Carmen is not sure: is Running the Motor of the electric Golf? Driving instructor Frank Löffler indicated on the Display in the dashboard. A graph shows that electricity from the battery to the E-flows in the engine. The driving lesson can begin. The 27-Year-old is not on the Gas and giggles: as sporty as the electric VW drives off, he looks even.
“The customers of tomorrow, you must explain the technique,” says instructor Löffler. E-cars to drive as an automatic car, only more dynamic. Under the sheet metal but almost everything is different than in the case of a Diesel or gasoline engine. “Tanking up with electricity, the drive, energy recuperation when braking are all part of the training,” says Löffler. Electric mobility is also in the driving school are still unfamiliar. – Carmen stops at an intersection, a car coming from the right. It is undecided. “What is also true in an electric car?”, ask Löffler and gives the answer himself: “Right.”
a ride to practice, students with a E-car, comes with tax collectors, the largest driving school, is rare. “The demand is very low,” says Harald Pohlmann, owner of the company with around 100 employees in Berlin, North Rhine-Westphalia and lower Saxony. Nevertheless, he has already recorded two years ago, three E-cars in the fleet. “We are facing a fundamental change,” says Pohlmann. “We’ll take care of this Innovation.”
No E-cars with trailer hitch
tax collector of many Bus and Truck drivers. In this Segment of electro-mobility is still exotic – and the technical hurdles are higher than for passenger Cars. Not only because there are hardly any vehicles. “We would like to use an E-Bus in the training,” says Pohlmann. “But where would I charge it?” The battery of the E-Golf can be refueled overnight at a Wallbox “full”, in the case of a large commercial vehicle this is not possible. Also, the trailer training with an electric car fails due to a banal fact: “There is no E-cars with trailer coupling,” says Pohlmann.

Little practice, in dealing with electric cars, the forces of the fire brigade. This can be for you and for injured persons in case of emergency, life-threatening. Because the firefighters in extinguishing the fire or salvaging does not work hazards that occur in accidents involving conventional vehicles, the power of up to 1000 volts and battery fires with extremely high temperatures.
on the Basis of a “rescue sheet”, which provides information on the electric drive and the components of the high-voltage system are also the employees of the Berlin fire brigade in the “identification query” trained. This means that you will learn where and how to defuse in case of an emergency, the E-car and the battery from the electrical system separates in the event that it was not the accident of an automatic shut-off is, for example, as the Airbags were triggered. Series vehicles are basically “intrinsically safe”, as the firefighters explained. “This means that several independent safety devices and shields are in place.” Thus, the separated high-voltage system is electrically isolated completely from the body. The thick, voltage-carrying cables are encased in fire red. A “danger to Persons by electric shock”, assured the fire Department, be excluded as a possibility “with high probability”.
batteries burn long
a Lithium-ion battery, however, Is caught in a fire, it can be elsewhere dangerous. Although water or special foam are also suitable in the case of burning E-cars to Clear, notify the fire Department. Because of the high temperatures and possible chemical reactions would have to but “are sufficient extinguishing agents reserves”. So it may take longer. Problems of the Lithium. It reacts with extinguishing water or other battery liquids, hydrogen, and ignites explosively. The fire breaks out so. However, the experts remain cool. “The Problem of very high temperatures is not to fight back for the fire, since light metals will find in the vehicle is used.”
body and life can go on elsewhere – for example, if in the Vehicle workshop for the repair of a electric car something goes wrong. “You should make to the high-voltage system, no errors,” says Daniel Kessler, a Car mechanic in the Volkswagen-branch in Franklin street. Otherwise it’s hot: Plus to ground, the POPs class. A workshop saying about incorrectly laid cable, which may be at 1000 volts voltage is deadly Serious.
Daniel Kessler has additional training as a high-voltage experts behind, in the Wolfsburg factory. He is so far the only mechanic in the Berlin branch, is allowed to disassemble, equipped with special gloves, safety shoes and helmet – a E – car battery. An electric is mounted to the car, cordoned off the area, additional warning signs indicate the danger zone. “So everyone knows who is doing what,” says Kessler. Two more colleagues are trained high voltage technicians, batteries and chargers, but are not allowed to disassemble. Four trainees prepare for the electric shaft, the roll according to the will of the VW group by the end of 2019/beginning of 2020 on the market. By 2025, the VW brand 20 want to have a pure – electric models in the program, and a Million a year to sell. It should then also be in the Berlin workshop, there’s more going on than it is today.
“industry is ready”
not far from the VW dealership from Mercedes builds at the salt banks of its great location for 50 million euros. Electromobility will be a Central area of, all sales, Service, and service offers of the new brand, “EQ” will be available in the future. For the Work on the high-voltage system, the operation is equipped and trained, the employees go through special training, such as on the topics of security, Voltage isolation, or diagnosis of high-voltage components. “Electric mobility is generating great interest,” says a spokeswoman. Among the technical measures, among other things, the special tools for Hybrid, Plug – In Hybrid and pure battery powered electric vehicles or fuel cells.

“The whole business is in the start-up,” says Dieter Rau, managing Director of the Automotive Guild of Berlin, with 400 member companies. He estimates that about 80 percent of the farms are well equipped in the Region of “good” for electric mobility. In 2013, the training regulation has been adapted according to the already coveted the occupation of motor Vehicle mechatronics technician got a new Dimension. How many Jobs in the Region by the technically far less complex E-mobility is in danger, is open. Nationwide, there could be up to the year 2035, according to a study by the Institute for labour market and occupational research (IAB), more than 100 000.
