Run a real route. The EV does not always win.
Type your car, or just the litres. Real-world figures, not lab ones.
Worked example: Berlin to Munich on the A9, 585 km. A Model 3 Long Range against a petrol car at 6.8 L/100 km, on live Supercharger prices.
One charge does not cover this trip, and it does not need to.
75 kWh at 20.5 kWh/100 km on the motorway. Driving 80% down to 10%: above 80% fast charging crawls and below 10% you are hunting for a plug, so seventy per cent of the pack is what goes under the wheels between stops. The dashed circle on the map.
Berlin to Munich along the A9.
Reality: The trip runs past a single charge, so it splits into one stop. About 18 minutes plugged in. That is the whole of the range problem on this route.
17 Supercharger sites sit on this one corridor.
294 stalls, every one 250 kW and open to any brand
366 km between charges
Sites you could still reach on the charge you left with
Reality: 8 choices for the one stop. Density is not the constraint on a corridor like this — the surplus is what lets the planner choose on price, and what makes a missed stop recoverable rather than a problem.
Two stops, 35 minutes plugged in, on a five-and-a-half hour drive.
Reality: 30 minutes. That is the honest gap on this route, and both stops land where you would want a break anyway.
Same route, same day. Electricity against petrol.
Savings: €41.08 on 585 km, 47% cheaper. The Superchargers are priced live, so the planner charges where the kWh is cheap rather than wherever you happen to stop.
Pick your cars and your cities, and get the same breakdown.
