7 +
8 +[[BMS_Main_3X_v3.6.0.bin>>FileManager.BMS_Main_3X_v3\.6\.0\.bin]]
9 +
10 +== Features ==
11 +
12 +* Unibat: refined algorithms and new parameters to meet requirements of version 8.5 of the logic (protocol v6.1)
13 +
14 +== Improvements ==
15 +
16 +* new flag enabling fast current measurements (see the "Signals - Current sensor" section)
17 +* new parameters to ignore the specified errors when setting the critical error (see the "Protections - Critical error" section)
18 +* displaying HV calibration values for the service account (see the "Service - Calibration" section)
19 +* Unibat: structuring parameters into subgroups: "General parameters", "Battery parameters", "Diagnostic parameters", "Power limiting parameters", "Battery version" (see the "External equipment - Unibat vehicle" section)
20 +

22 +
23 +[[BMS_Main_3X_v3.5.0.bin>>FileManager.BMS_Main_3X_v3\.5\.0\.bin]]
24 +
25 +== Features ==
26 +
27 +* support for sending battery state and events via MQTT protocol via Wi-Fi or cellular network (see the "Service - MQTT" section)
28 +
29 +== Improvements ==
30 +
31 +* support for secure (TLS) connections in BMS GSM v1 and v2 drivers
32 +
33 +== Fixes ==
34 +
35 +* synchronization of the precharge procedure with the charge/discharge algorithms, so that precharge is stopped if charging and discharging are prohibited
36 +
37 += v3.4.0 =
38 +
39 +[[BMS_Main_3X_v3.4.0.bin>>FileManager.BMS_Main_3X_v3\.4\.0\.bin]]
40 +
41 +== Features ==
42 +
43 +* new protection checking that the voltage of joined battery modules is equal to the voltage before contactors (the "High voltage 1" value). If this is not the case, the error "Battery voltage mismatch" is generated (see the "Protections - Battery voltage" section)
44 +
45 +== Improvements ==
46 +
47 +* new CLI command "find-log" which finds a log file containing a specified timestamp
48 +* ability to acknowledge battery module errors via CLI (see the "Service - Errors journal" section) and Modbus protocol
49 +
50 +== Fixes ==
51 +
52 +* resolving the issue of rebooting the device if formatting the SD card is activated
53 +
54 += v3.3.0 =
55 +
56 +[[BMS_Main_3X_v3.3.0.bin>>FileManager.BMS_Main_3X_v3\.3\.0\.bin]]
57 +
58 +== Features ==
59 +
60 +* ability to calibrate high voltage measuring means, available starting with the service account (see the "Service - Calibration" section)
61 +
62 +== Improvements ==
63 +
64 +* new type of temperature sensors: NTC 10k B25/50=3380K (see the "Signals - Temperature sensors" section)
65 +
66 +
67 += v3.2.5 =
68 +
69 +[[BMS_Main_3X_v3.2.5.bin>>FileManager.BMS_Main_3X_v3\.2\.5\.bin]]
70 +
71 +== Improvements ==
72 +
73 +* dynamic calculation of data transfer schedule for optimal communication with a large number of battery modules
74 +* ability to complete device initialization after the set timeout has expired and the minimum number of modules has been detected (see the "Control - Initialization" section)
75 +* 30 second delay when remounting SD card after detecting mount error
76 +* saving the number of joined modules in log files
77 +* Unibat: new flag disabling insulation measurement
78 +* Unibat: calculation of the battery current depending on the connection variant of current sensors
79 +* Unibat: preventing HVILS changes if the battery is in power-down state
80 +
81 +== Fixes ==
82 +
83 +* resolving the problem of ignoring the parameter that selects the connection variant of current sensors
84 +* Unibat: corrections in message identifiers HVESSS1, HVESSD2, HVESSD3, HVESSD8, storing battery module data
85 +* Unibat: corrections in HVESSCFG message priority
