More DALY smart BMS issues

[Freshwaterdiver1]

Hi, this is the same issue as I have. I have been in contact with daly support and they say that it its necessary to connect the BMS + battery pack to a charger to activate/wake up the BMS. I don´t have a 24-30V charger but I will try to connect the pack-BMS to my solara-arry/MPPT this weekend to see if that can jump-start the BMS.

I have 2. One packed up - no charging and later no power out. They eventually sent a replacement which arrived today, but sadly the PCMaster is showing error, error error . Done all the pre checks 1st of course and i spotted the Resistance was totally wrong.
Hope on hope i connected and tried all ways to boot it up - it eventually showed the cell voltages, but then that disappeared.
Tried reprogramming the voltages to the correct settings but no joy either. They are a pain in the neck when not firing up.
Have started another "Refund please". I used AliExpress. Will's fav store ???
I do have one that worked straight out of the box, easy peasy, and has not let me down so far after 3 month.

It's not actually woke up, there are 2 pins in a socket for the Daly SOC monitor that you have to short together to get it to wake up. I have the same BMS and it did the exact same thing until I shorted the 2 pins with a test lead. I'll dig mine out and get you a picture shorty.

I'm sure the destructions said somewhere that when you plug in the Wifi Dongle, temp sensor or other connector, that will fire it up??. Either way good luck mate - I contacted Daly for advice. But sometimes there is a language comms issue.

Hi, sad to hear that you have problems as well.
When I check the Resistance I get 0,342. This is with the balance-leads connected to the BMS and the battery. So for me that looks good.
The problem with mine is that it will not "Activate". This is still what I hope at least. I will try and connect a 30V 2.5A Power Supply to the BMS this weekend and see if that will wake it up.

Daly 24V 8S Initiation and Software

I'm going to consolidate some of the Daly Smart BMS questions into one thread concerning initialization and parameter setting, some of it I found here in odds and ends, some I discovered on my own. First off, thanks to those who pioneered ahead of me and found ways to get these to work. I...

Applying the charge will wake it up. I just went through this. As soon as you connect, don't forget to go into the settings and change "Sleep" from 3600 something to 65600, otherwise you'll find yourself in the same predicament shortly.

Thanks for your positive feedback. I will keep in mind to change the "sleep" setting if I get it to wake up.

Hi, just tried to apply charge to the battery via the BMS (minus on the charger to P- and plus on the charger to most-positive on the battery). Set the charger to 30V. When I measure on the most-positive and the P- I get 31,1V and when I measure on the most positive and B- I get 26,7V. The battery does not seem to take on any charge since the bench-power-supply says 0,00A. And the BMS will not "Wake up". If I turn off the power supply and measure on the P- and most-possitive on the battery it drops to 1,5V. What can be wrong?
I have the lightboard connected as well as the temp-sensor and the blue-tooth.

Have you connected the Sense wires to the BMS and made sure they are all the way in?
Second, touch the B- to the P- and nothing else.
Third, do not attach the power supply until,the BMS is turned on. There is enough power from the battery to start the BMS.
Fourth, and I know this sucks, but go over the last 86 posts and see if there is something you could have missed.

This is a one step at a time process and is most electrical problems.
Especially with things like Daly that have almost no manufacturer help etc.

Hope this helps

what would 0 do?

You can download the latest PC software here. It is 1.2.8.

The Sleep Time must be set to 65535 (never sleep again). The latest firmware is also necessary to work well with the DALY Smart BMS. My 16S / 250 A Daly Smart BMS works very stable and good with the firmware 20210222-1

One guy did that, and indeed it waited zero seconds before going back to sleep. He did manage to get out of the sleep, but he didn't give details on how.

I recommend avoiding anything under 10 seconds.

I did some more testing yesterday but no success. I have now read thru all the comments in this thread but it did not make me much wiser.
I found this in the comment section on this youtube-post:

Have anyone tried this trick with the Beep-continuity-test on the multimeter?

Have anyone tried this trick with the Beep-continuity-test on the multimeter?

That is the diode test function and basically the same as touching P- to B-

As you have a light board and the port to connect it, this should not be a problem getting the BMS to turn on. Proper installation of balance harness, temp sensor installed, connect balance harness last and light board plugged in. Hit the button and it should turn on.

If it doesn't, then you have an installation problem such as poor connection. Could be balance harness or temp sensor.

 

[ereams65]

Good point on the Temp Sensor because if it's not attached it will create an "error" in the BMS

Looks very interesting. If it works, tell us.
It will be one more tool to getting these dang things working.

what is a light board?

So, I’m back in my off-grid house to do some more testing with the BMS. The Beep-setting on the Multimeter did not do the trick for med. Just says OL and no beep.
So, I read thru the instructions one more time an in step 4 (the step after connecting balance-leads but before connecting B- to batter -) they want you to measure the resistance between the B-and P-. When I do that it I get 0,347 (picture). I am not convinced that I get a good/ok value. I have also taken a picture of the instruction. (The instruction says 0,0 Q-5Q.
What do you think? Is this a OK value?

i just got and installed the 12 volt,250A DALY BMS a week ago.works great.solid runner.will get more.

I never tested the resistance so I have no clue sorry.
You have different instructions than I received.
