Other Parts Discussed in Thread: BQSTUDIO,
Hi!
I’m experiencing an unexpected behavior when using the battery fuel gauge. It seems to measure current in the wrong direction, making the SOC calculation all backwards. For instance, the SOC value decreases during charging and then increases when discharging the battery.
The average current and power registers show accurate (amplitude) positive numbers when running on battery and negative numbers when charging the battery. The battery is connected to the BAT pin (C3) and the charger and system voltage connected to the SRX pin (C2).
Have our hardware team got the design wrong, or am I missing some critical configuration from the software side? I’m using the default settings since the should be close enough to our battery.
Can anyone please advice on how I shall proceed.
Best regards,
Oscar
