A Qualitative Investigation into Charging Management Strategies in Workplace Environments

If the use of workplace chargers is poorly managed, one charger may serve just one plug in electric vehicle (PEV) per day. After 40 semi-structured interviews with PEV drivers in California, we detected several approaches to managing charging at work. If workplace charging is unmanaged, the resource is often congested, resulting in underutilization of chargers. More than half reported rules from their employer or developed by employees. Employer introduced strategies included digital queuing, time limits with pricing, and valet serviced charging. Employee introduced strategies included time limits, day restrictions, and email lists. All approaches resulted in higher utilizations of chargers
