Long Beach-based WattEV Holdings Inc. earlier this month opened its second electric truck charging depot – this one in the city of San Bernardino.

Founded four years ago, WattEV specializes in providing charging infrastructure and services for heavy duty trucks and other freight transport.

Last summer, the company opened its first electric truck charging depot next to the Pier A terminal at the Port of Long Beach. That station, which cost roughly $9 million to develop, features 13 dual-cord 360 kilowatt chargers with the ability to charge 26 trucks concurrently with 5 megawatts of power.

This second truck charging depot in San Bernardino is four acres and has 12 dual-cord 360 kilowatt chargers with the ability to charge 24 trucks at once. The typical charging time of current heavy-duty electric trucks is two to three hours.The company said in its announcement that the station will be able to expand as the number of electric heavy duty trucks grows.

The site in San Bernardino, at 1388 S E St., was chosen for its proximity to the main trucking routes out of the San Pedro Bay port complex to the rest of the nation, including Interstate 10 to Arizona and Interstate 15 to Nevada.

“San Bernardino is a crucial site in our network,” Salim Youssefzadeh, WattEV’s chief executive, said in the announcement of the April 15 opening. “It connects many of the freight corridors that originate from the ports to the Inland Empire, as well as much of the freight that travels from distribution center to distribution center in the middle mile.”

While the cost to develop this charging depot was not disclosed, its similar size to the station at the Port of Long Beach would put the cost in the neighborhood of $9 million.
