摘要:
在大量先验数据的基础上，根据电池管理系统的采样数据，结合安时积分法和开路电压法，对电池SOC进行估算，同时考虑温度及单体电池的不一致性对电池性能的影响，根据不同温度与电池SOC之间的修正数据关系对上述算法进行高低端修正，实验结果表明此方法能够降低安时积分法估计电池SOC的累积误差，准确估算电池SOC，且具有较强的实用性和可靠性。
Abstract:
On the basis of a large number of prior data, the battery SOC was estimated according to the sampling data of the battery management system, with the combination of the ampere-hour integral method and the open-circuit voltage method. Meanwhile, considering the effects of temperature and difference of single batteries on the performance of the battery, a high-and-low-end correction of the above algorithm was based on the correction data relationship between different temperatures and battery SOC. Experimental results show that the method could reduce the cumulative error of ampere-hour integral method in estimating the battery SOC, so it can accurately estimate the SOC of the battery. In addition, this method has strong applicability and reliability.
