Abstract
A battery device comprises one or more battery modules, one of the respective battery modules comprising the following: a frame element, a base element and a plurality of battery cell.
Claims16
A battery device, the battery device comprising one or more battery modules,
- at least one of the battery modules comprising:
- a frame element;
- a base element;
- a receiving space comprising a plurality of battery cells;
- one or more stacking protrusions protruding in a stacking direction of the battery device;
- one or more stacking recesses, in which stacking recesses stacking protrusions of a frame element of an adjacent battery module can be received;
- and
- a sealing element in addition to the one or more stacking protrusions;
- wherein
- the frame element comprises a double wall, the double wall comprising an inner wall element and an outer wall element, wherein the inner wall element is closer to the receiving space than the outer wall element, and
- wherein at least part of at least one stacking protrusion of the one or more stacking protrusions and/or at least part of at least one stacking recess of the one or more stacking recesses is in a radial direction offset from the inner wall element towards or onto the receiving space or in a radial direction offset from the outer wall element away from the receiving space.
A battery device, the battery device comprising at least two battery modules which include a first battery module and a second battery module, the first battery module comprising:
- a frame element of the first battery module;
- a base element of the first battery module;
- and
- a plurality of battery cells of the first battery module, wherein
- the frame element of the first battery module comprises a double wall, the second battery module comprising:
- a frame element of the second battery module;
- a base element of the second battery module;
- and
- a plurality of battery cells of the second battery module,
- wherein the first battery module comprises two compressible sealing elements, a first sealing element of the first battery module being compressed between the frame element of the first battery module and the base element of the first battery module, wherein a material of the first sealing element is different from the materials of the frame element of the first battery module and the base element of the first battery module, and a second sealing element of the first battery module being compressed between the frame element of the first battery module and the base element of the second battery module, wherein a material of the second sealing element is different from the materials of the frame element of the first battery module and the base element of the second battery module.
