Upgrade battery buses with IMC® technology
Public transit agencies operating trolley buses carry millions of passengers every day all around the world, and they have come to recognize the reliable zero emission capabilities of modern trolley bus systems. IMC® Technology has allowed these operators to expand their service networks and improve operational efficiency.
KIEPE is at the forefront when it comes to launching innovative technology used in new systems for trolley buses. One example is our In Motion Charging (IMC®) trademark. Thanks to IMC, electric buses can operate off-wire for several kilometers without the need for constant connection to overhead lines. This innovation allows operators to expand their transport networks without the need for major infrastructure investment.
KIEPE is now taking trolley buses to the next level with two additional product developments: with just two modules from the KIEPE eBus HPC platform, a standard battery-electric bus becomes an IMC® electric bus: with the KIEPE Isolating Converter (KIC) and the automatic KIEPE Smart Currentcollector (KSC).
These innovations allow OEMs to supply their eBus platforms to new markets and operators of trolley buses can benefit from the increased competition available from vehicle suppliers.
KIEPE can provide engineering support, in addition to the supply of these products.
Just two components required for the IMC® vehicle upgrade


KIEPE Isolating Converter (KIC): A galvanically isolated DC-DC converter that is designed to meet the requirements of an overhead line on the input side and can establish a safe connection between standard battery bus components and the overhead line. By using the KIC as a battery charger, an electric bus can be converted into an IMC® electric bus.
KIEPE Smart Current Collector (KSC): A current collector for trolley buses that supports semi-automatic wiring with maximum control dynamics.
Why opt for IMC??
- Reduced battery capacity is required onboard the bus.
- Optimized installation of components owing to additional space being made available due to a reduction in the need for additional batteries
- Higher passenger capacities are possible with trolley buses up to 36 meters in length.
- Fewer batteries mean less weight and reduced power consumption.
- No downtimes, 24/7 operation is possible.
- No power peaks during charging compared to depot charging in the evening.
- Longer asset life of 20 years and more.
For high passenger count, long routes and 24/7 operation, IMC® electric buses remain an excellent alternative.
