The yellow line is the available solar power.
The gray area is the electricity consumption of the house. And the orange area here, that’s the Electric car charge. And although the days in March are still relatively short, the car was charged with 22 kilowatthours of pure Solar power. Sufficient for 120 Kilometers of completely climate-neutral driving.
If you want to charge an electric car with a wallbox, you need a special car charging cable. There are two different junction boxes here: Type 2: This is the system, which is usually used by the German manufacturers, as well as by Tesla Model 3 here: The junction that we have here.
The Asian manufacturers have a different system, which is called Type 1. A type 2 connector looks like this and the associated type 1 connector for Asian cars has a slightly different shape. I installed the cable from my wallbox, so that within a few seconds the charging process can start.
Done, that’s it. There are special holding devices for charging cables in specialist shops. If I want to start driving the car is ready to go in a few seconds. You can get in and drive off It couldn’t be more comfortable. You don’t need to go to the gas station for the full day, no more price comparisons.
Charging works here at home and essentially takes place at home. How quickly a car can be charged with a wallbox depends essentially on the charging power. And depending on the car it is quite differently. Cars with small batteries are usually charged in one phase.
With an output of 3.7 to a maximum of 7.4 kW. You can then recharge 21 or 41 kilometers in an hour.Some cars also tolerate higher charging power.
Then charging is three-phase, that means: In the cable there are three wires through which the power flows into the car. The charging power are between 11 and even a maximum of 22 kilowatts that are possible. And then we have 61 to 122 kilometers per hour that can be recharged.
Up to 1467 kilometers in twelve hours. There are no such big batteries and for private use at your own parking space such charging power is actually, already quite oversized. Yes, by the way: The higher the charging power, the shorter the lifespan of the car battery and the more expensive the wallbox in the end.
That means: you should carefully consider whether it is a good reasoning or not: to decide for an overcized wallbox because of >Reichweitenangst<. At the beginning you should really think about which charging power you really need. Than you can also safe a few euros in the end. Such a wallbox must be connected by the electrician.
The cables are thicker than a normal household socket. And the wallbox should also be registeredby the network operator.
