Technical Field

[0001] The present invention relates to the field of source-grid-load-storage technology, and specifically refers to a source-grid-storage-charging-switch integrated device based on local green electricity. Background Art

[0002] Against the backdrop of the current energy structure transformation and technological progress, the use of integrated power grid and storage (integrated power grid, load and storage) and green electricity (green electricity) are becoming the key to promoting the efficient use of renewable energy. Integrated power grid and storage technology achieves optimal allocation and efficient management of energy by integrating power generation, transmission, storage and consumption, while green electricity represents the widespread application of clean energy such as wind and solar energy. Together, they support a low-carbon, environmentally friendly energy future. However, existing technologies have some challenges and defects in the integrated application of integrated power grid and storage and green electricity, especially in the charging and swapping management of energy storage batteries.

[0003] For example, an important problem faced by existing integrated charging and swapping devices when charging and swapping energy storage batteries is the lack of real-time response and adjustment capabilities to changes in battery status. During the charging and swapping process, key parameters such as battery voltage, current and temperature will change. However, in actual applications, it is difficult for existing devices to monitor the status of energy storage batteries after charging and swapping in real time, so that it is impossible to obtain the charging demand parameters of the energy storage batteries after charging and swapping in time, making it difficult to optimize the charging process, which may cause damage to the battery, thereby affecting the service life and safety of the energy storage battery and limiting the use of the device. Summary of the invention

[0004] The purpose of the present invention is to provide a source-grid integrated storage-charging-swap device based on local green electricity, which is used to solve one of the above-mentioned problems existing in the prior art.

[0005] Specifically, the present invention is achieved through the following technical solutions: A source-grid-storage-charging-switchable integrated device based on local green electricity, comprising a power supply side, a grid side, an energy storage side and a user load side, wherein the power supply side generates electricity based on a wind and solar power generation unit to generate green electricity and outputs it to the grid side; the grid side transmits the green electricity to the user load side and the energy storage side based on a transmission network, and the user load side is an electricity terminal; the energy storage side is used to store the surplus electricity transmitted by the grid side and consumed by the user load side, and dynamically supply power to the user load side based on the power consumption demand of the user load side, and the energy storage side also includes: The packaging shell is fixedly arranged and has a cavity inside, and the two sides inside the cavity are divided into a charging area and a battery replacement area; The storage and charging unit includes a plurality of energy storage batteries located in the charging area and installed on a charging rack in the charging area, wherein the charging rack is provided with a plurality of charging slots corresponding to the energy storage batteries from top to bottom, and the plurality of energy storage batteries are correspondingly inserted in the charging slots and connected to the charging modules in the charging slots, and the charging modules are connected to the grid side through lines; The battery replacement mechanism is arranged in the battery replacement area, and completes the battery replacement work by grabbing and replacing the energy storage battery on the charging rack. A battery replacement door is provided on one side of the battery replacement area, and the energy storage battery that has been grabbed and replaced can be taken out through the battery replacement door; The dynamic adjustment unit is arranged in the charging area, and includes a monitoring module and an adjustment module. The monitoring module is used to collect state change data of the energy storage battery during charging and replacing, and transmit it to the data processor located at the upper part of the charging area for processing to output the charging requirement parameters of the energy storage battery after the current replacement. After receiving the charging requirement parameters of the current energy storage battery output by the data processor, the adjustment module performs feedback adjustment on the charging parameters of the charging module of the corresponding energy storage battery in real time.

[0006] It should be noted that this solution, by introducing a dynamic adjustment unit, including a monitoring module and an adjustment module, can collect real-time data on state changes of the energy storage battery during charging and swapping, and output the charging requirement parameters of the energy storage battery after the current swap. This effectively solves the technical problem that the prior art cannot obtain the charging requirement parameters of the energy storage battery after charging and swapping in a timely manner, which makes it difficult to optimize the charging process and may cause damage to the battery. This greatly improves the use effect and life of the energy storage battery and greatly improves the use effect of the device. At the same time, it can more accurately evaluate the battery condition, provide more reasonable charging parameters for the charging module, achieve precise control of the energy storage battery, and effectively improve the integrated application performance and reliability of source-grid storage and green electricity technology.

[0007] Specifically, the monitoring module is arranged in several charging slots respectively, and collects the state change data of the energy storage battery in the charging slot during charging and swapping. The monitoring module includes a temperature sensor, a current sensor and a voltage sensor. The temperature sensor is installed on the side wall of the charging slot, and the temperature measuring part at one end is close to the energy storage battery, which is used to collect the temperature change data of the energy storage battery during charging and swapping. The current sensor and voltage sensor are integrated on the charging module in the charging slot, which are used to collect the current change data and voltage change data of the charging module when the energy storage battery is charged and swapped.

[0008] The data processor is respectively connected to the temperature sensor, the current sensor and the voltage sensor signals, and performs calculation processing on the temperature change data, the current change data and the voltage change data collected by the temperature sensor, the current sensor and the voltage sensor after receiving the temperature change data, the current change data and the voltage change data. The calculation processing process of the data processor includes: Step 1: synchronize the timestamps of the received temperature change data, current change data, and voltage change data, and process them for consistency by cleaning, deduplication, and format conversion; Step 2, sampling and aligning the temperature change data, current change data and voltage change data after consistency processing in step 1; Step 3, using a weighted average algorithm to perform feature data fusion processing on the temperature change data, current change data, and voltage change data after sampling alignment, and output a unified feature data collection; Step 4: Calculate and process the feature data collection through the energy storage battery charging evaluation model, and evaluate the status parameters of the energy storage battery currently in the charging and swapping state, and then calculate and output the charging demand parameters of the current energy storage battery based on the status parameters of the energy storage battery currently in the charging and swapping state.

[0009] Specifically, in step 3, the feature data fusion process satisfies the following calculation process: ;in, Indicates at a point in time Temperature change data, Indicates at a point in time Current change data, Indicates at a point in time Voltage change data, , , Respectively represent the weights of temperature change data, current change data and voltage change data, represents the total number of time points, Represents the output feature data collection.

[0010] Preferably, in step 4, the energy storage battery charging evaluation model is constructed based on a Gaussian process regression model, and the Gaussian process regression model includes a feature input layer, a kernel function calculation layer and a result output layer; The feature input layer is used to extract dynamically changing data source points in the feature data collection as model input to the kernel function calculation layer; The kernel function calculation layer defines the similarity measurement of the dynamically changing data source points based on the dynamically changing data source points as the model input, and calculates and infers the dependency output between the dynamically changing data feature points by constructing a covariance matrix, and then iteratively calculates the posterior probability distribution of the condition parameters of the energy storage battery currently in the charging and swapping state based on the dependency between the dynamically changing data feature points calculated and output by the covariance matrix, and matches and compares the calculated posterior probability distribution of the condition parameters with the expected threshold value, so as to evaluate and obtain the condition parameters of the energy storage battery currently in the charging and swapping state and output them; After the result output layer receives the status parameters of the energy storage battery currently in the charging and swapping state output by the kernel function calculation layer, it comprehensively calculates the charging requirement parameters of the energy storage battery currently in the charging and swapping state based on the energy storage battery status parameters and the charging rate requirements and outputs them.

[0011] In the above scheme, the dynamic adjustment unit is the core of this scheme. It monitors the state changes of the energy storage battery in the charging and swapping process in real time, and dynamically adjusts the charging parameters according to these changes to optimize the battery's use effect and life. Specifically, the monitoring module in the dynamic adjustment unit includes a temperature sensor, a current sensor and a voltage sensor installed in the charging slot, so that it can collect the temperature change data, current change data and voltage change data of the energy storage battery in real time during the charging and swapping process, and transmit the collected data to the data processor. The data processor first synchronizes the timestamp of the received data to ensure that all data points are consistent in time. Then, the data is processed for consistency through cleaning, deduplication and format conversion to eliminate noise and outliers, and unify data of different formats into the same format. The preprocessed data enters the feature data fusion processing stage, and the weighted average algorithm is used to fuse the sampled and aligned data to form a unified feature data collection (it should be further explained that during the data fusion processing, a comprehensive weighted average is calculated by comprehensively considering the importance of temperature, current and voltage data (that is, weights) to accurately reflect the current state of the battery). The obtained feature data collection is then applied to the charging evaluation model, which is built based on the Gaussian process regression algorithm. It analyzes dynamically changing data source points, defines the similarity measure between data points, constructs a covariance matrix, and calculates the posterior probability distribution to evaluate the status parameters of the energy storage battery under the current charging and swapping state, and obtains the charging demand parameters of the energy storage battery under the current charging and swapping state based on the status parameters. Finally, the adjustment module feeds back and adjusts the charging parameters of the charging module in real time according to the charging demand parameters output by the data processor. This may include adjusting the charging current, voltage or charging strategy to ensure that the battery is charged in the optimal state, avoiding overcharging or undercharging, thereby extending the life of the energy storage battery and improving charging efficiency.

[0012] Compared with the prior art, the present invention has the following advantages and beneficial effects: 1. The present invention introduces a dynamic adjustment unit, including a monitoring module and an adjustment module, which can collect the state change data of the energy storage battery during charging and replacement in real time, and output the charging demand parameters of the energy storage battery after the current replacement. It solves the problem that the charging parameters cannot be adjusted in real time in the prior art, thereby improving the use effect and life of the energy storage battery. At the same time, by adopting a weighted average algorithm and a Gaussian process regression model, it can more accurately evaluate the battery status, provide more reasonable charging parameters for the charging module, and achieve precise control of the energy storage battery, effectively improve the integrated application performance and reliability of source-grid storage and green electricity technology, and optimize the charging process, thereby improving the charging efficiency and service life of the device; 2. The present invention provides dual physical protection for the charging connector by providing a charging terminal housing and a plug ring. The charging terminal housing is located on the side wall of the charging slot, which can resist external impact and damage and protect the charging connector from physical damage. The plug ring is sleeved on the outside of the docking rod, which further enhances the wear resistance and impact resistance of the docking rod, effectively preventing damage to the docking rod in daily use and extending the service life of the charging module. Furthermore, in the annular gap formed between the plug ring and the docking rod, a plurality of cleaning nozzles distributed in a circular array are provided at the corresponding charging interface position. When the charging plug rod is inserted into the charging interface, the extrusion portion at its front end is interference fit with the sealing gasket, squeezing the inflatable bag in the sealing gasket, so that the gas inside the inflatable bag enters the cleaning nozzle through the gas pipeline and is ejected from the nozzle to purge the charging interface. This automatic dust cleaning mechanism can timely remove dust and impurities at the charging interface, keep the charging contact surface clean, and thus improve charging efficiency and reliability. In addition, a sealing gasket is provided on the inner ring surface of the plug ring near its end, and an air bag is provided inside the sealing gasket. The design of the air bag not only provides an additional sealing effect to prevent dust and moisture from invading the charging interface, but also provides a stable support and buffer for the charging rod through the elastic effect of the air bag, ensuring a close fit between the charging rod and the charging interface, and enhancing the stability and reliability of the charging connection. 3. The present invention symmetrically arranges support plates on both sides of the charging slot, and opens guide grooves on the support plates. These guide grooves are arranged along the length direction of the support plates, and are connected to the outside at one end, and a blocking baffle is provided at the other end, thereby ensuring the accurate guidance and positioning of the energy storage battery during the installation process. At the same time, a plurality of guide rollers are arranged in an array in the guide groove, so that the grabbing structure can move more smoothly when grabbing the energy storage battery for charging and replacing. Furthermore, in this solution, after the energy storage battery is installed in place, the plug connector at one end of the clamping block is inserted into the plug slot, and a magnetic connection is achieved through the connecting piece and the magnetic suction piece at the middle position of the slot bottom, and then the energy storage battery is charged and replaced. The plug connector is provided with a stable magnetic attraction force, and the wedge-shaped inclined surfaces on both sides of the plug connector guide and cooperate with the top block in the cavity. That is, in the process of gradual insertion of the plug connector, the plug connector can lift the top block through the wedge-shaped inclined surfaces on both sides of the plug connector, thereby prompting the top block to move under the guidance of the plug connector, so as to push the flip plate in the cavity to flip, and then the flipping action of the flip plate drives the limit card block to be inserted into the limit groove at the other end of the card block to complete the limit fixation of the card block, thereby promoting the stable installation of the energy storage battery, to ensure that the energy storage battery is installed and fixed, to avoid displacement, and then affecting the normal charging and replacement of the energy storage battery.

[0015] The technical solution of the present invention is further described in detail below in conjunction with the accompanying drawings, but the protection scope of the present invention is not limited to the following.

[0016] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention is further described in detail in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention, that is, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[0017] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention claimed for protection, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of the present invention.

[0018] The features and performance of the present invention are further described in detail below in conjunction with the embodiments.

[0019] Example Please refer to the attached Figure 1 to Figure 2This embodiment provides a source-grid-storage-charging-swap device based on local green electricity, including a power supply side, a grid side, an energy storage side and a user load side. The power supply side generates electricity based on a wind and solar power generation unit to generate green electricity, and outputs it to the grid side; the grid side transmits the green electricity to the user load side and the energy storage side based on the transmission network, and the user load side is an electricity terminal; the energy storage side is used to store the surplus electricity transmitted by the grid side and consumed by the user load side, and dynamically supply power to the user load side based on the power consumption demand of the user load side. The energy storage side also includes: The packaging shell 1 is fixedly arranged and has a cavity 117 inside. The two sides inside the cavity 117 are divided into a charging area 11 and a battery replacement area 10; The storage and charging unit includes a plurality of energy storage batteries 111 located in the charging area 11 and installed on a charging rack 110 in the charging area 11. The charging rack 110 is provided with a plurality of charging slots corresponding to the energy storage batteries 111 from top to bottom. The plurality of energy storage batteries 111 are correspondingly inserted in the charging slots and connected to the charging modules 112 in the charging slots. The charging modules 112 are connected to the grid side through lines. The battery replacement mechanism 100 is arranged in the battery replacement area 10, and completes the battery replacement work by grabbing and replacing the energy storage battery 111 on the charging rack 110. A battery replacement door 12 is provided on one side of the battery replacement area 10, and the energy storage battery 111 that has been grabbed and replaced can be taken out through the battery replacement door 12; The dynamic adjustment unit is arranged in the charging area 11, and includes a monitoring module and an adjustment module. The monitoring module is used to collect state change data of the energy storage battery 111 during charging and replacement, and transmit it to the data processor 23 located at the upper part of the charging area 11 for processing to output the charging requirement parameters of the energy storage battery 111 after the current replacement. After receiving the charging requirement parameters of the current energy storage battery 111 output by the data processor 23, the adjustment module performs feedback adjustment on the charging parameters of the charging module 112 corresponding to the energy storage battery 111 in real time.

[0020] It should be understood that in the prior art, due to slight differences in the manufacturing and use of the energy storage battery 111, these differences will gradually accumulate in the long-term charge and discharge cycle, resulting in inconsistency in the performance of the energy storage battery 111. If no dynamic adjustment is performed, this inconsistency will cause some of the energy storage batteries 111 to be overcharged or over-discharged, thereby accelerating the aging of the energy storage battery 111, reducing the performance and service life of the energy storage battery 111, and increasing safety hazards, such as the risk of thermal runaway caused by local overheating; at the same time, the fluctuation of the grid load requires the energy storage side to respond quickly to maintain the stability of the grid. If the energy storage side cannot dynamically adjust the charging parameters according to the real-time demand of the grid and the battery status, it will lead to energy waste and low efficiency, and it will not be able to effectively balance the grid load, affecting the reliability of power supply.

[0021] Therefore, the dynamic adjustment unit of this embodiment can monitor the battery status in real time and dynamically adjust the charging parameters according to the data, which plays a vital role in maintaining the health of the battery, improving energy utilization efficiency, and ensuring the stability and safety of the power grid. It can optimize the charging and discharging process, reduce battery stress, and extend the life of the energy storage battery 111. At the same time, it improves the adaptability and response speed of the energy storage side to changes in the power grid, ensuring the continuity and reliability of power supply.

[0022] Specifically, if Figure 3 As shown, the monitoring module is correspondingly arranged in a plurality of charging slots, and collects state change data of the energy storage battery 111 in the charging slot during charging and swapping. The monitoring module includes a temperature sensor 20, a current sensor 21 and a voltage sensor 22. The temperature sensor 20 is installed on the side wall of the charging slot, and a temperature measuring portion at one end thereof is close to the energy storage battery 111, and is used to collect temperature change data of the energy storage battery 111 during charging and swapping. The current sensor 21 and the voltage sensor 22 are integrated on the charging module 112 in the charging slot, and are used to collect current change data and voltage change data of the charging module 112 when the energy storage battery 111 is charged and swapped.

[0023] For this embodiment, the temperature change data, current and voltage change data are crucial for evaluating the health status and charging efficiency of the battery, because temperature monitoring is crucial for preventing battery overheating and thermal runaway, because the battery generates heat during the charging and discharging process, and improper temperature control may cause the performance of the energy storage battery 111 to degrade or even be damaged, while the current and voltage change data are crucial for evaluating the health status and charging efficiency of the battery, which can accurately indicate the performance state changes inside the battery. Therefore, in this embodiment, in order to facilitate real-time monitoring of the key parameters of the energy storage battery 111, the monitoring module (including the temperature sensor 20, the current sensor 21 and the voltage sensor 22) is respectively installed in the charging slot, so as to facilitate real-time monitoring and collection of relevant key parameters of the energy storage battery 111, so as to facilitate the evaluation and analysis of the state of the energy storage battery 111 during charging and replacement, and then facilitate accurate control and optimization of the energy storage battery 111 during charging and replacement, thereby improving the safety and efficiency of the energy storage side, and ensuring the safe use of the device and extending its life.

[0024] Based on the above embodiment, the data processor 23 is respectively connected to the temperature sensor 20, the current sensor 21 and the voltage sensor 22, and performs calculation processing on the temperature change data, the current change data and the voltage change data collected by the temperature sensor 20, the current sensor 21 and the voltage sensor 22 after receiving the temperature change data, the current change data and the voltage change data. The calculation processing process of the data processor 23 includes: Step 1: synchronize the timestamps of the received temperature change data, current change data, and voltage change data, and process them for consistency by cleaning, deduplication, and format conversion; Step 2, sampling and aligning the temperature change data, current change data and voltage change data after consistency processing in step 1; Step 3, using a weighted average algorithm to perform feature data fusion processing on the temperature change data, current change data, and voltage change data after sampling alignment, and output a unified feature data collection; Step 4, calculate and process the feature data collection through the energy storage battery 111 charging evaluation model, and evaluate the status parameters of the energy storage battery 111 currently in the charging and swapping state, and then calculate and output the charging demand parameters of the current energy storage battery 111 based on the status parameters of the energy storage battery 111 currently in the charging and swapping state.

[0025] It should be shown that this embodiment realizes accurate monitoring and optimized management of the charging and swapping status of the energy storage battery 111 through a sophisticated data processor 23 workflow. The data processor 23 is first connected to the temperature sensor 20, the current sensor 21, and the voltage sensor 22 to ensure that the key parameters of the energy storage battery 111 during the charging and swapping process can be fully collected. Specifically, the technical solution disclosed in this embodiment significantly improves the battery performance and the efficiency of the energy storage side through a series of innovative data preprocessing and analysis technologies. First, the data processor 23 ensures the temporal consistency of data collected from different sensors through timestamp synchronization technology, which is a prerequisite for data fusion. Then, data cleaning and format conversion technology are used to eliminate noise and outliers, and unify data in different formats for subsequent processing. This step not only improves the quality of the data, but also provides an accurate data basis for feature extraction and model training. After sampling alignment, a weighted average algorithm is used to perform feature data fusion processing on the data. This algorithm takes into account the accuracy and importance of different sensor data, and optimizes the data fusion results by assigning different weights, thereby outputting a unified feature data collection. In addition, in this embodiment, the energy storage battery 111 charging evaluation model is used to evaluate the energy storage battery 111 when it is charged and replaced, which can provide probability prediction and uncertainty estimation, which is particularly important for battery health management and predictive maintenance. It enhances the accuracy and reliability of the state evaluation of the energy storage battery 111, and can calculate the charging demand parameters of the energy storage battery 111 to dynamically adjust the charging strategy to avoid overcharging or undercharging, reduce damage to the energy storage battery 111, and thus improve the use efficiency and life of the energy storage battery 111.

[0026] Furthermore, based on the above embodiment, in step 3, the feature data fusion processing satisfies the following calculation process: ;in, Indicates at a point in time Temperature change data, Indicates at a point in time Current change data, Indicates at a point in time Voltage change data, , , Respectively represent the weights of temperature change data, current change data and voltage change data (it should be noted that the weight setting is based on the importance and reliability of each parameter on the battery status, and when allocating specific weights, it can be adjusted according to the importance of each data source on the battery status). represents the total number of time points, Represents the output feature data collection.

[0027] It should be noted that the weighted average algorithm in the above embodiment can more accurately evaluate the state of the energy storage battery 111. Specifically, it can be dynamically adjusted according to the characteristics and importance of different data, so as to achieve higher accuracy and efficiency in the data fusion process, thereby providing more accurate input data for the charging evaluation model, and then calculating more reasonable charging demand parameters, optimizing the charging process, so as to improve the use efficiency and life of the energy storage battery 111.

[0028] As a preferred implementation scheme, in step 4, the energy storage battery 111 charging evaluation model is constructed based on a Gaussian process regression model, and the Gaussian process regression model includes a feature input layer, a kernel function calculation layer and a result output layer; The feature input layer is used to extract dynamically changing data source points in the feature data collection as model input to the kernel function calculation layer; The kernel function calculation layer defines the similarity measurement of the dynamically changing data source points based on the dynamically changing data source points as the model input, and calculates and infers the dependency relationship between the dynamically changing data feature points by constructing a covariance matrix to output, and then iteratively calculates the posterior probability distribution of the status parameters of the energy storage battery 111 currently in the charging and swapping state based on the dependency relationship between the dynamically changing data feature points calculated and output by the covariance matrix, and matches and compares the calculated posterior probability distribution of the status parameters with the expected threshold value to evaluate and obtain the status parameters of the energy storage battery 111 currently in the charging and swapping state and output them; After the result output layer receives the status parameters of the energy storage battery 111 currently in the charging and swapping state output by the kernel function calculation layer, it comprehensively calculates the charging requirement parameters of the energy storage battery 111 currently in the charging and swapping state based on the status parameters of the energy storage battery 111 and the charging rate requirement and outputs them.

[0029] It should be noted that in this embodiment, a Gaussian process regression model is used to construct a charging evaluation model for the energy storage battery 111. The model includes a feature input layer, a kernel function calculation layer and a result output layer. The feature input layer extracts dynamically changing data source points in the feature data collection. The kernel function calculation layer defines a similarity measure based on these data source points, and calculates the dependency between the dynamically changing data feature points by constructing a covariance matrix. This process not only provides a probabilistic prediction of the battery state, but also quantifies the uncertainty of the prediction. After the result output layer receives the battery state parameters output by the kernel function calculation layer, it comprehensively calculates the charging demand parameters based on these parameters and the charging rate requirement and outputs them, so that the state change of the energy storage battery 111 can be predicted more accurately, thereby dynamically adjusting the charging strategy, avoiding overcharging or undercharging, reducing damage to the energy storage battery 111, and improving the use efficiency and life of the energy storage battery 111.

[0030] It should also be noted that this solution is used for charging evaluation of energy storage battery 111 through Gaussian process regression model, which can handle uncertainty and nonlinear problems. By defining similarity metrics between data points and constructing covariance matrices, it provides a powerful tool to evaluate battery condition parameters. Compared with traditional machine learning methods, it can provide probabilistic prediction and uncertainty estimation, which is particularly important for battery health management and predictive maintenance. In other words, the technical solution disclosed in this embodiment comprehensively applies advanced technologies such as timestamp synchronization, data cleaning, feature data fusion and Gaussian process regression model, which not only improves the accuracy and efficiency of data processing, but also enhances the accuracy and reliability of state evaluation of energy storage battery 111. It can dynamically adjust the charging strategy to avoid overcharging or undercharging, reduce damage to energy storage battery 111, and thus improve the use efficiency and life of energy storage battery 111.

[0031] Based on the above embodiments, please refer to Figure 3The charging module 112 includes a charging terminal housing 1120 and a charging connector. The charging terminal housing 1120 is located on the side wall of the charging slot. The charging connector is installed on a side of the charging terminal housing 1120 corresponding to the energy storage battery 111. The charging connector includes a protruding docking rod 1121 and a charging interface 11210 opened at one end of the docking rod 1121. A protection component is also provided around the docking rod 1121 near the charging interface 11210. The protection component includes a plug ring 1121 sleeved on the outside of the docking rod 1121. 2, and one end of the plug-in ring 1122 is closer to the energy storage battery 111 than the end of the docking rod 1121, and an annular gap is formed between the inside of the plug-in ring 1122 and the docking rod 1121, and a plurality of cleaning nozzles 1123 distributed in an annular array are provided in the gap at the position corresponding to the charging interface 11210, and a sealing gasket 1124 is also provided on the inner ring surface of the plug-in ring 1122 near its end position, and an inflatable bag 1125 is provided inside the sealing gasket 1124, and the inflatable bag 1125 is connected to the cleaning nozzle 1123 through an air pipeline.

[0032] It should be understood that when used for a long time, the charging interface 11210 is exposed to the external environment for a long time, and dust and debris will inevitably adhere to it.
