Abstract
A battery cell module includes a plurality of battery cells, in particular lithium-ion battery cells which are arranged in a packet and each of which has a substantially prismatic cell housing. Each cell housing has the three dimensions: housing height, housing width, and housing depth. Two of the dimensions are carried out in a substantially identical manner in all the battery cells of the battery cell module, and the third dimension is carried out differently in at least two battery cells of the battery cell module. A battery includes said battery cell module and a motor vehicle includes said battery.
Claims9
A battery cell module, comprising:
- a plurality of battery cells substantially forming a rectangular cuboid and each having a respective substantially prismatic cell housing, wherein:
- each respective cell housing has three dimensions:
- a housing height, a housing width and a housing depth,
- two dimensions of the three dimensions are substantially identical for all of the battery cells of the plurality of battery cells, and a third dimension of the three dimensions differs between at least two battery cells of the plurality of battery cells, and
- the plurality of battery cells are arranged adjacent to each other in a longitudinal direction of the battery cell module and the third dimension is parallel to the longitudinal direction.
A battery comprising:
- at least one battery cell module including:
- a plurality of battery cells each having a respective substantially prismatic cell housing, wherein:
- each respective cell housing has a first extent along a first axis, a second extent along a second axis, and a third extent along a third axis,
- each of the third extents are aligned on the third axis,
- each of the first axis, the second axis and the third axis is orthogonal to the other of the first, second and third axis,
- each of the first extents and the second extents are substantially identical, and the third extent of a first of the plurality of battery cells differs substantially from the third extent of a second of the plurality of battery cells, and
- the plurality of battery cells are arranged adjacent to each other in a longitudinal direction of the at least one battery cell module and the third dimension is parallel to the longitudinal direction.
A motor vehicle which can be driven by an electric motor, comprising:
- at least one battery having at least one battery cell module including:
- a plurality of battery cells substantially defining a rectangular cuboid and each having a respective substantially prismatic cell housing, wherein:
- each respective cell housing has three dimensions:
- a housing height, a housing width and a housing depth,
- two dimensions of the three dimensions are substantially identical for all of the battery cells of the plurality of battery cells, and a third dimension of the three dimensions differs for at least two battery cells of the plurality of battery cells,
- the at least one battery is connected to a drive system of the motor vehicle, and
- the plurality of battery cells are arranged adjacent to each other in a longitudinal direction of the at least one battery cell module and the third dimension is parallel to the longitudinal direction.
