Know exactly
what your Tesla
actually costs.
VoltMate reads every charge and trip straight from your Tesla and turns it into one clear number — home, Supercharger, public and free, priced at your local rate. No spreadsheets. No guesswork.
Charging costs, finally clear.
Every session is classified automatically — home, Supercharger, public or free — priced at your local $0.15/kWh rate and grouped into a monthly picture you can actually use.
Where your charging spend goes
Home and public sessions, split and summed in real time.
Auto-classified by source & tariff.
Priced where you charge
Health, range and climate at a glance
VoltMate shows your Tesla's live state without opening official menus or pulling out your key.
Every mechanism, working.
The same systems VoltMate uses to capture telemetry, classify charging, tag trips, guard privacy and report on fleets — shown live. Try the toggles.

Bring your history
Pull past trips & charges from spreadsheets or Tessie, then tag and export them like everything else.
A logbook your accountant will trust.
Tag trips as business or personal as you drive. VoltMate builds IRS-aware records ready for review and export — PDF or CSV, handoff-ready, with privacy built in.
Run the whole fleet from one screen.
Assign company Teslas to drivers, watch live telemetry, track logbook completion and export fleet-wide reports — with structural driver privacy that never exposes personal trips.
Structural, not a switch
Admin reports show completion and cost — never a driver's location or personal trips.
See what you'd save.
Slide your weekly driving and pick where you charge. VoltMate shows the gap between petrol and electric at United States rates.
Estimate only. Petrol car at 30 MPG / 7.8 L·100km, Tesla at 0.28 kWh/mi, against your selected charging rate and local fuel price. Your real numbers live in the app.
Up and running in one charge cycle.
