7 +
8 +[[BMS_Main_3X_v3.5.0.bin>>FileManager.BMS_Main_3X_v3\.5\.0\.bin]]
9 +
10 +== Features ==
11 +
12 +* support for sending battery state and events via MQTT protocol via Wi-Fi or cellular network (see the "Service - MQTT" section)
13 +
14 +== Improvements ==
15 +
16 +* support for secure (TLS) connections in BMS GSM v1 and v2 drivers
17 +
18 +== Fixes ==
19 +
20 +* synchronization of the precharge procedure with the charge/discharge algorithms, so that precharge is stopped if charging and discharging are prohibited
21 +
22 += v3.4.0 =
23 +
24 +[[BMS_Main_3X_v3.4.0.bin>>FileManager.BMS_Main_3X_v3\.4\.0\.bin]]
25 +
26 +== Features ==
27 +
28 +* 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)
29 +
30 +== Improvements ==
31 +
32 +* new CLI command "find-log" which finds a log file containing a specified timestamp
33 +* ability to acknowledge battery module errors via CLI (see the "Service - Errors journal" section) and Modbus protocol
34 +
35 +== Fixes ==
36 +
37 +* resolving the issue of rebooting the device if formatting the SD card is activated
38 +
39 += v3.3.0 =
40 +
41 +[[BMS_Main_3X_v3.3.0.bin>>FileManager.BMS_Main_3X_v3\.3\.0\.bin]]
42 +
43 +== Features ==
44 +
45 +* ability to calibrate high voltage measuring means, available starting with the service account (see the "Service - Calibration" section)
46 +
47 +== Improvements ==
48 +
49 +* new type of temperature sensors: NTC 10k B25/50=3380K (see the "Signals - Temperature sensors" section)
50 +
51 +
52 += v3.2.5 =
53 +
54 +[[BMS_Main_3X_v3.2.5.bin>>FileManager.BMS_Main_3X_v3\.2\.5\.bin]]
55 +
56 +== Improvements ==
57 +
58 +* dynamic calculation of data transfer schedule for optimal communication with a large number of battery modules
59 +* 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)
60 +* 30 second delay when remounting SD card after detecting mount error
61 +* saving the number of joined modules in log files
62 +* Unibat: new flag disabling insulation measurement
63 +* Unibat: calculation of the battery current depending on the connection variant of current sensors
64 +* Unibat: preventing HVILS changes if the battery is in power-down state
65 +
66 +== Fixes ==
67 +
68 +* resolving the problem of ignoring the parameter that selects the connection variant of current sensors
69 +* Unibat: corrections in message identifiers HVESSS1, HVESSD2, HVESSD3, HVESSD8, storing battery module data
70 +* Unibat: corrections in HVESSCFG message priority
71 +
72 += v3.2.4 =
73 +
74 +[[BMS_Main_3X_v3.2.4.bin>>FileManager.BMS_Main_3X_v3\.2\.4\.bin]]
75 +
76 +== Improvements ==
77 +
78 +* new flags that allow to interrupt (shorten) the module balancing stage if all battery modules are already joined (see the "Control - Charge", "Control - Discharge", "Control - Charge/Discharge" sections)
79 +* forwarding CLI and bootloader CAN messages from CAN1 interface to CAN2 interface and back, that allows the user to configure and update the firmware of internal devices such as BMS IMD or BMS Display
80 +* new parameter for setting the type of network to which the BMS GSM communication module connects (see the "Connectivity - Cellular" section)
81 +
82 +== Fixes ==
83 +
84 +* Unibat: resolving the problem of calculating the CRC of the HVESSS1 message
85 +* Unibat: resolving the problem of sending a message about battery disconnection even it is already disconnected
86 +
87 += v3.2.3 =
88 +
89 +[[BMS_Main_3X_v3.2.3.bin>>FileManager.BMS_Main_3X_v3\.2\.3\.bin]]
90 +
91 +== Improvements ==
92 +
93 +* forwarding CLI and bootloader CAN messages from CAN1 and CAN2 interfaces to CAN3 interface and back, that allows the user to configure and update the firmware of battery modules without direct connection to the modules
94 +* ability to acknowledge errors in the error journal via the Modbus protocol (holding registers 0x4100-0x4101)
95 +* ability to update the device serial number from the service account if the number is reset to the default value for some reason (see the "Service" section)
96 +* new flag that controls whether to use open circuit voltage or actual voltage when determining the voltage unbalance error (see the "Protections - Voltage unbalance (in any state)" section)
97 +* new regulator that maintains battery current limiting to ensure that actual module currents do not exceed their current limits (see the "Control - Charge", "Control - Discharge", "Control - Charge/Discharge" sections)
98 +* ability to select the battery module errors that cause the battery critical error (see the "Protections - Critical error" section)
99 +* Unibat: refined algorithms and new parameters to meet requirements of version 7 of the logic
100 +
101 +== Fixes ==
102 +
103 +* resolving the problem of saving discrete input signals of battery modules in log files
