- DC fast-charging utilization has improved, in line with Energy
- Ease of charging and cost acceptance have been the most important differentiator between Tesla’s community and others
- Some 19% of these surveyed stated they’d encountered inoperable chargers
Buyer satisfaction with public EV charging continues to enhance, with Tesla remaining on prime, in line with a brand new J.D. Energy research.
Whereas points stay, J.D. Energy discovered enhancements over the primary two quarters of 2024. Satisfaction with DC quick charging elevated to 664 factors on a 1,000-point scale, a 10-point improve from the identical interval in 2023. Satisfaction with Degree 2 AC charging noticed a slight dip of three factors, with a rating of 614.
Amongst Degree 2 customers, satisfaction improved in 5 of the ten components that comprise these rankings, although, and DC quick charging noticed satisfaction enhance in six of these 10 areas. One sticking level with AC charging was velocity, the place satisfaction with Degree 2 chargers dropped 4 factors, to 451. Satisfaction with DC fast-charging velocity elevated from 588 factors in 2023 to 622 factors in 2024.
GM and Pilot Firm’s EV charging community
Whereas one other J.D. Energy research printed in June indicated the Tesla Supercharger community was shedding its edge, it remained the highest-ranked DC fast-charging community for the fourth yr in a row. The Tesla Vacation spot community was additionally the highest-ranked Degree 2 community.
The most important gaps between Tesla and non-Tesla charging experiences have been cost and ease of charging, in line with J.D. Energy. Tesla lists prospects begin charging shortly by way of automated funds, which research knowledge confirmed is especially necessary to EV drivers, however different automakers and charging networks have been slower to implement equal automated cost techniques like Plug & Cost.
The truth that some homeowners of non-Tesla EVs can now entry the Tesla Supercharger community due to automakers’ adoption of the North American Charging Customary (NACS) could also be an element within the improve in general satisfaction with charging, J.D. Energy says. However constant reliability features will doubtless rely on assured interoperability between automobiles and charging stations as nicely.
Gravity EV charging heart in New York Metropolis
And reliability continues to be a difficulty, in line with J.D. Energy. Of EV homeowners surveyed for this research, 19% reported visiting a charging station and never with the ability to cost their automobile. That is not precisely an enchancment from a earlier J.D. Energy research from 2023, which discovered that one in 5 charging makes an attempt fails.
The principle wrongdoer was inoperable chargers, which affected 61% of failed charging makes an attempt. Lack of chargers and/or lengthy wait occasions (20%) and broken cables or connectors (10%) have been additionally components. EVgo has introduced a program of enhancements and higher diagnostics to deal with this, but it surely appears there’s a lengthy method to go.
