调节电池SOC的方法和使用该方法的电池管理系统
摘要：
本发明公开一种电池的充电状态(SOC)补偿方法以及使用该SOC补偿方法的电池管理系统。用电池的充电/放电电流计算SOC和作为OCV表中的值的SOC电压，计算基电压，通过使用SOC电压与基电压之差来测量SOC的误差，并在多个有效范围中确定误差范围。随后，通过使用根据误差所处的范围而设置的补偿SOC来对SOC进行补偿，从而测量出更准确的电池SOC。
摘要（英）：

A state of charge (SOC) compensation method of a battery and a battery management system using the same. A charge/discharge current of the battery is used for calculating the SOC and an SOC voltage that is a value in an OCV table, a rheobasic voltage is calculated, an error in the SOC is measured by using a difference between the SOC voltage and the rheobasic voltage, and a range of the error is determined among multiple effective ranges. Subsequently, the SOC is compensated by using a compensation SOC set in correspondence with a range in which the error is included to thereby measure a more accurate SOC of the battery.
