W what would actually what if there was a huge rush for e-cars from now on? The answer is simple: Then, in one fell swoop, even more e-car owners would be faced with the dilemma: Where should I charge my locally emission-free steel environmental activist? And what does it actually cost me?
Private charging and with the employer

He's off the hook E-car owner who has a private charging option in the form of a garage with power supply or even a wallbox. The average price per kWh of household electricity is 29.4 cents. With a battery capacity of 41 kWh (Renault Zoe), 12.05 euros would be due. A range of 100 kilometers costs 4.12 euros. Commuters who can charge at their workplaces are also well-rounded.
Public charging stations
The rest of the people rely on public charging stations, the charging capacities of 11 kW, 22 kW, 44 kW (fast charging station ) or 135 kW (Tesla Supercharger). There have even been 350 kW charging stations for commercial vehicles since March 2018. However, the actually usable charging power depends on the receiver. There are currently 7,343 charging stations in Germany, i.e. almost 15,000 charging points (most charging stations have two plug connections), freely accessible to everyone. Among other things, the exact location, the charging strength and the current charging situation can be checked on site using a smartphone application. What unfortunately no app shows is the parking situation in front of the charging station. And since there are not parking bans for conservatively powered vehicles in front of every charging column, the column may not be used, but the parking lot may be occupied.

Payment models at public charging stations
If a free space has been found, the charging process should actually start, provided that the charge can also be paid for. And it is precisely at this point that the e-car owner enters the currently unbelievably confusing tariff jungle. On the one hand, this is due to the often non-transparent tariff structure. On the other hand, on the different payment models. There are prepaid or postpaid models, models with a basic fee and reduced kWh price, time tariffs, charge quantity tariffs, flat rate tariffs or start-up fee tariffs.

In Germany alone there are currently more than 300 providers of charge cards. To put your mind at ease: Most charging stations offer several payment models at the same time, so that even emergency chargers that normally charge at home and now have to charge their e-car unplanned can cope. Sometimes it is even sufficient to state the credit card. However, it must be clear that this type of emergency charge is financially painful. Around five euros per hour on an 11 kWh column can be called up quickly in an emergency.
Whoever chooses which payment model therefore depends, in addition to driving behavior (distance covered during the day), primarily on the region in which the e-car driver is staying. In regions like Cologne and the surrounding area, charging at 22 kW RheinEnergie charging stations is currently completely free. Current! 'In theThat will change over the course of the year, ”reveals a RheinEnergie spokesman. A call to the local electricity provider is therefore worthwhile for everyone and can sometimes lead to positive surprises.

Different city, different tariff structure
If there is no free pillar available for frequent travelers, a card with or without a monthly basic fee and a reduced kWh price or even a flat rate is possible. The differences between the kWh prices can easily vary between 55 and 0 cents. At EnBW, charging at an AC charging station costs a maximum of one euro until February 28, 2019 - two euros for quick charging with DC. From March 1st, EnBW will be calculating the electricity that has actually been charged at its approximately 25,000 charging points. The basic fee-free standard tariff is 39 cents /kWh at AC or 49 cents /kWh at fast charging stations and high-power chargers (HPC). For a monthly basic fee, which is due from the fourth month onwards, frequent chargers receive a reduced kWh price (29 cents AC, 39 cents fast charger and HPC).
Stadtwerke München (SWM) are offering a monthly basic price of 10.12 euros charging with your card at their charging stations for 1.80 euros per hour. The time calculation begins when the charging process starts and only ends when the charging plug is disconnected from the column. What at first glance seems like a huge cost trap is only intended to ensure that fully charged Stromer clears the charging station for those following as quickly as possible. By way of comparison: EnBW politely asks its customers to vacate it quickly after loading. If you don't stick to it, you will receive a message via smartphone app. “We know the problem and don't want to put e-mobilists under unnecessary pressure. But we observe whether it really works, ”explains Marc Burgstahler, who is responsible for electromobility at EnBW.
Frequent drivers need a lot of operator cards or a roaming card
If the electric car driver prefers to travel across regions, an e-roaming charge card is ideal, which can be used anywhereworks and more and more often has an RFID chip for contactless payment. One of the oldest and therefore best-known providers of roaming cards is NewMotion. The company was founded in 2009 and offers payment options at over 70,000 charging stations in 25 countries. In the meantime, over 116,5000 charging cards are registered with them. There is no basic fee here.
'The costs for a charging process at a public charging station depend on the respective operator. They can vary depending on the charging station. The price is usually calculated from a basic fee (per charging process), a volume tariff (per kWh) and the charging time (per hour), ”the company says. In Stuttgart, for example, the charging minute costs seven cents, regardless of whether the charging station pumps 3.7 kW, 11 kW or 22 kW per hour into the Stromer. It is of course only logical and very advisable to take the maximum power consumption into account when purchasing a vehicle.

But even within NewMotion there are payment mode differences Small interim calculation: Let's stay with the Renault Zoe with its 41 kWh battery - and for the sake of simplicity, for the sake of simplicity, as an exception, most charging stations charge the battery up to 80 percent at maximum power and then continue to charge it more slowly to save the battery. To fully charge a completely empty Zoe in Stuttgart, the costs at one and the same charging station can range between 24.42 euros (3.7 kW, 11.08 hours), 15.65 euros (11 kW, 3.73 hours) and 7 .83 euros (22 kW, 1.86 hours) vary. In Essen, charging costs 22.96 euros (41 kWh at 56 cents each), in Munich (1.19 euros basic charge per charge plus 48 cents per kWh plus 2 cents per minute) between 23.10 euros (22 kW) and 34 , 17 euros (3.7 kW). Depending on the local tariff model, there are huge differences at first glance.
Telekom customers pay from 29 cents per kilowatt hour

Also the Telekom offers a central billing service for drivers of electric cars. So far, Telekom charging power has been offered, which will become the new Get Charge brand at the beginning of April 2019. Telecommunications customers can tap electricity at 13,400 public charging points. The activation and billing takes place here too via a smartphone app or a charging card, the RFID chip of which acts as a key.
Prices vary depending on the local provider. However, Telekom promises 5,000 charging points from one of its 'preferred partners', including Innogy, Ionity and the Dutch company Fastned. Here, Telekom customers pay 29 cents per kilowatt hour for a charge with alternating current, while quick charges with direct current cost 39 cents per kilowatt hour. At the other charging points, the kWh price is a uniform 89 cents.
Shopping and charging for free at the same time
Good news for everyone who is responsible for shopping at home: Free electricity cannot be used only keep regional electricity providers ready, but also supermarkets and furniture stores. Kaufland announced 100 fast charging stations by 2019, and another 50 by the end of 2020. Aldi Süd has 80 charging stations (28 of which are fast chargers with 50 kW) and IKEA plans to equip all 53 locations in Germany with charging stations by 2019.
