Technical Field

[0001] This application relates to the field of new energy technology, and in particular to a charging control method and related equipment. Background Technology

[0002] Currently, with increasing global emphasis on environmental protection and adjustments to the energy structure, electric vehicles, as a clean and efficient mode of transportation, are gradually becoming the future trend of transportation development. The promotion of electric vehicles not only helps reduce exhaust emissions and air pollution but also reduces dependence on traditional fossil fuels, achieving sustainable development. Therefore, the construction of charging stations is crucial to meeting the charging needs of electric vehicles.

[0003] However, current charging station pricing methods vary, including billing based on electricity consumption, time, power consumption, and peak / valley times, as well as occupancy fees for vehicles not moved after charging. User charging time is primarily limited by the charging station's capacity and the battery pack's charging capability, while the scope for user-defined settings is limited. Therefore, it is necessary to propose a charging control method to at least address some of the aforementioned issues. Summary of the Invention

[0038] If the predicted charging time reaches the target charging time, a successful charging result is generated and the charging result is fed back to the user.

[0054] Please see Figure 1 This is a schematic flowchart of a charging control method provided in an embodiment of this application, which may specifically include:

[0055] S110. In response to the target electric vehicle connecting to the target charging pile, obtain charging-related parameters, including the current battery level, target battery level, and target charging duration of the target electric vehicle.

[0056] For example, when a target electric vehicle connects to a target charging station, it means the vehicle is ready to charge. The charging-related parameters are then obtained, including the target electric vehicle's current battery level, target battery level, and target charging time. The current battery level refers to the remaining charge in the target electric vehicle's battery when connected to the charging station. The target battery level is the amount of charge the target electric vehicle's battery needs to reach, as set by the user. The target charging time is the expected charging time required for the target electric vehicle to reach the target battery level from its current charge level. This target charging time is set by the user according to their schedule.

[0057] S120. Obtain the charging billing method, obtain the default charge amount corresponding to the charging billing method, and determine the reference charge amount corresponding to the charging billing method based on the charging-related parameters.

[0058] For example, different users will choose different charging billing methods, including power consumption billing, time-based billing, power-based billing, and time-based billing. Users can freely choose the charging method according to their needs. For each charging billing method, the battery management system (BMS) will use the charging station brand, geographical location, and pre-calculated charges as the default charge. The default charge is to allow users to understand the approximate charging cost before charging and to determine the reference charge corresponding to the charging billing method based on the obtained charging-related parameters.

[0059] S130. If the default charge amount is greater than the reference charge amount, the charging current of the target charging pile is obtained based on the charging billing method and the charging-related parameters.

[0060] For example, when the default charge is greater than the reference charge, it means that the expected charge calculated according to the current billing method and related parameters will be lower than the default charge level set by the target charging station. This proves that the default charge level set by the target charging station is too high. This is because the operator of the target charging station has adjusted the charging standard, or because the cost has changed due to market changes or other reasons. In this case, the user can manually fill in the new amount. This means that the user can manually enter the updated charge amount to ensure the accuracy of the billing. The Battery Management System (BMS) will automatically store this updated charge value for use in subsequent charging processes. This ensures that the system can always reflect the latest charging situation, improving the flexibility and adaptability of billing. At the same time, the charging current of the target charging station is calculated based on the user's selected charging billing method, the user's set target power, and the user's set target charging duration.

[0061] S140. Charge the target electric vehicle based on the charging current until the target electric vehicle reaches the target power level or target charging time.

[0062] For example, during the charging process, the target charging station will continuously charge the target electric vehicle according to the determined charging current until the target power or target charging time set by the user is reached, so as to ensure the safety and rationality of charging, while meeting the user's charging needs and restrictions.

[0063] In summary, the charging control method proposed in this application calculates the minimum charging current of the target charging pile based on the target charging duration set by the user and the charging billing method selected by the user, and charges the target electric vehicle based on the minimum charging current. This allows users to charge according to their own schedules, and provides a high degree of user autonomy in setting the charging method.

[0064] In some examples, the charging billing method includes electricity billing, and the step of determining the reference charge amount corresponding to the charging billing method based on charging-related parameters includes:

[0065] Get the charging power and unit electricity cost;

[0066] The power coefficient is obtained by dividing the predicted charging time by the target charging time.

[0067] Multiply the charging amount by the unit electricity cost to obtain the total cost;

[0068] Multiply the power consumption coefficient by the total cost to obtain the reference charge.

[0069] For example, when the charging billing method is determined to be energy consumption-based, it is necessary to obtain the charging volume and the unit electricity cost. The charging volume can be obtained through the metering device of the target charging station or the battery management system (BMS) of the electric vehicle, representing the amount of electricity consumed during this charging process, usually in kilowatt-hours (kWh). The unit electricity cost refers to the price per unit of energy, which is generally determined by the power supply department or the operator of the target charging station and may vary depending on factors such as region and time of day.

[0070] Predicted charging time is an estimate of the time required to complete charging based on the current charging status and parameters. Target charging time is the user-defined desired charging time. Dividing the predicted charging time by the target charging time yields a capacity coefficient. This coefficient reflects the ratio between the actual charging time and the target charging time.

[0071] By multiplying the collected charging volume by the unit electricity cost, the total cost can be calculated based on the actual electricity consumption and the unit electricity cost, without considering the power consumption coefficient. Finally, multiplying the power consumption coefficient by the total cost yields a reference charge. This reference charge takes into account the impact of the difference between the actual charging time and the target charging time on the cost.

[0072] In some examples, the charging billing method includes time-based charging, and the step of determining the reference charge amount corresponding to the charging billing method based on charging-related parameters includes:

[0073] Get charging time, unit electricity cost, and occupancy fee;

[0074] Multiply the charging time by the unit electricity cost to obtain the charging fee;

[0075] The charging fee and the space reservation fee are summed to obtain a reference charge.

[0076] For example, when the charging billing method is determined to be time-based, it is necessary to obtain the charging duration, unit electricity cost, and occupancy fee. Charging duration refers to the time from the start of charging to the expected end, usually measured in hours. The unit electricity cost under time-based billing is the hourly electricity price. The occupancy fee is an additional charge incurred if the target electric vehicle continues to occupy the target charging station's location after charging is complete; its purpose is to encourage users to move their vehicles promptly and improve the utilization efficiency of the charging stations.

[0077] Multiplying the charging time by the unit electricity cost allows you to calculate the cost based solely on charging time—the charging fee. This is the core of time-based billing, reflecting the time cost of using the target charging station. The charging fee is then summed with a occupancy fee; if occupancy occurs during or after charging, a occupancy fee is added to arrive at the final reference charge. This ensures that users consider not only the cost of charging time but also the additional costs incurred by prolonged occupancy, thus encouraging rational use of charging facilities and improving the utilization rate of charging stations.

[0078] In some examples, the charging billing method includes power-based billing, and the step of determining the reference charge amount corresponding to the charging billing method based on charging-related parameters includes:

[0079] Obtain the charging power and real-time voltage for each zone;

[0080] Divide the charging power of each interval by the real-time voltage to obtain the charging current of each interval;

[0081] The unit electricity cost for each interval is determined based on the charging current of each interval.

[0082] The target charging cost is obtained by multiplying the charging power of each interval by the unit electricity cost.

[0083] The target charging cost and the space reservation fee are summed to obtain a reference charge.

[0084] For example, when the charging billing method is determined to be power-based billing, it is necessary to first obtain the charging power and real-time voltage for each interval. Charging power represents the energy input per unit time during the charging process, usually measured in kilowatts (kW). Since the power varies in different intervals during charging, it is necessary to obtain the charging power for each interval. Real-time voltage refers to the actual voltage value during charging, usually measured in volts (V), which varies with factors such as the charging state and grid conditions.

[0085] By dividing the charging power of each zone by the real-time voltage, the corresponding charging current for each zone can be obtained. Based on the charging current of each zone, the unit electricity cost for each zone can be determined. For each zone, multiplying the charging power of that zone by the corresponding unit electricity cost yields the charging fee for that zone. Then, the charging fees for all zones are summed to obtain the target charging fee. This target charging fee is calculated based on the charging power and unit electricity cost of different zones, more accurately reflecting the actual charging cost. Finally, the target charging fee is summed with a reservation fee. If there is any reservation fee during or after charging, it needs to be added to obtain the final reference charge.

[0086] In the actual calculation, the minimum charging power value is used first to calculate the required charging time. If the calculated charging time does not meet the actual needs (e.g., the user wants to complete charging within a certain time), the system switches to the next higher charging power value and calculates the charging time again. This process is repeated until the calculated charging time meets the requirements. Throughout the calculation process, it is crucial that the charging power does not exceed the battery's allowable power. This is to protect the battery and prevent damage caused by excessive power input. If the selected charging power exceeds the battery's allowable power, it may lead to problems such as battery overheating, shortened lifespan, or even damage.

[0087] In some examples, the charging billing method includes time-of-use billing, and the step of determining the reference charge amount corresponding to the charging billing method based on charging-related parameters includes:

[0088] Obtain the electricity consumption for each time period and the corresponding electricity cost for each time period;

[0089] Multiply the electricity consumption in each time period by the electricity cost in that time period to obtain the target electricity cost;

[0090] The target electricity cost and the occupancy fee are summed to obtain a reference charge.

[0091] For example, when the charging billing method is determined to be time-of-use (TOU), it is necessary to first obtain the electricity consumption for each time period and the corresponding electricity cost for each time period. The electricity consumption for each time period refers to the electricity consumed during charging within different time periods, usually measured in kilowatt-hours (kWh). The electricity cost for each time period refers to the electricity price corresponding to different time periods, also expressed as the price per kilowatt-hour. Because the power supply and demand situation varies at different times, the electricity price will also differ.

[0092] For each time period, multiply the electricity consumption during that period by the corresponding electricity price to obtain the electricity cost for that period. Then, sum the electricity costs for all time periods to obtain the target electricity cost. This target cost is calculated based on the electricity consumption and price for different time periods, more accurately reflecting the actual charging cost. Finally, sum the target cost with the space reservation fee. If there is space reservation during or after charging, the reservation fee needs to be added to obtain the final reference charge.

[0093] In some examples, the step of obtaining the charging current of the target charging pile based on the charging billing method and the charging-related parameters includes:

[0094] Obtain battery high temperature and battery low temperature readings;

[0095] The voltage range is obtained based on the target battery capacity and the target charging time;

[0096] The first charging current value is obtained by filtering based on the battery temperature and the voltage range.

[0097] The second charging current value is obtained by filtering based on the battery's low temperature and voltage range.

[0098] When the first charging current value is less than the second charging current value, the first charging current value is the charging current;

[0099] When the first charging current value is greater than the second charging current value, the second charging current value is the charging current.

[0100] For example, after the target electric vehicle and the target charging station interact, the vehicle's Battery Management System (BMS) can obtain the maximum output voltage, maximum output current, and maximum output power of the target charging station. First, considering the battery at its highest temperature (i.e., high battery temperature), and combining this with the current State of Charge (SOC) range (or voltage range, as SOC and voltage have a certain correlation), a first charging current value is obtained by consulting a pre-set table. This first charging current value is considered a suitable charging current under the battery's highest temperature and a specific SOC or voltage range, ensuring that charging is both efficient and safe under these conditions, without damaging the battery due to high temperature and high current. Here, SOC represents the battery's state of charge, indicating the percentage of remaining battery capacity. The voltage range is derived from the target battery capacity and the target charging time.

[0101] Next, considering the battery at its lowest temperature, i.e., low battery temperature, and again combining this with the current SOC range (or voltage range), a second charging current value is obtained by consulting a pre-set table. At low temperatures, battery performance is affected, so it's necessary to select an appropriate charging current to avoid adverse effects on the battery while ensuring a certain charging efficiency.

[0102] Finally, to ensure the safety and stability of the charging process, the smaller value between the first and second charging current values ​​is selected as the charging current for that specific SOC range (or voltage range). This is done because, regardless of high or low temperature conditions, the most conservative charging current is prioritized to maximize battery protection and prevent damage from excessive current. This method comprehensively considers the battery's characteristics and charging requirements at different temperatures to achieve safe and efficient charging.

[0103] In some examples, the step of charging the target electric vehicle based on the charging current until the target battery capacity or target charging time of the target electric vehicle is reached includes:

[0104] The predicted charging time is determined based on the charging current;

[0105] If the predicted charging time reaches the target charging time, a successful charging result is generated and the charging result is fed back to the user.

[0106] If the predicted charging time is less than the target charging time, the predicted charging time will be fed back to the user.

[0107] For example, the predicted charging time can be determined based on the currently determined charging current. This predicted charging time is the estimated time required for the battery to charge to the target capacity under the current charging current. If the calculated predicted charging time is equal to the user-set target charging time, it means the charging settings meet the user's expectations. At this point, a successful charging result is generated, which may include information such as "Charging settings successful, charging will proceed according to the target charging time," and this result is fed back to the user. The user can receive this feedback through channels such as the in-vehicle display screen or a mobile app to understand the status of the charging settings.

[0108] If the predicted charging time is less than the target charging time, it means that even using the lowest stable charging current output by the target charging station, the user's desired charging time cannot be achieved. In this case, the system will provide feedback on the longest charging time, i.e., the predicted charging time, to the user. This predicted charging time is the longest charging time achievable under the current conditions using the lowest charging current. Providing this predicted charging time feedback to the user allows them to understand the actual charging situation. After receiving the feedback on the longest charging time, the user has two options: First, adjust the target SOC upwards, i.e., increase the target capacity, which increases the rechargeable amount and makes the charging time more suitable for their needs. Second, return to the vehicle as soon as possible according to the system's recommended time. This allows users to flexibly adjust their charging plan according to the actual situation to better meet their needs.

[0109] like Figure 2 As shown, this application proposes a charging control system, which includes: a data acquisition module 21, a calculation module 22, and a charging module 23;

[0110] The data acquisition module 21 is configured to: in response to the target electric vehicle accessing the target charging pile, acquire charging-related parameters, including the current battery level, target battery level, and target charging duration of the target electric vehicle; acquire the charging billing method, acquire the default charge amount corresponding to the charging billing method, and determine the reference charge amount corresponding to the charging billing method based on the charging-related parameters;

[0111] The calculation module 22 is configured to: when the default charge amount is greater than the deviation value of the reference charge amount, obtain the charging current of the target charging pile based on the charging billing method and the charging-related parameters;

[0112] The charging module 23 is configured to charge the target electric vehicle based on the charging current until the target electric vehicle reaches its target battery level or target charging time.
