The embodiment of the invention provides a communication system and method based on a daisy chain, belongs to the technical field of communication, and is applied to battery module detection communication, the system comprises a plurality of differential transceivers in communication connection with a main control chip, the differential transceivers and battery units of the battery modules are arranged in a one-to-one correspondence mode, and the differential transceivers are connected with the main control chip in a one-to-one correspondence mode. Each differential transceiver establishes communication based on the improved daisy chain; wherein the improved daisy chain is constructed based on direct current coupling; each differential transceiver is integrated with an independent AFE chip and is used for executing battery parameter acquisition of the corresponding battery unit; and each differential transceiver is used for transmitting the battery parameters of the corresponding battery unit back to the main control chip through differential signals. The scheme of the invention has remarkable technical effects in the aspects of improving communication efficiency, reducing cost and enhancing system integration.
