SLUUAQ3A April 2016 – October 2022 BQ4050
The device compares the AFE hardware register periodically with a RAM backup and corrects any errors. If any errors are found during the check, the device increments the AFE register fail counter. If the comparison fails too many times, the device disables the pack permanently.
Status | Condition | Action |
---|---|---|
Normal | AFE register fail counter = 0 | PFAlert()[AFER] = 0 Compare AFE register and RAM backup every AFER:Compare Period |
Alert | AFE register fail counter > 0 | PFAlert()[AFER] = 1 Decrement AFE register fail counter by one after each AFER:Delay Period Compare AFE register and RAM backup every AFER:Compare Period |
Trip | AFE register fail counter ≥ AFER:Threshold | PFAlert()[AFER] = 0 PFStatus()[AFER] = 1 |
