Hello,
I'm struggling with the EOS function of the BQ34110. The communication via an I2C adapter works perfectly fine, the BQ chip is programmable and also the CEDV operates as expected. Despite this success, I cannot get the EOS function working.
The functions EOS_LOAD_ON (0x0044) and EOS_LOAD_OFF (0x0045) switch the load manually on and off.
Manufacturing Status: 0x0057 is 0x001B (PCTL_EN, EOS_EN, ACCHG_EN, ACDSG_EN)
EOS Configuration: 0x4218 is 0x03 or 0x0B (LSM (Discharge before Charge), LENCTL, LTEST (Test Mode, optional)
Learn Discharge Current: 0x4225 is set to approx. the expected value
The lead acid battery is fully charged (Gauging Stauts 0x0056: 0x054A -> FCCX, REST, DSG, TC, FC).
Neither EOS_START_LEARN (0x0039) nor EOS_RCELL_RRATE_LEARN (0x003B) nor PIN_LEN_SET (0x006E) will switch on the load.
Am I missing an important step or dependency so that the EOS function is blocked?
Thank you
Matthias
