The connection structure can realize tighter and firmer connection between the anodes and the cathodes of the battery packs, thereby saving the space, greatly reducing the impact of battery pack vibrations on the battery pack connection, and further completely solving the problem of reliability of tandem and multipled battery packs. The utility model can be widely applied in lithium ion battery packs in electricvehicles and electric tools, so that the reasonable and perfect structural design can greatly improve the volume ratio capacity of the battery packs and prolong the service life of batteries.
Description
Technical field
The utility model relates to a kind of battery pack syndeton, especially a kind of many strings and round lithium ion battery group syndeton.
Background technology
Because lithium ion battery has the voltage height, capacity is big, volume is little, light weight, advantages such as operating temperature range is wide, the lithium ion battery group has been widely used in every field, especially be applied to fields such as motor vehicle, electric tool, battery pack such as motor vehicle, electric tool environment for use harshness is had relatively high expectations to aspects such as fail safe, stability, mechanicalnesses.At present, be applied to connected mode that the lithium ion battery group connection in series-parallel of electric automobile adopts for being threaded or welding, these two kinds of connected modes all need to take certain space, and it is unreliable to connect, cause battery pack in use because environments for use such as vibration cause connecting loosening, the contact resistance difference of battery pack is increased, and then reduce the consistency of battery in the battery pack, influence the useful life of battery pack.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of many strings and round lithium ion battery group syndeton, described syndeton can solve fundamentally owing to going here and there also syndeton influences the battery pack problem in useful life more, and process and assemble is convenient, appearance looks elegant, usage range is wide, highly versatile.
For solving the problems of the technologies described above, the technical solution of the utility model is:
A kind of many strings and round lithium ion battery group syndeton, the round electric core sequence arrangement of round lithium ion battery group in parallel, battery anode posts insulating washer, and battery anode is the conflux anodal Welding Structure of motherboard of positive pole, and the battery pack negative pole is the conflux negative pole Welding Structure of motherboard of negative pole; Aforementioned battery pack both positive and negative polarity successively closely connects.
Preferably, above-mentioned many strings and round lithium ion battery group syndetons, wherein negative pole confluxes has the connection boss on the motherboard.
The beneficial effects of the utility model are:
Above-mentioned many strings and round lithium ion battery group syndeton, both positive and negative polarity connects close and firm more between the battery pack, save the space, greatly reduced the impact that the battery pack vibration connects battery pack, and then thoroughly solved battery pack connection in series-parallel reliability problems, can be widely used in lithium-ion electric motor vehicle and the power tool battery group, because the reasonability and the perfection of structural design, significantly improve the volumetric specific energy of battery pack, prolonged battery useful life.

Embodiment
For further specifying the utility model, existing conjunction with figs. is described in detail:
As Fig. 1, Fig. 2 Fig. 3 and shown in Figure 4, described many strings and round lithium ion battery group syndeton, round electric core 3 sequence arrangement of round lithium ion battery group in parallel, battery anode posts insulating washer 2, battery anode is the conflux anodal Welding Structure 5 of motherboard 1 of positive pole, the battery pack negative pole is the conflux negative pole Welding Structure 6 of motherboard 4 of negative pole, wherein negative pole confluxes the boss 7 of connection on the motherboard, the distributing position that wherein connects boss 7 is anodal corresponding with the round lithium ion battery group of another parallel connection that is connected with it, thereby with the tight button and being connected of both positive and negative polarity successively between each battery pack.
Specification:
1, conflux motherboard 1 of positive pole adopts flat type, and anodal Welding Structure 5 is made in each battery anode position, improves welding procedure; Insulating washer 2 is attached to side of the positive electrode, short circuit when preventing that round electric core 3 both positive and negative polarities from confluxing motherboard 1 by positive pole; The negative pole motherboard 4 that confluxes is provided with and connects boss 7, make that both positive and negative polarity connects close and firm more between the battery pack, save the space, thereby solved in the background technology the many strings of round lithium ion battery and between connector occupy certain space, and connect insecure problem, greatly reduce the impact that the battery pack vibration connects battery pack, and then thoroughly solved battery pack connection in series-parallel reliability problems; Negative pole Welding Structure 6 is made in each battery pack negative pole position, improves the manufacturability of welding.
2, after the series connection of each battery pack that is formed in parallel, compress the purpose that first segment and final section battery pack reach series connection by applying reliable external force.
The above only is a preferred implementation of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection range of the present utility model.
