MG Energy Systems Master HV Series - Next Generation LiIon Battery Solutions

800V 500A High-Voltage battery management control unit for battery systems 144V - 800V, With CAN-Bus communication

  • Compact design
  • Redundant Battery Management System
  • Easy installation
  • Integrated pre-charging
  • Compliant with the highest safety standards
  • Internal event logging
 

Protecting, monitoring and controlling a battery system is very important to create a safe, reliable and easy-to-use system. The MG Master HV is the safety and control unit of the battery system. It protects the connected battery modules against over-charging, over-discharging, over-temperature, under-temperature and controls the balancing of the battery cells. Besides a safety function, the Master HV monitors and tracks other important parameters to give insight in the battery status and energy consumption. The compact design makes it ideal for use in applications with limited space.

Power Connectors


Power connectors enable the Master HV to easily connect a series of batteries. The Amphenol PowerLok connectors are robust and have an integrated HVIL (High Voltage Interlock Loop) to monitor the connection. The low contact resistance allows for current up to 500 A continuously.

Monitoring and Control

Critical parameters are monitored by the Master LV such as cell voltages and temperatures of each connected battery module. A set of limits is determined providing boundaries. Several boundaries are set for each of the monitored parameters. First a control boundary which controls chargers or loads. Second a warning limit and third a critical fail which opens the safety contactors interrupting the power path from the batteries to loads and chargers. A well integrated system never opens its safety contactors during normal operation.         

 Diagnostic tool software

Battery system diagnostics are important during commissioning, system testing, service, maintenance and trouble shooting. The diagnostic tools provide all the detailed information about the battery system. Main values, like voltage, current and State-Of-Charge, can be viewed and logged to a file. Moreover, detailed battery information can be shown such as cell voltages, all temperature sensor, firmware version etc. Besides this information also history values and stored events can be read from the Master. To create more flexibility, settings can be configured, for example CAN-Bus protocol selection or adding a function to a dedicated output.
