DC/DC EV Charger

Fast charging with battery storage during grid congestion

Charge electric vehicles directly from battery storage, solar panels or other DC sources without unnecessary AC/DC conversions.


A DC/DC EV charger makes it possible to charge electric vehicles directly from a battery energy storage system (BESS), solar panels or other DC sources. This enables high-power charging at locations where the available grid connection has limited capacity.

The solution is particularly valuable for businesses that want to expand their EV charging infrastructure despite grid congestion. The DC/DC connection also avoids unnecessary conversions from DC to AC and back to DC.

DC/DC EV charging as a solution to grid congestion

Many businesses try to solve this problem by installing a battery energy storage system (BESS) as a traditional support solution. However, this results in significant efficiency losses because the electricity must constantly be converted from direct current (DC) to alternating current (AC) and back again.


Meet our DC/DC EV charger. We bypass the limitations of the power grid and prevent these energy losses by connecting chargers directly to DC sources such as battery storage systems, solar panels and DC generators.

How does a DC/DC EV charger work?

A conventional DC fast charger is powered by an AC grid connection and converts alternating current into direct current for the electric vehicle’s battery. When a battery energy storage system is used as the energy source, this can result in multiple conversion stages.


A DC/DC EV charger connects directly to the DC side of the energy system. Energy from a high-voltage battery, solar panels or other DC sources can therefore be used to charge an electric vehicle directly.

Features of our DC/DC EV charger

No unnecessary conversion losses

The direct DC-to-DC connection prevents valuable energy from being lost within the battery chain.

Battery-agnostic

Works seamlessly with any type of battery or DC source, including BESS, solar panels and fuel cells.

Plug-and-play microgrid

Ready for DC microgrids without requiring additional external power supplies or components.


DC fast charging from 40 kW to 320 kW

Modular output ranging from 40 kW and 120 kW up to 320 kW, with a wide input voltage range of 250 to 950 VDC.

Intelligent controller

Full support for OCPP, Modbus and CAN, providing real-time insights into charging sessions, scheduling and load balancing.

Customisable design

A robust outdoor enclosure that can easily be customised with your company logo and corporate branding.


Benefits of DC charging from battery storage

  • Bypass grid limitations and reduce installation costs
    Instead of waiting for an expensive—or impossible—grid upgrade from the grid operator, our DC/DC platform allows you to build your own local energy ecosystem. This immediately reduces your investment and operating costs because far fewer separate components are required.
  • Greater efficiency than traditional BESS connections due to fewer conversion stages
    In traditional systems, electricity follows an inefficient route: from DC to AC and then back to DC. These conversions result in significant efficiency losses. By choosing the DC/DC platform, you eliminate these steps and achieve a system that is 10% to 20% more efficient.
  • Modular and tailored to your project
    Ysebaert nv supports you from start to finish. We can calculate and supply one, several or all the building blocks required for your installation. Already have a high-voltage DC system? No problem. Our platform can be integrated seamlessly into your existing DC infrastructure.
  • Integrate the DC charger with an EMS and load balancing
    Your energy management must operate flawlessly. Using Modbus, the system can be fully integrated with an existing on-site energy management system (EMS). Don’t have an EMS yet? We can help you select the right solution.
  • Infinitely scalable and modular
    The power grid may be constrained, but your ambitions are not. With our DC/DC platform, you can start small and scale without limits as the charging demand from your fleet or customers grows. Power is produced and supplied locally, right where it is needed.
  • Combine all your DC sources
    Combine solar panels, BESS batteries, fuel cells and DC generators in one smart, balanced solution. The platform creates a fully integrated ecosystem in which every component works together seamlessly.
