid allycomposition，thecombinationof ligninand humicacid in the negative electrode formula，and thereductionof batery aciddensity，especially the short-timeand high-current charging ability.Thus to meet the requirements of vehicle kinetic energy recovery.

【Key words】 start-stop battery； charge acceptance；positive grid；additives；acid density
