Claim Text:
1. A system for preventing overshoot at the beginning of slow charging, comprising: a memory configured to store program instructions; and a controller configured to execute the program instructions, the program instructions when executed configured to: receive initial charging command information during slow charging from electric vehicle supply equipment (EVSE); generate initial charging information for preventing overshoot using the initial charging command information; operate a charger configured to charge a battery using the initial charging information, wherein the initial charging information is set to be an amount less than an initial amount of charging of the initial charging command information; and operate a battery management system (BMS) to generate sensing information, by the BMS sensing the charger, and charge the battery with the initial amount of charging of the initial charging command information based on an originally set algorithm of the EVSE after a preset time based on whether the charging of the battery is stabilized using the sensing information, wherein the initial charging command information includes initial current command information.
