IRJ at UITP 2015, Milan: A new catenary-free ground-based static charging system for LRVs and electric buses is one of the highlight exhibits for Alstom at the UITP 2015 World Congress and Exhibition being held this week in Milan.
Unlike Alstom's existing APS ground power supply system, which supplies power to the vehicle continuously while in operation, SRS charges banks of onboard supercapacitors or batteries during station stops. The system is capable of delivering 1.1MW of power, or 1500 amps at 750V dc in a 20-second charging cycle, well within typical station dwell time, with the system notifying the driver when the onboard power storage solution is completely charged. Equipment for the solution is located both onboard the vehicle and in cubicles located at stations.
The range of the vehicle's catenary-free operation is dependent on the capacity of the battery and Alstom says that in addition to its own vehicles the system is compliant with solutions from other manufacturers. Alstom has also worked closely with battery and supercapacitor manufacturers to develop SRS.
