The invention discloses an electric vehicle group charging control method, device and equipment and a medium, and the method comprises the steps: determining a charging load base line according to the historical charging record of an uncontrolled electric vehicle group, obtaining the charging capacity margin of a controlled electric vehicle group according to a resident total load curve and the capacity of a transformer in a transformer area, and determining the chargeable probability; when it is detected that any to-be-charged vehicle is connected to the charging pile, the charging duration is determined according to the target charging electric quantity of the vehicle and the rated power of the charging pile, and the charging starting time period is determined according to the vehicle arrival time and the vehicle departure time; according to the chargeable probability, the charging starting probability of the to-be-charged vehicle in the charging starting time period is determined, a charging starting time sequence is obtained through a receiving rejection sampling method, and charging starting time is extracted from the charging starting time sequence; and generating a control instruction according to the charging starting time, the charging pile rated power and the charging duration, and sending the control instruction to the charging pile. According to the invention, a plug-and-play electric vehicle group charging strategy can be generated under the condition of abnormal communication.

    本发明公开一种电动汽车群充电控制方法、装置、设备及介质,方法包括:根据不受控电动汽车群的历史充电记录确定充电负荷基线,并根据居民总负荷曲线和台区变压器容量,获得受控电动汽车群的充电容量裕度并确定可充电概率;当检测到任意待充电车辆接入充电桩时,根据其目标充电电量和充电桩额定功率,确定充电时长,并根据车辆到达时间和车辆离开时间确定开始充电时段;根据可充电概率,确定待充电车辆在开始充电时段内的开始充电概率,并利用接收拒绝采样方法获取开始充电时间序列,在其中抽取开始充电时间;根据开始充电时间、充电桩额定功率和充电时长生成控制指令并发送至充电桩。本发明能在通信异常情况下生成即插即用的电动汽车群充电策略。
