Vehicle-to-Grid EV Charging Patent Landscape 2026
Vehicle-to-Grid System for EV Charging Patent Landscape in 2026
The vehicle-to-grid EV charging space is in a Growth stage, with the recent three-year filing window running well above the prior period, even as annual volume has eased from its 2022 peak. Beta Air LLC leads a fragmented field where the top five filers account for roughly one-fifth of the hundred largest filers’ combined output, signalling room for new entrants.
Beta Air LLC leads a fragmented, fast-growing field
Beta Air LLC holds the top position with 17 patent families, followed by Hyundai Mobis Co Ltd at 11 and a cluster of filers — Landis+Gyr Technologies, VITO, Rivian, InductEV, Cummins, and Guangzhou Power Supply Bureau — each contributing between 6 and 7 patent families.
The top five filers account for 22% of the hundred largest filers’ combined total, which indicates a moderately fragmented competitive structure with no single dominant actor holding an outsized share. The gap between the leader (17 patent families) and the third tier (5–6 patent families) is meaningful but not prohibitive.

Beta Air LLC’s lead is notably shaped by its eVTOL aircraft charging focus — visible in its B64F branch activity — while Hyundai Mobis Co Ltd and Rivian are pure automotive entrants. This divergence suggests the ranking mixes adjacent verticals within the broader V2G theme, creating strategic ambiguity for competitors benchmarking against the leader.
The most recent 18–24 months of filings are under-represented due to standard patent publication lag; absolute counts for 2025 and 2026 should be treated as provisional. Longer-window growth, applicant concentration, and technology-route coverage are therefore more reliable signals than the latest-year bar alone.
Multi-year growth driven by power-supply and EV-propulsion filings
The annual trend chart and technology composition chart together show that the field expanded sharply from 2020 to 2022 and that the two dominant IPC branches — H02J (power supply and grid systems) and B60L (electric vehicle propulsion) — account for the overwhelming majority of activity.
Annual filing trend
Filings rose from single digits in 2017–2019 to a peak of 39 in 2022, then settled to 38 and 32 in 2023 and 2024 respectively. The 2025 and 2026 figures reflect publication lag and are not indicative of a real decline. The 127% three-year growth rate confirms that the field is still expanding on a multi-year basis, though annual volume has eased from its 2022 peak.

What the competitive structure means for R&D strategy
Four structural dimensions — maturity, concentration, collaboration, and geography — shape the investment calculus for any entrant or incumbent in vehicle-to-grid EV charging.
Growth stage, annual pace easing from 2022 peak
The field is classified as Growth: the recent three-year filing window sits 127% above the prior three-year window. However, annual volume peaked in 2022 at 39 filings and has moderated since. Engineers entering the space will find an active but not yet saturated prior-art landscape, with foundational power-supply and EV-propulsion claims already well-staked.
Lifecycle: GrowthFragmented top tier with a modest leader gap
The top five filers hold 22% of the hundred largest filers’ combined output — a fragmentation level that keeps the field accessible. Beta Air LLC’s 17-family lead is real but not entrenched: a six-to-seven family cluster sits just below, and several of those filers (Hyundai Mobis, Rivian, Cummins) have entered recently. Differentiation through technical depth in under-served branches is a viable entry strategy.
Concentration: ModerateNo co-applicant activity detected in current evidence
The collaboration dataset returns no co-applicant filing pairs for this corpus. This absence may reflect the early commercialization stage of V2G systems, where firms are protecting proprietary architectures rather than pooling IP. It also points to a potential strategic opening: joint-development agreements or consortium filings in standards-adjacent areas (e.g., grid communication protocols) are not yet present in the record.
Collaboration: SparseUS-dominant, India emerging, China and EPO secondary
The United States is the primary filing jurisdiction by a wide margin, followed by India and Europe (EPO). China and WIPO PCT filings are present but smaller. South Korea, Australia, Canada, and Germany account for only a handful of records each. For an R&D team seeking freedom to operate, the US landscape requires the most thorough clearance work; India’s growing filing count warrants monitoring as local EV-grid infrastructure scales.
Geography: US-ledGo beyond the landscape: Eureka’s TRIZ Solution agent breaks down an R&D problem and returns patented concept solutions, each with a technical approach and cited patent & literature evidence.

Beta Air LLC and Hyundai Mobis Co Ltd: contrasting routes to the top
The two highest-ranked filers represent different strategic bets — one rooted in eVTOL aircraft ground infrastructure, the other in automotive EV propulsion — illustrating how the V2G label spans adjacent verticals.
Beta Air LLC
Beta Air LLC leads with 17 patent families, with technology emphasis concentrated in H02J 7 (power supply and grid systems), B60L 53 (EV propulsion charging), and B64F 1 (ground installations for aircraft). The aircraft ground-infrastructure focus is distinctive among V2G filers and reflects its eVTOL charging architecture. Recent three-year momentum shows a ▼ –40% trend, suggesting the initial filing burst has moderated.
patent families: 17Hyundai Mobis Co Ltd
Hyundai Mobis Co Ltd holds second place with 11 patent families and is classified as a new entrant on momentum — meaning its filing activity is concentrated in the most recent window. Its technology focus spans B60L 53 and B60L 58 (EV propulsion) and H02J 7 (grid power supply), positioning it squarely in mainstream automotive V2G. The new-entrant trajectory signals accelerating commitment from one of the largest Tier-1 automotive suppliers.

Under-served branches adjacent to the V2G core
Several IPC branches appear at materially lower filing densities relative to the dominant H02J and B60L classes, representing areas where prior-art density is thin and technical overlap with V2G is plausible.
H02M · Power Conversion (AC/DC)
With 44 records, H02M is the third-most-active branch but remains sparse relative to the core H02J and B60L classes. Bidirectional AC/DC and DC/DC converter topologies are critical to V2G inverter design, and the relatively thin coverage suggests that novel converter architectures — particularly those optimized for vehicle-side efficiency or reduced harmonic distortion — have limited prior-art obstacles. Teams with power electronics expertise have a realistic entry path via converter-level claims.
Search this in Eureka →G06Q · Business & Commerce Data Processing
Only 15 records appear under G06Q, covering billing, tariff optimization, and energy-market participation logic for V2G systems. As grid operators and utilities develop dynamic pricing schemes and aggregation platforms, the software and business-method layer of V2G remains lightly claimed. Entrants with expertise in energy-market algorithms, demand-response contracting, or fleet-level charge scheduling may find this branch comparatively open, though the commercial viability of software patents varies by jurisdiction.
