使用安时积分法估算电池荷电状态(SOC)在工业上已有广泛应用，但对于风光互补发电系统来说，使用开路电压(OCV)校准安时积分法的累积误差不切实际，因为OCV法需要电池静置数小时。针对此问题，提出一种新的校准方法，该方法与OCV法类似，但校准条件只需要电池电流恒定或小范围波动维持4 min，更适用于校准风光储能系统中使用安时积分法存在的误差累积问题。使用4串6并的软包钴酸锂电池进行试验测试，在3.9、3.6、3.2 V三个不同电压平台中，所提出的策略与实际OCV误差均小于10 mV，换算成SOC均小于1%，证明了本文所提出策略的可行性。

The ampere-hour integral method in industry to estimate the state of charge (SOC) of battery. However, it is impractical to use open circuit voltage (OCV) to calibrate the cumulative error of ampere-hour integral method for wind-solar energy storage systems. Because the OCV method requires the battery to be stationary for several hours. To address this problem, a new calibration method is proposed, which is similar to the OCV method, but its calibration conditions only require the current of battery constant or maintain 4 min fluctuation in a small range, which is more suitable for calibrating the error accumulation problem in wind-solar energy storage systems using the amperehour integral method. 4S6P soft pack lithium-ion batteries is used for experimental testings in 3.9 V, 3.6 V and 3.2 V about three different voltage platforms, the proposed strategy and the actual OCV error were less than 10 mV, and the conversion to SOC is less than 1%, which prove the feasibility of the proposed strategy.
