ICE cars retain 55 to 65 percent after three years. EVs retain 40 to 55 percent. The difference is battery trust, not mechanical condition.
EV Resale Value Intelligence
Price every used EV on verified battery health, not guesswork. Battery resale scores, charge cycle history, and QR verifiable certificates that buyers actually trust.
The used EV market in India runs on suspicion
India's first wave of mainstream electric vehicles is now entering the secondary market. Nexon EVs, Tiago EVs, and MG ZS EVs from the 2020 to 2023 model years are now hitting used inventory across dealer lots and marketplaces. Buyer interest is real, but so is the hesitation.
Used internal combustion cars often retain 55 to 65 percent of original value after three years, while used EVs commonly land closer to 40 to 55 percent. That gap is rarely about paint, tyres, or suspension. It is mostly about one unresolved question: what condition is the battery really in?
The battery pack is the highest-value component in the vehicle. Until it is measured and verified, every offer becomes a discount for uncertainty.
The battery pack alone can account for up to 40 percent of an EV's total value. Pricing the car without verifying the pack is pricing in the dark.
India still has no mandatory battery State of Health disclosure at ownership transfer, so dealers and buyers are left to interpret incomplete data.
Battery verified resale, end to end
Navionyx is the verification and pricing layer the used EV market has been missing. We do not estimate. We measure. Our plug-and-play diagnostic device reads the BMS directly, runs a guided test cycle, and produces a resale score that holds up under buyer scrutiny, finance review, and insurance underwriting.
Every certificate carries a QR code that any buyer can scan from any phone. No login. No app install. Just verifiable proof that the price is backed by battery evidence.
Battery Health Resale Score
A single pricing score backed by State of Health, usable capacity, voltage response, cell balance, thermal stability, BMS status, regen behavior, and estimated real-world range.
Full Vehicle Usage Profile
See total kilometres, daily usage pattern, driving style indicators, and operating context from first deployment onward.
Charge Cycle and Degradation Trend
Track cumulative cycles, fast-charge ratio, and the actual degradation curve instead of relying on a single battery percentage.
Buyer Confidence Report
Give buyers a plain-language summary with rating, expected range, and warranty transfer clarity they can understand instantly.
QR Verifiable EV Certificate
Every report carries a unique certificate ID, QR code, digital signature, and live verification status for tamper-evident trust.
Dealer Dashboard for Inventory
Manage certified stock in one place with bulk testing workflows, listing badge exports, marketplace integrations, and white-label options.
The dashboard range number is not the answer
Most used EV listings still rely on one of three weak signals: the dashboard range estimate, the seller's verbal claim, or a basic OBD scan that returns a single State of Health percentage. None of those is enough for serious pricing.
The dashboard range varies with driving style, weather, traffic, and route shape. The seller claim cannot be audited. And a single State of Health percentage only tells you something about remaining capacity. It does not tell you whether the battery is stable, balanced, or likely to trigger thermal or fault issues.
A battery can show 85 percent State of Health and still be risky because of imbalance, fault windows, or abnormal thermal behavior. Another battery at 78 percent can remain stable and useful for years. Resale pricing needs to separate those cases clearly.
The Navionyx resale score combines State of Health with seven other measured battery signals to produce a number that can survive buyer negotiation, dealer scrutiny, and finance-team review.

Measurable resale outcomes, not promises
Faster sale cycles on certified used EV listings compared with uncertified inventory.
Higher realized resale value on vehicles backed by a Navionyx EV Certificate.
Buyer trust uplift reported by dealers after introducing certified listings.
Reduction in post-sale battery-condition disputes when a verified certificate is attached.
Average certification time per vehicle from device plug-in to certificate generation.
Every certificate is QR verifiable with real-time status visibility and no login requirement.
How this connects to the rest of the Navionyx platform
This resale workflow is strongest when it is attached to a live battery history. That is why it connects naturally with Predictive Maintenance for EV Fleets, where degradation trends and alert histories are captured long before a vehicle reaches second life.
For buyer trust and seller proof, it sits beside the Navionyx EV Battery Certification process. For broader operational visibility, it can also sit inside the EV Fleet Management platform so resale and remarketing decisions use the same lifecycle data already collected in service.
If a business needs a full trust stack, this solution also complements the AI dashcam page for driver-behavior visibility and the Navionyx platform overview for white-label dashboards and API integrations.
For used EV marketplaces and dealer groups, the result is a cleaner buyer story: vehicle history, battery verification, and certificate proof all tied together in one operational layer instead of scattered across vendors.
