9 +
10 +== Improvements ==
11 +
12 +* dynamic calculation of data transfer schedule for optimal communication with a large number of battery modules
13 +* 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)
14 +* 30 second delay when remounting SD card after detecting mount error
15 +* saving the number of joined modules in log files
16 +* Unibat: new flag disabling insulation measurement
17 +* Unibat: calculation of the battery current depending on the connection variant of current sensors
18 +* Unibat: preventing HVILS changes if the battery is in power-down state
19 +
20 +== Fixes ==
21 +
22 +* resolving the problem of ignoring the parameter that selects the connection variant of current sensors
23 +* Unibat: corrections in message identifiers HVESSS1, HVESSD2, HVESSD3, HVESSD8, storing battery module data
24 +* Unibat: corrections in HVESSCFG message priority

29 +
30 +== Improvements ==
31 +
32 +* 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)
33 +* 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
34 +* new parameter for setting the type of network to which the BMS GSM communication module connects (see the "Connectivity - Cellular" section)
35 +
36 +== Fixes ==
37 +
38 +* Unibat: resolving the problem of calculating the CRC of the HVESSS1 message
39 +* Unibat: resolving the problem of sending a message about battery disconnection even it is already disconnected

42 +
43 +[[BMS_Main_3X_v3.2.3.bin>>FileManager.BMS_Main_3X_v3\.2\.3\.bin]]
44 +
45 +== Improvements ==
46 +
47 +* 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
48 +* ability to acknowledge errors in the error journal via the Modbus protocol (holding registers 0x4100-0x4101)
49 +* 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)
50 +* 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)
51 +* 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)
52 +* ability to select the battery module errors that cause the battery critical error (see the "Protections - Critical error" section)
53 +* Unibat: refined algorithms and new parameters to meet requirements of version 7 of the logic
54 +
55 +== Fixes ==
56 +
57 +* resolving the problem of saving discrete input signals of battery modules in log files
