E-car: This is how charging and paying at e-car charging stations works

Charging stations for electric cars: questions and answers

How does charging at a charging station work?


That Charging an electric car works similar to that refuelingonly that electric charging takes significantly longer. The vehicle is parked next to the charging station and connected to the car and charging station with a cable and a plug each. The equipment usually has to be brought along; at some public charging stations, mostly fast charging stations, you only have to plug the permanently installed cable into the car. It is loaded either: a) by alternating current (AC = Alternating Current) with a type 2 plug (Mennekes) or a Schuko plug on a household socket; or b) by direct current (DC = Direct Current) with a CCS connector (CCS = Combined Charging System). The CHAdeMO plug developed in Japan is mainly used in Asia and the USA, but is slowly dying out in Europe. A normal charging point Outputs alternating current in the range of 3.7 to 22 kilowatts, which is converted to direct current by the vehicle’s onboard charger for charging the electric car battery.

A normal charging process with an electric car works like this: get charging cable, Open the charging socket on the e-car (usually on the front or where the tank opening is in combustion engines) and plug in. Then Unlock charging stationConnect the plug to the charging station. After loading in the same order remove the cable again. How fast the battery is chargeddepends on the charging station, the charging capacity of the e-car and the charging cable.

How do you pay at a charging station?


The most common methods in Pay at a public charging station are the by loading card (with invoice usually at the end of the month) or the via smartphone app (with direct debit). Payment by giro/credit card (with prior registration) or SMS (via prepaid or the electricity bill from your house provider) is also rarely possible. However, the new charging station regulation stipulates that all from July 1, 2023 installed new charging stations allow payment with at least one major debit or credit card.

Charging cards with a so-called RFID chip are usually held in front of a contact field on the charging station, and the app can be activated using a QR code on the charging station. Both methods usually have a previous one Registration required by the respective provider. There are about 300 of them in German-speaking countries. An alternative is the so-called e-roamingit allows you to pay with a charge card from multiple electricity suppliers.

Of the Tariff jungle in Germany is unfortunately still dense and confusing – this is ensured by the variety of flat rates (session fees), starting and basic fees, preferential tariffs or time-based billing, which even called the Federal Cartel Office into action. Since April 1, 2019, providers have actually had to have one at public charging stations Billing according to actually charged kilowatt hours enable. But there are still thousands of fast charging stations not compliant with calibration law. However, after consultation with the ministries, the calibration authorities of the federal states are still refraining from imposing fines so as not to jeopardize the expansion of the charging infrastructure.

What is Plug&Charge?


You can get there without a smartphone app, QR code or loading card Plug&Charge (“Plug in & charge”). With this system, the entire Loading and payment process automatically through Communication between charging station and car – from authentication to initiation to billing. The data is transmitted through encrypted communication, the system is considered secure. As is so often the case, the pioneer of the basic idea was Tesla, the standard ISO 15118 standard was developed jointly by charging point, roaming network and charging network operators as well as charging station manufacturers and car manufacturers. However, there is still right few electric vehicleslike the Porsche Taycan, the load with technology be able. Other manufacturers, such as Audi for the e-tron, are still testing.

How do you find the next free charging point?


Vehicle manufacturers, charging station operators and various Internet portals provide information on their websites or in apps about where the nearest charging station is – often also whether it is currently free or occupied. Many modern electric cars also have such a function built into the multimedia system.

How much does charging at a charging station cost?


Both Costs for charging there is sometimes significant price differences (Here is a price overview of several providers). In addition to the various payment systems, they are one of the biggest problems for the acceptance of electric cars in Germany. In 2020, the analysis agency EuPD Research determined in a detailed study that for a VW e-Golf the difference between the average and most expensive charging tariff is 90 cents per kilowatt hour (0.35 to 1.25 euros/kWh), which means additional costs of 1781 euros per year (2485 instead of 704 euros) means.
In many places, electricity at public charging stations is more expensive than household electricity, the green electricity provider Lichtblick found out in its 2021 charging station check (average value: 31.5 cents/kWh). Depending on the location and depending on the provider, there are still big differences. help with Finding the best contractDepending on individual driving behavior, the Mobilityhouse specialist portal can help. In the meantime, individual providers are increasingly demanding blocking fees for longer parking times at a charging station.

Which providers of charging current for e-cars are there?


providers are local and national electricity companies, some of which combine to form a national network. But larger electricity suppliers also offer charging electricity tariffs. at roaming solutions receive e-car drivers Access to the charging stations of several partners. Examples are Plugsurfing and NewMotion, which offer charging at almost all charging stations in Europe, as well as Ladenetz, Innogy, Hubject (especially for fast chargers on motorways), E-Charge (for ADAC members) and EnBW mobility+. For a fee, they take over the complete billing – payment is made according to the tariff of the charging station operator. Some car manufacturers such as VW and BMW also offer charging current tariffs, as well as the ADAC and the fuel supplier Shell (with “NewMotion”).

How many public charging stations are there currently?


The number of public charging points in Germany is until January 2022 according to the Federal Network Agency on exactly 52.203 has grown (of which 7,717 fast chargers and 44,486 AC charging points), which is an increase of more than 12,000 within a year. According to the ideas of the federal government, by 2030 one million charging points be available, for then – according to the goal – seven to ten million electric cars. According to the VDA, 2,000 new charging points would have to go into operation every week in the future – ten times as many as recently.

Especially in focus is the fast charging infrastructure. The mineral oil industry should by the end of 2026, three quarters of all filling stations with fast charging stations equip. Initially by self-commitment, rewarded with funding from a new aid package worth three billion euros. Are until the end of 2022 not a quarter of gas stations equipped, there should be a legal regulation. The state could thus oblige petrol stations to set up charging stations.

The number of public charging points is growing. But so far it hasn’t changed anything about the shortage. The number of registered electric cars is increasing three times as fast like that of the charging stations (as of April 2022). Instead of eight electric cars are currently coming 23 on a charging station. This is well below the requirements of the European Union.

What are fast charging stations?


fast charging stations are charging points with a Minimum power of 50 kilowatts (instead of 22 kW). In the also as DC charger designated devices is a Integrated rectifier, which converts the electricity and charges it directly into the vehicle’s battery. The best-known provider of superchargers is the electric car pioneer Tesla. Besides, there is High power charger with a Charging capacity from 150 to 350 kilowatt hours. Since charging electricity there is significantly more expensive, only about ten percent of the network in Germany (more than 24,000 stations) are fast charging stations. In addition, not all cars tolerate such a charging boost.
The federal government supports it public fast charging with a total of two billion euros. By the end of 2023, the so-called Germany network emerge: charging stations with several DC charging points 1000 locations200 of them on freeways. Charging capacities up to 300 kW must be made possible on site. The price per Kilowatt hour charging current should be a maximum of 44 cents amount, however, according to the tender, this is a “breathing upper price limit“, which can be adjusted to inflation and price developments on the electricity market.

Who is allowed to stand at a charging station for how long?


Only cars with an E license plate are allowed to park there (purely battery-powered vehicles or plug-in hybrids with a range of more than 40 kilometers or less than 50 g/km CO2 emissions). This is what the Electromobility Act (EmoG) says from 2015. The respective regulations regulate the details cities and municipalities. the length of stay is generally on the loading time limited, sometimes there is also a hour limit. Information about this is usually provided by the signage. If you load too long, you risk one blocking fee: It is automatically added to the charging fee debited. The rules are not uniform; EnBW, for example, cashes in after four hours ten cents a minute. The electricity supplier charges a maximum per charging process twelve euros blocking fee. It also occurs at night! E-car drivers should therefore definitely use the tariff regulations check. There is a threat of charging station blockers, whether e-cars or combustion engines 55 euros warning money or even the tow truck.

What do the car manufacturers offer when charging publicly?


Most manufacturers offer own loading services such as KiaCharge, Mercedes me Charge or BMW Charging. VW, Seat and Skoda operate the loading subsidiary Elli, which manages the loading. Audi, in turn, is at the Charge Now parent company DCS (Digital Charging Solutions) and is also planning its own fast charging network in cities. DCS shareholders are Daimler, BMW and BP. The DCS charging network currently includes more than 228,000 charging points in 32 countries.
