The invention discloses an electric vehicle Internet of vehicles system based on a block chain technology and a working method thereof. The system comprises clients which are used for carrying out input, communication and data display on information of charge stations, charge facilities, customers and vehicles; data collection terminals which are used for collecting charge real-time data of the charge facilities, and collecting real-time data of vehicle operation; and a cloud which is composed of a multi-node block chain module network, wherein each block chain node comprises a block chain data authentication module, a block chain data storage module and a block chain application management module. The real-time data collected by the data collection terminals is sent to block chain modulesof the cloud. The system and the method have the advantages that rapid access and interconnection of hard resources such as the charge facilities, electric vehicles and parking spaces can be realized, and the access and service sharing of soft resources such as content service providers and vehicle service providers can be realized, thereby forming a multi-win situation.
