Abstract
A charging system includes a battery pack including at least one battery cell and a battery management module, and a charger including a connector configured to detect a connection with the battery pack, a communicator configured to communicate with the battery management module, and a controller configured to control charging of the battery pack. The controller of the charger is configured to output a wake-up voltage when the connection with the battery pack is detected through the connector, receive a value of a battery voltage from the battery management module through the communicator, determine a charging start voltage based on the value of the battery voltage, and start charging the battery pack after outputting the charging start voltage.
