DRIVING INTO THE FUTURE

Electric drive units play a central role in the transition to emissions-free mobility; however, converting a fleet to ebuses presents transportation companies with a number of challenges.

 

Although electric cars are still the absolute minority on the roads, commercial vehicles powered by alternative fuels are already well-established in many areas. The ever-increasing demand for reduced emissions in inner city areas has resulted in a spike in interest amongst transportation companies in vehicles with drive systems that are especially environmentally friendly.

 

 

However, converting their fleet to battery-powered electric vehicles often presents operators with unforeseen challenges. “Those who prepare meticulously for the introduction of eBuses in advance and who plan extensively for this will be able to overcome those challenges,” asserted Stefan Sahlmann, Head of Transport Solutions at MAN Truck & Bus. The new MAN Transport Solutions consultation service provides support to transportation companies and fleet operators during their transition to alternative drive systems, addressing all issues concerning drive technology, route network planning, route optimisation and battery management. After all, these factors have a significant impact on both route planning and internal processes and schedules.

 

Anyone switching to eBuses should take particular care to ensure that the correct conditions are present in terms of depot management, power supply, maintenance and staff qualifications. “Alongside the charging station infrastructure, other factors at the depot, such as its size, security and parking situation, play an important role,” said Sahlmann. It is also important that its power requirements are determined. This will depend on the number of eBuses and the charging strategy that is to be used.

 

“Consideration should also be given to storing energy locally. Through the use of additional generators or energy storage units, significant reductions can often be made with regard to energy costs, as energy requirements can be fulfilled during times at which the network is not being used to capacity and when the cost of electricity is therefore cheaper,” explained Sahlmann. Charging and energy management are therefore of significant importance to eFleets.

 

MAN Truck & Bus has been actively involved in placing alternative drive systems in city buses for a number of years now and aims to reduce the emissions produced by the public transportation system to a minimum. Its portfolio has included city buses with natural gas engines for many years; thanks to their use of natural or synthetic gas, these are practically emissions-free. In addition, since 2010, the MAN Lion’s City Hybrid has been offering an alternative that is interesting from both an economical and an ecological point of view. It will be joined by fully electric buses in the near future.
