NOVELTY - The module has a tempering body (10) comprising two fluid port openings (28). An outer surface of a wall plate (12) is provided in thermal contact with an energy storage cell of an energy storage device, and outer surface of another wall plate (14) is formed opposite to the former outer surface. A meander-shaped channel is formed between the outer surfaces of the wall plates, and interconnects the openings for guiding a heat carrier medium to the openings. The openings are formed at two outer surfaces of the wall plates. A channel plate (16) is arranged between the wall plates.    USE - Tempering module for heating and cooling an energy storage cell of an energy storage device of a vehicle e.g. electric car and hybrid car, and a portion i.e. stator winding, of an electric machine (all claimed) i.e. electromotor, of the vehicle. Uses include but are not limited to a lithium ion battery cell, a nickel metal hydride battery cell, a super cap cell and an ion silicon cell.    ADVANTAGE - The fluid port openings are formed at the outer surfaces of the wall plates, so that the openings are displaced against each other in mounted state of the tempering module, thus enabling stacking of the energy storage cells and the tempering modules in an easy manner, and hence reducing installation space requirement of the tempering module while enabling heating and cooling of the energy storage cells and the electric machine in an efficient manner. The energy storage device is mounted easily.    DETAILED DESCRIPTION - The heat carrier medium is fluid, gas i.e. air, or liquid i.e. water, and the energy storage cell is in rectangular, prismatic, coffee bag and cylindrical shape. An INDEPENDENT CLAIM is also included for an energy storage device.    DESCRIPTION OF DRAWING(S) - The drawing shows a schematic perspective view of a tempering body of a tempering device.
