[0003] At present, there are more and more types of new energy vehicles on the market, and the charging pile control system is not perfect enough to suit the charging of all new energy vehicles. It is also unable to adaptively adjust the charging power and detect the status of the battery, and cannot fully capture the power grid information to obtain the optimal charging strategy. Summary of the invention

[0004] The present invention aims to address the deficiencies of the above-mentioned prior art and provides a highly practical and adaptive multi-scenario intelligent charging method for new energy vehicles.

[0009] The intelligent charging control module also controls the energy recovery and storage submodules to ensure the continuity and stability of the charging process.

[0010] Furthermore, the intelligent charging control module obtains battery information through communication, and collects power, current, voltage, etc. of the charging facilities and real-time electricity price data of the power grid. The intelligent charging control module dynamically calculates the optimal charging current, voltage and charging time to realize the charging process.

[0011] Furthermore, the adaptive charging interface adjusts its own physical structure and electrical parameters in a short time through a built-in intelligent recognition chip and an electric adjustment mechanism to achieve matching with the vehicle charging interface;

[0012] At the same time, the adaptive charging interface has good electrical isolation and overvoltage and overcurrent protection functions.

[0013] Furthermore, the wireless communication unit performs real-time data transmission with the management platform of the charging pile operator, the smart meter of the power grid and the remote service center of the vehicle manufacturer, and communicates with the management platform of the charging pile operator to obtain the real-time status, available power and queue information of the charging pile to help users plan charging trips in advance.

[0015] Furthermore, the energy recovery and storage submodule is composed of a supercapacitor and an energy conversion circuit. During the charging process, when the power output of the charging device is greater than the actual charging demand of the vehicle battery, the energy conversion circuit will store the excess electrical energy in the supercapacitor;

[0029] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings required for use in the embodiments or the description of the prior art will be briefly introduced below. Obviously, the drawings described below are some embodiments of the present invention. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying creative work.

[0030] Attached Figure 1 It is a flow chart of an adaptive multi-scenario intelligent charging method for new energy vehicles. DETAILED DESCRIPTION

[0031] In order to enable those skilled in the art to better understand the solution of the present invention, the present invention is further described in detail below in conjunction with specific implementation methods. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] A best embodiment is given below:

[0033] like Figure 1 As shown, an adaptive multi-scenario new energy vehicle intelligent charging method in this embodiment includes an intelligent charging control module, which communicates in real time with the vehicle battery management system BMS and external charging facilities through a wireless communication unit;

[0034] The intelligent charging control module controls the adaptive charging interface, which automatically identifies different types of new energy vehicle charging interface standards;

[0035] The intelligent charging control module also controls the energy recovery and storage submodules to ensure the continuity and smoothness of the charging process.

[0036] The intelligent charging control module integrates a high-performance microprocessor and complex algorithm programs. Through real-time communication with the vehicle battery management system (BMS) and external charging facilities, it obtains information such as the current battery power, voltage, temperature, and health status, and collects parameters such as power, current, and voltage of the charging facilities as well as real-time electricity price data from the power grid. Based on this information, the intelligent charging control module uses a preset optimization algorithm to dynamically calculate the optimal charging current, voltage, and charging time to achieve an efficient, economical, and safe charging process.

[0037] For example, when it is detected that the battery temperature is too high, the control module will automatically reduce the charging current to avoid damage to the battery due to overheating; charging tasks will be prioritized during periods of lower electricity prices.

[0038] The adaptive charging interface can automatically identify different types of new energy vehicle charging interface standards, such as national standards, European standards, American standards, etc. Through the built-in intelligent recognition chip and electric adjustment mechanism, the charging interface can adjust its own physical structure and electrical parameters in a short time to achieve fast and accurate matching with the vehicle charging interface.

[0039] At the same time, the interface has good electrical isolation and overvoltage and overcurrent protection functions, ensuring that electrical failures will not cause harm to vehicles and personnel during the charging process.

[0040] In order to realize the information exchange between the charging system and the outside world, the wireless communication unit supports multiple communication protocols, such as 4G, 5G, Wi-Fi, etc., and can transmit real-time data with the management platform of the charging pile operator, the smart meter of the power grid, and the remote service center of the vehicle manufacturer. By communicating with the management platform of the charging pile operator, the charging system can obtain the real-time status, available power, and queuing information of the charging pile, etc., to help users plan their charging trips in advance. Communication with the smart meter of the power grid enables the system to obtain electricity price information in real time in order to formulate the optimal charging strategy.

[0041] In addition, the wireless communication unit can also upload the vehicle's charging data and battery status information to the vehicle manufacturer's remote service center, providing data support for the vehicle's after-sales service and battery health management.

[0042] The energy recovery and storage subsystem consists of a supercapacitor and an energy conversion circuit. During the charging process, when the power output of the charging device is greater than the actual charging demand of the vehicle battery, the energy conversion circuit will store the excess electric energy in the supercapacitor; and when the vehicle battery needs a larger instantaneous charging power or the power grid is briefly interrupted, the supercapacitor can quickly release the stored energy to ensure the continuity and stability of the charging process. This can not only reduce energy waste, but also improve the adaptability of the charging system to complex power grid environments.

[0043] By implementing the above detailed process, the present invention can improve charging efficiency, reduce charging costs, extend battery life, enhance charging versatility, and improve energy utilization efficiency.

[0044] Based on the above method, an adaptive multi-scenario new energy vehicle intelligent charging system in this embodiment includes an intelligent charging control module, which communicates in real time with the vehicle battery management system BMS and external charging facilities through a wireless communication unit;

[0047] Among them, the intelligent charging control module obtains battery information through communication, and collects the power, current, voltage, etc. of the charging facilities and the real-time electricity price data of the power grid. The intelligent charging control module dynamically calculates the optimal charging current, voltage and charging time to realize the charging process.

[0048] The adaptive charging interface uses a built-in intelligent recognition chip and electric adjustment mechanism to adjust its physical structure and electrical parameters in a short time to match the vehicle charging interface;

[0049] At the same time, the adaptive charging interface has good electrical isolation and overvoltage and overcurrent protection functions.

[0050] The wireless communication unit transmits real-time data with the management platform of the charging pile operator, the smart meter of the power grid and the remote service center of the vehicle manufacturer. It communicates with the management platform of the charging pile operator to obtain the real-time status, available power and queue information of the charging pile to help users plan their charging trips in advance. The communication with the smart meter of the power grid enables the system to obtain electricity price information in real time in order to formulate the optimal charging strategy.

[0051] The wireless communication unit can also upload the vehicle's charging data and battery status information to the vehicle manufacturer's remote service center, providing data support for the vehicle's after-sales service and battery health management.

[0052] The energy recovery and storage submodule consists of a supercapacitor and an energy conversion circuit. During the charging process, when the power output of the charging device is greater than the actual charging demand of the vehicle battery, the energy conversion circuit will store the excess electrical energy in the supercapacitor.

[0053] When the vehicle battery requires a large instantaneous charging power or there is a brief interruption in the power supply of the power grid, the supercapacitor quickly releases the stored energy to ensure the continuity and smoothness of the charging process.
