6 += v2.8.1 =
7 +
8 +[[BMS_Main_3_v2.8.1.bin>>FileManager.BMS_Main_3_v2\.8\.1\.bin]]
9 +
10 +== Fixes ==
11 +
12 +* resolving the problem of incorrectly saving battery cell data
13 +* resolving the problem where the "HYG offline" error does not occur if the global HYG class is selected in the device settings
14 +
15 += v2.8.0 =
16 +
17 +[[BMS_Main_3_v2.8.0.bin>>FileManager.BMS_Main_3_v2\.8\.0\.bin]]
18 +
19 +== Features ==
20 +
21 +* new profile section with global battery status, which includes total charge and energy counters, total operating time, contactor switching count, etc. (see the "Profile" tab in the Unified monitor)
22 +* new total charge counters (plus and minus)
23 +* new SOH estimation algorithm that calculates SOH as a linear function of the total charge (minus) (see the "Control - SOH estimation" section)
24 +
25 +== Improvements ==
26 +
27 +* support for 32-bit BMS Logic serial numbers
28 +
29 +== Fixes ==
30 +
31 +* optimization of the logging process, minimizing the time to open the next log file if the current one is full
32 +* resolving the stability problem when the SD card is full
33 +
34 += v2.7.1 =
35 +
36 +[[BMS_Main_3_v2.7.1.bin>>FileManager.BMS_Main_3_v2\.7\.1\.bin]]
37 +
38 +== Improvements ==
39 +
40 +* turning on power switches with a delay of 1 second after reaching the supply voltage of 9V
41 +* ability to generate the "Logic count error" also during BMS initialization (scanning of BMS Logic devices); new parameters for setting delays before/after generating/clearing the error (see the "Protections - Logic count" section)
42 +* 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 RS-485-1 (Modbus) settings; LAN settings: IP mode, IP address, Netmask, Gateway address
43 +
44 +== Fixes ==
45 +
46 +* small fixes in dynamic current maps
47 +
48 += v2.7.0 =
49 +
50 +[[BMS_Main_3_v2.7.0.bin>>FileManager.BMS_Main_3_v2\.7\.0\.bin]]
51 +
52 +== Features ==
53 +
54 +* new algorithm for detecting loss of wire connection to battery cells
55 +* new protection for detecting battery cell imbalance (see the "Protections - Cell imbalance" section)
56 +* new "Main X offline" error indicating loss of connection with the BMS Main X device
57 +
58 +== Improvements ==
59 +
60 +* new flag enabling fast current measurements (see the "Signals - Current sensor" section)
61 +* new parameters that control setting/clearing the "Ready to charge" and "Ready to discharge" signals based on the charge and/or discharge current limits (see the "Control - Charging status" and "Control - Discharging status" sections)
62 +* new parameters to ignore the specified errors when setting the critical error (see the "Protections - Critical error" section)
63 +* displaying HV calibration values for the service account (see the "Service - Calibration" section)
