| 11 | |||
| 12 | * new parameter that sets the delay before measuring the current to determine that precharge is finished (see the "Control - Precharge" section) | ||
| 13 | * ability to exclude errors from being saved in the error journal (see the "Service - Errors journal" section) | ||
| 14 | * new flags indicating the readiness of battery modules to join for charging and discharging (see the "Modules" section) | ||
| 15 | * 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) | ||
| 16 | * Unibat: new parameters setting the BMS and VCU addresses (see the "External equipment - Unibat vehicle" section) | ||
| 17 | * Unibat: new flag to invert the discharge current limit sent to the vehicle (see the "External equipment - Unibat vehicle" section) | ||
| 18 | * Unibat: using the difference between the maximum and minimum temperatures among all cells as an input for the coolant pump controller | ||
| 19 | * Unibat: automatically switch from discharging to charging mode if the CHARGE_ON signal or the charging station command is set (without rejoining the battery) | ||
| 20 | * 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.) | ||
| 21 | |||
| 22 | == Fixes == | ||
| 23 | |||
| 24 | * resolving the issue of ignoring the minimum number of battery modules allowed to join located in the "Control - Discharge" section | ||
| 25 | * 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 | ||
| 26 | * making the service reset function work properly | ||
| 27 | * small internal fixes | ||

| 34 | == Features == | ||
| 35 | |||
| 36 | * 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 | ||
| 37 | * 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 | ||
| 38 | * new Max-Min algorithm for calculating the final battery SOC in the "Control - Calculation" section | ||
| 39 | * 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) | ||
| 40 | * ability to select errors that the device saves in the errors journal (see the "Service - Errors journal" section) | ||
| 41 | |||
| 42 | == Improvements == | ||
| 43 | |||
| 44 | * ability to finish device initialization even if the number of battery modules found is less than the number of modules enabled | ||
| 45 | * ability to configure and monitor the device via the CAN1 (ext) bus | ||
| 46 | * placing the device input signals to the "Battery" section and adding raw discrete inputs to the "Signals" section | ||
| 47 | * Unibat: support for functional description v3.5 (protocol v1.5) | ||

| 52 | |||
| 53 | == Fixes == | ||
| 54 | |||
| 55 | * resolving the problem of incorrect range of temperature parameter values (in the "Control - Coolant pump" section) | ||
| 56 | * resolving the possible problem of saving device parameters | ||
| 57 | * resolving the problem of writing the device's working time to a non-volatile memory very often | ||
| 58 | * resolving the issue of preparing battery module states written to Modbus registers | ||

| 65 | |||
| 66 | * new parameter to set the minimum number of battery modules allowed to join (see the "Control - Charge" and "Control - Discharge" sections) | ||
| 67 | * ability to rejoin battery modules if their voltage is close to the battery voltage (see the "Control - Charge" and "Control - Discharge" sections) | ||
| 68 | * selection of errors that cause reset of contactor control signals (see the "Control - Main contactor", "Control - Charge", "Control - Discharge", "Control - Heater", "Control - Cooler", "Control - Coolant pump" sections) | ||
| 69 | * new internal signal "General error (modules)" which is the logical sum of the "General error" signals from the battery modules | ||
| 70 | * new assignments "Critical error" and "General error (modules)" for the discrete outputs and power switches (see the "Signals - Output discrete signals - Assignments" and "Signals - Power switches - Assignments" sections) | ||
| 71 | |||
| 72 | == Improvements == | ||
| 73 | |||
| 74 | * use the measured voltage before contactors as the battery voltage if the "Control - High voltage" function is enabled | ||
| 75 | * Unibat: new flag to enable sending a control message to start/stop ventilation fans installed in the battery modules (see the "External equipment - Unibat vehicle" section) | ||
| 76 | * rearrangements in the settings sections, which are made to simplify the setup process | ||
