Master BMS - High Voltage
48 Vdc up to 900 Vdc
High Voltage Certification
System Redundancy
The Master HV is the safety and control unit for high voltage battery systems. This high voltage BMS is suitable in the range of 48 Vdc up to 900 Vdc. Each battery string requires a Master BMS. To increase the system capacity, connect multiple strings in parallel. As a result your system voltage and capacity are fully scalable. This means: flexible in design and system integration made easier. Besides the safety and control functions, the Master HV monitors and tracks all relevant parameters to provide insight into the battery status and energy consumption. The compact design makes it ideal for use in applications with limited space.
All essential components for a safe and reliable battery system are integrated in this compact designed device.
- Integrated pre-charge circuit
- Safety contactors in positive and negative power paths
- High Voltage Interlock Loop (HVIL)
- Internal event logging
- CAN-Bus communication
- Tracking State-Of-Health and State-Of-Charge
- Monitoring of all battery parameters




Protection & Control
The main function of the Master HV is protecting all connected battery modules. This high voltage BMS collects all battery data and constantly monitors essential parameters. The Master HV includes two built-in safety contactors, one in the positive and one in the negative power path. The safety contactors disconnect the batteries directly from the chargers and loads when needed.
The Master HV includes many safety features as a standard, to ensure a safe and reliable battery installation:
- Double Safety Contactor
- High Voltage Interlock Loop
- Integrated Pre-Charge Circuit
