EV owners are increasingly frustrated with home charging, and it should worry every electric car maker

• Expensive electricity rates are making home charging a headache.

• Home charging has long been thought of as a solution to range anxiety.

• EV owners need to learn more about cost-saving options for home charging.

Eggs, gas, and now electric vehicles. Inflation is hitting electricity rates, making EV home charging a more miserable experience for some drivers at the absolute worst time.

A new J.D. Power study of EV owners who use Level 2 home-charging stations found that overall satisfaction in the home charging experiences has declined 12 points since last year.

This could pose a real problem for the EV market, as home charging has often been held up as a solution to daily range-anxiety issues. Without a robust public charging infrastructure, daily home charging is currently key to effective EV ownership, according to automotive executives, dealers, and analysts.

"Whether you're an automaker, dealer or utility company participating in the EV ecosystem, improving the EV owner experience with respect to home charging should be a common goal shared by all," Brent Gruber, executive director of the EV practice at J.D. Power, said in the study.

Gruber pointed to several programs designed to ease the cost of EV home charging, including options to schedule charging at the most affordable times of day. But the J.D. Power study found that this is little awareness for these money-saving tricks, which brings down the overall experience.
