Target SOC Reached Before Slot/Block Ends

nbullus

I noticed that I had a charge triggered by a slot and it reached the target SOC within a few minutes but carried on importing from the grid for the full 30 min slot duration. I suspect the same happens with a block of adjacent slots and you could end up pulling from the grid for any length of time until the block ends?

Could we have the option of stopping the charge early once the target SOC is reached rather than waiting for the scheduled end time. This would be similar operation of the export where we have reached target SOC before the end time and it continues to pull from the grid for the full duration of the export schedule.

nbullus Hmm. But I guess it would only apply if hold charge is not enabled?

admin Yes

That seems to be a Giv Energy thing. If you set a Timed Charge Period and the battery reaches target SOC during this period, GE will continue importing from the grid until the end of the set period. Happens with GE portal, App and WW.

johalareewi Your right It is a GE thing, but it shouldn't have to be this way. Once SOC target is reached (export or import), it should stop and revert back to normal operation. More of a problem on export as it can cost you money depending on how long the schedule window is left after it reaches SOC target.

It could be because the value in AC Charge 1 Upper % Limit is trumping AC Charge Upper % Limit.

See my post Set the target state of charge (SOC) for the battery - New WW Agile SOC% limit

What I am finding (on Agile) is that even if SOC is reached during a charge slot, it is a cheap slot so doing grid import for the rest of the slot (or block of slots) isn't that bad. And it keeps the battery full to be used later on during the more expensive slots.

nbullus Yeah - agreed on the export one, we're working on a solution for this for Giv users.

johalareewi I agree in most cases, although I have noticed a few occasions where the next Agile slot can be cheaper than the current slot and so I use more power at the dearer slot and the cheaper slot never actually fires as the battery is already at the target SOC. Luck of the draw really. Shouldn't be an issue for Flux customers.

nbullus Then you get the situation where the overnight window has selected lots of cheap slots but it is going to be one of those Agile days where the mid morning slots are cheaper than the overnight ones.
I just remind myself I am not on the standard tariff which is the big win for me.
Shaving a few extra pence here and there is just icing.

johalareewi Agreed mate. You cant get it 100% unless you are going to continually monitor it manually, which I won't be Overall it will average itself out over the peaks and troughs and still give you the best rate over the course of a month.
