Claims23
A method for charging a battery, wherein current pulses are supplied to the battery, wherein each pulse is followed by a rest period during which no current is supplied to the battery, and wherein the state of charge of the battery is determined during the rest period.
A battery charging device, comprising:
- a power supply unit adapted to supply a constant current to a battery at a predetermined current value;
- a control unit adapted to control the current supply to the battery such that current pulses are supplied to the battery, wherein each pulse is followed by a rest period during which no current is supplied to the battery, and wherein the control unit is further adapted to determine the state of charge of the battery during the rest period.
