Why battery health matters
Every Tesla continuously streams telemetry — pack voltage, cell-balancing data, charge and discharge cycles, and thermal readings. On their own these numbers are noise. Aggregated and modelled over time, they tell a precise story about a vehicle's true state of health.
Car Pulse Tracker reconstructs that story. We read the verified service history, the charging statistics, and the battery diagnostics, then project the expected capacity curve for the months ahead.
What the report reveals
- State of health (SoH): estimated usable capacity versus the original rated capacity.
- Degradation trend: how quickly capacity is fading, normalised for climate and usage.
- Charging behaviour: the share of fast-charging sessions and their thermal impact.
A healthy pack degrades slowly and predictably. An anomaly in the trend is an early warning worth acting on before a resale or a long trip.
Follow these steps to generate your first vehicle report.
How the system works
Car Pulse Tracker connects directly to Tesla's official Fleet API to pull real-time and historical data from your vehicle. The process takes under 4 minutes. No account creation required, no subscriptions, no recurring charges.
1. Select your vehicle brand
Choose Tesla from the brand list. Car Pulse Tracker currently supports all Tesla models: Model 3, Model Y, Model S, and Model X.
2. Connect your Tesla account
Click "Connect to Tesla" and you'll be redirected to Tesla's official login page (auth.tesla.com). Sign in with your Tesla credentials and approve the requested data permissions. Your Tesla username and password are entered only on Tesla's website — we never see or store them.
3. Complete your payment
Once connected, you'll see your vehicles. There is a single flat price of €6.99 (VAT included) per report — no plans to compare, no subscriptions. We accept credit cards (Visa, Mastercard), Google Pay, and Apple Pay.
4. Your report is ready
We pull your vehicle data directly from Tesla's Fleet API. Every report includes:
- Battery & range — Current level, usable battery, rated/estimated/ideal range
- Battery State of Health (SoH) — The key degradation metric from Tesla's partner-level endpoint, plus battery capacity in kWh
- Charging state — Current charging status, charger type, charge limit
- Charging history — Up to 24 months of Supercharger sessions with downloadable invoices and CSV export
- Tire pressure (TPMS) — All four positions with warnings
- Alerts — Categorized by type: charging, tires, driver assist, and other
- Software — Installed version, pending updates, and firmware release notes
- Vehicle configuration — Color, trim, wheels, interior, driver assist features
- Warranty — Active coverage, expiration dates, and odometer limits
- Factory options & specifications — Equipment codes, option names, and technical specs from Tesla's partner endpoint
Your report is also available as a downloadable PDF. You can download individual charging invoice PDFs, download all invoices as a ZIP file, or export the charging history as a CSV file.
Reading the projections
Treat the projection as a range, not a single number. Telemetry-driven estimates improve with every charging cycle we observe, so the more history a vehicle carries, the tighter the confidence band becomes.
