9 +
10 +== Improvements ==
11 +
12 +* new assignments "Low SOC" and "High charging current" for relays
13 +
14 +== Fixes ==
15 +
16 +* resolving the issue of ill-considered reduction of the battery SOC level when the cell voltage is close to the level corresponding to SOC=0% (due to the flow of a large discharge current leading to the high voltage drop on the cells)

20 +[[BMS_Main_2.1_v1.70.0.srec>>FileManager.BMS_Main_2\.1_v1\.70\.0\.srec]]
21 +
22 +== Features ==
23 +
24 +* new parameters allowing to set different delays for battery discharge mode to detect the overcurrent error (see the "Protections - Overcurrent protection" section)
25 +* new flag that sets whether the BMS should wait for confirmation messages from the Combilift truck to start charging or not (see the "External equipment - Combilift truck" section)
26 +
27 +== Fixes ==
28 +
29 +* optimization of the logging process, minimizing the time to open the next log file if the current one is full

34 +
35 +== Fixes ==
36 +
37 +* check the HYG and Combilift confirmation flags only if the truck offline error is not set
38 +* small internal fixes

41 +
42 +[[BMS_Main_2.1_v1.69.0.srec>>FileManager.BMS_Main_2\.1_v1\.69\.0\.srec]]
43 +
44 +== Features ==
45 +
46 +* new parameter for setting the condition for starting balancing: automatically (regardless of the command) or on the balancing request (see the "Cells - Cell balancing" section)
47 +* new option to start balancing if the cell voltage exceeds the "Voltage for forced balancing" value (see the "Cells - Cell balancing" section)
48 +* new assignment "Balancing request" for the discrete inputs (see the "Signals - Input signals" section)
49 +* new Max-Min algorithm for calculating the final battery SOC in the "Cells - SOC estimation" section
50 +* new algorithms "Automatic" and "On command" for the main contactor (see the "Cells - Main contactor" section)
51 +* new assignment "Close Main contactor" for the discrete inputs to close the main contactor by a command
52 +* new assignment "Close External 1" for the discrete inputs (see the "Signals - Input signals" section)
53 +* new assignment "External 1" for the discrete outputs and relays (see the "Signals - Output signals" section). The "External 1" output is directly controlled by the "Close External 1" command.
54 +* new "Precharge error" flag that is set when precharging cannot be completed
55 +* new flags in the "Protections - Undervoltage protection" and "Protections - Overvoltage protection" sections which allow using the calculated open circuit cell voltage instead of the actual voltage to detect the "Undervoltage" and "Overvoltage" errors, respectively
56 +* ability to check the "Ready to charge" and "Ready to discharge" signals to control the charging and discharging contactors (see the "Cells - Charging control" and "Cells - Discharging control" sections)
57 +
58 +== Improvements ==
59 +
60 +* ignoring the "Need acknowledge" flag when generating Modbus input register 0x2128 ("Error")
61 +* explicit flags to enable the use of the charging current limit for fast and/or normal charging when using the CCS Fast charge controller (see the "External equipment - CCS Fast charge controller" section)
62 +* improving resistance calculation
63 +
64 +== Fixes ==
65 +
66 +* resolving the issue where the "Need acknowledge" signal is not set if any of the device errors are not acknowledged in the error journal
67 +* using the calculated open circuit voltage to set/clear the "Ready to charge" and "Ready to discharge" signals
