Negative bracket) design, when the cylindrical cell in battery modules middle position of the invention needs to repair dismounting, only need
The elastic force of the cathode connection elastic slice is overcome by external force, it is the battery core singly gone here and there that dismounting, which can be completed, certainly to cylindrical cell
Body has no any damage, easy to disassemble；Meanwhile compared to traditional mode that cylindrical cell both ends are carried out with electric resistance welding, originally
In structure and packaging technology, the cylindrical cell in each layer of battery core combination eliminates resistance welding when installing, right for invention
For manufacturer, the investment of the equipment and cost of labor in producing line is largely reduced, reduces production cost.
2, cathode connection elastic slice can both realize fixed battery in it, while in battery charge and discharge process, not only bottom is connect
Electric shock pond, the elastic slice of side can also play shunting function, to reduce the connection internal resistance between multiple cylindrical cells, make battery core
Series-parallel connector is higher by the ability of electric current, more conducively the quick charge of integral battery mould group and high power discharge.
3, the design of intermediate support through-hole is calculated by size, it is ensured that the company of cathode connection elastic slice and cylindrical cell
It connects close.The height of the intermediate support simultaneously guarantees the fixed stability of cylindrical cell.
Therefore, in conclusion compared with prior art, the present invention provides a kind of cylindrical cell battery modules,
It can guarantee that the battery modules being made of multiple cylinder type lithium ion battery cells not only connect reliably, but also can substantially reduce
Because resistance welding and caused by damage to battery battery core, improve the quality of production of battery modules, be capable of forming the rule of industry
Modelling is conducive to widely apply, be of great practical significance.
The above is only a preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, various improvements and modifications may be made without departing from the principle of the present invention, these improvements and modifications are also answered
It is considered as protection scope of the present invention.
