The invention provides the folded type busbar for large-power application of the battery pack, and elastic connection of pole rods is achieved.
Description
Technical field
The present invention relates to a kind of bus-bar, be specifically related to a kind of folded form bus-bar supporting power brick high-power applications.
Background technology
In large-scale energy-storage system, cell needs to realize the capacity of energy-storage system and the expansion of power characteristic by parallel connection, in order to support the application of big current, just needs to carry out bus-bar and connect between the pole of therefore cell.Because battery has deformation when charge and discharge point, just need to be connected with elasticity between each pole, avoid the stress between battery with bus-bar to shine into the damage of battery electrode column, and existing bus-bar does not also possess such characteristic.
Summary of the invention
In order to solve the problems of the technologies described above, the invention provides a kind of bus-bar supporting power brick high-power applications, the elasticity achieved between each pole connects.
In order to achieve the above object, the technical solution adopted in the present invention is:
A kind of folded form bus-bar supporting power brick high-power applications, comprise main conducting strip, described main conducting strip is folded into wavy shaped configuration, the main conducting strip side relative with waveform is connected with some branch road conducting strips, each branch road conducting strip is provided with one in order to connect the binding post of battery electrode.
The connected main conducting strip side of described branch road conducting strip is vertical.
All branch road conducting strips are connected with the same side of main conducting strip.
The waveform of described wavy shaped configuration is square wave.
The material of described main conducting strip and branch road conducting strip is copper.
Described main conducting strip and branch road conducting strip integrally casting shaping.
The beneficial effect that the present invention reaches: main conducting strip of the present invention is folded into wavy shaped configuration, can adjust the rigidity connected, and the elasticity that can realize between each pole connects, and decreases the demand to horizontal space, be beneficial to heat radiation while not reducing conveyance capacity.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is longitudinal sectional drawing of the present invention.
Fig. 3 is the structural representation that the present invention is connected with battery.
Fig. 4 is the structural representation of connecting after realizing many cell parallels.
Embodiment
Below in conjunction with accompanying drawing, the invention will be further described.Following examples only for technical scheme of the present invention is clearly described, and can not limit the scope of the invention with this.
As illustrated in fig. 1 and 2, a kind of folded form bus-bar supporting power brick high-power applications, comprise main conducting strip 1, main conducting strip 1 is folded into wavy shaped configuration, the waveform of wavy shaped configuration is square wave, main conducting strip 1 side relative with waveform is connected with some branch road conducting strips 2, connected main conducting strip 1 side of branch road conducting strip 2 is vertical, all branch road conducting strips 2 are connected with the same side of main conducting strip 1, each branch road conducting strip 2 are provided with one in order to connect the binding post 3 of battery electrode.
The material of above-mentioned main conducting strip 1 and branch road conducting strip 2 is copper, main conducting strip 1 and branch road conducting strip 2 integrally casting shaping.
The above-mentioned folded form bus-bar holding power brick high-power applications and the structure chart of battery electrode are as shown in Figure 3, battery one and battery two are connected from different binding posts 3 respectively, the parallel connection of both realizations, the main conducting strip 1 of wavy shaped configuration, the demand to horizontal space is decreased while not reducing conveyance capacity, be beneficial to heat radiation again simultaneously, also can adjust the rigidity of connection simultaneously.
The above-mentioned folded form bus-bar holding power brick high-power applications also can further improve, connect after realizing many cell parallels, concrete structure as shown in Figure 4, as long as all arrange branch road conducting strip 2 in main conducting strip 1 both sides relative with waveform, in figure, battery one, battery two, battery three and battery four are connected different binding posts 3 respectively, battery one and battery two parallel connection can be realized, battery three and battery four parallel connection, two parts series connection simultaneously.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the technology of the present invention principle; can also make some improvement and distortion, these improve and distortion also should be considered as protection scope of the present invention.
