A battery protection device for a new energy vehicle, which has good safety performance

Abstract

The invention discloses a new energy vehicle battery protection device with good safety performance, which includes a box, A mounting groove is arranged inside the housing of the box body, and a stable keel is inserted into the mounting groove, The bottom of the outer wall of one side of the box body is connected with a connecting hinge through bolts, the box body is connected with a box cover through the connecting hinge, and the outer wall of one side of the box cover is bonded with a sealing ring, the inner wall of the box body is sleeved with a flame retardant shell, and the inner wall ofthe flame retardant shell is bonded with a moisture absorbing pad, and the inner wall of the bottom of the box body is connected with a shock absorbing spring through bolts. The invention can preventthe battery body from being collided or squeezed inside the box body to cause deformation, The safety of the device is effectively improved. The heat generated by the battery body can be dissipated intime by the heat conduction column and the heat dissipation plate, the fire of the battery body inside the box body can be avoided, and the shock absorbing spring can prevent the battery body from shaking violently, thus providing good protection for the battery body.

Description

Technical field [0001] The invention relates to the technical field of new energy vehicles, in particular to a new energy vehicle battery protection device with good safety performance. Background technique [0002] New energy vehicles refer to the use of unconventional vehicle fuels as the power source (or the use of conventional vehicle fuels, the use of new on-board power devices), the integration of advanced technologies in vehicle power control and driving, and the formation of advanced technical principles and New technology and new structure vehicles. New energy vehicles include pure electric vehicles, extended-range electric vehicles, hybrid vehicles, fuel cell electric vehicles, hydrogen engine vehicles, and other new energy vehicles. Pure electric vehicles are a kind of A car with energy storage power source, which uses a battery as the energy storage power source, provides electric energy to the electric motor through the battery, drives the electric motor to run, ther...

AI Technical Summary

Problems solved by technology

The fuel used by the general engine is diesel or gasoline, and the fuel used by the hydrogen engine is gaseous hydrogen. The current electric vehicle cannot provide good protection for the battery when the battery is installed, and the safety of the battery directly affects the overall performance of the electric vehicle.
