Overview
The Ampernext 240kW is a high-power DC-DC fast charging module engineered for system integrators building mobile EV charging stations. It converts external DC energy into regulated DC fast charging for electric vehicles and is intended for use in battery-powered, fuel-cell-powered, or hybrid mobile charging platforms.
This unit can be coupled to any external DC supply from batteries, fuel cells, hybrid systems, or other DC energy sources. It provides the core charging capability for deployable and off-grid EV charging systems, enabling builders to create professional mobile charging infrastructure with infrastructure-grade performance.
Who This Product Is For
The 240kW DC-DC charger is ideal for companies and integrators who are:
Designing vehicle-mounted mobile EV charging stations
Building battery-buffered fast charging systems
Developing fuel-cell-powered charging platforms
Integrating hybrid DC energy and charging solutions
Deploying temporary or off-grid mobile charging infrastructure
Supporting fleets or emergency charging operations
This module is intended for engineering teams, system integrators, energy solution providers, and charging-as-a-service operators who need a reliable, high-power charging block for mobile deployments.
Changing the Paradigm of Mobile EV Charging
Traditional EV charging relies on fixed, grid-connected stations — slow to deploy, limited in location, and dependent on infrastructure upgrades. The Ampernext 240kW DC-DC charger enables a new approach: modular, deployable, and energy-independent mobile charging systems.
Builders and integrators can:
Integrate the charger into vehicle-mounted or transportable platforms
Combine it with batteries, fuel cells, hybrid DC systems, or microgrids
Deploy off-grid, high-power mobile charging anywhere without fixed infrastructure
Scale temporary or event-based charging networks quickly
Create on-demand charging solutions for fleets, remote areas, or emergency services
This module shifts the focus from static infrastructure to flexible, energy-independent, deployable mobile EV charging systems, enabling a new class of charging-as-a-service and mobile infrastructure solutions.
