Embodiment 1

[0027] Please refer to figure 1 , FIG. 2(A)-(D), the assembly device of the rechargeable battery pack includes a circuit board 30, and the circuit board 30 includes a parallel circuit 10 and a series circuit 20. The parallel circuit 10 includes a plurality of parallel negative contacts 11 sequentially arranged on the circuit board 30, a parallel negative input 12, a first line 16 connecting the plurality of parallel negative contacts 11 and the parallel negative input 12, and a first insulation covering the first line 16. Layer 31, a plurality of parallel positive contacts 14 interlaced with the plurality of parallel negative contacts 11, a parallel positive input 15, a second circuit 13 connecting the plurality of parallel positive contacts 14 and the parallel positive input 15, and a second insulation covering the second circuit 13 Layer 33. The series loop 20 includes a plurality of series positive contacts 21 sequentially arranged on the circuit board 30 , a plurality of ...

Embodiment 2

[0040] Please refer to Figure 6 , the circuit board 30 is provided with a parallel circuit 10 and a series circuit 20 opposite to each other. The parallel positive contact 11 and the parallel negative contact 14, the series positive contact 21 and the series negative contact 22 are respectively arranged on both sides of the circuit board 30, so that it can be simultaneously The two groups of batteries of the rechargeable battery 40 and the rechargeable battery 400 are charged in parallel or discharged in series, which increases the number of accessible rechargeable batteries and increases the capacity of the rechargeable batteries.

Embodiment 3

[0042] Please refer to figure 1 , 7 and 8, two independent parallel circuits 10 and 100 are arranged on the circuit board 30 . In the parallel circuit 10, the parallel positive contacts 14 and the parallel negative contacts 11 are arranged on one side of the circuit board 30; In addition, the parallel negative input 12 , 102 and the parallel positive input 15 , 105 of the two parallel circuits 10 , 100 are arranged at the same end of the circuit board 30 . At this time, if Figure 7 As shown, in this embodiment, a single charging module 50 can be used to charge the rechargeable battery 40 and the rechargeable battery 400 simultaneously by using the parallel circuit 10 and the parallel circuit 100 respectively.

Abstract

The invention relates to an assembly device of a rechargeable battery pack, which comprises a circuit board, at least one parallel loop and at least one series loop, wherein the at least one parallel loop and the at least one series loop are integrated on the circuit board and mutually insulated. The assembly device of the rechargeable battery pack integrates the original loops which need to be connected in series and in parallel together through the circuit board, thereby avoiding the inconvenient use caused by series connection and parallel connection of the batteries. When the charging needs to be carried out, only a positive pole and a negative pole of a rechargeable battery need to be led out and well arranged according to the design sequence to connect the rechargeable battery with the parallel loop or the series loop, thereby realizing the functions of charging and discharging. The assembly device can simplify the application of the rechargeable battery to the application of a dry battery, reduce the using cost of the rechargeable battery and improve the performances of the rechargeable battery. Furthermore, if failure and other faults occur during the use of the rechargeable battery, the whole battery pack does not need to be abandoned, and only the battery with the fault needs to be replaced, thereby leading the rechargeable battery to be more flexible and convenient to assemble during the application.

Description

【Technical field】 [0001] The invention relates to an assembly device of a rechargeable battery pack. 【Background technique】 [0002] As oil stocks become less and less, people's desire for electric motorcycles and electric vehicles is increasing day by day, and batteries that act as the power source of electric motorcycles and electric vehicles are getting more and more attention. These batteries are mainly rechargeable batteries (secondary batteries), and tend to use high-performance batteries such as nickel-metal hydride batteries, lithium-ion batteries, and lithium-ion polymer batteries. However, because rechargeable batteries generally require multiple batteries to be used in series or in parallel. The traditional method is to first connect the batteries in series or in parallel to form a battery pack, and then design a circuit or power management system to control the charging and discharging of the battery pack. In this way, the structure of the battery pack is compl...
