The calculation of the charge, discharge and regeneration currents of the entire battery is performed based on the number of battery modules operating for charge or discharge and the maximum charge and discharge current values ​​transmitted by them:

304 +* Enable – a flag to enable battery charge/discharge controller;
305 +* Mode:
306 +** Dependent - Charge/Discharge contactor depends on Charge and Discharge algorithms and their signals;
307 +** Independent - Charge/Discharge contactor is based on its own controller.
308 +* Algorithm:
309 +** Always on – discharging is always allowed;
310 +** Balanced – discharging is allowed provided that all battery modules are balanced;
311 +** Partially balanced – discharging is allowed for most balanced battery modules;
312 +* Minimum number of modules allowed to join – a minimum number of battery modules that can be connected in parallel;
313 +* Allowable battery current to rejoin modules – a battery current at which joining of battery modules is permitted, A;
314 +* 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;
315 +* Checking voltages time – a time of checking voltages of battery modules before starting joining modules, millisecond;
316 +* Balancing modules time – a time of balancing battery modules after joining modules and before closing main discharging contactor, millisecond;
317 +* Control the precharging contactor – a flag to control the main precharging contactor;
318 +* Canceling discharging time – a delay before opening the main discharging contactor, millisecond;
319 +* Disconnect modules that are not ready to charge – a flag for disconnecting modules that have the “Ready to charge” signal cleared;
320 +* Disconnect modules that are not ready to discharge – a flag for disconnecting modules that have the “Ready to discharge” signal cleared;
321 +* Join modules on the “Charge request” signal – a flag to enable automatic modules joining if “Charge request” signal appears;
322 +* Join modules on the “Discharge request” signal – a flag to enable automatic modules joining if “Discharge request” signal appears;
323 +* Maximum charge current limit – a maximum allowed charging 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 charging/discharging contactor – errors that cause the main charging/discharging contactor "Discharging" to open,
327 +* Switch of the charging/discharging contactor on errors without a delay – a flag that allows the main charging/discharging contactor to be opened without delay if errors are detected.
