Medha group’s (Enika) Hydrogen Bus project completed a significant milestone by commencing its passenger service in Gdańsk in early May 2024. Gdańsk is a port city on the Baltic coast of Poland. Enika is the bus system integrator and have designed, manufactured and integrated all power electronic and control devices enabling optimal operations.
The Hydrogen fleet known as Nesobus can travel around 450 km on a single tank with refuelling taking just 15 minutes. Average daily distance urban buses travel in Gdańsk is around 250 km. Another 10 new Hydrogen buses will join the fleet this year.
Braking resistor: The RBTD.60kW.2R5-19920 braking resistor is essential for managing the bus's kinetic energy during braking.
Drive auxiliary box: The ENI-AUX_BOX/K3 houses various electronic components and controls for the drive system.
Battery current sensor: The 24V ENI-BCM board battery current sensor monitors the battery's performance.
Communication supervisory system: The ENI-VCCU SWITCH.3 system ensures seamless communication between the bus and the charging infrastructure, complying with ISO 15118 and DIN 70121 standards.
Charging visualization system: The CCS2 ENI-VCCU DISPLAY.1 system provides real-time information on the bus's charging status.
Hydrogen cell DC/DC converter: The ENI-PH2/70 converter efficiently converts DC power from the hydrogen fuel cells.
Diagnostic connector: The ENI-P3CANv3 diagnostic connector allows for easy troubleshooting and maintenance.
Hydrogen cell handling devices: Enika has also provided necessary devices for handling and managing the hydrogen fuel cells.
Medha group’s expertise in electric vehicle systems has been instrumental in the successful integration of these components into the Nesobus hydrogen buses. As a system integrator, Medha has ensured the seamless operation of the entire drive system, enabling the buses to deliver exceptional performance and efficiency.
Medha group’s hydrogen buses are paving the way for a cleaner and more sustainable future. By replacing traditional diesel-powered buses with hydrogen fuel cell vehicles, we can significantly reduce greenhouse gas emissions, improve air quality, and create a more environmentally friendly transportation system. Hydrogen buses offer numerous advantages, including zero tailpipe emissions, reduced noise pollution, longer operating ranges, and faster refueling times compared to electric buses powered by batteries. As cities and countries seek to transition to cleaner forms of energy, hydrogen buses are emerging as a promising solution for public transportation.
