This report describes the results of the installation of 12 Level 2 electric vehicle charging ports with 12 dedicated parking spaces in two campus parking lots at California Polytechnic University State University in San Luis Obispo. The goal of the project was to bring electric vehicle charging infrastructure to the university to increase the use of electric vehicles and thus reduce emissions associated with transportation by increasing workplace and destination charging. Usage data were collected from the stations over a 13-month period ending April 30, 2016, to determine equivalent emission reductions as well as various vehicle and user statistics. Specific objectives to increase workplace charging to eight users and destination charging to 150 users were set.
The installation included 12 electric vehicle charging ports (six dual-charging stations) consisting of four Chargepoint CT4025 8-foot bollard dual charging stations and two CT4023 6-foot wall-mount dual charging stations. Greenhouse gas emission reductions were based on the number of electric vehicle miles traveled. The internal combustion engine miles displaced was determined by the measurement of energy delivered by the electric vehicle charging stations and the energy use per mile of an average electric vehicle. The estimated greenhouse gas emission reductions over the data collection period were more than 30,000 kilograms of carbon dioxide equivalent emissions and it is estimated that over the 15-year life of the project, the reductions will reach 500,000 kilograms of carbon dioxide equivalent through eventual displacement of 1.6 million internal combustion engine vehicle miles.
By the end of the 13-month data collection period, the number of workplace charging users on campus has risen to 31 users, and destination charging users have reached 163 users.
