Design of Online Joint Monitoring of SOC and SOP for Lithium Battery in Electric Vehicles
Considering that the state of charge(SOC)and the peak power(SOP)are important parameters affect-ing the lithium battery power source of electric vehicles,an online joint monitoring device of SOC and SOP for lithi-um battery has been designed.The system uses the STC12C5A60S2 microcontroller as the main controller,and the voltage and current acquisition module completes the acquisition of the working status information of the electric ve-hicle battery.Through the analysis and processing by the main controller,the online estimation of SOC and peak power SOP is completed.By designing and applying Bluetooth technology,OLED display module,and mobile App module,the portable online joint monitoring function of battery SOC and SOP is ultimately realized.The results show that the system operates stably and the estimation is accurate,providing market reference for the application and promotion of lithium batteries in electric vehicles.
