Abstract: A power conversion system, an energy storage system and a power supply method are provided. The power conversion system includes a battery management system and an auxiliary power supply. A positive electrode of the auxiliary power supply is connected to a positive electrode of a battery rack. The auxiliary power supply is configured to obtain power from the battery rack, convert the power obtained from the battery rack, and supply the converted power to the battery management system and a load in the power conversion system. The battery management system is configured to sample a voltage of the battery rack and a current of the battery rack, and control charging and discharging of the battery rack based on the voltage and the current.

Abstract: Disclosed are a method and an apparatus for eliminating a glitch, and a state machine, which are used for improving the accuracy of data transmission. The method includes: acquiring a transmission instruction of to-be-transmitted data, the transmission instruction at least carry the data; when it is determined that a first slave state machine can transmit the data, transmitting the to-be-transmitted data to the first state according to the transmission instruction; transferring the data according to a preset transfer state; when it is determined that a clock cycle for transmitting the data reaches a preset clock cycle, transferring the to-be-transmitted data to a preset state; and when it is determined that a preset transmission time is reached, transmitting the data.
