Charging and discharging control method

The invention relates to a charging and discharging control method. The method comprises the following steps: acquiring a charge-discharge state and a working voltage of a battery; acquiring an electric energy state estimated value of the battery at the current moment; determining a charging and discharging power adjustment value of the battery according to the electric energy state estimation value of the battery at the current moment; and determining and controlling the battery to charge and discharge at the target charge and discharge power according to the charge and discharge state and the working voltage of the battery, the charge and discharge power adjustment value and the voltage threshold. Therefore, the determined target charging and discharging power has a reliable data source, the control stability and reliability of the battery energy storage system can be improved, and the service life of the battery energy storage system can be prolonged. 本申请涉及一种充放电控制方法。所述方法包括获取电池的充放电状态和工作电压；获取电池当前时刻的电能状态估算值；根
