BQ27542EVM: Ambient temperature of 45°C, SOC% error

Hello,

Your question has been assigned and will be reviewed when possible. In the meantime could you attach the .log and .gg files associated with the project.

Thank you,

If everything is tuned correctly (including load prediction - the answer depends on how accurate the load prediction is, which also depends on the load), then we can typically achieve +/-3 percentage points reports SOC - true SOC calculated after the discharge/charge (using measured coulomb count and total passed charge).
