Diagnostic service for electric vehicle charging state confirmation
A recently granted patent (Publication Number: US11890962B1) discloses a computer-implemented method for managing the charging state of an electric vehicle's battery. The method involves receiving and processing vehicle bus messages to identify the initiation of charging, running a diagnostic service to confirm the battery's charging state, and transmitting relevant data to a management server. Additionally, the method includes monitoring the battery's state of charge, logging data, and responding to charging cancellation events by disabling the diagnostic service.
Furthermore, the patent describes a system that implements the method, utilizing a computer-readable storage medium and processors to manage the charging state of the electric vehicle's battery. The system can identify charging initiation, confirm the battery's state, transmit data to a management server, and monitor the battery's state of charge. It also includes features such as disabling the diagnostic service based on elapsed time without relevant messages and storing data in a communication protocol format like OBD-II or J1939. The system is designed to efficiently manage and monitor the charging process of electric vehicles, enhancing overall battery performance and maintenance.
