SoC: None% in log upon driver start

Describe the bug

In my log upon start the SoC is alwaysNone.

After checking the code the variable used for this field is self.soc_calc from battery.py. This variable is set in manage_charge_voltage() but this function is not called before battery.log_settings() in dbus-serialbattery.py. So self.soc_calc defaults to the value defined in __init__ which is None.

How to reproduce

Start the driver and check the log settings.

Expected behavior

The value from self.soc should be visible in the log.
