Virtual Power Plant EV Charging Infrastructure Patent Landscape 2026
- Ten families, no runaway leader. the strongest co-assignee pair files together just once, so no single group has locked up this claim space yet.
- China accounts for five of the nine identified receiving offices. filings from the US, EPO, HK and WIPO trail well behind, marking where enforcement geography is currently thin.
- 2024 is the peak year so far at four filings, but the 2022 midpoint of three shows growth has been flat rather than accelerating into that peak.
What this landscape covers
This dataset tracks patent families at the intersection of virtual power plant (VPP) orchestration and EV charging control — filings that combine aggregated distributed energy management with bidirectional or load-managed charging, classified under B60L53/60, H02J7 and H02J3/32. It is a narrow, still-forming corner of smart grid IP: ten published families across the full 2015–2026 window, most of them recent.
Because publication lags filing by roughly 18 months, the 2025–2026 count understates real filing activity; treat the most recent year as a floor, not a ceiling. The picture that follows is therefore about structure — who is filing, where, and against which IPC classes — rather than a finished market map.
Filing trend and technology composition
Two views of the same ten families: when they were filed, and which control-systems classes they touch.
A flat, low-volume trend with one recent peak
Filings sit at zero in 2017, build unevenly through the low single digits, reach a midpoint of three in 2022, and peak so far at four in 2024. There is no compounding growth curve here — this reads as a field with sporadic entrants rather than an established filing cadence, and the most recent years are still filling in as publications catch up.
H02J dominates; B60L is present but secondary
Every one of the ten records touches H02J (power supply and grid systems), confirming this is fundamentally a grid-control dataset that happens to interface with EV charging — only five records also carry a B60L (EV propulsion) code. G06Q and G05B appear in a minority of filings, suggesting that commerce-layer aggregation logic and closed-loop control are still secondary claim elements rather than the primary invention in most filings.
Shares are the percentage of the 10 records in scope. A patent can carry several IPC classes, so the shares add up to more than 100%.

Citation counts inside this corpus favour older filings simply because they have had longer to accumulate citations — read them as a signal of influence on later filers, not as a current importance ranking. Two of the five most-cited records share the same title and assignee family, filed as separate US applications.
Patent titles are shown in the language they were filed in, not translated, so that each record stays verifiable against the original filing — a translated title will not match in Eureka or in any national register. Publication numbers are shown where the record carries one (6 of 6 rows); clicking a row searches Eureka by that number.

Reading the trend, the IPC split and the citation table together points to a field that is still being defined rather than consolidated.
A dataset this small rewards precise claims
With only ten families across the full window, no single assignee has built a defensive thicket. A well-drafted claim on a specific control method — rather than a broad VPP-plus-charging concept — has real room to stand out and to be enforced without immediately colliding with prior art.
Filing geography is lopsided, not global
Five of the identified receiving offices are Chinese, with the US, EPO, HK and WIPO each holding one or two. Anyone filing for enforcement in Europe or against EPO designations is working against a much thinner prior-art base than someone filing in China.
Grid control is the anchor class, EV propulsion is optional
Every record sits in H02J; only half also carry a B60L code. That split suggests the inventive core in most filings is the grid-facing aggregation or dispatch logic, with the EV charging interface treated as one application among others rather than the primary claim subject.
Almost no joint filing activity
Only one co-assignee pair appears in the entire dataset, and it is a single occurrence. That points to a field of independent filers rather than consortia or joint-venture R&D, which in turn means licensing and cross-filing negotiation history is thin to work with.
Eureka can read the same corpus for gaps instead of for coverage: under-claimed branches adjacent to virtual power plant ev charging infrastructure, with the prior art for and against each one.
| Assignee | Co-assignee | Shared families |
|---|---|---|
| Shenyang Northern Huamao Construction Technology Engineering Co., Ltd. | Huamao (Liaoning Shenfu New District) Construction Technology Co., Ltd. | 1 |
The one identified co-assignee pair — a construction-technology parent and its regional affiliate — filed together once. There is no visible pattern of joint ventures or supplier-OEM co-filing in this corpus yet.
Who is filing, and where the field is still open
Recent-year momentum across the named assignees is uniformly flat: every tracked entity shows zero filings in the latest year, and one shows a full -100% year-on-year drop. That is consistent with a data-lag effect as much as a real slowdown, but it also means no assignee here has yet demonstrated sustained, compounding filing activity.
No assignee is currently accelerating
Every named filer in the momentum table — from robotics and consultancy firms to a telecom operator — shows zero filings in the most recent year. Given the publication lag, this likely understates 2025-2026 activity rather than confirming a genuine pullback, but it means rankings here are not yet stable.
Ownership is fragmented, not consolidated
With ten families spread across a mix of Chinese construction-technology firms, a Finnish telecom operator, and other independent filers, no assignee has built a portfolio dense enough to dominate freedom-to-operate analysis. That fragmentation is itself the finding: this is a market position still up for the taking.
A telecom operator, not a utility, filed the PCT route
The only WIPO/PCT record in the dataset comes from ELISA OYJ, a telecom operator rather than a traditional grid or automotive player. That signals VPP-EV charging control is attracting filers from outside the expected utility and OEM set.

Where to take this analysis
The structural picture is clear; the next step is testing specific claim language against this small but active corpus.
Map claims against the H02J/B60L split
Before drafting, check whether a proposed claim reads as pure grid-control (H02J only) or genuinely bridges into EV propulsion (B60L). The dataset shows the latter is the less-crowded half.

This landscape identifies 10 patent families published between 2015 and 2026 that combine virtual power plant (VPP) or aggregated distributed energy claims with smart EV charging, V2G aggregation, or bidirectional charging elements, classified under B60L53/60, H02J7 or H02J3/32. That is a small, still-developing corpus rather than a mature filing area. Because publication typically lags filing by around 18 months, the true number of filings from 2024 onward is likely higher than currently visible.
China leads with five of the identified receiving offices, followed by the United States with two, and single filings through the EPO, Hong Kong and WIPO's PCT route. This lopsided geography means enforcement and freedom-to-operate risk is concentrated in China, while Europe and other PCT-designated markets currently carry a much thinner prior-art base. Filers targeting non-Chinese markets should treat that as an opportunity rather than an oversight in the data.
No single assignee dominates this corpus. The strongest co-assignee relationship identified — between a Chinese construction-technology firm and its regional affiliate — appears only once, and every tracked assignee shows zero filings in the most recent year. The field currently looks like a set of independent filers rather than one led by an established grid or automotive incumbent, which is unusual for a smart-grid subfield this specific.
WO2024227976A1, filed by ELISA OYJ and published 2024-11-07, is a computer-implemented method for managing a set of battery-based assets in a virtual power plant. It groups assets into a reserve group and one or more active groups, then offers assets from the active groups for grid frequency balancing on receipt of an activation signal, while holding the reserve group back. It is notable as the dataset's only WIPO/PCT filing and as a filing from a telecom operator rather than a traditional utility or OEM.
Based on the IPC composition, the clearest gaps sit in the areas that appear in only a minority of the ten families: G06Q-linked billing or tariff settlement logic layered on top of V2G aggregation, and G05B closed-loop control applied specifically to distributed charger clusters. Cross-border PCT filings on dispatch methods are also rare — only one appears in this corpus. Any of these combinations is a candidate for a first claim rather than one competing against dense prior art.
