[0002] With the development of electric vehicles, the demand for charging facilities has grown rapidly. Existing charging piles usually have multiple external charging terminals to charge multiple electric vehicles at the same time. The power source of the multiple charging terminals is the multiple power units in the charging pile. In order to meet the charging needs of multiple charging terminals, it is necessary to allocate multiple power units to multiple charging terminals for power supply.

However, the charging requirements are different when the charging terminal is connected to different devices to be charged. The power unit allocation method that binds the power unit to the charging terminal one-to-one makes the output of the power unit often mismatch the charging demand.

The target charging terminal is the charging terminal connected to the target device. The priority information is used to indicate the power supply priority of the target charging terminal among multiple charging terminals of the charging pile. The target charging terminal belongs to multiple charging terminals. Terminal 02 allocates a power unit for power supply to the target charging terminal from multiple power units in the charging pile based on the priority information.

[0029] In addition, it should be noted that Figure 1 What is shown is only one application environment provided by the present disclosure. In actual application, other application environments may also be included.

[0030] In the embodiments of this specification, the server 01 and the terminal 02 may be directly or indirectly connected via wired or wireless communication, which is not limited in this disclosure.

[0031] Figure 2 is a flow chart of a power unit allocation method according to an exemplary embodiment. Figure 2 As shown, the power unit allocation method includes the following: Step S201: Obtain battery power information, battery temperature status information, battery voltage status information and power requirement information corresponding to the target device.

[0032] In the disclosed embodiment, the target device may be a vehicle powered by a battery, such as an electric car, an electric bicycle, etc., wherein the electric car may be an electric car for different purposes, such as a car, a bus, a truck, etc., and the battery capacity and power requirements of different target devices are different. In the disclosed embodiment, the object for acquiring the battery power information, the battery temperature status information, the battery voltage status information, and the power requirement information may be a charging pile connected to the target device, or a controller or server that allocates power units to the charging pile.

[0033] In an optional embodiment, the process of obtaining the battery power information includes: after the target device establishes a connection relationship with the charging pile, accessing the battery power storage unit in the battery management system of the target device to obtain the current battery power information (State of Charge, SOC) corresponding to the target device. The battery power information is usually expressed in the form of a percentage, such as 20%, 60%.

[0034] In an optional embodiment, the process of acquiring the battery temperature status information includes: Obtain a battery temperature value of a target device; when the battery temperature value is within a preset battery temperature range, determine a first preset constant as a normalized battery temperature value corresponding to the target device; when the battery temperature value is not within the preset battery temperature range and the absolute value of the difference between the battery temperature value and an upper limit value or a lower limit value of the preset battery temperature range is less than or equal to the preset temperature difference, determine a second preset constant as the normalized battery temperature value corresponding to the target device, and the second preset constant is less than the first preset constant; when the battery temperature value is not within the preset battery temperature range and the absolute value of the difference between the battery temperature value and an upper limit value or a lower limit value of the preset battery temperature range is greater than the preset temperature difference, determine a third preset constant as the normalized battery temperature value corresponding to the target device, and the third preset constant is less than the second preset constant; determine the normalized battery temperature value as the battery temperature status information.

[0035] In the embodiment of the present disclosure, the battery temperature value of the target device can be obtained by accessing the battery temperature storage unit in the battery management system of the target device after the target device establishes a connection relationship with the charging pile to obtain the current battery temperature value corresponding to the target device. The battery temperature value can be collected by a temperature sensor and stored in the battery temperature storage unit.

[0036] The preset battery temperature interval can be determined according to the optimal operating temperature range corresponding to the battery. For example, when the optimal operating temperature range corresponding to the battery is 20°~40°, the preset battery temperature interval can be [20,40]. The first preset constant can be set to 1. When the battery temperature value is within the preset battery temperature interval, the constant 1 is determined as the battery temperature normalization value corresponding to the target device, and the constant 1 is determined as the battery temperature state information.

[0037] The preset temperature difference is recorded as Δt, and the temperature range that is not in the preset battery temperature interval and the absolute value of the difference with the upper limit or lower limit of the preset battery temperature interval is less than or equal to the preset temperature difference is [20-Δt, 20) ∪ (40, 40 + Δt]. The present disclosure does not limit the value of the preset temperature difference. For example, if the preset temperature difference is 15°, the temperature range that is not in the preset battery temperature interval and the absolute value of the difference with the upper limit or lower limit of the preset battery temperature interval is less than or equal to the preset temperature difference is [5, 20) ∪ (40, 55). The second preset constant can be set to 0.5. When the battery temperature value is not in the preset battery temperature interval and the absolute value of the difference with the upper limit or lower limit of the preset battery temperature interval is less than or equal to the preset temperature difference, the constant 0.5 is determined as the battery temperature normalization value corresponding to the target device, and the constant 0.5 is determined as the battery temperature state information.

[0038] The temperature range that is not in the preset battery temperature interval and the absolute value of the difference with the upper limit or lower limit of the preset battery temperature interval is greater than the preset temperature difference is less than 20-Δt°, or greater than 40+Δt°. The present disclosure does not limit the value of the preset temperature difference. For example, if the preset temperature difference is 15°, the temperature range that is not in the preset battery temperature interval and the absolute value of the difference with the upper limit or lower limit of the preset battery temperature interval is greater than the preset temperature difference is less than 5°, or greater than 55°. The second preset constant can be set to 0.2. When the battery temperature value is not in the preset battery temperature interval and the absolute value of the difference with the upper limit or lower limit of the preset battery temperature interval is greater than the preset temperature difference, the constant 0.2 is determined as the battery temperature normalization value corresponding to the target device.

[0039] Based on the above, it can be known that in the embodiment of the present disclosure, the corresponding preset constant is determined as the battery temperature status information according to the temperature range of the battery temperature value of the target device. The preset constant can reflect the battery temperature status of the current target device to obtain normalized battery temperature status information.

[0040] In an optional embodiment, the process of acquiring the battery voltage status information includes: Obtain the current highest single cell voltage of the target device and the highest single cell voltage configured for the target device; determine the ratio of the current highest single cell voltage to the highest single cell voltage as the target voltage ratio; and determine the difference between the fourth preset constant and the target voltage ratio as the battery voltage status information.

[0041] In the embodiment of the present disclosure, a method for obtaining the current highest single-cell voltage of the target device and the highest single-cell voltage configured for the target device can be, after the target device establishes a connection relationship with the charging pile, accessing the voltage management unit in the battery management system of the target device to obtain the current highest single-cell voltage of the target device and the highest single-cell voltage configured for the target device, wherein the current highest single-cell voltage can be collected by a voltage sensor and stored in the voltage management unit.

[0042] The above process of determining the ratio of the current highest single cell voltage to the highest single cell voltage as the target voltage ratio and determining the difference between the fourth preset constant and the target voltage ratio as the battery voltage status information can be calculated by the following formula (1): (1) In formula (1), is the battery voltage status information, constant 1 is the fourth preset constant, is the current highest single cell voltage, The maximum single cell voltage.

[0043] Based on the above, it can be known that in the embodiment of the present disclosure, by determining the ratio of the current highest single cell voltage to the highest single cell battery voltage as the target voltage ratio, and determining the difference between the fourth preset constant and the target voltage ratio as the battery voltage status information, the quantized battery voltage status information can be obtained through the above calculation.

[0044] In an optional embodiment, the process of acquiring the power demand information includes: Obtain the required voltage value and required current value corresponding to the target device; multiply the required voltage value and the required current value to obtain power demand information.

[0045] In the embodiment of the present disclosure, the method for obtaining the required voltage value and the required current value corresponding to the target device can be to access the voltage management unit and the current management unit in the battery management system of the target device respectively after the target device establishes a connection relationship with the charging pile, so as to obtain the required voltage value and the required current value corresponding to the target device.

[0046] The above process of multiplying the required voltage value and the required current value to obtain the power demand information can be calculated by the following formula (2): (2) In formula (2), is the power demand information, is the required voltage value, is the required current value.

[0047] Step S202: Based on the battery power information, battery temperature status information, battery voltage status information and power demand information, the target charging terminal is prioritized to obtain the priority information corresponding to the target charging terminal. The target charging terminal is the charging terminal to which the target device is connected. The priority information is used to indicate the power supply priority of the target charging terminal among the multiple charging terminals of the charging pile. The target charging terminal belongs to multiple charging terminals.

[0048] In the embodiment of the present disclosure, the charging terminal is a charging gun configured for the charging pile, and the target charging terminal establishes a connection with the target device and confirms the connection relationship, which may be that the target charging terminal is connected to the charging port of the target device and forms a passage.

[0049] Figure 3 This is a flowchart of a priority configuration according to an exemplary embodiment. In an optional embodiment, priority configuration is performed on a target charging terminal based on battery power information, battery temperature status information, battery voltage status information, and power demand information to obtain priority information corresponding to the target charging terminal, including: Step S301: obtaining first weight information corresponding to battery power information, second weight information corresponding to battery temperature status information, third weight information corresponding to battery voltage status information, and fourth weight information corresponding to power demand information.

[0050] Figure 4 It is a flowchart of obtaining weight information according to an exemplary embodiment. In an optional embodiment, obtaining first weight information corresponding to battery power information, second weight information corresponding to battery temperature status information, third weight information corresponding to battery voltage status information, and fourth weight information corresponding to power demand information includes: Step S401: Based on the station type corresponding to the charging pile or the charging period corresponding to the target device, first weight information is obtained, where the first weight information is positively correlated with the charging efficiency configured for the station type and the number of target devices in the charging period.

[0051] In the disclosed embodiments, the station type corresponding to the charging pile or the charging period corresponding to the target device can affect the size of the first weight information. The station type corresponding to the charging pile refers to the type of vehicle that the charging pile supplies power to. For example, when the charging pile supplies power to a bus or a freight truck, the power supply requirement of the charging pile in this scenario is to replenish power as the main purpose. The charging pile is configured with a higher charging efficiency to achieve replenishment as soon as possible. Correspondingly, the greater the charging efficiency configured for the charging pile, the greater the value of the first weight information, so as to increase the weight corresponding to the battery power information to achieve rapid replenishment. The smaller the charging efficiency configured for the charging pile, the smaller the value of the first weight information.

[0052] However, since the number of devices connected to a charging pile varies in different charging periods of the day, for example, more users choose to charge from 11:00 to 13:00 or from 22:00 to 24:00, and the number of target devices connected to the charging pile during this period is large, the value of the first weight information at this time can be increased to increase the weight corresponding to the battery power information to increase the charging speed and shorten the charging time. The smaller the number of target devices in the charging period, the smaller the value of the first weight information.

[0053] Optionally, based on the station type corresponding to the charging pile or the charging period corresponding to the target device, the first weight information can also be obtained by determining a weight value for each according to the station type corresponding to the charging pile and the charging period corresponding to the target device, and taking the average of the two as the first weight information.

[0054] Step S402: Determine second weight information corresponding to the ambient temperature of the target device according to a preset temperature-weight correspondence relationship.

[0055] In the disclosed embodiment, the preset temperature weight correspondence indicates the correspondence between the ambient temperature and the second weight information. The preset temperature weight correspondence may be an ambient temperature-weight information relationship curve, which may be determined based on experimental data of the battery's charge and discharge performance at different ambient temperatures. According to the ambient temperature value of the target device, the weight value corresponding to the ambient temperature value in the preset temperature weight correspondence may be determined, and the weight value may be determined as the second weight information.

[0056] Step S403: based on the charging mode corresponding to the target device, obtain third weight information, where the third weight information is positively correlated with the charging power corresponding to the charging mode.

[0057] In the disclosed embodiment, different charging modes correspond to different charging powers, for example, the charging power in the fast charging mode is greater than the charging power in the normal charging mode. Increasing the third weight information at a high charging power can improve the weight corresponding to the battery voltage state information to improve the charging efficiency. Therefore, the greater the charging power corresponding to the charging mode, the greater the value of the third weight information, and the smaller the charging power corresponding to the charging mode, the smaller the value of the third weight information.

[0058] Step S404: Based on the station type corresponding to the charging pile, the charging period corresponding to the target device, or the ambient temperature of the target device, obtain fourth weight information. The fourth weight information is positively correlated with the charging efficiency configured for the station type, positively correlated with the number of target devices in the charging period, and has a preset temperature weight correspondence with the ambient temperature.

[0059] In the disclosed embodiment, the type of station corresponding to the charging pile, the charging period corresponding to the target device, or the ambient temperature of the target device can affect the size of the fourth weight information. The greater the charging efficiency configured for the charging pile, the greater the value of the fourth weight information, so as to increase the weight corresponding to the power demand information to achieve rapid charging. The smaller the charging efficiency configured for the charging pile, the smaller the value of the fourth weight information.

[0060] Since the number of devices connected to a charging pile is different in different charging periods of the day, and the number of target devices connected to the charging pile is relatively large in a certain period, the value of the fourth weight information at this time is increased to increase the weight corresponding to the battery power information to increase the charging speed and shorten the charging time. The smaller the number of target devices in the charging period, the smaller the value of the fourth weight information.

[0061] In addition, the weight value corresponding to the ambient temperature value in the preset temperature-weight correspondence relationship may be determined according to the ambient temperature value of the target device, and the weight value may be determined as the fourth weight information.

[0062] Optionally, based on the station type corresponding to the charging pile, the charging period corresponding to the target device, or the ambient temperature of the target device, the fourth weight information can also be obtained by determining a weight value respectively according to the station type corresponding to the charging pile, the charging period corresponding to the target device, and the ambient temperature of the target device, and taking the average of the weight values ​​as the fourth weight information.

[0063] In an optional embodiment, the first weight information, the second weight information, the third weight information and the fourth weight information can be determined by a remote server according to the station type corresponding to the charging pile, the charging time period corresponding to the target device, the preset temperature weight correspondence and the ambient temperature of the target device, and sent to the charging pile in real time, or can be directly modified by a technician on a local human-machine interface according to the station type corresponding to the charging pile, the charging time period corresponding to the target device, the preset temperature weight correspondence and the ambient temperature of the target device to adapt to the charging requirements of different stations, different time periods and different application scenarios.

[0064] Based on the above, it can be known that in the embodiment of the present disclosure, the first weight information is obtained based on the station type corresponding to the charging pile or the charging time period corresponding to the target device, the second weight information corresponding to the ambient temperature of the target device is determined according to the preset temperature-weight correspondence relationship, and the third weight information is obtained based on the charging mode corresponding to the target device; the fourth weight information is obtained based on the station type corresponding to the charging pile, the charging time period corresponding to the target device, or the ambient temperature of the target device. The weight information can be adapted to the charging requirements of different stations, different time periods, and different application scenarios, so that the weight information is more accurate.

[0065] Step S302: Based on the first weight information, the second weight information, the third weight information and the fourth weight information, weighted statistics are performed on the battery power information, the battery temperature status information, the battery voltage status information and the power demand information to obtain priority information.

[0066] In the embodiment of the present disclosure, based on the first weight information, the second weight information, the third weight information and the fourth weight information, the battery power information, the battery temperature status information, the battery voltage status information and the power demand information are weighted and counted, and the priority information can be calculated by the following formula (3): (3) In formula (3), is the priority information, is the first weight information, the constant 1 represents 100% power, For battery power information, is the second weight information, is the battery temperature status information, is the third weight information, is the battery voltage status information, is the fourth weight information, For power demand information.

[0067] Based on the above, it can be known that in the embodiment of the present disclosure, by introducing the first weight information, the second weight information, the third weight information and the fourth weight information, it is possible to adjust the weights of the battery power information, the battery temperature status information, the battery voltage status information and the power demand information in the priority information calculation process by adjusting the weight information, so as to obtain more accurate priority information.

[0068] Step S203: Based on the priority information, a power unit for supplying power is allocated to the target charging terminal from a plurality of power units in the charging pile.

[0069] In an optional embodiment, the priority information is any priority of a plurality of different levels of priorities. When the number of priority levels is 2, all levels are S1 and S2 from high to low, and S1 is higher than S2. If the priority information obtained according to the above calculation is higher than the preset priority threshold, it is S1, otherwise it is S2. When the number of priority levels is 3, all levels are S1, S2, and S3 from high to low, and S1 is higher than S2, and S2 is higher than S3. In this case, a first preset priority threshold and a second preset priority threshold are set, and the first preset priority threshold is greater than the second preset priority threshold. If the priority information obtained according to the above calculation is higher than the first preset priority threshold, it is S1, if it is between the first preset priority threshold and the second preset priority threshold, it is S2, and if it is less than the second preset priority threshold, it is S3.

[0070] Figure 5 The present invention is a flowchart of allocating power units according to priority information according to an exemplary embodiment. Based on the priority information, a power unit for supplying power is allocated to a target charging terminal from a plurality of power units in a charging pile, including: Step S501: when the priority information is the first priority, allocating a power unit for supplying power to a target charging terminal from a plurality of power units; Step S502: When the priority information is the second priority level, determine at least one priority level higher than the second priority level, and obtain the remaining power units, as well as the power units allocated to the target charging terminal from the remaining power units; the remaining power units are power units among the multiple power units except for the power units allocated to the charging terminal corresponding to at least one priority level.

[0071] In the disclosed embodiment, since the charging requirements of devices connected to different charging terminals are different, the priorities corresponding to different charging terminals may be the same or different.

[0072] In the case where the priorities corresponding to the multiple charging terminals of the charging pile are different, the first priority is the highest level among all priorities. When the priority information is the first priority, the charging demand of the target charging terminal is met first, and the power unit for power supply is directly allocated to the target charging terminal from multiple power units. When the priority information is the second priority, it is necessary to allocate power units to other charging terminals with higher priorities before allocating power units to the target charging terminal of the second priority to meet the charging demand of the target device connected to the target charging terminal as much as possible. Therefore, before allocating power units to the target charging terminal of the second priority, first determine at least one priority level higher than the second priority level, and obtain the power unit allocated to the charging terminal corresponding to at least one priority level higher than the second priority level, determine the remaining power units, and then allocate power units to the target charging terminal from the remaining power units.

[0073] In the case where the priorities corresponding to the multiple charging terminals of the charging pile are the same, a power unit for supplying power is sequentially allocated to each charging terminal from the multiple power units until all the multiple power units are allocated.

[0074] Based on the above, it can be known that in the embodiment of the present disclosure, when the priority information is the first priority, a power unit for supplying power is allocated to the target charging terminal from multiple power units; when the priority information is the second priority, a power unit for supplying power is allocated to the target charging terminal from multiple power units except for the power units allocated to the charging terminal corresponding to at least one priority level. This enables power units to be preferentially configured for high-level charging terminals to meet the power requirements of the high-level charging terminals, and the power requirements of lower-level charging terminals to be met as much as possible after the power requirements of the high-level charging terminals are met.

[0075] In an optional embodiment, allocating a power unit to a target charging terminal needs to take into account power demand information corresponding to the charging terminal, and the method further includes: According to the power demand information, the target number of power units is determined.

[0076] In the embodiment of the present disclosure, determining the target number of power units according to the power demand information may be to divide the required power indicated by the power demand information by the output power of a single power unit to obtain the target number of power units. Taking the required power as 100kw and the output power of a single power unit as an example, if it is to be fully matched, 2.5 power units need to be allocated to it, and since a single power unit cannot be divided and allocated again, in order to meet its power demand, 3 power units need to be allocated to it.

[0077] Therefore, in consideration of the power demand information, allocating a power unit for supplying power to the target charging terminal from a plurality of power units includes: allocating a target number of power units to the target charging terminal from a plurality of power units.

[0078] In the embodiment of the present disclosure, the power units for allocating the target power unit number to the target charging terminal from the multiple power units may be randomly selected power units for the target power unit number and allocated to the target charging terminal. Alternatively, the power units for the target power unit number with consecutive numbers may be allocated to the target charging terminal according to the numbers of the power units.

[0079] Allocating power units for supplying power to a target charging terminal from the remaining power units includes: when the number of remaining power units is greater than the target number of power units, allocating the target number of power units from the remaining power units to the target charging terminal; when the number of remaining power units is less than or equal to the target number of power units, allocating the remaining power units to the target charging terminal.

[0080] In the embodiment of the present disclosure, since the remaining power units are power units other than the power units allocated to the charging terminal corresponding to at least one priority level among the multiple power units, the number of remaining power units may not be able to meet the needs of the target charging terminal. Therefore, it is necessary to compare the relationship between the number of remaining power units and the target number of power units. When the number of remaining power units is greater than the target number of power units, the target number of power units are allocated to the target charging terminal from the remaining power units; when the number of remaining power units is less than or equal to the target number of power units, the remaining power units are allocated to the target charging terminal.

[0081] Based on the above, it can be known that in the embodiment of the present disclosure, by determining the target number of power units according to the power demand information, it is possible to determine the number of power units that meet the power demand of the charging terminal, and allocate power units for supplying power to the target charging terminal based on the target number of power units.

[0082] In a specific implementation, the implementation process of the above power unit allocation method is as follows: Figure 6 As shown, the battery power information, battery temperature status information, battery voltage status information and power demand information corresponding to the target device required for the above power unit allocation, as well as the weight information corresponding to each piece of information, are re-acquired once every preset time interval, and the power unit allocation calculation is re-performed based on the new information acquired each time, and the power units in the charging pile are reallocated so that the allocation of power units can adapt to charging changes. Optionally, the preset time interval can be 1 minute or 30 seconds.
