Abstract

A battery, in particular a vehicle battery for a vehicle which is at least electrically drivable, including a battery housing, and at least one first battery module, the first battery module including at least one battery cell, and including at least one battery terminal for connecting the battery to a vehicle. The battery includes at least one second battery module, including at least one battery cell, inside the battery housing, the second battery module being connectable to the first battery module and energy being thereby transmitted between the battery modules, at least one thermal insulation element at least largely surrounding the first battery module, whereby the first battery module is thermally insulated and thermally separated from the second battery module.

First claim

What is claimed is:

1. A battery for a vehicle, which is at least electrically drivable, comprising:
a battery housing;
at least one first battery module having at least one battery cell;
at least one battery contact for connecting the battery to a vehicle; and
at least one second battery module including at least one battery cell, inside the battery housing, the second battery module being connectable to the first battery module, wherein energy is transmittable between the battery modules;
wherein at least one thermal insulation element surrounds the first battery module and is flush with the battery housing, and wherein the first battery module is thermally insulated and thermally separated from the second battery module,
wherein the second battery module is surrounded by a separate thermal insulation element, and wherein the second battery module is thermally insulated and thermally separated from the first battery module,
wherein the first battery module and the second battery module each include at least one heating element, wherein the at least one heating element of each of the first battery module and the second battery module are electrically connected, and wherein thermal management of the other one of the first and second battery modules is provided with the at least one heating element,
wherein the at least one battery contact includes battery contacts situated on the battery housing, which is shared by the at least one first battery module and by the at least one second battery module, the battery contacts being connected at least to the first battery module, and
wherein the battery modules are dimensioned in different sizes, so that the battery modules have different capacitances, so that a smaller one of the battery modules requires less heating energy than the other of the battery modules, wherein in a resting state, energy is transmitted from the other one of the battery modules to the heating element of the smaller one of the battery modules, and wherein in an operating state, energy is transmitted from the smaller one of the battery modules to the heating element of the other one of the battery modules.

2. The battery as recited in claim 1 , wherein the at least one heating element transmits energy at least one of electrically and fluidically.

3. The battery as recited in claim 1 , wherein the at least one heating element is connected to a control unit, by which the heat output may be at least one of regulated and controlled.

4. The battery as recited in claim 1 , wherein the battery housing is formed at least partially by the insulation element.

5. The battery as recited in claim 1 , wherein the insulation element is movably situated on at least one of the battery module and the battery housing.
