Question: what is the proper way to stop charging from EVSE side? #249

This command 18.10.16 Stop Charging has to be used to set the stop charging status after it was requested by the status message Stop Charging Requested. The status message Stop Charging Requested is sent when the EV requested to stop charging.

Does it mean there is no proper way to stop the charging from EVSE side?

Hey @zhanglongqi,

gracefully stopping a charging session is only initiated by the EV per ISO15118.

May I ask you what you want to achieve?

You can try to use the charging schedules to limit the amount of energy/time used for charging.

Best regards, lho

Thanks I will try the schedule.

For this kind of application, it's better to control from the EVSE side.

I think this is what you're looking for - as per ISO15118 the EVSE can use the notification feature to let EV know it would like to stop charging, then the EV should initiate a graceful stop:

Works for me.

Hi @ColinCGC , I am also trying to stop charging from EVSE side, so I sent this command in charging loop after some condition, but it throws warning "Warning: Module did not accept command 27:75, return code: 4". Could you please give some idea where should I put this and when should it be sent to EV?

Hey @GovindMore,

the return code 4 indicates a malformed packet, please double check your packet payload.

Best regards, lho
