Optical Storage And Charging Integrated Microgrid Solution

Product introduction:

The Huijue's Optical-storage-charging application scenario is a typical application of microgrid energy storage. The core consists of three parts – photovoltaic power generation, energy storage batteries, and charging piles.

The core consists of three parts – photovoltaic power generation, energy storage batteries, and charging piles. These three parts form a microgrid, using photovoltaic power generation to store electricity in the energy storage battery. When needed, the energy storage battery supplies the electricity to the charging pile. Through the light-storage-charging system, this clean energy of solar energy is transferred to the power battery of the vehicle for the vehicle to drive. According to the demand, the integrated light-storage-charging charging station can achieve two grid connections and off-grid operating modes. When the integrated Optical-storage-charging charging station is connected to the grid, in addition to receiving energy from the photovoltaic solar panels, the energy storage battery charges when the electricity price is low and discharges when the electricity price is high, which reduces the charging cost while being able to peak shaving and valley filling, and also makes up for the disadvantage of the discontinuous solar power generation. When the power grid is powered off, the light-storage-charging system can use the off-grid operating mode to emergency charge the new energy vehicles.

Energy storage system:

The energy storage system has a battery compartment and an equipment compartment. The battery system consists of a single cell as the smallest unit to form a battery module and a battery cluster, and the battery capacity is configured according to the actual needs of the site; the equipment compartment is placed with an energy storage converter (PCS), AC distribution cabinet, DC distribution cabinet, fire protection system, and EMS & dynamic loop monitoring cabinet, etc. The energy storage system is connected to the system through the AC bus to improve energy utilization efficiency and balance the production and supply of the power system.

Charging pile:

The charging pile interacts with users through the code-scanning charging method. The charging pile system includes intelligent monitoring and intelligent measurement. The charging pile intelligent controller has the functions of measurement, control, and protection for the charging pile, such as operating status detection, fault status detection, and linked control during the charging and discharging process; the AC output is equipped with an AC smart electric energy meter for AC charging measurement, with complete communication functions, and can upload the measurement information to the charging smart controller and the network operation platform through RS-485 respectively.
