The invention discloses a short-circuit protection system and method of a battery and electronic equipment, relates to the technical field of battery protection, and solves the problem that a field effect transistor is easy to damage due to short circuit. The specific scheme comprises a battery pack, a protection circuit, a first switch circuit, a current detection circuit and a control unit. The first end of the battery pack is connected with the first end of the first switching circuit. The second end of the battery pack is connected with the first end of the protection circuit. The second end of the first switching circuit is connected with the second end of the protection circuit, and the third end of the first switching circuit and the third end of the protection circuit are respectively connected with the control unit; the input end of the current detection circuit is connected with the first end of the protection circuit, and the output end of the current detection circuit is connected with the control unit; the current detection circuit is used for detecting the loop current of the short-circuit protection system of the battery; and the control unit is used for performing short-circuit protection on the first switching circuit by using the protection circuit when the loop current is determined to be greater than the reference current.
Description
technical field [0001] The present application relates to the technical field of battery protection, and in particular, to a battery short-circuit protection system, method and electronic device. Background technique [0002] With the increasing use of lithium batteries in communication base stations, data centers and other fields, the safety requirements for lithium battery management systems are also getting higher and higher. Among them, short-circuit protection plays a very important role in the reliability and stability of the entire lithium battery management system. [0003] In the prior art, the short-circuit protection of the lithium battery management system usually adopts the method of delay determination, that is, when the micro-control unit recognizes that the lithium battery management system is short-circuited, it will be judged again whether the lithium battery management system is in a short-circuit state after a certain period of time. . If it is, it is c...
