The embodiment of the invention provides a power system and an electric automobile. The system comprises a portable power source, an automobile-mounted battery, a manager, an electronic quantity detection device and a single-chip microcomputer. The automobile-mounted battery is connected with a motor and supplies electric energy to the motor. The electronic quantity detection device is connected with the portable power source and the automobile-mounted battery so as to detect the residual electronic quantity of the portable power source and the automobile-mounted battery and send the residual electronic quantity to the single-chip microcomputer. The single-chip microcomputer is connected with the electronic quantity detection device so as to receive the residual electronic quantity obtained through detection of the electronic quantity detection device and judge whether the residual electronic quantity obtained through detection of the electronic quantity detection device is lower than a preset threshold value
