  • Patent number: 11420526
    Abstract: A processor included in a server acquires, by a weather information acquisition unit, weather information related to rainfall in a region where an external charging of a vehicle is performed. The processor also acquires flooding information indicative of prediction of flood damage to the region from a flooding information DB included in a storage device. If the vehicle is determined, based on the acquired weather information and flooding information, as likely to be inundated with water while the vehicle is stationary in the charging station, the processor transmits to the vehicle a stop instruction for stopping the external charging. The vehicle stops the external charging if the vehicle receives the stop instruction for stopping the external charging from the server.
