This 20kW wide-range constant-power EV charger module is built for the next generation of DC fast charging stations. It serves as the core power unit for high-performance, high-availability charging systems. With advanced power-electronics control and a fully modular design, it delivers strong power density, high conversion efficiency, and excellent voltage adaptability. It also stands up well to heat, cold, vibrations, and the harsh conditions found in real charging environments.
The module supports an ultra-wide DC output range—typically 200 to 1000V—and maintains a steady 20kW across the full voltage window. This gives it broad compatibility. It works smoothly with today’s mainstream EVs and is ready for future high-voltage platforms, including 800V architecture vehicles. Peak conversion efficiency above 95% helps cut operating costs, reduce heat load, and extend the lifespan of the entire charging system.

An EV charger module is the heart of any DC fast charging system. It’s the unit that quietly does the heavy lifting — turning AC power into the stable, high-quality DC energy that modern electric vehicles rely on. Whether the module is installed in a public charging station, a fleet depot, or a commercial energy hub, its job is simple: deliver clean, steady power, charge after charge, in all kinds of conditions.
Unlike complete chargers that you see in parking lots, the module works behind the scenes. It provides the raw power output that determines how fast and how safely an EV can charge. A high-efficiency module keeps energy loss low, reduces heat, and helps operators cut long-term costs. With wide voltage adaptability and constant-power output, it supports today’s mainstream EVs and the next generation of high-voltage platforms without needing hardware changes.
For charging manufacturers and system integrators, the EV charger module is where reliability starts. It’s compact, responsive, and built for continuous operation. It offers precise control, smooth communication, and a full suite of safety protections. And because it’s modular, it scales effortlessly — one unit, or dozens working together, depending on the size of the site.
It may not be visible to drivers, but it’s the backbone of fast charging everywhere. A dependable module keeps stations running, vehicles moving, and charging networks ready for the road ahead.
