GOLDI Mobility’s new GOLDiON H18 bus will run on both hydrogen and electricity, offering long range, extended warranty and competitive pricing.
Developed under the GOLDiON project, the bus is designed to use a charge depleting strategy for the battery, draining only electricity. The battery is discharged until it reaches a minimum state-of-charge.
When the state-of-charge level is reached, a charge sustaining strategy is then engaged and the state-of-charge is maintained. The fuel cell is used to help propulsion and to provide additional energy to maintain the battery state-of-charge.
With its advanced energy management system, the powertrain efficiency is fully optimised by considering both zero emission technologies which are taking part in propulsion.
The bus can be refuelled at a high flow rate from a hydrogen station like other hydrogen buses. Furthermore, its plug-in technology allows the battery to be re-charged from an electricity outlet.
Commenting on the vehicle, Ferenc Kovacs, CEO, GOLDI Mobility said, “We are pleased to offer such an advanced articulated bus that can be driven, both by hydrogen and battery- truly zero-emission each.”
The entire project was supported by Hy-Hybrid energy who performed an extensive market analysis before selecting the key components and drivetrain technology.
As a result, the GOLDiON H18 was selected to be designed as a special plug-in hybrid with battery and fuel cell drive.
Dr. Naveed Akhtar, CEO of Hy-Hybrid Energy, added, “We decided to take the best out of the two zero emission drivetrains, i.e., battery and hydrogen fuel cell, and the result was GOLDiON H18.”
“With an optimised operating strategy, this combination offers maximum efficiency, dual-energy propulsion and extended range over currently available state-of-the-art fuel cell electric buses, battery electric buses and fuel cell range extender buses.”
