Active Balance chipset for use in large format Lithium-ion batteries that provides monitoring, balancing, and communications. With precise and robust active balancing, the Active Balance BMS is capable of bidirection power transfer at each cell. Each EM1401EVM can manage 6 to 14 cells (60V max) for Li-ion battery applications. The EM1401EVM modules can be stacked up to 1300V. The system provides fast cell balancing, diagnostics, and module to controller communication. Independent protection circuitry is also provided.
Features:
• Active Bi-Directional Cell Balancing
• Multi-Cell Charge/Discharge Capability
• Isolated Communications (5kV)
• Flexible Architecture for 6 to 14 cells
• CAN Bus Interface
• High Accuracy Cell Voltage Measurement
