The invention belongs to the field of electric water heaters, and discloses an electric water heater and a supercharging control method thereof. The electric water heater comprises a booster water pump, a flow sensor and a controller, the booster water pump is arranged on a water inlet pipe of the electric water heater, the flow sensor is arranged on the water inlet pipe, and the controller is connected with the booster water pump and the flow sensor. According to the pressurization starting instruction, the controller obtains a first flow value, detected by a flow sensor, of a water inlet pipe; if the first flow value is smaller than the first preset flow threshold value, the controller controls the motor to stop running; if the first flow value is greater than or equal to a first preset flow threshold value and less than a second preset flow threshold value, the controller accumulates the duration; and if the duration is greater than a preset duration threshold value, the controller controls the motor to op
