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."
Your Advantages
The transit agency ATM Milano has expanded its fleet with an order for 90 new Solaris trolley buses, equipped with KIEPE’s patented IMC® technology.
IMC® e-buses recharge their batteries during travel using electricity from overhead lines and switch to battery mode in areas without overhead lines. This enables highly flexible route planning.
ATM‘s goal is to fully electrify its bus fleet by 2030 using IMC® technology.
The electric systems are exclusively supplied by KIEPE. Each system includes traction inverters motors, high-performance 45- kWh lithium-titanate-oxide traction batteries, the KIEPE current collector and auxiliary power systems. During operation, the system charges the batteries with a power of up to 200 kW from overhead lines to the modular traction battery, allowing an off-wire range of up to 24 kilometres in battery mode. This eliminates the need for lengthy charging stops at the terminus. IMC® e-buses are capable of continuous – potentially 24/7 – operation, effectively achieving „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
