Abstract

The hybrid battery system includes a primary battery pack, a secondary battery pack, a battery control unit, a battery pack positive terminal, and a battery pack negative terminal. The battery control unit includes a management module and a variable resistor. The primary battery pack supplies power at lower temperatures, while the secondary battery pack supplies power at higher temperatures. The primary battery pack is unsafe at higher temperatures, and the primary cells within the primary battery pack are modified to mitigate the dangers that previously rendered the primary battery pack unusable in a hybrid battery pack at higher temperatures. The invention includes the method of safely operating the hybrid battery system with the modified primary battery cells of the primary battery pack.
