A new method of the SOC estimation using the Luenberger observer technique is presented in this paper. The simulation model of the proposed SOC estimation method is modeled in Matlab/Simulink and is generated into code automatically by Matlab/RTW. Then the code is embedded into battery management system (BMS) for SOC estimation. To investigate the feasibility and reliability of the proposed approach, the constant-current constant-voltage (CC-CV) charging test and Beijing dynamic stress test (BJDST) are performed to estimate the SOC. Results show that the proposed approach can accurately estimate the SOC within 2% error, which is adaptable for engineering application.
