14 electric dual-mode buses from Vossloh Kiepe are now in operation in Sardinia – four of them charge with In Motion Charging (IMC) and opportunity charging

The public transport company Consorzio Trasporti e Mobilità (CTM) in Cagliari has realised a 4.5 km long line extension of its electric bus system along the coast without overhead wires. Vossloh Kiepe and Van Hool delivered 14 electric dual-mode buses. Four of them have been equipped with the powerful lithium-titanate-oxide (LTO) batteries. These batteries are charged when the buses are driving under the overhead wires (In Motion Charging - IMC). In addition, the recharging is possible thru opportunity charging by a charging station at the final terminal.

The IMC battery bus is 12 metre long and can transport 85 passengers plus the driver. Thanks to the usable energy of the LTO batteries of more than 18.5 kWh and a peak power of 120 kW the buses can also accelerate powerfully in the sections without overhead wires. Therefore, the wireless line extension forth and back of altogether a length of 9 kilometres, they can easily be operated. 

The opportunity charging at the final terminal during the driver’s break prolongs the life time of the batteries because they are discharged to a lesser degree. The IMC current collector poles are used for the opportunity charging as they can automatically dock into the funnels of the charging station. Moreover, the buses have been equipped with AC charging plugs so that they can be charged in the depot when they are serviced. Generally, the batteries are charged during the journeys under the overhead wire so that the electric buses return to the depot with fully charged batteries in the evening.

This kind of line extension is a novelty and has been realised within the scope of the European research project ZeEUS (Zero Emission Urban Bus System) coordinated by the UITP (International Association of Public Transport).

The CTM has documented this trend-setting wireless operation in an impressive video, which can be found on YouTube under https://youtu.be/s25vgJKoXxY.
