Description
The EVAL-L9963E-NDS is a hardware tool for L9963E for Li-ION battery management application. The board is intended to be used as a single node in a distributed BMS. EVAL-L9963E-NDS is needed when the total number of battery cells to be managed exceeds 14. The number of nodes to be stacked depends on total battery voltage, additional nodes can be added via additional EVAL-L9963E-NDS. A maximum of 31 total nodes beyond the base node EVAL-L9963E-MCU can be stacked. It has to be used in conjunction with EVAL-L9963E-MCU as second stage or stacked with additional EVAL-L9963E-NDS.
Features
• Single node L9963E board for distributed multi-cell BMS
• To be used with EVAL-L9963E-MCU or EVAL-L9963E as second stage or
stacked with additional EVAL-L9963E-NDS
• Measures from 4 to 14 cells in series, with 0 us desynchronization delay
between samples. Supports also busbar connection without altering cell results
• Coulomb counter supporting pack overcurrent detection in both ignition on and
off states
• Fully synchronized current and voltage samples
• 16-bit voltage measurement
• Communication between nodes through a 2.66 Mbps isolated serial
communication with regenerative buffer, supporting dual access ring
• Transformer based isolation
• Up to 4 analog inputs for NTC sensing, plus PCB temperature sensing
• Hot-plug protection circuit
