Face and top surface.
This power battery module structure, the both sides up and down of the end plate are equipped with to the curved bending part of battery pack side, described
Bending part is equipped with the first mounting hole, and the both ends of PTC heating plates are equipped with the second mounting hole, and the first mounting hole leads to the second mounting hole
Connector is crossed to fix.
After adopting the above technical scheme, the present invention has the advantages that compared with prior art：
By the way that battery core is arranged in supporting item, a supporting item both sides can install battery core, so that battery core is tight
Solid matter arranges, volume smaller, and intensity is high, connects by using the rigid member that battery is heated or cooled and the end plate at battery pack both ends
Connect, form a rigidity entirety, PTC heating plates or coldplate are integrated into battery modules, substitute percentage of batteries modular structure
Part, so as to avoid soft-package battery structural strength low, while also so that battery module structure intensity greatly improves, it is not necessary to volume
Outer structural member, disclosure satisfy that the structural strength of battery modules.
