1. An energy storage system, comprising:
- a first energy storage module adapted to supply electrical energy to a hybrid vehicle, the first energy storage module comprising;
a primary enclosure with a battery array located within the primary enclosure, the battery array having multiple battery cells;
a vent in the primary enclosure, and a pressure relief panel held adjacent to the vent, the pressure relief panel operable to limit internal pressure of the primary enclosure, wherein at least one of the battery cells in the battery array has a battery vent for releasing battery gases into the primary enclosure;
a compliant seal positioned around the vent and at least one spring operable to maintain the pressure relief panel adjacent the vent in the primary enclosure;
a heat sink disposed on an exterior surface of the primary enclosure, the heat sink comprising a plurality of fins disposed angularly outward with respect to a longitudinal axis of the heat sink, a first portion of the plurality of fins having a first height, and a second portion of the plurality of fins having a second height;
wherein the first height is lower than the second height; and
wherein a central cavity is defined by the first height and the second height of the plurality of fins, the central cavity directing a flow of air from a first end of the heat sink toward a second end.

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 an enclosure, at least one battery array located within the enclosure, and an energy storage controller module located within the enclosure and electrically connected to the battery array. The energy storage module further comprises a compliant tipped thermistor which may be installed within a flexible clip. The thermistor is positioned to monitor the temperature of one or more of the batteries within the energy storage system.
