Alstom develops gound-based charging for electric buses


Alstom shows a ground-based recharging system for electric buses, further development of its SRS system for trams. The prototype now presented in the Spanish city of Málaga is equipped with a 200 kW charger that charges a twelve-metre electric bus from Linkker.

Alstom is running the system in Malaga on bus line 1 of the local public transport company EMT Málaga. The premiere of the system is part of the EU-funded pilot project PALOMA (Prototype for Alternative Operation of Mobility Assets) led by Alstom and involving the energy utility Endesa, the electrification company Mansel, the city of Málaga, the transport company EMT Málaga and the University of Málaga.

SRS for e-buses is based on Alstom’s SRS static recharge technology for trams, a proven solution already in operation in Nice, France. Alstom says its catenary-free solutions have been sold to 12 cities around the globe and have seen more than 40 million kilometres of tram operation.

In the case of the now shown SRS for e-buses, it offers the charging of on-board equipment automatically, in “top-up” mode in a few minutes on a bus line, or within the depots, when off duty. As a ground-based solution, it eliminates the need for overhead infrastructure in cities, preserving the aesthetics of the urban landscape. In depots, SRS avoids the infrastructure costs associated with overhead charging systems and maximises ease of maintenance, with onboard access compatible with existing pits within workshops. SRS is scalable, interoperable and non-proprietary, meaning it can be used for fleets of various bus types, regardless of manufacturer or changes in battery technology.
