The invention relates to an efficient range extending device for a new energy electric vehicle, which is used for charging a storage battery and comprises a shell, a variable gear is arranged in the shell, a transmission shaft is arranged in the variable gear in a penetrating manner, and a transmission gear sleeves the periphery of one end, extending out of the shell, of the transmission shaft and is used for being in transmission connection with an output shaft of a motor; the gear ratio of the change gear to the transmission gear is greater than or equal to 5: 1; a plurality of power generation gears are further arranged in the shell and are externally meshed with the speed change gear, and the gear number ratio of the speed change gear to the power generation gears is larger than or equal to 5: 1; a plurality of direct-current generators are further arranged on the outer side of the shell, and rotating shafts of the direct-current generators are fixedly connected with the power generation gears in a one-to-one correspondence mode. The output ends of the direct-current generators are electrically connected with the input end of the power distribution box, and the output end of the power distribution box is electrically connected with the charging end of the storage battery. The self-generating capacity is greatly improved, and the endurance mileage of the electric automobile can be increased.
