Abstract:
1. A charging and discharging management apparatus comprising: a charging and discharging management chip; primary battery positive and negative electrode contacts; secondary battery positive and negative electrode contacts; electronic switches connected to the primary battery positive and negative electrode contacts and the secondary battery positive and negative electrode contacts; a detecting unit configured to detect in-place states of a primary battery and a secondary battery; and an electronic switch controlling unit connected to the detecting unit and configured to control the electronic switches to be on or off according to the in-place states of the batteries, so that the charging and discharging management chip performs charging and discharging management for a battery in-place; wherein the electronic switch controlling unit comprises: a controller; a first control interface connected to the controller, and connected to the primary battery negative electrode contact and the secondary battery positive electrode contact through the electronic switches; a second control interface connected to the controller; a comparator comprising a first comparator input end connected to the secondary battery positive electrode contact, a second comparator input end configured to input a fixed voltage, and a comparator output end; an AND gate comprising a first AND gate input end connected to the comparator output end, a second AND gate input end connected to the second control interface, and an AND gate output end connected to the primary battery positive electrode contact and the secondary battery negative electrode contact through the electronic switches, wherein the controller controls the electronic switches to be on or off by using the first control interface and the second control interface to enable the charging and discharging management chip to perform charging and discharging management for a battery in-place.
