2026 Policy Intelligence

EV Battery Warranty
Claims Masterclass

In 2026, a warranty is no longer just a "year count." It's a technical battle involving SoH logs and Battery Aadhaar tracking. Here is how to ensure your ₹7 Lakh asset is protected.

MoRTH Battery Pack Aadhaar (BPAN)

As of January 2026, the Indian Government mandates a 21-character Battery Pack Aadhaar Number (BPAN) for all EVs. This digital passport records every thermal event, fast-charging cycle, and degradation log.

How to Win a 2026 Warranty Claim

1

The "15-Day Rule"

Do not leave your EV at 0% SoC for more than 15 days. Modern BMS logs record "Deep Discharge" events, which are the #1 reason manufacturers reject 2026 claims.

2

The "AIS-156" Visual Check

Before your 80,000 km service, check for underbody dents. Under AIS-156 Phase 2 standards, even a 5mm casing deformation can void your warranty.
