Vehicle-to-Grid System for Mining Operations Patent Landscape
Vehicle-to-Grid System for Mining Operations Patent Landscape in 2026
The V2G-for-mining patent space is small but growing sharply, with 62 patent families on record and filings up 614% over the recent measurement window. Toyota-affiliated entities hold an outsized share of the corpus, making this one of the most concentrated early-growth fields in industrial electrification.
Toyota entities dominate a highly concentrated, nascent field
Toyota Motor North America Inc leads the
The top five filers — Toyota Motor North America Inc, Toyota Jidosha KK, TAE Technologies Inc, Toyota Motor Engineering & Manufacturing North America Inc, and Epiroc Rock Drills AB — account for 83% of the combined total across the hundred largest filers, signaling an unusually tight concentration for a field still in its growth phase.

Such concentration means that the foundational IP architecture — particularly in grid integration (H02J) and EV charging protocols (B60L) — is being set largely by a single corporate family, with TAE Technologies and Epiroc as the only meaningful independent challengers at this stage.
The most recent 18–24 months of filing data are likely under-counted due to standard patent publication lag and should not be read as a slowdown. Longer-window growth, applicant concentration, and technology-route coverage are therefore more reliable signals than the latest-year bar alone.
A 2022 inflection point and grid-systems dominance define the field’s trajectory
Annual filings were minimal before 2022, then surged, and the technology mix is heavily skewed toward grid-supply and EV-propulsion classes. Together these charts show a field that activated quickly and has not yet diversified broadly.
Annual filing trend
Activity was effectively zero in 2017–2018, reached a small early cluster in 2019, then jumped sharply from 2022 onward, with 2024 marking the highest single-year count to date. The 2025–2026 figures are understated by publication lag and should be read as a floor, not a ceiling.
↗ Hover for values · click a bar to ask EurekaTechnology composition
H02J (Power supply & grid systems) and B60L (Electric vehicle propulsion) are by far the dominant IPC classes, reflecting the core V2G charging and grid-dispatch logic. H02M (power conversion), H01M (batteries), G05B (control systems), and G06Q (business/admin data processing) each appear at lower levels, pointing to secondary but active sub-themes. The remaining classes — including G01R, G06N, H02S, and H04L — are sparsely represented, flagging potential adjacency gaps.

What the competitive structure means for R&D investment decisions
Four structural observations — maturity stage, applicant concentration, collaboration patterns, and geographic spread — collectively define the risk and opportunity profile for a new entrant or incumbent assessing this space.
Early Growth: annual filings still rising
The lifecycle evidence classifies this field as Growth, with annual filings still rising and the 614% recent-window growth rate confirming rapid acceleration from a near-zero baseline. The field has not yet reached a consolidation phase, meaning foundational claim positions are still contestable. Entering now means competing against a recently activated incumbent bloc rather than an entrenched, saturated one.
Growth stage83% top-5 share creates both a barrier and a gap
The top five filers hold 83% of the combined total among the hundred largest filers, an extremely high concentration for a field with only 62 patent families in scope. Toyota-affiliated entities alone drive the bulk of that share. This creates a meaningful freedom-to-operate consideration for any new entrant in grid-integration and EV-charging subclasses, while simultaneously leaving adjacent technical areas thinly covered — notably power conversion hardware, battery management, and autonomous control.
High concentrationIntra-corporate co-filing dominates; ecosystem collaboration is minimal
Observed co-applicant activity is limited to two pairs: Toyota Motor North America Inc and Toyota Jidosha KK (2 joint filings) and Y Sudha with Malla Reddy (Mr) Deemed to Be University (1 joint filing). No cross-industry or cross-institution collaboration between the industrial mining sector and energy or automotive players is yet visible in the record, which is notable given the operational complexity of mining-site V2G deployments.
Minimal ecosystem co-filingUS-centric, with selective PCT and EPO coverage
The United States leads with 37 patent records, followed by WIPO PCT at 8 and Europe (EPO) at 7. Australia and Canada each register 4 records — notable given their established large-scale mining industries. India shows 2 records. The relatively sparse PCT and EPO coverage suggests that international protection strategies are not yet mature, leaving filing gaps in key mining jurisdictions such as Chile, South Africa, and Brazil.

Toyota Motor North America leads; TAE Technologies is the primary independent challenger
Two entities stand apart from the rest of the field in both volume and technical breadth. All named players entered the record recently, consistent with the field’s Growth lifecycle stage.
Toyota Motor North America Inc
Ranked first with 34 patent records, Toyota Motor North America Inc concentrates its filings in grid-supply systems (H02J 3 and H02J 7) and EV charging protocols (B60L 53), covering both the grid-dispatch and vehicle-side charging interfaces. Its momentum is classified as a new entrant, reflecting that essentially all of its activity is recent. When combined with the 22 records held by Toyota Jidosha KK and the 7 records of Toyota Motor Engineering & Manufacturing North America Inc, the broader Toyota family has effectively structured the foundational IP landscape in this field.
patent records: 34TAE Technologies Inc
Ranked third overall with 9 patent records, TAE Technologies Inc is the leading non-Toyota applicant and the field’s primary independent challenger. Its technical focus is differentiated: it concentrates on power conversion hardware (H02M 7) and EV propulsion management (B60L 50 and B60L 58) rather than grid-supply systems, suggesting a complementary rather than directly competing patent position. Its momentum is also classified as a new entrant, indicating all filings are recent.

Under-served technical branches adjacent to the dominant V2G core
Several IPC classes appear at low share relative to the dominant H02J and B60L clusters. The two below have plausible technical relevance to mining-site V2G and realistic entry paths for new filers.
G05B · Control & Regulating Systems
With only 7 patent records and a 5% share, autonomous and adaptive control logic for V2G dispatch in mining environments is sparsely covered. Mining operations involve dynamic load profiles, remote site conditions, and mixed fleet management that standard grid-control architectures do not address. A new entrant with expertise in industrial automation or mining SCADA systems could file in this branch with limited direct overlap against the dominant Toyota corpus, which is concentrated in H02J and B60L rather than G05B.
Search this in Eureka →H02M · Power Conversion (AC/DC)
Ten patent records and a 7% share place H02M as the third-largest class but still thin relative to the core. TAE Technologies holds the most concentrated position here, but its focus is narrow. Power conversion hardware tailored to the high-voltage, high-current demands of underground or open-pit mining equipment — including bidirectional inverter designs and ruggedized DC-DC converters — remains an under-explored area. Entrants with power electronics backgrounds can target mining-specific converter topologies that differ materially from passenger-vehicle V2G converters.

Frequently asked questions
The corpus contains 62 patent families in scope. This is a small field by patent-landscape standards, consistent with its early Growth lifecycle stage and the recency of large-scale electric vehicle adoption in mining.
Toyota Motor North America Inc leads with 34 patent records, followed by Toyota Jidosha KK with 22, TAE Technologies Inc with 9, Toyota Motor Engineering & Manufacturing North America Inc with 7, and Epiroc Rock Drills AB with 4. The top five account for 83% of the combined total among the hundred largest filers.
Filing activity was near zero through 2021, then rose sharply from 2022 onward, with 2024 recording the highest annual count to date. The 614% growth figure reflects this rapid activation, likely driven by electrification mandates in mining, improvements in battery and charging infrastructure, and increasing regulatory pressure on Scope 2 emissions from mining operations.
The United States leads with 37 patent records. WIPO PCT filings stand at 8, Europe (EPO) at 7, Australia and Canada at 4 each, and India at 2. Key global mining jurisdictions such as Chile, South Africa, and Brazil are not yet visible in the evidence, suggesting geographic gaps in current filing strategies.
The most-cited document is titled ‘Methods and systems for an integrated charging system,’ with 203 citations — substantially ahead of the next most-cited work, ‘Management of battery charge to extend battery life,’ at 11 citations. Other frequently cited works cover grid adapter systems, EV charge scheduling, demand response optimization, and energy-source determination for a location.
The sparsest adjacent branches relative to the dominant H02J and B60L clusters are G05B (control and regulating systems, 7 records), G01R (electric and magnetic measurement, 2 records), and H02S (photovoltaic/solar integration, 1 record). Power conversion hardware under H02M (10 records) is also thin given its technical centrality to bidirectional V2G architectures. These branches have low incumbent density and plausible technical relevance to mining-specific V2G deployments.
