ⓘ Revenue estimates based on disclosed operator and subscriber data and primary panel calibration.
The global battery as a service market size was USD 3.85 Billion in 2025 and is expected to register a revenue CAGR of 20.4% during the forecast period. Market revenue growth is supported by the maturation of battery-as-a-service from a single company's product differentiation strategy into a regulated commercial category, with India's Ministry of Power issuing guidelines in January 2025 that formally define battery-as-a-service and establish a nationwide regulatory framework for the model. NIO, which launched the original Battery as a Service subscription in August 2020 through Wuhan Weineng Battery Asset Company, a joint venture with CATL and other partners, revised its European subscription pricing in 2025, with standard-range battery subscriptions offered from EUR 169 per month, and reported completing 100 million cumulative battery swaps under the model by February 2026. In India, Battery Smart crossed 100 million cumulative battery-as-a-service swaps in December 2025 across a network of more than 1,569 active stations, while Sun Mobility secured a USD 135 million funding round in July 2025 to expand its battery-as-a-service network for two- and three-wheelers. Every subscriber who chooses to rent rather than own a battery reduces the upfront cost of EV adoption while creating recurring, predictable revenue for the operator that owns the underlying battery asset, and this shift in who bears battery depreciation and replacement risk is what continues to draw both automakers and independent operators into the model. These are some of the key factors driving revenue growth of the market.
Battery subscription, battery lease, and pay-per-swap are the commercial ownership models that constitute the battery as a service market, applied predominantly to electric vehicles and, on a smaller scale, to stationary energy storage and industrial equipment such as forklifts and ground support equipment. For instance, India's Ministry of Road Transport and Highways clarified that electric vehicles can be legally sold and registered without a pre-fitted battery, a determination that legally separates the vehicle and battery at the point of sale and is the foundational regulatory enabler beneath every battery-as-a-service business model operating in the country today. Battery subscription, the model NIO pioneered and the model most Indian two- and three-wheeler operators have since adapted into pay-per-swap variants, accounts for the largest share of global battery-as-a-service revenue because it converts a large, one-time battery purchase into a smaller, predictable monthly cost that lowers the barrier to EV adoption for both individual consumers and commercial fleet operators.
However, battery-as-a-service business models depend on the operator retaining ownership of a depreciating asset whose replacement cost and remaining useful life must be estimated years in advance, exposing operators to the same battery-grade lithium, nickel, and cobalt price volatility that affects cell manufacturers, but without the ability to pass that cost through to subscribers mid-contract in the way a pay-per-swap or metered model can. Battery-as-a-service adoption also remains heavily concentrated in markets with either a proprietary swap network, as in China, or a dense two- and three-wheeler ecosystem built around standardised battery packs, as in India, and the model has proven substantially harder to replicate in passenger vehicle markets outside China where no comparable swap infrastructure exists to make battery subscription genuinely convenient rather than merely a financing mechanism. Second-hand vehicle resale value for battery-as-a-service vehicles also remains a persistent commercial friction point, since used car buyers and dealers must separately value a vehicle and its detachable, subscribed battery rather than a single integrated asset. These factors substantially limit battery as a service market growth over the forecast period.

Battery subscription segment is expected to account for a significantly large revenue share in the global battery as a service market during the forecast period
Based on ownership model, the global battery as a service market is segmented into battery subscription, battery lease, and pay-per-swap. The battery subscription segment commands the largest revenue share because it generates the most predictable, contractually committed recurring revenue of any ownership model, exemplified by NIO's BaaS structure, in which the Weineng Battery Asset Company owns subscribed batteries and manages their lifecycle centrally across a fleet of vehicles rather than leaving battery health management to individual owners.
The pay-per-swap segment is expected to register a rapid revenue growth rate in the global battery as a service market over the forecast period. Pay-per-swap pricing, in which commercial drivers pay only for the energy actually consumed rather than a fixed monthly subscription, aligns cost directly with vehicle utilisation, which is why gig-economy and ride-hailing two- and three-wheeler drivers in India, who generate the highest daily distance and battery cycling of any customer segment in the market, have driven Battery Smart's and Sun Mobility's growth predominantly through pay-per-swap rather than fixed subscription pricing.

Business Model Asia Pacific — Largest Revenue Share, 2025
Based on regional analysis, the Battery as a Service Market market in Asia Pacific accounted for the largest revenue share in 2025. China is the dominant country, with NIO's Battery as a Service model, launched in August 2020 through the Weineng Battery Asset Company joint venture with CATL, having reached 100 million cumulative battery swaps under the subscription model by February 2026. India is the second-largest contributor, with Battery Smart crossing 100 million cumulative pay-per-swap transactions in December 2025 across more than 1,569 active stations and Sun Mobility raising USD 135 million in July 2025 to expand its battery-as-a-service network, both operating under the Ministry of Power's January 2025 guidelines formally defining the battery-as-a-service model and the Ministry of Road Transport and Highways' clarification permitting battery-less vehicle registration. Taiwan contributes through Gogoro's subscription-based battery swapping network, which reported 648,000 subscribers as of the second quarter of 2025.
Europe
The European battery as a service market is expected to register rapid revenue growth over the forecast period. NIO revised its European Battery as a Service pricing structure in 2025, offering standard-range battery subscriptions from EUR 169 per month, as the company works to replicate its Chinese subscription model in a market without a comparable swap station density. Gogoro's partnership with Castrol, targeting a pilot energy network launch in Europe during the second half of 2025, extends a subscription-based two-wheeler battery model into the region for the first time. European battery-as-a-service adoption remains constrained by the absence of dense swap infrastructure outside a small number of pilot deployments, meaning the model functions more as a battery financing option than a full subscription-and-swap service for most European users today.
North America
The North American battery as a service market is expected to register moderate revenue growth, with early adoption concentrated in stationary energy storage and industrial equipment applications, including lithium-ion battery leasing and rental programmes for forklifts and material handling equipment, rather than passenger EV battery subscription, which remains largely absent from the US and Canadian markets given the low prevalence of standardised, swappable battery vehicle platforms. Industrial equipment operators, particularly in warehousing and logistics, are increasingly evaluating leased or subscription-based lithium-ion battery packs as an alternative to outright purchase, reducing upfront capital cost for fleet electrification.
Latin America
The battery as a service market in Latin America is expected to register moderate revenue growth from a low base, with early adoption concentrated in two- and three-wheeler delivery and ride-hailing fleets in Brazil, Colombia, and Mexico. Regional operators remain smaller and less capitalised than their Indian and Chinese counterparts, and near-term growth is expected to depend on partnerships with international battery-as-a-service operators seeking to replicate the pay-per-swap model that has proven successful in India's gig-economy delivery segment.
Middle East and Africa
The battery as a service market in the Middle East and Africa is expected to register rapid revenue growth from a low base, anchored by early-stage two- and three-wheeler electrification programmes. Sun Mobility's February 2026 partnership with Tech Skoot to deploy battery-swapping-enabled electric tuk-tuks in Kenya illustrates how Indian battery-as-a-service operators are extending their proven pay-per-swap model into markets with comparable urbanisation patterns and vehicle mixes, while Gulf state markets remain a smaller near-term opportunity given lower two-wheeler penetration.

NIO
CHINA // Passenger EV Battery Subscription (BaaS) // 100M cumulative swaps under BaaS model, Feb 2026
NIO created the modern battery-as-a-service category when it launched its BaaS subscription in August 2020 through Wuhan Weineng Battery Asset Company, a joint venture with CATL and other partners established specifically to own and manage subscribed battery packs. Its competitive advantage is the tight integration between vehicle-battery separation technology, a dense Power Swap Station network, and centralised battery health management, which together let NIO offer subscription pricing, revised in Europe to EUR 169 per month for its standard-range pack in 2025, without requiring subscribers to manage battery degradation risk themselves. NIO's 100 million cumulative battery swaps under the model, reached in February 2026, represent the largest disclosed base of battery-as-a-service transactions of any operator globally.
