Description

Technical Field

[0001] This invention relates to the field of power supply technology, specifically to an automatic control method for switching power supplies. Background Technology

[0002] With the increasing popularity of electric vehicles, shared charging stations have become an important part of urban infrastructure. However, the operation of charging stations faces many challenges, such as low charging efficiency, opaque charging fee calculation, and unreasonable allocation of charging resources. These problems not only affect the user's charging experience but also increase the operating costs of charging stations.

[0003] Existing charging station management systems often lack intelligent charging power control and charging phase management, leading to risks of energy waste and battery damage during charging. Furthermore, charging fees are typically calculated based on simple electricity metering, failing to consider the impact of charging speed and time on costs, resulting in unreasonable pricing.

[0004] Therefore, developing an automatic control method for switching power supplies is of great significance for improving the operational efficiency of charging stations, optimizing the allocation of charging resources, and enhancing the user charging experience. This new method needs to be able to intelligently control the charging power and charging stage based on the power information and charging fee information of the charging interface, while providing transparent charging cost calculation to ensure that the charging process is both efficient and economical. Through this method, intelligent management of charging stations can be achieved, improving charging efficiency, reducing operating costs, and enhancing user satisfaction. Summary of the Invention

[0005] This invention provides an automatic control method for switching power supplies, which helps to solve the problems mentioned in the background art.

[0006] This invention provides the following technical solution: an automatic control method for a switching power supply, comprising:

[0007] Obtain charging information from shared charging stations, including charging interface power information and charging fee information;

[0008] The shared charging station is equipped with multiple charging ports, and each charging port is equipped with a switching power supply.

[0009] The switching power supply is used to control the charging power and the start and stop of the charging power supply during the charging process of the vehicle.

[0010] Based on the charging interface power information and charging fee information, the power of the charging interface and the corresponding fee for each power are divided.

[0011] The charging process of the vehicle is divided into two stages: the first stage and the second stage.

[0012] The charging phases of the vehicle are allocated based on the vehicle's remaining battery power when it is connected to the charging port.

[0013] By using shared charging stations, the remaining battery power of the vehicle can be obtained when the user plugs the vehicle into the charging port.

[0014] Based on the vehicle's remaining battery power, the time required for the vehicle to be charged to the user-set target battery power at the first-level charging power is obtained and recorded as the target time.

[0015] The user-set target charge level is such that when the vehicle reaches the target charge level, the switching power supply will turn off the charging power, and the vehicle will stop charging.

[0016] By using shared charging stations, the moment when a user connects the vehicle to the charging port is recorded as the first moment, and the moment when the user sets the time to retrieve the vehicle is recorded as the second moment.

[0017] Based on the first and second moments, obtain the time interval between these two moments and record it as the actual time;

[0018] The power allocation strategy is set, which is divided into the first power allocation strategy and the second power allocation strategy;

[0019] If the actual time is longer than the target time, the first power allocation strategy is applied to the vehicle.

[0020] If the actual time is less than the target time, the second power allocation strategy is applied to the vehicle.

[0021] Optionally, the step of classifying the power of the charging interface and the corresponding charge based on the charging interface power information and charging charge information includes:

[0022] Obtain charging interface power information and classify the charging interface power in the shared charging station, specifically as follows:

[0023] Level 1 power, with a power range of [0W, 200W];

[0024] Level 2 power, with a power range of [200W, 300W];

[0025] Three power ratings, with a power range of [300W, 500W];

[0026] During the charging process, charging is performed according to the maximum value of each power level range;

[0027] The charging fee varies depending on the power level within a given time period.

[0028] A standard rate is set based on the allocated charging interface power, as follows:

[0029] The standard rate for Level 1 power is set at Q, the standard rate for Level 2 power is set at W, and the standard rate for Level 3 power is set at E.

[0030] The standard fee rate is the charge per kilowatt-hour for overcharging of a vehicle, expressed in yuan per kilowatt-hour.

[0031] Furthermore, the charging phases of the vehicle during the charging process are divided into a first phase and a second phase, including:

[0032] The first stage is as follows: after the vehicle is connected to the charging interface, it is charged by the switching power supply according to the recommended charging interface power. When the vehicle's battery level reaches 90%, the time is recorded and recorded as the end time of the first stage.

[0033] Based on the charging interface power, obtain the target charging cost and corresponding charging time for the vehicle in the first stage.

[0034] The second stage involves charging the vehicle when its current battery level is 90%. If the current battery level is less than the target battery level set by the user, the charging power is adjusted by the power supply to charge the vehicle until the target battery level is reached.

[0035] Optionally, obtaining the target charging cost and corresponding charging time for the vehicle in the first phase includes:

[0036] Calculate the charging costs for the vehicle during the first stage of charging, based on charging power levels one through three.

[0037] Charging cost calculation formula: Charging cost = Charging power × Charging time × Standard rate for the corresponding power level;

[0038] Based on the charging cost calculation formula, the charging cost corresponding to each power level is calculated and recorded as the first cost, the second cost and the third cost respectively.

[0039] Sort the first, second, and third costs in ascending order to form a cost sorting sequence;

[0040] And select the charging cost that ranks first in the cost sorting, and record it as the target charging cost;

[0041] Obtain the charging time corresponding to the target charging cost, and record it as the first time.

[0042] Furthermore, the allocation of charging stages for the vehicle based on its remaining battery power includes:

[0043] If the vehicle's remaining battery level is less than 90%, the vehicle will be set to charge in the first and second stages.

[0044] If the vehicle's remaining battery power is above 90% but below 100%, the vehicle will be set to charge in the second stage.

[0045] If the vehicle's remaining battery power reaches 100%, the charging power will be turned off by switching the power supply on and off.

[0046] Optionally, if the actual time is longer than the target time, then the first power allocation strategy is executed on the vehicle, including:

[0047] If a vehicle's charging phase includes both Phase 1 and Phase 2, then the vehicle is classified as a Class 1 vehicle.

[0048] Obtain the time required for the first type of vehicle to be charged at the first power level in the second phase;

[0049] Obtain the target charging cost and corresponding charging time for the first type of vehicle in the first phase;

[0050] The charging time and corresponding charging power of the first stage and the charging time and corresponding charging power of the second stage are set as the power allocation strategy for the first type of vehicle during the charging process.

[0051] If a vehicle's charging phase only includes the first phase, then the vehicle is classified as a Class 2 vehicle.

[0052] Obtain the time required for the second-class vehicle to charge in the first phase;

[0053] The charging time and corresponding charging power of the first stage are set as the power allocation strategy for the second type of vehicle during the charging process.

[0054] If a vehicle's charging phase only includes the second phase, then the vehicle is classified as a third-class vehicle.

[0055] The time required for a third-class vehicle to use the first power charging in the second phase;

[0056] The charging time and corresponding charging power of the second stage are set as the power allocation strategy for the third type of vehicle during the charging process.

[0057] Furthermore, if the actual time is less than the target time, a second power allocation strategy is implemented for the vehicle, including:

[0058] If a vehicle's charging phase includes both Phase 1 and Phase 2, then the vehicle is classified as a Class 4 vehicle.

[0059] If the time required to charge a Category 4 vehicle to the target charge level using Level 3 power is greater than the actual time, then Level 3 power will be selected for charging the Category 4 vehicle in both the first and second stages.

[0060] If a vehicle's charging phase only includes the first phase, then the vehicle is classified as a Class 5 vehicle.

[0061] Get the time required for a Category 5 vehicle to charge to the target power using Level 3 power. If it is longer than the actual time, then select Level 3 power for the first stage of charging for the Category 5 vehicle. If it is shorter than the actual time, then get the target charging cost and the first time for the Category 5 vehicle in the first stage.

[0062] If the first time of the fifth category vehicle is longer than the actual time, then the third power level will be selected for charging in the first stage of the fifth category vehicle.

[0063] If the first time of a Category 5 vehicle is less than the actual time, then in the first stage of the Category 5 vehicle, the charging power corresponding to the target charging cost will be selected for charging.

[0064] If a vehicle's charging phase only includes the second phase, then the vehicle is classified as a Class 6 vehicle.

[0065] Get the time required for the sixth category vehicle to charge to the target power using the third-level power. If it is longer than the actual time, then select the third-level power for the second stage of charging the sixth category vehicle. If it is shorter than the actual time, then get the target charging cost and the first time for the sixth category vehicle in the second stage.

[0066] If the first time of the sixth category vehicle is longer than the actual time, then the third power level will be selected for charging in the second stage of the sixth category vehicle.

[0067] If the first time for a Category 6 vehicle is less than the actual time, then in the second phase for the Category 6 vehicle, the charging power corresponding to the target charging cost will be selected for charging.

[0068] The present invention has the following beneficial effects:

[0069] 1. This automatic control method for switching power supplies acquires power and charging information from the charging interfaces, configures a switching power supply for each interface, and controls the charging power of the vehicle during the charging process to achieve the lowest possible cost. This ensures both charging efficiency and cost-effectiveness by dividing the charging process into two stages: a first stage of rapid charging to 90%, followed by a second stage of trickle charging based on actual conditions. This phased management helps reduce battery damage. The charging stage is allocated based on the vehicle's remaining charge upon connection and the user-set target charge level, ensuring the charging process meets user needs without excessive resource consumption. Based on actual and target times, the switching power supply selects either a first or second power allocation strategy to ensure optimal charging within a limited time. Users can set the time to remove the vehicle, and the charging plan is adjusted according to their schedule, improving the user's charging experience. The second-stage trickle charging strategy helps protect the battery, preventing overcharging and extending battery life.

[0070] 2. This automatic control method for switching power supplies clearly divides the power of the charging interface into different levels, providing power management for different types of electric vehicles. This ensures that the charging process is both efficient and safe. Different standard rates are set for each power level, enabling a more flexible charging strategy. The switching power supply can select the appropriate power level for charging based on the user's charging needs and time. By charging according to the maximum value of each power level, it ensures that the charging station's charging capacity is fully utilized during the charging process, thereby improving the utilization efficiency of charging resources.

[0071] 3. This automatic control method for switching power supplies can quickly charge the vehicle's battery to 90% by providing the recommended charging interface power to the vehicle in the first stage, thereby providing a large amount of power to the vehicle in the shortest time and improving charging efficiency. The charging process is divided into two specific stages. In the second stage, if the vehicle's current battery level has not reached the user-set target battery level, the charging power can be automatically adjusted to continue charging to ensure that the battery level meets the user's needs. The target charging cost and corresponding charging time are obtained in the first stage, and the charging power adjustment strategy in the second stage can adjust the charging speed according to the remaining battery level and the remaining charging time.

[0072] 2. This automatic control method for switching power supplies provides users with detailed charging costs by calculating the charging costs at different power levels. This helps users understand the charging costs under different charging options and forms a cost ranking sequence. Users can see the cost comparison of charging at different power levels, and the switching power supply can then make a charging choice with the lowest cost. The charging cost ranked first is selected as the target charging cost, and the charging time corresponding to the target charging cost is obtained. This time is then used to select the lowest cost scheme for charging in the first or second stage.

[0073] 3. This automatic control method for switching power supply detects the remaining battery power of the vehicle and allocates charging stages accordingly. For vehicles with less than 90% battery power, the first stage of fast charging is arranged, followed by the second stage of trickle charging. For vehicles with more than 90% battery power, the second stage of charging is initiated. When the vehicle's battery power reaches 100%, the charging power is automatically turned off to prevent overcharging, protect the battery, and extend its service life.

[0074] 2. This automatic control method for switching power supplies determines the charging strategy by judging whether the actual time exceeds the target time, ensuring that the charging plan matches user needs and time constraints, and optimizing the charging plan. Vehicles are divided into three categories according to different charging stage needs, and corresponding power allocation strategies are formulated for each category. For the first category of vehicles, since there is enough time to reach the target charge, a higher charging power can be used to improve charging efficiency. For the second category of vehicles, since the target charge is less than 90%, charging is ensured to be completed within a limited time to meet the user's charging needs. For the third category of vehicles, where the remaining charge is already high, charging is ensured to reach the target charge.

[0075] 3. This automatic control method for switching power supplies assesses whether the actual charging time is sufficient. In cases of time constraints, vehicles are categorized into four, five, and six categories based on different charging needs and time limitations. For category four vehicles, charging is performed using three levels of power to provide more electricity within a limited time. For category five and six vehicles, a trade-off is made between charging cost and time, selecting the most suitable charging power to achieve the user's target charging cost and time requirements.

[0082] The charging process of the vehicle is divided into two stages: the first stage and the second stage.

[0083] After the vehicle is connected to the charging port, it begins the first stage of charging until the vehicle's battery level reaches 90%. Once the battery level reaches 90%, this time point is recorded, marking the end of the first stage.

[0084] After the first stage is completed, the vehicle enters the second stage of charging. In this stage, the power supply switches the power and controls the charging process to protect the battery and extend its life. This stage of charging will continue until the vehicle is fully charged, that is, 100%.

[0085] The charging phases of the vehicle are allocated based on the vehicle's remaining battery power when it is connected to the charging port.

[0086] By using shared charging stations, the remaining battery power of the vehicle can be obtained when the user plugs the vehicle into the charging port.

[0087] Based on the vehicle's remaining battery power, the time required for the vehicle to be charged to the user-set target battery power at the first-level charging power is obtained and recorded as the target time.

[0104] The standard fee rate is the charge per kilowatt-hour for overcharging of a vehicle, expressed in yuan per kilowatt-hour.

[0105] Furthermore, the charging phases of the vehicle during the charging process are divided into a first phase and a second phase, including:

[0106] The first stage is as follows: after the vehicle is connected to the charging interface, it is charged by the switching power supply according to the recommended charging interface power. When the vehicle's battery level reaches 90%, the time is recorded and recorded as the end time of the first stage.

[0107] Based on the charging interface power, obtain the target charging cost and corresponding charging time for the vehicle in the first stage.

[0108] The second stage is that when the vehicle's current battery level is 90%, if the current battery level is less than the target battery level set by the user, the charging power is adjusted by the switching power supply to charge the vehicle until the battery level reaches the target battery level.

[0109] Optionally, obtaining the target charging cost and corresponding charging time for the vehicle in the first phase includes:

[0110] Calculate the charging costs for the vehicle during the first stage of charging, based on charging power levels one through three.

[0111] Charging cost calculation formula: Charging cost = Charging power × Charging time × Standard rate for the corresponding power level, where the unit of charging power is kilowatt-hours / hour, the unit of charging time is hours, and the unit of standard rate for the corresponding power level is yuan / kilowatt-hour.

[0112] Based on the charging cost calculation formula, the charging cost corresponding to each power level is calculated and recorded as the first cost, the second cost and the third cost respectively.
