Description

Technical Field

[0001] This invention relates to the field of novel charging technology, and more specifically, to an electric vehicle charging method and apparatus, storage medium, and processor. Background Technology

[0002] Traditional wireless charging involves installing a wireless transmitting coil on the ground and a wireless receiving coil on the vehicle body (usually the chassis). Traditional wireless charging solutions require significant modifications to the electric vehicle itself and necessitate close collaboration with automakers.

[0003] In the current plan, such as Figure 1 The wireless charging diagram shown illustrates that since electric vehicle battery charging requires the BMS to submit charging demands (such as charging voltage, charging current, and charging power) to the rectifier module 2, the operating voltage and current at the rectifier module need to be frequently adjusted. Adjusting the voltage and current at the rectifier module can cause changes in the operating characteristics of the high-frequency inverter module 1. However, a real-time closed-loop feedback cannot be established between the high-frequency inverter module and the rectifier module (even with high-speed wireless communication, real-time closed-loop feedback cannot be achieved). Therefore, the demand adjustment at the electric vehicle 3 cannot be met.

[0004] There is currently no effective solution to the above problems. Summary of the Invention

[0005] This invention provides an electric vehicle charging method, apparatus, storage medium, and processor to at least address the technical problem that existing electric vehicle charging methods cannot meet the changing charging demands of electric vehicles.

[0008] Optionally, the above-mentioned method of transmitting the charging energy to the target vehicle based on the charging demand includes: determining power supply information based on the charging demand; adjusting the charging energy based on the power supply information to obtain a target power supply rule; and transmitting the charging energy to the target vehicle based on the target power supply rule.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0021] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0022] Example 1

[0023] According to an embodiment of the present invention, a method for charging an electric vehicle is provided. It should be noted that the steps shown in the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions. Furthermore, although a logical order is shown in the flowchart, in some cases, the steps shown or described may be executed in a different order than that shown here.

[0024] Figure 2 This is a flowchart of an electric vehicle charging method according to an embodiment of the present invention, such as... Figure 2 As shown, the method includes the following steps:

[0025] Step S102: Receive the charging signal from the target vehicle;

[0026] Step S104: Analyze and process the above charging signals to determine the charging demand;

[0027] Step S106: Receive charging power from the wireless power source;

[0028] Step S108: Based on the above charging requirements, the above charging power is transmitted to the above target vehicle.

[0029] According to an embodiment of the present invention, an electric vehicle charging system is provided, characterized in that it includes: a wired charging pile for receiving a charging signal from a target vehicle and analyzing and processing the charging signal to determine the charging demand; a wireless power source for transmitting charging energy to the wired charging pile; and the wired charging pile for transmitting the charging energy to the target vehicle based on the charging demand.

[0030] In this embodiment of the invention, the electric vehicle charging method in steps S102 to S108 is executed by an electric vehicle charging system. The system receives the charging signal from the target vehicle; analyzes and processes the charging signal to determine the charging demand; receives charging power from a wireless power source; and transmits the charging power to the target vehicle based on the charging demand.

[0031] As an optional embodiment, such as Figure 3 The diagram shows a wireless-to-wired charging structure. 1 is the wireless charging primary converter coil, and 2 is the high-frequency AC rectifier. 1 and 2 together constitute a power supply based on the transmitting and receiving coils. This power supply serves as the power source for the wired charging (3). To charge the electric vehicle (4), the wired charging station needs to meet the relevant technical standards for wired charging.

[0032] In one optional embodiment, the above-mentioned analysis and processing of the charging signal to determine the charging demand includes: using the control equipment in the wired charging pile to control the adjustment equipment to perform real-time analysis and processing of the charging signal to determine the real-time charging demand of the target vehicle; and determining the charging demand based on the real-time charging demand.

[0033] In one optional embodiment, the above-mentioned transmission of charging energy to the target vehicle based on the charging demand includes: determining power supply information based on the charging demand; adjusting the charging energy based on the power supply information to obtain a target power supply rule; and transmitting the charging energy to the target vehicle based on the target power supply rule.

[0034] Optionally, during the charging process in the automated parking garage, changes in the positions of the primary and secondary transformer coils, or changes in the power supply at wireless point 1, may cause changes in the output voltage at point 2 (the DC power supply). Since electric vehicle charging requires real-time communication and a suitable charging voltage and current, a wired charging pile (point 3) is added between point 2 and the electric vehicle as a buffer. Point 3-1's DC-DC converter can accept a wide DC input range, and the DC-DC module self-adjusts to meet the charging needs of the electric vehicle. The DC-DC device is controlled by the charging controller (point 3-2). By adding the DC-DC device, there is no need to worry about changes in the AC input voltage of the wireless power transmission section, changes in the distance between the primary and secondary sides, or the reliability of communication between the primary and secondary sides, which could cause voltage fluctuations on RL. In this embodiment of the invention, it is only necessary to establish power transmission through primary transformer 1 and secondary transformer 2; engineering applications can be achieved without much further consideration.

[0035] Through the above steps, it is possible to receive wireless power from the wireless charging primary transformer coil and high-frequency AC rectifier through the wired charging pile and output it to the DC-DC converter. This eliminates the need for real-time adjustments to the high-frequency AC rectifier equipment and can stably meet the wired charging requirements of electric vehicles.
