--* only when the battery is charging (current I > 0) and some time until the battery is relaxed;
++* when the battery is charging (current I > 0) and time after until the battery is relaxed;
  * when the battery is charging (current I > 0) or when the battery is in a state of relaxation;

++A balancing resistor is connected to the cell if the following conditions are simultaneously met:
--* the voltage on the cell is higher than the starting voltage of the balancing;
--* the difference between the cell voltage and the minimum voltage among the cells of the battery is greater than the balancing deviation.
++* the voltage on the cell is higher than the balancing start voltage;
