Maharashtra Introduces Digital Battery Passport for EVs – A Big Step for Better Resale and Transparency

Follow us here:

India is moving fast towards electric mobility, and Maharashtra has taken a big and smart step for EV owners. On 23rd May 2025, the Maharashtra government launched a Digital Battery Passport for Electric Vehicles. This new initiative is a part of the updated Maharashtra EV policy 2025, and it’s a game changer for anyone looking to buy, sell, or own an electric vehicle in the state.

But what exactly is a battery passport? Why does it matter? And how will it help you as a buyer or EV owner? Let’s understand it all in simple words.

What is a Digital Battery Passport for EVs?

A battery passport is a digital document that keeps track of all the important information related to your EV’s battery. It’s like a health report or service history for your vehicle’s battery. It includes:

• Manufacturing date and details
• Battery health status
• Charging and discharging history
• Diagnostics and performance data
• End-of-life condition

This information will be available in real-time and can be accessed by buyers, sellers, insurers, and service centres. Think of it like checking the service history before buying a used petrol or diesel car but now, for EVs, it’s even more detailed.

Why This Matters – Key Benefits for Indian EV Buyers

Currently, if you want to buy a second-hand EV, you have to trust what the seller says about battery condition. But with this battery health passport, you’ll get verified data, which builds buyer confidence.

Here’s how it helps:

• Better Resale Value: Buyers will pay more if they are sure the battery is in good condition.
• Fair Insurance Premiums: Insurers can check battery usage and give you a better rate.
• Informed Decisions: No guesswork while buying used EVs.
• Reduced Risk: Batteries make up over 50% of an EV’s cost knowing their condition is crucial.

This passport will solve the biggest problem in India’s used EV market uncertainty around battery life.

Why Did Maharashtra Launch This Now?

Maharashtra is the second-largest EV market in India, with over 2.42 lakh EVs sold in 2024, just behind Uttar Pradesh. With EV sales rising across the country (a 27% jump last year), resale and battery tracking have become very important.

Globally, the European Union will make battery passports mandatory for all EV batteries over 2kWh by February 2027. Maharashtra is ahead of the curve and setting an example for other Indian states.

Used EV Market in India – What’s the Real Problem?

While ICE (internal combustion engine) cars retain around 50% of their value after 3-5 years, EVs lose 3–5% more, mainly due to uncertainty about the battery.

That’s where this battery passport becomes a powerful tool. When buyers know the battery status, they are more willing to pay the right price.

How Will This Work?

Though the Maharashtra government hasn’t yet explained all the details, here’s what we can expect:

• EV manufacturers and dealers might issue the battery passports.
• QR codes may be used to access battery details.
• Battery data could be stored in a digital system for verified and real-time access.

This will make buying and selling used EVs much more transparent and stress-free.

Expert Opinions

According to Nikhil Dhaka, a policy expert at Primus Partner, Europe has already seen positive results with similar digital battery passports. Trust levels and transparency in used EV sales improved significantly.

Sandeep Dadia, CEO of Lockton India, also added that this move will help insurers assess battery risk and offer fair premiums based on actual usage.

What This Means for EV Future in India

With Maharashtra’s digital battery passport move, EV buyers and sellers will feel more confident. It will also:

• Encourage more people to choose EVs
• Improve the used EV market
• Help insurance and service providers with real data
• Support India’s overall EV push

This small step could go a long way in building a reliable and transparent EV ecosystem.
