Sustainable Mobility in Public Transportation

In terms of environmentally friendly transportation, trolleybuses have the advantage over buses with combustion engines. But they also have a drawback: They have to be used with an overhead line that provides a connection to the energy grid. Voltabox has developed modern auxiliary batteries for this purpose. The high-performance lithium-ion battery systems are used to bridge short to medium distances without overhead lines.

This Voltabox technology has already proven itself with several hundred battery systems in the field.

The Advantages

Zero Emissions

No more noisy and polluting diesel engines. This significantly reduces emissions and helps achieve environmental targets.


Electric buses with Voltabox battery systems drive autonomously without a direct power supply from the grid – functioning regardless of the weather and time of year thanks to integrated thermal management.

Versatile Application Possibilities

Thanks to the modular design of the high-performance batteries, Voltabox can tailor the systems precisely to customer requirements. In this way, each customer receives an individual solution that is specifically adapted to their application. Cell chemistry and design, energy content and thermal management are designed accordingly and configured for the given space and weight specifications as well as the specified system voltage levels. With Voltabox battery systems, the specifications for range and acceleration in trolleybuses and electric buses are guaranteed to be met.
