Abstract

The invention discloses a protective shell for a battery pack, relates to the technical field of battery packs, and aims at solving problems that an existing battery pack shell is inconvenient to assemble and disassemble and relatively low in protective safety. The protective shell comprises a lower shell body and an upper shell body, a plurality of mounting grooves are formed in the inner side of the lower shell body, battery packs are arranged in the mounting grooves, cooling water pipe sets are arranged in the lower shell body, a water inlet is formed in the rear end of the lower shell body, and a water outlet is formed in the front end of the lower shell body. Explosion-proof mechanisms are arranged on the two sides of the upper end of the upper shell, a lower convex edge is arranged at the upper end of the lower shell, a plurality of limiting grooves are formed in the upper end of the lower convex edge, an upper convex edge is arranged at the lower end of the upper shell, a plurality of limiting columns are arranged at the lower end of the upper convex edge, and the limiting columns are embedded into the limiting grooves.

Description

technical field [0001] The invention relates to the technical field of battery packs, in particular to a protective shell for battery packs. Background technique [0002] The battery pack is an important component of new energy vehicles, which directly affects the performance of new energy vehicles. It can be said that in a pure electric vehicle, the battery is its heart. Similarly, in a hybrid vehicle, the battery can also be regarded as another a heart. The battery is externally charged through the power plug, supplies power to the motor, drives the vehicle, and stores the energy recovered by braking. In automotive applications, many independent electrochemical units are connected in series to form a battery pack, that is, a battery pack and a battery pack shell. As the carrier of the battery module, it plays a key role in the safe operation and protection of the battery module. [0003] However, the existing battery pack casing is inconvenient to assemble and disassembl...
