EV Battery Testing Market

The global EV battery testing market size was USD 2.68 Billion in 2025 and is expected to register a revenue CAGR of 12.8% during the forecast period. Market revenue growth is supported by China's Ministry of Industry and Information Technology publishing GB 38031-2025, "Safety Requirements for Power Batteries for Electric Vehicles," on March 28, 2025, a mandatory national standard that requires battery packs to produce no fire and no explosion for at least 120 minutes after a thermal runaway event, a 24-fold increase from the previous standard's 5-minute warning requirement, and introduces 7 new single-cell tests and 17 new pack and system tests, including a bottom impact test and a post-fast-charge external short circuit test. The standard takes effect for new vehicle type approvals on July 1, 2026, and for existing approvals on July 1, 2027, giving automakers and battery manufacturers a compressed window to requalify existing designs. UL Solutions opened a new advanced battery testing laboratory in Europe in May 2025, focused on thermal runaway, misuse, and off-gassing evaluation, adding to its existing North America Advanced Battery Laboratory in Auburn Hills, Michigan. Every new battery chemistry, cell format, and pack design introduced into an EV programme must clear a defined sequence of cell, module, and pack-level safety and performance tests before it can reach production, and tightening regulatory requirements are extending both the scope and cost of that qualification sequence. These are some of the key factors driving revenue growth of the market.

Performance and cycling testing, safety and abuse testing, environmental and durability testing, and battery management system and electrical testing are the test categories that constitute the EV battery testing market, performed using equipment and services from a concentrated group of specialist testing equipment manufacturers and accredited certification bodies. For instance, in November 2025, UL Solutions expanded its battery-powered vehicle certification services to electric motorcycles and scooters under UL 2850 and to construction, agriculture, and mining vehicles under UL 2701, covering battery management system evaluation, thermal runaway risk assessment, and functional safety testing beyond its existing passenger EV certification scope. Safety and abuse testing accounts for the largest share of testing market revenue because thermal runaway, crush, penetration, and short-circuit tests require dedicated, often destructive test infrastructure and generate the compliance documentation regulators require before granting vehicle type approval.

However, EV battery testing capacity, particularly for pack-level thermal propagation and abuse testing, requires significant dedicated laboratory infrastructure, including fire suppression systems and specialised instrumentation, that takes years to build and cannot be scaled quickly in response to a single new regulatory deadline such as GB 38031-2025's July 2026 effective date. Testing protocols and equipment must also be continuously updated as battery chemistry evolves, since a cycling and abuse test profile validated for nickel manganese cobalt cells does not automatically transfer to lithium iron phosphate or emerging sodium-ion chemistries, requiring testing equipment manufacturers and laboratories to maintain parallel qualification programmes across multiple chemistries simultaneously. Testing demand is also inherently tied to new vehicle and battery programme launch cycles, meaning testing revenue can be more cyclical than recurring battery production revenue, since a given battery design typically only requires a limited number of qualification test cycles before entering volume production. These factors substantially limit EV battery testing market growth over the forecast period.

Based on test type, the global EV battery testing market is segmented into safety and abuse testing, performance and cycling testing, battery management system and electrical testing, and environmental and durability testing. The safety and abuse testing segment commands the largest revenue share because regulatory frameworks including China's GB 38031-2025, UN 38.3 for lithium battery transport, and UL 9540A for thermal runaway fire propagation all require destructive, non-repeatable abuse tests that must be performed on production-representative cells, modules, and full packs, generating substantially higher revenue per test than non-destructive performance characterisation.

The battery management system and electrical testing segment is expected to register a rapid revenue growth rate in the global EV battery testing market over the forecast period. As battery packs incorporate increasingly sophisticated software-defined battery management systems responsible for cell balancing, state-of-health estimation, and thermal management, validating that software against functional safety standards and simulated fault conditions has become as demanding as validating the physical cell and pack hardware itself, and UL Solutions' expansion of its battery-powered vehicle certification to cover battery management system evaluation across new vehicle categories in November 2025 reflects this shift toward software and electrical validation as a distinct, fast-growing testing discipline.
