Embodiment 1

[0023] Such as figure 1 , figure 2 As shown, the special lithium battery charging explosion-proof box provided in this embodiment is a lithium battery charging explosion-proof box for electric bicycles, including a box body 1, a box cover 2, a charging connector 3, a smoke detector 4 and a fire extinguishing pipe 5.

[0024] Wherein, box cover 2 is arranged on the top of box body 1 and cooperates with box body 1, and box cover 2 is hinged with box body 1, and handle 6 is set on box cover 2 outsides, is convenient to open or close. A locking part 7 is provided on the outer side of the extension of the case cover 2, and a locking part 8 is provided in the middle part of the side wall of the box body 1. locking.

[0025] A through hole is provided on the side wall of the box body 1 through its thickness, and the charging connector 3 is inserted in the through hole, which is equivalent to a charging adapter. The two ends of the charging connector 3 are respectively located ins...

Embodiment 2

[0032] The special lithium battery charging explosion-proof box provided in this embodiment is the same as the structure provided in Example 1, the difference is that the fire extinguishing agent in this embodiment is a liquid fire extinguishing agent (water-type fire extinguishing agent), once the lithium battery in the box burns , the fire extinguishing pipe will rupture, and the internal liquid overflows to extinguish the burning lithium battery, avoiding the explosion accident.

Embodiment 3

[0034] In this embodiment, the material of the box body and the box cover is Q235 carbon steel, which has high strength and can effectively avoid flame extension. The box is lined with fire-resistant board, which strengthens the isolation and fireproof performance of the special lithium battery charging explosion-proof box.

Abstract

The invention discloses a specialized lithium battery charging explosion-proof box, and the box comprises a box body, a box cover, a charging connector, a smoke sensing alarm and a fire extinguishingtube. A lithium battery is placed in the box body and the box body is covered with the box cover, thus, the lithium battery is isolated from the outside, and harm to the lithium battery caused by an outside environment, particularly an outside fire source, is avoided. Meanwhile, a function of charging and protecting the lithium battery is realized, the lithium battery is prevented from generatingaccidents of burning and explosion in a charging process. With the smoke sensing alarm, when smoke concentration in the box body is relatively high, the smoke sending alarm can give an alarm for reminding, fire disaster can be avoided, and usage can be safe. With the fire extinguishing tube, and fire extinguishing agent set in the fire extinguishing tube, when the lithium battery in the box body burns, the fire extinguishing tube fractures in case of fire flame, the fire extinguishing agent overflows, a fire extinguishing effect is realized, generation of the explosion accident is prevented effectively, and safety is high.

Description

technical field [0001] The invention relates to the technical field of battery protection devices for electric vehicles, in particular to a special lithium battery charging explosion-proof box. Background technique [0002] Lithium batteries are generally divided into lithium metal batteries and lithium ion batteries. Among them, lithium ion batteries are rechargeable and have high energy density, and their applications are becoming more and more extensive. The electrolyte inside the lithium-ion battery is a flammable liquid, and the electrode is a flammable material. The lithium-ion battery is thermally out of control when it is overcharged, short-circuited, overheated, punctured or collided, and it is easy to catch fire or even explode. Therefore, the safety of lithium-ion batteries It is the bottleneck that inhibits the development of lithium-ion batteries and related industries (such as new energy vehicles). [0003] At present, the power supply batteries of electric ve...
