What were the Cost Drivers for Workplace Charging Installations?

The average cost for installation of electric vehicle supply equipment (EVSE) at workplace locations was $2,223. The average installation cost for workplace charging EVSE was 75 % of the average cost to install publicly accessible EVSE ($2,979). Twenty-seven percent of the workplace EVSE installed were wall-mount units, while 17 % of the publicly accessible EVSE units were wall-mount units. Greater flexibility in the location of the workplace installations provided installation cost savings opportunities not typically available to EVSE installed for public use. Future expansion of workplace charging infrastructure represents a significant installation cost concern for employers, because these expansions will frequently require additional electrical service capacity
