Problems solved by technology

Lithium-ion batteries will generate heat during charging and discharging. When the battery packs are connected in series and parallel, due to the small internal space of the batteries and insufficient ventilation of the box, the internal temperature of the battery will rise. Lithium-ion batteries are very sensitive to temperature, and temperature rise will affect The performance of the battery will shorten the battery life, and if the temperature is too high, it will easily cause safety hazards

Embodiment 1

[0029] Such as image 3 As shown, the battery 2 in this embodiment is a soft-packed lithium-ion battery. Put two soft-packed lithium-ion batteries into the front and rear sides of the battery frame 1. The two batteries are separated by an insulating plastic plate 11 inside the battery frame 1. The two batteries 2 The positive pole tab 21 and the negative pole tab 22 are respectively welded to the positive pole current collecting column 12 and the negative pole current collecting pole 13 to form a battery board.

[0030] Such as Figure 7As shown, three battery boards are connected through buckles 17 and slots 18 to obtain a battery pack, and then the connected battery pack is connected to the battery case 5 . Place the current collecting plate 3 on the positive electrode current collecting column 12 and the negative electrode current collecting column 13, then place the lead plate 4 in the groove 32 of the current collecting plate 3, and fix the current collecting plate 3 and...

Embodiment 2

[0033] The battery assembly process is the same as that in Embodiment 1, except that a heat pipe is inserted into the heat pipe channel 16 of the assembled battery module, which can be used for heat dissipation of the battery.

Embodiment 3

[0035] Such as Figure 8 As shown, the battery assembly process is the same as that in Embodiment 1, except that the three parallel-connected battery plates are connected in series by using the current collector plate 3 for series connection, thereby assembling a three-parallel-three-series battery module.

Abstract

The invention discloses a lithium-ion battery pack assembly module, which comprises a battery frame, a current collecting plate and an insulating cover. There are positive current collecting post and negative current collecting post, both of which are provided with threaded holes, the bottom of the battery frame is provided with a base, and the base is provided with bolt through holes, and the current collecting plate is set on the positive current collecting post. Above the current collecting post and the negative current collecting post, there is an insulating cover slot in the middle of the top of the battery frame, and an insulating cover is provided above the current collecting plates corresponding to the positive and negative current collecting posts, and the insulating cover is fixed on the insulating cover. On the cover slot, a heat pipe channel is arranged on the insulation cover slot. The invention can realize the protection of the lithium-ion battery, conveniently realize the series-parallel connection of the battery, and can also eliminate the heat generated during the charging and discharging process of the battery.
