[0032] Some embodiments of the present disclosure will be described in detail here, and examples thereof are shown in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. Various changes, modifications and equivalents of the methods, devices and / or systems described herein will become apparent after understanding the present disclosure. For example, the order of operations described herein is merely an example and is not limited to those orders set forth herein, but can be changed as becomes apparent after understanding the present disclosure, except for operations that must be performed in a specific order. In addition, for clarity and brevity, descriptions of features known in the art may be omitted.

[0033] The embodiments described in some embodiments of the present disclosure below do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0034] Figure 1 is a flow chart of a vehicle charging method according to some embodiments of the present disclosure, such as Figure 1 As shown, the method comprises the following steps:

[0035] S101, determining a target charging type of a battery.

[0036] Optionally, the target charging type of the battery may be an economy priority type and a travel priority type; in other embodiments, the target charging type may include other types, which are not limited herein.

[0037] In some implementations, the economy priority type indicates that the current charging type is a charging type that prioritizes economic affordability, and the travel priority type indicates that the current charging type is a charging type that prioritizes vehicle travel needs.

[0038] S102, determining a target charging time period of the battery and a target charging current of the battery at different SOCs according to the target charging type.

[0039] In some implementations, the state of charge (SOC) reflects the ratio of the remaining dischargeable capacity of the battery to the fully charged state capacity after the battery has been used for a period of time or has not been used for a long time. When the SOC is 0%, it means that the battery is fully discharged, and when the SOC is 100%, it means that the battery is fully charged.

[0040] In some implementations, the target charging time period of the battery is the time the battery is charging. If the target charging type is an economy priority type, the target charging time is a short time period when the electricity price is lower. If the target charging type is a travel priority type, the target charging time period is the time period before travel.

[0041] It is understandable that too fast a charging current may cause the battery temperature to rise, and the increase in battery temperature will cause the battery internal resistance to increase, affecting the battery's safety, temperature and life; the larger the SOC, the more battery power that can be discharged. When the target charging time period is fixed, if the SOC is large, it means that the battery has less power to be charged. In this case, the target charging current can be appropriately reduced to fully charge the battery within the target charging time period while reducing the loss of the battery caused by excessive charging; when the SOC is small, the target charging current can be appropriately increased to ensure that the battery can be fully charged within the target charging time period.

[0042] Optionally, a maximum charging current may be set to constrain the target charging current with the maximum charging current, that is, the target charging current may not exceed the maximum charging current, thereby ensuring charging safety.

[0043] S103, charging the battery within a target charging time period based on the target charging current of the battery at different SOCs.

[0044] It is understandable that after the target charging current of the battery at different SOCs is determined, the battery is charged according to the target charging current within the target charging time period so that the battery power meets the required requirement.

[0045] In this embodiment, the target charging types of the battery are divided, and the target charging time period of the battery is determined according to the requirements emphasized by different target charging types, and the target charging current of the battery at different SOCs is further determined, so that the battery is charged within the target charging time period based on the target charging current, ensuring that the battery charging process is more in line with user expectations and that the battery charging process is safe and reliable, thereby meeting the user's needs in terms of charging economy, travel endurance, and battery reliability.

[0046] Based on the above embodiment, the process of determining the target charging time period is described. Figure 2is a flow chart showing a method of obtaining a target charging time period according to some embodiments of the present disclosure. Figure 2 As shown, the method comprises the following steps:

[0047] S201 , in response to a target charging type being a first charging type, determining a valley time period of electricity price, and determining the valley time period as a target charging time period of the first charging type.

[0048] In some implementations, the first charging type may be an economic priority type, that is, the battery is charged preferentially when the electricity price is favorable.

[0049] It is understandable that the valley price of electricity refers to a lower electricity price implemented during a period of low electricity demand, so the valley price period is also a period of time when lower electricity prices are implemented. Optionally, the target area where the charging pile is located can be determined based on the charging position of the vehicle, the location information or identification information of the charging pile, and the valley price period of the target area can be obtained, that is, the valley price period of the target area can be determined based on the target area where the charging pile is located and the valley price period specified by the target area.

[0050] For example, if the target area defines 10:00 pm to 8:00 am the next day as the valley price period, then the time period from 10:00 pm to 8:00 am the next day is the valley price period.

[0051] When the target charging type is the first charging type, that is, the economic priority type, the valley price time period is used as the target charging time period of the first charging type to reduce economic consumption.

[0052] S202, in response to the target charging type being the second charging type, determining a predicted charging time period and a departure time of the battery, and determining a target charging time period of the second charging type according to the predicted charging time period and the departure time.

[0053] In some implementations, the second charging type may be a travel priority type, that is, battery charging should prioritize meeting the user's travel needs.

[0054] It can be understood that the predicted charging time period of the battery is the time period predicted to be required for the battery to be fully charged, which can be determined based on the charging power of the charging pile and the remaining battery power. For example, the difference between the current remaining battery power and the full battery power is obtained as the battery power to be charged, and the charging power of the charging pile is obtained. The corresponding predicted charging time period is determined based on the charging power and the power to be charged. When the target charging type is the travel priority type, the predicted charging time period and departure time of the battery are determined, and it should be ensured that the battery is fully charged before the user's departure time. Therefore, the target charging time period of the second charging type is obtained based on the predicted charging time period and departure time.

[0055] Optionally, the predicted charging start time and predicted charging end time of the battery can be determined based on the predicted charging time period; in response to the predicted charging end time being earlier than the departure time, the predicted charging time period is determined to be the target charging time period for the second charging type; that is, if the battery can be fully charged before the departure time, the predicted charging time period will be used as the target charging time period for the second charging type.

[0056] In response to the charging end time being later than the departure time, the target charging time period of the second charging type is determined according to the predicted charging start time and the departure time; that is, if the battery cannot be fully charged before the departure time, the time period between the predicted charging start time and the departure time is the target charging time period of the second charging type.

[0057] In this embodiment, the target charging type is divided into a first charging type that prioritizes economy and a second charging type that prioritizes travel. When the target charging type is the first charging type that prioritizes economy, the valley price time period in the charging area is determined as the target charging time period for battery charging to reduce economic cost losses. When the target charging type is the second charging type that prioritizes travel, the predicted charging time period for battery charging is obtained, and the specific target charging time period is determined based on the predicted charging time period and the departure time of the trip to ensure that the user can travel smoothly.

[0058] Based on the above embodiment, the process of obtaining the target charging current of the battery at different SOCs is described. Figure 3 A flow chart of obtaining a target charging current is shown in some embodiments of the present disclosure. Figure 3 As shown, the method comprises the following steps:

[0059] S301, obtaining an effective maximum charging power and charging current mapping curve of a charging pile.

[0060] In this embodiment, the effective maximum charging power is used to reflect the maximum power that the charging pile can provide; wherein the charging power mapping curve includes charging current limits corresponding to different SOCs.

[0061] In some implementations, the maximum first charging power rated by the charging pile can be obtained; the car manufacturer can cooperate with the charging pile or map navigation to open an interconnection mode, and the information of the charging pile can be connected to the vehicle side. When the user navigates to a charging pile in a certain place or inserts a charging pile, the maximum first charging power Pchrgn_max rated by the charging pile can be directly obtained.

[0062] In some implementations, a capability indication message sent by the charging pile can also be received, and the second charging power of the charging pile can be extracted from the capability indication message; in this embodiment, the capability indication message can be a maximum output capability (Charger MaximumLab, CML) message. The CML message is a group of messages in the DC charging message defined by relevant regulations, which is used to inform the maximum output capability of the charging pile. Therefore, the second charging power Pdcchrgn_cml of the charging pile can be determined according to the CML message.

[0063] Furthermore, the minimum charging power between the first charging power and the second charging power can be determined as the effective maximum charging power of the charging pile; that is, the effective maximum charging power Pchrgn=min{Pchrgn_max, Pdcchrgn_cml}, so as to improve the accuracy of obtaining the effective maximum charging current of the charging pile.

[0064] It should be noted that, if the charging pile does not have the second charging power Pdcchrgn_cml given by CML, the rated maximum first charging power Pchrgn_max of the charging pile is the effective maximum charging power of the charging pile.

[0065] In some implementations, the charging current mapping curve may be charging current limits at different SOCs at different ambient temperatures defined by a battery supplier based on battery reliability and charging speed, and thus the corresponding charging current mapping curve may be determined based on battery information.

[0066] For example, in the charging current mapping curve, the charging current limit value in the low SOC and high SOC stages can be lower, and the charging current limit value in the low temperature condition is lower, so as to protect the capacity of the battery cell; the charging current limit value is higher at normal temperature and the intermediate SOC stage, so as to achieve the purpose of fast charging and improve the user experience; Figure 4 As shown, it is a schematic diagram of a charging current mapping curve provided in this embodiment. In the low SOC and high SOC stages, every 1% SOC change will correspond to a change in the charging current limit. In the middle SOC stage, the charging current limit is high and stable.

[0067] S302, determining a reference charging current of the battery at different SOCs according to an effective maximum charging power and a charging current mapping curve.

[0068] In some implementations, the maximum charging voltage calibrated by the battery can be obtained, and the maximum charging current of the charging pile can be determined based on the effective maximum charging power and the maximum charging voltage; optionally, the ratio of the effective maximum charging power Pchrgn of the charging pile to the maximum charging voltage calibrated by the battery can be calculated as the maximum charging current of the charging pile.

[0069] Furthermore, for each SOC, the charging current limit corresponding to the SOC is determined according to the charging current mapping curve, and the minimum value is determined from the maximum charging current and the charging current limit as the reference charging current corresponding to the SOC to ensure charging according to the safe maximum charging current to meet user needs.

[0070] For example, Figure 4 As shown, in this embodiment, each SOC refers to every 1% of the SOC. The charging current limit of each SOC is determined according to the charging current mapping curve, and the minimum value between the charging current limit corresponding to the SOC and the maximum charging current is determined as the reference charging current corresponding to the SOC.

[0071] S303, determining a target charging current of the battery at different SOCs according to a reference charging current and a target charging type of the battery at different SOCs.

[0072] In some implementations, in response to the target charging type being the first charging type, a reference charging current of the battery at different SOCs is determined as the target charging current of the battery at different SOCs; that is, when the target charging type is the economy priority type, the reference charging current of the battery at different SOCs is used as the target charging current of the battery at different SOCs.

[0073] In some implementations, in response to the target charging type being the second charging type, a predicted charging time period and a departure time of the battery are determined, wherein the predicted charging time period includes a predicted charging start time and a predicted charging end time of the battery, and a target charging current of the battery at different SOCs is determined based on the predicted charging time period and the departure time of the battery.

[0074] In some implementations, the cell type of the battery may be determined, and the target SOC of the battery may be determined based on the cell type. Optionally, the cell type may include a lithium iron phosphate battery and a ternary lithium battery; if the cell type of the battery is a lithium iron phosphate battery, the target SOC may be set to 100%; if the cell type of the battery is a ternary lithium battery, the target SOC may be set to 80%.

[0075] In response to the battery cell type being a specified cell type and the configured target SOC being greater than the set SOC, the target SOC is reduced to the set SOC. In this embodiment, the specified cell type is a ternary lithium battery, that is, when the user-configured target SOC is greater than 80% of the set target SOC, the user-configured target SOC is reduced to 80% to avoid the battery being in a "deep charge and deep discharge" state for a long time.

[0076] Furthermore, the SOC increment interval sequence between the current remaining SOC of the battery and the target SOC can be determined; the predicted charging time of the battery can be determined based on the SOC increment interval sequence and the charging current mapping curve; and the predicted charging time period can be determined based on the predicted charging time. Optionally, the SOC change can be determined based on the remaining SOC and the target SOC; starting from the remaining SOC, the SOC change can be divided according to the set step size to obtain multiple SOC increment intervals; based on the multiple SOC increment intervals, the SOC increment interval sequence can be obtained.

[0077] In some implementations, the battery's full-charge range and energy consumption per unit distance can also be obtained, and the electric energy required for the battery to reach the target SOC can be determined based on the SOC change, full-charge range and energy consumption per unit distance; optionally, the electric energy required for the battery to reach the target SOC can be calculated as: Δkwh=ΔSOC*full-charge range*average energy consumption per 100 kilometers / 100; where Δkwh is the electric energy required for the battery to reach the target SOC, ΔSOC is the SOC change, and the average energy consumption per 100 kilometers / 100 is the energy consumption per unit distance.

[0078] For each SOC increment interval in the SOC increment interval sequence, the charging current limit of the SOC increment interval is determined according to the charging current mapping curve; the charging time corresponding to the SOC increment interval is determined according to the charging current limit of the SOC increment interval; and the predicted charging time is determined according to the charging time corresponding to each SOC increment interval.

[0079] For example, Figure 4 The charging current mapping curve shown in the figure, where SOC_init is the current remaining SOC, SOC_Target is the target SOC, and the portion between SOC_init and SOC_Target is the SOC change; starting from the remaining SOC_init, the SOC change is divided according to the set step length to obtain multiple SOC increment intervals. In this embodiment, the step length is set to 1% SOC, that is, the SOC change is divided into multiple SOC increment intervals according to the step length of 1%, thereby obtaining a SOC increment interval sequence; further according to Figure 4 Determine the charging current limit for each SOC increment interval, calculate the charging time corresponding to the SOC increment interval based on the charging current limit, and then determine the predicted charging time.

[0080] Optionally, the calibrated full charge of the battery can be determined; the charging time corresponding to the SOC increment interval is determined according to the set step size, the charging current limit and the full charge; the charging time corresponding to the SOC increment interval can be calculated as: 1%*A*H=Ik*tk; wherein A*H is the calibrated full charge of the battery, 1% is the set step size of this embodiment, Ik is the charging current limit value of the SOC increment interval, and tk is the charging time corresponding to the SOC increment interval.

[0081] Furthermore, the sum of the charging times corresponding to all SOC increment intervals is obtained as the predicted charging time; the target charging current of the battery at different SOCs is determined according to the predicted charging time period and the departure time of the battery, wherein the predicted charging time period includes the predicted charging start time and the predicted charging end time of the battery.

[0082] In some implementations, if the predicted charging end time is later than or equal to the departure time, the reference charging current of the battery at different SOCs is determined as the target charging current of the battery at different SOCs; that is, if the predicted charging end time cannot meet the power requirement at the departure time, the charging current cannot be reduced, and the target charging current of the battery at different SOCs is determined as the corresponding reference charging current.

[0083] In some implementations, if the predicted charging end time is earlier than the departure time, the reference charging current of the battery at different SOCs is reduced to obtain the target charging current of the battery at different SOCs; that is, the charging of the battery can be completed before the departure time to meet the power requirement at the departure time. The reference charging current of the battery at different SOCs can be adaptively reduced to reduce the impact of excessive charging power on battery safety and life, and to extend the charging time by reducing the charging current, thereby improving the reliability of the battery.

[0084] Optionally, the interval between the departure time and the current time can be obtained; the ratio of the predicted charging time and the interval time can be obtained as an adjustment coefficient; for each SOC, the reference charging current under the SOC is reduced according to the adjustment coefficient to obtain the target charging current under the SOC. For example, if the predicted charging time is T1 and the interval between the departure time and the current time is T2, the adjustment coefficient is T1 / T2, and the reference charging current of each SOC is reduced based on the adjustment coefficient to obtain the target charging current under the SOC.

[0085] In this embodiment, the effective maximum charging power of the charging pile is obtained by the rated first charging power of the charging pile and the second charging power determined by the CML message, and the reference charging current of the battery at different SOCs is determined according to the effective maximum charging power and the charging current mapping curve to ensure that the user's charging needs can be met; according to the reference charging current and the target charging type under different SOCs, the target charging current when economy is prioritized and the target charging current when travel is prioritized are determined, and in the process of obtaining the target charging current, the target SOC is determined according to the cell type, the SOC change is determined according to the current remaining SOC and the target SOC, and the predicted charging time is further determined based on the SOC change. According to the relationship between the predicted charging end time and the departure time of the predicted charging time, the target charging current is adaptively acquired, and the two situations of economy priority and travel priority are combined. When the user does not have an urgent need to travel, the charging current is reduced to improve the stability of the battery and reduce the loss of battery life, so as to ensure the maximum safe charging of the battery while meeting the user's needs.

Therefore, the following detailed description should not be considered in a limiting sense.

[0175] It should be understood that, unless otherwise specifically noted, the features of some embodiments of the various present disclosures described herein may be combined with each other.

However, the term "above" used in relation to a component, element or material layer formed "above" or located "above" a surface may also optionally have a specific meaning: the component, element or material layer is "directly" positioned (e.g., placed, formed, deposited, etc.) on the surface, such as in direct contact with the surface.

For example, if the device in the drawings is turned over, the element described as being "above" or "upper" relative to another element will be "below" or "lower" relative to the other element. Therefore, depending on the spatial orientation of the device, the term "above" includes both upper and lower orientations. The device may have other orientations (e.g., rotated 90 degrees or in other orientations), and the spatially relative terms used herein should be interpreted accordingly.
