The power grid charges the energy storage battery during the electricity price valley period, and the energy storage battery charges the vehicle during the electricity price peak period, reducing the charging cost

The power grid, energy storage battery, electric vehicle and new energy access four parts of electric energy are completely isolated from each other, safe and reliable

Internal high-voltage DC bus connection, DCDC conversion between photovoltaic, energy storage, and charging, unified control by EMS, 1~2% higher conversion efficiency than AC bus connection
