J.D. Power: Tesla chargers more reliable than competitors

The J.D. Power study found public charging satisfaction was highest among Tesla vehicle owners. On a 1,000-point scale, Tesla scored 734. The average for all other manufacturers was 558.

Tesla’s 19,500-port Supercharger network is the largest EV charging network in the U.S. Networks using the Combined Charging System — the NACS’ nonproprietary rival — have approximately 11,500 fast chargers.

“Tesla simply has the largest and most reliable fast-charging network,” the report said.

NACS charging stations will be eligible for federal subsidies under the Bipartisan Infrastructure Law and the National Electric Vehicle Infrastructure Formula Program as long as they also include a CCS connection, the White House said June 9.

Solving charging issues is a key component of the transition to electric vehicles, according to the J.D. Power report.

“Lack of public charging infrastructure has been the top consumer barrier to EV adoption for the past 12 months, followed by related issues involving range anxiety, time required to charge and inability to charge at home or work,” J.D. Power said.

“If the Tesla user experience can be replicated for the non-Tesla EV users, then adoption of NACS by non-Tesla manufacturers could improve the overall charging experience and reliability. However, it remains to be measured,” Krear said. “In the short term, opening the nation’s largest fast-charging network to non-Tesla owners helps address one of the industry’s biggest challenges, which is making more public fast chargers available.”
