Abstract: There is disclosed an electrical device including a battery pack, a pressure sensor for measuring a volume change of the battery pack, a voltage sensor in electrical communication with a positive terminal and a negative terminal of the battery pack, a temperature sensor positioned in a cell of the battery pack, and a battery management system. The battery management system includes a controller in electrical communication with the pressure sensor, the voltage sensor, and the temperature sensor, the controller being configured to execute a program stored in the controller to determine a state of charge percentage of the battery pack based on a pressure reading from the pressure sensor, a terminal voltage reading from the voltage sensor, and a temperature reading from the temperature sensor.

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.
