Hello,
I am having some difficulty with the new battery management studio interface and the evaluation board for the bq27742. I have created a flash file for a customer pack, but it has been a week now and cannot complete a learning cycle.
I find the management studio interface not as user friendly as the old SMBus interface we use for other gauges/protection ICs. I find the I2C interface buggy and unreliable. I often get flash read errors and checksum mismatches for unknown reasons. There is little information in the EVM user guide on proper configuration of the EVM module and jumper positions in case there is a problem there. The default Ra tables are always populated with -1 whenever I do a chemistry change.
The biggest issue that I am encountering is that when charging cells through the EVM, tapering begins as soon as charge begins, even though the cell is not even close to 4.2V. As a result Qmax never updates. Can somebody please contact me via email asap to work through some of these issues with me.
Thanks,
Joe P.
