The invention relates to a system and method for recharging a low-voltage battery after dormancy of an electric vehicle. The system comprises a recharging condition editing module which is used for editing a basic condition that the low-voltage battery enters recharging and a stopping condition that the low-voltage battery quits recharging during charging, a monitoring module which is used for monitoring state information data of the recharging system, a judgment module which is used for judging whether the state information data, obtained by a detection module before the low-voltage battery is charged, of the recharging system meets the basic condition or not and judging whether the state information data, obtained by the monitoring module when the low-voltage battery is charged, of the recharging system meets the stopping condition or not, and a control module which is used for adjusting the DCDC to charge the low-voltage battery according to the result of the judgment module. The low-voltage battery in the
