Description

Technical Field

[0001] The present application relates to the field of energy management, and particularly to a charging method, device, charging management system, and storage medium. Background Art

[0002] Currently, energy storage battery systems and electric vehicle charging technologies have gradually matured and been widely applied. The core functions of mainstream charging devices on the market focus on electric energy storage and unidirectional energy supply, that is, taking battery charge and discharge as the core to achieve the management of power input and output. However, in related technologies, charging devices applied to scenarios such as energy storage batteries and power batteries usually operate independently, and their control strategies only perform local power distribution for individual devices. Neither a management system based on goals such as carbon emission intensity and economic cost has been established, nor is there a global collaborative scheduling mechanism across devices, resulting in the difficulty of releasing the overall energy efficiency and carbon emission reduction potential of the system.

[0057] This embodiment provides a charging method. Figure 2 It is a flowchart of a charging method according to an embodiment of the present application, as Figure 2 shown. The process includes the following steps:

[0058] Step S210, obtain target management indicators corresponding to multiple charging devices, and allocate a first priority to each charging device according to the target management indicators.

[0059] Among them, this embodiment can be applied to a battery management system (BMS). The power line of the charging device is connected to the battery, and the communication line is connected to the BMS. Please refer to Figure 3, different charging devices at the battery input end can be classified into multiple types according to different data transfer modes, including: the first type of charging device, which is connected to the BMS and the battery through the first communication line and the first power line respectively. The BMS can obtain electrical data such as voltage, current, and power of the charging device, as well as carbon emission data through the first communication line; the second type of charging device, which is connected to the BMS and the battery through the second communication line and the second power line respectively. The BMS can obtain carbon emission data through the second communication line, and other electrical data needs to be obtained by the BMS from the second power line with the help of corresponding sensors, such as voltage, current, and power, etc.; the third type of charging device, which is connected to the battery through the third power line. Electrical data needs to be obtained by the BMS from the power line with the help of corresponding sensors, such as voltage, current, and power, etc., and the carbon emission data is pre-entered into the BMS internally with fixed parameters.

[0060] Target management indicators are a series of parameters or criteria used to measure the performance, efficiency, or environmental impact of charging devices. These indicators are usually used to evaluate the overall effectiveness of the device for priority setting or optimization management. In this embodiment, the target management indicators may include charging efficiency, charging speed, device health status, operating costs (such as power consumption, maintenance costs), or carbon emission coefficient, etc.: Charging efficiency can be used to measure the percentage of input electrical energy converted into stored electrical energy by the device; high efficiency means less energy loss and more environmental friendliness. Charging speed represents the time required for the device to charge from a low battery state to a full charge. Fast charging technology can significantly reduce waiting time. The device health status reflects the service life, wear degree, and maintenance status of the charging device; a device in good health is more reliable and has a lower failure rate. The carbon emission coefficient is used to quantify the carbon emissions generated by the charging device throughout its life cycle (including manufacturing, operation, and scrapping); a low carbon emission coefficient means that the device has a smaller impact on the environment.

[0061] Next, according to the obtained target management indicators, a corresponding first priority is assigned to each charging device. The priority may be based on a weighted evaluation of multiple factors. For example, a device with a faster charging speed may be given a higher priority, or a device with a better health status or a lower carbon emission coefficient may be given priority.

[0062] Step S220, detecting the target progress information of the power consumption unit; the target type of the target progress information matches the target type of the target management indicator.

[0063] On the one hand, different loads at the battery output end can be classified into multiple types according to the range of electricity consumption types, including: single equipment, generally large single power-consuming equipment, such as large air-conditioning compressors for buildings, entire automated production line equipment, etc., to detect and manage the carbon emissions of single equipment; single users, which can be single households, office users, or enterprise users, etc. Such users are identified and represented by enterprises, families, or individuals to control low carbon emissions; designated areas, all loads within the designated area, generally divided by geographical areas, such as industrial areas, residential areas, parks, villages, etc. Such users control low carbon emissions reduction in units of areas. For the convenience of subsequent description, the above are collectively referred to as electricity consumption units. Please refer to Figure 4 , the power lines of each user unit divided according to single equipment, single users, and designated areas are connected to the battery, and the communication lines are connected to the BMS.

[0064] On the other hand, the target progress information refers to the current state or progress of the electricity consumption unit during the charging process, and this information helps to characterize the demand and charging progress of the electricity consumption unit. The target progress information can include information such as the charging percentage, remaining charging time, charging rate, or carbon emission progress information. Among them, the charging percentage is used to display the percentage of the current charged electricity of the electricity consumption unit in the total electricity. The remaining charging time represents the time required for the electricity consumption unit to reach the full charge state predicted based on the current charging speed. The charging rate is the instantaneous charging speed at the current moment. The carbon emission progress information can represent the carbon emissions already generated by the electricity consumption unit during the charging process or the carbon emissions expected to be generated during the entire charging cycle.

[0065] Taking carbon emissions as an example, each electricity consumption unit is matched with a corresponding carbon emission target, which can be a short-term target (such as monthly or quarterly), or a long-term target (such as annual, five-year, or ten-year, etc.). Users can conduct segmented management according to the carbon emission target. For example, the annual target can be decomposed into monthly targets, and the segmented management plan can be sent to the BMS through data transmission methods such as firmware burning, peripheral device sending, and cloud. The BMS performs real-time management of carbon source input according to the segmented targets to meet the requirements of achieving the final goal through segmented management.

[0066] In actual operation, the target progress information is more commonly used to guide the management and selection of charging equipment. For example, an electricity consumption unit with a low battery level may require a device with a faster charging speed to quickly restore the battery level, while an electricity consumption unit close to the full charge state may be more suitable for using a device with higher charging efficiency and lower carbon emission coefficient to complete the final charging.

[0067] In addition, it should be ensured that the type of the detected target progress information matches the type of the target management indicator used to allocate the priority of the charging device. For example, if the target management indicator includes a carbon emission coefficient, the detected target progress information should be able to reflect the state or progress related to this indicator during the charging process of the power consumption unit, that is, the target progress information correspondingly includes carbon emission progress information. Based on the above target management information and the associated target progress information, the optimization of the charging device management implemented for the carbon emission management target, cost target or other targets can be achieved.

[0068] Step S230: Based on the first priority and the target progress information, determine a target charging device from each charging device, and control the target charging device to charge the power consumption unit.

[0069] Specifically, in combination with the first priority determined in the above step S210 and the target progress information of the user unit obtained in the above step S220, one or more most suitable charging devices are selected from all available charging devices as the target charging device. Once the target charging device is determined, the system will send an instruction to control the device to start or continue charging the power consumption unit. For example, the above BMS can control the start-stop state of the corresponding target charging device through a communication line or a power switch arranged on the power line, or adjust the real-time power of the corresponding target charging device through the communication line.

[0070] More specifically, taking the carbon emission coefficient as the target management indicator as an example, each charging device is ranked according to the value of the obtained carbon emission coefficient, and the lower the carbon emission coefficient of the charging device, the higher the first priority assigned to it. Then in this embodiment, when multiple charging devices are available for charging and the power is sufficient, the charging device with low carbon emissions can be preferably selected for charging according to the first priority and the target progress information of each power consumption unit. Through the above method, the carbon emission management of different charging devices at the input end and the carbon emission management of different power consumption units at the output end can be realized, and finally the carbon emission management of the energy flow between the input end and the power consumption unit end is realized, that is, the input end can directly supply power to the power consumption unit end without passing through the battery, and the carbon emissions and the input-output end relationship of both can be controlled. By reasonably allocating the power and duration of different carbon emission management targets at the input and output ends, the optimal carbon emission energy utilization is effectively realized.

[0071] In the above charging method, by comprehensively considering indicators such as the performance and carbon emission status of the charging device and the current demand of the power consumption unit, the charging device is intelligently selected and controlled to achieve more efficient, safe and reliable charging management; this management method is particularly suitable for scenarios that need to manage a large number of charging devices and various types of power consumption units, such as electric vehicle charging stations, large-scale electronic device charging centers, etc., thus effectively improving the multi-device cooperation ability in the charging control process.

[0072] In some of these embodiments, when the above-mentioned target management index is the carbon emission factor, the above-mentioned obtaining the target management indexes corresponding to multiple charging devices may further include the following steps:

[0073] Obtain the emission source type of each charging device; if the emission source type indicates that the charging device is a static carbon emission source, obtain the first carbon emission factor pre-stored in the static carbon emission source; if the emission source type indicates that the charging device is a dynamic carbon emission source, receive the carbon emission factor per unit time of the dynamic carbon emission source sent by the communication device, and calculate the second carbon emission factor corresponding to the dynamic carbon emission source based on the carbon emission factor per unit time and the preset time window; the carbon emission factor includes the first carbon emission factor and the second carbon emission factor.

[0074] In this step, first distinguish the emission source types of each charging device, and determine whether the charging device belongs to a static carbon emission source or a dynamic carbon emission source. Among them, a static carbon emission source refers to a charging device with constant carbon emission parameters or no change in the short term and does not require real-time update, and a dynamic carbon emission source refers to a charging device with relatively fast parameter update. The judgment method for the emission source type can be: through port presetting, such as fixing certain ports for dynamic input use; through communication notification, such as informing the connected device of its type through communication such as Controller Area Network (CAN); through device presetting, such as presetting all external device types in the internal software during device installation; or through cloud distribution, that is, according to the existing device types, distribute them to the BMS through the cloud to obtain the specific emission source type of the charging device.

[0075] For the charging device whose emission source type belongs to the static carbon emission source, the first carbon emission factor corresponding to the charging device can be obtained by retrieving the pre-stored database provided by the Intergovernmental Panel on Climate Change (IPCC) or other professional institutions and calling the retrieved carbon emission factor of the charging device.

[0076] For the charging device whose emission source type belongs to the dynamic carbon emission source, the carbon emission factor sent by it can be obtained through real-time communication with a third-party device, etc. It should also be noted that since the carbon emission factor of the dynamic carbon emission source changes in real time, it is necessary to calculate the average carbon emission within a certain time period for this type of data to obtain the second carbon emission factor within the preset time window (such as 1 hour), and then rank based on the time period average carbon emission factor to avoid frequent start and stop of the charging device caused by the ranking change caused by real-time dynamic carbon emissions.

[0077] In an optional embodiment, the method for determining the above time window length may further include the following steps: obtaining change characteristic data of a dynamic carbon emission source; and determining the length of the time window based on the change characteristic data.

[0078] Among them, the change characteristic data of the dynamic carbon emission source refers to quantitative information reflecting the change of its carbon emission with time, activity level or other factors. For the change characteristic data indicating that the carbon emission of the charging device changes slowly or regularly, the time window length can be extended as much as possible to calculate the average carbon emission coefficient within a long time period; for the carbon emission data that changes frequently or has no regular pattern, the time period length can be appropriately shortened. Through the above method, the time window length can be specifically formulated according to the change characteristics of different dynamic carbon emission sources, ensuring the accuracy and representativeness of the carbon emission coefficient calculation.

[0079] Through the above embodiments, by directly obtaining the pre-stored first carbon emission coefficient, the errors caused by frequent measurement or estimation are avoided, ensuring the stability and accuracy of the data; by receiving the carbon emission coefficient per unit time sent by the communication device in real time and calculating according to the preset time window, the carbon emission characteristics of the device in different operating states can be more accurately reflected, improving the dynamics and real-time nature of the data. On this basis, the process of obtaining the carbon emission coefficient is refined and optimized, improving the accuracy and real-time nature of the data, providing strong support for the management of charging devices and energy optimization.

[0080] In some of the embodiments, the above determining the target charging device from each charging device based on the first priority and the target progress information may further include the following steps:

[0081] Detecting the power data of the battery module; and determining the target charging device from each charging device and the battery module based on the first priority, the power data and the target progress information.

[0082] Specifically, the current remaining power, voltage and other key parameters of the battery module are monitored in real time to obtain the current power data of the battery module. Then, the first priority and the target progress information are comprehensively analyzed, and the charging requirements are sorted according to the urgency or importance of the task. Consider the time window and resource consumption required to complete a specific task. Screen out the eligible target charging device from all candidate charging devices: evaluate the status of each charging device (such as whether it is close to full charge) and its service capacity in combination with the power data. Select the charging device that can meet the high-priority task fastest without affecting the execution of other tasks as the final target.

[0083] Exemplarily, if it is detected that the battery module has sufficient power (e.g., the power of the battery module is greater than a certain power threshold), it is preferred to charge the battery module, and at this time, the battery module is set as the target charging device. If it is detected that the power of the battery module (e.g., the power of the battery module is less than or equal to a certain power threshold) or the charging power of the charging device is insufficient (e.g., the charging power of the charging device is less than a certain power threshold), then in combination with the target progress information, it is preferred that the charging device with a relatively higher first priority and the battery module charge the electrical device simultaneously, and at this time, the charging device with a relatively higher first priority and the battery module are set as the target charging devices. If it is detected that the battery module has insufficient power and the charging power of the charging device is sufficient, then in combination with the target progress information, it is preferred to select at least one charging device with a relatively higher first priority to charge the electrical unit and the battery module simultaneously, and at this time, the selected charging device is set as the target charging device.

[0084] Through the above embodiments, by continuously monitoring the usage of charging resources such as battery modules, and combining historical data with real-time requirements, while ensuring the overall operation efficiency of the system, through intelligent management means, the reasonable allocation of limited charging resources is achieved to ensure that key business tasks can continuously obtain sufficient power support, so as to be able to automatically optimize the resource allocation strategy, avoid resource waste, and achieve timely, reasonable response and efficient execution.

[0085] In some of these embodiments, after determining the target charging device from each charging device and battery module, the above charging method may further include the following steps:

[0086] If the number of target charging devices is at least two, then according to the target progress information, weight values are respectively assigned to each target charging device; based on the weight values, the charging power of each target charging device is adjusted, and each target charging device is controlled to charge the electrical unit at the corresponding charging power.

[0087] In this step, the time requirements and priorities of each charging task can be analyzed first, and a weight value reflecting its importance and urgency is assigned to each target charging device. For example, urgent or high-priority tasks can obtain higher weights. Then, the charging power of each charging device is dynamically adjusted according to the weight values. High-weight devices are given higher power first to speed up the charging speed and ensure that key tasks are completed on time; low-weight devices appropriately reduce the power to optimize the overall resource allocation. Finally, charging starts at the set power, and the system status is monitored in real time. It should be understood that in case of changes (such as new tasks being added or resource fluctuations), the weights are re-evaluated in a timely manner and the power distribution is adjusted to ensure efficient operation.

[0088] Through the above embodiments, resources are dynamically allocated. By allocating weight values, the system can dynamically adjust the allocation of charging resources according to current requirements (such as target progress, battery status, urgency of power-consuming units, etc.), ensuring that critical or urgent charging tasks are given priority, so as to take into account the needs of different tasks and achieve optimal charging efficiency and system performance with limited resources. Moreover, by precisely controlling the charging power, the system can use energy more effectively, reduce unnecessary energy waste, and lower carbon emissions.

[0089] In some of these embodiments, controlling the target charging device to charge the power-consuming unit may further include the following steps:

[0090] Based on the target progress information corresponding to multiple power-consuming units, assign a second priority to each power-consuming unit; according to the second priority, control the target charging device to charge the power-consuming unit.

[0091] Taking carbon emission management as an example, when there are multiple power-consuming units, according to the speed of reaching the carbon emission target, assign corresponding second priorities to each power-consuming unit; for example, the power-consuming unit with a slower progress in reaching the carbon emission target is assigned a relatively higher second priority, and the power-consuming unit with a faster progress in reaching the carbon emission target is assigned a relatively lower second priority. In this way, during the actual charging process, preferentially assign a low-carbon emission target charging device to the user unit with a relatively slower progress in reaching the carbon emission target, that is, a relatively higher second priority; for the power-consuming unit with an excessive carbon emission progress among the power-consuming units, preferentially assign a battery module to charge this power-consuming unit. This allocation process is a real-time dynamic allocation.

[0092] In addition, when multiple charging devices, multiple power sources, and battery modules work simultaneously, it is necessary to achieve a reasonable allocation of the BMS for different carbon sources and power-consuming units. The allocation method can be, for example, Figure 5 the way of switching through a multi-way switch as shown, to select and connect each slave device with the matching power-consuming energy source to achieve the synchronous operation of two or more of them.

[0093] Through the above embodiments, when multiple power-consuming units are using electricity simultaneously, matching charging can be carried out based on the carbon emission data of the charging device and the progress of reaching the carbon emission target of the power-consuming unit, so as to achieve the purpose of balancing carbon emissions and further optimize the charging management.

[0097] It should be noted that the above-mentioned modules may be functional modules or program modules, and can be implemented either by software or by hardware. For modules implemented by hardware, the above-mentioned modules may be located in the same processor; or the above-mentioned modules may also be located in different processors in any combination form. Specific examples in this embodiment may refer to the examples described in the above-mentioned embodiments and alternative implementation manners, and will not be repeated in this embodiment.

[0098] This embodiment also provides a charging management system, including multiple charging devices and a master controller; the master controller is respectively connected to the multiple charging devices and the power consumption unit, and is configured to execute the charging method described in any of the above embodiments. Among them, the master controller refers to a hardware device such as a BMS, an energy management controller, or a local computer that is responsible for coordinating the efficient operation of multiple charging devices and the power consumption unit; it optimizes power distribution through intelligent algorithms, monitors the system status, and ensures a safe and stable charging process.

[0099] In some of these embodiments, the above system further includes a battery module; wherein, the master controller is also connected to the battery module.

[0100] In some of these embodiments, the above charging device includes: a first type of charging device connected to the main controller via a first communication line and a first power line; a second type of charging device connected to the main controller via a second communication line and a second power line; and a third type of charging device connected to the main controller via a third power line; the main controller is further configured to switch the working state of the first type of charging device through the first communication line, switch the working state of the second type of charging device through a first switch circuit provided on the second power line, and / or switch the working state of the third type of charging device through a second switch circuit provided on the third power line.

[0101] Taking the case where the main controller uses a BMS as an example, please refer to Figure 7 , the charging management system includes a BMS, a battery module, a plurality of charging devices, and a plurality of power-consuming units. Among them, each charging device accesses the BMS and the battery module via a communication line and a power line by intelligently adjusting the high and low voltage inputs; the BMS and the battery module are connected to each power-consuming unit via a communication line and a power line by intelligently adjusting the high and low voltage outputs.

[0102] As Figure 7 shown, the first type and the second type of charging devices are dynamic or static carbon emission sources, the third type is a static carbon emission source, and the third type can update the carbon emission data for the BMS irregularly through data transmission methods such as firmware flashing, peripheral distribution, and the cloud.

[0103] When charging a static carbon emission source, the BMS can collect the charging power of the charging device in real time, accumulate the charging power, multiply it by the carbon emission coefficient, and then obtain the total carbon emission of the charged power. Adding the total carbon emission of the original power in the battery can obtain the total carbon emission of all the power in the battery. Dividing the total carbon emission of all the power in the battery by the existing total power of the battery can obtain the average carbon emission.

[0104] When charging a dynamic carbon emission source, the BMS needs to collect the charging power of the charging device and the dynamic carbon emission data in real time, and dynamically accumulate the charging power, the total carbon emission of the charged power, as well as the existing total power and the total carbon emission of the battery. The accumulation method is preferably by integration. When multiple charging devices are charging simultaneously, the BMS needs to collect the charging power and the carbon emission data of multiple charging devices in real time, and dynamically accumulate the charging power of each charging device, the total carbon emission of the charged power, as well as the existing total power and the total carbon emission of the battery respectively. The accumulation method is preferably by integration.

[0105] When multiple charging devices can be charged and the power is sufficient, the BMS preferably selects a charging device with low carbon emissions for charging. For the first type of charging device, the BMS can control the start / stop and power of the charging device in real time through communication; for the second type and the third type of charging devices, a power line control switch needs to be added to control the start / stop of charging.

[0106] Among them, when the power consumption unit has no demand and the charging power and charging equipment are sufficient, the charging equipment with low carbon emissions is preferred to charge the battery. When the battery is fully charged and the carbon emissions of the charging equipment are too high, the battery is preferred to supply power to the power consumption unit. When the charging power is sufficient, the battery is not fully charged, and the carbon emissions of the charging equipment meet the requirements, both the power consumption unit and the battery are powered simultaneously. When there are multiple power consumption units, the low-carbon emission sources are preferentially allocated to those with a long way to go to meet the carbon emission targets. If there are those that have exceeded the target, the low-carbon emission sources are preferentially arranged for the battery and then allocated to the power consumption units that have exceeded the target. This allocation is a real-time dynamic allocation. When the battery is fully charged and does not need to be charged, when the carbon emissions are high, low-carbon emission sources are preferably selected to supply power to the power consumption unit; or when the charging power is insufficient, the low-carbon emission charging equipment directly supplies power to the power consumption unit to ensure the power consumption of the power consumption unit first. When multiple power consumption units are using electricity simultaneously, matching charging can be carried out based on the carbon emission data of the charging equipment, the carbon emission targets of the power consumption units, and the progress of meeting the targets, so as to achieve the effect of balancing carbon emissions and meeting the targets simultaneously.

[0107] In another embodiment, a power converter can also be added to manage multiple power consumption units and charging equipment. Specifically, the BMS can determine the number of selected charging equipment and the charge and discharge status of the battery according to the carbon emission status and power of the charging equipment, and the carbon emission status and power of the battery. The power converter adjusts the power of the power consumption unit and the battery according to the BMS instruction. Among them, the battery power interface is a bidirectional charge and discharge port, which can realize the charging and discharging of the battery. A bidirectional power conversion module is adopted. The power consumption unit end is a single-phase single power interface, and the output is electricity with unified carbon emissions. The carbon emission data is obtained by the BMS through real-time calculation and processing of the carbon emissions of the input source and is statistically calculated for each power consumption unit. For power consumption units that can work intermittently, the BMS can start and stop the power consumption units through switches or communication methods to match the coordination of different carbon emission targets and power states and achieve carbon emission compliance.

[0108] Through the above methods, the BMS can realize the real-time monitoring of the carbon emission status of the charging equipment and the progress of meeting the carbon emission targets of the power consumption units, and the real-time statistics of the carbon emission status of the electric energy in the battery. Thus, it can adjust the power matching relationship between the charging equipment, the power consumption unit, and the battery module in real time. At the same time, it can also manage multiple charging equipment and power consumption units by using a switch matrix or a power conversion module. Based on this, through the carbon emission management of the charging equipment and the power consumption unit by the BMS, and the control of the real-time charge and discharge of the battery, the carbon emission management in the process of energy flow is realized. By reasonably allocating the power and duration of different carbon emission management targets at the input and output ends, the optimal solution for the carbon emissions of the electric energy of the power consumption unit is provided, and the optimal carbon emission energy utilization is effectively realized.
