Electric vehicle (EV) travel and DC fast charging was simulated using travel information from 48 households in the Sacramento Area using gasoline capable vehicles. Ranges of 80, 100 and 120 miles were simulated to investigate the travel that could not be completed with home charging alone. DC fast charging was the only public infrastructure in the simulation in order to highlight its possible role in a future charging network. Between 8.3% and 3.4% of tours would require some public charging under different range and charging assumptions accounting for 45% and 30% of vehicle miles traveled (VMT) respectively. By limiting the number of fast charges to 2 per tour, combined with level 2 charging at home, 27% to 7% of VMT could not be completed in an EV. The day of week and time of day charging would be needed suggested that there would be congestion at fast chargers near the weekend and around 5PM. The location of fast chargers needed was near home when vehicle range was 80 miles. The location of chargers shifted to the adjacent-region corridor when vehicle range increased 100 and 120 miles.
