The California Department of Transportation (Caltrans) has added more fast-charging options along the state highways in Central California. The 22 new electric vehicle (EV) chargers span over nine locations in six counties. The Level 3 direct current (DC) fast chargers provide approximately 80 percent charge in 30 minutes to all EVs on the market with universal connectors, and enable free fast-charging capabilities with no time limit. They typically require 480V three-phase electrical power at the installation site, can restore up to 90 miles of range to an electric vehicle's plug-in battery in roughly 30 minutes, and can produce between 50 to 120 kilowatts per hour depending on the model.

The project is supporting the private sector's goal to fill gaps in the zero-emission vehicle market. In September 2020, California’s cumulative zero-emission vehicle (ZEV) sales were 763,816, including nearly 59 percent battery-electric vehicles (BEVs), nearly 40 percent plug-in hybrid vehicles (PHEVs), and over one percent hydrogen fuel cell electric vehicles (FCEVs). California Governor Gavin Newsom's goal is to have 100 percent ZEV sales by 2035. More chargers throughout the State and alongside highways, combined with decreasing vehicle costs and increasing consumer acceptance, will help incentivize the purchase of EVs.

The project also supports the Biden-Harris administration's executive order mandating the Federal Government buy ZEVs for its fleets. The executive order includes installing over 500,000 new EV charging stations across the country. The recent Transit Vehicle Innovation Deployment Center Advisory Panel Overview and Conclusions January 2021 report provides suggestions for expanding the adoption of zero-emission buses in the U.S. transit industry.

The $4.5 million projects is funded by Caltrans and the San Joaquin Valley Air Pollution Control District in Fresno, California. The primary contractor is Cal Valley Construction of Fresno. The Broadband TelCom Power, Inc. of Santa Ana, California, provided and installed the DC EV Fast Chargers. The project also used subcontractors Civil Substations, Inc., Pacific Gas, and Electric, and Southern California Edison.

Caltrans is researching a potential gas tax replacement as gas tax and other fuel tax revenues will no longer fund the infrastructure California needs as cars become more fuel-efficient. The potential gas tax replacement proposes a road charge where drivers pay to maintain the roads based on how much they drive instead of how much gas they purchase. Under this "user pays" system, all drivers share roadway maintenance and repair costs based on their use.

  • Collaborated with the private sector to fill gaps in the zero emission vehicle (ZEV) market. More chargers throughout the state will help to incentivize the purchase of EVs, getting us closer to Governor Newsom’s goal of 100 percent ZEV sales by 2035
  • Addressed regional needs for electric vehicle (EV) charging infrastructure throughout California while supporting state goals to improve air quality, combat climate change, and reduce petroleum use.
  • Reduced recharging concerns for plug-in EV drivers on long-distance trips through the Central Valley with four new EV fast chargers at the Tejon Pass Rest Area on Interstate 5, and 18 others staggered approximately 40 miles apart.
