| 11 | |||
| 12 | * 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) | ||
| 13 | * new option to start balancing if the cell voltage exceeds the "Voltage for forced balancing" value (see the "Cells - Cell balancing" section) | ||
| 14 | * new assignment "Balancing request" for the discrete inputs (see the "Signals - Input signals" section) | ||
| 15 | * new Max-Min algorithm for calculating the final battery SOC in the "Cells - SOC estimation" section | ||
| 16 | * new algorithms "Automatic" and "On command" for the main contactor (see the "Cells - Main contactor" section) | ||
| 17 | * new assignment "Close Main contactor" for the discrete inputs to close the main contactor by a command | ||
| 18 | * new assignment "Close External 1" for the discrete inputs (see the "Signals - Input signals" section) | ||
| 19 | * 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. | ||
| 20 | * new "Precharge error" flag that is set when precharging cannot be completed | ||
| 21 | * 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 | ||
| 22 | * 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) | ||
| 23 | |||
| 24 | == Improvements == | ||
| 25 | |||
| 26 | * ignoring the "Need acknowledge" flag when generating Modbus input register 0x2128 ("Error") | ||
| 27 | * 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) | ||
| 28 | * improving resistance calculation | ||
| 29 | |||
| 30 | == Fixes == | ||
| 31 | |||
| 32 | * resolving the issue where the "Need acknowledge" signal is not set if any of the device errors are not acknowledged in the error journal | ||
| 33 | * using the calculated open circuit voltage to set/clear the "Ready to charge" and "Ready to discharge" signals | ||

| 47 | == Features == | ||
| 48 | |||
| 49 | * 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 | ||
| 50 | |||
| 51 | == Improvements == | ||
| 52 | |||
| 53 | * 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) | ||
