Abstract

The invention provides a battery pack with waterproof performance. Tight connection of a box and a box cover is achieved via cooperation of a clamping piece and a first bump, and meanwhile rubber sheets are arranged on the cooperating surfaces, so that sealing between the box and the box cover is achieved, and moisture and water vapor are prevented from entering; the box cover is pressurized by adjusting the bolt; sealing effect is further improved via cooperation between a sealing piece and a first connector, so that the battery pack has good waterproof performance; disconnection between an electrode connector and a battery is achieved due to the use of a water sensitive sensor, so that security is ensured; battery cell support units are combined according to actual situations, and replacement efficiency of battery cells is improved; compared with an integrated multi parallel battery cell supports, the battery pack with waterproof performance is simple in structure and reduced in cost; meanwhile, each battery cell is separated from another one by using the battery cell support unit, a short circuit risk caused by broken skin of the battery cells is avoided, a liquid cooling box is placed in a cavity between a clamping groove and a bottom frame, so that space is saved, heat is taken away and thus temperature in the shell is reduced.

Description

technical field

[0001] The invention relates to the technical field of batteries, in particular to a battery pack with waterproof performance. Background technique

[0002] Battery packs used in humid or watery environments have waterproof requirements, so the battery pack needs to be installed in a closed space, but during the use of the battery pack, the battery pack will continue to generate heat, and the temperature will accumulate After a certain time, it will affect the performance of the battery pack, thereby affecting the service life of the entire battery pack, which will increase the cost to a certain extent. The usual air-cooling technology generally needs to be carried out in an open environment, so the air-cooling technology is not suitable for battery packs used in such environments. With the rise of new energy battery packs such as nickel-metal hydride power battery packs, liquid cooling technology has diversified technologies. How to design a battery pack th...
