Abstract
The present application provides a chip communication circuit, method and apparatus based on automatic clock synchronization. The method includes: determining clock synchronization information of a first battery management chip in response to a received control instruction; replacing a chip selection enable signal in the control instruction with a clock synchronization signal carrying the clock synchronization information of the first battery management chip to obtain a new control instruction; and transmitting the new control instruction to other battery management chips, so that the other battery management chips perform automatic clock synchronization based on the clock synchronization information carried in the new control instruction; where the other battery management chips are battery management chips among the multiple battery management chips except for the first battery management chip, and a daisy chain with a sinusoidal sawtooth waveform is used for isolated communication between different battery management chips.
