Question: How can I stop the charging? #271

Hi, From the EVSE side perspective, what should I do to stop the charging process with a command or condition? Could you please explain the steps required to stop charging and the functions to be used?

Hey @alabora33,

to stop the charging from EVSE side you need to send a notification to the PEV with a request to stop the charging process. The message you need is "Send notification" (18.10.20 Send Notification in the Whitebeet manual). You need to set the notification code to "StopCharging" (Renegotiation needs to be false) and the timeout to a sane timeout value. According to ISO15118-2 the PEV shall stop the charging within the timeout. If the PEV fails to stop the charging within the timeout you may stop it by turning-off control pilot or opening the mains contactors.

This also applies to #272 and #249.

Best regards, lho
