The invention relates to a communication method and system of a battery management system, an automobile and a storage medium. The battery management system comprises a battery module, a master control board and M slave control boards, the battery module comprises M battery packs, each slave control board is connected with one battery pack and is configured to detect state parameters of the battery packs, M is an integer greater than 2, and M is an integer greater than 1. The communication method comprises a step of forming a target communication link of the battery management system according to a preset mode, and the target communication link is formed according to the following mode: determining a connection wire harness layout of the master control board and the M slave control boards according to a short wire harness principle, determining a mapping relation between the coded information of the slave control board and the physical position of the battery pack; and the master control board and the M slave control boards communicate according to the target communication link. According to the scheme provided by the invention, the anti-interference capability of daisy chain communication can be improved while the cost is reduced.
