Embodiment Construction

[0026] The embodiments of the present invention solve the technical problems of low power supply efficiency and short power supply time in the related art by providing a refrigerated container and a hybrid power supply system thereof.

[0027] The technical solutions provided by the embodiments of the present invention are to solve the above-mentioned technical problems, and the general idea is as follows:

[0028] The fuel-fired power supply group and the high-voltage battery power supply group are controlled by the control module, so that the fuel-fired power generation power supply group and the high-voltage battery power supply group can alternately cycle power supply for the refrigerating unit of the refrigerated container, so that the fuel-fired power generation and power supply can be used when the high-voltage battery power supply group is working The group suspends work, reducing fuel consumption. Only when the power of the high-voltage battery power supply group is in...

Abstract

According to the refrigerated container and the hybrid power supply system thereof provided by the embodiment of the invention, the fuel oil power generation and supply group and the high-voltage storage battery power supply group can be controlled through the control module to alternately and circularly supply power to the refrigerating unit, so that the refrigerating unit can be supplied with power by the fuel oil power generation and supply group and the high-voltage storage battery power supply group when the high-voltage storage battery power supply group works; only when the electric quantity of the high-voltage storage battery power supply group is insufficient, the fuel power generation power supply group is controlled to charge the high-voltage storage battery power supply group, so that on one hand, the continuous power supply capability of the high-voltage storage battery power supply group is ensured; and on the other hand, the electric energy generated by the fuel oil power generation and supply unit is fully utilized, the working efficiency of the fuel oil power generation and supply unit is improved, the power supply efficiency of the hybrid power supply system is improved, and the power supply time is prolonged.

Description

technical field [0001] The invention relates to the technical field of power supply, in particular to a refrigerated container and a hybrid power supply system thereof. Background technique [0002] With the improvement of people's living standards, people's demand for perishable food is getting higher and higher. According to incomplete statistics, there are about 600,000 TEU (Transmission extension unit) refrigerated containers in use worldwide. Variety, timeliness" direction of development. Due to the large transportation span and long transportation distance of perishable food, and most perishable food needs to be imported, it is necessary to use refrigerated containers as the carrier for transportation. [0003] At present, the power supply methods of railway cold chain transportation equipment are self-powered and centralized power supply. Most of the energy used for cooling is fuel oil. The power generation and power supply unit is driven by burning fuel oil to gene...
