Problems solved by technology

like figure 1 As shown, the usual solution is to install a high-power refrigeration system in the box. The existing refrigeration system and charging power supply are separated, and each system is controlled separately, which may cause local overheating of the power module, and is not conducive to energy saving and coordinated control.

Embodiment Construction

[0021] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0022] see figure 1 The schematic block diagram of the existing charging station is shown, which is composed of a refrigeration system and a charging station power module, both of which are powered independently by AC, and the charging station power module converts alternating current through AC / DC and DC / DC into direct current for charging electric vehicles; The refrigeration system converts alternating current to direct current to drive frequency conversion compressor and frequency conversion fan to meet the normal operation of the refrigeration system. The heat source power module and coolin...

Abstract

The invention discloses a charging station of an integrated refrigeration system and a control method thereof. The charging station comprises a refrigeration system, a power source conversion module used for converting an external power supply into direct current, a charging power source and a refrigerating system power source connected to the output end of the power source conversion module in parallel, and a control module that communicates with the power source conversion module, the refrigerating system power source and a detection device in the charging power source respectively and controls the refrigerating system and the charging power source to operate coordinately according to detection parameters. Compared with the prior art, the refrigerating system and the charging power source are integrally controlled, the temperature of the heating source end can be controlled, the problem of local overheating of the power supply module is solved, and the safety performance of the wholesystem is improved; the refrigeration system power source and the charging power source are integrally developed, so that system cost can be saved; working modes can be set according to using preferences and regions and seasons, efficiency and safety are both considered, and the application range can be wider.

Description

technical field [0001] The invention relates to a charging station, in particular to a charging station with an integrated refrigeration system and a control method thereof. Background technique [0002] In large-scale charging stations, container-type charging stations are usually used. The container-type charging station has the advantages of convenient movement and convenient modular splicing. It integrates a charging power supply, a cooling system and a monitoring module inside, and is connected to multiple charging guns for charging electric vehicles at the same time. Due to the integrated charging power supply, a large amount of heat will be generated in the box, and the cooling system is particularly important at this time. Such as figure 1 As shown, the usual solution is to install a high-power refrigeration system in the box. The existing refrigeration system and charging power supply are separated, and each system is controlled separately, which may cause local ...
