320kW High-Power DC-DC EV Charger
Dual 160kW DC-Coupled Fast Charging Station with Direct DC Input
The Ampernext 320kW DC-DC EV charger is a high-power fast charging solution designed for direct DC input environments. Delivering two independent 160kW outputs, it supports demanding rapid charging applications while enabling efficient integration into modern energy systems.
Built around a modular DC-DC power conversion platform, this charger eliminates unnecessary AC conversion stages when operating from DC sources, improving overall system efficiency and simplifying infrastructure design.
While the primary focus is high-power DC-DC charging, the system is particularly well suited for installations where EV charging operates alongside:
-
Solar PV generation
-
Battery storage
-
Microgrid environments
-
Smart energy management systems
This makes it a strong candidate for renewable-integrated EV infrastructure without requiring complex additional conversion stages.
High-Power DC-Coupled EV Charging Architecture
Unlike conventional fast chargers that rely solely on AC grid input, this system is engineered as a true DC-DC EV charger. It is capable of operating directly from:
-
Battery energy storage systems (BESS)
-
Hybrid renewable installations with solar and utility grid
-
Industrial DC distribution backbones
This architecture reduces conversion losses and enables flexible deployment in projects where EV charging is integrated with broader energy strategies.
