  • Car not charging on IOG extra slots

stevek54 Your settings look fine, apart from the fact you don't need the custom charge schedule in the Schedules section for 23:30-5:30, as WW will automatically always add that when you have IOG enabled.

    admin Why then does my battery not charge at the same time as my car charges during the extra IOG slots outside of 23:30 to 05:30?

      stevek54 Yesterday you had an IOG slot at 20:30 to 21:00 and at 21:56 through to 5:30. However, at that point you still had "Hold" set, so it wasn't charging. You have since set it to charge, so it will from now on.

      Additionally, when you get these charge schedules from Octopus earlier than 23:30 in the evening, your export instruction at 22:30-23:00 disrupts those IOG adhoc charges.

        admin Okay. So my settings are such that the next time have an IOG ad hoc charge both my EV and home battery should charge and that I need to deactivate my Export Schedule. Is that correct?

          stevek54 I would recommend to disable the export at that time yes.

          I see, from other replies, it looks like you have this sorted but, just in case, I have this...

          Also, make sure you have no schedules set in the Zappi or EV.
          If your EV has trouble waking up with split schedules from octopus, check you have "plugin charge" set to on in the Zappi head unit.

            Interesting, I've not had an issue with this. Maybe it depends on how the export schedules are configured.🤔

            Are you saying the protocol is last instruction wins, rather than import being prioritised over export?

              Yep, absolutely. Though perhaps we shouldn’t let exports run if there’s an active charge ongoing.

                admin that would definitely work for me.
                Maybe it would be worth checking with other IOG users first, as I'm sure there are others with similar export schedules.

                admin I’ve deleted my evening export charges in the hope that this sorts it for me as think it has been causing a conflict when already exporting it continues to drain the battery to charge the car.
                Hoping I’ve now got all the settings right but don’t need to charge the car today, so will see tomorrow.

                MrMessy didn’t know about the ‘plug-in’ setting. Now turned on. Thank you.

                  DJF seems to be an issue with Renault (and maybe others) where the EV doesn't like stop/start charging. Certainly, this fixed it for my daughter's Zoe.

                    MrMessy we have 2 BMW EV’s one a hybrid, that has been charging ok but hadn’t finished last night. Maybe it’s because I calculated the charge required as a percentage of the iX3 and that charges faster??
                    Think I might have to set it up for the hybrid as we use that the most and then change to the iX3 as and when because if I put in an inflated figure and the dynamic slots aren’t used I assume they’re cancelled and it will charge my battery at the day rate?
                    I’m still on a steep learning curve!

                      Slots being cancelled depends on the integration, I think. Certainly with my Zappi as long as the EV is still plugged in, the slots remain, even if no charging occurs.

                      In your scenario, I think I'd still be inclined to have Octopus set up with the larger battery vehicle, otherwise it becomes a PIA when you want to charge that one.

                      For example, lets say the iX3 is 80kWh and charges at 7kW, whereas the hybrid is 30kWh but only charges at 3.5kW, if you wanted to charge the hybrid from empty you'd ask for:
                      (30 / 80) x 200% = 75% to add.
                      In practice, if the battery in the hybrid is roughly half that of the EV, I'd just ask for 100% and not worry about it.
