Stop Guessing.
Start Knowing.

India's only independent EV Battery Forensic Audit. We reveal what your dashboard hides — and give you the physics to prove it to your OEM.

Your dashboard lies.
We don't.

OEM service centres have every incentive to keep you away from warranty claims. We have no such bias — we don't sell cars, we don't sell batteries. We only sell the truth.

🛡️
Peace of Mind

Know if your family is genuinely safe, your real-world range is accurate, and your battery performs as promised — not just what the OEM wants you to believe.

💰
Honest Valuation

Don't let a dealer lowball your resale value based on mileage alone. Our battery health certificate is the only third-party document that tells the full story.

Warranty Power

Use our forensic data to compel your OEM to replace a faulty battery module — not just "recalibrate" the BMS software and send you away.

We don't give you a number.
We give you the physics.

Cell imbalance detected in Module 3. Qualifies for warranty replacement under Section 4.2 of your battery warranty.
  • 📊
    Functional SoH vs. Dashboard SoH
    Your BMS is programmed to report an optimistic number. We apply the 5mV / 1% Penalty Rule to calculate your battery's real capacity under real-world load.
  • 🗺️
    Cell-Level Voltage Map
    We visualise every individual cell. A single failing cell causes Limp Mode, sudden shutdowns, and phantom range — invisible to your dashboard's averaged readings.
  • 🌡️
    Thermal Stress Test
    India's climate is brutal on battery chemistry. We test thermal performance under simulated peak load to identify cells that degrade faster than the pack average.
  • ⚖️
    Warranty Action Letter
    Our report is structured as a legal-grade technical document. Present it at your service centre to support a warranty claim — with data they cannot dismiss.

Know Your Battery.

Our technician comes to you. No garage visits, no waiting rooms. A full forensic audit delivered to your door — and your inbox.

The Science: Functional SoH
We apply a penalty for each millivolt of cell imbalance in your pack. A 5mV gap translates to real capacity loss that the BMS hides from you.
Functional SoH = Dashboard SoH − (Cell Δ × 0.2%)

Our mission is singular: to provide the most accurate, independent battery diagnostics in India.

We built The Honest EV because we saw too many owners being gaslit by service centres — told their batteries were fine, told range drop is normal, told to "just drive differently."

We disagree. An EV is a significant investment. You deserve to know what condition your battery is in — backed by physics, not platitudes.

No OEM affiliations. We don't sell cars or batteries.
Every report is generated from real OBD data, not estimates.
Reports structured to hold up in warranty disputes.
Models calibrated for India's unique climate and roads.
AI anomaly detection, reviewed by a human engineer.

They got the truth.
Then they got results.

Warranty Win
★★★★★

"My Nexon EV was entering Limp Mode at 20%. The service centre said it was fine. The Honest EV report proved a cell imbalance in Module 3, and I got a full battery module replacement under warranty."

★★★★★

"A dealer offered ₹3.5L below market citing poor battery health. I got the Honest EV audit — functional SoH was 91.3%. The dealer backed down immediately. Worth every rupee."

★★★★★

"As a fleet operator with 24 EVs, I needed to predict failures before they happened. The Honest EV API gives us cell-level data for the whole fleet. We've prevented 3 breakdowns in 4 months."
