Abstract
Embodiments include methods for charging a battery of an electrical system. The electrical system includes the battery, a battery charger, and a controller. The battery charger is adapted to produce an output power in response to a control signal from the controller. The controller is adapted to control a battery charging process by determining a temperature of the battery pack, determining a voltage setpoint for the battery charger based on the temperature, and providing the control signal to the battery charger. According to an embodiment, when the temperature of the battery exceeds a first temperature value, the battery charging process is temporarily suspended prior to satisfying a charging termination criterion. Determining the temperature of the battery is repeated, and when the temperature of the battery is less than a second temperature value, the battery charging process is resumed.
