| 10 | == Features == | ||
| 11 | |||
| 12 | * new algorithm in the Charging/Discharging controller that allow to control the Charging/Discharging contactor independently from the Charging and Discharging signals (see the "Control - Charge/Discharge" section). The new "Independent" algorithm is preferred in the battery systems with one contactor | ||
| 13 | * new "Need acknowledge" warning signal that is set when a new record is created in the errors journal. The signal can be cleared in the "Service - Errors journal" section | ||
| 14 | * new Max-Min algorithm for calculating the final battery SOC in the "Control - Calculation" section | ||
| 15 | * improved control of the precharging contactor, which can precharge capacitive load using multiple attempts and detect high power dissipated in the precharge resistor (see the "Control - Precharge" section) | ||
| 16 | * ability to exclude errors from being saved in the error journal (see the "Service - Errors journal" section) | ||
| 17 | * ability to restart the device according to a specified schedule at the moment when the battery system is preparing to charge | ||
| 18 | * new error "High contactor temperature" that can be used to open the specified contactor to prevent it from overheating (see the "Protections - High contactor temperature" section) | ||
| 19 | * new internal signal "Coolant pump" that can be assigned to a relay or discrete output (for signal settings, see the "Control - Coolant pump" section) | ||
| 20 | * new flags indicating the readiness of battery modules to join for charging and discharging (see the "Modules" section) | ||
| 21 | * new flag to set the "Voltage unbalance" errors for battery modules that are not ready to charge or discharge (see the "Protections - Voltage unbalance (in any state)" section) | ||
| 22 | * initial support for Pylontech inverters | ||
| 23 | * extension of the CANopen dictionary to provide additional information for the BMS Display (device serial number, battery serial number, battery address, Wi-Fi and LAN addresses, SOH, capacity, etc.) | ||
| 24 | |||
| 25 | == Improvements == | ||
| 26 | |||
| 27 | * ability to finish device initialization even if the number of battery modules found is less than the number of modules enabled (see the "Control - Modules" section) | ||
| 28 | * placing the device input signals to the "Battery" section and adding raw discrete inputs to the "Signals" section | ||
| 29 | |||
| 30 | == Fixes == | ||
| 31 | |||
| 32 | * resolving the issue of ignoring the minimum number of battery modules allowed to join located in the "Control - Discharge" section | ||
| 33 | * resolving the issue of joining battery modules the number of which must be greater than or equal to the minimum value specified in the settings | ||
| 34 | * small internal fixes | ||

| 55 | |||
| 56 | == Fixes == | ||
| 57 | |||
| 58 | * resolving the issue of preparing battery module states written to Modbus registers | ||
| 59 | * resolving the problem of writing the device's working time to a non-volatile memory very often | ||
| 60 | * resolving the problem of returning error states when saving device parameters (mainly via Wi-Fi) | ||

| 66 | == Features == | ||
| 67 | |||
| 68 | * new parameter to set the minimum number of battery modules allowed to join (see the "Control - Charge" and "Control - Discharge" sections) | ||
| 69 | * ability to rejoin battery modules if their voltage is close to the battery voltage (see the "Control - Charge" and "Control - Discharge" sections) | ||
| 70 | * selection of errors that cause reset of contactor control signals (see the "Control - Main contactor", "Control - Charge", "Control - Discharge", "Control - Heater", "Control - Cooler" sections) | ||
| 71 | * new internal signal "General error (modules)" which is the logical sum of the "General error" signals from the battery modules | ||
| 72 | * new assignments "Charging", "Precharging", "Discharging", "Charging/Discharging", "Main contactor", "Critical error" and "General error (modules)" for the discrete outputs (see the "Signals - Output discrete signals - Assignments" section) | ||
| 73 | * new assignments "Critical error" and "General error (modules)" for the relays (see the "Signals - Relays - Assignments" section) | ||
