Publication number: 20210126302Abstract: A battery pack includes a heating element, which can be an electric ribbon-type heating element. The heating element can be switched on when pack temperatures are near or fall below the minimum discharge or charge operating temperatures. The heating element can simultaneously function to heat the battery cells and as a separator for a group of cells bound together to form a lightweight battery pack. With such a configuration, the disclosed ribbon-type heater is less prone to damage due to vibration of the battery pack. The heating element can be self-powered by the battery pack cells with DC power or can be externally AC or DC powered. The disclosed heating element is self-contained and controlled by the battery pack BMS. In installations where heating elements are not desired, inactive separator elements can be alternatively provided, thereby reducing costs and avoiding the need to reconfigure other components of the battery pack.Type: ApplicationFiled: October 23, 2020Publication date: April 29, 2021Inventors: Joel Hooper, Peter Lex, Tod Tesch
