E-Bus in Graz, Austria

Fast-charging supercaps are the main source of energy for environmentally friendly electric buses in Graz. They carried passengers on the Graz lines from November 2017 until October 2018 as part of the initiative from Graz Holding, holding test operations for a one year duration to find a green innovative transport solution for the future.


Statements from Dipl.-Ing. Andreas Solymos, Graz Holding:

“The test operation shows that supercaps are technically well suited to operate city bus traffic without emissions. Particularly noteworthy is the feature of the supercaps to be charged with high currents in a very short time, which results in short standing times at the charging stations.”

“Our Chinese partners were always giving their best to support the project in the best way possible. Certainly, we also faced some linguistic and cultural challenges sometimes, but all of these have been mastered. The representations of CRRC in Europe played an important role at this part.”
