Abstract

According to the new energy automobile battery box integrated forming low-pressure casting method and the assembling method, a new energy automobile battery box body is integrally formed through a low-pressure casting process, the production output is effectively improved, and the manufacturing and production cost is greatly saved. The FDS technology is used in cooperation of the water cooling plate and the battery box body, 26 mm PU foam is sprayed on the periphery of the battery box body, the use performance of a new energy battery at low temperature is effectively improved, and the service life of the new energy battery is prolonged.

Description

technical field [0001] The invention relates to the field of new energy automobile battery case casting, in particular to a new energy automobile battery case integrated low-pressure casting method and assembly method. Background technique [0002] The box structure of the traditional new energy vehicle battery box is welded, and the cooperation between the water-cooled plate and the battery box box adopts rotational friction welding, which reduces the sealing of the battery box, and further cannot guarantee the temperature in the battery box, reducing the temperature of the battery box. The performance of new energy vehicles at low temperatures will seriously shorten the service life of new energy vehicle batteries. Contents of the invention [0003] The object of the present invention is to overcome the above disadvantages and provide a low-pressure casting method and an assembly method for integrally forming a battery box of a new energy vehicle. [0004] The purpose o...
