# Tata Extends Battery-as-a-Service Across Its Entire EV Range > Tata EV buyers can now choose Battery-as-a-Service on the Nexon EV, Curvv EV, Sierra EV and Harrier EV, separating the vehicle price from battery payments. - **Author**: Prakash - **Published**: 2026-09-29 - **Modified**: 2026-09-29 - **Category**: news - **URL**: https://bestev.in/news/tata-extends-battery-as-a-service-across-its-entire-ev-range-20260929 --- Tata Motors Passenger Vehicles has expanded its Battery-as-a-Service (BaaS) programme across its complete electric-car portfolio in India. The financing option, previously offered on the Tiago EV and Punch EV, is now also available for the Nexon EV, Curvv EV, Sierra EV and Harrier EV. The change gives customers two ways to acquire a Tata electric car: pay the conventional price with the battery included, or pay a lower upfront vehicle price and finance the battery separately. ## Indicative Tata EV prices under BaaS The announced starting vehicle prices under the BaaS structure are: - Tiago EV: INR 4.69 lakh - Punch EV: INR 6.59 lakh - Nexon EV: INR 8.99 lakh - Curvv EV: INR 10.99 lakh - Sierra EV: INR 11.99 lakh - Harrier EV: INR 14.49 lakh These figures are not the complete cost of buying and operating the vehicle. The battery payment is separate, and the final outgo depends on the applicable plan, tenure, usage conditions and financing terms. Registration, insurance, charging, maintenance and other ownership expenses may also be additional. ## How Battery-as-a-Service works BaaS separates the battery component from the vehicle's advertised acquisition price. Instead of financing both together in a standard car loan, a buyer pays for the vehicle and battery through separate arrangements. The approach can reduce the initial loan amount attached to the car itself, potentially making monthly cash flow easier for some customers. However, the battery payment must be added when comparing BaaS with a conventional purchase. A lower headline vehicle price should therefore not be read as a discount equal to the battery's full value. Buyers should ask for a written calculation showing the car EMI, battery payment, minimum-use assumptions, tenure, interest, processing fees and total payable amount. ## Why Tata is expanding BaaS now Upfront price remains one of the biggest barriers for Indian EV buyers. Expanding BaaS from small electric cars to models such as the Nexon EV, Curvv EV, Sierra EV and Harrier EV gives customers more flexibility across different price segments. It also makes EV advertisements look closer to equivalent petrol or diesel vehicle prices. The meaningful comparison, however, is the total cost over the period a buyer expects to keep the car. ## What buyers should check before choosing BaaS Before signing a BaaS agreement, buyers should confirm: - The exact battery payment and whether it is linked to kilometres driven - Minimum monthly usage or payment commitments - Contract duration and early-closure charges - Battery warranty and degradation terms - Responsibility for battery repair or replacement - Conditions when selling or transferring the vehicle - Total payable amount under BaaS versus a normal purchase - Whether the chosen lender and insurance provider treat the two structures differently Customers with predictable monthly running may find the structure easier to evaluate. Low-mileage users should pay particular attention to minimum commitments, while high-mileage users should calculate whether per-kilometre battery charges change the ownership advantage. ## BestEV view The expansion makes Tata's EV range appear substantially more accessible, but the right decision depends on the complete payment schedule--not the reduced vehicle price alone. Buyers should request side-by-side quotations for BaaS and conventional ownership and compare the total outgo over at least five years. For shoppers already considering a Tata EV, the programme adds useful financing flexibility. It does not remove the need to calculate battery cost, charging cost and resale conditions before purchase. --- - [More news articles](https://bestev.in/news/category/news) - [All articles](https://bestev.in/news)
