800V HV Connector Interface Patent Snapshot 2026
The 800V high-voltage connector interface space is an emerging, nascent patent field with only 4 patent families on record and activity concentrated almost entirely in FCA US LLC. Filing began in earnest only in 2023, signalling that the domain is still in its earliest formative stage with substantial room for new entrants.
FCA US LLC holds near-total control of a nascent field
FCA US LLC ranks first with 3 patent families, representing the overwhelming majority of documented activity in this space. Anhui Xiangyu Intelligent Technology Co., Ltd. is the only other named filer, holding 1 patent family.
The top five filers collectively account for 100% of the ranked applicants visible in this query’ combined total, and the field has only two known applicants — an extreme concentration rarely seen outside a technology’s earliest months of patent activity.

| 1 | FCA US LLC | 3 | |
| 2 | Anhui Xiangyu Intelligent Technology Co., Ltd. | 1 |
FCA US LLC’s position as the founding filer, with a technology focus spanning electric vehicle propulsion safety and protective circuit arrangements, suggests the company is using early patents to frame the IP boundary of this connector standard rather than to fence off a mature product.
Because patent applications typically publish 18–24 months after filing, the 2025 data point and any 2026 activity are likely under-counted and should not be read as indicative of actual current filing pace. Longer-window growth, applicant concentration, and technology-route coverage are therefore more reliable signals than the latest-year bar alone.
Filing began in 2023; EV propulsion dominates the technology mix
The annual filing trend and technology composition together confirm a field that emerged only recently and is anchored to electric vehicle systems engineering rather than connector hardware alone.
Annual filing trend
Zero activity was recorded from 2017 through 2022. Two families appeared in 2023, followed by one each in 2024 and 2025. The 2025 and 2026 bars are subject to publication lag and likely understate actual filings; no confirmed decline should be inferred from the apparent step-down.

B60L (electric vehicle propulsion) is the visible IPC class with 4 records, reflecting a system-level framing of the connector interface within EV charging and power management. H02H (protective circuit arrangements) appears next with 2 records, underscoring a safety focus. G01R (measurement), H02J (power supply), and H02M (power conversion) each contribute 1 record, indicating that the broader power electronics stack is beginning to be drawn into scope.

FCA US LLC
FCA US LLC holds 3 patent families and entered the field as a new entrant with all recent filings concentrated in the 2023–2025 window. Its technology emphasis spans B60L 3 (EV propulsion safety, 3 records) and H02H 5 (protective circuit arrangements, 2 records), suggesting a safety-systems framing of the 800V connector interface — focused on disconnect protection and fault management rather than the connector hardware geometry alone.
families: 3Anhui Xiangyu Intelligent Technology Co., Ltd.
Anhui Xiangyu Intelligent Technology Co., Ltd. holds 1 patent family, with IPC coverage across B60L 1, B60L 3, and H02M 1 — indicating an interest in both EV propulsion control and power conversion, which positions this filer slightly differently from FCA US LLC’s safety-circuit emphasis. No momentum data beyond entry-level presence is available given the single-family baseline.
families: 1Frequently asked questions
The current corpus contains 4 patent families. This is a very small and nascent dataset, and the actual number of active filings may be higher given publication lag in the most recent periods.
FCA US LLC is the leading filer with 3 patent families, making it by far the visible IP holder in this early-stage corpus. Anhui Xiangyu Intelligent Technology Co., Ltd. is the only other identified applicant, with 1 patent family.
The trend data shows zero filings from 2017 through 2022. Activity first appeared in 2023, with 2 families filed that year, followed by 1 each in 2024 and 2025.
The United States leads with 2 patent records, followed by China and WIPO (PCT) with 1 record each. No filings have been identified in Europe, Japan, South Korea, or other major EV markets.
B60L (electric vehicle propulsion) is the visible IPC class, with 4 records. H02H (protective circuit arrangements) appears in 2 records. G01R (measurement), H02J (power supply and grid systems), and H02M (power conversion) each contribute 1 record.
The corpus of 4 patent families and only 2 known filers indicates very low prior-art density. Adjacent IPC branches such as H02J and H02M are sparsely covered relative to the engineering scope of 800V systems, suggesting potential space for new filings — though any such decision requires a full freedom-to-operate and prior-art search beyond this landscape summary.

Patent data carries inherent limitations: recent filings (typically the most recent 18–24 months) are under-counted due to standard publication lag; counts may be reported at either a patent-family or a patent-record basis and are not always directly comparable; classification, applicant-name, and citation data may contain errors, duplicates, or omissions; and the underlying search query defines and constrains the scope shown.
