WattEV has unveiled new charging depots in southern California, with a focus on heavy-duty electric truck charging. The company has opened a new depot in Fresno and expanded its existing depot in San Bernardino, adding megawatt chargers to both locations. The upgrades include the introduction of a solid-state transformer for megawatt electric truck charging, though it is unclear if this technology is being used at both the Fresno and San Bernardino sites.
