An energy storage module with one or more energy storage devices and a cooler on which the energy storage device is mounted in contact with the energy storage device. The cooler has one or more cooling fluid channels for circulating cooling fluid, the channels being in contact with a surface of the energy storage device, each cooling fluid channel being adapted to receive cooling fluid from a source of cooling fluid, extract heat from the energy storage device and return the cooling fluid to the source. At least a part of the cooling fluid channel includes a material having a melting point above 100° C.
