The Promise That Launched a Policy
In April 2022, NITI Aayog published a draft Battery Swapping Policy that was widely welcomed as a pragmatic answer to one of urban electric mobility's most stubborn problems: range anxiety compounded by long charging times. The framework proposed interoperability standards, a phased rollout beginning in metropolitan cities, and financial incentives structured to lower the cost of ownership for two- and three-wheeler operators.
The consultation window closed in May 2022 with significant industry participation. Over two years later, the gazette notification that would convert that draft into enforceable regulation has not arrived. What began as a fast-tracked initiative now risks becoming a case study in policy deceleration.
What the Draft Actually Said
The 2022 framework was notable for its specificity. It proposed that battery swapping be recognised as a distinct segment under the Faster Adoption and Manufacturing of Electric Vehicles (FAME scheme), with demand incentives extended to swappable battery packs rather than only to complete vehicles. It also called for the Bureau of Indian Standards to develop interoperability protocols so that a battery charged at one operator's station could be used across competing OEM platforms.
This interoperability clause was commercially significant. Without a common standard, each swapping network becomes a closed ecosystem, limiting scale and stranding capital. The draft acknowledged this tension but deferred the resolution of technical specifications to a subsequent working group — one whose outputs have not been publicly disclosed.
The Interoperability Deadlock
Industry sources consistently identify battery interoperability as the central unresolved question. OEMs have little incentive to design open battery architectures while regulatory standards remain undefined; conversely, standardisation bodies are reluctant to freeze specifications before commercial volumes establish a dominant form factor. This classic chicken-and-egg dynamic has played out across two fiscal years.
The Bureau of Indian Standards has published safety standards for lithium-ion cells and battery management systems, but a swapping-specific interoperability standard — covering connector geometry, communication protocols and state-of-charge data exchange — remains in draft stage. Comparable regulatory journeys in China and Taiwan took between 18 and 36 months from draft to enforcement, suggesting India's timeline, while frustrating, is not unprecedented. The difference is that both those markets moved with visible government urgency.
Who Is Waiting — and Who Has Moved Anyway
Despite the regulatory gap, a cluster of Indian startups has pressed ahead. Operators like Sun Mobility, Battery Smart and Yulu have built proprietary swapping networks concentrated in the two- and three-wheeler segments, particularly for last-mile delivery fleets. Their commercial models depend on subsidised battery leasing, and the absence of a formal FAME-linked incentive for swappable packs has forced them to operate with thinner margins than originally projected.
Legacy OEMs in the two-wheeler space have adopted a more cautious posture. Without a regulatory anchor, no major manufacturer has committed to a swappable architecture as a primary product line. This matters enormously: fleet aggregators and gig-economy platforms that want to transition drivers to EVs need a hardware ecosystem broad enough to support nationwide operations, not a patchwork of city-level proprietary networks.
The Fiscal Architecture Problem
A less-discussed dimension of the delay is fiscal. Under the FAME II scheme administered by the Ministry of Heavy Industries, demand incentives are linked to vehicle price, battery capacity and the presence of a battery management system. This structure was designed for fixed-battery vehicles. Swappable batteries — which are owned by the network operator, not the vehicle buyer — do not map cleanly onto this architecture, creating ambiguity about who claims the incentive and on what basis.
Until this structural question is resolved through either an amendment to FAME II or a successor scheme, the incentive signal for swapping remains weaker than for conventional EVs. The forthcoming PM E-Drive scheme, announced in Union Budget 2024-25, offers a potential legislative vehicle to address this gap — but its detailed operational guidelines are still awaited.
Pathways Forward
The regulatory path is not closed. Three near-term interventions could meaningfully accelerate the sector. First, the government could issue an interim interoperability standard covering a minimum viable connector specification, allowing OEMs to begin platform design without waiting for a comprehensive standard. Second, PM E-Drive's operational guidelines could explicitly include swappable battery packs as an eligible asset class for demand subsidies. Third, urban local bodies in Tier 1 cities could be empowered — as the 2022 draft envisaged — to mandate swapping-ready charging infrastructure in new commercial construction, creating bottom-up network density.
NITI Aayog's broader EV roadmap positions India to have 30 percent of all vehicle sales be electric by 2030. Battery swapping, if properly regulated, is one of the most cost-effective pathways to accelerating that transition specifically for the two- and three-wheeler categories that constitute the majority of India's vehicle fleet. The policy architecture exists in draft form. The political will to finalise it is the variable that remains unquantified.
Nation Builders' Assessment
Battery swapping is not a speculative technology — it is an operational reality in hundreds of Indian cities today, functioning despite regulatory ambiguity rather than because of regulatory support. The sector has demonstrated commercial viability in constrained conditions. What it has not been given is the policy certainty needed to attract the scale of capital that would make it a genuine national mobility solution.
Two years is long enough for a consultation cycle. The cost of continued inaction is measurable: fleet operators making suboptimal hardware choices, startups raising capital at a discount to account for policy risk, and a window of urban-mobility transition that will not remain open indefinitely. A final, gazette-notified battery-swapping policy is not a luxury — it is a precondition for the segment to fulfil its stated role in India's energy transition.
