Two interfaces 32, the other end connect total negative terminal 416.It should be noted that total negative wire beam is taken again after being clamped by card line seat 2353
Enter total negative terminal 416, it is more stable that so total negative wire beam connects total negative terminal 416 after 2353 load-bearing of card line seat.Total positive harness
Total voltage with total negative wire beam for battery pack described in connecting detection.The second interface of electronic tag harness one end connection BMS3
32, the other end connects electronic tag 417.
The parameter of the battery pack is as follows:
When battery pack needs to extend, as shown in figure 12, the fixation seat assembly of battery pack described in every two is closely arranged relatively
A pair of of battery pack is formed, multipair battery pack is successively closely aligned, and all battery packs are sequentially connected in series.Fixed seat assembly is located at case-side
Face does not interfere compact Layout, and is in a horizontal state, and does not retain water droplet.It is fixedly connected with adjacent battery pack by fixed bandage 53,
Fixed bandage 53 be it is detachable, facilitate the assembly for realizing battery pack using fixed bandage 53.Total battery pack after the extension
Anode 51 and cathode 52 be located at middle part, i.e., vehicle or external equipment connect total battery pack by anode 51 and cathode 52.Always just
Pole 415 and total negative terminal 416 are respectively the conical surface and cylinder, it can be achieved that rapid identification and connection, connect high efficient and reliable.
Be it is necessary to described herein finally: above embodiments are served only for making technical solution of the present invention further detailed
Ground explanation, should not be understood as limiting the scope of the invention, those skilled in the art's above content according to the present invention
The some nonessential modifications and adaptations made all belong to the scope of protection of the present invention.
