Description

Technical Field

[0001] The present invention relates to the technical field of charging pile power distribution, and particularly relates to a power unit distribution method, device, electronic device and storage medium. Background Art

[0002] With the development of electric vehicles, the demand for charging facilities has increased rapidly. Existing charging piles usually have multiple charging terminals externally connected to achieve simultaneous charging of multiple electric vehicles. The power sources of multiple charging terminals are multiple power units in the charging pile. To meet the charging requirements of multiple charging terminals, it is necessary to allocate multiple power units to multiple charging terminals for power supply. In related technologies, the power units are usually directly bound to the charging terminals one by one. However, when the charging terminals are connected to different devices to be charged, the charging requirements are different. The power unit distribution method of binding the power units to the charging terminals one by one makes the output of the power units often not match the charging requirements.

[0061] Please refer to Figure 1 , Figure 1 which is a schematic diagram of an application environment shown according to an exemplary embodiment. As Figure 1 shown, the application environment may include a server 01 and a terminal 02.

[0062] In an alternative embodiment, the server 01 may perform computational processing on the power unit allocation method.

The target charging terminal is the charging terminal connected to the target device, and the priority information is used to indicate the power supply priority of the target charging terminal among multiple charging terminals in the charging pile. The target charging terminal belongs to multiple charging terminals; the 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.

[0065] In addition, it should be noted that Figure 1 what is shown is only an application environment provided by the present disclosure. In actual applications, other application environments may also be included.

[0066] In the embodiments of this specification, the above-mentioned server 01 and terminal 02 may be directly or indirectly connected through wired or wireless communication methods, and the present disclosure does not limit this here.

[0067] Figure 2 is a flowchart of a power unit allocation method shown according to an exemplary embodiment, as Figure 2 shown, the power unit allocation method includes the following:

[0068] Step S201: Obtain the battery power information, battery temperature status information, battery voltage status information, and power demand information corresponding to the target device.

[0069] In the embodiments of the present disclosure, the target device may be a vehicle powered by a battery, such as an electric vehicle, an electric bicycle, etc. Among them, the electric vehicle may be an electric vehicle for different purposes, such as a sedan, a bus, a truck, etc. The battery capacities and power demands of different target devices are different. In the embodiments of the present disclosure, the object for obtaining the battery power information, battery temperature status information, battery voltage status information, and power demand information may be a charging pile connected to the target device, or a controller or server for allocating power units to the charging pile.

[0070] 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, access the battery power storage unit in the battery management system of the target device to obtain the battery power information (State of Charge, SOC) currently corresponding to the target device. The battery power information is usually expressed in the form of a percentage, such as 20% or 60%.

[0071] In an optional embodiment, the process of obtaining the battery temperature status information includes:

[0072] Obtain the battery temperature value of the target device; in the case where the battery temperature value is within the preset battery temperature range, determine the first preset constant as the battery temperature normalization value corresponding to the target device; in the case where the battery temperature value is not within the preset battery temperature range and the absolute value of the difference from the upper limit or lower limit of the preset battery temperature range is less than or equal to the preset temperature difference, determine the second preset constant as the battery temperature normalization value corresponding to the target device, and the second preset constant is less than the first preset constant; in the case where the battery temperature value is not within the preset battery temperature range and the absolute value of the difference from the upper limit or lower limit of the preset battery temperature range is greater than the preset temperature difference, determine the third preset constant as the battery temperature normalization value corresponding to the target device, and the third preset constant is less than the second preset constant; determine the battery temperature normalization value as the battery temperature status information.

[0073] In the embodiments of the present disclosure, obtaining the battery temperature value of the target device may be to access the battery temperature storage unit in the battery management system of the target device after establishing a connection relationship between the target device and the charging pile, so as to obtain the current corresponding battery temperature value of the target device. This battery temperature value can be collected by a temperature sensor and stored in the battery temperature storage unit.

[0074] The preset battery temperature range can be determined according to the optimal operating temperature range corresponding to the battery. Exemplarily, when the optimal operating temperature range corresponding to the battery is 20° to 40°, the preset battery temperature range can be [20, 40]. The first preset constant can be set to 1. When the battery temperature value is within the preset battery temperature range, 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 status information.

[0075] Denote the preset temperature difference as Δt. Then, the temperature range that is not within the preset battery temperature range and the absolute value of the difference from the upper limit value or the lower limit value of the preset battery temperature range 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. Exemplarily, if the preset temperature difference is 15°, the temperature range that is not within the preset battery temperature range and the absolute value of the difference from the upper limit value or the lower limit value of the preset battery temperature range 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 within the preset battery temperature range and the absolute value of the difference from the upper limit value or the lower limit value of the preset battery temperature range 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 status information.

[0076] The temperature range that is not within the preset battery temperature range and the absolute value of the difference from the upper limit value or the lower limit value of the preset battery temperature range 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. Exemplarily, if the preset temperature difference is 15°, the temperature range that is not within the preset battery temperature range and the absolute value of the difference from the upper limit value or the lower limit value of the preset battery temperature range 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 within the preset battery temperature range and the absolute value of the difference from the upper limit value or the lower limit value of the preset battery temperature range is greater than the preset temperature difference, the constant 0.2 is determined as the battery temperature normalization value corresponding to the target device.

[0077] Based on the above, in the embodiments of the present disclosure, according to the temperature range in which the battery temperature value of the target device is located, the corresponding preset constant is determined as the battery temperature state information, which can reflect the current battery temperature state of the target device through the preset constant, and normalized battery temperature state information is obtained.

[0078] In an alternative embodiment, the process of obtaining the battery voltage state information includes:

[0079] Obtain the current highest single-cell voltage of the target device and the highest single-cell battery voltage configured for the target device; determine the ratio of the current highest single-cell voltage to the highest single-cell battery voltage as the target voltage ratio; determine the difference between the fourth preset constant and the target voltage ratio as the battery voltage state information.

[0080] In the embodiments of the present disclosure, the manner of obtaining the current highest single-cell voltage of the target device and the highest single-cell battery voltage configured for the target device may be to access the voltage management unit in the battery management system of the target device after establishing a connection relationship between the target device and the charging pile, so as to obtain the current highest single-cell voltage of the target device and the highest single-cell battery voltage configured for the target device. Among them, the current highest single-cell voltage can be collected by a voltage sensor and stored in the voltage management unit.

[0081] The above process of 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 state information can be calculated by the following formula (1):

[0082] (1)

[0083] In formula (1), is the battery voltage state information, constant 1 is the fourth preset constant, is the current highest single-cell voltage, is the highest single-cell battery voltage.

[0084] Based on the above, in the embodiments 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 state information, quantized battery voltage state information can be obtained through the above calculation.

[0085] In an alternative embodiment, the process of obtaining the power demand information includes:

[0086] 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 the power demand information.

[0087] In the embodiments of the present disclosure, the method for obtaining the required voltage value and required current value corresponding to the target device may be to, after establishing a connection relationship between the target device and the charging pile, respectively access the voltage management unit and current management unit in the battery management system of the target device to obtain the required voltage value and required current value corresponding to the target device.

[0088] The 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):

[0089] (2)

[0090] In formula (2), is the power demand information, is the required voltage value, is the required current value.

[0091] Step S202: Based on the battery power information, battery temperature status information, battery voltage status information, and power demand information, perform priority configuration on the target charging terminal to obtain the priority information corresponding to the target charging terminal. The target charging terminal is the charging terminal connected to the target device, and 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.

[0092] In the embodiments of the present disclosure, the charging terminal is a charging gun configured by the charging pile. The establishment of a connection and confirmation of the connection relationship between the target charging terminal and the target device may be that the target charging terminal is connected to the charging port of the target device and forms a circuit.

[0093] Figure 3 FIG. is a flowchart of a priority configuration shown according to an exemplary embodiment. In an alternative embodiment, performing priority configuration on the target charging terminal based on the battery power information, battery temperature status information, battery voltage status information, and power demand information to obtain the priority information corresponding to the target charging terminal includes:

[0094] Step S301: Obtain the first weight information corresponding to the battery power information, the second weight information corresponding to the battery temperature status information, the third weight information corresponding to the battery voltage status information, and the fourth weight information corresponding to the power demand information.

[0095] Figure 4 FIG. is a flowchart of a method for obtaining weight information shown according to an exemplary embodiment. In an alternative embodiment, obtaining the first weight information corresponding to the battery power information, the second weight information corresponding to the battery temperature status information, the third weight information corresponding to the battery voltage status information, and the fourth weight information corresponding to the power demand information includes:

[0096] Step S401: Obtain first weight information based on the station type corresponding to the charging pile or the charging period corresponding to the target device. The first weight information is positively correlated with the configured charging efficiency of the station type and positively correlated with the number of target devices during the charging period.

[0097] In the embodiments of the present disclosure, the station type corresponding to the charging pile or the charging period corresponding to the target device can affect the magnitude of the first weight information. The station type corresponding to the charging pile refers to the vehicle type powered by the charging pile. For example, when the charging pile powers a bus or a freight vehicle, the power supply requirement of the charging pile in this scenario is mainly for supplementary charging. Then, the charging pile is configured with a relatively large charging efficiency to achieve rapid supplementary charging. 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 supplementary charging. The smaller the charging efficiency configured for the charging pile, the smaller the value of the first weight information.

[0098] Since the number of devices connected to a charging pile is different at different charging periods of a day. For example, more users choose to charge from 11:00 to 13:00 or from 22:00 to 24:00. Then, the number of target devices connected to the charging pile during this period is relatively large. The value of the first weight information can be increased at this time to increase the weight corresponding to the battery power information to achieve an increase in the charging speed and a shortening of the charging time. The smaller the number of target devices during the charging period, the smaller the value of the first weight information.

[0099] Optionally, obtaining the first weight information based on the station type corresponding to the charging pile or the charging period corresponding to the target device may also be to determine a weight value according to the station type corresponding to the charging pile and the charging period corresponding to the target device respectively, and take the average of the two as the first weight information.

[0100] Step S402: Determine second weight information corresponding to the ambient temperature where the target device is located according to the preset temperature-weight correspondence.

[0101] In the embodiments of the present disclosure, 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, and this curve can be determined according to the experimental data of the charge and discharge performance of the battery at different ambient temperatures. According to the ambient temperature value where the target device is located, the weight value corresponding to this ambient temperature value in the preset temperature-weight correspondence can be determined, and this weight value is determined as the second weight information.

[0102] Step S403: Obtain third weight information based on the charging mode corresponding to the target device. The third weight information is positively correlated with the charging power corresponding to the charging mode.

[0103] In the embodiments of the present disclosure, the charging power corresponding to different charging modes is different. For example, the charging power in the fast charging mode is greater than that in the normal charging mode. Increasing the third weight information at a high charging power can increase 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.

[0104] Step S404: Obtain fourth weight information based on the station type corresponding to the charging pile, the charging period corresponding to the target device, or the environmental temperature where the target device is located. The fourth weight information is positively correlated with the charging efficiency configured for the station type, positively correlated with the number of target devices during the charging period, and has a preset temperature weight correspondence relationship with the environmental temperature.

[0105] In the embodiments of the present disclosure, the station type corresponding to the charging pile, the charging period corresponding to the target device, or the environmental temperature where the target device is located can affect the magnitude of the fourth weight information. The greater the charging efficiency configured for the charging pile, the greater the value of the fourth weight information to increase the weight corresponding to the power demand information to achieve fast charging. The smaller the charging efficiency configured for the charging pile, the smaller the value of the fourth weight information.

[0106] Since the number of devices connected to a charging pile is different during different charging periods of a day, if the number of target devices connected to the charging pile is large at 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 improve the charging speed and shorten the charging time. The smaller the number of target devices during the charging period, the smaller the value of the fourth weight information.

[0107] In addition, the weight value corresponding to the environmental temperature value in the preset temperature weight correspondence relationship can be determined according to the environmental temperature value where the target device is located, and this weight value is determined as the fourth weight information.

[0108] Optionally, obtaining the fourth weight information based on the station type corresponding to the charging pile, the charging period corresponding to the target device, or the environmental temperature where the target device is located can also be to respectively determine a weight value according to the station type corresponding to the charging pile, the charging period corresponding to the target device, and the environmental temperature where the target device is located, and taking the average value of each weight value as the fourth weight information.

[0109] 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 period corresponding to the target device, the preset temperature weight correspondence, and the ambient temperature where the target device is located, and then sent to the charging pile in real time, or directly modified by a technician on the local human-machine interface according to the station type corresponding to the charging pile, the charging period corresponding to the target device, the preset temperature weight correspondence, and the ambient temperature where the target device is located, so as to meet the charging requirements of different stations, different periods, and different application scenarios.

[0110] Based on the above, in the embodiments of the present disclosure, the first weight information is obtained according to the station type corresponding to the charging pile or the charging period corresponding to the target device, the second weight information corresponding to the ambient temperature where the target device is located is determined according to the preset temperature weight correspondence, 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 period corresponding to the target device, or the ambient temperature where the target device is located, which can make the weight information meet the charging requirements of different stations, different periods, and different application scenarios, and make the weight information more accurate.

[0111] Step S302: Based on the first weight information, the second weight information, the third weight information, and the fourth weight information, perform weighted statistics on the battery power information, the battery temperature status information, the battery voltage status information, and the power demand information to obtain priority information.

[0112] In the embodiments of the present disclosure, based on the first weight information, the second weight information, the third weight information, and the fourth weight information, performing weighted statistics on the battery power information, the battery temperature status information, the battery voltage status information, and the power demand information to obtain priority information can be calculated by the following formula (3):

[0113] (3)

[0114] In formula (3), is the priority information, is the first weight information, and the constant 1 represents 100% power, is the 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, is the power demand information.

[0115] Based on the above, in the embodiments 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 respectively in the calculation process of the priority information through the adjustment of the weight information, so as to obtain more accurate priority information.

[0116] Step S203: Based on the priority information, allocate a power unit for power supply to the target charging terminal from multiple power units in the charging pile.

[0117] In an alternative embodiment, the priority information is any one of multiple different levels of priorities. When the number of priority levels is 2, all levels are, from high to low, level S1 and level S2, where level S1 is higher than level S2. If the priority information calculated as described above is higher than the preset priority threshold, it is level S1; otherwise, it is level S2. When the number of priority levels is 3, all levels are, from high to low, level S1, level S2, and level S3, where level S1 is higher than level S2 and level S2 is higher than level 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 calculated as described above is higher than the first preset priority threshold, it is level S1; if it is between the first preset priority threshold and the second preset priority threshold, it is level S2; if it is less than the second preset priority threshold, it is level S3.

[0118] Figure 5 It is a flowchart of allocating a power unit according to priority information shown in an exemplary embodiment. Based on the priority information, allocate a power unit for power supply to the target charging terminal from multiple power units in the charging pile, including:

[0119] Step S501: When the priority information is the first priority, allocate a power unit for power supply to the target charging terminal from multiple power units;

[0120] Step S502: When the priority information is the second priority, determine at least one priority higher than the second priority, obtain the remaining power units, and allocate a power unit for power supply to the target charging terminal from the remaining power units; the remaining power units are the power units other than those allocated to the charging terminals corresponding to at least one priority among the multiple power units.

[0121] In the embodiments of the present disclosure, since the charging requirements of the devices connected to different charging terminals are different, the priorities corresponding to different charging terminals may be the same or different.

[0122] When the priorities corresponding to multiple charging terminals of a charging pile are different, the first priority is the highest among all priorities. When the priority information is the first priority, the charging demand of the target charging terminal is satisfied first, and the power unit for supplying power to the target charging terminal is directly allocated from multiple power units. When the priority information is the second priority, after allocating power units for other charging terminals with higher priorities, the power unit for the target charging terminal with the second priority is allocated to try to meet the charging demand of the target device connected to the target charging terminal. Therefore, before allocating the power unit for the target charging terminal with the second priority, at least one priority higher than the second priority is first determined, and the situation of the power units allocated to the charging terminals corresponding to at least one priority higher than the second priority is obtained, the remaining power units are determined, and then the power unit for supplying power to the target charging terminal is allocated from the remaining power units.

[0123] When the priorities corresponding to multiple charging terminals of a charging pile are the same, the power units for supplying power to each charging terminal are sequentially allocated from multiple power units until all the power units are allocated.

[0124] Based on the above, in the embodiment of the present disclosure, when the priority information is the first priority, the power unit for supplying power to the target charging terminal is allocated from multiple power units. When the priority information is the second priority, the power unit for supplying power to the target charging terminal is allocated from the power units other than the power units allocated to the charging terminals corresponding to at least one priority, so as to be able to preferentially configure power units for high-level charging terminals to meet the power requirements of high-level charging terminals, and as much as possible meet the power requirements of lower-level charging terminals after meeting the power requirements of high-level charging terminals.

[0125] In an optional embodiment, when allocating a power unit for a target charging terminal, the power demand information corresponding to the charging terminal needs to be considered, and the above method further includes:

[0126] Determine the target number of power units according to the power demand information.

[0127] In the embodiment of the present disclosure, determining the target number of power units according to the power demand information may be dividing 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 of 100 kw and the output power of a single power unit of 40 kw as an example, if a perfect match is required, 2.5 power units need to be allocated to it. However, since a single power unit cannot be divided and allocated again, in order to meet its power requirement, 3 power units need to be allocated to it.

[0128] Therefore, when considering the power demand information, power units for supplying power to the target charging terminal are allocated from multiple power units, including: allocating power units with a target number of power units for the target charging terminal from multiple power units.

[0129] In the embodiments of the present disclosure, the power units with a target number of power units allocated for the target charging terminal from multiple power units can be randomly selected and allocated to the target charging terminal. It can also be that, according to the numbers of the power units, power units with a consecutive target number of power units are allocated to the target charging terminal.

[0130] Power units for supplying power to the target charging terminal are allocated from the remaining power units, including: when the number of the remaining power units is greater than the target number of power units, allocating power units with a target number of power units for the target charging terminal from the remaining power units; when the number of the 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.

[0131] In the embodiments of the present disclosure, since the remaining power units are the power units other than those allocated for the charging terminals corresponding to at least one priority among multiple power units, the number of the remaining power units may not be able to meet the requirements of the target charging terminal. Therefore, it is necessary to compare the relationship between the number of the remaining power units and the target number of power units. When the number of the remaining power units is greater than the target number of power units, allocating power units with a target number of power units for the target charging terminal from the remaining power units; when the number of the 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.

[0132] Based on the above, in the embodiments of the present disclosure, by determining the target number of power units according to the power demand information, the number of power units that meet the power requirements of the charging terminal can be determined, and power units for supplying power to the target charging terminal are allocated based on the target number of power units.

[0133] In a specific implementation manner, the implementation process of the above power unit allocation method is as Figure 6 shown. The battery power information, battery temperature status information, battery voltage status information, and power demand information of the target device required for the above power unit allocation, as well as the weight information corresponding to each information, are re-obtained at intervals of a preset time interval, and the power unit allocation calculation is re-performed according to the newly obtained information each time, and each power unit in the charging pile is re-allocated, so that the allocation of power units adapts to the charging changes. Optionally, the preset time interval can be 1 minute or 30 seconds.
