Luxembourg bus operator orders five Volvo 7900 plug-in hybrid buses; ABB fast chargers

Volvo has received an order for 5 Volvo 7900 plug-in hybrid electric buses (earlier post) from bus operator AVL (Autobus de la ville de Luxembourg). Electric bus fast chargers will be supplied by ABB. The five buses and chargers will be delivered towards the end of this year; one of the bus chargers will be placed at the central station in Luxembourg.

AVL is buying the bus system as a turn-key solution. Volvo will be responsible for vehicle servicing including battery maintenance for a fixed monthly cost.

The Volvo 7900 Electric Hybrid can be powered by electricity for up to 70% of operating time, and offers 60% lower energy consumption than a corresponding diesel bus with 75–90% lower emissions of carbon dioxide compared with a conventional Euro 6 diesel bus, depending on the fuel used.

The ABB bus chargers are easy to integrate into existing bus lines; the inverted pantograph enables the use of a low-cost and low weight interface on roof of the bus. The modular design offers charging power of 150 kW, 300 kW or 450 kW.

The chargers are based on IEC 61851-23, the international standard for fast charging of electric vehicles, ensuring the appropriate safety systems are in place, the electrical design is in accordance with regulations, and the systems architecture and working principle are supported by wider automotive community in future.
