At last count, WattEV, a provider of heavy-duty EV charging and Trucking-as-a-Service (TaaS), was operating five truck charging depots in California, and had another 15 sites under development.

Now the company has offered some details about three of the charging depots in its pipeline. WattEV is embracing the new Megawatt Charging System (MCS) standard, which can reduce vehicle charging times to 30 minutes—roughly equivalent to the time required to refuel a legacy diesel truck.

The three new sites:

• Otay Mesa—Located in an international business hub adjacent to the US-Mexico border, this site, developed in cooperation with San Diego Gas & Electric, will offer 7 MCS chargers.
• Baker—Positioned along the I-15 corridor to between California and Nevada, this depot will serve long-haul routes to Las Vegas and beyond. It will operate in collaboration with Southern California Edison, and will feature 10 MCS chargers.
• Port of Long Beach—WattEV will expand its existing charging hub at the port with the addition of 12 MCS chargers. These will feature next-generation silicon carbide-based medium-voltage power rectifiers developed by WattEV’s technology arm, Charge America.

According to WattEV, its proprietary Solid-State Transformer (SST) technology eliminates the need for step-down transformers, dramatically reducing installation complexity and cost.

“The inflection point in freight electrification is arriving with the introduction of trucks capable of megawatt charging at scale,” said Salim Youssefzadeh, CEO of WattEV. “We see 2026 as the turning point, and we are building ahead of demand to ensure that all major freight corridors in California are ready.”
