Introduction to charging stations
Switching to an electric car is a big step—and it also means choosing the right home charger, often referred to as a wallbox. But what exactly is a wallbox, and what should you look for when buying one?
A wallbox is a charging station for your EV that’s mounted on a wall—for example in your garage, on a carport, or on an exterior wall. It charges your car faster, safer, and more reliably than a standard household socket. A normal socket isn’t designed to deliver high power for many hours at a time. A wallbox, on the other hand, includes:
The charging power (measured in kilowatts, kW) determines how quickly your car is charged.
Charging time for an EV with a 60 kWh battery (from empty):
| Charging source | Charging power | Charging time (100%) | Charging time (approx. 80%) |
|---|---|---|---|
| Household socket (230 V, 10 A) | approx. 2.3 kW | ≈ 26 hours | ≈ 21 hours |
| Wallbox (11 kW, three-phase) | 11 kW | ≈ 5.5 hours | ≈ 4.5 hours |
| Wallbox (22 kW, three-phase) | 22 kW | ≈ 2.7 hours | ≈ 2.2 hours |
If you have a PV system on your roof and an EV in the driveway, you’ll ideally want to connect the two. Because what could be better than charging your car with self-generated solar power? In principle, it’s quite simple: the PV system generates electricity, which is fed into your home’s electrical system via the inverter. A compatible wallbox detects when enough PV surplus is available and then automatically starts charging.
For this, you need three things:
Wallboxes offer many additional options, such as:
Depending on the features, wallboxes usually cost between €500 and €1,200. In addition, there are the electrician’s installation costs, which depend on the scope of work. Some wallboxes require a dedicated RCD (residual current device), while others already have this protection built in.
Connecting your PV system to a wallbox isn’t rocket science. With the right technology and a bit of planning, you can charge your EV conveniently, affordably, and climate-friendly at home—and become much less dependent on electricity prices.
