Expertise on the procurement of electric motor powered buses

One of the objectives of this result was to offer key findings on the battery propelled vehicles. Electric buses have been running in Rome since 1989, with a large fleet of 42e- buses (5 mt buses; max capacity: 27 people; equipped with pb-acid 585 Ah batteries; autonomy of 45 km) operating on three lines inside the historical centre.
The project was aimed at extending the area where e-buses are operated through the purchase of 36 middle sized buses (9mt), in order to achieve environmental benefits.
During the four years of the project, unexpectedly a big effort had to be concentrated on the procurement of these buses. 3 tenders had to be launched.

The main requirements of the tender were:
- Improvements in the performance of batteries, mainly in their energy storage capacity (for example a limit of 200Wh/kg would be very attractive), in life cycle and, overall, in price.
- Capacity: about 40 passengers;
- Range: either 180 kilometres or 12 hours continuous operation;
- Admittance for recharging during stops at the terminus.

Technical tests have been performed on some difficult paths in Rome in order to test the main performances of the vehicles: 135 km covered with one battery charge, max speed: 55km/h, 15% slope covered. ATAC has learned a lot on the main aspect of the procurement, which is the reliability of batteries.
