If this is not the case, the "T-sensor count error" is generated (see the "Protections - Temperature sensor count" section) 29 -* new internal protection that checks for overheating of MOSFETs and generates the "MOSFET error" (see the "Protections - MOSFET" section) 30 -* new internal protection that checks for power failures in the device and generates the "Power fault" error 31 -* new error "Main X offline" which is generated when the connection with BMS Main X is lost 32 -* detection of loss of wire connection to battery cells 33 - 34 -== Improvements == 35 - 36 -* new parameters that control setting/clearing the "Ready to charge" and "Ready to discharge" signals based on the charge and/or discharge current limits (see the "Control - Charging status" and "Control - Discharging status" sections) 37 -* new parameters to ignore the specified errors when setting the critical error (see the "Protections - Critical error" section) 38 -* expansion of the list of parameters that are reset to default values when the device is powered on while holding the button on the board. The following parameters are affected: all CAN settings; all RS-485 (Modbus) settings; LAN settings: IP mode, IP address, Netmask, Gateway address 39 -* improved stability of the BMS Wi-Fi V2 driver 40 -* improved stability of the BMS GSM driver 41 - 42 -== Fixes == 43 - 44 -* synchronization of the precharge procedure with the charge/discharge algorithms, so that precharge is stopped if charging and discharging are prohibited 45 -* resolving the problem of communication with the DC EV supply equipment 46 - 47 -= v1.7.0 = 48 - 49 -[[BMS_Mini_v1.7.0.srec>>FileManager.BMS_Mini_v1\.7\.0\.srec]] 50 - 51 -== Features == 52 - 53 -* support for DC EV supply equipment according to IEC 61851-25 standard 54 - 55 -== Improvements == 56 - 57 -* new flags for generating the "Ready to charge" and "Ready to discharge" signals using the actual cell voltage instead of the calculated open circuit voltage (see the "Control - Charging status" and "Control - Discharging status" sections) 58 -* 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 59 -* new parameter setting a delay before measuring battery current during precharge (see the "Control - Precharge" section) 60 -* 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) 61 -* 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) 62 -* 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) 63 -* 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) 64 -* 30 second delay when remounting SD card after detecting mount error 65 -* new types of temperature sensors: NTC 100k B25/50=4250K and NTC 10k B25/50=3380K (see the "Signals - Temperature sensors" section) 66 - 67 -= v1.6.2 = 68 - 69 -[[BMS_Mini_v1.6.2.srec>>FileManager.BMS_Mini_v1\.6\.2\.srec]] 70 - 71 -== Improvements == 72 - 73 -* new parameter for setting the type of network to which the BMS GSM communication module connects (see the "Connectivity - Cellular" section) 74 -* ignoring the "Need acknowledge" flag when generating Modbus input register 0x2128 ("Error") 75 - 76 -== Fixes == 77 - 78 -* 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) 79 - 80 80 = v1.6.1 = 81 81 82 82 [[BMS_Mini_v1.6.1.srec>>FileManager.BMS_Mini_v1\.6\.1\.srec]]
