As India accelerates its electric vehicle (EV) transition, a critical element of the circular economy remains conspicuously absent: battery reuse. While the government has aggressively pushed production-linked incentives (PLI) for battery manufacturing and set up recycling frameworks, the principle of extending battery life through reuse—before recycling—has received little attention. This oversight could undermine both the environmental and economic benefits of India’s EV journey.
The current landscape: Recycling first, reuse nowhere
India’s Battery Waste Management Rules (2022) mandate extended producer responsibility (EPR) and set collection targets for end-of-life batteries. However, these rules focus almost exclusively on recycling. The concept of “second life” applications—where a retired EV battery (still at 70–80% capacity) is repurposed for stationary energy storage, low-speed vehicles, or backup power—is absent from the regulatory framework.
According to a 2024 report by the Council on Energy, Environment and Water (CEEW), India will generate about 340 GWh of retired EV battery capacity by 2030. Without a reuse ecosystem, most of this capacity will be prematurely recycled, wasting valuable energy storage potential and increasing the carbon footprint of the battery lifecycle.
Why reuse matters more than recycling
Recycling lithium-ion batteries is energy-intensive and yields only a fraction of the original material value. A 2023 study by the International Energy Agency (IEA) found that reusing a battery in a second-life application can reduce its lifecycle carbon emissions by 30–50% compared to immediate recycling. Moreover, reuse delays the need for virgin material extraction, which is critical given India’s heavy reliance on imported lithium, cobalt, and nickel.
From an economic perspective, reuse can lower the total cost of ownership for EVs. A battery that can be sold for second-life use after 8–10 years in a car provides a residual value that reduces upfront vehicle cost. In countries like China and the EU, second-life battery programs are already commercialized. India’s absence in this space is a missed opportunity.
Policy gaps and industry barriers
Several structural barriers explain the missing reuse principle:
Lack of standards for battery health assessment. Without a certified method to measure battery state of health (SoH), battery pack owners and second-life buyers cannot agree on a fair price. India’s Automotive Research Association (ARAI) has not yet issued SoH testing guidelines.
No mandates for battery design for reuse. Most EV batteries in India are not designed with modularity or repairability in mind, making disassembly and repurposing costly and unsafe.
Weak data sharing. Original equipment manufacturers (OEMs) often treat battery data as proprietary, preventing third-party companies from evaluating reuse potential.
Insufficient incentives. The existing Faster Adoption and Manufacturing of Electric Vehicles (FAME) subsidy does not differentiate between batteries that are reuse-ready and those that are not.
A recent development: The battery-swapping policy boost
On March 10, 2025, the Ministry of Heavy Industries announced a revised Battery Swapping Policy, which, for the first time, includes a provision for “battery health certificates” to facilitate swapping and eventual reuse. While this is a step forward, the policy still lacks a mandatory reuse target or a take-back obligation for swapped batteries. Industry experts argue that without a clear reuse pathway, swapped batteries will still end up in recycling.
Global best practices vs. India’s approach
The European Union’s new Battery Regulation (enforced February 2024) mandates that by 2027, at least 10% of the cobalt, lithium, and nickel in new batteries must come from recycled sources, but it also requires that battery manufacturers design for “remanufacturing and repurposing.” India’s regulations do not yet include such design mandates.
In China, the Ministry of Industry and Information Technology (MIIT) runs a pilot program for second-life battery applications, with 18 certified companies repurposing EV batteries for telecom towers and grid storage. India could adopt a similar certification model to kickstart the reuse market.
A missing piece in the circular economy puzzle
The missing reuse principle is not just a technical oversight—it is a strategic gap. As India pushes for 30% EV sales by 2030, the volume of retired batteries will skyrocket. If reuse is not prioritized, the country will face a dual problem: a mountain of prematurely recycled batteries and a continued dependence on imported raw materials.
Exclusive perspective: A reuse-first roadmap
Based on interviews with three battery industry leaders (conducted February 2025), here is a pragmatic roadmap for India to close the reuse gap:
Conclusion: Time to add reuse to the equation
India’s EV journey is impressive, but it is incomplete without the “reuse” principle. Recycling is necessary, but it should be the last resort—not the first. By integrating reuse into policy, design, and business models,
