Uninterruptible Power intelligent Supply Module

Suspicious Status information

Postby SlySven » Tue Jul 05, 2016 11:07 pm

I have a UPiS Basic {Hardware Release: "VC02", running the original 1.00 firmware - I do plan to upgrade - at least when 2.0 comes out :D ) and I was recently testing something and found some odd behaviour.

I had written a daemon that continuously monitors the UPiS over serial port - it polls it with a "@STATUS" command every 10 seconds and parses the text coming back. I am using the serial port rather than I2C because I want a dedicated channel to this vital element and I am/will be hanging other things off of the main I2C (currently have a 2 line LCD module with a backpack, other things are to be added). I have just noted though that the status information is consistently saying: "Battery Charger ON" but this does not agree with the "CHG" LED (which is off) and the battery voltage is static. Of particular note is that the displayed current is 0.52A and I have a couple of USB devices (RFID tag readers - for an access control Home Automation project) attached to the RPi - if I remove them the current obviously drops and it is enough for the charger to come on-line so that the nett recorded current raises to around 0.70Amps.

Below I include an edited copy of the values I was parsing from the serial port @STATUS command every ten seconds - for the duration of this test power was applied to the USB power input of the UPiS, from a 3.5A buck converter with a 3300uF 10V capacitor so the voltage surges reported on there should NOT be there IMHO. You may note that my code parses ALL the serial data received including asynchronous notifications of power source changes - the lines including a 10 digit numbers are the slightly process serial data, and the lines without is the detected changes that my code considers:

Around this time I disconnected the 2 USB RFID readers - dropping the current draw a little
Notice the effect on the battery voltage - it is now rising - on the PWB the CHG Led had come ON!:

No change in the connected stuff but for some reason it has switched to battery power, though that USB input looks a bit high?

After cleaning up the about for inclusion I took another single sample, with the USB RFID devices
still attached, the STATUS dual-LED was flashing as normal (green twice a second, red every ten seconds
- the latter as the serial port is used I believe), CHG is OFF, BAT is ON, USB is ON.

All in all - I do not believe the "Battery Charger ON" reporting...

[EDIT:]Questions:
A): Is there OVER-voltage protection on the UPiS USB power input? If it gets too HIGH, say 5.25V(?) does the UPiS disconnect and switch to BAT mode - I set my digital multi-meter (in "MAX" recording mode) and noticed that in a repeat of the above sort of situation the incoming supply (from MY circuitry, so MY problem) is not quite as tightly regulated as I thought. :(

B): If the answer to A: is YES - what is that limit (in volts) and where is it measured - I guess this would be down-stream of the Input PolyFuse "F1" so there will be a small voltage drop across that as well - looks as though it might be taken from the junction of R6 and R8.

C): Completely unrelated - I have a "Basic" model - so it does not have an EPR - but can I populate a few SMD components and access / use the ADC used to "monitor" the EPR input (but without ANY SWITCHING components) for a separate purpose? This would be to monitor an external 13.8V battery that will be the upstream UPS for the WHOLE of my project - including the 13.8V to 5.x Volt converter supplying the UPiS USB input - or WILL A SIGNIFICANT VOLTAGE ON THAT UNUSED SENSOR CAUSE ABNORMAL OPERATION ON A "BASIC" AS THE SOFTWARE TRIES TO SWITCH TO A SUPPLY THAT ISN'T THERE?

Further cogitation on the meaning of text passed via the serial interface: do the following messages in the UPiS Version 1.00 firmware:
Code: Select all
Battery Charger ON

Code: Select all
Battery Charger OFF

actually mean:
  • "the charger is ENABLED and might charge the battery if conditions permit"
  • "the charger has been DISABLED and will not charge the battery at all"
respectively? So that even if one has got the "Battery Charger ON" message it does not mean that charging is actually taking place, just that that charger is allowed to operate. Is there any way to detect the state of the "CHG" LED via the serial port or is that information not available via that interface?

Has that changed in a later firmware version e.g. so that there might be THREE messages:
Code: Select all
Battery Charger ON

Corresponding to CHG LED lite.
Code: Select all
Battery Charger IDLE

Corresponding to CHG LED off, but charging is enabled (e.g. after a "@CHGR ON" following a previous OFF command)
Code: Select all
Battery Charger OFF

Corresponding to Charger DISABLED (with a "@CHGR OFF" command...)

I wish to monitor the status of my RPi Home Automation project remotely and one thing that I really ought to keep an eye-on is whether the UPiS is: charged up and ready or it is recovering from a power outage (obviously if it is powered down that is a whole different detection system :lol: ). Monitoring the battery voltage is already in hand but to make sense of that you do need to know whether there is energy being put into battery. :P

Hello? Not so much a *bump*, but at least a gentle *nudge* - is there anyone there? ;)
