EBC-B-150S SiC

It is the first in Poland two-way charger for electric buses in energy-saving SiC technology, in the V2G (Vehicle-to-Grid) standard.

Parameters EBC-B-150S SiC

Power 150 kW

The EBC-B-150S charger is able to charge the battery of an electric bus with a capacity of 250 kWh in less than 2 hours.

Efficiency 96%

This means significantly lower costs of daily charging and using of electric buses in urban transport.

SiC technology

The use of silicon carbide technology reduces energy losses during each charging of an electric bus by an additional 2%.

V2G standard

The bidirectional flow of energy allows you to use the electric bus as a mobile energy storage unit and integrate it with the power grid.

What is V2G?


is the new standard for sustainable electricity management.

The V2G charger allows you to transfer electricity in two directions.

As a result, each electric vehicle is not only an energy consumer, but also a supplier and part of the energy ecosystem.


An electric vehicle connected to the V2G charger may constitute an additional, temporary source of power supply for the company’s own needs, e.g. in the event of a sudden failure of the power grid.


The two-way flow of energy in the charger allows you to turn electric vehicles into a system of distributed energy storage, and supply it to the power grid in crisis situations, e.g. during natural disasters, thus balancing the entire power system.


V2G is an opportunity to implement and popularise new business models. The energy stored in the battery of an electric vehicle can be sent to the grid, and sold during high tariff hours and bought when it is most profitable. Thus, we reduce the operating costs of EV fleets.


The integration of the charger with an intelligent charging module allows you to manage the process of charging and discharging the battery so that it is the most profitable for the user. At the same time, it guarantees that the electric vehicle will be ready to drive whenever it is needed.


The V2G technology popularised on the market is conducive to the development of renewable energy sources, and can help stabilise the energy system and balance energy from dispersed sources with high variability in its generation, such as wind farms or solar farms.
