I m participating at an EV car evaluation by Swiss Emobile. Here is my data for the month of february:
Zoe: Km: 1173, kWh: 245, kWh/100Km: 20,86, Energy cost for 100 Km: 4CHF04
Tesla: Km: 723,2, kWh: 137,1, kWh/100Km: 18,95, Energy cost for 100 Km: 3CHF67
The Zoe was driven little bit faster. The price for the energy is only theoretical because I charge the cars mostly on public charging stations which are free.
The cost for 100 Km with our car with combustion engine is 18CHF17.
Even if we had to pay for the energy for charging our electric cars, we save every month ca. 290 CHF, or every year: 3480 CHF.
