A charging management apparatus according to the present disclosure includes a first main relay connected between a positive electrode terminal of a battery pack and a first charging terminal of a charging connector; a current regulator including a precharge relay and a resistance regulation circuit connected in series, the current regulator connected in parallel to the first main relay; a voltage sensor to measure a voltage of the battery pack; a current sensor to measure a current of the battery pack; and a controller to execute a second charging process in which the first main relay is controlled into an on state and the precharge relay is controlled into an off state in response to a first switching condition being satisfied during a first charging process in which the first main relay is controlled into the off state, the resistance regulation circuit is set to a first resistance value and the precharge relay is controlled into the on state. The controller executes a third charging process in which the resistance regulation circuit is set to a second resistance value, the precharge relay is controlled into the on state and the first main relay is controlled into the off state, in response to a second switching condition being satisfied during the second charging process.
