Abstract

An electric leakage protection method based on a miniature energy storage system comprises the following steps: detecting zero line current and live wire current of a commercial power output end of the miniature energy storage system, performing subtraction on the zero line current and the live wire current, comparing a difference value with a first fusing threshold value, and controlling the miniature energy storage system to stop working if the difference value exceeds the first fusing threshold value. By adopting the method and the system, a mechanical fusing switch does not need to be additionally arranged, the size of the micro energy storage system is reduced, the current difference value is monitored, and the micro energy storage system can be rapidly controlled to stop working whenthe current is abnormal. In addition, the invention also provides an electric leakage protection system based on the miniature energy storage system.

Description

technical field [0001] The present application belongs to the technical field of safety protection of micro energy storage systems, and in particular relates to a leakage protection method and system based on micro energy storage systems with small volume and sensitive response. Background technique [0002] With the development of life, more and more users like to travel in the wild or by the sea, and need to carry energy storage devices to charge portable electronic devices during the trip. Due to the need to carry many daily necessities for outdoor travel, users have requirements for the size and weight of functional equipment. Traditional energy storage equipment is bulky, and the mechanical structure adopted for overcurrent power failure makes the response time of leakage protection lag, which is easy to damage electronic equipment. Contents of the invention [0003] The purpose of this application is to provide a small and responsive leakage protection method based ...
