Problems solved by technology

[0003] At present, the power device on electric new energy vehicles is usually a battery pack, and the efficiency of the battery pack in cold weather will be greatly reduced, so that the cruising range of new energy vehicles will be greatly reduced, and the existing new energy vehicle battery pack Usually fixed inside the car body, its shock absorption effect is poor, and it is easy to damage and leak electricity when it is hit by a collision. In order to solve the above problems, we propose a battery protection device that improves the mileage of new energy vehicles in winter.

Abstract

The invention provides a battery protection device for increasing the running endurance mileage of a new energy automobile in winter, the battery protection device for increasing the running endurance mileage of the new energy automobile in winter comprises a heating assembly, and a T-shaped rod is arranged in the heating assembly. According to the battery protection device for improving the winter driving endurance mileage of the new energy automobile, a new energy battery can extrude a pressure reduction piece when being subjected to vertical vibration force, and a pressure reduction spring can effectively offset part of pressure reduction force, so that the damping effect of a battery pack is effectively improved, and the battery pack is prevented from being damaged and leaking electricity during collision; and the safety performance of the vehicle is improved. When the vehicle is started, the transmission gear drives the driven gear to rotate, the hollow block is further made to move up and down periodically, gas in the gas inlet cavity can be heated, the heated gas can preheat the battery pack, and therefore the effects that the battery pack is effectively preheated, the use efficiency of the battery is improved, and the endurance mileage of the new energy vehicle in cold weather is increased are achieved.
