1. A battery diagnosis system, comprising:
a receiving unit that receives charge state information of a high voltage battery of a vehicle being charged including charging types of the high voltage battery;
a control unit that controls a current of the high voltage battery;
a measurement unit that measures a voltage change amount of the high voltage battery in which the current is controlled; and
a determination unit that determines the battery having the voltage change amount of an abnormal battery among the voltage change amounts of the battery measured in the measurement unit,
wherein the determination unit determines the battery having the voltage change amount of an abnormal battery in different ways depending on the charging types according to the charging state information,
wherein the control unit controls the current of the high voltage battery to a target current value based on the charging types of the high voltage battery included in the received charge state information, and
wherein the measurement unit measures the voltage change amount of the high voltage battery in which the current is controlled to the target current value.
