One of the questions other people ask me frequently is how much does the electricity for an EV cost per 100km?
There is a different answer for ev electricity costs for each person as it varies greatly depending on where you drive and where you charge.
My Tesla 3 long range EV uses 15kWh each 100km, so here are examples of electricity cost in eastern states, as at March 2024.
| Sample AC/DC Rates at Mar 24 | c/kWh | $ per 100km (15kWh) |
| Solar/ToU AC | 0-15c | $0.00-$2.25 |
| Res.GeneralRate | 27c-38c | $4.05-$5.70 |
| AC free dst charge* | 0c | $0.00 |
| AC paid dst charge | 15c-60c | $2.25-$9.00 |
| Everty DC | 30c-60c | $4.50-$9.00 |
| Chargefox DC | 30c-92c | $4.50-$13.80 |
| Tesla DC | 40c-78c | $6.00-$11.70 |
| Chargebay DC | 55c | $8.25 |
| Jolt DC* | 0c-49c | $3.92-$7.35 |
| Evie DC | 50c-73c | $7.50-$10.95 |
| NRMA DC | 54c-65c | $8.10-$9.75 |
| BP Pulse DC | 55c-65c | $8.25-$9.75 |
| Elanga DC | 65c | $9.75 |
| Elu DC | 67c-70c | $10.05-$10.50 |
| AmpCharge DC | 69c | $10.35 |
* Jolt first 7kWh free. Many dest. chargers are free. Above is sample only, see full list of charge networks.
Fast charging costs
I was asked what the cost of providing a fast DC charger like a Tesla Supercharger is and I don’t know. I’m not sure what proportion of costs electricity is for a Supercharger. I don’t know how much Superchargers cost to build, install, connect, maintain and operate and what the standing demand charges are, but I expect the price of electricity is a minor input to their costs. The Tesla Superchargers near me are in leased space in a shopping centre car park. The centre is owned by AMP Capital and I expect the monthly lease of that space would be very high and not related to energy prices either.
