Samsung pack always charging

The charger SOC says 99 for many hours
Opening up the bms app charging 0.02a the high & low cells are within limits
Unplug for a day, plug in charge finishes

I haven’t changed any of the settings on the BMS after my initial install
I never did install the spoof
This is my understanding of the settings involved
Without Spoof
ovp to 3.9v
ovpr to 3.85
With Spoof
ovp to 4.05
ovpr to 4.0

I think you may be confused as to what the spoof actually does.

Don’t go to church based on that SOC number. It is a calculation. You really should be looking at voltage. This is what the charger is doing.

What charger are you using?

Thanks for the reply
Yellow stock charger
I understand the approximate nature of SOC reading.
The charger is charging according to the dash & BMS
If I unplug & plug right back in after a couple of minutes, remains 99 charging forever
Unplugged overnight 98 charging finishes
I noticed the always charge [AC] some months ago after longer trips of 20 miles
Every trip now
I drive 3-5 days a week, if I pass by the GEM & see it AC, I unplug, no big
Just trying to keep up with any potential issues

I included the information about the spoof, as it was the only parameter I changed…

The spoof tricks the controller into thinking that the battery voltage is slightly lower to wring the last bit of performance out of the system
I don’t really need the minor increase in range enough to bother :smiley:

No, The charger will do what it is set to do. It can be fudged a bit with the addition of the “Charger Spoof” aka “tweaker” (just to call it something else), but the charger does not take influence from the SOC dash display -nor- the BMS.

Yes and No - The Controller Spoof is added to the Motor Controller and allows it to operate up in the higher voltages that this battery produces. It has nothing to do with the numbers you changed in the BMS app.

The primary role of the BMS is to be a watchdog in case something else upstream goes too far out of spec. You should NOT be going in and adjusting the numbers without knowing what those numbers do.

===== Back to your original query =======

When are you actually observing when you see the 98 and 99?

  • Dash Pod display?
  • App display?

These numbers really do not mean much to anyone here.
Much more accurate info would be to list cellV numbers, total packV, or even show a screenshot of your app Status page.

You also stated above-

What is the Charger Status Panel showing at this time?

2013 e2
SOC shows 99, bar graph counting up every few seconds normal charging routine
Screen goes off when complete charging cycle

Dog sitting I’ll check the bms later
