Abstract:
There is disclosed an electrical device and a method in which a battery is warmed up when operating from a sub-zero temperature. The electrical device may include a battery; an electrical storage element; and a battery management system including a controller in electrical communication with the battery and the electrical storage element. The controller can be configured to execute a program stored in the controller to shuttle energy between the battery and the electrical storage element until a power capability threshold of the battery has been reached, Shuttling the energy raises a temperature of the battery to meet power demand.
