Decode Your EV Battery’s 21-Digit Code Instantly
Enter the BPAN printed on your battery label to verify manufacturing date, chemistry type, and safety rating. Works for Tata Nexon, Ola S1, Ather 450, TVS iQube, and all Indian EVs.
Type or paste your 21-character code. Spaces and hyphens are stripped automatically.
Three Reasons to Check Your Battery
Your battery is the most expensive component in your EV. Knowing its age, chemistry, and origin protects your investment.
Prevent Fire Risk
Identify if your battery uses NMC chemistry. NMC cells generate more heat than LFP in India's summer temperatures above 40°C. Knowing your chemistry helps you take the right precautions.
Verify Resale Value
Buying a pre-owned EV? Sellers routinely misrepresent battery age. The BPAN manufacturing date reveals the actual age (not the vehicle age), so you pay the right price.
Warranty Claims
Most manufacturers offer 5 to 8 year battery warranties. The BPAN manufacturing date is the official proof of age for warranty claims at authorised service centres.
What This Tool Can (and Cannot) Verify
The 21-digit BPAN is an identity specification based on MoRTH draft guidelines. It reveals manufacturing specifications, not live internal cell health.
What BPAN Can Verify
- Exact Manufacturing Date: Month and year of pack assembly (reveals if a used EV has an older or swapped pack).
- Cell Chemistry: Identifies NMC, LFP, or Sodium-ion chemistry for thermal safety precautions in Indian summers.
- Pack Architecture: Nominal system voltage and usable capacity in kilowatt-hours (kWh).
- Assembly Origin: Registered country code of assembly and certified fire safety extinguisher class.
What It Cannot Verify (Limits)
- Live State of Health (SOH %): BPAN is a static identifier. To estimate capacity wear based on age and charging habits, use our Used EV Battery Health Estimator.
- Cell Imbalance or Thermal Damage: Does not reflect whether previous owners abused fast charging or overheated the pack.
- Physical Pack Integrity: Cannot detect underbody impact fractures, water ingress, or internal connector corrosion.
- Official Warranty Acceptance: Warranty approval requires an authorized OEM service center diagnostic scan. If out of warranty, estimate replacement expense with our Battery Replacement Cost Calculator.

Solving specific EV ownership and pre-purchase questions across India:
Where Is My BPAN Code?
The BPAN is a 21-character code printed on the battery pack label. Here is how to find it on your vehicle.
Electric Scooters (Ola S1, Ather 450, TVS iQube)
The battery label is under the floorboard or inside the removable battery compartment. On portable-battery models, check the sticker on the side of the battery unit itself.
Electric Cars (Tata Nexon EV, Tata Tiago EV)
Check the battery label in the boot area, near the charging port housing, or in the owner manual. The BPAN may also be on a sticker inside the door jamb.
Reading the Code
The code looks like: MY008A6FKKKLC1DH80001.
It is 21 characters. Ignore spaces or dashes on the label when entering.
QR Code Option
Many battery labels include a QR code alongside the BPAN. Use the Scan QR Code button in the decoder at the top of this page to scan it directly with your camera.
Frequently Asked Questions
BPAN stands for Battery Pack Aadhaar Number. It is a unique 21-character alphanumeric code assigned to every electric vehicle battery pack in India. The system was proposed by MoRTH in September 2025. The number is assigned by the battery producer and encodes chemistry type, capacity, voltage, manufacturing date, and cell origin.
The BPAN reveals the battery chemistry type. LFP (Code E) batteries are more thermally stable and considered safer in high-temperature environments. NMC (Code F) batteries offer higher energy density but require more careful thermal management. A battery older than 5 years should be tested at a certified service centre to assess its State of Health (SOH).
EVCheck.in is an independent private tool, not affiliated with MoRTH or the Government of India. The decoder logic is based on the publicly available draft BPAN guidelines (September 2025). Since the regulation is in draft stage, manufacturer codes are not yet mapped to public company names. Chemistry, capacity, voltage, and manufacturing date results are accurate per the draft specification.
NMC (Nickel Manganese Cobalt) provides higher energy density meaning more range per kilogram, but is sensitive to heat and overcharging. LFP (Lithium Iron Phosphate) offers lower energy density but is significantly more thermally stable, has a longer cycle life, and degrades more gracefully. For Indian conditions (high ambient temperatures, frequent charging), LFP is often more practical for daily use.
If your code is not exactly 21 characters, the battery may have been manufactured before the BPAN regulation was implemented. You may also have misread some characters. The BPAN system excludes visually ambiguous characters like I, O, Q and the digit 0 in specific segments. Contact your EV manufacturer or dealership with the code from the battery label for official clarification.
Is your battery past its prime?
If the decoder shows your battery is more than 5 years old, it may have degraded below 70% capacity. Get a cash offer from certified recyclers before it degrades further.
