I too took a mini holiday with wife in my small EV this summer, but across Northern Germany. I also found out that with going for free chargers at malls when available, my cost in total for electricity was 1/3 of what it would have cost in gasoline. I also charged at a camping ground and even a harbour, sitting in the car for 5 hours in heavy rain.
This very same trip in our previous petrol Citigo cost us about €32 so basically this was only ~12 euros cheaper. In the winter, it cost us about double the cost of travel in the petrol Citigo (€67-68). But more than 90% of all our driving is around our home city or within 50-60km from it, so our total costs per 100km is still only €2.38, over 11.000 km. At home we average about €0.5-0.9 / 100 km due to mostly free charging.
