GM brand Chevrolet took last place in the rankings of J.D. Power 2023 U.S. Electric Vehicle Experience (EVX) Home Charging Study, which measures customer satisfaction with permanently mounted Level 2 home electric vehicle charging stations.
Major market research and consumer intelligence firm J.D. Power published the results of the EVX Home Charging Study on March 16th, 2023, ranking Tesla as delivering the highest customer satisfaction in Level 2 home charging. The study is now in its third year.
The EVX study uses a 1,000-point scale to measure the customer satisfaction index. J.D. Power and its partner PlugShare gathered survey data from December 2022 through February 2023. The survey collected responses from 13,860 respondents.
All participants in the study own an electric vehicle or a plug-in hybrid electric vehicle (PHEV) from the 2017 through 2023 model years. J.D. Power says it used eight factors, including “fairness of retail price; cord length; size of charger; ease of winding/storing cable; cost of charging; charging speed; ease of use; and reliability” to evaluate EV owner satisfaction with home charger providers.
The average score for the study was 740 out of 1,000 points. Tesla scored about 6.8 percent higher than average at 790 points, taking first place. Three other home charger providers scored above average, including GRIZZL-E, Emporia, and ClipperCreek.
Chevy’s 683 points put it at the very bottom of the customer satisfaction rankings. Wallbox, Rivian, Siemens, ChargePoint, JuiceBox, Ford, and Electrify America all fell short of the average also, but still ranked ahead of the Bow Tie among home charger customers.
Chevy ranked low in another recent electric vehicle study by J.D. Power. The J.D. Power 2023 U.S. Electric Vehicle Experience (EVX) Ownership Study ranked the Chevy Bolt EV and Chevy Bolt EUV at 716 points and 711 points respectively, well below the 730 study average.
The EVX Home Charging study investigated EV owner attitudes to Level 1 charging (household current 120-volt plug-in) and Level 2 portable chargers. However, only permanently installed Level 2 chargers qualified a provider for inclusion in the customer satisfaction ranking.
J.D. Power derived several other findings from the study. Overall satisfaction among EV owners with permanent Level 2 chargers is falling sharply. General satisfaction with the chargers dropped 12 points compared to last year’s average score of 752. In the area of cost, satisfaction plunged by 30 points.
Only 51 percent of owners are knowledgeable about utility company programs related to their home chargers, though more knowledge would likely help them save money. 49 percent of owners said they were knowledgeable about these programs last year.
The study also shows customer satisfaction with a home charger increases if the EV owner schedules charge time, lives in the “East South Central” region or certain other regions of the U.S., or if they upgraded from a Level 1 to a Level 2 permanent charger.
