1) "Discharging off" state.

In this state, the discharging contactor is open.

If all the conditions are met:

• the charger is disconnected;
• the charging contactor is open;
• the “Critical error” is cleared;
• the "Undervoltage" error is cleared;
• the "Overcurrent" error is cleared;
• the "High temperature" error is cleared.

If, after T = 10 seconds, the difference is |Voltage A2-Voltage A1| < “Delta voltage (tolerance)”, then the transition to the state "Load connected". If after the expiration of the time T the difference |Voltage A2-Voltage A1| > “Delta voltage (tolerance)”, then the transition to the "Crown error".

• the charger is connected;
• the “Critical error” is generated;
• the "Undervoltage" error is generated;

In this state, the discharging contactor is still closed and at the same time the battery voltage is not output to the A2 line.

After T = 10 seconds, the transition to the "Load Off" state if performed.

5) "Crown error" state.

In this state, the discharging contactor is open and the "Crown error" is generated. If the "Inhibit discharging on the EWS signal" is not set, then after T = 10 seconds, the "Crown error" is cleared and the transition to the "Discharging Off" state is performed.
