Embodiment
The utility model discloses a kind of battery protection system.Battery protection system comprises spaced first electrode and the second electrode; be provided with between described first electrode and described second electrode and can vary with temperature and produce the connector of deformation, described connector can make conducting or disconnection between described first electrode and described second electrode when producing deformation.
Because battery protection system of the present utility model arranges connector between spaced electrode; this connector varies with temperature and can make conducting or disconnection between electrode when producing deformation; thus can prevent battery from causing the phenomenon burst to occur because charging overheated; and system itself can not be damaged; therefore the utility model structure is simple, easy to use safe and can reuse, and useful life is longer.
Below in conjunction with accompanying drawing and preferred embodiment, the utility model is described in further detail.
The battery protection system of present embodiment comprises spaced first electrode 10 and the second electrode 20; be provided with between described first electrode 10 and described second electrode 20 and can vary with temperature and produce the connector 30 of deformation, described connector 30 can make conducting or disconnection between described first electrode 10 and described second electrode 20 when producing deformation.
First electrode 10 and described second electrode 20 are also coated with metal glazing 50; Metal glazing 50 is provided with protruding stud at the first electrode 10 and described second electrode 20 correspondence position.Described metal glazing 50 is coated with metal cover plate 60.Described metal cover plate 60 is coated with insulation board 70.Described metal cover plate 60 and insulation board 70 are provided with at the stud correspondence position of metal glazing 50 and dodge hole.Described battery protection system also comprises two copper billets, 80, two copper billets 80 and is provided with through hole 81, and described through hole 81 one end is fixed on described stud.
