Rs 6.5 lakh Tata Punch EV: Battery-as-a-Service reshapes India’s EV pricing playbook

A Tata Punch EV priced at Rs 9.7 lakh can be driven home for Rs 6.5 lakh under a battery financing plan. Hyundai’s Creta Electric falls from Rs 18 lakh to Rs 11 lakh, while Maruti’s Grand Vitara EV becomes cheaper by almost Rs 8 lakh upfront.

Those headline reductions are turning Battery-as-a-Service, or BaaS, into a powerful sales tool in India’s EV market. As more carmakers roll out battery subscription and financing models, the key question for buyers is shifting from how much cheaper the car looks to how much they will actually pay over the life of the vehicle.

Current BaaS plans charge between about Rs 2.3 and Rs 5 per km, depending on the model. A driver covering 15,000 km annually under a Rs 4-per-km plan would pay about Rs 60,000 a year, or roughly Rs 3 lakh over five years, before taxes, escalation clauses or financing charges.

Tata Motors describes BaaS as ‘primarily a financing tool, not a mobility service’ that reduces the upfront acquisition cost of EVs. ‘Having said that, we are seeing and also believe that most customers prefer outright ownership of their EVs,’ a company spokesperson said.

JSW MG Motor India, which introduced BaaS with the Windsor EV in 2024, says the model has gained real traction. ‘Today, around 12-15% of our overall EV sales come through BaaS, which is available across our MG EV portfolio,’ said managing director Anurag Mehrotra.

The upfront savings are real, but so are the recurring battery payments, minimum monthly usage commitments and financing obligations that can add several lakh rupees to ownership costs over five-to-eight years, making the total cost of ownership the more important number for buyers to track.
