Problems solved by technology

Parallel connection of multiple single cells is an effective way to increase the capacity of the battery module. At present, the parallel connection of single cells in the battery module is generally directly connected in parallel with busbars made of red copper that can withstand high currents. However, once the parallel connection of the battery pack When there is an internal short circuit of a single battery, it will cause an external short circuit of other single batteries, and the safety is questionable

Abstract

The invention discloses a vehicle battery module, comprising a plurality of single cells and an even number of busbars, the single cells are arranged along a first direction on the same pole and on the same side, and each of the busbars includes a busbar row and a safety element, the bus bar is connected to the positive pole or the negative pole of the single battery through the safety element. Due to the adoption of the vehicle battery module of the present invention, it has the advantages of small volume, high energy density, high power characteristic and good safety.

Description

technical field [0001] The invention relates to a battery module, in particular to a vehicle battery module. Background technique [0002] The battery module plays the role of storing energy in the electric vehicle, in order to meet the power, driving range and safety performance of the electric vehicle. Battery modules are required to have high power characteristics, energy density, and safety and reliability. Before the single battery technology has achieved a breakthrough, reducing the module volume is a direct way to increase the energy density of the module. Parallel connection of multiple single cells is an effective way to increase the capacity of the battery module. At present, the parallel connection of single cells in the battery module is generally directly connected in parallel with busbars made of red copper that can withstand high currents. However, once the parallel connection of the battery pack When there is an internal short circuit of a single battery, i...
