Electric Trucks Hit Megawatt Charging Milestone in California
California just completed North America's first megawatt charging session for electric trucks, solving the industry's biggest roadblock. This breakthrough means big rigs can finally charge as fast as they need to keep moving.
Electric semi-trucks just cleared their biggest hurdle in California, and it's about to change freight hauling forever.
Three companies teamed up to complete North America's first Megawatt Charging System (MCS) session at a charging hub in San Bernardino. Kempower, Windrose, and EV Realty successfully charged an electric long-haul truck using technology that delivers more than 1 megawatt of power.
That's a game changer for an industry that's been stuck waiting. Electric truck makers have been ready to roll out long-range big rigs for months, but they faced a chicken-and-egg problem: no infrastructure powerful enough to charge them quickly.
Traditional fast chargers work fine for passenger cars, but semi-trucks need something much stronger. A truck that sits charging for hours loses money, and fleet operators run on tight schedules.
The San Bernardino site tackles that problem head-on. The facility features a 1,200 kilowatt power unit connected to two MCS dispensers that can deliver up to 1.2 megawatts and 1,500 amps of continuous power.
Liquid-cooled cables handle the extreme heat generated at these power levels, keeping everything stable and safe. The result is charging that's fast enough to keep electric trucks competitive with diesel.
The Ripple Effect
This successful test sends a signal across the entire transportation industry. Suncheth Bhat from EV Realty says they're building sites that can serve any heavy-duty truck using MCS technology, and they'll be ready when new vehicles hit the road later this year.
The timing matters because several major truck manufacturers are preparing to launch MCS-capable electric semi-trucks in the coming months. Without charging infrastructure, those trucks would be stranded.
Kempower has spent the past six months testing MCS deployments across Europe, working with truck makers and logistics companies to prove the technology works at scale. Now North America is catching up.
The San Bernardino hub opens in April 2026, giving fleet operators a real solution for keeping their electric trucks moving. Other charging sites are expected to follow, creating a network that makes long-haul electric trucking practical.
The trucks are ready, and now the power is too.
