New energy automobile charging fault prompting method and device, electronic equipment and medium

The invention provides a new energy automobile charging fault prompting method and device, electronic equipment and a medium. The method comprises the following steps: monitoring an event in a charging process, and when the event is judged to be a charging fault event, encoding the charging fault event by using an encoding rule to obtain a charging fault event code; performing fault reason division on the charging fault event code by using the fault reason set to determine the fault reason set; according to the charging state, the fault reason set, the fault grade and the charging gun connection state of the battery management system, performing fault classification on the current charging fault to obtain a fault category enumeration value; and the fault category enumeration value is sent to a fault prompting system, so that the fault prompting system determines an operation prompt word, and the operation prompt word is sent to a cabin terminal and/or a mobile terminal for display. The charging failure reason
