Battery Swapping – Swapping a drained EV battery for a charged one in minutes instead of plugging in.
- 98 battery-swapping companies (a model formalised only in 2022)
- 1,569 Battery Smart stations (281,000 batteries in circulation)
- 100m swaps completed (by the market leader alone)
- <5 min to swap a 12m bus (two packs, demonstrated July 2026)
A rider pulls up to a kiosk the size of a vending machine, slides a depleted pack out, slides a charged one in, and is back on the road in under ninety seconds.
Charging takes thirty minutes on a fast charger and up to eight hours at home. For someone whose income depends on uptime, thirty idle minutes is thirty minutes of lost fares, compounding daily.
Underneath sits Battery-as-a-Service: buy the vehicle without the battery, pay a subscription for energy. India has at least 98 swapping companies; the leader runs 1,569 stations. In 2026 the format moved to twelve-metre buses.
The signal to watch: Consolidation among the 98 operators. A swap network is worth only as much as its ubiquity.
Where we would take your group
- A swap station at shift change. Ninety seconds, repeated, and the queue around it.
- A Battery-as-a-Service operator. Who owns the pack and carries the degradation risk.
- A cell assembly line. The part of the chain India still imports.
Questions for the debrief
- Battery-as-a-Service moves battery ownership, degradation risk and capital cost off the driver. Who should bear those in your students’ markets, and who currently does?
- SUN Mobility put swap stations inside Indian Oil’s retail network. What other incumbent footprints are secretly the cheapest route to a new infrastructure?
- Ninety-eight operators cannot all survive. What does consolidation do to a network whose value depends on ubiquity?
