Publication number: 20210376631Abstract: A battery detection system includes a battery assembly and an electronic device. The battery assembly includes a first connector and a detection module connected to the first connector. The electronic device includes a second connector and a control module connected to the second connector. When the first connector is connected to the second connector, the detection module is configured to output first identification information to the electronic device through the first connector. When the second connector receives the first identification information, the control module confirms that the battery assembly is in a connected state. After the first connector is disconnected from the second connector, the detection module generates and outputs second identification information. When information received by the second connector changes from the first identification information to the second identification information, the control module confirms that the battery assembly is disconnected.Type: ApplicationFiled: June 21, 2021Publication date: December 2, 2021Inventors: Hong XIE, Guanghui Chen, Xuefeng Liu
