Actively shaping future mobility is also a core topic for VHH; anyone who uses local public transport has already made the right choice – after all, taking the bus is sustainable. “Our customers expect that we as companies implement modern, sustainable technologies, such as electric buses, and also that we test it thoroughly,” states Toralf Müller, Managing Director of VHH. “We are very grateful that the German Federal Ministry of Transport and Digital Infrastructure (BMVI) also supports this project – it again emphasises the public interest in examining all aspects of e-mobility, from the perspective of responsible sustainability.” In the case of re-using batteries, multiple advantages can be exploited.
Different scenarios are tested using the large storage system, in order to optimise power consumption at the VHH depot. This includes improved utilisation of the network and cushioning of peak loads when charging electric buses (peak shaving). Alexander Adler, responsible for the second use energy storage system project at MAN Truck & Bus confirms this: “With the peak shaving method, the storage system can reduce up to 600 kW of peak load, and thereby lower the costs when using electricity.” Additionally, the project partners anticipate new findings on the ageing behaviour of the batteries, on efficient battery management and on the life cycles of future battery technologies.
Verkehrsbetriebe Hamburg-Holstein GmbH, which is head-quartered in Hamburg, employs over 1,600 people and provides transportation for over 100 million passengers a year. The fleet comprises of approximately 560 buses, which are to be converted to electric drive in the coming years. VHH will test the first electrically driven city bus from MAN in day-to-day operations at the beginning of 2020 – the company formally received the MAN Lion’s City E in the Hamburg “Speicherstadt” warehouse district in mid-December. Another 17 additional MAN vehicles for the VHH fleet will follow at the end of 2020.
Testing of the second use energy storage system is taking place as part of the mobility partnership between the Free and Hanseatic City of Hamburg and the Volkswagen Group – which MAN is also part of. The partners are working together on innovative solutions, in order to make urban mobility safer and more environmentally friendly, reliable and efficient.
