Abstract

The present disclosure provides a cascade communication device and method and a battery management system. The cascade communication device includes: a first interface for received data in uplink mode and transmitting data in downlink mode, and receiving a first clock signal; a second interface for transmitting data in uplink mode and received data in downlink mode, and transmitting a second clock signal; an edge detection module for detecting an edge of the first clock signal; a clock generation module for generating the second clock signal according to the edge of the first clock signal; a data processing module for reconstructing a received data according to the first clock signal and the second clock signal to generate a transmission data. The cascade communication system includes a serial synchronous interface based on the public protocol, the reliability of multi-stage data transmission is improved, and a greater number of node devices is supported.
