Why EVIQ?

Most EV companion apps — including manufacturer-issued apps — are excellent at what they were designed for: showing you the current state of your vehicle. Today’s range, today’s charge level, today’s cabin temperature.

What they don’t tell you is the trajectory — the aging curve of the most expensive component in your car. Owners typically only learn they have a degradation problem when the projected range has dropped 15–25% from new, at which point they may already be past the point of the warranty replacement threshold.

EVIQ closes that gap by turning telemetry your manufacturer already agreed to share (via the official Tesla Fleet API today, more OEMs coming) into six analytical products your default EV app doesn’t provide:

Every EV battery loses capacity as it ages. The question is how fast — and whether your pack is aging faster or slower than expected.

EVIQ computes three degradation views:

• Instant slope — the past 30 days, adjusted for temperature. A slope 4× above the baseline is a red flag we surface as an anomaly.
• 12-month curve — usable-capacity trend line versus your vehicle’s day-one EPA capacity, plotted against fleet median for your vintage.
• Lifetime trajectory — projected State-of-Health at 5, 8, and 10 years, back-tested against thousands of similar vehicles.

Tesla’s battery warranty replaces packs that fall below 70% of original capacity within 8 years or 100,000–150,000 miles (depending on model). Most owners have no idea whether their pack is on track to cross that threshold before their warranty expires.

EVIQ shows you three numbers most EV apps don’t:

• ETA to 70% crossover — climate-adjusted, based on your degradation slope.
• Projected State-of-Health at warranty end — so you know whether you’ll qualify.
• Miles-of-headroom — how many miles you can drive before you burn the warranty window.

If EVIQ projects you’ll cross 70% before your warranty expires, the app tells you the earliest defensible date to file a claim — with the evidence pack ready to print.

“Why is my range 40 miles less than when I bought the car?” is the most common EV owner question — and it almost never has a single answer. EVIQ decomposes range loss into five attributable causes:

• Cell wear — irreversible capacity loss from lithium-ion aging.
• Calibration drift — reversible, corrected by a full 0→100 charge cycle.
• Phantom drain — vampire loss from Sentry Mode, Cabin Overheat, etc.
• Temperature — seasonal loss you’ll get back next spring.
• Driving pattern — Chill vs. Sport, average speed, HVAC habits.

Each category comes with a specific, quantified recommendation.

How you charge is the single biggest lever you control over how fast your battery ages. EVIQ analyzes your charging history and gives you a personal profile:

• Supercharger vs Level 2 ratio vs the fleet median.
• Time spent above 90% SoC — a known accelerator of aging.
• Nights parked at 100% — the biggest offender for most owners.
• Precondition-in-winter compliance — a common Model S/X blind spot.
• Optimal charge window — matched to your utility’s off-peak schedule.

EVIQ Intelligence™ produces a natural-language narrative for your pack: what the anomaly detector saw, what it means, and the two or three actions worth taking. Every claim in the narrative links back to a specific number on your dashboard — nothing is invented.

The AI is a translation layer over deterministic math — not the other way around. You always see the numbers underneath.

Every subscriber can generate a one-tap PDF designed for a Tesla service advisor. It includes:

• Your VIN, model, and current EVIQ Score.
• State-of-Health with date-stamped measurement history.
• Flagged anomalies, plotted against the Tesla warranty threshold.
• Projected 70% crossover date and its confidence interval.
• Citations to the underlying telemetry timestamps.

Owners who’ve used the report say it converts “my range feels off” into a service-advisor conversation that ends with a work order.

Not a replacement — a complement. Here’s the honest breakdown:

“Other EV apps” refers to the typical manufacturer or third-party companion apps EV owners use day-to-day. EVIQ is independent and not affiliated with any vehicle manufacturer.

• Long-term owners who plan to keep the vehicle past year 5.
• Owners approaching warranty end who want to know whether they qualify for a replacement.
• Owners about to sell or trade who want an independent, third-party health report to defend their price.
• High-Supercharger users who want to understand what their charging profile is costing them.
• Owners in extreme climates — Phoenix summers, Minnesota winters — where degradation math is very different from Bay Area norms.
