Abstract

A new energy automobile battery damping and cooling device and a battery temperature adjusting device belong to the field of new energy automobiles. The damping and cooling device comprises a sealed cooling liquid tank, a cooling pipeline connected with an inlet and an outlet of the cooling liquid tank, and a radiator connected to the cooling pipeline. A battery is arranged in the sealed cooling liquid tank. A partition plate is arranged in the cooling liquid tank in a sealing manner, and the partition plate is connected with the battery in a sealing manner and moves along with the battery. The partition plate is connected with one-way valves communicating the cooling liquid on the two sides of the partition plate and pressure release valves. Elastic connecting pieces are arranged betweenthe two ends of the battery along the liquid flowing direction and the cooling liquid tank. In the running process of an automobile, the battery vibrates and extrudes the cooling liquid in the coolingliquid tank to flow in one direction, the cooling liquid circulates along the cooling pipeline, and the cooling liquid flows back into the cooling liquid tank after being cooled by the radiator. Thebattery can be automatically damped and cooled in the running process of the automobile, and therefore, the service life of the battery is prolonged.
