JK-BMS Code Generator to Force Updating your BMS for repair and FW downgrade!
Vložit
- čas přidán 14. 06. 2024
- Thanks to one of my viewers, Miro, we have now a working code generator for the new JK Inverter-BMS for Force Updating firmware updates. This Force Updating is necessary if you want to downgrade your firmware, or the BMS got stuck during the update and is now bricked.
In both cases, you had to contact JK-BMS in China and ask for this specific code to enable the Force Updating function in the PC software. It was always a hassle getting this code and entering it in a timely manner into the software because the code expired after just 1h.
Well, this is no longer a problem thanks to Miro's Code Generator which he has hosted on his Github website!
Thanks a lot, Miro, that was a great achievement and contribution to our community!

Big Thanks to Miro! This is AWESOME!
A little information for general clarification:
The codes do NOT work (at least on the new Inverter BMS models, I only have those) to bypass forgotten or incorrectly set settings passwords! These are only for the firmware flash! My PB2A16S20P made a complete mess when setting up for the first time and setting my password and I was completely locked out! ESPHOME in conjunction with an ESP32 and "esphome-jk-bms" helped here. From there, flash the "esp32-ble-example.yaml" (with adjustments to your own BMS) to the ESP. The password set in the BMS is then displayed in the LOG file! The BMS or the software had saved my set password completely reversed... For whatever reason! for example, "123456" became "214365"!
Thanks for sharing and your email as well.

Well I've always wanted to go, but didn't have a place to stay. You think he would let us camp out in his back yard? I've got a sleeping bag and even a tent. Wonder if I can write it off on my tax as a business expense. Technically I have installed solar on RVs for business. I can leave the little woman and kids here. Lol.

MIRO, EXCELLENT! BRILLiANT! SPECTACULAR! Thank you so much...and Andy for all the education I'm receiving. IT'D BE GREAT IF THIS COULD ALSO SOLVE THE WHOLE BT FAILURE TO CONNECT ISSUE JK MUXED UP. I've had 5 BT codes from JK now, and they only last 10-15 minutes, and then my BMSs are locked back up! This going on now 3 months.
This does get into a BT issued BMS, but DOES NOT STICK.
JK, Some us need a PERMANENT BT FIX.
Thanks for the feedback.
Thank Miro, your an absolute ripper mate 👍
JK has got the link on their website now 😄
Cool…thx Miro
You are welcome!
Miro, thank you for releasing this for free. This is how great communities get better.
The force of a community ist strong....🐸🐸🐸
Weather is not looking good for this week down here. Mt Cole fire looks like it will grow this week. Thank you, Miro, for the coding.
Miro is the BOMB! As others have said, My JK B2A20S20P BMS continues to "forget" my password and I had to contact JK everytime I needed to pair with my phone. I would love to hear how to fix the password issue permanently but this is the next best thing.
I am having the same problem, almost every time I need to use it, I think my BMS has got addicted to codes😮
Andyyy du bis einfach spitze!!! Danke für die ganze Videos.
Miro is. He just doesn't have a camera, that's all!
So damn good!!! Thank you Miro and Andy for this!

Heya, that's the beauty of the community that you bilded well done
Thanks for all these amazing videos! What an awesome community you’ve built here! Small question, where do we find the firmwares from JK other than your Google drive? Can’t seem to find any on JK’s website?…
Thank you very much.
JK has only the latest FW on their website. Maybe you are on a fake JK-BMS website? There are lots out there...

JK has got this on their website now😄
Nice that
But still needs a lot of work
Yesterday i switch it off i had made only 4 cycles and after when i connect it again it show me 15 cycles 😂
By the way you are doing very good job
Greetings from sunny Greece
Thanks a lot my friend from beautiful Greece!
And will work so long as JK build a new Firmware, i believe they will change "calculation" of it 🎉
The code check is entirely made in the PC Software. So even with a new firmware it will work. If they change the algorithm in the software, you could still use the current version
@@mirofromdiro Yes Miro, you did a great job. I am fine and gratefull regarding your findings.

Many thanks for the content of your channel. It’s still so interesting. you encouraged me to replace my 2 bms with the new JK bms. I have just installed them, and I am having a small problem with the monitor on my PC. when I launch the program, only the "parallel" tab is active, the others are grayed out. The data for my 2 battery packs are ok, but I can only configure the BMS via the Bluetooth application. I had to force the firmware update with Miro's code. What do you think ?
thanks in advance,
What if you connect only one BMS with DIP set to 1000?
@@OffGridGarageAustralia
I did this with the 2 BMS separately. My problem seems to be identical to the one you encountered with your test BMS. The screen display is identical, 2 dials on the left without the data on the right. Did you resolve this issue?
Aloha from Hawaii! I am living off the grid at my farm and have a very reliable PV system consisting of 12 250W 30v panels, a PowMr 5000W hybrid controller, and 2 24v x 100Ah LiFePO4, batteries hooked up in series to give the 48v needed for the PowMr. It is working without any problems except when there is 2 days of bad weather with little or no direct sunlight which runs down the batteries. I want to add an extra 100Ah of 48v battery so that I can weather the 2 days when that arises.. My question is since my original batteries are nearly 3 years old, is there going to be any issues with incorporating new batteries to my system. I really enjoy your channel for your more in depth approach to living with an off grid solar system.
No problem at all. As long as they are all the same chemistry (LiFePO4), the same cell count (8s) and have their own BMS, you can parallel as many as you like, even with different capacities. I've shown this here and in many other videos:
czcams.com/video/bhCSccNsQOw/video.html
Thanks a lot to Miro and Andy. Nobody wonders about this weired behavior of chinese suppliers. I think we need urgently an alternative to these manufacturers.
From where though?
Apexium have new 48V DIY BOX kits with 200A JK Inverter BMS and with smaller 4.3 display, but no breaker as in JK Inverter BMS ELL Box.
I'll get the EEL box and show it on the channel. It seems like a good DIY case.
Awesome. Do you think the new JK inverter BMS is ready for daily use at this point?
it has some issues. Its definately not plug and play. I had to tinker around for a week to get it connected and still have some strange behavior (see my other post)
It seems to work fine. I will set 5 of them soon in my garage and test it.
Absolutely brilliant 🎉👍👍👍👍 bloody BMS locked me out, 2 mins later, solved with the code,👍
Hehehe, well done!
Errm, Huston, I have a problem 🤔 I now need to use the code generator every time 😳 any idea what's going on?🤔🙏
Need more info. When does it prompt for the code?
It was prompting me whenever I tried to connect. I discovered it was because I hadn't reset the password. Since resetting the password it works fine😞 sorry for wasting your time, but it's good to mention, after using the code generator, reset the password 🙄 seems obvious now😊
@@camillabergman2784 Thanks for the feedback. Very helpful.
Well that is quite the thing! Thanks, Miro!
I'm not much for javascript, so I did a quick conversion to Python. I wonder if the order lookup table can be mathematically derived...
I also did it in python first, and than write it in JavaScript for the website. I'll upload the code to GitHub too. And no: the lookup table is hard coded (even in the JK BMS software)
@@mirofromdiro I just had the problem that the password 123456 didn't work with the new BMS. After requesting the temp password (BMS serial number required) it was noticed that only 2 digits were appended to the time-limited "force update code". these 2 digits always remain valid.
I then had the code sent to me for the second one too. maybe these combinations are useful for coding?
Erst liken, dann schauen 😂
Recht so!

Amazing!!!
Hello my friend, I enjoy watching your videos. I have a question regarding both JK and JBD BMS. Do you know if these BMS can be put in series for 48v? For example, i want to split my 48v lifepo4 battery into two separate 8s battery packs each with their own BMS and then connect them in series for 48v. Is it safe? Would it be possible with the 4s BMS to put in series for 48v as well? Thanks for all the work you put in your videos and the information you provide us.
Thank you. What is the reason to split a 48V battery into two 24V batteries and then connect them in series again?
@OffGridGarageAustralia To make the battery easier to carry around. I use it on an electric cargo bike with limited space, splitting the 48v battery into two separate 8s 24v battery makes it easier to fit it on there as well.
@@Fidel55 Ah, right. Never heard of that before... thanks for sharing.
@OffGridGarageAustralia Do you know if it's safe to put those BMS in series for up to 48v? I've contacted different JBD and JK BMS sellers and gotten mixed responses
@@Fidel55 No, sorry, I don't know. Some BMS can handle it others can't. I have no information about it, sorry.
Dachte ich mir doch, dass das nicht lange dauern wird.
Gibt es schon Neuigkeiten zu den noch offenen Problemen mit den neuen JKs. Also z.B. dass über CAN in Richtung Victron nur die Spannungswerte und Temperaturwerte des Akkus angezeigt werden (und da nur die Min/Max-Werte), an dem das CAN-Kabel mit Victron verbunden ist. Ginge über CAN nicht auch noch mehr an Infos? Über RS485 und SerialBattery bekommt man wesentlich mehr an Infos, aber leider auch immer nur von dem einen Akku, an dem der RS485-Adapter angeschlossen ist.
Danke dir für deine Arbeit.
We will soon'ish have a solution for that to connect the new JK Inverter BMS to the CAN to CAN Multiboards, Peter is currently developing. This will connect them via RS485 and we can have the data of all BMS in Victron and HA.
@@OffGridGarageAustralia That also sounds interesting, but then it doesn't seem to be a native CAN. I already have everything in HA via esphome and with serialbattery and RS485 you can also get everything to Victron. But all of this already works with the old JKs. The advantage of the new BMS with CAN connection is somehow lost. I switched from the old JKs to the new ones because I was hoping for simple and secure communication with Victron. But now I have to tinker again and take detours. What a pity
Hello everyone. Hot news. New firmware for hardware v15 is published. Not tested yet.
-V15.11 Upgrade logs
1. DRY Trigger source added "12 - Remote Control "option
2. The LCD V2.0 protocol is added to the protocol library, which supports charging and discharging through the touch screen.
3. The Victor protocol allows the vendor name to be changed by writing the user's private data.
4. Fix a bug, parameters (RFV Time) Storage failure.
Hello: are all JK BMs the same in quality (apart from power (A))?
I'm thinking of getting a BD6A17S8P with LCD and bluetooth, because I don't think I need more than 3/4 kW instantaneously.
Are JKBMS the best? I saw that they are equipped with an active balancer, that seems very good to me. For a lifepo4 16s 48v (51,2) 280ah eve280k battery. Thank you.
Yes, JK-BMS is still the best, I think. The active balancer is great for any setup and will keep your pack balanced.
@Miro,
Great hacking!
Does this work on the older JK BMS's? If so it basically breaks the password functionality. I had to get a code from JK BMS when I couldn't get in to my BMS.
Good question!!
No, it only works with the new JK inverter BMS PB series.
So it's DDMMHHmm (where M=Month, m=minute) for Chinese timezone or UTC?
No, slightly more than that. Check the code.
@@upnorthandpersonalYeah, just looked 👍
Basically ithe algorithm works like this :
- take the current UTC date and hour (so every code valid till full hour)
- add up all numbers
- this sum modulo 10 -> lookup the order
- use this order for the date/time string
@@mirofromdiro Nice work!
I have a JK dp2a16s15p BMS connected to my victron.
but when it goes into float mode there isn't a fixed voltage applied but instead the Battery is charged and discharged all the time with something between 5 to 30 amp every 10 to 20 secs. The discharge is always 0.4 amps lower then charge.
The Soc is also really strange as it jumps from 50% to 100% within 30 minutes of charging in the morning, which can't be true.
Does anyone have the same problem or knows a solution? (my settings in the BMS are close to what andy uses in his)
Got the newest FW installed?
Pretty disappointed didn’t see Andy #2 in his suit beaming in from the newsroom
Hahaha, I know... there was no time of setting something up. Filming, editing and publishing all in one day. Andy2 only delays everything!😄
Will this work on a brand new bms . Or do you need to get the First code from jk
This also works in the app for old bmses that are requiring a code to even show anything.
I was wondering that, so now anyone can bypass the password to our BMS's.
What BMS are that?
@@OffGridGarageAustralia all the old ones that the new app on iOS and android prompt you to even see anything let alone change anything. They all stopped working because the code was some random number. This bypasses and get you in and you can change the password from the scan screen finally.
Absolutely fantastic and great but it would be still a lil better if it is a downloadable keygenerator program.
save the site to your desktop (or elsewhere with rightclick... ) and you get the local keygen website - Thanks goes to MIRO
It's just PHP code, so you cn run it locally.

@OffGridGarageAustralia
I have change my old JK-BMS to the Inverter JK-BMS so far so good. But I think that the 100% full SoC to trigger within only one cell hit the 3,45v are :-( . Can you talk with JK and let use „cell average voltage“. Today we have a bit off sun here in Berlin Germany and the SoC jumps from 80 - 100% and the cell average voltage are max 3,41v.. is this a Diskussion worth? Regards and „Schönes Wochenende“
Average voltage will not work to trigger the 100%. If charging to 3.45V, ALL cells must be at that voltage to have the average at 3.45V too. That would mean 0mV delta across all your cells. Never seen this in any BMS.

Thanks, man!
Hi man what firnware is the one has no errors at all
Das ist der Miaumann der Katze
After i am watching your video i could understand that until now the best solution for bms is not the latest jk version is that correct
I would still say the JK is the best in its class. Due to the ongoing firmware updates, they will get there and solve all issues.

Hi Andy good thing that code is fine Listen I have to the JK A battery must be connected to update it or not because I have connected it to a stabilized power supply I have made the connection to the pc but I can not update it even by entering the brute Force code I have not connected loads or the temperature sensor or I am connected the cables for the display and then the negative and positive of the power supply with the its cable to the positive but Nada is not able to update So I will have to connect it to a battery that I have at home from 16 s280 amp
Power supply is fine, no need for balance cables or connecting it to a battery. It just needs to run for the update.
Maybe you have the wrong fw for your BMS?
