IMC® Electric Bus for Milan
Milan goes Electric
The transport operator ATM Milano in Milan has expanded its fleet by ordering 90 new Solaris trolleybuses equipped with the patented IMC® technology from KIEPE. The goal is to fully electrify the bus fleet using IMC® technology by 2030.
IMC® trolleybuses charge their batteries while driving with power from overhead lines and switch to battery mode in areas without overhead lines. This allows for very flexible route planning.
The electric systems of the trolleybuses are supplied exclusively by KIEPE. Each system includes power converters for the drive as well as motors, powerful 45 kWh lithium-titanate oxide traction batteries, and auxiliary systems. During bus trips, the system transfers up to 200 kW of energy from the overhead lines to the modular traction battery, giving each bus a range of up to 24 kilometers in battery mode. This eliminates the need for lengthy recharges at each end of the route. IMC buses are capable of continuous – potentially 24/7 – operation, effectively giving them an “unlimited range.”
Advantages of IMC technology
- Emission-free public transport
- Long lifespan for trolley buses
- An off-wire range up to 24 km in battery mode
- Possible 24/7 operation • Flexibility in route planning
- Charging of the traction battery during travel, requiring fewer batteries
- Optional remote diagnostics capability
- Flexibility in route planning
