How to charge a 1-phase car at home?

Is that a problem! 1-phase home charging is basically a bit challenging. Or slow down. This is due to the fact that even in the best case, 16A of power can be taken from one phase of the home socket, and even then it must be ensured that the socket can withstand taking that maximum current for several hours straight. Namely, even if the fuse lasts, the socket may not last.

Let's assume that the outlet is a super-schuco model and can handle the maximum current. Converted to power, it (16A x 230V = 3680W) makes about 3.7kW. In one hour, the car's battery accumulates only the amount of energy needed to travel twenty kilometers. For example, the popular fully electric car Hyundai Ioniq with a 28kW battery and single-phase charging charges from empty to full, taking losses into account, in about eight hours. Overnight is not a problem here, but if the trip needs to be continued during the same day, the power of the single-phase home charging can become a bottleneck. Namely, the Ioniq would be able to receive 6.6kW of charging power from one stage, if such was available.

A 3 x 16A power charger is also not useful in this case, because even in them the power obtained from one phase remains at 3.6-3.7 kilowatts. The only advantage over the Suko charger is that you don't have to worry about the durability of the socket when connecting to a power plug.

However, there is a solution! Namely, a masterpiece of domestic engineering, the Walle 25A. Thanks to the transformer technology, the device in question can use three phases, and increases the power of one phase up to 6 kilowatts, or about 25 amperes. This is already close to the maximum charging capacity of any single-phase electric car. And because the Walle 25A uses all three phases evenly, it does not unreasonably burden the home's electrical network or main fuses.
