[0003] However, most of the power supply systems are integrated inside the container or single-section train, so that the cargo transportation can only be direct, and a single refrigerated container cannot be unpacked in the middle. If the single-section train is unpacked separately, the reliability of refrigeration will be affected.

Embodiment 1
[0044] Embodiments of the present invention provide a hybrid power supply system, such as figure 1 shown, including:
[0045] Housing 101, the housing 101 is provided with a suspension structure, the suspension structure is used to be installed on the corner fittings of the refrigerated container, so that the housing 101 is suspended on the outside of the refrigerated container 102, and the refrigerated container 102 is used in railway transportation or ocean transportation .
[0046] A diesel generator power supply unit 103 , a high-voltage lithium battery power supply box 104 , a first converter 105 and a control module 106 are located in the casing 101 .
[0047] Wherein, the diesel generator power supply unit 103 and the high-voltage lithium battery power supply box 104 are respectively connected to the refrigeration unit 1022 in the refrigerated container; the first converter 105 is connected before the diesel generator power supply unit 103 and the high-voltage lithium ...
Embodiment 2
[0083] Based on the same inventive concept, the embodiment of the present invention also provides a refrigerated transportation equipment, which is applied in railway transportation or ocean transportation, such as Image 6 shown, including:
[0084] A refrigerated container 601, the refrigerated container 601 is provided with a refrigeration unit;
[0085] As in the first embodiment, the hybrid power supply system 602 is hung on the end of the refrigerated container 601 for powering the refrigerating unit.
[0086] Wherein, in addition to the refrigeration unit, the refrigerator 601 is also provided with a refrigeration controller. The hybrid power supply system 602 is as described in Embodiment 1, and will not be described in detail here.

Abstract
The invention relates to the technical field of power supply equipment, in particular to a hybrid power supply system and refrigerated transport device.The system comprises a shell, a suspension structure is arranged on the shell, and the suspension structure is used for being installed on a corner fitting of a refrigerated container; the diesel power generation and supply unit, the high-voltage lithium battery power supply box, the first converter and the control module are arranged in the shell, the diesel power generation and supply unit and the high-voltage lithium battery power supply box are both connected with the refrigerating unit in the refrigerated container, and the first converter is connected between the diesel power generation and supply unit and the high-voltage lithium battery power supply box. The first converter is provided with a first interface, and the high-voltage lithium battery power supply box is charged from an external alternating current power supply through the first interface; the control module is used for controlling the diesel power generation and supply unit and the high-voltage lithium battery power supply box to alternately and circularly supply power to the refrigerating unit, so that the system is independent of the refrigerated container, two power supply modes are adopted in the system to alternately and circularly supply power to the refrigerating unit, and the transportation reliability of the refrigerating unit is improved.
Description
technical field [0001] The invention relates to the technical field of power supply equipment, in particular to a hybrid power supply system and refrigerated transportation equipment. Background technique [0002] The existing cold chain transportation includes not only land transportation, but also sea transportation. Among them, the ones with large spans need to be transported in ocean-going refrigerated containers. The power supply mode of the cold chain transportation equipment of the railway is self-power supply and centralized power supply. Most of its refrigeration uses diesel oil to drive the generator set to generate electricity, supply power to the refrigeration unit, and ensure the quality of cold chain goods. [0003] However, most of the power supply systems are integrated in containers or single-section trains, so that the goods can only be transported directly, and a single refrigerated container cannot be unpacked in the middle. If the single-section train i...
