132 132  * Use specific delays before stopping discharging (on errors) – a flag to enable manual settings of time delays T,,off,, for specific errors;
133 133  * Switch off the discharging relay on errors without delay – a flag to protectively open the discharging relay without delay. In the opposite case, when an error is detected, the discharging relay opens always with the delay “Delay before stopping discharging”.
134 134  * Precharge time – a duration of closing the precharge relay before closing the discharging relay, millisecond;
135 +* Precharge current threshold to start discharging – a minimum current value to finish precharging and start discharge, A;
135 135  * Voltage to clear the “Ready to discharge” signal – a threshold voltage level on the cell, V; if the voltage of any cell is below this level, the “Ready to discharge” signal is cleared;
136 136  * Voltage to reset the “Ready to discharge” signal – a tolerant voltage level on the cell, V; if all cells voltages are above the tolerant level, the “Ready to discharge” signal is set.
