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)

21
22 == Features ==
23
Admin 11.1 24 * new parameters allowing to set different delays for battery discharge mode to detect the overcurrent error (see the "Protections - Overcurrent protection" section)
Admin 10.1 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

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

80
81 == Features ==
82
83 * 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
84
85 == Improvements ==
86
87 * 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)
