The embodiment of the invention discloses an oil temperature control method, a controller, a power assembly and an electric automobile, the oil temperature control method is applied to the controller of the electric automobile comprising an oil cooling loop, the oil cooling loop flows through a motor and an inverter, and the method comprises the following steps that the oil temperature of a detection point is determined; the detection point is a designated position in the oil cooling loop; when the oil temperature is lower than a first target temperature, triggering one or more of the following operations: bypassing an oil-water heat exchanger, reducing water flow and increasing oil pump power; and when the oil temperature is higher than a second target temperature, triggering to execute one or more of the following operations: closing a bypass oil-water heat exchanger, increasing the water flow rate and reducing the oil pump power. By adopting the technical scheme provided by the embodiment of the invention, the oil temperature in the oil cooling loop can be controlled within the target temperature range.
