Electric cars: loading is not fueling

2019-09-09T18:50:27.768Z

VW introduced the ID.3, an electric car for the masses. For his success will be important how fast the battery is full. That depends on many factors.



Charging a battery-electric car takes ten seconds. So at least the proponents of this drive argue - and just mean the plugging and unplugging of the cable. The compulsive break in between can be miserable. How long the trial will actually be depends on different factors. It's complicated. The only thing is clear: shop is not fueling.

Getting used to the characteristics of a battery-powered car will be a challenge for thousands of motorists in 2020 with the ID.3. Volkswagen introduced him on Monday evening and hopes that the model after the Beetle and the Golf will be the next classic. 30,000 copies are already paid, according to VW. The Wolfsburg have the ID.3 a standard for this price range technology package given: You can choose between three battery sizes with 45, 58 and 77 kilowatt hours (kWh) storage capacity.

How far can you get that? Regardless of the legalRichichweitenangaben is at Richtrichtgeschwindigkeit on the highway with a power consumption of 20 to 25 kilowatt hours per 100 kilometers to be expected. On federal and rural roads and in the city should probably be around 15 kWh. Translated, this means that if you only use your electric car for a tour to the nearby city, as a children's shuttle or for shopping in the supermarket, you may have to reload only once a week. If you are planning another trip, the route must be planned carefully.

Sometimes you load five times as fast for a small extra charge

How fast a car charges, depends mainly on the charging power. It is expressed in kilowatts (kW). As a rule, modern battery-electric cars have two maximum specifications: one for alternating current (AC for short) and one for direct current .

Example Volkswagen ID.3: It can take eleven kW on the AC side. In purely mathematical terms, eleven kWh are in the battery in one hour. A typical size for a car in this segment. The charging station for home, called Wallbox (about 1,500 Euro), can offer this performance without any problems. The autointernal chargers, however, are costly. The manufacturers like to save on it: Volkswagen builds in the basic version of the ID.3 only 7.4 kW of power. Opel is doing the same with the Corsa-E. In the higher equipment, it is eleven kW. A Smart EQ generates 4.6 kW and 22 kW at an additional cost of 840 euros - so it is almost five times as fast and therefore more practical. And a Jaguar I-Pace has a very large battery, but can charge for money on the AC side not more than 7.2 kW.

How quickly it progresses is often of secondary importance when it is charged with alternating current. When the electric car is parked overnight in the garage or on the company car park during the day, it can leisurely draw electricity. This also protects the battery. On a big vacation trip the needs are exactly the opposite. Now an involuntary break can be agonizing. Users therefore place a high value on fast charging columns that deliver direct current (DC). And if possible as much as the car can handle.
