The embodiment of the invention provides a heating control method and device, an oil pump and a heat exchange system. The method comprises the steps that in the cold state, heating current is injected into an oil pump motor, wherein when the oil pump motor is not started, the torque generated by the heating current is zero; after the oil pump motor is started, the heating power of the heating current is larger than that of the energy-saving current, and the energy-saving current is the current capable of enabling the first motor to reach the target operation condition when the oil temperature is larger than the preset temperature threshold value. 本申请实施例提供了一种加热控制方法、装置、油泵及热交换系统，其中，方法包括：在冷态时，向油泵电机注入发热电流；其中，在油泵电机未启动时，发热电流能产生的转矩为零；在油泵电机启动后，发热电流的发热功率大于节能电流的发热功率，节能电流为在油温大于预设温度阈值时能第一电机达到目标运行工况的电流。
