Charger plug type not correct

[thibaultmol]

This is a problem that's been annoying me a lot and I think I mentioned it in dm's but not in a proper issue:

When you use the charging theme. make a theme and select for example

8 vehicles can be charged here at the same time

and then one plug type.

Then it's safe to assume to suggest that plug type should be atleast 8, not 1 as it's currently always set.
