BATTERY MANAGEMENT SYSTEMS (BMS)
MG Master HV — BMS for high-voltage battery systems up to 900 V
Country: Netherlands · Model: Master HV
Master HV manages MG high-voltage battery strings from 48 to 900 V DC and switches them with a contactor of up to 500 A. A separate master is installed for each series string, so system capacity is increased by parallel strings.

Description
The unit performs protection, control, monitoring and energy metering of the string. The range includes Master HV 300, 500 and 500 G2, as well as a 19-inch rack version of 750 V and 160 A. The rack model works in the range of 300–750 V DC, the others up to 900 V DC. The electronics are powered from 18–32 V DC, and data is exchanged over a CAN Bus with M12 connectors. The 500 G2 version has an IP65 case for engine rooms and machinery, while the 19-inch IP30 version is installed only in a closed rack. The unit has DNV-GL and Lloyd's approvals and complies with IEC-EN 62619 (ES-TRIN); the customs code according to the manufacturer is 8537109199.
How to choose
The choice between versions depends on the string voltage, current and installation place. For systems of up to 750 V in a 19-inch cabinet the 160 A rack model is convenient; for vessels and mobile machinery the 500 A G2 with IP65. If the battery is low-voltage, 12–96 V, and currents reach 1000 A, a Master LV is needed.
