You mean the chargers? Yes. Typically based on speed. So a 50 kw machine might charge you 21 cents whereas a 250 kw machine might be double that. Also sometimes depends on the time of day. Eg, middle of the night might be 14 cents kwh even on a 250 kw machine.
We charge mostly at home at 9 cents per kWh but after a certain amount of kWh in a month it jumps to 14 cents…ish. Plus tax etc etc.
Tesla superchargers are more common. This is a pic of us stopped at a supercharger in Kamloops. This one was at the welcome centre. Even has a sani dump. Handy as a last stop when coming home from a camping trip.
Most super charger stations have 12 to 24 chargers. Some have 100. This one is in hope we like it because it has trailer stalls on the one side. That and a great coffee and bran muffin place
Cheers.
