Rapid improvements in batteries, charging technology and vehicle electronics could create a new challenge for India’s used-EV market: vehicles may become technologically dated well before they become mechanically unusable.
The pace of technological change is measurable. According to the International Energy Agency, average EV battery-pack energy density has increased by around 60 per cent over the past decade, while battery prices have fallen by roughly 75 per cent. Average battery prices declined another 8 per cent in 2025, while advances in high-voltage architectures are also accelerating charging speeds. The first 1,000-volt EV models entered the market in 2025, underlining how quickly newer vehicles can gain technological advantages over earlier generations.
For decades, depreciation in conventional vehicles has largely followed familiar variables such as age, mileage and physical wear. Electric vehicles introduce another factor — the speed at which the underlying technology is evolving.
Battery costs, range, charging speeds, electronics and software can improve significantly within a single ownership cycle. That means a three- or four-year-old EV may compete in the resale market against a newer vehicle offering better specifications and technology, potentially at a comparable price.
Technology Could Accelerate Depreciation
Ravindra Patki, Managing Partner, Vector Consulting Group, said, “The new EV sitting next to it in the showroom likely has a better battery pack, charges faster, has more features and costs less than the old one did when it launched.”
This creates a form of depreciation that differs from conventional wear. Even a well-maintained battery with acceptable State of Health cannot necessarily compensate for a vehicle whose technology has fallen behind newer alternatives.
Sravan K Appana, CEO, iGowise Mobility, said, “In some aspects, EVs are more similar to our gadgets like smartphones and laptops. Customer tastes and preferences are changing faster than the vehicle. Battery tech is also changing fast.”
That could make residual values harder to forecast because depreciation would depend not only on the condition of the individual vehicle but also on how quickly the wider market advances.
For buyers and fleet operators, detailed usage and maintenance records will therefore become increasingly important in separating genuine deterioration from technological ageing. Aaditya Mishra, Co-Founder and Chief Growth Officer, Luxorides, said, “As the installed base of EVs grows and more vehicles enter the secondary market, greater transparency around battery condition, service history and depreciation will be critical to building confidence.”
Can The Battery Be Decoupled From The Vehicle?
One possible solution is to make EV architecture more flexible. Battery leasing, swapping and modular designs could allow the most rapidly evolving component of an EV to be upgraded without replacing the entire vehicle.
Appana has argued for battery-agnostic architectures in which durable automotive components are separated from rapidly evolving battery and electronics technology. Wider adoption of Battery-as-a-Service could similarly reduce the risk of a vehicle being permanently tied to the battery generation it originally carried.
The after-sales ecosystem will also have to keep older EVs usable as technology evolves. Pankaj Goyal, Co-Founder and COO, AutoNXT, said, “OEMs can contribute by offering certified pre-owned programmes, standardised battery-health reports, transparent battery repair and replacement pathways, accessible diagnostics and continued software support.”
Commercial fleets may offer an early test of this model. Vehicles operating with leased or swappable batteries can refresh the energy-storage system independently, potentially extending the commercially useful life of the underlying vehicle.
For India’s second-hand EV market, the challenge may therefore go beyond determining whether an old battery is healthy. The larger question is whether vehicles can be designed, financed and supported in a way that allows them to remain economically relevant even as EV technology continues to move quickly.
