Welcome to our educational video where we delve into the fascinating world of battery management systems! In this tutorial, we'll be using an Arduino Uno to learn about the BQ4050 chip, its functions, and the critical role it plays in safely managing lithium-ion batteries.
🔌 Topics Covered:
Understanding Battery Management Systems
Exploring BQ4050 Chip Functions and Features
Learning about Cycle Count, Full Charge Capacity, and Design Capacity
Communication Protocols: I2C, SMBus, and More
Responsible Approach to Learning and Experimentation
💡 Please Note:
While we're excited to explore battery management with you, we want to emphasize the importance of responsible learning. Modifying battery management systems without proper knowledge and authorization can lead to safety hazards, damage to devices, and even legal consequences.

Excellent
Thanks for sharing the knowledge
Thank You
Thanks for your support ❤️❤️
Is there any differences in terms of capability between using arduino and cp2112? I have this chip in my laptop battery and change one of its cells because its broken. Thx, great content btw.
great videos thanks for it.please make videos on maxim ic,s also RJ chips like r2j240 i hope you fix our this problem soon
Thanks for your support, i have only a 51f51 chip with me. Still trying to enter bootmode. Anyway if i get hands on ev2400 i can try to unlock these chips. But it will take time. With cp2112 very hard to unlock, because there is no documentation available.
You nailed it again!!
Thanka for your comment bro ❤️
thanks alot
but ive one question
why ican modify all parameter in bq 40z50 except cycle count would never change?!!!!!
With full access mode only some parameters can be changed with this software. If you need more options, you need to use bq studio or other professional tools, but those only support ev2300 or ev2400. So if you want to change only cells, , do recell and dumb and upload eeprom, it will clear errors and do cycle count change and full charge capacity. Other parameters can't be simply changed, it needs more information and knowledge.
Hi, I have a laptop battery with the SH79F329, I think it's blocked but i need to read the data to be sure. Is it also working with this one ? I just discover your work, it's really great!
Do you have any tool to read the data?
Sorry for late reply
@@AnandakrishnaSudhakaran I have some microcontroller board like Arduino or ESP32. I also have some SERIAL to USB converter, if it can help.
sorry for my VERY late reply
From where can I buy this tool?
what is Known unseal key for qb20z90
best wishes
I tried in bq8050 everything went well but the unseal key isn't working. The chip is from 2011 year.please help me. Can you know all the possible key?
watch my bq8050 video
after replacing cells pack does not have output
what parameter should i change to get it back in work?
thankx in advanced
Which chip ? Did you restore rom?

hej can you help me find right file for my HP laptop battery (bq20Z75)to use same method as you didi .thanks
If its use sha1 method or if the keys are default you can try this method, for normal unlock use bq9003 and try unseal and for sha1 method choose bq30z55 and click unseal
@@AnandakrishnaSudhakaran iwant just to unseal bq20z75 which i have in my battery with arduino that i have tell me just what i need for files thank you very much.
can you make video to unlock and rewrite bms drone fimi with ic 6003-001 NQ97P
Pls check chip number again? Is it 6003 or 9003? For drone I saw 9003, 6003 is not on the software. If you can pls send a photo on my telegram, insta or discord . So i can ask my friends. Also i will share a drone group. They mainly unlock bq 9003,bq9006 and bq30z55.

hello, I can’t unlock 045A20 in any way, battery from lenovo x1 carbon
What is the chip number? I am not finding any details with this number. Thank you for your comment
its R2j240 045a20 its LGC chip family@@AnandakrishnaSudhakaran
first thanks for replaying ,my hp battery connector is like that ++, ++, SDA, SCL, ??, T, -, - but its give me error no SMBus device found .i switch the pin data with cklock and not working any idea?

can i use arduino nano for this project
Yes
Brother I tried uploading code to my esp32 but this error occurr
Compilation terminated avr/wdt.h not found
No such file or directory please help
i will check and reply
I think avr/wdt.h library is missing can you provide it or till will not work for esp board
I define the correct SDA/SCL pin according to esp32 board but I think it's compilation error

please make a video on all these chips how to clear its PF and reset FCC?
Once again thanks for your support. With the free software and free resources I cannot make anything with my knowledge. But I am trying every day to make something for the community for free, So it will take some time, also iam limited to hardware setup. New video is coming with UBRT free software. Waiting for my usb to lpt converter to come.
make video on bq40320
Hi, How to unlock a chip while not knowing unlock key? Thanks
First try all common keys available on the internet. And there is no universal way to enter boot mode. Free tools are not offering easy unlock. Because nobody knows the correct way of unlocking. So at this point we need to use other paid software which supports the unlocking of your chip.
what is the unseal key for "045A20 SANYO chip"?
Sorry, I don't have this chip. did you search on google?
@@AnandakrishnaSudhakaran I was searched many time, there is no such information about the chip. But this chip is mostly used in Lenovo Ideapad 320/330 laptop battery.
@@akibhosenkhan4217 There is a method to reset. but not documented. Do you have any board to check the chip? Like cp2112 or ev2300
@@AnandakrishnaSudhakaran I don't have those board. By the way , your last part in this video, you hints a software called UBRT. Please make a details video about this, and also your DYI device .
@@akibhosenkhan4217 UBRT REGEDIT is a professional software, which works with ev2300, LPT to I2c and usb to gpio. Do you have arduino board?
Esp32 can be used instead of adruino ?
I will check and reply to you. Thanks for your comment.
Hello there, on the arduino code on the first part where the i2c pins are defined, you can add the required pins for the sda and scl. Then upload the code to esp32 and check with the GUI.
Ok I try and comment if it works
Full access default key is same for all chips or not
@@MYSTRIFACT on tht github link check wiki section there are some keys showing. Try that also
waitiing for your software which support MAXIM chips and R2j240 chips hope it works
Hey thanks for your support. Maxim and R2j240 are still on the list. Am trying to buy a ev2300 for further study. Am saving some money for it. Also I am trying to unlock 51f51 which is almost the same as this r2j240.
@@AnandakrishnaSudhakaran I hope you will be able to unlock the chip R2J24051F021A. We are waiting for a new video on unlocking the chip R2J24051F021A
Thanks for your support, unfortunately i dont have that chip with me now. But if you need any assistance i can give you. Feel free to contact me on instagram or telegram

excellant job
hard work
it works for me on one battery but not other types
Ques:
what is Known unseal keys other than 0414 3672 ?
Thanks A LOT
Thanks for your support. These are the default keys, otherwise we need to do a deep research about the chips. What are the other chips numbers? So i can find if any keys available.
