BESS Digital Twin Patent Snapshot 2026
The BESS digital twin patent corpus is nascent, with 13 patent families in scope and activity concentrated heavily in India and led by Honeywell International. Filing volume surged sharply in 2025, signalling early-stage but accelerating commercial interest in real-time battery storage simulation and monitoring.
Honeywell leads a fragmented, early-stage field
Honeywell International Inc holds the top position among all ranked applicants with 2 patent records, placing it ahead of a long tail of single-record filers. The top five filers account for 35% of the combined total among the ranked applicants visible in this query, indicating modest concentration for a corpus of this size.
The tier gap between the leader and all other applicants is narrow in absolute terms — Honeywell’s 2 records versus 1 each for all remaining ranked filers — reflecting the immaturity of the field rather than entrenched dominance. No second-tier cluster has yet formed.

Honeywell’s position, backed by a focus on battery measurement and cell-level monitoring, suggests a deliberate IP build in grid-connected diagnostics. The absence of other industrial incumbents at scale leaves the assignee snapshot open to fast followers.
Note that the most recent 18–24 months of filings are subject to publication lag and likely under-represent actual activity; the 2026 figures in particular should be read as a lower bound. Longer-window growth, applicant concentration, and technology-route coverage are therefore more reliable signals than the latest-year bar alone.
Activity spiked in 2025; power-grid systems dominate the technology mix
Two lenses reveal the field’s structure: the annual filing trend shows near-zero activity before 2022 followed by a sharp 2025 spike, while the technology composition chart highlights that grid and power-supply systems account for the largest share of classified records.
Annual filing trend
Filings were zero from 2017 through 2021, then climbed incrementally in 2022 and 2023 before reaching a visible step-up in 2024 and a pronounced spike in 2025. The 2026 count of 2 records reflects publication lag and should not be read as a slowdown — actual 2026 activity is likely higher.

H02J (Power supply and grid systems) is the visible IPC class with 10 records, followed by B60L (Electric vehicle propulsion) and H01M (Batteries, cells and fuel cells) at 4 records each, and G01R (Electric and magnetic measurement) and G05B (Control and regulating systems) at 3 records each. A cluster of single-record branches — including G06N (AI models), F03D (wind turbines), and B64U (drones) — marks the outer edges of current coverage.

A system for powering 100% of an oil and gas workover rig’s operations with a battery energy storage system (“BESS”). The system consists of three major interconnected components: a BESS, a power conversion system (“PCS”), and a workover rig. The power system is specifically designed for a retrofitted electro-mechanical workover rig (with either an… (excerpt from the patent abstract)

Ranked by total forward citations. Citation counts favour older and broadly cited patent families, and broad or adjacent patents may appear when they match the search scope. Treat this section as citation context, not as a curated list of the most topic-specific patents. Some patent titles may be shown in their original, non-English language where an accurate translation could not be guaranteed.
Assignee snapshot from the current evidence set
The applicants below are visible in this query result. Because the evidence set is relatively small, read this section as a directional snapshot rather than a full competitive ranking.
Honeywell International Inc
Honeywell leads the corpus with 2 patent records and entered as a new entrant in the most recent period (trend: new entrant). Its technical focus spans G01R 31 (electric and magnetic measurement) and H01M 10 (batteries, cells and fuel cells), indicating a diagnostics-and-health-monitoring orientation consistent with its broader industrial IoT and grid software portfolio.
2 patent recordsSouthwest Research Institute
Southwest Research Institute holds 1 patent record and also entered as a new entrant in the most recent window (trend: new entrant). Its technical emphasis covers G01R 31 (measurement), G05B 15 (control systems), and H01M 10 (battery cells), suggesting a systems-integration approach that complements, rather than duplicates, Honeywell’s diagnostic focus.
1 patent recordFrequently asked questions
The current corpus contains 13 patent families in scope. This is a very small total, consistent with a nascent technology field that only began attracting filing activity from 2022 onward.
Honeywell International Inc holds the top position with 2 patent records, ahead of all other ranked applicants who each hold 1 record. Among industrial entities, Southwest Research Institute is the only other non-academic filer identified.
India accounts for 8 of the jurisdictional records in the corpus, driven by academic institutions and individual inventors. The United States follows with 4 records, and Europe (EPO) has 1.
H02J (Power supply and grid systems) is the most represented class with 10 records. B60L (Electric vehicle propulsion) and H01M (Batteries, cells and fuel cells) each appear in 4 records, and G01R (Electric and magnetic measurement) and G05B (Control and regulating systems) each appear in 3 records.
No co-applicant filings are detected in the current corpus. All identified patent records are attributed to single applicants. This is common in early-formation fields where organizations are building individual IP positions before consortium activity emerges.
The most technically motivated under-served branches are F03D (wind turbine integration with BESS digital twins, 1 record) and G06N (AI and machine-learning models for battery state estimation, 1 record). Both are sparse relative to their commercial relevance and appear to lack industrial incumbent filings.
