Abstract
An energy storage system comprising at least one energy storage module implemented as a sealed or submersible unit and adapted to supply electrical energy to a hybrid vehicle. The energy storage module comprises an enclosure and at least one battery array located within the enclosure. The energy storage module includes a pressure relief panel held in place by springs that allows battery gases to escape if gas pressures reach a predetermined threshold. Pressure in the enclosure compresses the springs causing the pressure relief panel to temporarily move outward until pressure is relieved at which time the springs force the pressure relief panel to reseal the enclosure.
