Abstract
A heating device for a prismatic battery cell of a high-voltage battery of a motor vehicle includes two sheet-shaped heating elements to be arranged on two opposite lateral outer sides of a cell housing of the battery cell, and two connecting elements to be arranged on a housing cover of the cell housing. The connecting elements are electrically connected to terminals of the two heating elements. The connecting elements are flexibly formed, at least in certain regions, and as a result the heating elements are connected in a hinge-like manner. The heating device can be arranged by arranging the first heating element on the first lateral outer side of the cell housing, swinging the second heating element over the housing cover, and arranging the second heating element on the second lateral outer side on the cell housing.
