Considering the online measurement accuracy of the traditional lead-acid battery SOC(state of charge)prediction methods is not high,the forecasting method based on electrochemical theorem is proposed.Firstly,the method discharges the battery,and the concentration of sulfuric acid is obtained by using the relationship between discharge current ,voltage and sulfuric acid.Then,the electrolyte density is gained according to the relationship between the concentration of sulfuric acid and electrolyte density.And finally get the SOC using the corresponding relation pf electrolyte density and SOC.The experiment results prove that the method has the advantages of convenient operation, high accuracy of real-time monitoring.
