Key features
- Accurate measurements: The system provides high accuracy and stability for precise data collection with a resolution of 1 millivolt.
- Wide voltage range: The system supports a voltage range of 0–20 V DC for individual units, with a maximum battery string voltage of 300 V DC per loop.
- Durable and safe: The BVM system complies with safety standards (CE, RoHS, EMC) and features protection against overvoltage, reverse voltage, and electrostatic discharge (ESD). It is intended for use in medium-voltage substations and industrial settings.
- Flexible connections: The included "dolphin clips" can be exchanged with other types of clamps and cables to suit different battery connection requirements.
- Modular design: One BVM unit is used for each cell or block in the battery bank being tested.
- Daisy-chain connection: The units are linked together, which provides an easy and expandable way to handle a large number of batteries. The BVM150 kit includes 16 units, but the system can be expanded to test up to 242 cells (2 loops of 121).
- Automated setup: The "Auto Discovery" feature automatically detects the number of batteries and assigns a sequential ID to each BVM unit for easy monitoring.
- Data collection: During a capacity test, the BVM units accurately measure and record the voltage of each individual cell. This data is logged and can be analyzed using software like TORKEL Win or PowerDB.
- Integration: The BVM system is designed to integrate seamlessly with Megger's TORKEL load units, but can also be used with other load banks with the aid of a PC.
