Through the analysis of the result of the sectional fixed currents’ chargingthe control scheme has been adjusted: The control s parameters of sectional fixed currents have been defined according to capacity gradient; several volumes of secti onal fixed currents has been appropriately reduced so as to lower the capacity gradient, meanwhile, battery temperature has been set as the charg ing monitoring security control sparameters. The adjusted charging experiment result indicates t
