Patent landscape

EV Charging Hardware Supplier Landscape

A view of who is investing in EV charging hardware IP, and who files globally. For sales and BD teams selling into charger OEMs, charge-point operators, and vehicle programs: use the ranking to see where automakers, dedicated charging equipment makers, and component suppliers are concentrating R&D, and where that activity crosses borders.

Automakers hold most EV charging patent families. ABB and Siemens are the largest dedicated charging-equipment filers, and most pure-play charger companies file too few international families to rank.

Top 25 by international patent families

International family counts first, since those are what travel across markets. “Since 2018” and “Since 2023” are all families (international plus single-office) first filed on or after that year.

Methodology

Patent families first filed in 2018 or later, matched on CPC or IPC codes. “International” means filed in two or more patent offices. Source is Google Patents Public Data via BigQuery.

Codes: CPC and IPC B60L53/3x (charging station construction) and B60L53/68 (charging network operation).

Companies are merged across name variants (for example, several spelling and romanization variants of the same assignee are rolled up into one row). Universities and government research bodies are excluded, so the ranking reflects commercial filers.

Rankings reflect patent activity, not revenue. A heavy filer may be protecting a research program that has not shipped, and a low filer may still be a dominant supplier.
