340 * Balance on charging – a flag to enable module balancing when the battery is charging;
341 * Delta voltage – a voltage difference at which the most charged modules are switched off (those modules whose voltage exceeds the minimum voltage among the modules by the “Delta voltage” value are switched off), V;
342 * Delta current – a current difference at which the most charged modules are switched off (those modules are switched off, the charge current of which is less than the maximum charge current among the modules by the “Delta current” value), A;
Admin 14.1 343 * Detection time – a time for module to be estimated as unbalanced, millisecond;
344 * Waiting time – a time the battery modules are in the disconnected state (after this time, the modules previously disconnected during the balancing process are reconnected to the common bus), second;
345 * Balance on discharging – a flag to enable module balancing when the battery is discharging (if flag is enabled operation logic and settings are equal to balancing on charging);
Admin 1.1 346 * Required discharging current – a value of the discharge current at which the device switches off the most discharged battery modules, A.
