Megawatt Charging Systems Patents: Leaders & White Space 2026
- A thin, uneven field. Only 12 published records sit inside this search scope, with a ranked leader at 5 families and a fifth-place entrant at just 1.
- Filing is barely underway. Activity was essentially zero through 2017-2023 before a peak of 6 records in 2024, so the dataset captures an opening phase, not an established one.
- Claims cluster in one class. 91.7% of the 12 records carry a B60L classification, while cooling (H02G), grid interconnection (H02J) and protocol/data classes each sit at 16.7% or below.
What the megawatt charging system patent record actually shows
Megawatt charging systems (MCS) are the connector, cooling and control stack built to push charging power for heavy-duty trucks and buses well beyond passenger-vehicle DC fast charging. The 12 published records captured under this search combine terms for the charging system itself with claim language around connector current rating, liquid-cooled cable, grid connection capacity, communication protocol, thermal derating and depot deployment – the practical sub-problems a megawatt-class connector and cable set has to solve. Publication lags filing by roughly 18 months, so the most recent year in this dataset is understated and should be read as a floor, not a ceiling.
With only 12 records and 8 ranked assignees, this is a landscape still being drawn rather than one that has settled. The IPC composition already shows where applicants are putting claim effort – electric vehicle propulsion architecture dominates, while cable cooling, grid capacity and communication protocol each appear in a minority of records. That imbalance is itself the finding: it marks where claim space is thin enough for a well-drafted first mover to stake ground.
Filing trend and technology composition
Two views of the same 12 records: when they were filed, and which IPC subclasses their claims touch. Because a single record can carry several IPC classes, the composition shares add up to more than 100% of the record total.
Filing trend, 2017-2026
Filings were flat at zero from 2017 through the early years of the window, then rose to a peak of 6 records in 2024 – the clearest signal in this dataset that megawatt charging system claims only began accumulating in volume very recently. The 2026 figure is partial by definition of the data cut-off and should not be read as a decline.
IPC subclass composition (share of 12 records)
B60L (electric vehicle propulsion) appears in 91.7% of records, confirming that most filings anchor their claims in vehicle-side charging architecture. H02G (power and signal cable installation) reaches 33.3%, while G06Q, H02J and H04L – commerce/billing, grid systems and digital communication – each sit at 16.7%, with G01C, G06F and G07F each at a single record.
Shares are the percentage of the 12 records in scope. A patent can carry several IPC classes, so the shares add up to more than 100%.

US20250030575A1 – Megawatt charging system adapter
An adapter for an electric charging system of an electric vehicle is provided. The adapter includes an input interface configured to couple to a charger, an output interface configured to couple to a charging inlet of an energy storage device, and at least one power conductor connected to the input interface and to the output interface. The power conductor conveys current between the charger and the charging inlet. A communication conversion unit receives a first communication signal from the charger via the input interface, in a first protocol, and translates that signal.Filed by ABB E-Mobility, published 2025-01-23, cited 1 – the highest citation count recorded in this scope.

Three observations follow directly from the evidence, without extrapolating beyond it.
A leader has emerged, but the field is still open
The ranked leader holds 5 families against a fifth-place assignee at 1, inside a ranking of only 8 companies. With so few total records, that gap reflects an early mover establishing a position rather than a locked-in market structure.
Filing activity is recent and still accelerating into the data cut-off
Years before 2024 show effectively no filings in scope, and the peak of 6 records arrived immediately before the window closes. Because publication lags filing by about 18 months, real 2025-2026 filing activity is very likely understated here.
Vehicle-side architecture is claimed densely; supporting systems are not
B60L appears in 91.7% of the 12 records, while cable cooling (H02G) reaches only 33.3% and grid interconnection, protocol and billing classes sit at 16.7% or below. Claim density on the vehicle side does not mean those adjacent branches are technically solved – it means they are comparatively unclaimed.
Eureka can read the same corpus for gaps instead of for coverage: under-claimed branches adjacent to megawatt charging systems, with the prior art for and against each one.
Who holds megawatt charging system families
The ranking covers 8 companies across the 12 records in scope – not a top-50 or top-100 cut, the full set the data endpoint returns. Momentum figures show every tracked assignee at zero in the latest year, consistent with a dataset whose most recent filings have not yet fully published.
One assignee has filed more than the rest combined
The top-ranked assignee holds 5 of the 12 records in scope, well ahead of the fifth-ranked company at 1. That still leaves the majority of the ranking – six of eight companies – holding a single-digit handful of families each, a long tail rather than a settled hierarchy.
Heavy-duty vehicle makers are filing alongside charging-equipment specialists
The ranked assignees include commercial truck manufacturers as well as charging-system and adapter specialists, indicating that megawatt charging claims are being pursued from both the vehicle side and the infrastructure side rather than by one industry segment alone.
Co-filing is minimal so far
Only one co-assignee pairing appears in the dataset, between two individually named inventors. With filing volume this low, the absence of joint corporate filings is not yet a meaningful signal either way – it simply reflects how few records exist to pair.

Within this search scope – combining megawatt charging system and heavy-duty vehicle charging terms with claim language on connector rating, cooling, grid capacity, protocol, derating and depot deployment – there are 12 published records dated between 2015 and the 2026-07-31 data cut-off. That is a small, still-forming corpus rather than a mature field, and it reflects one specific search definition rather than every filing that touches high-power EV charging generally. Broader or narrower keyword scopes would return a different count.
The ranking covers 8 companies across the 12 records, with a leading assignee holding 5 families and a fifth-place company holding 1. The ranked list includes both heavy-duty truck manufacturers and charging-equipment specialists, indicating that vehicle OEMs and infrastructure suppliers are both actively filing. With so few total records, this leadership position is best read as an early mover advantage rather than a durable market lock.
B60L, the electric vehicle propulsion classification, appears in 91.7% of the 12 records, making it by far the most heavily claimed area. Cable and power installation claims (H02G) reach 33.3% of records, while grid systems, digital communication and business-process classes each sit at 16.7% or lower. That pattern suggests vehicle-side charging architecture is the most contested claim space, with cooling, grid interconnection and protocol handling comparatively open.
The filing trend shows essentially no activity in the earlier years of this window, rising to a peak of 6 records in 2024. Because patent publication typically lags the underlying filing date by around 18 months, the true filing activity for 2025 and 2026 is likely higher than currently published records show. Readers should treat the most recent one to two years in any such trend as an undercount rather than a real slowdown.
The clearest gaps sit in the sub-areas that appear in a minority of the 12 records despite being core engineering problems for megawatt-class charging: liquid-cooled cable thermal management, grid connection capacity negotiation, depot-level load balancing, cross-charger protocol translation and thermal derating control logic each show low record counts relative to the dominant B60L vehicle-architecture cluster. Low claim density in these branches does not mean the engineering problem is solved – it means the claim space is less occupied and may be more open to a well-drafted first filing.
