Hydrogen bus
The TriHyBus chassis, power electronics and traction system is based on the concept of Škoda Electric trolleybus. The main source of energy is hydrogen PEM fuel cell (about 50 kW). Secondary sources are lithium-ion traction battery and supercapacitors.
Compressed hydrogen is used as a fuel. It is stored in the bus roof extensions in four high-pressure composite vessels with a total volume of 820 l. The maximum pressure is 350 bar. There are about 20 kg of hydrogen when fully loaded.
Sophisticated control system was developed for the cooperation of all energy sources. It optimizes the energy flows and allows efficient energy recovery to secondary sources when driving downhill, slowing and its re-use in energy-intensive modes such as accelerating or driving uphill.
Beyond the normal board indicators there is a MMI interface, which brings together control, visualization, and security features associated with hydrogen propulsion. In the passenger area there are also two screens, which visualizing energy flows in the current drive of the bus.
