Big EV Move in India: Tata Motors is widening its Battery‑as‑a‑Service (BaaS) plan — already available on the refreshed Punch EV — to include other affordable electric cars like the Tiago EV. This is aimed at making EV ownership easier and cheaper for budget‑conscious buyers.

🔋 What Is Battery‑as‑a‑Service (BaaS)?
Battery‑as‑a‑Service (BaaS) is not just a typical service plan — it’s a clever financing tool that helps lower the upfront cost of an EV. Instead of buying the car and the battery together, you pay separately for the battery use (like paying for fuel or electricity).
Here’s how it works:
- 📉 Lower entry price: EV’s purchase price drops because the battery isn’t included in the sticker price.
- 🔋 Battery payment per km: You pay a small charge per kilometre driven using the battery.
- 🔄 Twin EMI model: The cost of the battery and the cost of the car are structured separately, similar to two different EMIs for a loan.
This helps budget buyers feel more comfortable comparing EV costs with petrol or diesel cars.

🛠️ Why Tata Is Expanding BaaS to More Models
📊 EV pricing is still a big barrier in the sub‑₹12 lakh category — which is India’s most popular car segment, accounting for about 65 % of all car sales. But EV penetration in this price bracket is very low (around ~1.5 %), while in higher price segments adoption is much stronger.
To boost EV sales in affordable cars, Tata is expanding its BaaS option to models like the Tiago EV, which is one of India’s most popular city electric cars.
💡 BaaS Reality & Market Adoption
While the idea sounds great, only a small percentage of buyers (around ~2–3 %) have chosen the BaaS option so far even on the Punch EV. But Tata believes offering this choice helps customers compare total costs easily and consider EVs without a big upfront payment.
It’s especially useful for:
✔ budget and first‑time EV buyers
✔ city commuters who drive lower km monthly
✔ buyers comparing EV costs with petrol/CNG cars

📊 BaaS vs Traditional Purchase (Example)
Here’s a simple comparison of how BaaS can make EVs more affordable upfront:
| Purchase Type | Upfront EV Price | Battery Cost Upfront |
|---|---|---|
| Standard EV Purchase | Regular price (battery included) | ✔ Included |
| With BaaS | Lower initial price (battery excluded) | Separate per km charge |
👉 Tata Motors’ strategy reduces the initial barrier by separating the expensive battery component from the car’s base price.
📣 Why This Matters for Buyers
🔹 More Affordable EV Entry: BaaS lowers the upfront price, making EVs like Tiago EV easier for families and first‑time buyers.
🔹 Price Transparency: The dual‑EMI approach helps buyers compare EV running costs with petrol cars more directly.
🔹 Boost for EV Adoption: Expanding BaaS to entry‑level EVs could accelerate EV adoption in the budget segment and help meet future fuel efficiency norms.
