Abstract

A battery cell is disclosed. The present invention teaches a battery cell comprising a first switching member switchable between a first position and a second position, wherein, in the first position of the first switching member, the first electrode of the battery pack ( 14) is connected to the first terminal (14A) of the battery unit (10). In the second position of the first switching member (18), the first electrode (14) is separated from the first terminal (14A). The battery unit (10) may further include a control unit (20) in order to control switching of the first switching member (18). Optionally, there may be a second switching member (22) which, once the first terminal (14A) is separated from the first electrode (14) in response to a critical state of the battery cell (10), the second switching member (22) A bypass is provided between the second electrode (16) and the first terminal (14A).

Description

technical field [0001] The present application relates to battery cells and methods of operating battery cells. Background technique [0002] Battery cells and especially rechargeable battery cells are not only reliable sources of energy in mobile and / or portable devices such as cars, vehicles, mobile telecommunication devices and mobile computers. In recent years, lithium-ion-based batteries, in particular rechargeable lithium-ion batteries or accumulators, for example, have been known in the art. [0003] Some of the known batteries are sensitive to environmental conditions, charging and / or discharging (ie charging protocol). If such cells are not handled in accordance with the prescribed protocols for charging and / or discharging, these batteries may cause fire, generate considerable quantities of potentially toxic gases, and may cause Explosion and / or rupture of the case of one or more known batteries. [0004] Further with some of the known batteries, problems may ari...
