Description

Technical Field

[0001] The present application relates to the technical field of new energy charging equipment, and in particular to a mobile charging pile. Background Art

[0002] New energy vehicle charging piles are key infrastructure for providing power supply for electric vehicles (including pure electric vehicles, plug-in hybrid vehicles, etc.). They are usually installed in public places or private residential areas to facilitate electric vehicle users to charge.

[0003] There is a charging pile in the prior art, which includes: a charging pile body, a charging module, a control system, a communication module, a metering module, and a safety protection device. Specifically, the charging pile body is the external structure of the charging pile, which is usually made of steel, aluminum alloy and other materials. It protects the various components inside the charging pile and prevents damage from the external environment. The charging module is the core part of the charging pile, including components such as a charger and a controller. The charger is responsible for converting the AC power of the power grid into the DC power required by the electric vehicle, while the controller is responsible for controlling the working state of the charger and various parameters in the charging process, such as charging current, voltage and charging time. The control system is responsible for managing and controlling the charging process of the charging pile, including starting, stopping, and charging mode selection. It communicates with the battery management system of the electric vehicle to obtain the charging state and demand of the battery, and then adjusts the output of the power conversion device based on this information to charge the battery with the most suitable current and voltage. The communication module realizes communication between the charging pile and the electric vehicle, the power grid and the remote monitoring center. It transmits information such as charging state, power, faults, etc. to ensure that the charging pile can work normally and keep in touch with the outside world. The communication mode can be power line communication (PLC) or wireless communication, such as Wi-Fi, Bluetooth, etc. The metering module is used to measure the energy consumption during the charging process and realize the calculation of charging costs. It usually includes an energy meter, a billing unit and related data processing modules to ensure the accuracy and fairness of the charging costs. Safety protection devices are an important part of the charging pile, including overcurrent protection, overvoltage protection, undervoltage protection, overtemperature protection, etc. These protection measures can cut off the power supply in time when an abnormal situation occurs to prevent equipment damage or personal injury. In addition, the charging pile also needs to take safety protection measures such as lightning protection and electromagnetic interference protection to ensure its stable operation. In addition to the above main components, the new energy vehicle charging pile also includes charging interfaces, control panels, etc. The charging interface is a physical interface connecting the charging pile and the electric vehicle, which is used to transmit power and control signals. The control panel is the interface for users to interact with the charging pile, providing operation buttons, display screens, etc. Users can select charging mode, start charging, set parameters, etc. through the control panel.

[0042] The implementation principle of a mobile charging pile in the embodiment of the present application is: The user determines the demand through the numerical control board 15, and the inlet and outlet 14 is opened to unlock the blocking rod 62. The user pulls out the power sub-pile 7 through the push rod. Due to the obstruction of the limit baffle 54, the second slide rail is pulled out until the power sub-pile 7 is outside the energy storage bin 1. The chassis 74 is controlled to move downward through the height adjustment component 8 until the universal wheel 75 touches the ground smoothly. Unlock the limit baffle 54 and pull out the power sub-pile 7 for use. The second slide rail is reset, and the empty dispatching seat 5 is sent to the appropriate second translation component 4 through the first translation component 3, and the position is recorded, and the lifting seat 2 is on standby. If a new user takes it, it is moved to the sub-cavity 112 at a suitable height, and the new power sub-pile 7 is transported to the inlet and outlet 14 through the second translation component 4, and the above process is repeated. If the user returns the power delivery pile 7 after charging, the lifting seat 2 is moved to the vacant dispatching seat 5, and the second translation assembly 4 is ordered to send it to the first translation assembly 3, and the above process is reversed to complete the return of the power delivery pile 7.

[0043] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
