BQ28Z610: Why is BMS blocking charging?

Vojtech Glombícek

Part Number: BQ28Z610
Other Parts Discussed in Thread: EV2400

Tool/software:

Hello, I'm having a problem with the bq28z610 BMS chip. It doesn't open the charging FET and I couldn't find any command for it.

Because I don't have the EV2400 USB bridge, I used this arduino sketch instead to read the BMS: https://github.com/asilichenko/bq28z610-arduino-driver

Here is the output:

In the readout, it says that the battery is fully discharged. This doesn't make sense to me as the battery is at mid-charge voltage. Also, if it's discharged, shouldn't charging be enabled?

Hello,

Have you successfully completed the learning cycle? How was your chemID matched for the cells you are using, did you use the GPCHCEM tool?
