In places with large load fluctuations, the electric energy storage and conversion system is required to discharge during peak loads and charge during low-valley loads to effectively realize peak-shaving and valley-filling, improve grid quality, alleviate grid congestion, and reduce losses; charging process: AC-transformer – filter – rectifier inverter – filter – battery; discharge process: battery – rectifier inverter – filter – transformer – alternating current.

 Application Scenario

 Energy storage system, intelligent micro

grid system, new energy charging or

battery replacement equipment, battery

testing equipment, etc.
