The invention discloses a method and a device for updating position information of a charging facility and a navigation chip. The method comprises: determining the type of a vehicle according to the existing charging facility covered by the vehicle in an electronic map and the driving trajectory of a gas station, wherein the type of the vehicle comprises a charging vehicle or a fuel vehicle; screening the charging vehicle according to the type of the vehicle, and recognizing the charging facility unrecorded in the electronic map according to the driving trajectory of the charging vehicle. Thecharging facility unrecorded in the electronic map is recognized through big data mining and can be added to the electronic map, and the navigation chip can update the electronic map of the charging station/charging pile and push the electronic map to a client in real time, so that the timeliness of map update is increased, an effective trend can be given for internet of vehicles, smart transportation and smart cities, the cost of map update can be reduced and the needs of rapid urban development in the future are met.
