According to an embodiment of the present invention, there is provided a low voltage compensation system for a micro electric vehicle including: a motor configured to drive a micro electric vehicle; a motor control unit configured to control the motor and supply power received from a main battery to the motor; a main battery configured to supply the power to the motor control unit; and a sub battery for compensating for a voltage of the main battery. According to the present invention, it is possible to prevent an output reduction due to a low voltage of the main battery by compensating for a dropped voltage of the main battery using the sub battery when the voltage of the main battery is dropped below a reference value by adding the sub battery in addition to the main battery, thereby efficiently and stably operating the micro electric vehicle.
