Abstract

Due to the dynamic mechanical loads to which motor vehicle traction batteries are subjected, housings of battery cells of the traction batteries are covered at least in part by an electrically insulating layer made from a coating material. For this purpose, a method and a coating station for carrying out the method are proposed. The method is performed with a liquid electrically insulating coating material, by applying separately produced individual drops of the coating material using a coating applicator. The drops form coating points on an outer surface of the housing, which coating points are applied sequentially with the coating applicator, adjacently to one another or overlapping, so that together they form coating lines.
