【Abstract】 A new practical model of prediction for SOC of Primary lithium battery was proposed for addressing the deficiency of SOC prediction. The technique of lock-in amplifier was introduced for designing a device, which was used for collecting the internal resistance. A functional model was built by the relationship between SOC and internal resistance, which could predict the SOC of lithium battery. The experiment result shows that this system can predict the SOC of primary lithium battery effectively, and the result are reliable and stable.更多还原
