If this is not the case, the error "Battery voltage mismatch" is generated (see the "Protections - Battery voltage" section) 46 -* new protection checking that the number of cell temperature sensors is equal to the specified value. If this is not the case, the "T-sensor count error" is generated (see the "Protections - Temperature sensor count" section) 47 - 48 -== Improvements == 49 - 50 -* new parameters that configure delays before and after the "Logic offline" error is generated (see the "Protections - Logic offline" section) 51 -* new CLI command "find-log" which finds a log file containing a specified timestamp 52 - 53 -== Fixes == 54 - 55 -* resolving the issue of rebooting the device if formatting the SD card is activated 56 - 57 -= v2.4.0 = 58 - 59 -[[BMS_Main_3_v2.4.0.bin>>FileManager.BMS_Main_3_v2\.4\.0\.bin]] 60 - 61 -== Features == 62 - 63 -* ability to communicate with BMS Logic devices via CLI (used in service-scripts, for example, to update BMS Logic firmware) 64 -* ability to calibrate high voltage measuring means, available starting with the service account (see the "Service - Calibration" section) 65 - 66 -== Improvements == 67 - 68 -* new type of temperature sensors: NTC 10k B25/50=3380K (see the "Signals - Temperature sensors" section) 69 - 70 -= v2.3.0 = 71 - 72 -[[BMS_Main_3_v2.3.0.bin>>FileManager.BMS_Main_3_v2\.3\.0\.bin]] 73 - 74 -== Improvements == 75 - 76 -* new parameter for setting the type of temperature sensors 1 and 2 connected to the device (sensors connected to BMS Logic devices and to BMS Main 3 device may differ; see the "Signals - Temperature sensors" section) 77 -* new flags that force only positive and negative currents to be used to determine open circuit voltages to control the "Ready to charge" and "Ready to discharge" signals respectively 78 -* new parameter setting a delay before measuring battery current during precharge (see the "Control - Precharge" section) 79 -* new flag to keep the precharging contactor closed until the precharging process is finished (in this case the "Precharge error" will not occur except for the one caused by high power; see the "Control - Precharge" section) 80 -* new flag to prevent the "HYG offline" error from occurring if the "Charger connected" signal is set (see the "External equipment - Trucks and Vehicles - HYG Class I-III truck" section) 81 -* new flag that controls whether to wait for confirmation from the HYG truck or not, to allow the battery to be charged (see the "External equipment - Trucks and Vehicles - HYG Class I-III truck" section) 82 -* new flag that controls whether to wait for confirmation from the Combilift truck or not, to allow the battery to be charged (see the "External equipment - Trucks and Vehicles - Combilift truck" section) 83 -* 30 second delay when remounting SD card after detecting mount error 84 -* new counter of retry attempts showing the communication problems with BMS Logic devices (see the "Battery" section) 85 - 86 -== Fixes == 87 - 88 -* increased number of retries when sending commands to BMS Logic devices, which reduces the number of false offline event detections 89 - 90 -= v2.2.3 = 91 - 92 -[[BMS_Main_3_v2.2.3.bin>>FileManager.BMS_Main_3_v2\.2\.3\.bin]] 93 - 94 -== Improvements == 95 - 96 -* new parameter for setting the type of network to which the BMS GSM communication module connects (see the "Connectivity - Cellular" section) 97 - 98 -== Fixes == 99 - 100 -* resolving the issue of ill-considered reduction of the battery SOC level when the cell voltage is close to the level corresponding to SOC=0% (due to the flow of a large discharge current leading to the high voltage drop on the cells) 101 - 102 102 = v2.2.2 = 103 103 104 104 [[BMS_Main_3_v2.2.2.bin>>FileManager.BMS_Main_3_v2\.2\.2\.bin]]
