AVANCITY+ S HTB
Avancity+ S HTB is a trolleybus based on Skoda electrical traction system with independent running mode provided by a diesel auxiliary power unit allowing equivalent performance either on electric mode or on sections not covered by wire.
The trolleybus design does not differ from that of Avancity+ S bus, the only visible difference concerns the assemblies on the roof. On demand, the roof unit can also include supercapacitors modules capable of storing most of energy generated during braking. The stored energy is returned to the traction motor during acceleration, both in electric mode or autonomous running with a better efficiency in electricity and fuel consumption.
