Electric vehicle charging pile is suitable for DC system energy storage

The charging circuit's topological layout is situated within the casing. The power supply is sourced from either the DC junction of the DC distribution network or the total transmission line of the photovoltaic system. The arrangement of the charging circuit comprises the following: it is located on the total transmission line, with a switch to control the input power. The output end of the switch undergoes continuous measuring and assembly. The power measuring assembly goes through the DC/DC converter continuous capacitor energy storage assembly, and the power output end of the capacitor energy storage assembly feeds into the DC/AC converter output charging power to the output filter circuit. The output filter circuit's output end is connected to the continuous optimum current output circuit. Both the measuring assembly and capacitor energy storage assembly undergo continuous human-computer interaction control.

The electric vehicle charging system utilizes an electric vehicle charging pile to gather user identity information and charging requirements from a corresponding application. This data is then transmitted to an upper computer through a communication unit, allowing the system to receive and process charging instructions. With the help of a charging unit, the EV charging pile is able to carry out charging procedures promptly and efficiently.

Whether or not the connection between the EV charging pile and the upper computer remains stable, the system is able to continue carrying out necessary charging actions. In situations where the web page remains functional, the upper computer can oversee and regulate the charging process for each EV charging pile. This system ensures quick and reliable charging for electric vehicles, making it a highly practical option for consumers.

The assembly of electric vehicle charging pile includes various components such as the terminal control CPU module, wireless communication module, power metering module, LED status display module, radio frequency identification card reader module, power module, and light guidance module. The main control CPU module of the terminal is responsible for coordinating and supervising the other modules. The wireless communication module establishes a continuous connection between the main control CPU module of the EV charging pile terminal and the upper computer system of the regulating master station, enabling seamless wireless communication.

To ensure the proper functioning and cooling of the upper computer in the regulating master station, a cooling assembly in the form of a cabinet with refrigerant is employed. This refrigerant helps in maintaining a suitable temperature for the upper computer. One innovative feature of the cooling assembly is the incorporation of parent and child buckles. The parent buckle houses embedded sub-buckles, while the sub-buckles consist of a base and embedded discussion. This design eliminates common issues such as limited cooling capacity, low thermal management efficiency, and inadequate reliability in ensuring the accuracy of the host computer's operations in the master station. Furthermore, it promotes secure and precise connections between the child buckle and the mother buckle, preventing any accidental disconnections.
