What you need to know:
- Windrose Technology and Terawatt Infrastructure have deepened their collaboration in battery-electric semi truck and charging infrastructure development.
- During recent interoperability tests at Terawatt's flagship site in Rancho Dominguez, Calif., Windrose’s R700 Class 8 semi was charged for a 240-mile range in about 40 minutes using dual 350 kW chargers (totaling 650+ kW).
- The companies are expanding their work beyond charging hardware to include software integration, connecting vehicle systems with Terawatt’s site and energy management platforms.
- The collaboration aims to create scalable, efficient, and customer-centric charging solutions for commercial electric fleets.
Two of the biggest players in the battery-electric semi truck and charging infrastructure space have not only strengthened their existing partnership but have also achieved an impressive charging time and range test.
Windrose Technology and Terawatt Infrastructure have jointly announced a series of advanced interoperability tests at the latter's flagship site in Rancho Dominguez, Calif.
What was achieved, exactly? Windrose's dual gun charging capability, which produces over 650 kW by utilizing a pair of 350 kW chargers provided by Delta Electronics, made it possible to achieve a 240-mile range charge in about 40 minutes. The demonstration vehicle was, of course, a Windrose R700 Class 8 semi.

Windrose/Terawatt
The two companies are also cooperating beyond hardware, specifically to develop increased software integration by "connecting Windrose's vehicle systems with Terawatt's site and energy management platforms," according to the companies' joint statement.
"This partnership is about more than performance metrics — it's about delivering real-world solutions to the fleets driving the energy transition," said Wen Han, founder, chairman and CEO of Windrose Technology. "Together with Terawatt, we're aligning vehicle and infrastructure platforms in a way that scales efficiently and delivers immediate value to customers."

The companies continue to collaborate on several other programs, such as local customer deployments at Terawatt's Southern California charging hubs and longer deployments at future sites along the crucial I-10 corridor between Los Angeles and El Paso, Texas.

"By combining [Windrose's] next-generation trucks with our infrastructure, and sites designed for quick charging with the least disruption to operations, including pull-through stalls that accommodate trailers, we are unlocking new electric lanes in southern California and beyond. The deeper our collaboration goes — from power to software to site design — the better we serve our customers."
Windrose and Terawatt confirm additional joint testing will continue this summer and deployments are due to get underway by the end of this year.
The U.S. market Windrose R700 is due to begin production this July in Huntington Beach, Calif.
