[0054] See also Figure 1 , is a schematic diagram of a charging control method provided in an embodiment of the present application, which may specifically include:

[0055] S110, in response to the target electric vehicle being connected to the target charging pile, acquiring charging-related parameters, wherein the charging-related parameters include a current power level of the target electric vehicle, a target power level, and a target charging duration.

[0056] Exemplarily, when the target electric vehicle is connected to the target charging pile, it means that the electric vehicle is ready to be charged, and the charging-related parameters at this time are obtained, wherein the charging-related parameters include the current power of the target electric vehicle, the target power and the target charging time. The current power refers to the remaining power of the battery of the target electric vehicle when it is connected to the target charging pile. The target power is the power value that the battery of the target electric vehicle needs to be charged to set by the user. The target charging time is the length of time required for the target electric vehicle to be charged from the current power to the target power. This target charging time is set by the user according to his own schedule.

[0057] S120: Acquire a charging billing method, acquire a default charging amount corresponding to the charging billing method, and determine a reference charging amount corresponding to the charging billing method based on charging-related parameters.

[0058] For example, different users will choose different charging billing methods, including electricity billing, time-based charging, power-based charging and time-based charging. 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 pile brand, geographical location and statistical charging amount as the default charging amount. The default charging amount is to allow users to understand the approximate charging cost before charging, and can determine the reference charging amount corresponding to the charging billing method based on the obtained charging-related parameters.

[0059] S130: When the default charging amount is greater than the reference charging amount, obtaining a charging current of the target charging pile based on the charging billing method and the charging-related parameters.

[0060] Exemplarily, 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 for the target charging pile, proving that the default charge level set for the target charging pile is too high. This is because the target charging pile operator has adjusted the charging standards, or the fees have changed due to market changes and other reasons. At this time, the user can fill in the new amount on his own. 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 fee value for use in subsequent charging processes. This ensures that the system can always reflect the latest charging situation and improve the flexibility and adaptability of billing. At the same time, the charging current of the target charging pile is calculated based on the charging billing method selected by the user, the target power set by the user, and the target charging time set by the user.

[0061] S140: Charging the target electric vehicle based on the charging current until a target power level or a target charging time of the target electric vehicle is reached.

[0062] Exemplarily, during the charging process, the target charging pile will continue to 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 the embodiment of the present application calculates the minimum charging current of the target charging pile according to the target charging time 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, thereby achieving the purpose of allowing users to charge according to their own schedule, and the user has a high operating space for independent setting.

[0064] In some examples, the charging billing method includes electricity billing, and the step of determining a 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] Divide the predicted charging time by the target charging time to get the power coefficient;

[0067] Multiplying the charging amount by the unit electricity fee to obtain a total fee;

[0068] The reference charge amount is obtained by multiplying the electricity coefficient by the total cost.

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

[0070] The predicted charging time is the estimated time required to complete charging based on the current charging state and charging parameters. The target charging time is the expected charging time set by the user. Divide the predicted charging time by the target charging time to get a power coefficient. This coefficient reflects the ratio of the actual charging time to the target charging time.

[0071] By multiplying the obtained charging power by the unit electricity fee, the total fee calculated based on the actual power consumption and the unit electricity fee without considering the power factor can be calculated. Finally, multiply the power factor by the total fee to get the reference fee. This reference fee takes into account the impact of the difference between the actual charging time and the target charging time on the fee.

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

[0073] Get charging time, unit electricity cost and space charge;

[0074] The charging cost is obtained by multiplying the charging time by the unit electricity cost;

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

[0076] For example, when the charging billing method is determined to be a time-based charging method, it is necessary to obtain the charging time, unit electricity cost and occupancy fee. The charging time refers to the length of time from the start of charging to the expected end of charging, usually in hours. The unit electricity cost is the price of electricity per hour under the time-based charging method. The occupancy fee refers to the additional fee incurred if the target electric vehicle still occupies the position of the target charging pile after charging is completed. The purpose is to encourage users to move their vehicles in time and improve the efficiency of the use of charging piles.

[0077] By multiplying the charging time by the unit electricity fee, you can calculate the cost based solely on the charging time, that is, the charging fee. This is the core part of the time-based charging, which reflects the time cost of the user using the target charging pile. Sum the charging fee and the space fee. If there is a space occupied during or after charging, the space fee needs to be added to get the final reference charge amount. This ensures that when using the target charging pile, users must not only consider the cost of charging time, but also consider the additional costs that will be incurred if the target charging pile is occupied for a long time, thereby prompting users to use charging facilities reasonably and improve the utilization rate of charging piles.

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

[0079] Obtain the charging power and real-time voltage of each interval;

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

[0081] Determine the unit electricity fee corresponding to each interval based on the charging current in each interval;

[0082] Multiplying the charging power in each interval by the unit electricity fee to obtain a target charging fee;

[0083] The target charging fee is added to the parking fee to obtain a reference charging amount.

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

[0085] By dividing the charging power of each interval by the real-time voltage, the charging current corresponding to each interval can be obtained. According to the charging current of each interval, the unit electricity fee corresponding to each interval can be determined. For each interval, multiply the charging power of the interval by the corresponding unit electricity fee to get the charging fee of the interval. Then add up the charging costs of each interval to get the target charging fee. This target charging fee is calculated based on the charging power and unit electricity fee of different intervals, and more accurately reflects the actual charging cost. Sum the target charging fee and the placeholder fee. If there is a placeholder during or after charging, the placeholder fee needs to be added to get the final reference charge amount.

[0086] Among them, in the actual calculation, the required charging time is calculated with the lowest charging power value first. If the calculated charging time cannot meet the actual demand (for example, the user hopes to complete the charging within a certain time), switch to the next higher charging power value to calculate the charging time again. This process is repeated until the calculated charging time meets the demand. During the entire calculation process, it is important to note that the charging power cannot exceed the power allowed by the battery. This is to protect the battery and prevent damage to the battery due to excessive power input. If the selected charging power exceeds the power allowed by the battery, it may cause problems such as battery overheating, shortened life, or even damage.

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

[0088] Obtaining the amount of electricity in each time period and the electricity charges for each time period corresponding to the amount of electricity;

[0089] Multiply the electricity amount in each time period by the electricity fee in each time period to obtain a target electricity fee;

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

[0091] For example, when it is determined that the charging billing method is a time-of-use billing method, it is necessary to first obtain the power consumption of each time period and the electricity charges of each time period corresponding to the power consumption. The power consumption of each time period refers to the power consumed by charging in different time periods, usually in kilowatt-hours (kWh). The electricity charges of each time period refer to the corresponding electricity prices in different time periods, also expressed in terms of price per kilowatt-hour. Due to the different power supply and demand conditions in different time periods, the electricity prices will also vary.

[0092] For each time period, multiply the amount of electricity in that time period by the corresponding electricity price to get the electricity fee for that time period. Then add up the electricity fees for each time period to get the target electricity fee. This target electricity fee is calculated based on the amount of electricity and electricity prices in different time periods, and more accurately reflects the actual charging cost. Sum the target electricity fee and the space charge. If there is space occupied during or after charging, the space charge needs to be added to get the final reference charge amount.

[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] Get battery high temperature and battery low temperature;

[0095] Obtaining a voltage range according to the target power and the target charging time;

[0096] Screening is performed according to the battery high temperature and the voltage range to obtain a first charging current value;

[0097] Screening is performed according to the low temperature of the battery and the voltage range to obtain a second charging current value;

[0098] In the case where the first charging current value is less than the second charging current value, the first charging current value is a charging current;

[0099] In the case where the first charging current value is greater than the second charging current value, the second charging current value is the charging current.

[0100] Exemplarily, after the target electric vehicle and the target charging pile 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 pile. First, consider the battery at the highest temperature, that is, the high temperature of the battery, combined with the current SOC range (or voltage range, because the battery's SOC and voltage have a certain correspondence), and filter by querying a pre-set table to obtain a first charging current value. This first charging current value is a charging current that is considered more appropriate at the highest battery temperature and a specific SOC or voltage range to ensure that charging in this case is both efficient and safe, and will not cause damage to the battery due to high temperature and high current. Among them, SOC is the state of charge of the battery, which indicates the proportion of the remaining battery power. The voltage range is obtained by the target power and the target charging time.

[0101] Next, consider the battery at the lowest temperature, that is, the battery low temperature, and also combine the current SOC range (or voltage range), and filter by querying the pre-set table to obtain the second charging current value. At low temperatures, the performance of the battery will be affected, and it is necessary to select a suitable charging current to avoid adverse effects on the battery, while also ensuring a certain charging efficiency.

[0102] Finally, in order to ensure the safety and stability of the charging process, the smaller value is selected from the first charging current value and the second charging current value as the charging current for the specific SOC interval (or voltage interval). The reason for this is that the most conservative charging current should be given priority regardless of high or low temperatures to maximize the protection of the battery and prevent damage to the battery due to excessive current. This method comprehensively considers the characteristics of the battery at different temperatures and the charging requirements to achieve safe and efficient charging.

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

[0104] Determining a predicted charging duration based on the charging current;

[0105] When the predicted charging time reaches the target charging time, generating a charging result of successful setting, and feeding back the charging result to the user;

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

[0107] Exemplarily, the predicted charging time can be determined based on the currently determined charging current. This predicted charging time is the time expected to be required to charge the battery to the target power under the current charging current. If the calculated predicted charging time is equal to the target charging time set by the user, it means that the charging setting meets the user's expectations. At this time, a charging result of successful setting is generated, which may include, for example, information such as "Charging setting is successful, charging will be carried out 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 vehicle display screen and mobile phone APP to understand the charging setting.

[0108] If the predicted charging time is less than the target charging time, it means that even if the target charging pile is used to charge with the lowest charging current that can be stably output, the charging time expected by the user cannot be achieved. In this case, the system will feedback the longest charging time, that is, the predicted charging time to the user. This predicted charging time is the longest charging time that can be achieved under the current conditions with the lowest charging current. This predicted charging time is fed back to the user to let the user know the actual charging situation. When the user receives feedback on the longest charging time, there are two options. One is to adjust the target SOC upward, that is, to increase the target power, which can increase the chargeable amount and make the charging time more in line with the demand. The second is to return to the vehicle as soon as possible according to the time recommended by the system. In this way, users can flexibly adjust the charging plan according to actual conditions to better meet their needs.

[0109] like Figure 2 As shown, a charging control system is proposed in this application, and the system 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 being connected to the target charging pile, acquire charging-related parameters, wherein the charging-related parameters include the current power of the target electric vehicle, the target power and the target charging time; acquire the charging billing method, acquire the default charging amount corresponding to the charging billing method, and determine the reference charging amount corresponding to the charging billing method based on the charging-related parameters;

[0111] The calculation module 22 is configured to: when the default charging amount is greater than the deviation value of the reference charging 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 a target power or a target charging time of the target electric vehicle is reached.
