Definitions
- the present invention relates to a device for the controlled transfer of electrical devices operating according to galvanic principles from a first operating state to at least a second operating state, in which the functionality and in particular the reaction potential of the galvanic-based electrical device is reduced or completely eliminated.
- a malfunction state is to be understood as meaning states which markedly impair or render impossible any further controlled or controllable and, in particular, safe operation of the accumulator.
- Such malfunction states can be generated or triggered by a malfunction within the accumulator or by a malfunction in the environment of this accumulator.
- a malfunctioning state to be treated separately is the dangerous state which occurs due to an accident of the supplied motor vehicle or due to other, at least partially destructive, events.
- a dangerous state a controllable and safe operation of the accumulator is also no longer possible.
- a possible uncontrolled discharge of the stored energy poses a particular hazard to the occupants of the motor vehicle or other persons in the surroundings of the motor vehicle, for example for rescue personnel.
- the controlled transfer to this second operating state is desirable.
- Another known from the patent application US 2006/0019150 A1 safety device provides to provide the housing of a cell or a cell stack with predetermined breaking points, which give in at a predetermined internal pressure and regularly evolved steam offer a deduction option. Furthermore, the predetermined breaking points are designed in such a way that, when they break apart, they interrupt the electrical conduction between the identically polarized electrodes of a cell and the corresponding current conductor of the assembly.
- a disadvantage of this embodiment is that, for example, a cell stack with only one failed cell loses all of its functionality, i. the stored energy in the intact cells can no longer be used.
- lithium-ion batteries Since the safety requirements for lithium-ion batteries, especially in the automotive industry are very high and such a battery should be simultaneously economical, it would be desirable if the lithium battery or at least a number of cells contained therein in particular in hybrid, electric or stationary operation in the malfunction state and / or failure the complete reaction potential, ie the stored electrical energy or the stored potential and thus would have lost its functionality.
- the present invention is therefore an object of the invention to provide a safety device of the type mentioned above, which converts operating according to galvanic principles electrical equipment in malfunction mode of any kind and / or failure, controlled in a non-hazardous operating condition. Furthermore, a method is to be specified, which allows the detection of a malfunctioning state and ensures a controlled transfer of working according to galvanic principles electrical device.

- the active device is sufficiently thermally stable to withstand short-circuit currents flowing therethrough which are substantially in the range of one to several hundred amperes.
- the mechanical stability of the active device is designed in such a way that energy can be transmitted from the displacement device to the active device, which is sufficient to penetrate at least one component and / or cell of the electrical device operating according to galvanic principles.
