When we use the meter chip TI BQ27441DRZT-G1A to measure the power of the battery (1 battery, 18650, 3.6V/3400mAh), we find that the percentage value of the remaining power read from the meter will occasionally measurement data jump:
Phenomenon 1: When the battery power measurement data is read as 14%, connect the charger to charge the battery, and the power measurement data suddenly jumps to 0%. This problem occurs twice;
Phenomenon 2: In the process of battery discharge, the battery power is read as 20%, and then the measurement data suddenly jumps to 0%, which occurs twice.
Tips:
1. The above two phenomena occur on different machines.
2. The actualization parameters obtained from the battery charge and discharge learning have been written into the meter chip before use.Battery charge and discharge learning is conducted using Battery Management Studio.
