The CEC document CEC-600-2014-002 reveals some locations of the planned DCFCs along I-5 and Highway 99. The US Green Vehicle Council and Cleantech Institute have proposed the build-out of a complete DCFC network along those highways (and also a cross-country route).

Deploying a network of DC fast charging (DCFC) stations along long-distance transportation corridors will enable long-distance EV travel in California. . . This network is also needed to make EVs practical for residents of the Central Valley and rural areas who require frequent long-distance travel.
