Performance Analytics

Battery Degradation Matrix

Tesvian actively monitors every charging session and daily drain. Our algorithms map nominal full pack energy against temperature variances to calculate true battery health, eliminating the guesswork of estimated range.

  • Continuous capacity tracking (kWh)
  • Charge curve optimization
  • Vampire drain detection

Drive Logs

Total efficiency tracking. Map elevation changes, speed profiles, and HVAC usage to understand exactly where your energy goes.

Charge Economics

Micro-level cost tracking. Input custom TOU utility rates and map Supercharger invoices to generate complete tax-ready expense reports.

Sentry Automation

Location-based rule engine. Automatically enable Sentry mode at high-risk locations and turn off at home to prevent vampire drain.
