COOLING SYSTEM
An energy storage module cooling system having a source of cooling fluid; and a fluid conduit for supplying the cooling fluid to one or more energy storage modules. Each energy storage module has carriers for a plurality of energy storage devices; the carriers further have cooling channels forming a cooler for each energy storage device. One surface of each energy storage device is in thermal contact with the cooler; and another surface of the energy storage device is provided with a thermally insulating layer, whereby heat transfer between adjacent energy storage devices is reduced.
