Design of SOC Estimation System for Lithium Battery of Electric Vehicle
In order to achieve the accurate estimation of electric vehicle power lithium battery SOC,this paper designs the SOC estimation system of electric lithium battery,which mainly includes the hardware design and pro-gram design of voltage module,current module,temperature module and CAN communication module.The system is tested by using the actual lithium iron phosphate battery.The results show that the acquisition effect of voltage,current and temperature is good,and the measurement error of data is less than 2%,which verifies the practicabili-ty and effectiveness of the proposed SOC estimation system.
