A motor control apparatus and method. The apparatus receives a feedback signal by means of a sensor; on the basis of the feedback signal, the apparatus calculates an angle of the position of a motor; the apparatus obtains a correction angle on the basis of the feedback signal or an input instruction; the apparatus calculates a current command value on the basis of the correction angle and the angle; and the apparatus outputs the current command value to the motor.

An immersion cooling system includes a cooling tank and a filtration system. The cooling tank is configured to accommodate a liquid coolant and an electronic device immersed in the liquid coolant. The filtration system includes a pipeline, a pump, a filter and a cooling device. The pipeline is in fluid communication with the cooling tank. The pump is disposed in the pipeline and is configured to drive the liquid coolant to flow through the pipeline. The filter is disposed in the pipeline and is configured to filter the liquid coolant. The cooling device is connected to the pipeline and is configured to cool the liquid coolant. The pipeline has an inlet connected to the cooling tank. The cooling device is located between the pump and the inlet of the pipeline.

An energy storage cabinet includes a frame supporting multiple battery packs and a cooling device. The frame includes a support with a pipe and a partition dividing an internal fluid passage of the pipe into a first flow channel and a second flow channel. Each battery pack has a first vent and a second vent. The second vent of a first battery pack is in communication with the second flow channel. The first vent of a second battery pack is in communication with the first flow channel. The cooling device produces a cool air entering the first vent of the first battery pack and the first flow channel. As the cool air passes through the first battery pack, the cool air is heated and becomes a warm air, which is then discharged into the second flow channel through the second vent.
