The signal can be cleared in the "Service - Errors journal" section 16 -* new parameter for setting the condition for starting balancing: automatically (regardless of the command) or on the balancing request (see the "Control - Cell balancing" section) 17 -* new option to start balancing if the cell voltage exceeds the "Voltage for forced balancing" value (see the "Control - Cell balancing" section) 18 -* new Max-Min algorithm for calculating the final battery SOC in the "Control - SOC estimation" section 19 -* new flags in the "Protections - Undervoltage" and "Protections - Overvoltage" sections which allow using the calculated open circuit cell voltage instead of the actual voltage to detect the "Undervoltage" and "Overvoltage" errors, respectively 20 -* ability to check the "Ready to charge" and "Ready to discharge" signals to control the charging and discharging contactors (see the "Control - Charge" and "Control - Discharge" sections) 21 -* improved control of the precharging contactor, which can precharge capacitive load using multiple attempts and detect high power dissipated in the precharge resistor (see the "Control - Precharge" section) 22 -* ability to select errors that the device saves in the errors journal (see the "Service - Errors journal" section) 23 - 24 24 == Improvements == 25 25 26 -* ability to configure and monitor the device via the CAN1 (ext) bus 27 -* placing the device input signals to the "Battery" section and adding raw discrete inputs to the "Signals" section 28 - 29 -== Fixes == 30 - 31 -* using the calculated open circuit voltage to set/clear the "Ready to charge" and "Ready to discharge" signals 32 - 33 -= v2.1.1 = 34 - 35 -[[BMS_Main_3_v2.1.1.bin>>FileManager.BMS_Main_3_v2\.1\.1\.bin]] 36 - 37 -== Improvements == 38 - 39 39 * 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 "Control - Cell balancing" section) 40 40 41 41 == Fixes == ... ... @@ -43,20 +43,4 @@ 43 43 * resolving the possible problem of saving device parameters 44 44 * resolving the problem of writing the device's working time to a non-volatile memory very often 45 45 46 -= v2.1.0 = 47 - 48 -[[BMS_Main_3_v2.1.0.bin>>FileManager.BMS_Main_3_v2\.1\.0\.bin]] 49 - 50 -== Features == 51 - 52 -* new algorithms in the Charging/Discharging controller that allow to control the Charging/Discharging contactor independently from the Charging and Discharging signals (see the "Control - Charge/Discharge" section). The new "Independent" algorithms are preferred in the battery systems with one contactor. 53 -* selection of errors that cause reset of contactor control signals (see the "Control - Main contactor", "Control - Charge", "Control - Discharge", "Control - Charge/Discharge", "Control - Discharge (AUX)", "Control - Heater", "Control - Cooler", "Protections - General error", "Control - Charging status", "Control - Discharging status" sections) 54 -* new "Current limit error" which is set if the battery current exceeds the charging or discharging current limits (see the "Protections - Charge current limit" and "Protections - Discharge current limit" sections) 55 -* new parameter to select the method of calculating the battery voltage: sum the cell voltages or use the measured voltage before contactors (see the "Control - Common settings" section) 56 -* clearing the Discharging (AUX) signal if the cell voltage is too low (see the "Control - Discharge (AUX)" section) 57 -* new assignment "Close External 1" for the discrete inputs (see the "Signals - Input discrete signals - Assignments" section) 58 -* new assignment "External 1" for the discrete outputs and power switches (see the "Signals - Output discrete signals - Assignments" and "Signals - Power switches - Assignments" sections).
