The study examines the home charging experience of EV owners across all three charger segments, but only the Level 2 permanently mounted charging station segment is award eligible. Tesla ranks highest among Level 2 permanently mounted charging stations with a score of 790. GRIZZL-E (757) ranks second and Emporia (754) ranks third. The segment average is 740. The U.S. Electric Vehicle Experience (EVX) Home Charging Study, now in its third year, is driven by a collaboration with PlugShare, the leading EV driver app maker and research firm. This study sets the standard for benchmarking satisfaction with the critical attributes that affect the total or overall EV home charging experience for both battery electric vehicles (BEVs) and plug-in hybrid electric vehicles (PHEVs). Survey respondents for the study included 13,860 owners of 2017-2023 model year BEVs and PHEVs. The study was fielded from December 2022 through February 2023.

Among those choosing to schedule home charging via an app, satisfaction is highest when using the vehicle mobile app (739) rather than the charger mobile app (706).

• Geography makes a difference with charging satisfaction: Overall satisfaction with Level 2 home charging is lower in all nine regions in this year’s study than a year ago, with New England having the largest decline of 27 points. The Level 2 satisfaction gap between regions is now 96 points (+20 from a year ago), ranging from a low of 689 in the New England region to a high of 785 in the East South Central region.
• Home charging game changer: Satisfaction improves 179 points when moving up from a Level 1 portable charger (561) to a Level 2 permanently mounted charger (740). Across the eight factors in the study, owner satisfaction is higher in seven factors once the switch is made to a Level 2 permanently mounted charger, especially with charging speed (+373 points). A majority (60%) of current Level 1 users say they are likely to upgrade their home charging station to either a Level 2 permanently mounted charger or a Level 2 portable unit.
