Skeleton Technologies has received a contract from Medcom to supply ultracapacitor energy storage for the tram network in Warsaw, Poland.
Ultracapacitors have a capacity of one million cycles and immediate charging. This allows for functions that are not possible using batteries, which have a capacity of only 2,000-3,000 cycles.
Trams with these ultracapacitors installed will be able to use recovered braking energy for acceleration. They will also protect Warsaw’s grid.
