The present disclosure provides a temperature control system based on magnetic refrigeration technology, and thermal management system and method for battery pack of electric vehicle. A heat dissipation box is connected with one side of an accommodation box through a pipeline and the other side is connected to form a loop. The heat dissipation box comprises a heat dissipation box body, a pluralityof heat dissipation fins are sequentially sleeved on the outer edge, and an electromagnetic body and a heating pipe are arranged on the inner surface. The accommodation box comprises an outer heat insulating box body and an inner microchannel partition box, the microchannel partition box includes a plurality of accommodation chambers separated by microchannel partitions, At that front and rear wall surface of the box body, a plurality of transverse and longitudinal connected pipelines are arrange inside the box body, A plurality of connecting branch pipes are arranged inside the microchannelseparator, The connecting branch pipe is communicated with the connecting pipe, and the temperature drop of the magnetic fluid coolant flowing out of the radiator box is caused by the magnetocaloric effect of the magnetic refrigerating material, so that the temperature of the magnetic fluid coolant entering the container box from the cold flow pipe can be effectively reduced, and the consistency of the internal temperature of the acted object can be maintained.
Description
technical field [0001] The present disclosure relates to a temperature control system based on magnetic refrigeration technology, a thermal management system and method for an electric vehicle battery pack. Background technique [0002] Driven by the energy crisis and environmental pollution problems, new energy technologies represented by power batteries have been developed rapidly and widely used. As the power source of many devices (such as electric vehicles), the battery pack is closely related to the overall performance of the device. [0003] However, in the actual application of the above-mentioned equipment using the battery pack as the power source, the battery cells are usually connected in series and parallel to form a battery pack to provide a suitable voltage and sufficient power. During the operation or charging of the equipment, the chemical reaction inside the battery and the internal resistance of the battery itself cause the battery cell to heat up and cau...
