The Takeaway
- Tata Motors has expanded its Battery-as-a-Service (BaaS) model beyond the Tiago.ev and Punch.ev to additional electric vehicles.
- The model separates the vehicle and battery costs through a vehicle loan and a separate battery-related payment structure.
- Tata Motors lists different battery usage charges depending on the EV model.
- The advertised running-cost calculations are based on specified daily driving assumptions.
- Battery usage charges do not cover electricity, routine maintenance or workshop expenses.
- The programme is available to personal buyers, subject to Tata Motors’ applicable terms.
Tata Motors has expanded its Battery-as-a-Service (BaaS) model across a wider range of its electric vehicle portfolio. The financing option, initially introduced on models such as the Tiago.ev and Punch.ev, is now also available on the Nexon.ev, Curvv.ev, Sierra.ev and Harrier.ev.
The model separates the cost of the vehicle from the battery-related component, allowing buyers to pay a lower advertised ex-showroom price while making additional payments linked to battery usage. The exact financing structure, tenure and applicable terms depend on the vehicle and financing arrangement.
Tata EV Prices Under the BaaS Model
| Model | BaaS Starting Price (ex-showroom) | Battery Usage Fee |
| Tiago.ev | ₹4.69 lakh | ₹2.60/km |
| Punch.ev | ₹6.59 lakh | ₹2.60/km |
| Nexon.ev | ₹8.99 lakh | ₹4.40/km |
| Curvv.ev | ₹10.99 lakh | ₹5.00/km |
| Sierra.ev | ₹11.99 lakh | ₹5.50/km |
| Harrier.ev | ₹14.49 lakh | ₹5.90/km |
The battery usage charge varies by model. Tata Motors’ advertised calculations use specific daily driving assumptions, including 60 kilometres per day for the newly added models, while the Tiago.ev calculation uses a different usage assumption.
This means the effective cost of the BaaS arrangement depends on how much the vehicle is driven. A buyer covering fewer kilometres will pay less in usage-linked charges, while higher usage will increase the total amount paid through the battery component.

What Does the Battery Charge Cover?
The battery-related payment is linked to the battery component of the vehicle, but it does not cover the electricity required to charge the EV.
Owners will therefore need to account separately for home or public charging costs. Electricity rates can vary depending on the charging location and provider.
Similarly, routine servicing, maintenance and other workshop expenses remain separate from the battery usage charge.
A Lower Entry Price, But Compare the Total Cost
The main attraction of the BaaS model is the lower advertised vehicle price. By separating the battery component from the upfront vehicle price, Tata Motors can present a lower entry point for its electric vehicles.
However, buyers should look beyond the headline ex-showroom price and calculate the total cost over their expected ownership period. The final cost can vary according to the vehicle’s financing terms, battery usage charges, annual kilometres driven, charging expenses and maintenance costs.
The structure also means buyers should carefully review the applicable financing agreements, including loan tenure, interest rates, payment obligations and conditions related to ownership or transfer of the vehicle.
The Unboxed Truth
Tata Motors’ BaaS model changes how the cost of an EV is paid rather than eliminating that cost. The lower advertised price can make an electric vehicle appear more accessible at the point of purchase, but the battery-related payments and other ownership expenses still need to be considered.
For buyers who drive regularly and have predictable charging costs, the model may offer a useful way to reduce the initial vehicle outlay. Those driving fewer kilometres should compare the complete ownership cost against Tata’s conventional purchase structure and other EV financing options before making a decision.
Best for: Personal EV buyers looking to reduce the initial vehicle purchase outlay.
Who Is This For: Buyers considering Tata’s electric vehicles who are comfortable comparing a lower upfront price with ongoing battery-related payments.

What makes Tata Motors Battery-as-a-Service different within its category?
Tata Motors’ BaaS model separates the vehicle price from the battery-related cost, allowing buyers to access a lower advertised ex-showroom price while making additional payments linked to battery usage.
The advertised calculations use specific daily-driving assumptions, including 60 kilometres per day for the newly added models. Actual costs will vary according to the vehicle, financing terms and the number of kilometres driven.
Is Tata Motors Battery-as-a-Service worth buying?
The BaaS model may appeal to buyers who want to reduce their initial vehicle outlay and are comfortable with an ongoing battery-related payment structure.
However, buyers should compare the complete ownership cost rather than focusing only on the lower ex-showroom price. Battery usage charges, charging expenses, financing costs, maintenance and annual driving distance can all affect the overall economics. Those who drive fewer kilometres should particularly compare the BaaS arrangement with Tata Motors’ conventional purchase and other EV financing options.
