At least here in Finland electric cars use the same taxation method as Diesel called "käyttövoimavero" which roughly translates to "usage power tax". This is based on weight so 0,015€ per day per 100kg. On top of that there is the "car tax" which is based on emissions which for electric cars is at the minimum which comes at 106€/year.

One thing I am sure of is that once the amount of electric vehicles starts to rise they will just up the "käyttövoimavero" (or come up with a new one) to make up for the lost tax revenue.
