Abstract
A power disconnection apparatus includes a soft-shell Li ion battery and a power disconnection device. The soft-shell Li ion battery includes anode pin and a cathode pin and a soft shell enclosing the soft-shell Li ion battery. The power disconnection device includes a panel attaching to the surface of the shell of the soft-shell Li ion battery and a separation unit arranged at topside of the panel and corresponding to one of the anode pin and the cathode pin. The shell has expansion when the soft-shell Li ion battery is over-charged and the panel is move away from the soft-shell Li ion battery. Therefore, the separation unit disconnects power to the anode pin or the cathode pin.
Claims3
A power disconnection apparatus for an over-charged soft-shell Li ion battery, comprising:
- a soft-shell Li ion battery comprising an anode pin and a cathode pin, and a soft shell enclosing the soft-shell Li ion battery;
- and
- a power disconnection device comprising a panel attaching a surface of the soft shell and a separation unit connected to the panel and corresponding to one of the anode pin and the cathode pin;
- wherein the soft shell is expanded when the soft-shell Li ion battery is over-charged and the panel is moved away from the soft-shell Li ion battery, whereby the separation unit disconnects power supplied to one of the anode pin and the cathode pin,
- wherein the anode pin comprises an anode leg and an anode flange connected to one end of the anode leg, and
- wherein the anode flange of the anode pin comprises a through hole, the panel comprises an aperture thereon and the separation unit is of plate shape with openings at both ends thereof, the anode flange and the panel and the separation unit are combined by using a rivet passing through the through hole, the aperture and the openings.
