Various systems for cooling a battery cell array are described. In one example an energy storage system includes a housing enclosing a battery cell array, an evaporator, and a circulating pump. In another example, an evaporator is adjacent to battery cells to facilitate heat transfer. In another example, thermoelectric elements are positioned adjacent to battery cells to facilitate heat transfer.

System and method for thermally robust energy storage system

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.

Energy storage system for electric vehicles

Energy storage system for hybrid electric vehicle

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 comprised of one or more battery cells held in place between side rails and secured by end plates and mounting pins. The end plates also include flanges which secure the end plates behind the pins. The pin arrangement provides more secure holding and helps prevent torque loosening during operation. The battery array also includes cell retainers between each cell to reduce thermal transfer between cells, and an insulation liner between the battery cells and the side rails to improve creepage and clearance.

Pinned battery cell array for a hybrid electric vehicle

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 having at least one battery array located within the enclosure. The energy storage module includes a thermal pad disposed between the battery array and an interior surface of the primary enclosure. A heat sink is disposed on an exterior surface of the primary enclosure. The heat sink comprises a plurality of fins which may be disposed angularly with respect to a longitudinal axis of the primary enclosure. The height or length of the fins may be varied relative to a fan location to provide uniform cooling across the battery cells in the battery array. An enclosing plate is mounted exterior to the heat sink and defining an airflow cavity, wherein the enclosing plate directs air from the fan across the heat sink.

Conduction and convection cooled energy storage system

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.
