Product Overview

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. EVAL-L9963E-NDS allows the user to manage up to 14 channels for cell voltage sensing, one channel for current sensing, and up to 4 analogue input for temperature sensing (plus an additional on-board NTC to sense PCB temperature). The board provides additional protection for hot plug. EVAL-L9963E-NDS is not intended to be used as a standalone evaluation board but with EVAL-L9963E-MCU.
  • 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 EVAL-L9963E-NDS
  • Measures from 4 to 14 cells in series, with 0 us desynchronization delay between samples
  • Coulomb counter supporting pack overcurrent detection in both ignition on and off states
  • Fully synchronized current and voltage samples
  • 16-bit voltage measurement
  • Transformer based isolation
  • Up to 4 analogue inputs for NTC sensing, plus PCB temperature sensing
  • Hot plug protection circuit
