Problems solved by technology

[0002] In our daily life, electric vehicles are used as daily means of transportation, and the internal battery provides the main power for the form. If an emergency occurs during the form of the electric vehicle and the electric vehicle is hit, the battery will be severely damaged A large impact will cause damage to the internal structure. In severe cases, it will cause an internal short circuit and heat to cause the battery to burn. In addition, if a fire occurs inside the home, the battery of the electric vehicle will also promote the spread of the fire, causing unnecessary human and financial losses. A battery protection device for electric vehicles described in the present invention can solve the above problems

Abstract

A battery protection device for an electric vehicle disclosed in the present invention comprises a main body of the protection device, a first protection cavity is arranged inside the main body of the protection device, and an elastic lifting plate with a certain elasticity is fixed on the lower wall of the first protection cavity , the present invention reduces the impact force received by the battery pack during the collision process through multi-point shock absorption when the device shell is hit by the shock absorbing device of the array, protects the integrity of the battery pack, and when the device is hit, it will The output power of the battery pack is cut off, and when the protection device is damaged due to a large impact force, the carbon dioxide gas stored inside the device is used to reduce the possibility of burning at the crushing impact at the first time, and the carbon dioxide gas stored in the device is discharged by triggering the impact. A fire protection wall is formed around the battery to further protect the integrity of the battery pack.

Description

Technical field [0001] The present invention relates to the field of battery, in particular an electric vehicle battery protection device. Background technique [0002] In our daily lives, the electric vehicle serves as a daily vehicle, and the internal battery provides the main driving force in the form of the electric vehicle, and when an emergency occurs during the form of an electric vehicle, the battery will be compared. Large impact, resulting in internal structural damage, will cause internal short circuit and heat generation to cause battery burning, and if the fire is in the family, the electric vehicle battery will also contribute to the spread of the fire, bringing unnecessary people to lose, A electric vehicle battery protection device, which is described in the present invention, can solve the above problems. Inventive content [0003] In order to solve the above problem, this example is designed with an electric vehicle battery protection device. In this case, an e...
