17 +
18 +== Features ==
19 +
20 +* new flag that forces the "Ready to discharge" signal to clear when the "Low SOC" signal is generated (see the "Control - Discharging status" section)
21 +* new input signal "Close External 2" which generates the new internal signal "External 2" which can be assigned to a discrete output or a power switch (see the "Signals - Input discrete signals - Assignments", "Signals - Output discrete signals - Assignments", and "Signals - Power switches - Assignments" sections)
22 +* ability to configure the generation of "External 1" and "External 2" signals based on other internal signals as an alternative to the "Close External 1" and "Close External 2" commands (see the "Signals - External 1-2 signals" section)
23 +
24 +== Improvements ==
25 +
26 +* new flags for generating the "Ready to charge" and "Ready to discharge" signals using the actual cell voltage instead of the calculated open circuit voltage (see the "Control - Charging status" and "Control - Discharging status" sections)
27 +* new flag the forces the device to wait for the "Charge request" and "Discharge request" signals to clear before reconnecting power contactors if the connection to the BMS Main X device is temporarily lost (see the "External equipment - BMS - Main X" section)
28 +* new CAN bus speed is not applied until the device is rebooted
29 +* logging the following new parameters: "Keyrun", "ChargeOn"
30 +
31 +== Fixes ==
32 +
33 +* resolving the problem of charge, discharge, and charge/discharge contactors closing when the "Precharge request" signal is set
34 +* resolving the problem of completing the initialization process before the power switch voltage stabilizes
35 +* resolving the problem of resetting the SOC of some cells to zero when starting the device

40 +
41 +== Fixes ==
42 +
43 +* resolving the problem of incorrectly saving battery cell data
44 +* resolving the problem where the "HYG offline" error does not occur if the global HYG class is selected in the device settings

49 +
50 +== Features ==
51 +
52 +* 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)
53 +* new total charge counters (plus and minus)
54 +* new SOH estimation algorithm that calculates SOH as a linear function of the total charge (minus) (see the "Control - SOH estimation" section)
55 +
56 +== Improvements ==
57 +
58 +* support for 32-bit BMS Logic serial numbers
59 +
60 +== Fixes ==
61 +
62 +* optimization of the logging process, minimizing the time to open the next log file if the current one is full
63 +* resolving the stability problem when the SD card is full
64 +
65 += v2.7.1 =
66 +
67 +[[BMS_Main_3_v2.7.1.bin>>FileManager.BMS_Main_3_v2\.7\.1\.bin]]
68 +
69 +== Improvements ==
70 +
71 +* turning on power switches with a delay of 1 second after reaching the supply voltage of 9V
72 +* 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)
73 +* 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
74 +
75 +== Fixes ==

83 +== Features ==
84 +
85 +* new algorithm for detecting loss of wire connection to battery cells
86 +* new protection for detecting battery cell imbalance (see the "Protections - Cell imbalance" section)
87 +* new "Main X offline" error indicating loss of connection with the BMS Main X device
88 +
89 +== Improvements ==
90 +
91 +* new flag enabling fast current measurements (see the "Signals - Current sensor" section)
92 +* 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)
93 +* new parameters to ignore the specified errors when setting the critical error (see the "Protections - Critical error" section)
94 +* displaying HV calibration values for the service account (see the "Service - Calibration" section)
