Tata Motors Extends BaaS Scheme Across Entire Electric Car Lineup, Prices Start at Rs 4.69 Lakh

Tata Motors has extended its Battery-as-a-Service (BaaS) scheme to its entire electric passenger vehicle lineup in India, allowing buyers to purchase vehicles at a lower upfront cost by paying separately for battery usage.

As of September 28, 2026, the scheme covers the Tiago.ev, Punch.ev, Nexon.ev, Curvv.ev, Sierra.ev and Harrier.ev. Under the BaaS model, customers pay for the vehicle separately from the battery, with battery usage charged at a per-kilometre rate. The scheme was initially introduced for select models and has now been extended to the automaker's entire electric car range.

Tata EV BaaS Prices and Battery Usage Charges: Detailed list

Under the BaaS scheme, the starting vehicle price is lower than the standard price, while customers pay a separate charge based on the distance travelled.

The following table lists the battery capacities, standard starting prices, BaaS vehicle prices and per-kilometre battery usage charges for the models covered under the scheme.

How Tata Motors' BaaS Scheme Works

Under the Battery-as-a-Service model, the vehicle and battery are financed separately. Buyers pay the vehicle's upfront price and a recurring charge for battery usage based on the distance covered. The arrangement reduces the initial vehicle purchase cost by excluding the battery price from the upfront payment. The battery usage charge is calculated on a per-kilometre basis.

The BaaS payment covers battery usage and does not include charging, maintenance or repair costs. The total amount paid by the customer will depend on the distance travelled and the applicable usage charges.

Vivek Srivatsa, Chief Commercial Officer at Tata.ev, said the expansion gives customers the option to purchase an electric vehicle with the battery included or choose the BaaS model to reduce the upfront cost.

He said, “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.”

Financing and Ownership Costs

Tata Motors has partnered with lending institutions to facilitate financing for the vehicle and battery at dealerships. Under this arrangement, buyers may have separate loan accounts for the vehicle and battery, depending on the financing terms. The total cost of ownership under BaaS depends on the distance travelled, the per-kilometre usage charge and the loan terms.

For customers covering shorter distances, the lower upfront price may reduce the initial financial burden. However, those travelling longer distances may pay more over time through recurring battery usage charges. Buyers can also opt for the conventional purchase model, in which the vehicle and battery are included in the upfront price without a separate per-kilometre battery usage fee.

Elctrik Speaks

Tata Motors' decision to extend BaaS across its electric car lineup gives buyers another way to manage the upfront cost of purchasing an EV. While the model reduces the initial payment, the per-kilometre battery usage fee adds a recurring expense that depends on driving distance.

For buyers with lower daily running, BaaS may help manage the initial cost of ownership. However, customers with higher monthly usage will need to compare the cumulative battery charges with the cost of purchasing the vehicle with the battery included. The overall cost difference will depend on usage patterns, financing terms and the duration of ownership.
