In Nice, France, it has been operating for trams for 16 months: Alstom's SRS ground-based recharging system. Alstom has now presented a version for e-buses in Malaga, Spain. Ground-based recharging of batteries can replace charging via a pantograph. For the time being, it is a prototype that Alstom has built in Malaga as part of the 'Paloma' project (Prototype for Alternative Operation of Mobility Assets).

The e-bus drives to the bus stop and makes contact with the SRS charging system via its 'SRS control unit'. The tolerance that the driver has to place the bus above the plates is seventy centimeters in the longitudinal direction and 25 centimeters sideways. It takes about one second for the vehicle and SRS loader to contact each other. The communication between the vehicle and the SRS system ensures rapid charging of the batteries, four to five minutes for a full charge. SRS is in principle suitable for every electric bus and battery technology.

The first SRS bus stop was built in Malaga in front of Malaga's Industrial Engineering school as part of bus line 1. The public transport company EMT in Malaga runs this line with a Linkker 12m electric bus, among others and is charged with the 200 kW at this stop. The Paloma project in Malaga has been co-funded by the European Regional Development Fund (ERDF) and CDTI. In this project Alstom works together with Mansel & Endesa, the city of Malaga, EMT Malaga and Malaga University. Alstom supplied the SRS charging system and the electric bus, Endesa the connection to the electricity grid and Mansel was responsible for the construction. For Eric Marie, Vice President Systems & Infrastructure at Alstom, the company sees a role for the SRS system as a charging solution for the future - within ten years! - for huge fleets of electric buses in 'all over Europe' cities.
