10 == Improvements ==
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

63
64 == Features ==
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
77
78 == Fixes ==
79
80 * Unibat: minor changes in the communication protocol
