Description
Technical field
The utility model relates to a kind of lug syndeton of lithium ion battery group, is specially adapted to the connection of lithium ion soft-package battery group.
Background technology
Lithium ion battery is a kind of novel energy, beginning is used in the industry-by-industry widely in market at present, continual renovation along with the lithium-ion electric pool technology, product increasingly mature, reduction on the cost and the optimization on the performance, lithium ion soft-package battery ratio in market occupies more and more to be come greatly, because the pollution of lead-acid battery and national policy be to the more supports of lithium ion battery, originally much lead-acid batteries are substituted by lithium ion battery.
Because being extensive use of of Soft Roll lithium ion battery, the thing followed is, the accident that lithium ion battery causes emerges in an endless stream equally, part partly cause is that the quality problems of lithium ion battery own cause, but reason is because the connectivity problem between the inside battery causes greatly simultaneously, and the problem on inner the connection is avoidable fully.
Simultaneously, reprocess in the maintenance process in the lithium ion battery group, often because battery pack is not easy dismounting after welding, one or many damages of monomer cause whole Battery pack to be scrapped, and have increased the loss of cost in the industry.
The utility model content
For the fail safe that guarantees that better battery pack connects, avoid the unnecessary accident of lithium ion battery to take place, and improve the serviceability of lithium ion battery group better, improve the reliability that the lithium ion battery group connects, the utility model provides a kind of lug syndeton of lithium ion battery group in order to realize above purpose.
The utility model adopts following technical scheme to realize: a kind of lug syndeton of lithium ion battery group, and described cell is fixed into battery pack according to mode in parallel or series connection, and its lug is towards a side setting; Lug one side of described battery pack is provided with connecting plate with the lug electrical connection of each cell, between connecting plate and described battery pack, be provided with insulating trip, be provided with the slot realization location that is complementary with described battery pack lug position and size at described insulating trip and connecting plate, described connecting plate is electrically connected with lead.
In the utility model, described connecting plate is the printed circuit board (PCB) of double-sided copper-clad.
In the utility model, the lug of described cell is connected by soldering with the pad of described printed circuit board (PCB).
In the utility model, described connecting plate is at least two.
In the utility model, the slot of described connecting plate is at least two.
In the utility model, described lead is electrically connected with terminal.
When battery is assembled, requirement refills connecting plate after loading onto insulating trip, be for the aluminum plastic film edge sealing top that prevents cell charged, if charged edge sealing top directly contacts with connecting plate, the battery pack micro-short circuit may be caused, of long duration the lithium ion battery fault will be caused.Connecting plate can be connected in battery pack and be connected in parallel, and connected mode can be carried out conversion according to connecting needs, forms the different model battery pack.When adopting the polylith connecting plate that the soft-package battery group is connected, can carry out multiple arranging, the connecting plate slot can connect more flexible for two grooves, three-flute, four grooves etc.Connecting plate is the single module type assembling in the cell connection procedure, does not have structural interference during other is connected with battery, has prevented the short circuit that the battery pole ear collision causes effectively.
From the above mentioned, the utlity model has following beneficial effect:
1, cell can carry out multiple connection and arranges, and flexibility is strong;
2, solve lithium ion battery owing to connect the short circuit phenomenon that causes, improved the security performance of entire cell;
3, connecting plate is easy to process, can produce in batches, and cost is low;
4, the battery pack that adopts the utility model to connect can be carried out heavy-current discharge, has avoided electric current excessive and the short circuit that causes and bad phenomenon in use;
5, convenient welding after battery pack sequences, directly is welded on the lug bending on the connecting plate corresponding bonding pad;
6, the damage of cell has convertibility in the battery pack.
