About EVIQ

Give every EV owner an honest, science-grounded view of the single most expensive component in their vehicle — the battery — so they can charge smarter, drive further, sell higher, and claim warranties earlier.

Modern electric vehicles carry the equivalent of a $20,000 battery pack whose health silently degrades over years. Owners are given a range estimate on the dashboard, but not the underlying diagnostics that would tell them whether today’s state-of-charge is normal for their vehicle’s age, climate, and driving pattern — or a red flag that will one day trigger a warranty claim.

Manufacturers understandably keep that intelligence proprietary. EVIQ closes the gap by combining the data an owner has already authorized the manufacturer to share (via the official Tesla Fleet API), peer-reviewed Li-ion aging science, and modern AI narrative, into a single dashboard the owner controls.

The EVIQ Score™ is a proprietary 0–100 composite of four sub-scores:

• State-of-Health — usable capacity vs new EPA capacity.
• Degradation trajectory — 30-day slope adjusted for temperature and cycle count.
• Anomaly load — presence of five classes of Tesla battery-management “blind-spot” patterns (phantom drain, cell imbalance, thermal excursions, calibration drift, precondition inefficiency).
• Warranty margin — climate-adjusted ETA to the 70% capacity threshold that triggers Tesla’s battery warranty replacement.

Every number in the app is traceable back to a measurable signal from the Tesla Fleet API. Nothing is invented. Nothing is guessed. And when there isn’t enough data to compute a value confidently, we say so.

EVIQ is an independent application that utilizes the Tesla Fleet API after owner authorization. We are not affiliated with, endorsed by, or sponsored by Tesla, Inc.

When you connect your Tesla to EVIQ, you authenticate directly with Tesla using Tesla OAuth. EVIQ receives only the read-only vehicle scopes you approve. See our Security and Privacy pages for the specifics.

• Owner-first. Your telemetry is your telemetry. We build the product to answer your questions, not to sell you something.
• Read-only, always. EVIQ never sends commands to your car. No unlock, no drive, no honk, no summon.
• No data sales, ever. We don’t sell your data. Not to insurers, not to advertisers, not to anyone.
• Explain the math. Every score in the app links back to the raw signal that produced it, so you can audit us.
• Ship weekly. Small, well-tested improvements every week — not annual mega-releases.

EVIQ is a small, independent team of engineers, EV owners, and battery scientists based in the U.S. If you’d like to say hi, reach us at support@eviq.pro — a real human reads every message.
