Energy efficiency data judgment method, medium and system for energy storage charging and discharging of equipment

The invention discloses a method, a medium and a system for judging energy efficiency data of energy storage, charging and discharging of equipment. The method comprises the following steps: acquiring monitoring data of an equipment load from a real-time database of a production system; performing variance analysis on the monitoring data to obtain operation data of the equipment load in a certain time period, and screening out high-power operation data from the operation data; the charging and discharging time of the energy storage equipment is judged by combining the electricity peak valley and the time point set obtained through variance analysis; and the judgment process is cycled periodically, and the judgment basis and the charging and discharging time are updated in real time. The charging and discharging time of the energy storage unit in the load equipment is set in advance, and electricity waste caused by electricity utilization in peak electricity utilization time is reduced; the above variance anal
