@misiak,

1) Each power_supply kernel driver must report time in seconds, so bq27x00_battery too (it convert it).

@joerg_rw, you know bq27200 chip better. Time code was not written by me and now I see from datasheet that chip can report more "time to empty" values (TTECP, MLTTE, STTE, TTE, ARTTE). Which should be reported as "average value" and which as "now value"?
