Great changes have also occurred in the power supply system, which changed from the original bulky other materials to the lithium-ion battery power supply.Lithium ion battery has the advantages of small size, light weight, low pollution and high efficiency. It has strict demand on charging and discharging control system, so it has a good performance of charge and discharge balance system is very important. This design is based on STC12C5A60S2 as the control core, PI algorithm is adopted to control the charging process in the current dynamic balance, the system consists of a display circuit, a protection circuit, a voltage sampling circuit. To achieve the basic functions of lithium ion charge and discharge control, puts forward the design idea and system structure. The system has good reliability, strong practicability, charging and discharging d...
