82 | State | 0 | Qmax Cell 0 | I2 | 0 | 14500 | 1000 | mAh |
Qmax contains the maximum chemical capacity of the cell profiles, and is determined by comparing states of charge before and after applying the load with the amount of charge passed. They also correspond to capacity at low rate of discharge, such as C/20 rate. For high accuracy, this value is periodically updated by the gauge during operation. Based on the battery cell capacity information, the initial value of the chemical capacity should be entered in Qmax filed. The Impedance Track algorithm updates this value and maintains it.
Before an optimization cycle is run, set this value to the battery cell data sheet capacity. After the optimization cycle is run and for creation of the golden settings, set it to the learned value. The default is 1000 mAh.
