Application Areas

Energy Storage (Electric Vehicle Energy Storage V2G)

With the increasing number of electric vehicles, it is projected that there will be 80 million electric vehicles by 2030. Massive electric vehicles can serve as both flexible loads on the user side and distributed power sources, helping to regulate grid load, shave peaks and fill valleys, absorb renewable energy, and provide auxiliary services such as frequency regulation and backup for the grid, reducing distribution network investment.

This electric vehicle energy storage V2G, or bidirectional DC charging pile, can both charge and discharge with a maximum power of 250kW, covering the power demands of most current DC charging piles. It enables bidirectional energy flow between electric vehicles and the grid, allowing electric vehicles to charge with cheap or off-peak electricity and discharge during peak hours, enabling vehicle owners to earn electricity price differentials. It enhances load flexibility, reduces distribution network investment, absorbs clean energy, boosts the development of the electric vehicle industry, and reduces the land footprint of public charging facilities.

Energy Storage (Grid-Connected/Off-Grid Type)

This product is suitable for small and medium-sized industrial and commercial energy storage, such as peak shaving and valley filling, with configurations like 30kW/60kWh or 50/60kW 100kWh. Paired with STS, it can build small and medium-sized microgrids, providing power to loads during grid outages.

DC Power Supply Aging

DC power supplies, such as charging pile modules, power operation power supplies, and communication power supplies, generate significant power loss when loaded with resistive or electronic loads during production aging. If these DC power supplies are connected to V2G modules during the aging process, electricity can be fed back to the grid, saving at least 95% of electricity, reducing the owner’s electricity costs, and lowering production costs.
