Hours long Wait at the pillar: The Charging of E-vehicles deters buyers. A consultant argues that gas stations in the future, change batteries, offer and reap the harvest of mockery. The work abroad.

Long hours of Waiting at the charging station? Only to filled with batteries to continue the journey? How pointless is that? Much easier it would be if every gas station in Germany alone there are more than 14,000 – including exchange batteries for electric cars would offer. A change in three minutes, and more.
Just as the current systems consultant Ralf Dunker from Hamburg-the future of electric mobility. To focus on charging stations, in his eyes, no sense and a waste of public Park space. “Removable batteries, to allow the driver to have a virtually infinite range, and he always has the latest battery technology on Board,” says Dunker, the municipalities in energy advises.
Dunker is deeply entered into the process chain and to operators of exchange stations, even a lucrative business model. His Plan: The Oil companies to invest in replacement batteries and replacement stations at their gas stations and are intended to be the “driver and not the blocker” of the turn.
Mercedes is contrary to Dunker
The Foundation form according to the Dunkers idea of renewable energy from Wind and solar plants. They are subject to natural fluctuations. The more wind turbines and solar panels there are and the bigger their share of the energy mix, the greater the fluctuations in energy input. In a lot of Wind, especially at night, the wind turbines will be laid today – partly against payment – still, or the surplus electricity abroad give away. Energy is politically and economically unacceptable.

Dunkers business idea comes in here. Approximately 200 to 300 change batteries on a 14,000 gas stations could be used as a huge buffer, you would. in his opinion, a rule energy capacity of around 60 gigawatts At the current stock is bought at surplus production power is cheap and at peak times for high demand, sold at a higher price. “The unavoidable current fluctuations through the use of renewable energies to be a model for business and are not a Handicap,” says the energy expert.
Jürgen Schenk is skeptical. The idea of changing batteries, the head of electric mobility Mercedes-Benz believes is nonsensical. “The battery modules should be standardized in width, depth, and in the voltage position, but we would not have the freedom to switch the cells parallel or serial. Not to mention warranty and liability issues.”
“That would be a planned economy”
Investigations of Mercedes had not shown that a change of batteries to fit to the usage profile of the customer. According to the Stuttgart-based group, 90 per cent of the car amount to journeys less than 400 km. “50 weeks in the year the motorist is driving less than this distance,” says Schenk, “and even if he may lead once more, would be for the highways, rapid charger with 100 kilowatts of power charging from all.”
Also his colleague at BMW, the battery expert Peter Lamp, holds a standardisation of the battery packs is unrealistic. “That would be a planned economy. In addition, much to many batteries would need to be stocked, far more than there are electric cars,” says Lamp.
The idea of removable batteries is not new. The former SAP Executive Shai Agassi founded in 2007, Project Better Place, a company that wanted to establish the infrastructure for the exchange of batteries. But with Renault, a car manufacturer was ready with a Better Place to work. In 2013, the Start-up filed for insolvency proceedings.
Toyota is planning models with removable batteries
But times are changing. Diesel scandal and the threat of driving bans increase the pressure on the corporations to bring more models with alternative drives on the market and to test new technologies.
Only recently it became known that Toyota is one of the largest automobile manufacturers in the world, plans to invest in rechargeable batteries. According to the Japanese broadcasting company NHK Toyota engineers City-electric cars want to equip with relatively small battery capacity with such systems. The first stations will be at the dealers installed later would cover a network of swap stations all over Japan. With a mass manufacturer such as Toyota, this idea could learn a new swing.
Niche projects, there are already some. So, the Chinese Internet billionaire William Li for its electric SUV Nio ES8, which was presented a few months ago in Beijing, intends to build, within the next two years of over 1100 stations. In this country there are first models, the Dunkers idea to follow. A three-seat Mini should be equipped-vehicle of ACM (Adaptive City Mobility) with eight replaceable batteries. The City-E-Taxi is still in the approval process, but already requests. “The Indian government sees the exchange of battery technology as a key issue for the rapid expansion of E-mobility,” says project initiator Paul Leibold.
The replacement batteries have bags the size of four milk
In Taipei and now also in Berlin, the company Gogoro delivers with their scooters daily to the proof that the technology can work in everyday life. About 50,000 customers change in Taiwan’s capital, day-to-day a total of more than 33,000 Times the energy storage of more than 500 stations. The replacement batteries have bags the size of four milk, weighing nine pounds and have a capacity of 1.3 kWh. Two batteries fit under the seat of the scooter, they are replaced in less than a Minute and provide energy for the next 90 kilometers. In Berlin, the still-young electric scooter-Service Coup of Bosch, an E-Scooter Sharing, on the two wheels of the brand Gogoro.
