V2G (Vehicle to Grid) —
enables bidirectional interaction between electric vehicles and the power grid,
using EV energy storage as a supplement to the grid and renewables.
Charge during off-peak hours and discharge during peak hours to leverage
price differences.
V2L (Vehicle to Load) —
turns an EV with a bidirectional charger into a mobile power station,
supplying 220V or 380V AC loads — a large-scale portable power bank.
The AC/DC stage uses 3-level technology for bidirectional
AC/DC conversion. The DC/DC stage employs high-frequency isolated
bidirectional conversion with soft-switching resonant technology
for high efficiency and automatic charge/discharge switching.
Dual-DSP design ensures stable bidirectional performance.
Supports parallel operation, CAN and
RS485 communication for easy integration with third-party
equipment.
⚙️ Product Advantages
Safer & More Reliable
Full high-frequency isolation ensures battery-to-grid/load safety. DSP+CPLD digital control with multi-level overvoltage, overcurrent, overtemperature protection. Dual-DSP for stable performance. Reliable parallel operation — up to 12 modules.
High Efficiency
Eliminates line-frequency transformers. High-frequency isolation achieves >95% efficiency. AC/DC 3‑level technology up to 98%. DC/DC soft‑switching resonant technology up to 98%.
Smarter & More Friendly
Supports grid‑tied (V2G) and off‑grid (V2L) modes. Covers passenger vehicle battery voltages (100V–1000Vdc). Wide grid voltage range and 50/60Hz auto‑adaptation.
Lower Cost
High‑frequency isolation removes the need for a line‑frequency transformer. One circuit handles both charging and inverting — integrated design reduces system cost.
Flexible Configuration
19‑inch rack mount, compact structure. Hot‑swappable design for flexible system configuration. Ideal for system integrators building energy storage, battery formation, or DC aging systems.
