摘　　要：针对在一次性锂电池电量预测方面所存在的不足,提出一种新型实用的一次锂电池SOC预测方案。该系统采用锁相放大技术设计一款交流内阻测量装置,采集锂电池交流内阻,根据交流内阻与SOC变化关系构建函数模型,并以该模型实现一次锂电池SOC预测。实验结果证明,该系统可有效用于一次性锂电池的电量预测,且测试结果较为可靠。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.
