Which EVs Offer Battery as a Service in India? Full List & Tiers

The single most expensive part of any electric car is the battery — often 30–40% of the price. Battery-as-a-Service (BaaS) is the industry's answer to that sticker shock: you buy the car without the battery, then rent it through a monthly fee or a per-kilometre charge. The headline price drops dramatically, but the ownership maths changes completely. Here's every EV and platform offering BaaS in India in 2026, tiered by how mature and worthwhile the deal really is — and an honest look at whether renting your battery actually pays off.
What is Battery as a Service?
Under BaaS you own the vehicle but not the battery. The battery stays the property of the manufacturer or a finance partner, and you pay to use it — typically either a fixed monthly subscription or a usage charge of a few rupees per kilometre. In return, your upfront cost falls sharply and battery-degradation risk shifts off your shoulders. The catch: you're signing up for a recurring bill for as long as you keep the car.
How we've tiered them
We've grouped India's BaaS options by how established the programme is, how transparent the pricing is, and how genuinely useful it is to a private buyer — from mainstream passenger cars down to the swap-based ecosystem that powers fleets and two-wheelers.
At a glance
| Tier | Who | Model |
|---|---|---|
| S | MG Motor | Per-km / subscription BaaS on passenger cars |
| A | Swap networks (Sun Mobility, Battery Smart) | Subscription + battery swapping |
| B | Two-wheeler platforms (Bounce, Hero Vida, Ola) | Swappable battery plans |
| Ref. | NIO (global) | Swap-station BaaS, not yet in India |
Tier S — Passenger cars with true BaaS
MG Windsor EV (and MG's wider line-up)
MG Motor is the only mainstream carmaker in India to bring Battery-as-a-Service to passenger EVs at scale. With the Windsor EV — and increasingly across MG's range — you can buy the car at a sharply reduced price and pay a per-kilometre charge of around ₹3.5/km for the battery instead. It's a genuine innovation that has pulled the entry price of a roomy electric SUV down to hatchback territory, and it's the reason BaaS is even a mainstream conversation in India.
A worked example: MG Windsor EV
Here's roughly how the two routes compare for the same car (illustrative — confirm exact figures with MG):
| With BaaS | Battery included | |
|---|---|---|
| Upfront ex-showroom price | ~₹10.00 lakh | ~₹14.00 lakh |
| Battery charge | ~₹3.5 per km | None |
| Battery cost over 1,000 km/month | ~₹3,500/month | ₹0 |
| Over 5 years (60,000 km) | ~₹2.10 lakh in fees | ₹0 extra |
If a low upfront cost is your single biggest priority, BaaS is the offering to look at first — but as the table shows, the recurring fee is real and adds up the more you drive.
Tier A — Subscription & swap networks
Sun Mobility, Battery Smart and similar
Beyond a single carmaker, a whole ecosystem of battery-swapping companies offers BaaS to fleets, e-rickshaws, and commercial EVs. You drive in with a depleted battery and swap it for a charged one in minutes, paying a subscription or energy fee. For high-utilisation commercial users — where downtime is money — this model is genuinely transformative, even if it's less relevant to the average private car buyer today.
Tier B — Two-wheeler battery plans
Bounce Infinity, Hero Vida, Ola and others
BaaS arguably makes the most sense on electric two-wheelers, where swapping a small battery is quick and cheap. Several scooter brands let you buy the vehicle without the battery and subscribe to a swap network, slashing the on-road price. It's a smart fit for daily city commuters who value zero charging downtime.
Reference point — NIO (global)
No discussion of BaaS is complete without NIO, the Chinese brand that built its entire identity around battery-swap stations and subscriptions. It's the global benchmark for how far BaaS can go — though it isn't on sale in India yet. Worth watching, because where NIO leads, others often follow.
The other side of the coin: full ownership
It's worth remembering that most carmakers in India still take the opposite approach — the battery is included in the price and backed by a long warranty (commonly eight years). Brands such as Tata, Hyundai, Mahindra and Maruti sell their EVs this way. You pay more upfront, but there's no monthly battery bill, no per-kilometre meter running in the background, and nothing to "hand back." For a lot of buyers, that simplicity is the whole point of switching to electric.
Does Battery as a Service actually save you money?
It depends entirely on how long you keep the car and how far you drive. BaaS is brilliant at one thing: getting you into an EV for less cash today. But the recurring fee adds up. Over a typical 5–7 year ownership, those monthly or per-km charges can quietly total a large share of what the battery would have cost outright — and you still don't own it at the end.
- BaaS wins if you want the lowest possible entry price, drive modest distances, or plan to switch cars every few years.
- Full ownership wins if you keep cars long-term, drive a lot, value predictable costs, and care about resale.
That last point matters more than people expect. A car you fully own — battery included — is far simpler to resell than one tied to an ongoing battery contract, and buyers pay a premium for that clarity. It's the same reason a conventionally-owned EV like the Maruti e-Vitara tends to make the long-term numbers easy: one price, a long battery warranty, no recurring meter, and the reassurance of a vast service network behind it.
BaaS lowers the price of entry, not necessarily the cost of ownership. Always do the full five-year maths — including every monthly fee — before deciding it's the cheaper option.
Verdict
Battery-as-a-Service is a genuinely clever idea that has made electric motoring accessible to thousands who'd otherwise have been priced out — and MG deserves real credit for leading it in India. If a low upfront cost is your top priority, it's well worth exploring. But read the fine print and run the numbers over the life of the car: factor in every recurring charge and the resale picture. For many buyers, the cleaner long-term value still lies in simply owning the whole car — battery and all — and treating an EV like any other dependable, fully-owned vehicle.
Frequently asked questions
Which car company offers Battery as a Service in India?
MG Motor is the main mainstream carmaker offering BaaS on passenger EVs in India, letting buyers purchase the car at a reduced price and pay a per-kilometre charge for the battery. A wider ecosystem of swap networks (such as Sun Mobility and Battery Smart) offers BaaS to fleets and two-wheelers.
Is Battery as a Service cheaper than buying the battery?
Only sometimes. BaaS lowers your upfront cost, but the recurring fees add up over years of ownership. Over a typical 5–7 year period the total can approach the battery's outright price — and you won't own it at the end. Always calculate the full lifetime cost.
Does Battery as a Service affect resale value?
It can. A car with an ongoing battery contract is more complex to resell than one you own outright, which can affect demand and price. Fully-owned EVs with included batteries and strong service backing tend to hold value more predictably.
Programmes, pricing and per-kilometre charges are indicative and change frequently — always confirm current Battery-as-a-Service terms with the respective brand before buying.
