9 +
10 +== Features ==
11 +
12 +* support for the Trolleybat vehicle (see the "External equipment - Trolleybat vehicle" section)
13 +
14 +== Improvements ==
15 +
16 +* checking the continuous charge current limit only if the "Use continuous charge current limit" flag is set in the "External equipment - Unibat vehicle - General parameters" section
17 +* Unibat: transition to charging mode according to the condition EESCD=7
18 +
19 +== Fixes ==
20 +
21 +* resolving the problem of completing the initialization process before the power switch voltage stabilizes
22 +* Unibat: prevent the "Charge request" and "Discharge request" signals from being reset if the Unibat vehicle goes offline (the signals are controlled in the Unibat state machine)

29 +
30 +* Unibat: do not send the insulation error DTC if the IMD goes offline when the battery system is in the shutdown mode

35 +
36 +== Features ==
37 +
38 +* new profile section with global battery status, which includes total charge and energy counters, total operating time, contactor opening count, etc. (see the "Profile" tab in the Unified monitor)
39 +* new total charge counters (plus and minus)
40 +
41 +== Improvements ==
42 +
43 +* Unibat: new flag to set the custom value (=3) for the EESCD signal (see the "External equipment - Unibat vehicle - General parameters" section)
44 +* Unibat: new bit field to ignore internal errors that cause battery shutdown (see the "External equipment - Unibat vehicle - General parameters" section)
45 +* Unibat: sending a new packet containing the continuous charge current limit
46 +
47 +== Fixes ==
48 +
49 +* optimization of the logging process, minimizing the time to open the next log file if the current one is full
50 +* resolving the stability problem when the SD card is full
51 +* Unibat: prevent sending module online statuses if the power down condition is met
52 +* Unibat: small fixes

55 +
56 +[[BMS_Main_3X_v3.6.2.bin>>FileManager.BMS_Main_3X_v3\.6\.2\.bin]]
57 +
58 +== Improvements ==
59 +
60 +* turning on power switches with a delay of 1 second after reaching the supply voltage of 9V
61 +* Unibat: new flag that allows to hide the insulation testing status when repeating measurements (see the "External equipment - Unibat vehicle" section)
62 +* expansion of the list of parameters that are reset to default values when the device is powered on while holding the button on the board. The following parameters are affected: all CAN1 (ext) settings; all CAN2 (int) settings; all CAN3 (BMS) settings; all RS-485-1 (Modbus) settings; LAN settings: IP mode, IP address, Netmask, Gateway address
63 +
64 +== Fixes ==
65 +
66 +* resolving the issue of false warnings indicating that the battery current exceeds the current limits (affects Unibat vehicle)
67 +* Unibat: changes that make it so that the output period is responsible for only 4 messages, not for all messages (see the "External equipment - Unibat vehicle" section)
68 +* Unibat: resolving the issue of TP messages not being sent if the transport is already transmitting something at the time of the request
69 +* corrections of typos in parameter descriptions

72 +
73 +[[BMS_Main_3X_v3.6.1.bin>>FileManager.BMS_Main_3X_v3\.6\.1\.bin]]
74 +
75 +== Improvements ==
76 +
77 +* new parameters for switching to the sum of battery modules' currents if the current sensor error is detected or the sensor is saturated (see the "Inputs - Current sensor" section)
78 +* new flag allowing to swap CAN2 (int) and CAN3 (BMS) interfaces (see the "Connectivity" section under the service account)

86 +* Unibat: refined algorithms and new parameters to meet requirements of version 8.5 of the logic (protocol v6.1)
87 +
88 +== Improvements ==
89 +
90 +* new flag enabling fast current measurements (see the "Signals - Current sensor" section)
91 +* new parameters to ignore the specified errors when setting the critical error (see the "Protections - Critical error" section)
92 +* displaying HV calibration values for the service account (see the "Service - Calibration" section)
93 +* Unibat: structuring parameters into subgroups: "General parameters", "Battery parameters", "Diagnostic parameters", "Power limiting parameters", "Battery version" (see the "External equipment - Unibat vehicle" section)
