IMC®-Upgrade for E-Buses

In Motion Charging: IMC®-Upgrade for E-Buses

The demands on public transportation are increasing: more flexibility, lower emissions, and reduced costs. KIEPE's patented In Motion Charging (IMC®) technology efficiently meets these requirements. As a pioneer in e-mobility products for trolleybuses, KIEPE offers a modular solution that allows existing electric buses to be converted into trolleybuses.

What is an In Motion Charging bus?

An IMC® e-bus travels on sections with overhead lines and automatically charges its battery while doing so. This allows it to continue operating purely electrically on other segments, without overhead lines and without a charging pause at the depot.

This saves costs, increases range, and reduces downtime. Additionally, IMC® e-buses can overcome steeper inclines compared to battery-electric buses or trams.

This technology merges two systems into an economical solution: trolleybus technology and battery-electric bus technology.

KIEPE Smart Current Collector (KSC)

The semi-automatic KIEPE Smart Current Collector is compactly designed, creating space for traction batteries on the vehicle roof. It is easy to integrate and offers reliable pole control: In the event of a derailment, it automatically lowers the pantographs—for increased safety and operational continuity.

KIEPE Isolating Converter (KIC)

The KIEPE Isolating Converter (KIC) is a galvanically isolated DC/DC converter that charges the battery via the overhead line while driving. The double isolation ensures reliable protection for both the vehicle and the battery. The KIC is compact, versatile, and ideal for converting a bus into an In Motion Charging (IMC®) vehicle.

How does In Motion Charging technology work for trolleybuses?

Frequently Asked Questions about In Motion Charging (IMC®) for e-buses (FAQ)

While driving under overhead lines, the battery automatically recharges. Outside the overhead lines, the bus continues to operate purely on battery power without separate charging processes or downtime at the depot.

What are the advantages of IMC trolleybuses in public transportation?

They require smaller batteries, making them lighter, more energy-efficient, and providing more passenger space. Additionally, they can operate continuously ideal for long routes and high-capacity demands.

Are trolleybuses being replaced by battery-electric buses?

No - In Motion Charging buses combine the best of both worlds: overhead line infrastructure and flexible battery usage. They remain particularly economical and reliable for cities with existing overhead wiring.

How does an In Motion Charging bus differ from a conventional e-bus?

A conventional battery-electric bus is primarily charged at the depot or bus yard. In contrast, the IMC® bus charges while driving saving charging time, energy, and reducing the strain on the power grid.

Is the IMC® upgrade also possible for existing vehicles?

Yes. The IMC® system is modular and ideally suited for integration into existing vehicle concepts. Battery-electric buses can be efficiently converted into IMC® vehicles.

How complex is the retrofit with KIEPE components?

The effort is minimal, as essentially only two main components are integrated: the KIEPE Smart Current Collector and the KIEPE Isolating Converter. KIEPE provides technical support for integration and commissioning.
