Part Number: BQ40Z60 Tool/software: Hello,
We have long used a BQ40Z60 in our PCBs for charging a 4S4P battery system. This question is in reference to the charge cycle from constant current (CC) to constant voltage (CV) transition and eventually the…
Part Number: BQ40Z60 Tool/software: Hello,
We are curious on how the BQ40Z60 reacts and functions if it wakes up to a cell imbalance. For example, if the unit was stored for a long duration of time and the cells became naturally imbalanced, upon starting…
Part Number: BQ40Z60 Other Parts Discussed in Thread: GPCCHEM Tool/software: Hello,
When performing the learning cycle on the BQ40Z60, the update status doesn't change to 0x06 after the final relax.
The logging shows there's no QMAX update happining…
Part Number: BQ40Z60 Other Parts Discussed in Thread: GPCCHEM Tool/software: Hi everyone,
So, we have a lifetime test for our battery pack, which cycling (charge and discharge) the battery using a randomize RSOC as a target.
At the first time cycle…
Part Number: BQ40Z60 Tool/software: Dear Support, I have a problem during the CV mode when I try to charge a 4S 2P battery at 100%. Indeed, during the end of charge, the voltage is fluctuating and that causes the flag COV to trig. The thing is that we…
Part Number: BQ40Z60 Tool/software: I am using the BQ40Z60 chip and 2 pieces of 18650 batteries in my system. When the batteries are removed while charging, I can detect the removal from the cell voltage. However, when they are removed while not charging…
Part Number: BQ40Z60 Other Parts Discussed in Thread: BQ40Z50 Tool/software: Hello everyone,
We are currently configuring a battery pack using the BQ40Z60. We have successfully completed the learning cycle using the same cells in our 160Wh battery pack…
Part Number: BQ40Z60 Tool/software: Hello,
When testing with the BQ40z60 EVM, I noticed the end-of-charge voltage and feedback pin voltage to be higher then expected.
The datasheet mentions a +/- 2% tolerance on the feedback voltage.
According…
Part Number: BQ40Z60 Other Parts Discussed in Thread: BQSTUDIO Tool/software: Hello E2E Experts,
Good day.
I am working with the BQ40z60 and have an issue with the operation of the Shutdown mode.
The problem occurs when the adapter is tempo unplugged…
Part Number: BQ40Z60
Tool/software:
Hello all,
We have a 4 cell battery based on the BQ40Z60. One of our customers noticed that the charger input pin to some of our battery has the battery pack voltage on in when the AC/DC adapter is unplugged from…
