Abstract
A safety circuit includes a thermal fuse electrically connected in a main current path so that an electric current flowing in the main current path flows, through the thermal fuse; a switching element electrically connected to the thermal fuse to cause the thermal fuse to open and interrupt the electric current flowing in the main current path when the switching element is turned on; a microcontroller electrically connected to the switching element and the main current path to turn on the switching element when an overcurrent flows in the main current path; and a noise removing unit electrically connecting the microcontroller to the switching element.
Claims20
A safety circuit comprising:
- a fuse electrically connected in a main current path so that an electric current flowing in the main current path flows through the fuse;
- a switching element electrically connected to the fuse to cause the fuse to open and interrupt the electric current flowing in the main current path when the switching element is turned on;
- a controller electrically connected to the switching element and the main current path to turn on the switching element when an overcurrent flows in the main current path;
- and
- a noise removing unit electrically connecting the controller to the switching element.
A battery pack comprising:
- a battery electrically connected to a main current path;
- a fuse electrically connected in the main current path so that an electric current flowing in the main current path flows through the fuse;
- a switching element electrically connected to the fuse to cause the fuse to open and interrupt the electric current flowing in the main current path when the switching element is turned on;
- a controller electrically connected to the switching element to turn on the switching element;
- and
- a noise removing unit electrically connecting the controller to the switching element.
