Description

Technical Field

[0001] This invention relates to the field of electric vehicle charging system research and development design technology, and in particular to an integrated multi-interface charging system for electric vehicles and its working method. Background Technology

[0002] With the development of technology, the electric vehicle market is showing a diversified development trend. Light electric bicycles are popular due to their mobility and flexibility, and their multi-functional design meets the needs of different users. Electric vehicles play an important role in many fields, mainly including sightseeing passenger transport, security patrol, and cargo transportation. Electric vehicles are commonly used in parks, scenic spots, resorts, universities, hospitals, and other places as sightseeing passenger transport tools, as well as for security patrols in station squares and densely populated areas. In addition, they are also used for cargo transportation in factories, ports, and logistics warehouses. While electric vehicles bring convenience to people, another problem has gradually emerged: how to make charging more convenient for users. Currently, electric vehicles only have one charging port, which is generally a slow charging port. Fast charging can be selected when charging is urgently needed, but this method is more damaging to the battery. On the other hand, slow charging is too time-consuming. Some people replace the battery to achieve quick use, but this method often results in batteries that are too heavy and inconvenient to use, and there is also a risk of theft. Therefore, further improvements are needed. Summary of the Invention

[0003] This invention addresses the shortcomings of the prior art by providing an integrated multi-interface charging system for electric vehicles that is convenient to use, highly safe, and widely applicable, as well as its operating method.

[0004] The technical solution adopted by the present invention to solve the above problems is as follows:

[0005] This invention provides an integrated multi-interface charging system for electric vehicles.

[0006] The system includes a control unit, which is connected to at least one fast charging port for fast charging and at least one slow charging port for slow charging.

[0007] The fast charging interface and the slow charging interface are electrically connected to the power supply system.

[0008] The control unit is also electrically connected to a display device and an energy storage device.

[0009] Furthermore, the fast-charging interface is connected to the energy storage device via the first charging module.

[0010] The slow-charging interface is connected to the energy storage device through the second charging module.

[0011] Furthermore, the energy storage device is electrically connected to a power monitoring system and a power indication system, which are electrically connected to the display device for displaying the power and charging status of the energy storage device.

[0012] Furthermore, the fast charging interface and the slow charging interface are connected to the energy storage device via an emergency switch, which is used to control the disconnection or connection of the first charging module and the second charging module in an emergency.

[0013] Furthermore, the fast charging interface and the slow charging interface are connected to the energy storage device through a current conversion system.

[0014] The current conversion system is used to convert AC power from the power supply system into DC power to supply the energy storage device.

[0015] Furthermore, the control unit is also connected to a charging status monitoring module, which is used to detect the charging time and battery capacity of the battery.

[0016] Furthermore, the charging status monitoring module is electrically connected to the power monitoring system, and the charging status monitoring module includes a timing unit, an analysis unit, an automatic switch module, and an alert module.

[0017] The timing unit is used to receive information from the power monitoring system. If the energy storage device continues to be connected to the power supply system for a certain period of time after charging is completed, the timing unit will send the information to the analysis unit. After receiving and confirming the information, the analysis unit will send instructions to the automatic switch module and the reminder module to remind and disconnect the power to prevent overcharging and fire hazards.

[0018] Furthermore, the automatic switch module is connected to the energy storage device, and the timing unit is also used to receive information from the power monitoring system. When the power is insufficient after the energy storage device has been discharging for a certain period of time, the timing unit sends the information to the analysis unit. After receiving and confirming the information, the analysis unit sends an instruction to the reminder module to perform a reminder operation.

[0019] Furthermore, the control unit is also connected to a temperature control circuit, a selection module, and a high-strength lightning protection module.

[0020] The temperature control circuit is used to detect the temperature of the energy storage device.

[0021] The selection module is used to identify and select the fast charging interface or the slow charging interface during charging, and display the selection on the display device.

[0022] The high-strength lightning protection module is used to protect electric vehicles under extreme conditions.

[0023] A method for operating an integrated multi-interface charging system for electric vehicles includes the following steps:

[0024] S1: Select the charging interface. Depending on the needs of the usage environment, select either the fast charging interface for fast charging or the slow charging interface for slow charging to charge the electric vehicle.

[0025] S2: The charging mode is determined and selected by the selection module;

[0026] During charging, the fast charging interface or the slow charging interface is identified and selected, and the selection is displayed on the display device.

[0027] S3: The display device shows the energy level, charging mode, and charging status of the energy storage device;

[0028] S4: The charging status monitoring module monitors the charging status of the energy storage device;

[0029] If the energy storage device remains connected to the power supply system for a certain period of time after charging is completed, the timing unit will send information to the analysis unit. After receiving and confirming the information, the analysis unit will send instructions to the automatic switch module and the reminder module to remind and cut off the power, so as to prevent overcharging and fire hazards.

[0030] After the energy storage device discharges for a certain period of time, if the power is insufficient, the timing unit will send information to the analysis unit. After receiving and confirming the information, the analysis unit will send an instruction to the reminder module to perform a reminder operation.

[0031] S5: The temperature control circuit detects the temperature of the energy storage device.

[0032] The beneficial effects of this invention are as follows:

[0033] The integrated multi-interface charging system and its working method for electric vehicles provided by this invention have advantages such as ease of use, high safety, and wide applicability. This application greatly facilitates the user by simultaneously providing at least one fast charging interface and one slow charging interface on the electric vehicle. When the battery is low, it can be charged at any time via fast charging, or charged via a regular charging interface when not in a hurry. This application ensures both user convenience and improved safety. This application is applicable not only to electric vehicles, but also to motorcycles and tricycles. Therefore, this application has great economic and practical value. Attached Figure Description
