6 += v3.7.0 =
7 +
8 +[[BMS_Main_3X_v3.7.0.bin>>FileManager.BMS_Main_3X_v3\.7\.0\.bin]]
9 +
10 +== Features ==
11 +
12 +* 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)
13 +* new total charge counters (plus and minus)
14 +
15 +== Improvements ==
16 +
17 +* Unibat: new flag to set the custom value (=3) for the EESCD signal (see the "External equipment - Unibat vehicle - General parameters" section)
18 +* Unibat: new bit field to ignore internal errors that cause battery shutdown (see the "External equipment - Unibat vehicle - General parameters" section)
19 +* Unibat: sending a new packet containing the continuous charge current limit
20 +
21 +== Fixes ==
22 +
23 +* optimization of the logging process, minimizing the time to open the next log file if the current one is full
24 +* resolving the stability problem when the SD card is full
25 +* Unibat: prevent sending module online statuses if the power down condition is met
26 +* Unibat: small fixes
27 +
28 += v3.6.2 =
29 +
30 +[[BMS_Main_3X_v3.6.2.bin>>FileManager.BMS_Main_3X_v3\.6\.2\.bin]]
31 +
32 +== Improvements ==
33 +
34 +* turning on power switches with a delay of 1 second after reaching the supply voltage of 9V
35 +* Unibat: new flag that allows to hide the insulation testing status when repeating measurements (see the "External equipment - Unibat vehicle" section)
36 +* 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
37 +
38 +== Fixes ==
39 +
40 +* resolving the issue of false warnings indicating that the battery current exceeds the current limits (affects Unibat vehicle)
41 +* 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)
42 +* Unibat: resolving the issue of TP messages not being sent if the transport is already transmitting something at the time of the request
43 +* corrections of typos in parameter descriptions
44 +
45 += v3.6.1 =
46 +
47 +[[BMS_Main_3X_v3.6.1.bin>>FileManager.BMS_Main_3X_v3\.6\.1\.bin]]
48 +
49 +== Improvements ==
50 +
51 +* 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)
52 +* new flag allowing to swap CAN2 (int) and CAN3 (BMS) interfaces (see the "Connectivity" section under the service account)
53 +
54 += v3.6.0 =
55 +
56 +[[BMS_Main_3X_v3.6.0.bin>>FileManager.BMS_Main_3X_v3\.6\.0\.bin]]
57 +
58 +== Features ==
59 +
60 +* Unibat: refined algorithms and new parameters to meet requirements of version 8.5 of the logic (protocol v6.1)
61 +
62 +== Improvements ==
63 +
64 +* new flag enabling fast current measurements (see the "Signals - Current sensor" section)
65 +* new parameters to ignore the specified errors when setting the critical error (see the "Protections - Critical error" section)
66 +* displaying HV calibration values for the service account (see the "Service - Calibration" section)
67 +* Unibat: structuring parameters into subgroups: "General parameters", "Battery parameters", "Diagnostic parameters", "Power limiting parameters", "Battery version" (see the "External equipment - Unibat vehicle" section)
68 +
69 += v3.5.0 =
70 +
71 +[[BMS_Main_3X_v3.5.0.bin>>FileManager.BMS_Main_3X_v3\.5\.0\.bin]]
72 +
73 +== Features ==
74 +
75 +* support for sending battery state and events via MQTT protocol via Wi-Fi or cellular network (see the "Service - MQTT" section)
76 +
77 +== Improvements ==
78 +
79 +* support for secure (TLS) connections in BMS GSM v1 and v2 drivers
80 +
81 +== Fixes ==
82 +
83 +* synchronization of the precharge procedure with the charge/discharge algorithms, so that precharge is stopped if charging and discharging are prohibited
