The invention discloses a double-battery linkage device for an electric power-assisted bicycle. The double-battery linkage device comprises a main battery pack, an auxiliary battery pack, a main battery pack control module, an auxiliary battery pack control module, a detection module, a main controller and a kickstand piezoelectric power generation assembly. The main battery pack is connected witha load to provide power for an electric power-assisted bicycle; a main charging relay is arranged between the main battery pack and the load; the main charging relay controls conduction between the main battery pack and the load, the auxiliary battery pack is electrically connected with the main battery pack and the load, a mutual charging circuit and an auxiliary charging relay are arranged between the auxiliary battery pack and the main battery pack and between the auxiliary battery pack and the load respectively, and the kickstand piezoelectric power generation assembly is electrically connected with the auxiliary battery pack. The invention belongs to the technical field of electric power-assisted bicycle power sources, and particularly provides a double-battery linkage device for anelectric power-assisted bicycle. The double-battery linkage device is high in power supply efficiency and high in reliability and provides power for a standby battery pack of the electric power-assisted bicycle through self weight.
