305 -* Enable – a flag to enable the charge/discharge controller.
306 +* Enable – a flag to enable battery charge/discharge controller;
307 +* Algorithm:
308 +** Always on – discharging is always allowed;
309 +** Balanced – discharging is allowed provided that all battery modules are balanced;
310 +** Partially balanced – discharging is allowed for most balanced battery modules;
311 +* Minimum number of modules allowed to join – a minimum number of battery modules that can be connected in parallel;
312 +* Allowable battery current to rejoin modules – a battery current at which joining of battery modules is permitted, A;
313 +* Allowable voltage difference to rejoin modules – a difference between the voltage of the disconnected module and the battery voltage at which its joining is permitted, V;
314 +* Checking voltages time – a time of checking voltages of battery modules before starting joining modules, millisecond;
315 +* Balancing modules time – a time of balancing battery modules after joining modules and before closing main discharging contactor, millisecond;
316 +* Control the precharging contactor – a flag to control the main precharging contactor;
317 +* Canceling discharging time – a delay before opening the main discharging contactor, millisecond;
318 +* Disconnect modules that are not ready to charge – a flag for disconnecting modules that have the “Ready to charge” signal cleared.
319 +* Disconnect modules that are not ready to discharge – a flag for disconnecting modules that have the “Ready to discharge” signal cleared.
320 +* Disconnect all modules if one is not ready to discharge – a flag for disconnecting all modules if one of the modules have the “Ready to discharge” signal cleared;
321 +* Disconnect all modules if one is not ready to discharge – a flag for disconnecting all modules if one of the modules have the “Ready to discharge” signal cleared;
322 +* Join modules on the “Discharge request” signal – a flag to enable automatic modules joining if “Discharge request” signal appears;
323 +* Maximum CONTINUOUS discharge current limit – a maximum allowed continuous discharging current of all the battery, A;
324 +* Maximum discharge current limit – a maximum allowed discharging current of all the battery, A;
325 +* Errors 1 (2) to disconnect all battery modules – errors that cause all battery modules to be disconnected from the common bus;
326 +* Errors 1 (2) to open the discharging contactor – errors that cause the main discharging contactor "Discharging" to open,
327 +* Switch of the discharging contactor on errors without a delay – a flag that allows the main discharging contactor “Discharging” to be opened without delay if errors are detected.
