Disclosed is a blockchain-based electricity charge settlement method and system for an energy storage station. A trusted terminal directly collects two-way electricity quantity data of an energy storage station, and distributes the two-way electricity quantity data to a blockchain; and a consensus node of a power-consuming enterprise and a consensus node of an energy storage station investment operator in the blockchain perform consensus calculation on the two-way electricity quantity data, and write the two-way electricity quantity data into the blockchain after reaching a consensus. The two-way electricity quantity data is accurate and cannot be tampered with, ensuring authenticity of the two-way electricity quantity data. A smart settlement contract is executed, an electricity charge settlement result is generated automatically to ensure authenticity of the electricity charge settlement result, and the electricity charge settlement result is written into the blockchain to prevent the electricity charge settlement result from being tampered with.
