TATA.ev has expanded its Battery-as-a-Service (BaaS) offering to every electric car in its portfolio, giving buyers another way to reduce the upfront cost of an EV. The move brings Nexon EV, Curvv EV, Sierra EV, and Harrier EV under the same financing framework already available on Tiago EV and Punch EV. With Tata EV BaaS, customers finance the battery separately from the vehicle through a dual-loan structure, allowing them to choose between a conventional outright purchase and a lower initial acquisition price.
The company says the expanded option offers greater financing flexibility as electric vehicle demand and acceptance continue to grow rapidly across the Indian market.
What Is Tata’s EV BaaS Offering?
TATA.ev has extended its Battery-as-a-Service programme across its complete electric vehicle portfolio. Customers can either purchase an EV conventionally, including its battery, or choose BaaS, where the vehicle and battery are financed separately through two loan accounts. This reduces the initial vehicle acquisition cost while adding a separate battery financing or usage cost.
TATA.ev Extends BaaS Across All Electric Cars
TATA.ev has announced the expansion of its Battery-as-a-Service offering to the Nexon EV, Curvv EV, Sierra EV, and Harrier EV. These models join the Tiago EV and Punch EV, which were the company’s initial EVs to receive the BaaS option.
The expansion means customers across TATA EV’s entire electric car portfolio can now consider an alternative financing structure instead of paying for the complete vehicle and battery upfront.
According to the company, the move is aimed at giving EV buyers greater flexibility in how they finance their electric cars as EV acceptance and demand continue to increase in India.
How Tata EV BaaS Works
Under the BaaS model, the battery cost is separated from the vehicle’s upfront acquisition price. Instead of financing the complete EV as a single purchase, the vehicle and battery are financed independently through separate loan accounts.
This dual-loan structure can lower the initial amount required to acquire the vehicle. The battery EMI or usage cost depends on factors including battery size, down payment, and loan tenure.
The battery financing or usage cost does not include charging, maintenance, repairs, or other associated ownership expenses.
TATA.ev has also partnered with multiple financiers for the BaaS programme, giving customers more choice when accessing the financing option.

Key BaaS Highlights
- Battery cost is separated from the upfront vehicle price.
- Vehicle and battery are financed through separate loan accounts.
- Flexible loan tenures are available, subject to financier approval.
- Battery EMI varies according to battery size, down payment, and tenure.
- Charging costs are not included in the battery financing or usage cost.
- Maintenance and repair costs are also excluded.
- Multiple financiers are available through TATA.ev.
- Customers can still purchase the EV outright, including the battery.
- The BaaS option is available to personal users under the stated conditions.
Tata EV Prices With and Without BaaS
TATA.ev’s portfolio pricing shows how the BaaS structure can reduce the starting vehicle price. The following figures apply to the entry trims of the respective models and are based on the company’s stated assumptions.
| Model | Battery | Starting Regular 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 BaaS vehicle price is therefore substantially lower than the corresponding regular starting price because the battery cost is separated from the initial vehicle acquisition price.
What Do the BaaS Prices Include?
The quoted BaaS prices apply to the entry trims of the respective models and are based on specified daily usage assumptions. For most models, the calculation assumes vehicle usage of 60 km per day, while the Tiago EV calculation assumes 44 km per day.
The stated prices apply to personal users and exclude government statutory charges. Buyers will still need to account for expenses such as road tax, insurance, TCS, and other applicable government levies.
The BaaS product is also a dual-loan finance product and remains subject to the terms and conditions and approval requirements of the participating financiers.
Customers Keep the Same EV Experience
The BaaS arrangement does not change the core product experience offered by TATA.ev. Customers opting for the financing model continue to receive the same vehicle, technology, and ownership support.
The primary difference is how the vehicle and battery are financed.
This gives buyers two broad routes: purchase the EV outright with the battery included, or select BaaS to separate battery financing from the initial vehicle acquisition.
TATA.ev’s Statement on the BaaS Expansion
Vivek Srivatsa, Chief Commercial Officer, TATA.ev, said customers are increasingly looking for flexibility not only in the EVs they purchase but also in how they finance them.
He said the wider availability of BaaS is intended to help customers make comparisons between conventional EV ownership and the separate battery-financing model while giving them the freedom to choose the option that suits their requirements.
The company also said making BaaS available across its portfolio is intended to make the transition to electric mobility easier by offering another financing route.
Why the BaaS Expansion Matters for EV Buyers
The expansion comes as the Indian electric passenger vehicle market continues to evolve beyond questions of vehicle range and charging infrastructure. Financing and upfront acquisition costs are also important considerations for consumers evaluating an EV.
By separating the battery cost from the vehicle price, BaaS changes the way the initial purchase price is presented. A customer sees a lower starting vehicle price but takes on a separate battery financing or usage cost.
For buyers comparing EVs, the relevant calculation therefore goes beyond the advertised BaaS vehicle price. The total financing structure, battery usage cost, daily driving distance, tenure, down payment, charging expenditure, insurance, maintenance, and other ownership costs should all be considered.
TATA.ev’s Complete BaaS Portfolio
With the latest expansion, the BaaS programme covers:
- Tiago EV – 19 kWh battery
- Punch EV – 30 kWh battery
- Nexon EV – 45 kWh battery
- Curvv EV – 55 kWh battery
- Sierra EV – 63 kWh battery
- Harrier EV – 65 kWh battery
The expansion makes the financing option available across TATA.ev’s range, from its smaller electric hatchback to its larger electric SUV offerings.
What This Means for Tata EV Buyers
Tata EV BaaS gives customers an additional way to structure the purchase of an electric car. Instead of treating the battery as part of the entire upfront vehicle cost, buyers can finance the vehicle and battery separately.
For customers primarily concerned with lowering the initial acquisition amount, the model may provide an alternative route to entering EV ownership. However, the lower starting vehicle price does not represent the complete ownership cost, since the battery financing or usage charge and other running expenses remain applicable.
Ultimately, customers can continue to choose a conventional purchase with the battery included or opt for the BaaS model, depending on their financing requirements, usage pattern, and eligibility.

Bottom Line
TATA.ev’s latest BaaS expansion brings its battery-financing option to the Nexon EV, Curvv EV, Sierra EV, and Harrier EV, alongside the Tiago EV and Punch EV. The model separates battery financing from the vehicle purchase, reducing the initial vehicle acquisition price while introducing a separate battery financing or usage cost.
For prospective buyers, the key consideration will be the complete cost structure rather than the lower starting BaaS price alone. Loan tenure, down payment, battery usage cost, daily driving distance, charging, insurance, maintenance, and applicable statutory charges can all influence the overall economics of the purchase.
