The invention discloses a block chain PBFT consensus optimization method suitable for charging pile management, and the method comprises the steps: initializing a block chain network, and setting a time interval for initiating PBFT consensus; after the block chain network receives the broadcast containing the charging pile use request information, adding one integral to the nodes reaching the consensus in the block chain, and reducing one integral to the nodes not reaching the consensus; using a verifiable random function to select consensus nodes from the nodes whose integrals are greater than an integral threshold, and selecting the node with the highest integral as a main node based on the consensus nodes; the main node initiates a consensus request to the whole block chain network regularly and actively according to a preset time interval, and when the main node collects 2f + 1 confirmation messages, the whole block chain network reaches a consensus; and after the consensus is reached, a new block contain
