Embodiment Construction

[0033] Figure 1 to Figure 4 A schematic diagram of a battery device 1 for a hybrid or electric vehicle according to the invention is shown. The accumulator device 1 has a plurality of rigid, in particular prismatic, battery cells 2 comprising support surfaces 3 facing each other, the battery cells 2 facing each other with the support surfaces 3 being stacked in a stacking direction 4 to form a battery pack 5. The battery arrangement 1 also has a cooling device 6 comprising a plurality of cooling elements 7 and through which a cooling fluid can flow, as well as a fluid distributor 8 . A respective cooling element 7 is arranged between adjacent battery cells 2 and adjoins the bearing surface 3 of the respective adjacent battery cell 2 in order to transfer heat. The cooling element 7 and the battery cells 2 are clamped together in the battery pack 5 in the stacking direction 4 . In this exemplary embodiment, corresponding cooling elements 7 are arranged in battery pack 5 in su...

Abstract

The invention relates to an accumulator arrangement for a hybrid or electric vehicle. The accumulator arrangement may include a plurality of rigid battery cells and a cooling device. The plurality ofbattery cells may have a plurality of bearing surfaces and may be stacked in a stacking direction to form a battery block. The cooling device may include a plurality of cooling elements through whicha cooling fluid is flowable. A respective cooling element may be arranged between adjacent battery cells and clamped thereto. The respective cooling element may abut against a bearing surface of eachof the adjacent battery cells facilitating a transfer of heat. The respective cooling element may further include a frame extending around the bearing surface of each of the adjacent battery cells ina circumferential direction such that an interior of the respective cooling element is disposed between the frame and the adjacent battery cells.

Description

technical field [0001] The invention relates to a battery arrangement for a hybrid or electric vehicle according to the preamble of claim 1 . Background technique [0002] A battery arrangement or traction battery for a hybrid or electric vehicle usually comprises a plurality of individual battery cells which are combined to form a battery module or more battery modules. The individual battery cells are electrically interconnected in corresponding battery modules and provide energy for a hybrid or electric vehicle. In the further development of traction batteries, shorter charging times are increasingly sought, which leads to high thermal loads on the traction batteries. Therefore, effective temperature control of the individual battery cells in the traction battery is required. [0003] For the respective battery module, for example, a cooling device can be provided for this purpose, which cools the respective battery cell on the current collector. Thus, the cooling devi...
