} Addressable on initialization
High-speed and robust daisy chain provides a smart
alternative to CAN solutions. Fast data acquisition and
communication to the pack controller can be achieved in
only 3.0 ms for the pack controller to acquire conversions
from 96 cells. Also, determination of individual cell
impedances in one shot is synchronized for cell voltages
and current measurements within 114 μs.
