NOCO genius5 not charging PowerBoost

[Shane150]

I connected this to the truck last night and it started blinking the first light. This morning after nearly 12hrs it is still blinking the first light. Is this charger not strong enough or there are other issues at play?

Have you tried getting that black negative clamp onto the negative battery terminal itself?

 

[Snakebitten]

I think he actually has it connected properly for the BMS to account for the charging current going to the battery.
And there isn't a "strength" requirement for the charger. Many of us use the same charger to charge our AGM.

Do you have it set for AGM?

Edit: I see that you do.

Just for clarification

Yeah not saying it’s wrong. Just trying to troubleshoot the issue. My thought was to 100% guarantee it’s getting juice to the battery by connecting directly to the battery post. Just removing a touch point for the charger I guess.

You could also enable Force Mode by holding Mode button for 5 sec. Supposedly that will allow charger to start charging a heavily depleted battery.

I think the power to the charger was on when I made the connection. I will retry correctly this evening. Thank you!

Will try that if everything else fails. Truck is working fine. I have just been driving very short distances for the past month and I thought it doesn’t hurt to charge it. It is also getting cold in my area.

That was probably the issue.
They are smart little devices and have a lot of failsafes built in.

Good luck

Are you saying the BMS is designed to measure current flow while the vehicle is in the “OFF” state? Genius. Does the HVB continue to feed the DC/DC converter? Can it fire up the ICE? If the answer is no to the last two questions, then it’s just wasting energy to monitor itself. It’s a vampire because it can’t do anything with the data it’s collecting except waste more energy to tell Ford Pass it’s shutting down features due to sucking the battery dry lol.

There is by the way a very long thread on SOC and BMS with a lot of valuable information from @Snakebitten but unfortunately I haven't had the time to go through it all.

The DC/DC converter activity, while the truck is off, isn't something I know enough about to guarantee that it can not be in use under any circumstances.
But the BMS being alive/awake and capable of measuring the current passing through that post mounted shunt? I think it's very likely that some portion of the LV activity is more than just the occasional TCU polling.

Below is the same screenshot twice. It's the 12V static voltage for yesterday as my Powerboost sat undisturbed.
I captured it twice so that I could include the time marker early in the morning and late at night.

You can also zoom in and see the pretty much constant voltage fluctuations, which overall trend downward, as you'd expect.
1:39AM = 12.84V

By 11:09PM it was 12.72V

Do these trucks really ever sleep?
At least prior to some threshold where the BMS intervenes and forces a "deep sleep"?

And how could it (BMS) monitor the voltage and intervene if it wasn't awake to do so?

That thread is for folks that don't have a life. ?

Do you sleep? Just curious.

Also, I cannot see that on a non-powerboost the difference in charging with hvac 5+. I can turn the hvac off and it still maintains the 12v system at 14.5v+.
