Abstract
A method and a charger for charging a rechargeable energy storage device of an electronic device via a charging interface. A stored charging voltage is applied to the charging interface at the beginning of a charging operation. A resulting charging current flowing through the charging interface is detected during the charging operation and a current state of charge of the energy storage device is determined based on the detected charging current. A voltage level for the charging voltage is determined for the specific state of charge, and the charging voltage is set to the determined voltage level.
Claims11
A method for charging a rechargeable energy storage device of an electronic device via a charging interface, the method comprising:
- at a beginning of a charging operation, applying a stored charging voltage to the charging interface;
