[0042] Hereinafter, exemplary embodiments according to this application will be described in detail with reference to the accompanying drawings. Obviously, the described embodiments are merely some embodiments of this application, and not all embodiments of this application. It should be understood that this application is not limited to the exemplary embodiments described herein.

[0043] Figure 1 This is a schematic flowchart of a voltage adjustment method based on a charging pile provided in an exemplary embodiment of this application. Figure 1 As shown, the voltage adjustment method based on charging piles includes:

[0044] Step 110: Obtain the mains voltage of the input charging pile.

[0045] The power system transmits electricity to the charging piles. The power supply standard at the end of the power system can be a three-phase four-wire system, meaning the secondary side of the power supply transformer at the end uses a star connection with the neutral point grounded and serving as the neutral output. The power system delivers the actual input voltage to the charging pile, which then charges the connected battery using this actual input voltage. The mains voltage is drawn from the government power grid, and the mains voltage fluctuation range can be 180V-250V.

[0046] Step 120: Obtain the charging curve corresponding to the battery of the current electric vehicle.

[0047] The electric vehicle's battery currently sends its charging curve to the charging station so that the charging station can determine the required charging voltage for the connected battery. The electric vehicle's battery is connected to the charging station via a data bus, and the battery sends its own parameters to the charging station.

[0048] Step 130: Based on the charging curve and the mains voltage, construct a stable charging curve for the power supply circuit of the charging pile to supply power to the battery of the current electric vehicle.

[0049] In the embodiments of this application, the battery is typically charged by gradually increasing the voltage. Since the charging voltage in the charging curve varies with the mains voltage, the battery may be damaged during the charging process due to the mains voltage. Therefore, it is necessary to establish a stable charging curve and charge the battery through this curve to prevent damage during the charging process.

[0050] Step 140: Power the battery of the current electric vehicle according to the stable charging curve.

[0051] Based on the battery's required charging voltage and the mains voltage provided by the power system, the actual output voltage supplied to the battery is adjusted to avoid large errors in the actual input voltage to the electric vehicle's battery caused by voltage fluctuations. In other words, the actual output voltage can be approximately equal to the battery's required charging voltage. The DC voltage can be 12, 24, 36, 48, 60, or 72V, and the AC voltage can be 220V.

[0052] This application provides a voltage adjustment method based on a charging pile. The method includes: obtaining the mains voltage of the charging pile; obtaining the charging curve corresponding to the battery of the current electric vehicle; constructing a stable charging curve for the power supply circuit of the charging pile to supply power to the battery of the current electric vehicle based on the charging curve and the mains voltage; and supplying power to the battery of the current electric vehicle based on the stable charging curve, thereby avoiding large errors in the actual input voltage to the battery of the current electric vehicle caused by voltage fluctuations, which could directly lead to battery burnout.

[0053] Figure 2 This is a schematic flowchart of an exemplary embodiment of the present application providing a method for adjusting the actual output voltage. Figure 2 As shown, step 130 may include:

[0054] Step 131: Convert the mains voltage to DC voltage.

[0055] The voltage supplied to the battery is usually DC, therefore, the AC mains voltage can be converted to DC. This can be done using a rectifier. Step 132: Based on the DC voltage and the charging curve, construct a stable charging curve for the power supply circuit of the charging pile to the battery of the current electric vehicle.

[0056] The DC voltage is the highest voltage value on the charging curve. Exceeding this DC voltage will cause the battery to burn out. Furthermore, by stabilizing the charging curve, voltage fluctuations are avoided, which could lead to a large error in the actual input voltage to the battery of the current electric vehicle. In other words, the actual output voltage can be made approximately equal to the charging voltage required by the battery.

[0057] Step 132: Based on the DC voltage and charging curve, construct a stable charging curve for the power supply circuit of the charging pile to the battery of the current electric vehicle.

[0058] By using DC voltage and charging curves, a stable charging curve is constructed for the power supply circuit of the charging pile to the battery of the current electric vehicle, thereby ensuring the stability of battery charging.

[0059] Figure 3 This is a flowchart illustrating an actual output voltage adjustment method provided in another exemplary embodiment of this application. For example... Figure 3 As shown, step 132 may include:

[0060] Step 1321: Adjust the duty cycle corresponding to the DC voltage to obtain a stable voltage, where the stable voltage is the highest voltage supplied to the battery.

[0061] By adjusting the duty cycle corresponding to the DC voltage, a stable voltage is obtained. This stable voltage is the highest voltage at which the charging pile's power supply current supplies power to the battery.

[0062] To achieve a stable output voltage, pulse width modulation (PWM) control is used to regulate the duty cycle of the DC voltage by controlling the IGBT's control electrode (IGBT on / off time), thereby obtaining a stable AC voltage. Alternatively, PWM control can be used to regulate the duty cycle of the DC voltage by controlling the on / off time of the IGBT in the inverter, thus obtaining a stable AC voltage. The IGBT (Insulated Gate Bipolar Transistor) is a composite, fully controllable, voltage-driven power semiconductor device composed of a bipolar junction transistor (BJT) and an insulated-gate field-effect transistor (MOS).

[0063] Step 1322: Adjust the duty cycle corresponding to each voltage value in the charging curve to obtain the adjusted charging curve.

[0064] Adjust the duty cycle corresponding to each voltage value in the charging curve to obtain the adjusted charging curve. The duty cycle corresponding to each voltage value is different and cannot exceed the stable voltage value.

[0065] Step 1323: Construct a stable charging curve based on the adjusted charging curve and the stable voltage.

[0066] By adjusting the charging curve and stabilizing the voltage, a stable charging curve is constructed, so that the charging pile power supply circuit supplies power to the electric vehicle battery according to the stable charging curve.

[0067] In one embodiment, step 1323 can be specifically implemented as follows: setting a zero voltage value within a preset time period between each adjusted voltage value; constructing a stable charging curve based on the zero voltage value within the preset time period, the adjusted charging curve, and the stable voltage.

[0068] A preset time interval between each adjusted voltage value is established, representing a zero voltage value. In other words, during battery charging in the stable charging curve, the charging voltage is gradually increased, and a zero voltage is maintained between adjacent charging voltages to ensure stable battery charging. Because of this method, the stable charging curve includes a fluctuating curve, which consists of gradually increasing charging voltage and zero voltage intervals. This fluctuating curve provides a buffer time for battery charging, protecting the battery from damage caused by voltage fluctuations.

[0069] Figure 4 This is a schematic flowchart illustrating a method for obtaining charging voltage according to an exemplary embodiment of this application. Figure 4 As shown, step 120 may include:

[0070] Step 121: Obtain the battery verification information, which includes a verification code or a QR code.

[0071] The system retrieves verification information sent by the battery, which can be obtained via a verification code or QR code. The QR code can be placed on the battery casing, while the verification code can be stored in the battery's processor.

[0072] Step 122: If the verification information is successful, obtain the charging curve corresponding to the battery of the current electric vehicle.

[0073] Scan the QR code on the battery casing or obtain the verification code stored in the battery's processor. Then, decrypt the verification information to securely obtain the charging curve of the current electric vehicle's battery. If the verification information matches the preset verification information, for example, if the verification code is the same as the preset verification code, or the QR code is the same as the preset QR code, then the verification is successful, and the charging curve of the current electric vehicle's battery can be obtained.

[0074] In one embodiment, step 1321 can be specifically implemented as: adjusting the duty cycle corresponding to the DC voltage through a rectifier to obtain a stable AC voltage.

[0075] A rectifier is a device that converts alternating current (AC) into direct current (DC). It can be used in power supply systems and for detecting radio signals. Rectifiers can be made from vacuum tubes, ignition tubes, solid-state silicon semiconductor diodes, mercury arc diodes, etc. A stable voltage is obtained by adjusting the duty cycle of the DC voltage through the rectifier.

[0076] In one embodiment, the current battery charge of the electric vehicle is determined; based on a stable charging curve, the power supply circuit of the charging pile is controlled to sequentially increase the voltage value to supply power to the battery of the electric vehicle.
