Safety disconnection device for automobile battery - uses circuit breakers between series battery cells released in response to abnormal retardation resulting from accident

摘要

The safety disconnection device comprises a number of mechanical contact breakers (7) allowing the series circuit provided by the individual battery cells (20 to be interrupted at a number of points in the case of an accident. The contact breakers may be released upon detection of an abnormal retardation, e.g. via a central release device (8) and are contained in a common housing in the same layout as the battery cells. The release device may be attached to a release cable (10), passed around the outside of the battery housing. USE - For preventing fire risk due to battery short-circuits in case of vehicle accident.
