Abstract

The invention relates to the technical field of energy machinery, and provides a battery module and an engineering vehicle, the battery module comprises a plurality of battery cell groups and a plurality of first busbars, each battery cell group comprises at least two single battery cells, the first busbars are used for connecting adjacent battery cell groups in parallel, two opposite sides of each first busbar respectively comprise at least two first connecting terminals, and the first connecting terminals are connected with the battery cell groups in parallel. The first connecting terminals are respectively used for connecting the single battery cells in the battery cell group in series. A plurality of single cells can be connected in parallel through the first busbar to form a cell group, and adjacent cell groups can be connected in series through the first busbar and connected in parallel in the transverse direction of the battery module, so that the current-carrying cross sections of the busbars are increased in an equal proportion along with the number of the single cells connected in parallel, and the grouping of the cell module is not limited by the number of the single cells connected in parallel; the multi-group parallel high-current-carrying heat safety requirement is met, and the number of voltage acquisition points is reduced by more than half by adopting a parallel-to-serial connection mode, so that the overall cost of the battery module is reduced.

Description

technical field [0001] The invention relates to the technical field of energy machinery, in particular to a battery module and an engineering vehicle. Background technique [0002] With the promotion of pure electric vehicles, the electrification of construction vehicles is also gradually promoted and applied. Compared with passenger vehicles, construction vehicles have greater requirements for battery capacity, and thus higher requirements for bus load flow. The battery module cannot meet the capacity requirements of the construction vehicle. SUMMARY OF THE INVENTION [0003] Embodiments of the present invention provide a battery module and an engineering vehicle, which are used to solve the technical problem that the battery module in the prior art cannot meet the capacity requirement of the engineering vehicle. [0004] In a first aspect, an embodiment of the present invention provides a battery module, including: a plurality of battery cell groups, each of which inclu...
