Battery Electric Construction Machines: Patents Behind the Shift Off Diesel
Concentrated at the top. Five assignees account for 85.0% of the 20 records in scope, with the leader alone holding 7 filings. Annual filings were flat near zero through 2017-2020, then rose from 1 in 2021 to a peak of 7 in 2022 and 6 in 2024, a +500% increase across that three-year span. Treat 2025 and 2026 as undercounted rather than declining, since publication lag has not yet caught up with those filing years.

Common questions on this landscape
Who holds the most patents on battery electric construction machines?
The ranked leaders are dominated by established construction-equipment manufacturers, with the top assignee holding 7 of the 20 records in this landscape and the next four leaders combining for the remainder of the 85.0% held by the top five. This is a concentrated field: only 8 companies appear in the assignee ranking at all, and the gap between first and fifth place (7 records versus 1) is wide. A newcomer should expect to compete against a small number of well-established filers rather than a fragmented crowd.
How fast is patent filing growing for electric excavators and loaders?
Filings rose from 1 in 2021 to 6 in 2024, a +500% increase over that three-year span, with a peak of 7 filings in 2022. Because patent publication typically lags filing by around 18 months, the apparent drop in 2025 and 2026 reflects incomplete data rather than a real slowdown. Anyone tracking this field should expect the 2024 figure to remain the most reliable recent read for some time.
What technology areas do these patents actually cover?
Half of the 20 records in scope carry a B60L electric vehicle propulsion classification and 40.0% carry E02F excavating and earth-moving classifications, meaning most filings sit at the junction of drivetrain electrification and machine function. Supporting systems — thermal management, power supply, motor hardware and circuit assemblies — each appear in 10-20% of records, indicating claims on these systems are being filed but at lower density than the core propulsion and excavation claims. A record can carry multiple classes, so these percentages overlap rather than sum to 100%.
Disclaimer. This analysis is based on Patsnap Eureka data drawn from a limited snapshot of global patent records and is provided for general information and reference only. Patent data carries inherent limitations — recent filings are under-counted because of publication lag, counts may be on a record or family basis, classification and applicant-name data may contain errors or duplicates, and the underlying search query defines the scope shown — so the analysis may be incomplete or inaccurate and may not reflect the full technology landscape.
Nothing here is an exhaustive prior-art, novelty, freedom-to-operate or validity search, nor does it constitute legal, financial or professional advice, and it should not be relied upon as such. Verify independently and review with qualified patent and legal professionals before acting on it.
Method: Filing trend and technology composition. Derived from a Patsnap search on Battery Electric Construction Machines covering 2015–2026, data cut-off 2026-07-31.
