Battery pack protection device for new energy automobile and new energy automobile battery

Abstract

The invention discloses a battery pack protection device for a new energy automobile and a new energy automobile battery. The device comprises a protection device body, a supporting frame and an upper cover, an air inlet pipe is fixedly connected to the bottom end of the outer wall of one side of the protection device body, and an air filtering pipe is detachably connected to the end, away from the protection device body, of the air inlet pipe; the bottom end of the outer wall of one side of the protection device body is fixedly connected with an exhaust pipe. Heat can be transmitted to cooling liquid in the heat dissipation plate through the heat dissipation plate, temperature emitted by the battery pack can be transmitted to the upper cover along with air and then transmitted to the mounting plate through the heat conduction plate, heat on the mounting plate can be absorbed by the heat conduction rods, and then the heat is dissipated to external air through the heat dissipation rods on the heat conduction rods. And external cooling air can be guided into the protection device body through the air filtering pipe, so that the battery pack in the protection device body is cooled.

Description

Technical field[0001]The present invention relates to the technical field of new energy vehicle battery packs, in particular a new energy vehicle battery pack guard and a new energy vehicle battery.Background technique[0002]The composition of the new energy vehicle includes: electric drive and control system, driving force transmission and other mechanical systems, the work devices such as the established task, the power driver and control system are the core of electric vehicles, but also the largest difference between the internal combustion engine car, electricity The driving and control system consists of a speed control device such as a motor, a power supply, and a motor, and other devices of the electric vehicle are basically the same as the internal combustion engine, the main driving force of the new energy vehicle is the battery pack, so the safety use of the power battery pack is very important. of.[0003]However, when the existing battery pack is not stopped, a certain amo...

Problems solved by technology

[0003] However, when the existing battery pack is used continuously, it will emit a certain amount of heat. When the heat is accumulated together and cannot be dissipated, the temperature of the battery pack body will be too high, which will cause the battery pack to age and reduce the battery life. service life, and when the temperature is too high, the battery pack will burn, which will cause certain hidden dangers to people's life safety
