  "textContent": "To prevent circulation of illicit products of batteries for electric vehicles. A 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 automobile 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 and allow the history information to be gathered together with the ID of the automobile by a maintenance device and a data server via an electronic control unit, and furthermore a maintenance service system is constructed.",
