Protection device for an electrochemical battery recharging multiple.

Protection system for multiple rechargeable battery. The protection system includes a sealed protective housing (54) which accepts the battery housing (12). An alteration of the shape exerts pressure on the sensor body (62) for an impermissible operating condition of the battery (10), and is part of an implantable system. At least one switching element is designed as an NC switch or adjusted. For a prohibited operating condition of the battery (10), a recharging circuit current, which is fed by a charging system is interrupted.
