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 68 - 69 69 = v1.68.0 = 70 70 71 71 [[BMS_Main_2.1_v1.68.0.srec>>FileManager.BMS_Main_2\.1_v1\.68\.0\.srec]]
