How to apply an insulating layer to a car battery cell

摘要

Due to the dynamic mechanical loads subjected to the motor vehicle drive battery, it is advantageous that the housing of the battery cell of the drive battery is at least partially covered with an electrically insulating layer made of a coating material. A method for this purpose and a coating station for carrying out the method have been proposed. This method transitions to a liquid electrically insulating coating material 100, which is applied by a coating applicator 20 as individual droplets 102 that are individually separated and produced. The droplets form coating dots 104 on the outer surfaces 210A, 210B, 210C of the housing 204 , and the coating dots are sequentially applied adjacent to or overlapping each other by a coating applicator 20 so that the coating The dots together form the coating line 106 .
