The invention discloses a quantum key distribution system for safety communication of an electric vehicle intelligent charging network. The quantum key distribution is realized on the basis of a hierarchy KDC (Key Distribution Centre) mode. The distribution of the quantum key distribution system is performed by a key distribution unit. The key distribution unit comprises a key management module (1) and a key management module (2) of a charging station. The key management module (1) is positioned in an operation management center. Communication and transmission of data and commands are performed between the key management module (1) and the key management module (2) reciprocally via classic channels. Keys are provided for the key management module (2) by the key management module (1) via quantum channels. According to the quantum key distribution system for safety communication of the electric vehicle intelligent charging network, disclosed by the invention, unconditional safety communication of the data is realized, and stability and safety of the network operation are guaranteed.
