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.
