The invention relates to a control method of an electric water heater and the electric water heater, and relates to the technical field of electric water heaters. The method comprises the following steps: acquiring a first initial water outlet temperature and a first end water outlet temperature of a large-amount water consumption period; if the first ending water temperature is smaller than or equal to the hot water amount judgment temperature threshold value and the first starting water outlet temperature is larger than or equal to the target heating temperature, the target heating temperature is increased according to a first temperature adjusting rule; if the first ending water temperature is larger than the hot water amount judgment temperature threshold value, and the water temperature, detected in real time, of the middle of the inner container is larger than or equal to the water temperature threshold value of the inner container, the target heating temperature is lowered according to a second tempera
