Claim 0:
1. A thermal regulating unit for regulating the temperature of a pouch cell battery, the thermal regulating unit being formed as a container having:
a spacer element which substantially completely fills the unit and includes one or more internal cooling channels for conveying a liquid coolant through the unit;
a flexible outer covering which contains the spacer element and the one or more internal cooling channels; and
inlet and outlet ports which penetrate the flexible outer covering for respectively providing liquid coolant to and removing the liquid coolant from the one or more internal cooling channels; wherein
the flexible outer covering forms a substantially flat major external surface of the unit for pressing against a major external surface of the pouch cell battery such that the unit and the pouch cell battery can be held in face-to-face contact;
the spacer element and the one or more cooling channels are arranged in the flexible outer covering such that when the liquid coolant is pressurized, the liquid coolant causes the unit to expand and press against the major external surface of the pouch cell battery, the spacer element limiting the expansion of the unit; and
the container is a bag-like container and the flexible outer covering forms an outer surface of the bag-like container.
