| 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 | ||

| 60 | |||
| 61 | == Features == | ||
| 62 | |||
| 63 | - support for charge/discharge cycling using XD Discharger (see the sections "External equipment - Battery cycling" and "External equipment - XD Discharger (cycling)") | ||

| 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) | ||
