Protective device for a repeatedly rechargeable electrochemical battery
First Claim
1. Protective device for a repeatedly rechargeable electrochemical battery with a battery housing, comprising a hermetically sealed protective housing, a detector element, and at least one switching element which is activatable by the detector element and which prevents at least one of recharging and discharging of the battery when the battery is in predetermined operating state;
- wherein the hermetically sealed protective housing has a receiving space for the battery housing and is part of an implantable medical device;
wherein the detector element is constructed and arranged to deflect, at least in part, in response to occurrence of said predetermined operating state of the battery, wherein the switching element is positioned so as to be activated by deflection of at least part of said detector element; and
wherein said detector element forms part of the protective housing.

Abstract
A protective device for a repeatedly rechargeable electrochemical battery (10) with a battery housing (12), the protective device having at least one switching element (86) which can be activated by a detector element (62) and which is designed or adjusted to prevent recharging and/or discharging of the battery (10) in an impermissible operating state thereof. The protective device has a hermetically sealed protective housing (54) which holds the battery housing (12). An impermissible operating state of the battery (10) causes a change in shape (deflection) to be impressed on the detector element (62). Preferably, the at least one switching element (86) is made as a make contact which electrically short circuits a recharging circuit supplied by a charging device when a predetermined expansion in the volume of the battery housing (12) and/or gas escape therefrom occurs. The protective device is part of an implantable device, such as a hearing aid.
