New York City und Berlin machen es vor: Wie Flottenmanager mit Elektroautos Kosten sparen

Munich, July 22nd 2019 

It’s news like this that is inspiring increasing numbers of fleet managers to switch their fleets to electric cars: The city of New York has published the maintenance costs of its fleet vehicles and revealed the enormous potential savings delivered by electric cars.

The lowest costs are achieved by the purely electric Chevrolet Bolt, available in Europe as the Opel Ampera-e, with a converted value of 183 euros per year. Two more electric cars, the Nissan Leaf with 306 euros and the Ford Focus Electric with 344 euros in annual maintenance costs, are among the top savers in the New York City fleet. 

At the other end of the scale, classic combustion engine cars generate all kinds of annual costs: The Ford Taurus, a model in the upper mid-range, results in average annual costs of 821 euros, while the combustion version of the Focus generates costs of 1,607 euros, more than four times as much as the Focus Electric. For hybrids and plug-in hybrid, the city of New York calculated annual maintenance costs of between 442 euros and 1167 euros.

A recent study by the International Council for Clean Transportation (ICCT) reaches a similar conclusion: The non-profit organisation has compared the costs of different VW Golfs, which is available with a petrol engine, a diesel engine, as a plug-in hybrid and an electric model, in multiple EU countries. According to the study, here in Germany, the VW e-Golf costs around 1,400 euros less during the first four years than a petrol car with similar features and performance, and up to 4,000 euros less than a diesel model.

This experience is shared by transport companies in Berlin. In the recently completed eMobility Scout project, they concluded that electric cars are cost-neutral from the fourth year onwards. This is one reason why Berlin’s main public transport company, BVG, plans to switch its entire fleet of 325 commercial vehicles to electric by 2025.

Investments that pay off

Although the operation of purely electric vehicles requires an initial investment in charging infrastructure, even these expenses are kept down with the right resources. The technology company The Mobility House, with many years of experience in this field, knows exactly how to keep the costs for the mains connection and different charging options as low as possible: Their charging and energy management system can be connected to the charging infrastructure of different manufacturers via public interfaces to monitor the charging park and prevent expensive peak loads. This avoids unnecessary costs during installation and achieves high savings during operation.

The system from The Mobility House controls the charging processes so that all the electric cars are supplied with energy, without overloading the connection to the power grid. To achieve this, the charging processes are automatically spread or offset across a period of time. Vehicles that require more energy because they travel long distances or only have brief downtimes can be charged preferentially. The eMobility Scout project also identified a charging and energy management system as an important component in switching to an electric fleet.

The charging and energy management system has already proven itself in practice for many customers. Like the Mainzer Stadtwerke (public works department of Mainz), for example, who recently installed 70 charging stations in its underground parking garage. Cost savings of up to 80,000 euros resulted simply from avoiding unnecessary expansion of the mains. In addition, controlled charging will deliver potential annual savings of up to 50,000 euros in ongoing operation.
