Battery showing value of max_charge_rate when transiting between discharge/charging #95

Hi,

Have the following battery_config which was working perfectly up until the latest version (about 9 days ago when I installed it)

in this version.- What happens is when the delta is Δ 9.000003046821803e-06 Wh** (aka a very small number) - the charge rate goes to 30kw momentarily

Screenshot 2023-09-17 at 7 49 50 am 10 day charge rate graph; should difference between previous charge rate and "something" changing.

hif2k1 commented 1 year ago

Thanks for getting all the debug info. So the battery is charging and discharging OK its just showing an incorrect charging rate (the maximum possible) is that right? I'll look into it.

yes, the house has 3 phase power; so some of the phases are exporting and some are importing when consumption and production are near evenly matched (not sure how are battery behaves in practice in that scenario). When all 3 phases are exporting all is good; ditto when all 3 phases are importing - during the transition between all phases importing or all phases exporting there is the momentarily spike to max charge rate (being 30kw for my battery sim - Powerplus Escape 30) - haven't been able to exactly pick the exact scenario apart from being around the time of this log entry

2023-09-16 07:35:57.001 DEBUG (SyncWorker_9) [custom_components.battery_sim] (battery_sim: 65.0_kWh_battery) sensor.grid_total_lifetime_import True: 25774.821398 Wh => 25774.821407000003 Wh = Δ 9.000003046821803e-06 Wh

as mentioned; noticed when I installed the latest version; and the 10 day graph shows the noticeable change in the charge rate behaviour. Actually I updated to 2023.9.0 from 2023.8.x around the same time (just to add another variable)

niggles1973 commented 1 year ago

Also, just to double check - Grid Total Lifetime Export is always increasing. anywhere where it looks a little suspect (for instance 8am September 15th) ; I "zoomed" in to a 1 hour view and confirmed that it always increasing.

Sorry I just realised I didn’t specifically answer

So the battery is charging and discharging OK its just showing an incorrect charging rate (the maximum possible) is that right? I'll look into it.

yes; it’s charging and discharging as expected - it’s just the charge rate is wrong (momentarily goes to max charge rate) when there is what looks like charging and discharging during the same delta time period (I think)

hif2k1 commented 1 year ago

Sorry have been a bit snowed under. Will try and get on it asap.

I think I have reproduced the problem in my install. The short answer is that it's a rounding problem.

The long answer: If you zoom right in on the import meter graph does it look something like this with some pattern of alternating small steps and big ones?

image

My meter updates every 10s and is rounded to 0.01kWh. It must be going up roughly 0.02kWh every 30s, but because of the rounding it does 0.01kWh after 10s and then nothing and then another 0.01kWh after 20s. The battery sees this as alternating fast/slow.

Does yours look similar when you zoom in? I can see that it is updating every 10 seconds as well.

The solution could be to update the battery less frequently - say once a minute and accumulate a minutes worth of readings before updating to average out these steps. This would make the battery less real time responsive, but possibly more accurate. Should we go for that do you think?

niggles1973 commented 1 year ago

haven't had a chance to have to have a ponder about this yet ; but ack'ing I have read the above

hif2k1 commented 11 months ago

This should be resolved in the latest release - the battery doesn't update as often which results in a smoother graph
