Mumbai: Tata.ev has expanded its Battery-as-a-Service (BaaS) financing programme across its entire electric vehicle portfolio, extending the option from the Tiago.ev and Punch.ev to the Nexon.ev, Curvv.ev, Sierra.ev and Harrier.ev.
The move gives buyers an alternative to purchasing an electric vehicle with the battery cost included in the upfront price. Under BaaS, the vehicle and its battery are financed separately, reducing the initial acquisition price while shifting the battery component into a separate financing arrangement.
With the expansion, all six models in Tata.ev’s current portfolio are available under the scheme.
The Tiago.ev, equipped with a 19 kWh battery in the listed configuration, has a regular starting price of ₹6.99 lakh, while its starting BaaS vehicle price is ₹4.69 lakh. Battery financing or usage cost is listed at ₹2.6 per km.
For the Punch.ev, the corresponding prices are ₹9.79 lakh and ₹6.59 lakh, respectively, with battery usage cost starting at ₹2.6 per km.
Higher up the range, the 45 kWh Nexon.ev has a regular starting price of ₹14.34 lakh and a BaaS vehicle price starting at ₹8.99 lakh. Its battery financing or usage cost is ₹4.4 per km.
Tata.ev BaaS prices and battery usage costs
| Model | Battery | Regular starting price | Starting BaaS vehicle price | Battery financing / usage cost |
|---|---|---|---|---|
| Tiago.ev | 19 kWh | ₹6.99 lakh | ₹4.69 lakh | ₹2.6/km |
| Punch.ev | 30 kWh | ₹9.79 lakh | ₹6.59 lakh | ₹2.6/km |
| Nexon.ev | 45 kWh | ₹14.34 lakh | ₹8.99 lakh | ₹4.4/km |
| Curvv.ev | 55 kWh | ₹17.19 lakh | ₹10.99 lakh | ₹5/km |
| Sierra.ev | 63 kWh | ₹18.79 lakh | ₹11.99 lakh | ₹5.5/km |
| Harrier.ev | 65 kWh | ₹21.79 lakh | ₹14.49 lakh | ₹5.9/km |
The 55 kWh Curvv.ev starts at ₹17.19 lakh under conventional pricing and ₹10.99 lakh under BaaS, with battery financing calculated at ₹5 per km.
The Sierra.ev, with a 63 kWh battery, carries starting prices of ₹18.79 lakh conventionally and ₹11.99 lakh under BaaS. Its battery financing or usage charge is ₹5.5 per km.
At the top of the listed range, the 65 kWh Harrier.ev starts at ₹21.79 lakh with the battery included, while its BaaS vehicle price begins at ₹14.49 lakh. Battery financing is listed at ₹5.9 per km.
The lower BaaS vehicle prices should not be read as straightforward discounts. Instead, they reflect the separation of the battery’s cost from the vehicle’s upfront acquisition price — in other words, the battery has not suddenly become free; the bill has simply moved to another column.
According to Tata.ev, BaaS is structured as a dual-loan financing product. The vehicle and battery are financed through separate loan accounts, with the battery EMI depending on factors including battery capacity, down payment and loan tenure.
Battery EMI does not include charging costs, maintenance, repairs or other associated expenditure. Tata.ev said it has partnered with multiple financiers to offer the programme, with financing subject to approval and applicable terms and conditions.
Commenting on the expansion, Vivek Srivatsa, Chief Commercial Officer, said:
“With the EV acceptance and demand growing many fold in the country, Customers demand choices than ever before, not just in the EVs they buy, but also in how they choose to finance them. As BaaS* becomes an increasingly visible construct in the EV market, we want to ensure that customers evaluating a Tata.ev have complete flexibility to make a fair and transparent comparison. Extending BaaS* across our portfolio gives them precisely that choice. Customers can continue to buy their EV outright, including the battery, or opt for BaaS* and lower their upfront acquisition cost. Ultimately, our endeavour is simple: give customers the freedom to choose the solution that works best for them and make the transition to electric easier.”
Tata.ev said customers choosing BaaS will receive the same vehicle technology and ownership support as buyers purchasing the vehicle and battery together, with the financing structure being the primary difference.
There are, however, important conditions attached to the advertised BaaS prices. The starting figures apply to entry variants of the respective models and assume vehicle usage of 60 km per day, except for the Tiago.ev, for which the calculation assumes 44 km per day. The figures are for personal users and exclude charging expenses.
The stated BaaS vehicle prices also exclude government and statutory charges including road tax, insurance, TCS and other government levies. Financing remains subject to the lender’s approval and terms.
By extending BaaS from its smaller electric cars to models such as the Nexon.ev, Curvv.ev, Sierra.ev and Harrier.ev, Tata.ev is making alternative battery financing a portfolio-wide proposition rather than an entry-level experiment. For buyers, that creates another way to compare EV ownership costs — though, as ever with financing, the attractive number on the showroom board is best considered alongside the full cost over the ownership period.
