The examine, performed between Feb. 12 and March 7, examined charging stations in and round San Francisco. The researchers deemed a charging level was functioning if it was in a position to cost for 2 minutes, or if a station was occupied by an EV that was being actively charged.
In accordance with the researchers, 73 % of DC quick charging factors had been thought of purposeful, whereas 23 % had been deemed “not purposeful.” Nearly 5 % had been thought of to have a “station design failure” as a result of the charging cable couldn’t attain the car’s charging port.
Widespread issues included failures with the station’s cost system, a failure to start charging, error messages displayed on display screen and clean or unresponsive screens, in keeping with the researchers.
Rempel mentioned Berkeley’s findings corroborate different latest surveys that confirmed reliability to be a priority for a lot of DC quick charger customers.
A February study by Plug In America reported that greater than a 3rd of customers mentioned damaged chargers had been not less than a “reasonable concern.”
The same variety of customers mentioned the space between stations was a problem.
“Out of the field, we’d like to verify EV infrastructure works nicely so it is not one thing folks level to and say, ‘I will wait to maneuver to an EV till the system is best,’ ” Rempel mentioned. “We have to get the infrastructure proper from the beginning, and we should not be dumping some huge cash into infrastructure that results in a poor system.”
