BMS Main 2.1

Last modified by Admin on 2025/02/19 10:47

BMS Main 2.1 firmware update procedure is described here.

v1.69.1

BMS_Main_2.1_v1.69.1.srec 

Fixes

  • check the HYG and Combilift confirmation flags only if the truck offline error is not set
  • small internal fixes

v1.69.0

BMS_Main_2.1_v1.69.0.srec 

Features

  • new parameter for setting the condition for starting balancing: automatically (regardless of the command) or on the balancing request (see the "Cells - Cell balancing" section)
  • new option to start balancing if the cell voltage exceeds the "Voltage for forced balancing" value (see the "Cells - Cell balancing" section)
  • new assignment "Balancing request" for the discrete inputs (see the "Signals - Input signals" section)
  • new Max-Min algorithm for calculating the final battery SOC in the "Cells - SOC estimation" section
  • new algorithms "Automatic" and "On command" for the main contactor (see the "Cells - Main contactor" section)
  • new assignment "Close Main contactor" for the discrete inputs to close the main contactor by a command
  • new assignment "Close External 1" for the discrete inputs (see the "Signals - Input signals" section)
  • new assignment "External 1" for the discrete outputs and relays (see the "Signals - Output signals" section). The "External 1" output is directly controlled by the "Close External 1" command.
  • new "Precharge error" flag that is set when precharging cannot be completed
  • 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
  • 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)

Improvements

  • ignoring the "Need acknowledge" flag when generating Modbus input register 0x2128 ("Error")
  • 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)
  • improving resistance calculation

Fixes

  • resolving the issue where the "Need acknowledge" signal is not set if any of the device errors are not acknowledged in the error journal
  • using the calculated open circuit voltage to set/clear the "Ready to charge" and "Ready to discharge" signals

v1.68.0

BMS_Main_2.1_v1.68.0.srec 

Features

- support for charge/discharge cycling using XD Discharger (see the sections "External equipment - Battery cycling" and "External equipment - XD Discharger (cycling)")

v1.67.0

BMS_Main_2.1_v1.67.0.srec 

Features

  • new additional heater controller (see the "Protections - Heater (AUX) control" section), which generates the "Heater (AUX)" signal, which can be assigned to a discrete output or relay

Improvements

  • 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 "Cells - Cell balancing" section)

v1.66.1

BMS_Main_2.1_v1.66.1.srec 

Improvements

  • closing all TCP connections over Ethernet if the interface link is down

v1.66.0

BMS_Main_2.1_v1.66.0.srec 

Features

  • support for the insulation monitoring device BMS IMD (see the section "External equipment - BMS IMD device")

Improvements

  • new parameters for switching off the Discharging (AUX) relay when the cell voltage is too low (see the "Cells - Discharging (AUX) control" section)
