Background Art
[4]
The current global automotive industry faced with energy and the environment of the great challenges; high energy utilization rate, no pollution to the environment of a pure electric vehicle has increasingly become the future direction of the development of the automotive industry. As a pure electric vehicle of the core part, the power performance of the battery will directly affect the performance of the whole pure electric vehicles. In order to meet the requirements of the running mileage of the electric vehicle and reaches a predetermined voltage and capacity, the need for a plurality of lithium ion battery series-parallel, compose a power battery module.
[5]
In the related technology, some of the battery module is a plate or the upper and lower supporting frame type for the grouping mode, but interchangeability and versatility is poor; some through the screw and connecting piece and a battery are connected together, the joint is easy to cause the temperature raised problem; there are also made of steel plate structure, this makes the weight of the die set is too large, and the bad heat dissipation performance, module performance is not good, there are improved space.
