Problems solved by technology

[0003] Most of the storage devices for electric vehicle battery packs proposed in the prior art have the disadvantages of poor battery protection and lack of flame retardancy. The publication number is CN111540865B, which proposes a new energy vehicle battery box. The shock mechanism and the protective airbag buffer the vibration of the battery box to improve the service life of the battery. However, this device cannot quickly dissipate heat from the heated battery. The spontaneous combustion of the battery pack poses a great potential safety hazard, and the device cannot seal the burning battery, and the burning battery pack will quickly ignite the main body of the electric vehicle, causing large economic losses and even endangering the lives of drivers and passengers. Therefore, we propose an intelligent management device for new energy vehicle battery packs

Abstract

The invention relates to the technical field of new energy automobiles, and discloses an intelligent management device for a new energy automobile battery pack. The intelligent management device comprises a rack, a closing mechanism is rotatably connected in the rack, the closing mechanism comprises a limiting base, and a driving arm is rotatably connected to the opposite side of the limiting base. The inner wall of the rack is slidably connected with a limiting plate, and the opposite side of the limiting plate is movably connected with a battery pack. According to the intelligent management device of the new energy automobile battery pack, when a left transmission rod slides along a ventilation bin, air in the right side of the ventilation bin is squeezed into the left side wall of the battery pack, when a right transmission rod slides along a right ventilation bin, the pressure intensity of the left end of the ventilation bin is reduced, and the right ventilation bin pumps out hot air on the right side wall of the battery pack; and through cooperation with ventilation grooves formed in the limiting plates, the convection speed of air on the outer wall of the battery pack is greatly increased, short circuit of connecting lines caused by overheating of the battery pack is avoided, and potential safety hazards are lower.

Description

technical field [0001] The invention relates to the technical field of new energy vehicles, in particular to an intelligent management device for battery packs of new energy vehicles. Background technique [0002] New energy vehicles include hybrid electric vehicles, pure electric vehicles, fuel cell electric vehicles, and other new energy vehicles. The drive and control system is the core of an electric vehicle, and it is also the biggest difference from an internal combustion engine vehicle. The electric drive and control system consists of a drive motor, a power supply, and a speed control device for the motor, among which the power supply is mostly composed of a large number of batteries connected in series. . [0003] Most of the storage devices for electric vehicle battery packs proposed in the prior art have the disadvantages of poor battery protection and lack of flame retardancy. The publication number is CN111540865B, which proposes a new energy vehicle battery bo...
