Wireless BMS / Cloud Battery Patent Snapshot 2026
The Wireless BMS / Cloud Battery patent corpus is nascent — 12 patent families in scope — and dominated by Indian academic and engineering institutions, with no single assignee holding more than one family. Filing activity accelerated sharply in 2025, consistent with an early-growth field where publication lag is still suppressing the most recent counts.
Academic institutions lead a fragmented, early-stage field
SRI SAL RAM INSTITUTE OF TECHNOLOGY leads the ranking with one patent family, tied with thirteen other applicants — every filer in the top 100 holds exactly one family, reflecting extreme fragmentation. No corporate incumbent has yet established a commanding position.
The top five filers account for 36% of the combined total across the ranked applicants visible in this query, which for a field this small means concentration is structurally modest: no applicant has accumulated a blocking portfolio. The tier gap between leader and follower is zero by family count.

The dominance of Indian engineering colleges and universities signals that Wireless BMS / Cloud Battery is still in an exploratory research phase rather than a commercial-deployment phase; corporate assignees such as Daymak remain isolated exceptions. This leaves the field open to first-mover advantage for industrial entrants willing to file defensively.
Filings from 2025 onward are subject to publication lag and will be revised upward as more applications publish; the 2026 figure in particular should be treated as a lower bound. Longer-window growth, applicant concentration, and technology-route coverage are therefore more reliable signals than the latest-year bar alone.
A 2025 filing surge and a power-centric technology mix
The annual trend and IPC composition charts together tell a consistent story: the field was dormant before 2021, picked up isolated filings through 2024, and then registered a sharp volume increase in 2025. Technology breadth is notable given the small corpus, but power supply and wireless networking classes anchor the mix.
Annual filing trend
Activity was zero from 2017 through 2020, reached single-digit annual counts in 2021–2022 and 2024, then jumped in 2025. The 2025 and 2026 bars are subject to publication lag and likely undercount true activity; the trend should be read as accelerating, not plateauing.

H02J (Power supply and grid systems) and H04W (Wireless communication networks) are the two visible IPC branches, consistent with the core BMS-plus-connectivity proposition. G06F (digital data processing) appears at lower frequency, reflecting emerging cloud analytics angles. Numerous low-count branches — including A61B, G02B, and footwear/headwear classes — suggest that some filings bundle BMS concepts into broader IoT or wearable applications rather than treating battery management as the primary subject.

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.
Sri Sal Ram Institute of Technology
Holds 1 patent family with technology emphasis spanning water and wastewater treatment (C02F), material analysis (G01N), and power supply systems (H02J 7). This cross-disciplinary spread is typical of an academic institution exploring BMS integration in broader energy and environmental contexts. Momentum data is not available for this applicant in the recent-period comparison.
families: 1Daymak
The sole identified corporate applicant in the ranked set, holding 1 patent family. As a manufacturer of electric vehicles and personal mobility devices, Daymak’s presence signals that commercial operators are beginning to file in this space. No recent-period momentum figure is available for Daymak, but its industry background distinguishes it from the academic majority.
families: 1Frequently asked questions
The evidence covers 12 patent families in scope. This is a small corpus consistent with an early-growth field where commercial filing activity has not yet scaled up.
Sri Sal Ram Institute of Technology leads the ranking, but with only 1 patent family — the same count held by every other ranked applicant. There is no meaningful lead by portfolio size.
India is the leading jurisdiction, with 11 patent records filed domestically. WIPO PCT filings account for 2 records. Major markets such as the US, EU, China, and Japan are not represented in the current evidence, suggesting the international landscape is largely open.
The evidence classifies Wireless BMS / Cloud Battery as a Growth-stage field, with annual filings still rising. Recent years are understated by publication lag, so the true pace of activity is likely higher than raw counts suggest.
No co-applicant or collaboration relationships are detected in the current evidence. All filings appear to be single-assignee applications, and no university–industry or consortium co-filing patterns have emerged.
H02J (Power supply and grid systems) and H04W (Wireless communication networks) are the two most frequently occurring IPC branches, reflecting the core power-management-plus-connectivity proposition of the field. G06F (electric digital data processing) appears at lower frequency, pointing to nascent cloud analytics activity.
