摘　　要：蓄电池能量管理技术是提高蓄电池使用寿命的有效手段,对于蓄电池的SOC保护逐渐成为研究热点。基于蓄电池的SOC管理和寿命管理,提出了一种关于蓄电池的SOC改进策略,并通过仿真来验证蓄电池的SOC改进是否有效。仿真结果表明,改进后的SOC电量趋于平缓下降,对蓄电池起到了保护的作用,直流母线电压也趋于稳定,对系统的功率波动有较强抑制效果,为蓄电池SOC的深入研发与应用提供了有效参考。Battery energy management technology is an effective means to improve the service life of battery,and the SOC protection of battery has gradually become a research hotspot.Based on battery SOC management and life management,a strategy for battery SOC improvement is proposed,and the SOC improvement of battery is verified by simulation.The simulation results show that the improved SOC power level tends to decrease gradually and protects the battery,and the DC bus voltage is also tends to be stable,and has a strong suppression effect on the power fluctuation of the system.It provides an effective reference for the in-depth development and application of battery SOC.
