RELAX mode occurs when the CC1 current measurement falls below the SLEEP threshhold set in the Settings:Configurations:Power Config[SLEEP] register. When in RELAX mode, there are three important registers which control balancing that the user needs to configure.
- Cell Balance Min Cell V: This register
sets the voltage value where if the battery is not charging or discharging, cell
balancing is disabled.
- Cell Balance Min Delta: When not charging
or discharging, this register holds the maximum allowed difference between the
highest and lowest cell voltage before automatic cell balancing begins.
- Cell Balance Stop Delta: When balancing in
RELAX mode, this register holds the smallest possible delta between the highest
and lowest cell voltages. Once the measured delta is smaller than the register
value, the balancing stops.
