Abstract

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.

First claim

What is claimed is:

1. An assemblage, comprising:
a thermally insulating switch and a thermal insulator for constituting an electrical conductor passthrough through the thermal insulator for electrical connection of a thermally insulated electrochemical battery to a load, the thermal insulator thermally insulating an inner space from an outer space the assemblage having inner connector on a side of the inner space, the assemblage having outer connector on a side of the outer space, and the switch, in a closed state electrically conductively connecting the inner connector to the outer connector, and in an open state electrically disconnecting the inner connector from the outer connector; and
a control unit to control the thermally insulating switch, a current flowing through the switch being detectable by the control unit, the switch being controllable by the control unit in such a way that the switch is actuatable only in a substantially zero-current state;
wherein 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.

2. The assemblage as recited in claim 1 , wherein at least one of the inner connector and the outer connector are at least partly recessed into the thermal insulator.

3. The assemblage as recited in claim 1 , wherein the switch is disposed inside the thermal insulator in such a way that the thermal insulator is disposed in part between the switch and at least one of the inner space and the outer space.

4. The assemblage as recited in claim 1 , wherein the thermal insulator has an inner wall and an outer wall having a cavity disposed therebetween.

5. The assemblage as recited in claim 4 , wherein at least one of: (i) the inner connector is passed through the inner wall, and (ii) the outer connector is passed through the outer wall.

6. The assemblage as recited in claim 4 , wherein the switch is disposed in the cavity.

7. The assemblage as recited in claim 4 , wherein a partial vacuum is in the cavity.

8. The assemblage as recited in claim 1 , wherein the switch is of multiple-pole configuration.

9. The assemblage as recited in claim 1 , wherein the switch is one of a trapezoidal or a conical construction, and has switching contacts that are disposed along the cone.

10. A thermally insulated electrochemical battery and a battery management system for controlling the thermally insulated battery, the thermally insulated battery having an assemblage having a thermally insulating switch and a thermal insulator for constituting an electrical conductor passthrough through the thermal insulator for electrical connection of the battery to a load, the thermal insulator thermally insulating an inner space from an outer space the assemblage having inner connector on a side of the inner space, the assemblage having outer connector on a side of the outer space, and the switch, in a closed state electrically conductively connecting the inner connector to the outer connector, and in an open state electrically disconnecting the inner connector from the outer connector, and a control unit to control the thermally insulating switch, a current flowing through the switch being detectable by the control unit, the switch being controllable by the control unit in such a way that the switch is actuatable only in a substantially zero-current state, wherein 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;
wherein the thermally insulated battery has an energy reservoir that is disposed inside the inner space surrounded by the thermal insulator, the energy reservoir being connected in the inner space to the inner connector, the thermally insulated battery being at least one of chargeable and dischargeable via the outer connector in a closed state of the switch, and the function of the control unit being executable by the battery management system.
