Kempower, together with Windrose and EV Realty, has completed its first Megawatt Charging System (MCS) session in North America, marking a milestone in the deployment of ultra-fast charging for heavy-duty electric vehicles.
The test was conducted at a charging hub in San Bernardino and utilised a Kempower Mega Satellite charger under real-world operating conditions. The installation includes a 1,200 kW power unit connected to two MCS dispensers, capable of delivering up to 1.2 MW and 1,500 A of continuous output through liquid-cooled cable technology.
The site, developed by EV Realty, is expected to open in April 2026 and is designed to support next-generation electric trucks requiring high-power charging infrastructure.
“MCS is a potential game changer for fleets looking to reduce dwell times and improve the efficiency of their operations. Fleets are excited about the trucks but have questions about where they will be able to charge,” said Suncheth Bhat, Chief Commercial Officer at EV Realty. “We are building sites that can serve any heavy-duty truck, including those utilising MCS. This test confirms that we will be ready for real-world MCS charging when the trucks hit the road later this year.”
Windrose, which supplied the electric truck used in the trial, highlighted the broader implications of the MCS standard for global charging interoperability.
“MCS is similar to what USB Type-C has done to the consumer electronics industry. Based on the ISO15118-20 ethernet communication, it allows for both a much faster flow of electrons but also a much more secure exchange of information,” said Wen Han, Chief Executive Officer of Windrose. “This is the key step to universalising high-power charging globally. Windrose is particularly invested in this technology, because our product is a global one that serves Europe, North America, South America, and Asia Pacific, and we expect all of these markets to be embracing MCS over time.”
The development follows a separate MCS trial conducted by Windrose in partnership with Autel in the Netherlands last week, although the exact charging performance achieved in both tests has not been disclosed.
Windrose has been expanding its global footprint, including plans to establish a European base at the port of Antwerp in Belgium. The site, known as ‘Windrose Park Antwerp,’ is expected to support vehicle assembly, research and development, and aftersales operations for the European market.
