Question 1

Is EV battery swapping cheaper than charging a fleet?

Accepted Answer

Not on energy. Depot charging on an off-peak commercial tariff is the cheapest electricity a fleet can buy, while a swap price carries the network's float batteries, land and margin. Swapping buys uptime and avoided capex — measure it against recovered billable hours.

Question 2

How long does a battery swap take compared with charging?

Accepted Answer

A swap takes minutes. NITI Aayog puts standard charging on an e-2W or e-3W at three to four hours, but the standards PM E-DRIVE funds for these segments run to 12 kW, making a DC top-up closer to half an hour.

Question 3

Do I still own the battery if I join a swap network?

Accepted Answer

No. The Ministry of Power's January 2025 guidelines define battery-as-a-service as a model where the equipment manufacturer or a third party owns and manages the swappable batteries. You buy the vehicle without a pack and pay for energy as a service.

Question 4

Are swappable batteries interoperable across networks in India?

Accepted Answer

Not yet. There is no notified national interoperability standard for swappable packs. The 2022 draft policy allowed competing ecosystems rather than mandating one format, asking only that each station serve two OEMs.
