Daimler Buses has introduced an expansion in the usage scenarios for the Mercedes-Benz eCitaro fuel cell, with a new operating mode allowing electric buses to operate exclusively on hydrogen as the sole energy source. This development presents a solution for transport operators requiring high daily ranges without the ability for intermediate charging. The eCitaro fuel cell boasts a long range of up to 600 kilometers, significant recuperation benefits, and high drive power, making it suitable for urban traffic and challenging terrains. It features a 60 kW fuel cell as a range extender, complemented by a 295 kWh battery. The introduction of the 'H2 mode' operating strategy ensures that the fuel cell intelligently manages energy supply to the drive and batteries, maintaining optimal State of Charge without external recharging. The fuel cell now offers three operating strategies - Maximum Range mode, Balanced mode, and H2 mode, catering to varying energy requirements and driving conditions. Daimler Buses provides comprehensive eMobility ecosystems and system consultants to assist in selecting the most suitable operating strategy, enhancing efficiency and reliability for transport operators.
