The H110 plugs only handle up to 13A/3Kw (or less kW on some plugs if you go by some of the reviews on Amazon) would think that was below what you'd need for an electric car charger. Having a quick look around the smallest 2 or 3 chargers I found were 3kW and 16A. Also even if there are 13A/3kW chargers to be had they would quickly overwhelm these plugs and they'd shutdown with thermal overload.
Best option for that would be one of the DIN rail relays I would have thought. Think they handle way more than 3Kw with some handling up to 65A at 240v (so around 15kW) though to be fair I don't know enough about electric cars to be sure. At least then if you decide to put one of the 7kW chargers in you're covered.
