Battery SOC takes a dive

Post by pss »

I began noticing about 4 days ago my Optics RE would show a battery SOC dive from 100% to 0% and then back within an hour producing a nice deep dip at the same time the green PV bar would shoot up way high from a normal of 0 if this happens during darkness or from the normal daytime output. These PV bar spikes will be from 60-80 kW (my optimal PV for the day now is about 38 kW) while the SOC dive happens, then all is recovered. Has happened in daytime and nighttime. My log chart is basically showing hundreds of entries of every Optic RE parameter that could possibly be recorded. System is actually working fine except for this Optics RE anomaly. Ideas?

Yikes!

"To err is human,
But it takes a computer
to really screw things up"

My default reaction is to think the Mate firmware is corrupt.
Reloading firmware should be low impact and easy to implement.

Next is some sort of issue on the OpticsRE side.
After firmware update, maybe someone on the Optics team can take a peek. Perhaps open a ticket via the ? dialog in the lower left corner.

Finally, a low probability of being triggered by a communications glitch.

Did happened on Sunday morning?
Then is just the DST that an hour is missing in graphs. in one of my system is one hour missing, in the other is just a dip in the stats.

Interesting observation!

I see no discontinuity, but then we don't switch to DST in Hawaii.

I gave up on SOC a long time ago. I still use it for reference and LEDs but I wouldn't use it for programming.

Why? You know why. It drifts. And then maybe it doesn't. Then it does. If you have FLAs you can at least verify the battery status. If you program with SOC you are in for a world of oversight - everything is constantly changing.

They removed the DST here for couple years and then switch it back. The American tourists were getting confused with the time as we are on US EST time zone and keep having to change the time from Miami/New York flight to here in the winter.

A hard reboot of the Mate 3S seems have to restored sanity to my Optics RE display and event log. An Ca we have DST and I wish it were year round. As it is, we are bright and sunny at about 5:30 AM in June and I don't get up that early and then dark before 5 PM in Winter. It would seem that California could simply create its own time zone to follow anyways.

California is in its own zone in so many ways, Time Zone would be a trivial addition.
