现有电池 SOC 预测方法,大都基于开路电压、开路电流等外电路或者测量电源内阻的方法,而没有考虑到电源的内在特性,尤其没有考虑电池的自恢复效应的影响,且大都采用恒压、恒流放电的工作模式,难以实现对电池 SOC 的动态预测。针对电池 SOC 预测方法的缺点,提出了一种包含有电池自恢复效应的电池 SOC 动态预测方法:提出一款包含有电池自恢复效应的动态电池模型,基于此电池模型提出了计及电池自恢复效应的动态放电模型,并论述了此放电模型与自恢复效应的关系,仿真结果表明,本预测方法具有较高的预测精度,且可实现动态预测。
現有電池 SOC 預測方法,大都基于開路電壓、開路電流等外電路或者測量電源內阻的方法,而沒有攷慮到電源的內在特性,尤其沒有攷慮電池的自恢複效應的影響,且大都採用恆壓、恆流放電的工作模式,難以實現對電池 SOC 的動態預測。針對電池 SOC 預測方法的缺點,提齣瞭一種包含有電池自恢複效應的電池 SOC 動態預測方法:提齣一款包含有電池自恢複效應的動態電池模型,基于此電池模型提齣瞭計及電池自恢複效應的動態放電模型,併論述瞭此放電模型與自恢複效應的關繫,倣真結果錶明,本預測方法具有較高的預測精度,且可實現動態預測。

Most existing battery state of charge(SOC)prediction methods are based on external circuit measurement such as open circuit voltage and open circuit current or internal resistance measurement of the power. They have not taken into account the inherent characteristics of the power supply,especially the self - recovery effect of the battery. In addition,most of these methods use constant voltage or a constant current discharge mode,which is difficult to a-chieve dynamic prediction of battery SOC. Considering these disadvantages,the paper presents a dynamic prediction method for battery SOC with self - recovery effect. The dynamic battery model including self - recovery effect is pro-posed. Based on the model,the dynamic discharge model considering self - recovery effect is proposed,and the rela-tionship between the model and the self - recovery effect is discussed. Simulation results show that the proposed pre-diction method has higher accuracy,and can achieve dynamic prediction.
