Abstract:
An energy storage system comprising at least one energy storage module adapted to supply electrical energy to a hybrid vehicle. The energy storage module comprises a primary enclosure, at least one battery array located within the primary enclosure, and an energy storage controller module located within the primary enclosure and electrically connected to the battery array. The energy storage controller module is further connected to a hybrid control module of the hybrid vehicle by a low voltage connecter. A high voltage junction box is attached to a first end of the primary enclosure and having a plurality of high voltage connection terminals. At least one of the high voltage connection terminals is configured to receive a high voltage conductor connected between the energy storage module and an inverter of the hybrid vehicle. When multiple energy storage modules are used in conjunction, one module functions as a master module and one module functions as a slave module.
