On August 29, 2016, Gunnar Schneider, head of municipal sales at ENSO, ceremonially presented the Faculty of Electrical Engineering and Computer Science at Zittau/Görlitz University of Applied Sciences with a fully electric Nissan Leaf 30 kWh vehicle for its use.
“We will use the vehicle primarily for trips between our two main campuses in Zittau and Görlitz,” said Professor Klaus-Dieter Haim, Dean of the Faculty of Electrical Engineering and Computer Science.
This vehicle, equipped with a special direct-current connector (Chademo), will also be used to investigate the possibility of feeding electricity back into the power grid and to assess the role such a vehicle can play as an emergency power source for private homes.
In addition to reducing air pollution in metropolitan areas and decreasing dependence on oil and gas, electric mobility can also help stabilize the power grid. As fewer and fewer conventional power plants maintain the balance between generation and consumption following the energy transition, consumers that can be switched on and off quickly, as well as electrical energy storage systems, are essential for stable grid operation.
To achieve all these goals, not only are smart grids necessary, but also a suitable communication structure between the grid and electric vehicle charging stations, as well as data collection and processing that is acceptable to users.
At present, however, many questions regarding electric mobility remain unanswered: How can electric cars help support the grid? How many electric cars can a grid accommodate, both with and without grid expansion? What charging infrastructure is needed, and how can billing be kept simple? How great is the potential (e.g., second cars or fleet vehicles)? How will users respond to changes in usage conditions? And much more.
The faculty and ENSO are certain of one thing: electric vehicles are the future of mobility.
Technical specifications of the Nissan Leaf 30 kWh motor:
| Motor | Electric motor with 80 kW power and 254 Nm torque |
| Energy consumption | Approx. 15 kWh / 100 km (combined) |
| Battery | 30 kWh |
| Charging time | Schuko (230 V AC / 10 A / 2.3 kW) 13 h (100%) Type 2 (230 V AC / 16 A / 3.6 kW) 7 to 9.5 h |
| Type | (400 V AC / 16 A / 6.6 kW) 5.5 h (100%) |
| DC | (Chademo) (50 kW) 30 min (80%) |
| Range | max. 250 km (according to NEFC) |
| Top speed | 144 km/h |
| Purchase price | Starting at 34,385 euros (including battery) |
ENSO procured the vehicle for the University, as well as additional electric cars for municipal and regional partners, through a funding program from the Federal Ministry of Transport and Digital Infrastructure (BMVI). These partners can gain two years of experience with the vehicles and thus serve as ambassadors for electric mobility in the region.
ENSO operates 15 charging stations in its service area, two of which are in the Görlitz district. In Oybin and Neusalza-Spremberg, depleted batteries can be recharged. All charging stations are listed at www.stromticket.de/ladestationen .
By the way: The vehicle is also intended, of course, to promote forward-looking technologies and the many interesting study opportunities at Zittau/Görlitz University of Applied Sciences.
