A battery pack has a plurality of battery stacks, a case, and a thermal insulation cover. The case accommodates the plurality of battery stacks. The thermal insulation cover is arranged so as to expose an outer surface of at least one battery stack from among the plurality of battery stacks inside the case, and to cover an outer surface of a battery stack that is adjacent to the exposed battery stack. A difference obtained by subtracting an amount of removed heat from an amount of heat generated during heat generation is greater in the battery stack that is exposed from the thermal insulation cover than in the battery stack that is covered by the thermal insulation cover.

An assemblage having a thermally insulating switch and a thermal insulator for constituting an electrical conductor passthrough through the thermal insulator. The thermal insulator insulates an inner space from an outer space, the assemblage having inner connector on the side of the inner space and outer connector on the side of the outer space, which are electrically conductively connectable by the switch. The assemblage has a control unit for controlling the thermally insulating switch, a current flowing through the switch is detectable by the control unit, the switch is controllable by the control unit in such a way that the switch is actuatable only in a substantially zero-current state, and the switch is disposed in the thermal insulator in such a way that thermal insulation between the inner connector and the outer connector is accomplished by way of the switch in the open state.

An electrical energy storage device includes prismatic energy storage cells arranged adjacent to one another such that interfaces of adjacent storage cells run at a distance from one another such that the interfaces of the adjacent storage cells form an intermediate space. A respective first layer is arranged between the interfaces of adjacent storage cells, the first layer abutting one of the two interfaces of the adjacent storage cells under pressure. Either the respective first layer also abuts the second of the two interfaces of the adjacent storage cells under pressure, or a second layer is arranged between the interfaces of adjacent storage cells, the second layer abutting the second of the two interfaces of the adjacent storage cells under pressure. A heat-conducting device is arranged in or between the first layer and the second layer is conducted out of the intermediate space between the adjacent storage cells.

A battery pack assembly or enclosure comprises one or more batteries having an electrochemical cell and an enclosure having at least an outer wall configured to create a sealed volume of space substantially around the batteries. An atmosphere of the volume of space comprises gas having a thermal conductivity less than 0.018 watts per meter per degree Celsius. This atmosphere of gas provides an insulative layer between the outer wall of the enclosure and the batteries. With this insulative layer, the battery pack assembly can be subjected to autoclaving without damaging the batteries. The battery pack assembly can be used to power surgical tools or other devices that are subjected to autoclaving.
