ABSTRACT:
In high-temperature batteries which contain a series circuit of galvanic cells with a solid electrolyte, the solid electrolyte can be damaged without the damage being noticed when the battery is short circuited in the cold condition and a voltage reversal occurs at individual cells. According to the invention, a protection device is formed of elements that are connected in parallel with the cells. The elements have a high resistance at the operating temperature of the battery and a low resistance in the cold condition. The elements form a voltage divider in the case of a short circuit caused at external terminals of a cold battery. The voltage divider ensures the desired voltage division.
