Heating Device for a Prismatic Battery Cell of a High-Voltage Battery of a Motor Vehicle, Battery Cell, Battery Module, High-Voltage Battery and Motor Vehicle

A heating device for a prismatic battery cell of a high-voltage battery of a motor vehicle, comprising:

• two sheet-shaped heating elements for arrangement on two opposite lateral outer sides of a cell housing of the battery cell;
• and
• two connecting elements which connect the two heating elements mechanically and electrically, for arrangement on a housing cover of the cell housing and for connecting to an energy source which makes available a heating current, wherein
• in order to energize the heating elements with the heating current, the first connecting element is electrically connected to first terminals of the two heating elements, and the second connecting element is electrically connected to second terminals of the two heating elements,
• the connecting elements are embodied flexibly, at least in certain areas, and as a result the heating elements are connected in a hinged manner, and
• the heating device is arrangeable on the cell housing by arranging the first heating element on a first lateral outer side of the cell housing, folding the second heating element, connected in a hinged manner to the first heating element via the connecting elements, over the housing cover and arranging the second heating element on a second lateral outer side.
