in Germany more and more shopping malls and supermarkets offer free charging points on their parking places. In my direct neighborhood (within 10Min ride) there are two. Both are equipped with 2 parking places at one tripple charger (50kW CCS, 50KW Chademo & 43kW type 2). For a typical shopping tour between 20-40 minutes I will get 15-25kWH for free . For our Model S that is approximately 100km of range.
Yesterday‘s free charging result
That’s really a good deal. For sure I prefer those shopping centers to others - now that I’m riding a BEV.
