Dragonfly Energy secures patent for high-powered charging technology

Dragonfly Energy has been awarded a U.S. patent for its Wakespeed Charge Control technology, which enables high-power charging between towing vehicles and trailers.

Traditionally, vehicle-to-trailer charging has been limited to just a few hundred watts through 12V connectors, which often doesn't cut it with today’s larger lithium battery systems. The newly patented Wakespeed technology increases this capability to kilowatt levels at higher voltages (such as 48V and beyond), while adding safeguards that prevent electrical arcs, protect components, and keep operation reliable during connection, disconnection, or unexpected interruptions.

“We believe this patent reinforces our competitive position by protecting technology that enables safe, efficient integration of batteries, alternators, and charging systems,” said Dr. Denis Phares, chief executive officer of Dragonfly Energy. “It highlights how we are expanding from batteries into full power system solutions across multiple industries.” 

According to the company, this provides fleets a pathway to integrate higher-power charging between tractors and trailers, supporting the shift to advanced power systems. The technology also allows OEMs to integrate high-power charging directly into their platforms.

Dragonfly Energy’s intellectual property portfolio now includes about 100 patents filed, pending, or granted.
