Abstract
An electric vehicle information system prevents circulation of non-authentic batteries and battery components for electric vehicles. An electric vehicle data processing system is employed that performs, on an electric vehicle battery module having a plurality of battery cells installed therein, authentication of individual battery cells and the battery module itself in a hierarchical manner using a microcomputer. An electric vehicle is configured so as to cause the microcomputer of the data processing system to accumulate voltage history and charge history of the batteries in a nonvolatile storage circuit. The history information and the electric vehicle ID can be gathered by a maintenance device and a data server via an electronic control unit of the electric vehicle. A maintenance service system may thus be provided.
