Description

Product Description

The core of V2G (Vehicle to Grid) technology enables bidirectional interaction between electric vehicles (EVs) and the power grid. By leveraging EVs’ energy storage systems as a supplement to the grid and renewable energy sources, it utilizes peak-valley electricity price differences. EVs charge during low-demand periods and feed energy back to the grid during peak-demand periods, optimizing storage utilization.

The product’s power section employs advanced three-level technology in the AC/DC conversion stage for efficient bidirectional AC-DC transformation. In the DC/DC stage, high-frequency isolated bidirectional conversion (soft-switching resonant technology) ensures high efficiency and automatic energy flow reversal during charging/discharging. A dual-DSP architecture guarantees stable AC/DC and DC/DC performance. It supports module paralleling and includes CAN/RS485 communication interfaces for third-party device integration.

This power solution is widely applied in energy storage, battery formation/grading, emergency power supplies, and equipment aging tests, making it the top choice for industries requiring bidirectional energy flow.

Applications

Energy Storage (EV V2G)
With EV adoption projected to reach 80 million units by 2030, EVs can serve as flexible loads and distributed energy resources. V2G enables cost-effective charging during off-peak hours and revenue generation via peak-hour discharging. It enhances grid flexibility, reduces infrastructure investments, promotes clean energy integration, and accelerates EV industry growth while minimizing public charging footprint.

Energy Storage (Battery Repurposing)
The product offers embedded PCS solutions for flexible energy storage system design. Isolated bidirectional AC/DC converters improve safety, efficiency, and compactness. Grid-tied/off-grid hybrid units support microgrids (e.g., islands, remote villages) and mobile storage for events like G20 summits, Boao Forums, or exams.

Battery Formation & Grading
High-frequency isolation replaces bulky line-frequency transformers, boosting efficiency, cutting costs, and reducing footprint. Battery packs connect directly to modules, streamlining systems 

DC Power Aging
Integrating V2G modules during DC power aging recycles at least 95% of energy back to the grid, slashing electricity costs and production expenses.
