The "External 1" output is directly controlled by the "Close External 1" command. 70 -* new "Precharge error" flag that is set when precharging cannot be completed 71 -* 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 72 -* 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) 73 - 74 -== Improvements == 75 - 76 -* ignoring the "Need acknowledge" flag when generating Modbus input register 0x2128 ("Error") 77 -* 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) 78 -* improving resistance calculation 79 - 80 -== Fixes == 81 - 82 -* resolving the issue where the "Need acknowledge" signal is not set if any of the device errors are not acknowledged in the error journal 83 -* using the calculated open circuit voltage to set/clear the "Ready to charge" and "Ready to discharge" signals 84 - 85 -= v1.68.0 = 86 - 87 -[[BMS_Main_2.1_v1.68.0.srec>>FileManager.BMS_Main_2\.1_v1\.68\.0\.srec]] 88 - 89 -== Features == 90 - 91 -- support for charge/discharge cycling using XD Discharger (see the sections "External equipment - Battery cycling" and "External equipment - XD Discharger (cycling)") 92 - 93 93 = v1.67.0 = 94 94 95 95 [[BMS_Main_2.1_v1.67.0.srec>>FileManager.BMS_Main_2\.1_v1\.67\.0\.srec]]
