Update

So I finally got the battery box built and wired. Battery box environmental control system is functional.
Still have to work on installing the vent flaps, servos and heaters. But at this time of the year I doubt I will need heaters although at 8°C this AM on June the 1st I'm starting to wonder.
I apologize for the foggy pictures I must have been so excited to get this far this weekend that I was extruding steam Tongue
I will update later with clearer pictures.
Some wire management is still in order but all in all it is functional.


ABB Shunt trip breaker installed but still have to wire the trip to the Batrium.
 
Batrium at its final resting place.

Battery box metrics are sent to influx and visualized with grafana.


I then wanted to get some of the batrium data over to my influx database so I ordered a RasPi and downloaded Daromer's image and played around with it. The image loaded just fine and worked but for me it was a bit too much. I probably will use it in the future if/when I get a decent charge controller but for now my MakeSkyBlues are working just fine.


I just needed a simple UDP listener to port the batrium metrics to influx. Found a sketch for a udp listener that published to thingspeak,
a little code revision here and there got rid of thingspeak and now have the metrics going to influx with a $10 ESP32. 
I will massage the data and metrics ( still have to figure out some of the readings collected) but for now the essentials are being recorded.


That's it for now

Small update:



The battery box environmental control systems are working as programed  Smile
At least so far, winter will tell if the heaters are enough.

What to do when you have too much time on your hands?
Play with Node-Red of course.
So I saw this post https://secondlifestorage.com/showthread...3#pid59143
that Bloater did on Node-Red picking up the Batrium UDP and creating a little dashboard with the cell metrics.

I got his Flow and imported it and checked it out. I must say Bloater did a lot of heavy lifting!!
Now how to get this data and a bunch more into influx..............
A node here a node there, a little code here and a little code there and wella all done.
Now what am I going to do with my spare time Oh yea build another Pack.


Nice day and completely charged!

So I have been running on my powirwall for a month now and looking good.
CDC cycles are looking good Batrium is working good and my electric bill is looking much better. Big Grin

Grid import chart for 60 days
Can you tell when I switched over to my PowIRwall?
Did have a couple of cloudy days and had to have the grid back me up.
Cant wait to get my second pack done.


Metrics for this AM. Making coffee took .07 of a volt for about 15 min.
Nice to see the packs staying very close together even at a discharge.
Not bad for a bunch of used 18650 batteries. 
6hr chart


24hr chart
