Track every cent you spend charging your Tesla — at home, at a Supercharger, or anywhere else — using your actual Australian electricity tariff, not a rough estimate.
How it works
Enter your electricity retailer and rate in Settings. VoltMate supports flat-rate, peak/off-peak, and time-of-use tariffs. Most popular Australian retailers pre-loaded.
When your Tesla starts charging, VoltMate opens a session. It records kWh added, charger type, location, and duration — no manual input needed.
Cost is calculated using the energy added multiplied by your actual tariff rate, adjusted for time-of-day if you're on a TOU plan. Accurate to the cent.
What you get
Separate out what your Tesla is adding to your electricity bill each month — down to the session.
Supercharger sessions logged with kWh added and Tesla's per-kWh rate automatically applied.
See your total charging spend by month and compare trends — useful for budgeting and FBT calculations.
VoltMate automatically calculates your running cost per km — the ATO-required figure for logbook claims.
Track every charging dollar with Australian tariff accuracy.
