7 +
8 +[[BMS_Main_3_v2.8.0.bin>>FileManager.BMS_Main_3_v2\.8\.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 switching count, etc. (see the "Profile" tab in the Unified monitor)
13 +* new total charge counters (plus and minus)
14 +* new SOH estimation algorithm that calculates SOH as a linear function of the total charge (minus) (see the "Control - SOH estimation" section)
15 +
16 +== Improvements ==
17 +
18 +* support for 32-bit BMS Logic serial numbers
19 +
20 +== Fixes ==
21 +
22 +* optimization of the logging process, minimizing the time to open the next log file if the current one is full
23 +* resolving the stability problem when the SD card is full
24 +

26 +
27 +[[BMS_Main_3_v2.7.1.bin>>FileManager.BMS_Main_3_v2\.7\.1\.bin]]
28 +
29 +== Improvements ==
30 +
31 +* turning on power switches with a delay of 1 second after reaching the supply voltage of 9V
32 +* 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)
33 +* 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
34 +
35 +== Fixes ==
36 +
37 +* small fixes in dynamic current maps

39 += v2.7.0 =
40 +
41 +[[BMS_Main_3_v2.7.0.bin>>FileManager.BMS_Main_3_v2\.7\.0\.bin]]
42 +
43 +== Features ==
44 +
45 +* new algorithm for detecting loss of wire connection to battery cells
46 +* new protection for detecting battery cell imbalance (see the "Protections - Cell imbalance" section)
47 +* new "Main X offline" error indicating loss of connection with the BMS Main X device
48 +
49 +== Improvements ==
50 +
51 +* new flag enabling fast current measurements (see the "Signals - Current sensor" section)
52 +* 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)
53 +* new parameters to ignore the specified errors when setting the critical error (see the "Protections - Critical error" section)
54 +* displaying HV calibration values for the service account (see the "Service - Calibration" section)
55 +
56 += v2.6.0 =
57 +

59 +
60 +== Features ==
61 +
62 +* support for sending battery state and events via MQTT protocol via Wi-Fi or cellular network (see the "Service - MQTT" section)
63 +
64 +== Improvements ==
65 +
66 +* support for secure (TLS) connections in BMS GSM v1 and v2 drivers
67 +
68 +== Fixes ==
69 +
70 +* synchronization of the precharge procedure with the charge/discharge algorithms, so that precharge is stopped if charging and discharging are prohibited
