[0046] Although the present application can be easily embodied in different forms of embodiments, only some of the specific embodiments are shown in the drawings and will be described in detail in this specification. It should be understood that this description should be regarded as an exemplary illustration of the principles of the application and is not intended to limit the application to what is described herein.

[0047] Furthermore, the terms "comprises," "includes," "has," and any variations thereof mentioned in the description of this application are intended to cover non-exclusive inclusions. For example, a process, method, system, product, or apparatus comprising a series of steps or modules is not limited to the listed steps or modules, but may optionally include other steps or modules not listed, or may optionally include other steps or modules inherent to the process, method, product, or apparatus.

[0048] It should be noted that, in the embodiments of the present application, words such as "exemplary," "for example," or "for example" are used to indicate examples, illustrations, or descriptions. Any embodiment or design described in the embodiments of the present application as "exemplary," "for example," or "for example" should not be interpreted as being preferred or advantageous over other embodiments or designs. Rather, the use of words such as "exemplary," "for example," or "for example" is intended to present the relevant concepts in a concrete manner.

[0049] The exemplary embodiments will be described in detail below. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. Instead, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the Summary of the Invention.

[0050] As described in the background technology, for vehicles equipped with a scheduled charging function, charging is no longer limited to starting charging when the vehicle charging gun is detected to be inserted into the charging pile and stopping charging when the vehicle battery is fully charged. Instead, the user can set the charging start time, charging end time, etc. based on vehicle usage needs, and can even set the battery level when charging is completed, rather than just stopping charging when the vehicle battery is fully charged. Because the duration corresponding to the user's scheduled charging start and end times may exceed the actual charging duration required, the vehicle can be charged during the time period corresponding to the user's scheduled charging start and end times based on the time-of-use electricity price in the vehicle's geographical area.

[0051] The vehicle may be a pure electric vehicle using electricity as the sole power source, or a hybrid vehicle using electricity as one of the power sources and other energy sources as the power source, or other vehicles that can be charged externally.

[0052] In the vehicle battery charging method of the embodiment of the present application, when the user sets the charging end time, if the total time corresponding to the start time when the charging start condition is met to the charging end time set by the user is greater than the charging time required for the battery power to reach the target power, for each time period within the time interval from the start time when the charging start condition is met to the charging end time set by the user, first sort the time periods according to the electricity price of each time period, and then select several time periods corresponding to the electricity price sorted from low to high as the charging time, and then send a charging request signal based on the determined charging time, so that the charging pile performs the charging operation on the vehicle battery, thereby achieving the goal of meeting the user's charging needs while maximizing the charging cost savings for the user.

[0053] In an exemplary embodiment, Figure 1 As shown, the vehicle battery charging method of the present application includes a charging demand information acquisition step, a required charging time calculation step, a charging time determination step, and a charging control step, which correspond to the following steps S101, S102, S103 to S105, and S106 respectively.

[0054] S101, receiving charging requirement information set by a user.

[0055] In some exemplary embodiments, the charging demand information includes a charging end time. In some exemplary embodiments, the charging demand information includes a charging end time and a charging start time. In some exemplary embodiments, the charging demand information includes not only the charging end time and the charging start time but also a target power level. In some exemplary embodiments, the charging demand information may also include the charging end time and the target power level.

[0056] S102, obtaining the remaining power of the vehicle battery, and obtaining the charging time required to reach the target power according to the remaining power and charging pile parameters.

[0057] The target power level can be a fully charged battery level or any power level set by the user. It is understood that if the target power level is any power level set by the user, it is greater than the remaining power of the vehicle battery. If the charging requirement information set by the user does not include a target power level, the fully charged battery level is directly used as the target power level.

[0058] Specifically, the charging pile parameter can be the charging pile power. The required charging time is calculated by calculating the difference between the target power level and the remaining power level of the vehicle battery, and then using this power difference and the charging pile power to calculate the required charging time. In some embodiments, the ambient temperature of the vehicle can also be considered, with the impact of ambient temperature on charging speed being an influencing factor in the calculation of the required charging time.

[0059] S103, calculating the total duration from the start time when the charging start condition is met to the charging end time.

[0060] In embodiments where the charging requirement information includes both the charging end time and the charging start time, the starting time for satisfying the charging start condition is when the charging start time has been reached and the vehicle charging gun has been detected to be plugged into the charging station. In embodiments where the charging requirement information only includes the charging end time, the starting time for satisfying the charging start condition is when the vehicle charging gun is detected to be plugged into the charging station.

[0061] S104, compare the total time and the charging time. If the total time is greater than the charging time, go to step S105a, and then go to step S106; otherwise, if the total time is less than or equal to the charging time, go to step S105b, and then go to step S106.

[0062] S105a, obtaining the electricity prices corresponding to the various time periods within the time interval from the start time to the end time of charging in the geographical area where the vehicle is located, sorting the various time periods according to the electricity prices, and selecting several time periods corresponding to the electricity prices sorted from low to high as charging times.

[0063] The sum of the durations of the multiple time periods is equal to the charging duration. It can be understood that the multiple time periods corresponding to the order of electricity prices from low to high refer to the multiple time periods with lower electricity prices among the various time periods within the time interval from the start time to the end time of charging.

[0064] For example, the starting time when the charging start condition is met to the charging end time set by the user is 21:00-04:00, and the "peak and valley time-of-use electricity price" in the geographical area where the vehicle is located is divided into: [00:00,05:00], [05:00,08:00], [08:00,11:00], [11:00,14:00], [14:00,18:00], [18:00, There are seven time periods in total: [00:00,05:00]<[05:00,08:00]<[22:00,24:00]<[08:00,11:00]<[14:00,18:00]<[11:00,14:00]<[18:00,22:00]. Assume that the vehicle battery is fully charged with 50kWh, the target power is the fully charged power of the battery, the maximum power of the charging pile is 7kw, and the current remaining power of the vehicle battery is 30%. According to the power of the charging pile, the charging time required to fully charge the vehicle battery is about 6 hours. It can be seen that the required charging time is less than the time from the start time when the charging start conditions are met to the charging end time set by the user (7 hours). The time-of-use electricity price periods corresponding to 21:00-04:00 are [21:00,22:00], [22:00,24:00] and [00:00,04:00]. The periods with the lowest electricity prices between 21:00-04:00 are [22:00,24:00] and [00:00,04:00]. Therefore, the periods [22:00,24:00] and [00:00,04:00] are selected as the charging time, and charging starts at 22:00 and ends at 04:00.

[0065] For example, the starting time when the charging start condition is met to the charging end time set by the user is 09:00-18:00, and the "peak and valley time-of-use electricity price" of the vehicle's geographical area is divided into: [00:00,05:00], [05:00,08:00], [08:00,11:00], [11:00,14:00], [14:00,18:00], [18:00 ,22:00],[22:00,24:00], there are seven time periods in total. These seven time periods are sorted from low to high according to the electricity price as follows: [00:00,05:00]<[05:00,08:00]<[22:00,24:00]<[08:00,11:00]<[14:00,18:00]<[11:00,14:00]<[18:00,22:00]. Assume that the vehicle battery is fully charged at 50kWh, the target power is the fully charged power, the maximum power of the charging pile is 7kw, and the current remaining power of the vehicle battery is 15%. Based on the power of the charging pile, the charging time required to fully charge the vehicle battery is about 7 hours. Therefore, it can be seen that the required charging time is less than the time from the start time when the charging start conditions are met to the charging end time set by the user (9 hours). The time-of-use electricity price period corresponding to 09:00-18:00 is [09:00,11:00]. , [11:00,14:00] and [14:00,18:00]. Among them, the electricity price at [09:00,11:00] is the lowest and the electricity price at [11:00,14:00] is the highest. Therefore, [09:00,11:00], [11:00,12:00] and [14:00,18:00] are selected as the charging time. Charging starts at 9:00, pauses at 12:00, and resumes at 14:00 until charging stops at 18:00.

[0066] S105b: The period between the start time when the charging start condition is met and the charging end time set by the user is used as the charging time.

[0067] S106: Send a charging request signal based on the charging time to control the charging pile to perform a charging operation on the vehicle battery.

[0068] In detail, in an exemplary embodiment, step S106 includes the following steps S1061 to S1063.

[0069] S1061 , sorting the various time periods included in the charging time according to the morning and evening of the natural day.

[0070] S1062, determine whether the charging time spans a natural day. If the charging time is on the same natural day, proceed to step S1063a; if the charging time spans a natural day, proceed to step S1063b.

[0071] S1063a, sending a charging request signal in the order of morning and evening in each time period to control the charging pile to perform a charging operation on the vehicle battery.

[0072] S1063b: Send a charging request signal according to the time closest to the start time that meets the charging start condition among the several time periods included in the charging time, and control the charging pile to perform a charging operation on the vehicle battery.

[0073] It can be understood that in an embodiment where there is information interaction between the vehicle and the charging pile, the charging request signal can be sent to the charging pile, and after receiving the charging request signal, the charging pile outputs power supply to charge the vehicle battery; and in an embodiment where there is no information interaction between the vehicle and the charging pile, the charging circuit of the vehicle battery can be provided with a charging trigger switch, and the charging request signal is sent to the charging trigger switch to turn on the charging trigger switch, thereby enabling the charging pile to output power supply to charge the vehicle battery.

[0074] See Figure 2 As shown, in Figure 2 In the exemplary embodiment shown, the charging method of the present application first executes the charging time recommendation step before executing the charging demand information acquisition step, and first executes the required charging time and power related information feedback step before executing the charging time determination step, and after executing the charging control step, also executes the cost saving information feedback step.

[0075] exist Figure 2 In the illustrated embodiment, the vehicle battery charging method of the present application includes a charging time recommendation step, a charging demand information acquisition step, a required charging time and power-related information calculation step, a required charging time and power-related information feedback step, a charging time determination step, a charging control step, and a cost-saving information feedback step, which correspond to steps S201 to S202, step S203, step S204, step S205, steps S206 to S207, step S208, and step S209, respectively.

[0076] S201, obtaining electricity price information of the geographical area where the vehicle is located.

[0077] The electricity price information includes the time periods divided into time-of-use electricity prices and the electricity prices corresponding to each period.

[0078] S202: Send several time periods with lower electricity prices to the user as optimal charging times.

[0079] Specifically, after obtaining the electricity prices corresponding to each time period, the time periods can be sorted according to the electricity prices, and several time periods with the lowest electricity prices are selected as the optimal charging times and sent to the user.

[0080] By sending several time periods with the lowest electricity prices as the optimal charging time to users, the user's interactive experience is enhanced, and the convenience and other car-using experiences are improved. At the same time, users can set charging demand information based on the received optimal charging time to save charging costs. Of course, users can also set charging demand information based on their own travel needs and not according to the optimal charging time.

[0081] S203: Receive charging requirement information set by the user.

[0082] In detail, the charging demand information includes a charging end time tu2 and a charging start time tu1 , that is, the charging period desired by the user is [tu1 , tu2 ].

[0083] In this exemplary embodiment, the charging start time tu1 is later than the time when the vehicle charging gun is detected to be inserted into the charging pile. Therefore, the charging start time tu1 set by the user is the starting time for satisfying the charging start condition.

[0084] S204, obtaining the remaining power of the vehicle battery, and obtaining the charging time required to fully charge the battery and the battery power information when charging is completed when the vehicle battery is charged based on the charging demand information according to the remaining power and the charging pile parameters.

[0085] For example, the battery power related information may be the battery power, the battery power related information may also be the battery driving range corresponding to the battery power, or the battery power related information may also include the battery power and the battery driving range corresponding to the battery power.

[0086] S205: Send the battery power information and charging time to the user.

[0087] By sending battery power information and charging time to users, the user's interactive experience is enhanced, and the user's car-using convenience and other car-using experiences are improved.

[0088] In detail, in an exemplary embodiment, the battery charge-related information includes the battery charge and the battery range corresponding to the battery charge. When the battery charge is sent to the user, the battery range corresponding to the battery charge is also sent to the user. The user can intuitively obtain the pure electric range after charging is completed based on the charging demand information set by the user, so as to further determine whether to modify the charging demand information set by the user based on the actual vehicle use needs.

[0089] More specifically, by acquiring historical power consumption data of the vehicle in a geographical area, the battery range is calculated based on the historical power consumption data and the battery power when charging is completed when a charging operation is performed on the vehicle battery based on the charging demand information.

[0090] S206, compare the total time corresponding to the charging start time to the charging end time with the required charging time. If the total time is greater than the charging time, go to step S207a, and then go to step S208; conversely, if the total time is less than or equal to the charging time, go to step S207b, and then go to step S208.

[0091] S207a, obtaining the electricity prices corresponding to the various time periods within [tu1, tu2] in the geographical area where the vehicle is located, sorting the time periods according to the electricity prices, and selecting several time periods corresponding to the electricity prices sorted from low to high as charging time.

[0092] The total duration of several time periods is equal to the charging time.

[0093] S207b, take [tu1, tu2] as the charging time.

[0094] S208: Send a charging request signal based on the charging time to control the charging pile to perform a charging operation on the vehicle battery.

[0095] It is understood that before step S208, if the user's charging requirement modification information is received, the charging requirement information is updated to the charging requirement modification information, and step S206 is re-executed based on the updated charging requirement information, that is, the process returns to step S206. In some embodiments, if the user's charging requirement modification information is received, the process directly returns to step S204.

[0096] S209, calculate the difference between the charging cost consumed by sending a charging request signal based on the charging time, controlling the charging pile to perform a charging operation on the vehicle battery, and the charging cost required to directly perform a charging operation on the vehicle battery according to the start time and the charging end time that meet the charging start conditions, obtain the charging cost saving information, and send the charging cost saving information to the user.

[0097] By sending charging cost saving information to users, the user's interactive experience is enhanced, and the user's car-using convenience and other car-using experiences are improved.

[0098] It can be understood that in some embodiments, the cost saving information feedback step can be performed after the charging time determination step and before the charging control step, or the charging cost saving information can be calculated and sent to the user during the execution of the charging control step.

[0099] Understandably, in Figure 2In the illustrated embodiment, in steps S202, S205, and S209, corresponding information may be sent to the user's electronic device or vehicle terminal. The user's electronic device may be, for example, a mobile phone, IPAD, or other device with information interaction function. Similarly, the user may set charging demand information on his or her electronic device or vehicle terminal.

[0100] It can be understood that in some embodiments, for the steps of charging time recommendation step, power-related information feedback step, and cost-saving information feedback step, one or more of them can be selectively executed, and is not limited to executing all of the charging time recommendation step, power-related information feedback step, and cost-saving information feedback step.

[0101] See next Figure 3 , Figure 3 This is a flow chart of a vehicle battery charging method according to an exemplary embodiment of the present application. Figure 3 In the illustrated embodiment, the following steps S301 to S309 are included.

[0102] S301, obtaining the electricity price division time periods [t1, t2], [t2, t3], [t3, t4], ..., [tn-1, tn], [tn, tn+1] of the geographical area where the vehicle is located and the electricity price of each time period.

[0103] S302, receiving the charging time period [tu1, tu2] set by the user.

[0104] Wherein, tu1 represents the charging start time and tu2 represents the charging end time. The charging start time tu1 is later than the time when the vehicle charging gun is detected to be inserted into the charging pile.

[0105] S303, calculating the charging time Tf required for full charging.

[0106] The charging time Tf required for full charge is less than the time corresponding to the charging period [tu1, tu2] set by the user.

[0107] S304, determine whether [tu1, tu2] fall in the same electricity price period. If [tu1, tu2] fall in the same electricity price period, go to step S305a; otherwise, if [tu1, tu2] do not fall in the same electricity price period, go to step S305b.

[0108] S305a, directly start charging according to the charging start time tu1 set by the user until the vehicle battery is fully charged.

[0109] S305b, obtaining all electricity price periods spanned by the charging period [tu1, tu2] set by the user, and sorting them from low to high according to the electricity price of each period into T1, T2, T3...Tp.

[0117] Next, taking two specific embodiments as examples, the vehicle battery charging method of the present application will be further elaborated in detail.

[0118] A specific embodiment:

[0119] As Figure 4 shown, in this exemplary embodiment, the vehicle battery charging method includes the following steps S401 to step S408.

[0120] S401, obtaining the electricity price division time periods of the vehicle's geographical area, which specifically include seven time periods: [00:00, 05:00], [05:00, 08:00], [08:00, 11:00], [11:00, 14:00], [14:00, 18:00], [18:00, 22:00], [22:00, 24:00]. These seven time periods are sorted from low to high according to electricity price as follows: [00:00, 05:00] < [05:00, 08:00] < [22:00, 24:00] < [08:00, 11:00] < [14:00, 18:00] < [11:00, 14:00] < [18:00, 22:00].

[0121] S402, receiving the charging time period set by the user, specifically [21:00, 04:00].

[0122] In step S403, the charging time Tf required to fully charge the battery is calculated based on the remaining battery charge of the vehicle and the charging station power, which is 6 hours. At this point, it is known that the charging time corresponding to the user-set charging period [21:00, 04:00] (7 hours) is greater than the charging time required to fully charge the battery (6 hours).

[0123] S404 , calculating and obtaining whether the charging time period [21:00, 04:00] set by the user falls within the three time periods [18:00, 22:00], [22:00, 24:00], and [00:00, 05:00].

[0124] In step S405, the three time periods are sorted as [00:00, 05:00] < [22:00, 24:00] < [18:00, 22:00] according to the electricity price from low to high. The corresponding durations of these three time periods falling within the charging period [21:00, 04:00] are 4 hours, 2 hours, and 1 hour, respectively. For ease of description, they are expressed as T1 = 4 hours, T2 = 2 hours, and T3 = 1 hour, respectively.

[0125] In step S406, according to T1+T2+T3...+Tm>=Tf, Tf=6 hours, it can be determined that m=2, that is, T1+T2=6 hours>=Tf, so the charging time can be determined as [22:00, 24:00], [00:00, 04:00].

[0126] S407 , obtaining a time period sequence M according to the natural time sequence of the time periods corresponding to the T1 and T2 electricity price time periods. The time period sequence M is calculated as [00:00, 04:00], [22:00, 24:00].

[0127] S408 , charging starts from the time period [22:00, 24:00] that is closest to the time point tu1=21:00 in the time period sequence M. The charging execution time period sequence is [22:00, 24:00], [00:00, 04:00].

[0128] A specific embodiment:

[0129] like Figure 5 As shown, in this exemplary embodiment, the vehicle battery charging method includes the following steps S501 to S508.

[0130] S501, obtaining the electricity price division time periods of the vehicle's geographical area, which specifically include seven time periods: [00:00, 05:00], [05:00, 08:00], [08:00, 11:00], [11:00, 14:00], [14:00, 18:00], [18:00, 22:00], [22:00, 24:00]. These seven time periods are sorted from low to high according to electricity price as follows: [00:00, 05:00] < [05:00, 08:00] < [22:00, 24:00] < [08:00, 11:00] < [14:00, 18:00] < [11:00, 14:00] < [18:00, 22:00].

[0131] S502: Receive the charging time period set by the user, specifically [09:00, 18:00].

[0132] In step S503, the charging time Tf required to fully charge the battery is calculated based on the remaining battery charge of the vehicle and the charging station power, which is 7 hours. At this point, it is known that the charging time period [09:00, 18:00] set by the user (9 hours) corresponds to a longer charging time than the required 7 hours to fully charge the battery.

[0133] S504 , calculating and obtaining whether the charging time period [09:00, 18:00] set by the user falls within the three time periods [08:00, 11:00], [11:00, 14:00], and [14:00, 18:00].

[0134] In step S505, the three time periods are sorted from low to high according to the electricity price as [08:00, 11:00] < [14:00, 18:00] < [11:00, 14:00]. The corresponding durations of these three time periods falling within the charging period [09:00, 18:00] are 2 hours, 4 hours, and 3 hours, respectively. For ease of description, they are expressed as T1 = 2 hours, T2 = 4 hours, and T3 = 3 hours, respectively.

[0135] In step S506, based on T1+T2+T3…+Tm>=Tf, and Tf=7 hours, it can be determined that m=3, that is, T1+T2+T3=9 hours>=Tf, so the charging time can be determined as [09:00,11:00], [14:00,18:00], [11:00,12:00].

[0136] S507 , obtaining a time period sequence M according to the natural time sequence of the time periods corresponding to the T1 , T2 , and T3 electricity price periods. The time period sequence M is calculated as [09:00, 11:00], [11:00, 12:00], [14:00, 18:00].

[0137] S508: Charging starts from the closest time period [09:00, 11:00] after tu1 = 09:00 in the time period sequence M. The charging execution time period sequence is [09:00, 11:00], [11:00, 12:00], [14:00, 18:00]. Charging starts at 9:00, pauses at 12:00, resumes at 14:00, and ends at 18:00.
