[0002] Battery-powered devices are increasingly popular among users due to their environmental and clean nature. With the advancement of lithium-ion battery technology, battery-powered devices are becoming increasingly widely used, and users are increasingly demanding charging management for these devices. In real-world scenarios, devices often remain unused for extended periods. During long-term storage, excessive or low battery levels can affect battery life and performance. Therefore, battery charge management is essential for devices that are not in use for extended periods.

[0071] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0072] Electric tools are environmentally friendly and clean, and compared to fuel-powered tools, they also produce relatively little noise. Therefore, electric tools are increasingly popular among power tool users. Electric gardening tools are widely used in tasks such as lawn mowing, landscaping, and garden maintenance. Large-scale outdoor operations are often completed by gardening teams consisting of multiple operators, who often carry multiple electric gardening tools. Since electric gardening tools are powered by battery packs, their battery life is often short. Therefore, to improve work efficiency in outdoor operations, gardening teams often equip themselves with battery packs and charging equipment in addition to their electric gardening tools. The charging equipment is used to charge the battery packs. Lithium batteries are typically recharged by using a charger to convert mains electricity into DC power. However, mains electricity is difficult to obtain when gardening teams are working outdoors, making charging difficult. Therefore, the charging equipment should preferably include a DC battery module, eliminating the need for AC power to charge the battery packs. This can address the technical issue of limited battery charging during outdoor operations caused by the lack of mains electricity. In actual application scenarios, energy devices including charging equipment for DC battery modules and battery packs are often not needed for long periods of time. During long-term storage, excessive or low battery charge will affect the battery life and performance.

[0073] In order to solve the technical problem that when a charging device is not used for a long time, the battery life and performance of the battery will be affected by either too high or too low battery level. The present invention provides a charging device that controls its DC battery module to charge to a set power value and then stops charging when receiving a long-storage charging instruction. This can effectively extend the life of the DC battery module and prevent performance degradation of the DC battery module.

[0074] As shown in Figures 1 and 9, an embodiment of the present application provides a charging device 20 (also referred to as a long storage device), including a shell, a built-in battery module 200 (also referred to as a built-in battery pack) and a control module 201 arranged in the shell, as well as a wireless communication module 202 (also referred to as a communication module) and a power input terminal 203. The power input terminal 203 is used to connect an external power supply to charge the built-in battery module 200. The control module 201 is electrically connected to the wireless communication module 202 and can communicate with the user terminal 30 (also referred to as a mobile terminal) through the wireless communication module 202. The control module 201 is configured as follows: the control module 201 receives a long-storage charging instruction (also referred to as a device long-storage instruction) sent by a user terminal via the wireless communication module 202, and controls the charging device 20 to activate a long-storage charging mode (i.e., activate long-storage) according to the long-storage charging instruction. In the long-storage charging mode, when the charging device 20 is connected to an external power source, the control module 201 obtains the remaining power of the internal battery module 200 and compares the remaining power of the internal battery module 200 with a battery module long-storage power value (also referred to as a long-storage power setting value or a battery module long-storage power setting value). When the remaining power of the internal battery module 200 falls below the battery module long-storage power value, the control module 201 controls the internal battery module 200 to charge to a battery module stop power value and then stops charging. The battery module stop power value is set to a battery module offset ΔR (also referred to as a battery module set offset ΔR or a battery module set offset value ΔR) relative to the battery module long-storage power value, where -50%*battery module long-storage power value ≤ battery module offset ΔR ≤ 50%*battery module long-storage power value.

[0075] Furthermore, the wireless communication module 202 can be configured as a 3G module, a 4G module, a 5G module, a LoRa module, a Sigfox module, or a NB-IoT module. Preferably, in this embodiment, the wireless communication module 202 is configured as a 4G module. The control module 201 is provided with a communication interface, and the control module 201 is electrically connected to the wireless communication module 202 via the communication interface. The control module 201 can achieve remote communication with the user terminal 30 through the wireless communication module 202, thereby enabling data exchange with the user terminal 30.

[0076] For the sake of convenience of description, the process of "the control module 201 obtains the remaining power value of the built-in battery module 200, and compares the remaining power value of the built-in battery module 200 with the long storage power value of the battery module, and when the remaining power value of the built-in battery module 200 is lower than the long storage power value of the battery module, controls the built-in battery module 200 to charge to the battery module stop power value and then stops charging" is defined as the control module 201 executing the battery module long storage charging strategy.

[0077] Based on this, the user can send a long-storage charging instruction to the charging device 20 through the user terminal. After the control module 201 in the charging device 20 receives the long-storage charging instruction sent by the user terminal through the wireless communication module 202, it controls the charging device 20 to enter the long-storage charging mode according to the long-storage charging instruction. In the long-storage charging mode, when the charging device 20 is connected to an external power source, the control module 201 directly executes the battery module long-storage charging strategy, which can meet the user's needs for long-storage charging management of the charging device 20. It is understandable that in the long-storage charging mode, if the charging device 20 is currently not connected to an external power source, the control module 201 will only execute the battery module long-storage charging strategy when the charging device 20 is connected to an external power source.

[0078] When it comes to long-term storage charging management, when a user decides to enable long-term storage charging mode on a charging device 20, they are often not at the charging site of the charging device 20. The charging device 20 may be in use and disconnected from an external power source. If the user needs to control the long-term storage charging mode on the charging device 20, they can only control the long-term storage charging mode on the charging device 20 at the charging site after using the charging device 20. Furthermore, the user may forget to enable the long-term storage charging mode on the charging device 20 at the charging site, making long-term storage charging management of the charging device 20 very inconvenient.

[0079] In this embodiment, since the user can send a long-storage charging instruction to the charging device 20 through the user terminal 30, remote long-storage charging management of the charging device 20 can be achieved. The user does not need to operate at the charging site and can send a long-storage charging instruction through the user terminal at any time. For example, the user can send a long-storage charging instruction through the user terminal when the charging device 20 is not connected to an external power supply. After receiving the long-storage charging instruction, the control module 201 of the charging device 20 will execute the long-storage charging strategy when the charging device 20 is connected to an external power supply, which can meet the user's needs for long-storage charging management of the charging device 20 at any time and any place. That is, the user can immediately send a long-storage charging instruction through the user terminal when he thinks that the charging device 20 needs to turn on the long-storage charging mode, which can avoid forgetting to turn on the long-storage charging mode of the charging device 20.

[0080] It should be noted that the long storage capacity value of the battery module can be a point value or a range. Preferably, in this embodiment, the long storage capacity value of the battery module is a point value.

[0081] In other embodiments, in certain scenarios, users may not have precise requirements for the battery capacity of the internal battery module during long-term storage. For example, the optimal long-term storage capacity of the internal battery module is 40% of its battery capacity, but when its capacity is between 30% and 50% of its battery capacity, it is considered to meet the long-term storage requirement. In this case, the battery module long-term storage capacity can be set to 30% to 50% of the battery capacity, and the battery module shutdown capacity can be set to 40% of the battery capacity, thereby meeting the user's long-term storage requirement. Specifically, the remaining capacity of the internal battery module 200 is determined to be within the range of 30% to 50% of the battery capacity. If the remaining capacity of the internal battery module 200 is not within this range, the internal battery module 200 is controlled to charge or discharge to 40% of the battery capacity and then stop. Otherwise, no charging or discharging is required to meet the user's long-term storage requirement. It is understandable that, on the contrary, the long-term storage capacity value of the battery module is set to a point value, which can meet the user's precise requirements for the capacity value of the built-in battery module during long-term storage.

[0082] Furthermore, when the battery module long storage capacity value is a point value, the battery module long storage capacity value and the battery module stop capacity value can be the same value or different values. Preferably, in this embodiment, the battery module long storage capacity value and the battery module stop capacity value are equal.

[0083] In other embodiments, in certain scenarios, the user may not have precise requirements for the internal battery module's long-term storage capacity. For example, the optimal long-term storage capacity of the internal battery module is 40% of its battery capacity, but when its capacity is between 30% and 40% of its battery capacity, it is considered to meet the internal battery module's long-term storage requirement. In this case, the battery module long-term storage capacity can be set to 30% of the internal battery module's battery capacity, while the battery module shutdown capacity can be set to 40% of the internal battery module's battery capacity (i.e., the battery module shutdown capacity is offset from the battery module long-term storage capacity by a battery module offset ΔR of 10% of the internal battery module's battery capacity). This will meet the user's long-term storage requirement for the internal battery module. It will be appreciated that, conversely, the battery module long-term storage capacity and the battery module shutdown capacity can be equal, which can meet the user's precise requirements for the internal battery module's long-term storage capacity. Therefore, the battery module long-term storage capacity and the battery module shutdown capacity can be set to be the same or different based on the user's requirements for long-term storage capacity accuracy, and the size of the battery module offset ΔR can be adjusted based on the accuracy requirements.

[0084] It is understandable that by lowering the requirements for the accuracy of long-term storage power, battery modules with power within a certain range do not need to be charged for long-term storage, which can effectively reduce the long-term storage charging operations of built-in battery modules and alleviate the shortage of equipment, resources and personnel to a certain extent.

[0085] In one embodiment of the present invention, as shown in Figures 4 and 9, the charging device 20 also includes at least one charging interface 205 provided on the shell, the charging interface 205 is used to connect to the battery pack, the built-in battery module 200 is electrically connected to the charging interface 205 to output electrical energy through the charging interface 205 to charge the battery pack, and the control module 201 can communicate with the battery pack.

[0086] In the long-storage charging mode, the control module 201 obtains the remaining power value of the battery pack when the charging interface 205 is connected to the battery pack, and compares the remaining power value of the battery pack with the long-storage power value of the battery pack (also referred to as the long-storage set power value of the battery pack). When the remaining power value of the battery pack is lower than the long-storage power value of the battery pack, the battery pack is controlled to charge to the battery pack stop power value and then stops charging. The battery pack stop power value G′ is set to be offset by the battery pack offset ΔS (also referred to as the battery pack set offset ΔS) relative to the battery pack long-storage power value G, where -50%*battery pack long-storage power value ≤ battery pack offset ΔS ≤ 50%*battery pack long-storage power value, that is, G′=G+ΔS, -50%*G≤ΔS≤50%*G.

[0087] For ease of description, the process of "the control module 201 obtains the remaining power value of the battery pack, and compares the remaining power value of the battery pack with the long storage power value of the battery pack, and when the remaining power value of the battery pack is lower than the long storage power value of the battery pack, controls the battery pack to charge to the battery pack stop power value and then stops charging" is defined as the control module 201 executing the battery pack long storage charging strategy.

[0088] Based on this, the charging device 20 can not only manage long-term storage charging for its internal battery module 200, but also manage the charging of a battery pack connected to the charging device 20. In long-term storage charging mode, when a battery pack is connected to the charging port 205 of the charging device 20, the control module 201 directly executes the battery pack long-term storage charging strategy, meeting the user's need for long-term storage charging management of the battery pack connected to the charging device 20. It is understood that in long-term storage charging mode, if no battery pack is currently connected to the charging port of the charging device 20, the control module 201 will only execute the battery pack long-term storage charging strategy when a battery pack is connected to the charging port of the charging device 20.

[0089] Furthermore, the control module 201 of the charging device 20 communicates with the battery pack via wired communication.

[0090] As an example, as shown in FIG5 , the battery pack 10 and the charging device 20 are equipped with matching wired communication modules. When the battery pack 10 and the charging device 20 are connected, they exchange data via wired communication, allowing the control module 201 to obtain information such as the remaining charge value of the battery pack. Specifically, the charging device 20 is equipped with a first wired communication module 2022, and the battery pack 10 is equipped with a second wired communication module 101. The first wired communication module 2022 and the second wired communication module 101 can be connected to each other to enable communication between the battery pack 10 and the charging device 20. The first wired communication module 2022 and the second wired communication module 101 described in this embodiment can be either a serial communication module or a CAN communication module. Of course, other forms of wired transmission modules are also possible and fall within the scope of protection of the present invention without departing from the core concept of the present invention. Preferably, the first wired communication module 2022 and the second wired communication module 101 are serial communication modules and / or CAN communication modules.

[0091] It should be noted that the battery pack's long-term storage capacity value can be a point value or a range. Preferably, in this embodiment, the battery pack's long-term storage capacity value is a point value. Its specific application scenarios are similar to those of the aforementioned built-in battery module, and can be selectively set based on the user's requirements for long-term storage capacity accuracy. This will not be further elaborated here.

[0092] Furthermore, when the battery pack long storage capacity value is a point value, the battery pack long storage capacity value and the battery pack stop capacity value can be the same value or different values ​​(i.e., the battery pack stop capacity value is offset from the battery pack long storage capacity value by the battery pack offset ΔS). Preferably, in this embodiment, the battery pack long storage capacity value and the battery pack stop capacity value are equal. Its specific application scenario is similar to that of the aforementioned built-in battery module. It can be selectively set to be the same or different based on the user's requirements for the accuracy of the long storage capacity, and the battery pack offset size can be set according to the accuracy requirements. It will not be further described here.

[0093] This embodiment can be combined with the above-mentioned embodiment. When the charging device 20 receives the long-storage charging instruction, the charging device 20 turns on the long-storage charging mode. If the charging device 20 is connected to an external power supply at this time, the built-in battery module 200 can be charged in the long-storage charging mode; if the charging device 20 is not connected to an external power supply at this time, when the charging interface 205 of the charging device 20 is connected to the battery pack 10, the battery pack 10 can be charged in the long-storage charging mode through the built-in battery module 200.

[0094] It can be understood that the long storage capacity values ​​of the built-in battery module 200 and the battery pack 10 can be the same or different. For example, the long storage capacity values ​​of the built-in battery module 200 and the battery pack 10 can be configured to 40% of their respective battery capacities; or the long storage capacity value of the built-in battery module 200 can be configured to 30% of the battery capacity of the built-in battery module 200, and the long storage capacity value of the battery pack 10 can be configured to 40% of the battery capacity of the battery pack 10.

[0095] It can be understood that the long-storage charging management of the built-in battery module 200 and the battery pack 10 can be controlled by the same long-storage charging instruction, or can be controlled separately by two long-storage charging instructions, that is, when the charging device receives the long-storage charging instruction, it can simultaneously turn on the long-storage charging mode of the built-in battery module 200 and the battery pack 10; the long-storage charging instruction can also be distinguished between the long-storage charging instruction of the built-in battery module and the long-storage charging instruction of the battery pack, and when the corresponding instruction is received, only the corresponding device is controlled to turn on the long-storage charging mode.

[0096] In one embodiment of the present invention, as shown in FIG3 , the charging device 20 includes a charging module 204. The power input terminal 203 is electrically connected to the internal battery module 200 via the charging module 204. The charging module 204 is configured to convert the AC power input from the power input terminal 203 into DC power for charging the internal battery module 200. A control module 201 is electrically connected to the internal battery module 200 to obtain the remaining power of the internal battery module 200. The control module 201 is electrically connected to the charging module 204, which is in turn electrically connected to the internal battery module 200. The control module 201 controls the charging and discharging of the internal battery module 200 by controlling the charging module 204.

[0097] Of course, the present invention is not limited to this. In another embodiment, if the power input terminal 203 inputs direct current, the control module 201 and the power input terminal 203 can also be directly electrically connected to the built-in battery module 200, which will not be repeated here.

[0098] The internal battery module 200 can be electrically connected to the charging interface 205 via the charging module 204. The charging module 204 is configured to convert the DC power output by the internal battery module 200 into the DC power required for charging the battery pack based on the charging parameters of the battery pack connected to the charging interface 205, thereby charging the battery pack. Of course, the present invention is not limited to this embodiment. In another embodiment, the internal battery module 200 can also be directly electrically connected to the charging interface 205, which will not be further described here.

[0099] In one embodiment described above, as shown in FIG7 , the charging device 20 can be configured as an energy storage charging device (also referred to as an energy storage cabinet). Energy storage charging devices are typically used as portable charging power supplies and include at least one charging port for connecting to a battery pack. Its internal battery module 200 is used to provide electrical energy, which is output through the charging port to charge the battery pack connected to the charging port. It will be appreciated that by providing the internal battery module 210, the energy storage charging device 20 no longer relies on an AC power source for charging the battery pack 10, thereby meeting the power needs of gardening teams during outdoor operations. The battery pack 10 can be used to provide power for at least one electric gardening tool, which may include one or more of a lawn mower, a brush cutter, an edger, pruning shears, a high-pressure washer, a hair dryer, a chain saw, a push mower, a multi-tasking tool, and a sprayer. For example, the battery pack 10 may be a handheld battery pack 10a, a backpack battery pack 10b, or other forms.

[0100] Large-capacity battery modules are often expensive, and thus charging devices equipped with them are also expensive. Compared to lower-cost, smaller-capacity battery modules, their service life is of greater concern to users. Therefore, there is a greater need for long-term charging management of the internal battery module 200. However, existing technologies typically only address long-term charging management for independent battery modules used for external charging, such as removable batteries, while neglecting long-term charging management for the charging device itself, which incorporates a large-capacity battery module.

[0101] In one embodiment of the present invention, the battery capacity of the built-in battery module 200 is not less than 3kWh, the battery capacity of the battery pack 10 is not greater than 1kWh, the power input terminal 203 is an AC power input terminal, which is used to connect to an external AC power supply. The charging device 20 also includes a charging module 204, which is used to convert the AC power input from the AC power input terminal into DC power to charge the built-in battery module 10, and to convert the DC power output from the built-in battery module 10 into the DC power required for charging the battery pack according to the charging parameters of the battery pack connected to the charging interface 205, so as to charge the battery pack. The control module 201 is electrically connected to the charging module 204 and controls the charging module 204 to control the charging of the built-in battery module 200 and the battery pack connected to the charging interface.

[0102] In one embodiment, the battery capacity of the built-in battery module 200 is not less than 3kWh, and can be 3KWh, 4KWh, 5KWh, 6KWh, 7KWh, 8KWh, 9KWh, 10KWh, 12KWh, 15KWh, 18KWh or 20KWh. Preferably, the battery capacity of the built-in battery module 200 can be 5KWh or 7.7KWh. The power of the battery pack 10 is not greater than 1KWh. The battery pack 10 includes a plurality of battery cells, and the plurality of battery cells are connected in series and / or in parallel. The battery pack 10 may include a backpack battery pack and a handheld battery pack. The battery capacity of the backpack battery pack is between 0.5kWh and 0.6kWh. Preferably, the battery capacity of the backpack battery pack is 0.6kWh. The battery capacity of the handheld battery pack is between 0.15-0.25kWh. Preferably, the battery capacity of the handheld battery pack is 0.2kWh.

[0103] In one embodiment of the present invention, as shown in FIG6 , the charging module 204 may include a first charging module 2041 and a second charging module 2042. The first charging module 2041 is configured to convert the AC power input from the power input terminal 203 into DC power for charging the internal battery module 200, i.e., the first charging module 2041 is configured to implement an AC-DC conversion function. The second charging module 2042 is configured to convert the DC power output from the internal battery module 200 into the DC power required for charging the battery pack based on the charging parameters of the battery pack connected to the charging interface 205, thereby charging the battery pack, i.e., the second charging module 2042 is configured to implement a DC-DC conversion function.

[0104] The charging interface 205 may include a first charging interface 2051, a second charging interface 2052, and a third charging interface 2053. In one embodiment, the first charging interface 2051, the second charging interface 2052, and the third charging interface 2053 may be of the same type to charge multiple battery packs 10 of the same type. In another embodiment, at least two of the first charging interface 2051, the second charging interface 2052, and the third charging interface 2053 may be of different types to charge battery packs 10 of different types. Of course, the present invention is not limited to this. In another embodiment, the charging interface 205 may include two, four, or even more types of charging interfaces, which will not be further described here.

[0105] In one embodiment, as shown in Figure 7, taking the charging device 20 as an energy storage charging device as an example, the charging device 20 includes a battery cabinet 210 and a charging cabinet 220, the built-in battery module 200 is arranged in the battery cabinet 210, and the charging cabinet 220 includes a first charging interface 2051, a second charging interface 2052 and a third charging interface 2053, wherein the charging cabinet 220 can charge the handheld battery pack 10a and the backpack battery pack 10b through the first charging interface 2051.

[0106] Furthermore, the control module 201 is electrically connected to and controls the first charging module 2041 to control the charging of the built-in battery module 200 , and the control module 201 is electrically connected to and controls the second charging module 2042 to control the charging of the battery pack connected to the charging interface 205 .

[0107] For example, when the charging device 20 is in the long storage charging mode and the charging device 20 is connected to an external power supply, the control module 201 obtains the remaining power value of the built-in battery module 200 and compares the remaining power value of the built-in battery module 200 with the long storage power value of the battery module. When the remaining power value of the built-in battery module 200 is lower than the long storage power value of the battery module, the control module 201 controls the first charging module 2041 to charge the built-in battery module 200, and after the built-in battery module 200 is charged to the battery module stop power value, the control module 201 controls the first charging module 2041 to stop charging the built-in battery module 200.

[0108] In the long-storage charging mode, when the charging interface 205 is connected to the battery pack, the control module 201 obtains the remaining power value of the battery pack and compares the remaining power value of the battery pack with the long-storage power value of the battery pack. When the remaining power value of the battery pack is lower than the long-storage power value of the battery pack, the battery pack is controlled to charge to the battery pack stop power value and then stop charging. The control module 201 controls the second charging module 2042 to charge the battery pack, and after the battery pack is charged to the battery module stop power value, the control module 201 controls the second charging module 2042 to stop charging the battery pack.

[0109] In one embodiment of the present invention, the battery module long storage capacity value is configured to be 20% to 60% of the battery capacity of the built-in battery module 200 , and / or the battery pack long storage capacity value is configured to be 20% to 60% of the battery capacity of the battery pack 10 .

[0110] Exemplarily, the battery module long storage capacity values ​​are configured as 20%, 30%, 40%, 50%, and 60% of the battery capacity of the internal battery module 200. Preferably, the battery module long storage capacity value is configured as 40% of the battery capacity of the internal battery module 200. The battery pack long storage capacity values ​​are configured as 20%, 30%, 40%, 50%, and 60% of the battery capacity of the battery pack 10. Preferably, the battery pack long storage capacity value G is configured as 40% of the battery capacity of the battery pack 10.

[0111] It is understood that after the control module 201 compares the remaining power value of the internal battery module 200 with the battery module long storage power value, if the remaining power value of the internal battery module 200 is not less than the battery module long storage power value, the control module 201 controls the internal battery module 200 to discharge to the battery module stop power value and then stop discharging, or the internal battery module 200 self-discharges to below the battery module long storage power value. Furthermore, after the control module 201 compares the remaining power value of the battery pack with the battery pack long storage power value, if the remaining power value of the battery pack is not less than the battery pack long storage power value, the control module 201 controls the battery pack to discharge to the battery pack stop power value and then stop discharging, or the battery pack self-discharges to below the battery pack long storage power value.

[0112] In one embodiment, in the long-storage charging mode, the control module 201 obtains the remaining power value of the built-in battery module 200 when the charging device 20 is connected to an external power supply, and compares the remaining power value of the built-in battery module 200 with the battery module long-storage power value. When the remaining power value of the built-in battery module 200 is not lower than the battery module long-storage power value, the control module 201 sends a battery module power prompt information to the user terminal 30 through the wireless communication module 202 to indicate that the power of the built-in battery module 200 exceeds the battery module long-storage power value, so that the user terminal 30 pushes battery module long-storage recommendation information to the user based on the received battery module power prompt information.

[0113] Furthermore, the battery module long-term storage recommendation information is configured to indicate that the remaining power of the internal battery module 200 exceeds the battery module long-term storage power value, and recommends discharging the internal battery module 200 to a value below the battery module long-term storage power value before enabling long-term storage (the long-term storage recommendation information may also be referred to as a prompt discharge recommendation information). Specifically, the battery module long-term storage recommendation information may be in the form of graphic information, text information, voice information, etc., which will not be further described here.

[0114] In one embodiment, in the long-storage charging mode, the control module 201 obtains the remaining power value of the battery pack 10 when the charging interface 205 is connected to the battery pack 10, and compares the remaining power value of the battery pack 10 with the long-storage power value of the battery pack. When the remaining power value of the battery pack 10 is not lower than the long-storage power value of the battery pack, the control module 201 sends a battery pack power prompt information indicating that the battery pack power exceeds the long-storage power value of the battery pack to the user terminal 30 through the communication module 202, so that the user terminal 30 pushes the battery pack long-storage recommendation information to the user based on the received battery pack power prompt information.

[0115] Furthermore, the battery pack long-term storage recommendation information is configured to indicate that the remaining power of the battery pack 10 exceeds the battery pack long-term storage value and recommends discharging the battery pack 10 to below the battery pack long-term storage value before enabling long-term storage. Specifically, the battery pack long-term storage recommendation information can be in the form of graphic information, text information, voice information, etc., which will not be detailed here.

[0116] Of course, the present invention is not limited to this. In another embodiment, when the remaining power value of the built-in battery module 200 is not less than the long-storage power value of the battery module, or when the remaining power value of the battery pack 10 is not less than the long-storage power value of the battery pack, the control module 201 may not send a prompt message to the user terminal 30. Alternatively, in another embodiment, only the control module 201 may send a prompt message to the user terminal 30, and the user terminal 30 may not push a suggestion message to the user. This will not be described in detail here. In one embodiment, the long-storage charging instruction includes a long-storage effective time. The control module 201 controls the charging device 20 to reach the long-storage effective time according to the long-storage effective time and then turns on the long-storage charging mode.

[0117] As shown in Figure 8, after receiving the long-term storage charge instruction, control module 201 determines whether the long-term storage charge instruction carries a long-term storage effective time. If so, it determines whether the current time has reached the long-term storage effective time. If so, it activates the long-term storage charge mode. If not, it returns to the step of determining whether the current time has reached the long-term storage effective time or whether the long-term storage charge instruction carries a long-term storage effective time. Based on this, the long-term storage charge mode can be activated not only immediately after the charging device 20 receives the long-term storage charge instruction, but also at a specific long-term storage effective time, that is, the long-term storage charge mode can be activated on a scheduled basis.

[0118] For example, when the remaining power value of the built-in battery module 200 is not lower than the long storage power value of the battery module, or when the remaining power value of the battery pack 10 is not lower than the long storage power value of the battery pack, the discharge time when the remaining power value is lower than the long storage power value can be estimated based on the discharge efficiency of the built-in battery module 200 or the battery pack 10, and then the long storage effectiveness time can be set according to the discharge time, so that the long storage charging mode is turned on after the remaining power value of the built-in battery module 200 or the battery pack 10 is lower than the long storage power value; the user can also plan the number of charging devices currently needed according to the workload of the garden team, and then turn on the long storage charging mode for the charging devices that will not be used in the remaining period of time; this is not limited here.

[0119] In one embodiment, in the long-storage charging mode, the control module 201 monitors the connection status of the charging device 20 and the external power supply. When the control module 201 detects that the charging device 20 and the external power supply change from a connected state to a disconnected state, or the control module 201 receives a long-storage shutdown instruction sent by the user terminal 30, or the control module 201 detects that the charging device 20 is turned off, the control module 201 controls the charging device 20 to exit the long-storage charging mode.

[0120] As shown in Figure 8, after the long-storage charging mode is turned on, the control module 201 monitors the connection status of the charging device 20 and the external power supply. When the control module 201 detects that the charging device 20 and the external power supply change from a connected state to a disconnected state, that is, the charging device 20 is connected to the external power supply by the user and then disconnected, or the control module 201 receives a long-storage shutdown instruction sent by the user terminal 30, the control module 201 controls the charging device 20 to exit the long-storage charging mode.

[0121] Of course, after the long-storage charging mode is turned on, when the charging device 20 is connected to an external power supply, the control module 201 will also execute the battery module long-storage charging strategy, that is, obtaining the remaining power value of the built-in battery module 200, and comparing the remaining power value of the built-in battery module 200 with the battery module long-storage power value, etc., which will not be repeated here.

[0122] It is understandable that the user terminal is used to perform data interaction with the charging device 20 and provide a human-computer interaction interface to the user. The human-computer interaction includes displaying status information of the charging device 20 to the user and / or receiving control instructions for the charging device 20 input by the user.

[0123] Furthermore, as shown in FIG2 , the user terminal 30 includes an interactive terminal 301 and a cloud server 302 .

[0124] Specifically, the interactive terminal 301 can be configured as a smartphone, a tablet computer, a laptop computer, or other smart wearable device, such as a smartwatch or smart bracelet. Preferably, the interactive terminal 301 is a smartphone equipped with a touch screen capable of human-computer interaction. Specific options for the interactive terminal 301 are not listed here; however, all such options fall within the scope of the present invention, provided they do not exceed the core concept of the present invention.

[0125] The cloud server 302 can select a server with functions such as data storage, information interaction and device control according to actual application requirements, such as a cloud server based on the AWS cloud service platform. The specific selection of cloud servers will not be listed here one by one. Under the premise of not exceeding the core idea of ​​the present invention, it also falls within the scope of protection of the present invention.

[0126] As an example, the charging device 20 is configured with a first wireless communication module 2021. It is understood that the communication module 202 includes the first wireless communication module 2021, or that the communication module 202 is the first wireless communication module 2021. The interactive terminal 301 is configured with a second wireless communication module 3010, and the cloud server 302 is configured to connect to the internet via a network communication module. Preferably, the first wireless communication module 2021 and the second wireless communication module 3010 can be configured as one of a 3G module, a 4G module, a 5G module, a LoRa module, a SigmaFox module, and a NB-IoT module. Preferably, in this embodiment, the first wireless communication module 2021 is a 4G module or a 5G module, and the second wireless communication module 3010 is a 4G module or a 5G module or a WiFi module. The network communication module can be a wired communication method such as fiber optic communication, or other wireless communication methods such as 4G, without limitation. Communication between the charging device 20, the interactive terminal 301, and the cloud server 302 can be achieved via the internet, thereby enabling data exchange between the charging device 20 and the interactive terminal 301. In one embodiment of the present invention, assuming that the charging device 20 is an energy storage charging device and the interactive terminal 301 is a smartphone, a user can send a long-term storage charging instruction to the cloud server 302 via the second wireless communication module 3010 of the interactive terminal 301. After receiving the long-term storage charging instruction, the cloud server 302 sends the long-term storage charging instruction to the charging device 20. The control module 201 of the charging device 20 receives the long-term storage charging instruction sent by the cloud server 302 via the first wireless communication module 2021, so that the control module 201 can perform long-term storage charging management on the charging device 20 according to the long-term storage charging instruction.

[0127] In other embodiments, the charging device 20 can also be an energy storage type garden robot tool, such as an intelligent lawn mower. The energy storage type garden robot tool includes a working part, and its built-in battery module 200 is used to power the working part. Of course, the charging device of the present invention is not limited to this and is not listed here one by one.

[0128] Of course, the present invention is not limited to this. In another embodiment, the charging device 20 can also be a battery pack 10. In this case, the battery cells of the battery pack 10 (hereinafter referred to as battery pack cells) correspond to the built-in battery module 200. The battery pack 10 includes a control module 201, a wireless communication module 202 and a power input terminal 203. The power input terminal 203 is the charging interface of the battery pack 10, which is used to connect an external charging device for charging. The external charging device is an external power source. Preferably, the external charging device can be the aforementioned energy storage charging device. The control module 201 is electrically connected to the wireless communication module 202 and can communicate with the user terminal 30 through the wireless communication module 202. The control module 201 receives a long-storage charging instruction from the charging device sent by the user terminal 30 via the wireless communication module 202, and controls the battery pack 10 to enter a long-storage charging mode based on the long-storage charging instruction. In the long-storage charging mode, the control module 201 obtains the remaining power value of the battery pack cells while the battery pack 10 is connected to an external charging device, and compares the remaining power value of the battery pack cells with the long-storage power value of the battery module. When the remaining power value of the battery pack cells falls below the long-storage power value of the battery module, the control module 201 controls the battery pack cells to charge to the battery module stop power value and then stops charging. The battery module stop power value is set to be offset by the battery module offset ΔR relative to the battery module long-storage power value, where -50%*battery module long-storage power value ≤ battery module offset ΔR ≤ 50%*battery module long-storage power value. In other words, the battery pack controls its own long-storage charging process.

[0129] The battery pack 10 communicates with the interactive terminal 301 via wireless communication. As an example, the battery pack 10 includes a third wireless communication module, through which the battery pack 10 can communicate with the interactive terminal 301 and receive long-term storage charging instructions sent by the interactive terminal 301. The third wireless communication module can be configured as one of a 3G module, a 4G module, a 5G module, a Lora module, a Sigfox module, and an NB-IOT module. Preferably, in this embodiment, the third wireless communication module is configured as a 4G module or a 5G module.

[0130] In the above embodiment, the control strategy for controlling the charging of the built-in battery module 200 or the battery pack 10 in the long storage charging mode is configured in the charging device, that is, the software program for implementing the above control strategy is configured in the charging device, preferably, configured in the control module 201.

[0131] In other embodiments, the control strategy for controlling the charging of the internal battery module 200 or battery pack 10 in the long-storage charging mode may also be configured on the cloud server 302, that is, the software program for implementing the above-mentioned control strategy is configured on the cloud server 302. The cloud server 302 communicates with the charging device 20 to obtain the remaining power value of the internal battery module 200 or battery pack 10 in real time, and compares the remaining power value with the long-storage power value. When the remaining power value of the internal battery module 200 or battery pack 10 is lower than the long-storage power value, the cloud server 302 sends a control instruction to charge the internal battery module 200 or battery pack 10, and controls the internal battery module 200 or battery pack 10 to charge to the corresponding stop power value of the internal battery module 200 or battery pack 10. The details will not be repeated here.

[0132] The present application also provides an energy device. Referring to Figure 10, the energy device (which can be configured as a charging device) includes a shell, a wireless communication module, and a battery module and a control module arranged in the shell. The control module includes a signal input end and a communication interface. The control module receives the usage signal of the energy device through the signal input end, and obtains the usage record data of the energy device based on the usage signal of the energy device. The control module is electrically connected to the wireless communication module through the communication interface. The control module can communicate with the user terminal through the communication interface and the wireless communication module to transmit the usage record data of the energy device to the user terminal.

[0133] The energy device or the user terminal monitors whether the unused time of the energy device exceeds the set time threshold based on the usage record data of the energy device. When the unused time of the energy device exceeds the set time threshold, the control module and / or the user terminal executes the set action so that the user can manage the power of the battery module.

[0134] It is understandable that the usage record data of the energy device includes events and the time when the events occurred, and the time difference between the current time and the time when the last recorded event occurred is the unused time of the energy device.

[0135] It should be noted that the set time threshold in the present invention can be a time set by the user according to the specification parameters of the charging device 20, etc. The time can be one week, half a month, one month or even half a year, etc., which will not be repeated here.

[0136] Furthermore, the energy device can be configured as the charging device 20 described in the aforementioned embodiment, which can be either the energy storage charging device described in the aforementioned embodiment, or the energy storage garden robot tool described in the aforementioned embodiment, or the battery pack described in the aforementioned embodiment. The specific structure of the charging device 20 will not be described in detail here. For the example of the energy device being an energy storage charging device, the energy device battery module is the built-in battery module described in the aforementioned charging device embodiment. The specific implementation of the energy device can be referred to in the aforementioned charging device embodiment and will not be described in detail here.

[0137] In one embodiment, the user terminal 30 monitors whether the unused time of the energy device exceeds the set time threshold. When the unused time of the energy device exceeds the set time threshold, the user terminal 30 executes the set action; the user terminal 30 executes the set action configuration as: the user terminal 30 pushes long storage reminder information to the user to prompt the user to manage the power of the battery module.

[0138] In another embodiment, the energy device monitors whether the unused time of the energy device exceeds a set time threshold. When the unused time of the energy device exceeds the set time threshold, the energy device and the user terminal 30 execute a set action; wherein, the energy device executes the set action configured as follows: the control module sends an indication message to the user terminal 30 through the wireless communication module, and the indication message is used to indicate that the energy device has not been used for a set time; the user terminal 30 executes the set action configured as follows: after receiving the indication message, the user terminal 30 pushes a long-storage prompt message to the user to prompt the user to manage the power of the battery module.

[0139] Furthermore, the long-term storage prompt information can be configured to provide a text prompt to the user; can also be configured to provide the user with a long-term storage mode quick selection entry; or can also be configured to provide the user with a text prompt and a long-term storage mode quick selection entry. In response to the user triggering the long-term storage mode quick selection entry, the user terminal can send a long-term storage charging instruction to the energy device. The control module of the energy device receives the long-term storage charging instruction sent by the user terminal via the wireless communication module and controls the energy device to activate the long-term storage charging mode according to the long-term storage charging instruction.

[0140] For example, a text prompt message could read: "×× device has not been used for ×× time, it is recommended to enable long-term storage charging mode." By providing users with a quick entry to long-term storage mode, users can quickly enable long-term storage charging mode for the corresponding energy device upon receiving the long-term storage prompt message. Once they confirm that the energy device does not need to be enabled in long-term storage charging mode, they can also quickly disable the prompt, making operation convenient.

[0141] In another embodiment, the energy device monitors whether the unused time of the energy device exceeds a set time threshold. When the unused time of the energy device exceeds the set time threshold, the energy device executes a set action; the energy device executes the set action configured as: the control module controls the energy device to turn on the long storage charging mode.

[0142] In the above embodiment, the aforementioned long storage charging mode can be configured as follows: in the long storage charging mode, the control module obtains the remaining power value of the battery module when the energy device is connected to an external power supply, and compares the remaining power value of the battery module with the long storage power value. When the remaining power value of the battery module is lower than the long storage power value, the battery module is controlled to charge to the stop power value and then stop charging; the stop power value is set to an offset ΔR relative to the long storage power value, where -50%*long storage power value ≤ offset value ΔR ≤ 50%*long storage power value.

[0143] In the above embodiment, the aforementioned long storage charging mode can also be configured as follows: in the long storage charging mode, the control module obtains the used power value of the battery module when the energy device is connected to an external power supply, and compares the used power value of the battery module with the used set power value. When the used power value of the battery module is higher than the used set power value, the battery module is controlled to charge to the stop power value and then stop charging; the stop power value is set to an offset ΔR relative to the long storage power value, where -50%*long storage power value ≤ offset value ΔR ≤ 50%*long storage power value.

[0144] It should be noted that the total capacity of the battery module is the sum of the remaining capacity value and the used set capacity value. For example, if the remaining capacity value and the used set capacity value are provided as percentages, then the remaining capacity value plus the used set capacity value equals 100%. Methods for implementing long-term storage charging control using equivalent parameters calculated based on this transformation relationship are all within the scope of protection of this application.

[0145] Based on this, the user terminal 30 can monitor the unused time of the energy device, and when the unused time of the energy device exceeds the set time threshold, the user terminal 30 pushes a long-term storage prompt message, allowing the user to choose whether to enable the long-term storage charging mode for the charging device 20. This not only meets the user's long-term storage charging management needs of monitoring the charging device 20, but also ensures the accuracy of the judgment of long-term storage needs. It not only avoids the problem of energy devices being unused and not long-term stored for a long time, resulting in irreversible damage caused by self-discharge of the energy device, but also avoids the problem of energy devices that need to be used automatically enabling long-term storage, resulting in low power of the energy device affecting subsequent use. At the same time, compared with the energy device monitoring its own unused time, monitoring the unused time of the energy device through the user terminal 30 can monitor the unused time of the charging device 20 even when the charging device 20 is turned off based on the device usage records stored in the cloud server, and then discover the long-term storage needs of the turned-off charging device, which can better meet the user's needs for long-term storage charging management.

[0146] In one embodiment of the present invention, in the long storage charging mode, the control module 201 obtains the remaining power value of the built-in battery module 200 when the charging device 20 is connected to an external power supply, and compares the remaining power value of the built-in battery module 200 with the battery module long storage value. When the remaining power value of the built-in battery module 200 is lower than the battery module long storage value, the built-in battery module 200 is controlled to charge to the battery module stop power value and then stop charging. The battery module stop power value is set to the battery module offset ΔR relative to the battery module long storage value, where -50%*battery module long storage value ≤ battery module offset ΔR ≤ 50%*battery module long storage value.

[0147] Of course, the present invention is not limited to this. In another embodiment, when the charging device 20 is in the long-storage charging mode, the control module 201 obtains the remaining power value of the battery pack 10 when the charging interface 205 is connected to the battery pack 10, and compares the remaining power value of the battery pack 10 with the long-storage power value of the battery pack. When the remaining power value of the battery pack 10 is not lower than the long-storage power value of the battery pack, the control module 201 sends a battery pack power prompt information indicating that the battery pack power exceeds the long-storage power value of the battery pack to the user terminal 30 through the communication module 202, so that the user terminal 30 can push the battery pack long-storage recommendation information to the user based on the received battery pack power prompt information.

[0148] It should be noted that for the specific implementation and application scenarios of the long-storage charging mode of the energy device, reference can be made to the aforementioned charging device embodiments, which will not be described in detail here.

[0149] The present application also provides a method for managing power in an energy device. As shown in FIG10 , the energy device includes a housing, a wireless communication module, and a battery module and a control module disposed within the housing. The control module is electrically connected to the wireless communication module and can communicate with a user terminal via the wireless communication module. The power management method includes the following steps:

[0150] S1. The control module receives a usage signal of the energy device and obtains usage record data of the energy device based on the usage signal of the energy device;

[0151] S2. The user terminal obtains usage record data of the energy device by communicating with the control module;

[0152] S3. The user terminal monitors whether the unused time of the energy device exceeds the set time threshold based on the usage record data of the energy device. When the unused time of the energy device exceeds the set time threshold, the user terminal executes the set action so that the user can manage the power of the battery module.

[0153] Furthermore, the user terminal executes the setting action configuration as follows: the user terminal pushes a long-storage prompt message to the user to prompt the user to manage the power of the battery module.

[0154] In one embodiment, the power management method further includes:

[0155] Sending a long-storage charging instruction to the control module via the user terminal;

[0156] After receiving the long storage charging instruction, the control module controls the energy device to start the long storage charging mode according to the long storage charging instruction.

[0157] In the long storage charging mode, the control module obtains the remaining power value of the battery module when the energy device is connected to the external power supply, and compares the remaining power value of the battery module with the long storage power value. When the remaining power value of the battery module is lower than the long storage power value, the battery module is controlled to charge to the stop power value and then stop charging; the stop power value is set to an offset ΔR relative to the long storage power value, where -50%*long storage power value ≤ offset ΔR ≤ 50%*long storage power value.

[0158] In another embodiment, in the long storage charging mode, the control module obtains the used power value of the battery module when the energy device is connected to an external power supply, and compares the used power value of the battery module with the used set power value. When the used power value of the battery module is higher than the used set power value, the battery module is controlled to charge to the stop power value and then stop charging; the stop power value is set to an offset ΔR relative to the long storage power value, where -50%*long storage power value ≤ offset ΔR ≤ 50%*long storage power value.

[0159] It should be noted that for the specific implementation and application scenarios of the long-storage charging mode of the energy device, reference can be made to the aforementioned charging device embodiments, which will not be described in detail here.

[0160] It should be noted that the control module described in the above embodiments has functions such as data transmission and reception, data processing, etc., and can be configured as a single-chip microcomputer, MCU, etc., but is not limited to this, and will not be described in detail here.
