9
10 == Features ==
11
12 * new parameters allowing to set different delays for battery discharge mode to detect the overcurrent error (see the "Protections - Overcurrent protection" section)
13 * 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)
14
15 == Fixes ==
16
17 * optimization of the logging process, minimizing the time to open the next log file if the current one is full

22
23 == Fixes ==
24
25 * check the HYG and Combilift confirmation flags only if the truck offline error is not set
26 * small internal fixes

31
32 == Features ==
33
34 * 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)
35 * new option to start balancing if the cell voltage exceeds the "Voltage for forced balancing" value (see the "Cells - Cell balancing" section)
36 * new assignment "Balancing request" for the discrete inputs (see the "Signals - Input signals" section)
37 * new Max-Min algorithm for calculating the final battery SOC in the "Cells - SOC estimation" section
38 * new algorithms "Automatic" and "On command" for the main contactor (see the "Cells - Main contactor" section)
39 * new assignment "Close Main contactor" for the discrete inputs to close the main contactor by a command
40 * new assignment "Close External 1" for the discrete inputs (see the "Signals - Input signals" section)
41 * 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.
42 * new "Precharge error" flag that is set when precharging cannot be completed
43 * 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
44 * 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)
45
46 == Improvements ==
47
48 * ignoring the "Need acknowledge" flag when generating Modbus input register 0x2128 ("Error")
49 * 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)
50 * improving resistance calculation
51
52 == Fixes ==
53
54 * resolving the issue where the "Need acknowledge" signal is not set if any of the device errors are not acknowledged in the error journal
55 * using the calculated open circuit voltage to set/clear the "Ready to charge" and "Ready to discharge" signals

68
69 == Features ==
70
71 * new additional heater controller (see the "Protections - Heater (AUX) control" section), which generates the "Heater (AUX)" signal, which can be assigned to a discrete output or relay
72
73 == Improvements ==
74
75 * new balancing strategy that attempts to keep the temperature of BMS Logic devices below a set value by discharging cells with higher voltages first than others (see the "Cells - Cell balancing" section)
