Electricity for charging e-cars: four ways to charge e-cars

A vehicle with a combustion engine needs petrol or diesel – and an electric car needs electricity. What sounds banal is a challenge for many e-beginners or discourages them from buying. Because it is an important question for anyone planning to buy an e-car: Where do I get it after I buy it Electricity for my e-car or my plug-in hybrids? Which charging type has which advantages? And what do I have to pay attention to when charging e-cars?

1. Charging at the Schuko socket

First of all, the most common power source: the power outlet. Many homeowners have one on the outside wall Schuko socket installed, for lawn mowers or electric hedge trimmers. Now the new electric car is parked next to it. So just grab the can, right? The unequivocal advice: only at a socket that is clearly suitable for this, preferably only after being checked by an electrician. The usual 230 V sockets are on the promotion one much smaller amount of electricity (2.3 kilowatts of continuous output at 10 amps; possible are up to 3.7 kW at 16 A).

A domestic Schuko socket is only an emergency solution when charging e-cars.

The loading take not only Long (six to 24 hours), there is also the risk of the socket and the cable in the wall heat strongly. In the worst case it exists Fire hazard, possible damage is not automatically covered by the building insurance. Only those who want to supply their electric vehicle with power for a few kilometers a day, for example to commute, should use the socket. And: who absolutely with one extension cable need to load should make sure the cable enough cross section for the desired amount amp has it completely rolled out is and not with humidity comes into contact. After all, charging at the socket is particularly gentle on the car’s battery due to the slow speed.

Power socket only conditionally suitable

An alternative, though not a good one, is one CEE-16 socket, even Camping or building electricity connection called. Here with up to 400 volts high voltage current loaded. Although it can keep up with a so-called wallbox (see below) in terms of charging power and thus charging speed, there are certain dangers here too (e.g. overvoltage) and certain requirements must be met (correct cable / charging box / adapter; network operator informed). If the worst comes to the worst, we recommend a separate supply line protected by a residual current circuit breaker (FI / RCD).

2. Charge at home with the wallbox

Wall boxes for charging at home are not only fast and secure, they are also promoted.

The best way to Charging at home is clear a wallbox. She is charging an electric car five to ten times faster on than a household socket. Such a home charging station usually has 11 or 22 kW charging power and must be installed by a specialist company (in six steps to the wallbox). They are a big advantage costs. In the normal house electricity tariff, the kilowatt hour usually costs significantly less than at a public charging point. And best of all: the state is responsible for the purchase and installation funded with 900 euros per charging point (This is how you get the grant). Incidentally, not only homeowners or apartment owners, but also tenants have a chance to have their own charging station (there are five inexpensive wallboxes with subsidies). If you then have another Photovoltaic system on the roof, you can charge for free.

Charging at work has many advantages

What many do not know: Many employers enable charging at work, albeit rarely for free. It is true for an employee with an electric vehicle no legal claim on a charging option at work, but more and more employers are setting up one or electrify equal the whole Company car fleet. Especially since this can also have advantages for companies and not every employee needs their own charging point. The free or discounted charging of electric or hybrid vehicles in the employer’s business is according to § 3 No. 46 EStG tax free (if the employer uses the power granted in addition to wages). this applies for private and company cars – and by the way also for him monetary benefit when a company charging device is provided, i.e. when the home wallbox belongs to the employer. For drivers of electric company cars there is also further tax advantages.

3. Public charging points in the tariff jungle

Strengths and weaknesses of public charging stations

Many public charging stations now have green electricity, but they also have many weaknesses.

Now for the public store. The Association of the Automotive Industry (VDA) regularly demands more support from the state, and organizational skills and planning are sometimes required for a longer journey. And yet: something is happening in the German one Charging station landscape. According to the Federal Network Agency, were in this country on July 1, 2021 38,876 normal charging points and 6493 fast charging points (altogether 45,369) in operation, plus some not reported. All electric car drivers have a charging option here – in theory. In practice there is still quite a bit impenetrable tariff jungle (Guide to Germany and Europe). Payment is made by charging card or app, and a prior contract is usually required. You can only charge your e-car for free on certain occasions, for example when shopping or eating.

4. Fast charging on the go: Tesla, Ionity, Fastned dominate

Ionity operates Europe’s leading high-power charging network.

The ideal solution especially for travelers Fast charger. However, the electricity is more expensive here and can only be used with the appropriate battery management in the car (DC charging). Above all, Tesla pilots with their 25,000 superchargers around the world are fine. Come since 2019 Supercharger V3 with a peak power of 250 kW is used, on which a Model 3 can recharge a range of 120 kilometers in five minutes. A further increase in output to 300 kW is planned. Another market leader is Ionity, an amalgamation of VW, Daimler, BMW, Ford and Hyundai, which operates 400 charging parks with an average of six on long-distance travel routes in northern, central and southern Europe HPC chargers (High Power Charger; charging power up to 350 kW) want to equip. The Dutch provider Fastned also wants to expand further in Germany.

Street lamp charging

Almost too good to be true: charging at the street lamp has long been technically possible.

In the meantime, exotic solutions such as fast charging on street lamps are technically possible, but there is obviously a problem with the approval. And more and more petrol station chains like Aral expand their offer, sometimes even with Ultra-fast chargers. Because at some point, so much seems to be foreseeable, there will be no more cars with internal combustion engines that need petrol or diesel, but only electric cars with electricity.
