The number is even higher for hybrid owners. Another way to look at this though is that the majority sticks with their EV meaning greater adoption is only inevitable.
Still, that is a nice chunk that switches back. The reasons vary but having access to fast charging is still a big factor:
According to the research, about half of the respondents who bought another EV had access to Level 2 charging, compared to the 30% who dumped the electric lifestyle, but had a proper plug at home. The research found owners were 53% less likely to buy another EV if they did not have access to convenient, at-home charging. Essentially, it was a coin toss over whether an EV owner either stuck with it or returned to gas pumps.
