The invention discloses a charging device reservation method based on GPRS/3G/4G. wherein the charging device comprises a ground charger, a charger/charging bow monitoring and GPRS/3G/4G communicationmodule, a charging bow frame body and other devices or structures; the vehicle end device comprises a GPRS/3G/4G communication module, a charging reservation key switch and other devices or structures. The ground charger and the vehicle are connected to the vehicle operation platform and/or the charger management platform through GPRS/3G/4G. A special warning lamp or a display screen and other equipment are arranged at a fixed charging parking space on the ground; And when the vehicle needs to be charged in operation, the communication equipment at the vehicle end sends the charging reservation request to the vehicle operation platform and/or the charger management platform, and the vehicle operation platform and/or the charger management platform issue the reservation request to the charger equipment corresponding to the charging parking space. According to the method and the device, the utilization rate of the ground fixed charging parking space can be effectively improved, the riskthat the charging parking space is occupied for no reason is reduced, and particularly, the bus line operation efficiency is improved.
