One platform –
many (charging) applications
Today’s charging infrastructure must be flexible: different vehicle classes, changing grid connections, increasing power requirements, and new use cases such as bidirectional energy management. KNESTEL offers a modular DC converter platform that can be scaled, integrated, and configured for specific projects.

Our advantages
HIGH POWER: Insulated 250 kW ITS & IHTS modules – scalable up to several MW
The 250 kW modules form the basis for high-performance charging infrastructure. Parallel operation allows configurations of several MW, making the modules ideal for depot charging, fast charging hubs, and heavy-duty applications.
Details:
- 250 kW is one module
- Modules can be connected in parallel = up to several MW
- Scalable and expandable in the field (depending on the project)
URBAN/MID POWER: 50–100 kW for city, fleet, and grid limits
Compact power classes are crucial for locations with limited grid connection or for plannable fleet charging windows. The 50–100 kW modules enable economical charging points in urban areas – based on the same platform architecture.
Examples of use:
- City charging points and neighborhood solutions
- Corporate and municipal fleets
- Locations with limited connection capacity
OPTIONAL: Galvanic isolation for safe system separation
Depending on the system design and requirements, the platform can be designed with galvanic isolation. This supports safety concepts, standard-compliant system separation, and reliable operation in demanding environments.
Details:
- galvanic isolation depending on project requirements
- suitable for demanding infrastructure environments
- Integration into existing security concepts
BIDIRECTIONAL: Actively control energy flows
The platform is bidirectional and thus supports applications in which energy not only flows into the vehicle, but also back out again, e.g., for peak load reduction or for future energy management concepts (project-specific).
