Prefabricated PV-Storage-DC Flexible Super Charging Station
The Prefabricated PV-Storage-DC Flexible Super Charging Station system is a rapid deployment charging solution composed of a photovoltaic power generation system, energy storage system, charger (pile) equipment, and a DC system. Against the backdrop of a surge in new energy vehicle ownership, the prefabricated structure facilitates accelerated deployment across multiple scenarios, meets the destination charging needs of new energy vehicles, and achieves green construction requirements for land saving, energy saving, material saving, water saving, and environmental protection.
The Prefabricated PV-Storage-DC Flexible Super Charging Station system belongs to the category: Key Energy-saving Technology/Equipment (Product). Suitable for various urban environments, it solves the problems of low efficiency and long construction cycles of traditional charging stations.
Technical Principle
The system access method allows the host unit to be placed as close as possible to the charging piles. The energy of one DC charging host can be optimally dispatched to each charging pile, minimizing DC power consumption and maximizing the output current of the charger.
Scope of Application
Suitable for rocky hard ground, cement hard ground (asphalt hard ground), medium-hard soil, and medium-soft soil ground. Can be rapidly deployed in urban commercial centers, government office buildings, residential areas, etc.
System Advantages
Modular design, prefabricated structure, rapid deployment, short construction period (approx. 5 days).
Reduces on-site construction, lowers noise, prevents dust, reduces environmental pollution, clean transportation.
Saves resources such as water, electricity, and materials, adhering to sustainable development principles.
The prefabricated PV-Storage-Charging-DC-Flexible system consists of photovoltaic power generation, energy storage system, and charger (pile) equipment, connected via a "T" junction to the DC busbar as the confluence system.
Core Components
Solar PV Carport: Length 7500mm, installed with solar PV panels.
Charging Piles: Configured with two types: one pile with two guns (0~40kW) and one pile with one gun (0~40kW).
Energy Storage System: Uses lithium-ion batteries to store excess solar energy or off-peak grid electricity.
Construction Process
R&D and Design Phase: Select design plan based on the project location, configure Hailiang V2.0 solution.
Production, Assembly, and Debugging Phase: Complete production, assembly, and inspection of the charging station system in the factory.
On-site Installation and Configuration Phase: Level and prepare the site, complete power point and grounding grid setup, deploy the prefabricated system.

Basic composition of the prefabricated PV-Storage-Charging system: Charger (pile) and power stack, prefabricated substation, system energy storage, system photovoltaics, charging pile foundation base, etc.
System Process
Charging station construction is first produced and fully configured in the factory according to typical plans.
On-site construction workload is minimal, mainly involving site leveling and reinforcement work.
Overall on-site work content is completed within approximately 3~5 days.
Technology Comparison
Conventional Charging Station: Long construction period (at least 30 days), construction occupies 2/3 of the time, significant impact on the surrounding environment.
Prefabricated Charging Station: Short construction period (approx. 5 days), factory prefabrication, rapid on-site installation, minimal environmental impact.
