As people's pace of life accelerates, various types of power tools (such as automated home equipment, DIY tools, etc.) are becoming more and more popular around the world, and commercial garden tools are one of them.

Commercial garden tools are professional power tools designed for garden workers or garden companies. They are generally called garden landscape maintenance equipment. They usually work on lawns, hedges, flowers, trees or gardens, etc., and can include the following tools. One or more of: lawn mowers, lawn mowers, pruners, chain saws, blowers, leaf shredders, snow blowers, etc.

The working power of commercial garden tools is generally high. For example, the power of a garden hair dryer is usually 2300W, and the power of a lawn mower is usually 2600W. Therefore, using fuel as a power source can well meet the working needs of commercial garden tools. And it can support commercial garden tools for long-term work. However, the use of fuel tools will cause environmental pollution, and the noise of fuel tools is loud, which is not good for the health of users. Therefore, people are always looking for alternatives to fuel powered tools.

Electricity is an environmentally friendly, clean, and renewable energy source. Electric tools using it as a power source are becoming more and more popular. Favored by people. Under normal circumstances, power tools can be powered by either DC power or AC power. However, the work of commercial garden tools is usually carried out outdoors, and AC power is difficult to obtain. Therefore, in the field of commercial garden tools, it is more appropriate to use DC power supply. Preferably, the DC power supply can be a battery pack, which is convenient for the work team to carry with them when they go out.

The working scenario of commercial garden tools can be roughly described as follows: When the work team goes out to work during the day, they use vehicles to carry various garden tools needed for work to various gardens, such as push lawn mowers, smart lawn mowers and other wheeled lawn mowers. Power tools, as well as handheld power tools such as lawn mowers, pruners, and hair dryers; at the same time, the work team also needs to carry DC power sources, such as battery packs.

When working, the work team first came to the first garden and worked with various garden power tools they carried. When it comes to gardening, mowing usually takes the longest, and while the size of lawns varies from household to household, the average lawn mowing time is between 20 and 40 minutes. Therefore, at every garden, a worker immediately starts cutting the grass with a lawnmower. During the mowing period, another worker will use hand-held power tools to complete other types of work in sequence. For example, another worker will cut the grass first, then prune the branches, and then blow the grass. The two workers will complete all the work almost at the same time, and then work The team then moved to the second garden. This cycle continues until the day's work is completed.

It can be seen that commercial garden tools have a heavy workload and long working hours; if you want to use electric tools to replace fuel tools, you must consider the continuous energy supply of electric tools.

One solution is to prepare a large number of battery packs to power power tools, which undoubtedly brings inconvenience and high work cost to the outgoing team who already carry many different types of garden tools; another solution is to use The outdoor energy storage power supply charges the battery pack directly on site.

Existing outdoor energy storage power supplies generally serve home users. For example, they can serve as backup power sources during camping. Therefore, the capacity of the battery units they store generally does not exceed 5kw˙h, and the output power generally does not exceed 100W. They cannot meet the needs of garden users. The power requirements of the tool; at the same time, the output interface of the energy storage power supply is mostly configured as a USB interface or an AC socket, which is not suitable for the plug terminal of the battery pack for electric tools; more troublesome, the existing energy storage The battery unit and electronic control unit of the power supply are usually placed inside the same casing. The capacity of the energy storage power supply is limited by the capacity of the only battery unit; once the battery unit is low in power, charging of the battery unit must be considered first. The energy storage power supply can be used to charge the external charging components; and the energy storage power supply case is also provided with inlets and outlets for external airflow to enter the case for heat dissipation. The outdoor environment is complex and changeable, and impurities such as rainwater and dust will enter the interior of the casing through the aforementioned air inlet and outlet, contaminating the battery unit and electronic control unit, making them unable to work.

Based on this, this application provides an energy storage power supply, which separates the battery cabinet and the charging cabinet. The charging cabinet can be selectively connected to at least one battery cabinet, thereby expanding the capacity of the energy storage power supply; furthermore, the battery cabinet Set up separately from the charging cabinet, the design of each cabinet can fully comply with its own characteristics. For example, the battery cabinet requires a higher protection level, the charging cabinet requires a higher protection level and higher heat dissipation requirements, etc., which can withstand It can withstand the test of various outdoor environments; in addition, the battery unit has large capacity and high output power, and can continuously power the battery pack of garden tools for a long time. When the work team goes out to work, they can place the energy storage power supply, battery pack, and various garden tools in the vehicle, and follow the work team from one garden to another. Since the energy storage power supply has enough electricity stored in advance to charge the battery pack, the work team can continuously supply power to garden tools by carrying the energy storage power supply and a small number of recyclable battery packs when going out to work, eliminating the need for Carrying a large number of battery packs makes it easy for the work team to carry when going out and reduces the cost of use.

As shown in Figures 1 to 4, it is an energy storage power supply 100 provided by this application. The energy storage power supply 100 includes a battery cabinet 10 and a charging cabinet 20 . Among them, the battery cabinet 10 is used to store DC power, and the charging cabinet 20 is used to connect with the battery cabinet 10 to convert the DC power received from the battery cabinet 10 and provide it to the outside through the output interface provided on it. The charging unit is charged.

Here, the direction in which the front part of the charging cabinet 20 or the battery cabinet 10 extends is the length direction X; the direction in which the right part perpendicular to the front part extends is the width direction Y, and the height direction is Z.

Next, the battery cabinet 10 and the charging cabinet 20 will be described respectively.

As shown in Figures 5 and 6, it is a battery cabinet 10 provided by this application. The battery cabinet 10 has a roughly rectangular parallelepiped structure and mainly includes a battery case 12 and a battery pack 14 housed inside for storing DC power.

As shown in FIG. 7 , the battery core group 14 mainly includes battery cores 141 and support members 142 that are electrically connected to each other. The support member 142 is used to support the battery core 141 .

We know that the weight and volume of the battery are directly related to its capacity. When the capacity of the battery pack is increased to support high-power commercial garden tools for long periods of time, the weight and volume of the battery pack will also increase accordingly. In this implementation, the battery core is a lithium iron phosphate battery, with a capacity of about 5kw˙h, a weight of not less than 30KG, and dimensions of length, width and height of about 600mm x215mm x140mm.

Once the battery pack 14, especially the battery cell 141, comes into contact with impurities such as rain and dust, it is easily damaged and cannot work properly; therefore, the battery pack 14 requires a higher level of protection.

The balance valve 13 includes a breathable film, which is used to connect the inside and outside of the first battery case 11 to balance the air pressures inside and outside the first battery case 11 .

Furthermore, when the air pressure difference between the inside and outside of the first battery case 11 reaches a preset value, for example, a large amount of gas caused by abnormal combustion of the battery pack 14 accumulates in a short period of time, the breathable film will rupture. , that is, the balance valve 13 is opened to quickly discharge the gas in the first battery case 11 to avoid a dangerous situation caused by excessive internal air pressure in the closed first battery case 11 .

In one embodiment, the first battery case 11 is made of metal material to better protect the battery pack 14 located therein.

Most of the work of the energy storage power supply 100 is carried out outdoors. Direct sunlight on the battery cabinet 10 can easily cause the internal battery pack 14 to overheat, causing the battery cabinet 10 to fail to work normally. In serious cases, it may even cause dangerous situations such as spontaneous combustion and explosion of the battery pack 14. To this end, in this embodiment, as shown in FIGS. 9 to 10 , the battery case 12 further includes a second battery case 15 located outside the first battery case 11 , and the second battery case 15 is generally in a rectangular parallelepiped structure.

In this embodiment, the battery case 12 is constructed as a double-shell structure, and there is a gap between the first battery case 11 and the second battery case 15 to form a heat insulation layer, thereby effectively reducing the impact of outdoor ambient temperature on the battery. The influence of the core pack can, for example, effectively reduce the heat transmitted from the sun to the first battery casing, thereby avoiding the occurrence of the above-mentioned dangerous situations such as spontaneous combustion and explosion.

Further, the insulation layer is filled with air, a poor conductor of heat.

Of course, in other embodiments, the heat insulation layer can also be filled with other types of gases, such as nitrogen.

As shown in FIG. 9 , along the length direction The heat generated by the battery pack 14 during operation is dissipated.

In this embodiment, the battery pack 14 is fixed in the first battery case 11 through threaded locking parts, and the first battery case 11 is fixed in the second battery case 15 through threaded locking parts.

Of course, the connection method between the battery pack 14 and the first battery case 11 is not limited to screw connection. For example, it can be riveting, welding, etc., which can be determined according to the actual situation, and is not specifically limited here in this application.

The connection method between the first battery case 11 and the second battery case 15 is not limited to screw connection, for example, it can be riveting, welding, etc., which can be determined according to the actual situation, and is not specifically limited here in this application.

Normally, the power stored in the energy storage power supply 100 can satisfy the work team working outside for a day. Therefore, when resting at night, the energy storage power supply 100 can be brought back to the residence, and the battery cabinet 10 and multiple external charging components connected to the charging cabinet 20 can be charged using commercial power.

When the energy storage power supply 100 is charged through the mains at night, the mains gives priority to charging the battery cabinet 10 in the energy storage power supply 100. After the battery cabinet 10 is full, the mains then charges the external charging components installed on the charging cabinet 20. .

The fourth input interface 32 is configured as a DC input interface for connecting an external DC power source, such as a vehicle-mounted solar power source, so that the charging cabinet 20 can charge the battery cabinet 10 and external charging components through solar energy when working outside.

In this embodiment, when the energy storage power supply 100 is connected to an external charging component, the solar power source gives priority to charging the external charging component, and then charges the battery cabinet 10 after the external charging component is fully charged.

The first type of battery pack 201 is mainly used to power power tools with large volume and/or high power, such as push lawn mower 300, hair dryer 400, etc. The second type of battery pack 203 is used to power handheld electric tools, such as the lawn trimmer 500 and the pruning machine 600.

As shown in Figure 20, the first type battery pack mounting base 34 includes: a base 341, a mounting part 342, an output interface 343, and a locking device. The above structures will be explained respectively below.

The base portion 341 is used to connect with the front portion 221 to install the first type battery pack mounting base 34 to the charging case 22 . Specifically, the base 341 is provided with a number of threaded holes, and the inner wall of the front part 223 is provided with corresponding screws that match the threaded holes.

When installing the first type battery pack mounting seat 34, first pass the screw rod of the front part 223 through the threaded hole of the first type battery pack mounting seat 34, and make the mounting part 342, output interface 343, etc. protrude from the opening of the front part 223; finally The front part 223 and the base part 341 are then fixed with nuts.

The mounting part 342 is disposed protruding from the base 341 and includes a first type of rail 342a and a second type of rail 342b. The first type of rail 342a is used to cooperate with the installation slide rail of the first type of battery pack 201 to detachably and slidably connect the charging cabinet 20 with the first type of battery pack 201; the second type of rail 342b is used to cooperate with the first type of battery pack 201. The installation slide rails of the second type battery pack 203 cooperate to detachably and slidably connect the charging cabinet 20 with the second type battery pack 203 . The first type rail 342a and the second type rail 342b respectively have a double-rail structure, and a first type rail 342a and a second type rail 342b share a supporting part.

The output interface 343 matches the charging and discharging interface of the first type battery pack 201 or the second type battery pack 203 . In this embodiment, the charging and discharging interfaces of the first type battery pack 201 and the second type battery pack 203 use plum blossom contacts, and correspondingly, the output interface 343 uses inserts corresponding to the plum blossom contacts.

Specifically, as shown in FIG. 21 , the output interface 343 includes a positive plug 3431 , a negative plug 3432 , an analog signal communication plug 3433 , a first digital signal communication plug 3434 and a second digital signal communication plug 3435 . The second digital signal communication plug 3435 includes two plugs 3435a and 3435b, and the two plugs are insulated from each other.

When a vehicle is moving, it is inevitable that it will encounter braking, bumps, etc. In order to prevent the external battery pack from sliding out of the battery pack mounting seat and causing damage to the external battery pack due to vibration of the vehicle, the battery pack mounting seat in this embodiment also includes a locking device. The locking device is used to lock the connection state of the external battery pack and the battery pack mounting base. For details, please see Figure 20, Figure 22a and Figure 22b.

The locking device includes a lock catch 3441 and an unlocking button 3442, both of which are movably supported on the base 341 by a first spring 38 and a second spring 40 respectively.

Here, when the lock 3441 is not subjected to external force, the position it is in is defined as the natural position; when the lock 3441 is subjected to external force, the position where it moves backward against the force of the first spring 38 is defined as the retracted position.

Next, the working principles of the lock 3441 and the unlocking button 3442 will be described by taking the process of installing an external battery pack to the battery pack mounting base and removing the battery pack from the battery pack mounting base as an example.

Referring to Figure 20, when it is necessary to charge the external battery pack, install the battery pack from top to bottom along the first type rail 342a to the battery pack mounting base; at this time, the lock 3441 moves toward the battery pack under the abutting action of the battery pack. and then moves to the retracted position shown in Figure 22b; after the battery pack is installed in place, the lock 3441 returns to its natural position as shown in Figure 22a under the action of the first spring 38, and is locked with the locking portion of the battery pack. connection, thereby installing the external battery pack on the battery pack mounting base 34.

When the battery pack needs to be removed, the worker needs to overcome the elastic force of the second spring 40 and press the unlock button 3442; the lower end of the unlock button 3442 contacts the lock 3441, driving it to move backward, so that the lock 3441 and the battery pack lock The stop part is detached; at this point, the lock of the external battery pack is released, and it can slide out of the first type track 342a.

In the energy storage power supply 100 of this embodiment, the charging current of the charging cabinet 20 for the external battery pack is relatively large. If the battery pack accidentally slides out of the battery pack mounting base during charging, or if the charging is not completed and the user needs to use an external battery pack to slide the battery pack out of the battery pack mounting base, In this case, the electrode sheet will spark due to the charging current, and then be ablated and unable to work properly. For this reason, in the unlocking device of this embodiment, when the user presses the unlock button 3442, an electronic switch will be triggered. The electronic switch is used to disconnect the charging circuit of the charging cabinet 20 from the external battery pack connected to the battery pack mounting base. When the user releases the unlock button or reaches a predetermined time, the electronic switch returns to connecting the charging circuit of the battery pack mounting base to the external battery pack installed thereon.

In this embodiment, the first type battery pack mounting base 34 is also configured to detachably connect to the second type battery pack 203 . To this end, the mounting part 342 is designed to include two types of rails, the first type of rail 342a is used to detachably connect the first type of battery pack 201, and the second type of rail 342b is used to detachably connect the second type of battery pack 203, Therefore, the first type battery pack mounting base 34 can charge both the first type battery pack 201 and the second type battery pack 203 while sharing the output interface 343 and the locking device, thus simplifying the structure. , improving the adaptability of the first type battery pack mounting base 34.

The structure of the second type battery pack mounting base 36 is similar to the structure of the first type battery pack mounting base 34, both including a second type rail, an output interface and a locking device, and the second type rail, output interface and locking device are The structure, relative position, size and mode of operation are the same as those of the first-type battery pack mounting base 34. The only difference is that the second-type battery pack mounting base 36 is only provided with a second-type track and can only install second-type battery packs.

In this embodiment, the extending direction of the first type of rail 342a and the second type of rail 342b is parallel to the vertical direction, that is, the sliding direction of the external battery pack is parallel to the vertical direction. With this arrangement, on the one hand, the external battery pack's own gravity can be used to easily slide it into the battery pack mounting base without the user exerting more force; on the other hand, setting the track in the vertical direction can further save energy storage. The use space of the power supply 100 itself improves the utilization rate of the carriage. This is because during the process of inserting and unplugging the battery pack, a certain space must be reserved in the sliding direction of the battery pack, which can also be said to be the usage space of the energy storage power supply 100 . The track is arranged in the vertical direction and only occupies the space above the energy storage power supply 100, while the space above the energy storage power supply 100 is ample. If the first type of rail 342a or the second type of rail 342b is designed to extend in the horizontal or inclined direction, a certain horizontal space must be made available for the sliding of the external battery pack, which will inevitably occupy the original space on the carriage. Space that can be used to place lawn mowers and trimmers.

In this embodiment, as shown in FIG. 4 , the battery pack mounting base further includes a second air inlet 6 connected to the first chamber 1 . The second air inlet 6 is designed such that when an external battery pack is connected to the battery pack mounting base, the second air inlet 6 will be connected with the air flow outlet of the external battery pack. With this arrangement, when the fan located inside the charging cabinet 20 is working, external air will enter the interior of the battery pack from the air inlet of the battery pack. After dissipating heat for the battery pack, it will enter the first air outlet from the second air inlet 6 through the air outlet of the battery pack. The air flows out from the inside of the chamber 1 and finally to the air outlet of the charging cabinet 20 .

Therefore, in the charging cabinet 20 of this embodiment, the air inlet 6 connected to the first chamber 1 is provided on the battery pack mounting base, and the air inlet 6 is connected with the air flow outlet of the external battery pack, so that the fan can not only accommodate The first electrical component inside the first chamber 1 dissipates heat and can also dissipate heat for the external battery pack connected thereto, thereby improving the heat dissipation efficiency of the external battery pack.

In this embodiment, the charging cabinet 20 is provided with a total of three battery pack mounting seats, including two first-type battery pack mounting seats 34 provided on the front part 221 and one on the right part 224 of the charging case 22 . A Category 2 battery pack mount 36. Two of the first type battery pack mounting seats 34 are configured to charge the first type battery pack 201 or the second type battery pack 203; one second type battery pack 36 mounting seat is configured to charge the second type battery pack 203; With this arrangement, the charging cabinet 20 can simultaneously charge multiple battery packs with different capacities at night, which improves the charging efficiency and makes it easier for the work team to carry battery packs with sufficient power for work during the day.

Furthermore, because the front portion 221 of the charging case 22 is parallel to the extension plane of the power converter, that is, among the respective side portions of the charging case 22, the size of the front portion 221 is larger; therefore, the two first-type batteries are The pack mounting seat 34 is arranged on the front part 221 of the housing 22, and a second type battery pack mounting seat 36 is arranged on the right part 224 of the housing 22, which is more consistent with the structural dimensions of the charging housing 22 itself. In this way, battery pack mounting seats that meet the long-term work needs of the gardening team can be arranged on both sides of the charging case 22, and the structure of the energy storage power supply 100 is more compact.

Furthermore, the electric energy provided by the charging cabinet 20 to the external battery pack can also be understood as the electric energy received by the charging cabinet 20 through the input interface, which is converted into electric energy in a specific current and voltage form through the power converter, and the battery pack mounting base Being disposed close to the first chamber 1 , that is, the battery pack mounting seat is disposed close to the power converter, which simplifies the circuit wiring between the electronic control unit of the charging cabinet 20 and the battery pack mounting seat.

In this embodiment, the input interface module 28 and the second type battery pack mounting base 36 are both disposed on the right part 224 of the charging case 22; such an arrangement conforms to the operating habits of the user's right hand on the one hand, and on the other hand, the charging interface module 28 is arranged on the same side as the second type battery pack mounting base 36 and can share part of the operating space, saving the space occupied by the energy storage power supply 100 when in use.

Furthermore, the air outlet 4 is provided on the left part 223 of the charging case 22 instead of the right part 224, which can effectively prevent the hot air flowing out from the first chamber 1 from affecting the battery pack installed on the second type battery pack mounting seat 36. Adverse effects of the second type of battery pack 203.

In order to facilitate the user to intuitively understand the charging status of the external battery pack connected to each battery pack mounting base and whether a fault occurs, an indicator light 42 is provided near each battery pack mounting base. The indicator light 42 indicates different charging states through color and flashing frequency. Indicating the charging status through the color and flashing frequency of the indicator light is a conventional technology in the charger field, and will not be explained in detail here.

In order to match the high power requirements of commercial garden tools, a DC power supply is required to provide electric energy, that is, the capacity and weight of the battery pack are relatively large. As mentioned above, the weight of the first type battery pack 201 can reach 7.9KG, and the weight of the second type battery pack 203 can reach 2.8KG. In order to avoid installing the first type battery pack 201 or the second type battery pack 203 After arriving at the charging cabinet 20, the charging cabinet 20 is caused to tip over, especially along the width direction of the charging cabinet 20. The charging cabinet 20 in this embodiment is configured as follows:

In this embodiment, the front part 221, the rear part 222 and the partition 220 are parallel in pairs; and the distance between the partition 220 and the rear part 222 is smaller than the distance between the partition 220 and the front part 221. Therefore, when the charging case 22 is made of the same metal material, the center of gravity of the charging case 22 itself is located closer to the rear portion 222 .

Furthermore, most of the electronic control units are arranged on the partition 220 and supported by the partition 220 . Therefore, when the charging cabinet 20 is not connected to an external battery pack, the center of gravity of the charging cabinet 20 itself is positioned closer to the rear portion 222 , that is, the center of gravity of the charging cabinet 20 itself is positioned further away from the first type battery pack mounting base 34 .

In this embodiment, when the charging cabinet 20 is not connected to an external battery pack, the weight of the charging cabinet 20 is at least 50KG. The plane where the front part 221 is located is defined as the first plane M, and the plane where the rear part 222 is located is defined as the second plane N.

When the first type of battery pack mounting base 34 is connected to an external battery pack, the center of gravity of the whole formed by the charging cabinet 20 and the external battery pack will move toward the front 221 along the width direction Y; however, due to the weight of the charging cabinet 20, And its own center of gravity is arranged closer to the rear portion 222; therefore, even if an external battery pack is connected, the overall center of gravity formed by the charging cabinet 20 and the external battery pack will still fall on the first plane M and the second plane N. In the space, the charging cabinet 20 and the external battery pack will not fall over.

Because the weight of the first type battery pack 201 is greater than the weight of the second type battery pack 203, the probability of the charging cabinet 20 tipping over when it is installed in the charging cabinet 20 is correspondingly greater than when the second type battery pack 203 is installed in the charging cabinet 20. The resulting probability of the charging cabinet 20 tipping over. Therefore, different numbers of first-type battery packs 201 will be installed in the charging cabinet 20 next. For example, the influence of the external battery pack on the center of gravity of the charging cabinet 20 is roughly illustrated.

As shown in FIG. 23 , when the charging cabinet 20 is not connected to an external battery pack, the center of gravity of the charging cabinet 20 falls at point A along the width direction Y of the charging cabinet 20 . When one and only one of the two first-type battery pack mounting seats 34 is connected to the first-type battery pack 201 , in the width direction Y, the charging cabinet 20 and the first-type battery pack 201 form a whole. The center of gravity falls at point B; when the two first-type battery pack mounting bases 34 are both connected to the first-type battery pack 201, in the width direction Y along the charging cabinet 20, the charging cabinet 20 and the first-type battery pack 201 are connected to each other. The center of gravity of the entire battery pack 201 is located at point C. Point A, point B, and point C all fall in the space defined by the first plane M and the second plane N.

It should be noted that in this embodiment, along the width direction Y of the charging cabinet 20 , the second type battery pack mounting base 36 is centrally located on the right part of the housing 22 . Therefore, whether the second type battery pack mounting base 36 is connected to an external battery pack or not, or in other words, the weight of the external battery pack installed to the second type battery pack mounting base 36 will not cause the charging cabinet 20 to move in the width direction. of dumping. Therefore, only the influence of the first type battery pack mounting seat 34 provided on the front portion 221 on the overall center of gravity of the charging cabinet 20 when connecting an external battery pack will be discussed here.

As shown in FIG. 2 , the top 225 of the charging cabinet 20 is also provided with a carrying handle 21 . The number of handles is two, and they are respectively pivotally provided on the charging case 22 along the horizontal direction X. When the charging cabinet 20 is in a carrying state, the handle 21 is pivoted to a state perpendicular to the top 225 of the charging case 22 for easy grasping; when the charging cabinet 20 is in a normal use state, the handle 21 is pivoted to a position on the top 225 of the charging cabinet 22 . It is advisable that the groove does not exceed the top surface of the charging case 22 .

Further, the top 225 of the charging cabinet 20 is also provided with a display screen 44 for displaying charging information of the external battery pack and the battery cabinet 10 . Specifically, the display screen 44 displays the charging status of each battery pack currently connected to the battery pack mounting base in digital form, for example, the current charging information can be displayed in the form of a percentage. As shown in Figure 2, the display screen 44 is also provided with operating components. The operating components include first operating keys 441 and second operating keys 442 . Among them, the first operation key 441 is a power-on key. When the power-on key 441 is pressed, the energy storage power supply 100 enters a waiting state from a rest state; the second operation key 442 is a fast charging mode selection key. When the operation key 442 is pressed, the energy storage power supply 100 enters the fast charging mode.

When the energy storage power supply 100 is working normally, it is placed on the carriage. The things placed in the carriage may also include garden tools such as smart lawn mowers and push lawn mowers. In order to prevent garden tools from colliding with the first-type battery pack 201 or the second-type battery pack 203 installed in the charging cabinet 20 , the charging cabinet 20 also includes guardrails arranged around the mounting base. There is a certain amount of space left between the guardrail and the battery pack mounting base to facilitate the installation and removal of the external battery pack.

Specifically, as shown in FIG. 24 , in this embodiment, the guardrail includes a first guardrail 461 provided on the front part 221 and a second guardrail 462 provided on the right part of the charging housing 22 . Among them, the first guardrail 461 is arranged around the outside of the two first battery pack mounting seats 34, and the second guardrail 462 is arranged around the outside of the second type battery pack mounting seat 36.

Furthermore, guardrails are usually made of metal materials with high structural strength.

Furthermore, in order to achieve a good anti-collision effect, as shown in FIG. 24 , in the height direction Z of the charging cabinet 20 , the guardrail is configured to cover at least the entire mounting portion of the battery pack mounting base.

Similarly, in order to prevent garden tools from colliding with the battery cabinet 10 and causing damage to the battery cabinet 10 , the second battery case 15 is made of a metal material with high structural strength.

Preferably, the second battery case 15 is made of high-strength steel.

As mentioned above, in the energy storage power supply 100, the charging cabinet 20 and the battery cabinet 10 have different requirements. Specifically: in the charging cabinet 20, the first electrical component has higher requirements for heat dissipation and protection level; the second electrical component has higher requirements for protection level. The battery cabinet 10 has higher requirements for protection level. If two devices are designed into an integrated structure, then, on the premise of meeting their different needs, the overall structure will become very complicated, and the manufacturing The cost will also increase accordingly; and the overall weight of the energy storage power supply 100 with the charging cabinet 20 and the battery cabinet 10 will not be less than 100KG, which makes it quite difficult for the staff to transport and move the energy storage power supply 100.

For this reason, in this embodiment, the charging cabinet 20 and the battery cabinet 10 are constructed as separate structures, and the two are connected through the first input/output interface 16 and the second input/output interface 18 to realize power transmission; thus, Each device can be designed with full consideration of its own needs, simplifying the structure; at the same time, it also reduces the handling burden of the work team.

More importantly, by setting the battery cabinet 10 and the charging cabinet 20 separately, the charging cabinet 20 will no longer be limited to being connected to only one battery cabinet 10 . When the power of the battery cabinet 10 connected to the charging cabinet 20 is insufficient, the charging cabinet 20 can be selectively connected to another battery cabinet 10; in this way, it is equivalent to expanding the battery capacity of the energy storage power supply 100, which can support garden tools for a longer period of time. Time work.

Further, the charging cabinet 20 and the battery cabinet 10 are provided separately, and the charging cabinet 20 is also configured to be able to connect at least two battery cabinets 10 . At this time, the user only needs to connect a certain number of battery cabinets 10 to the charging cabinet 20 in advance to handle other matters, because the electronic control unit itself will control the work of the energy storage power supply 100 according to its set charging logic, including controlling various The battery cabinet 10 supplies power to the charging cabinet 20 , or controls the charging cabinet 20 to supply power to each battery cabinet 10 . When the charging cabinet 20 is only connected to one battery cabinet 10 at a time, the user needs to pay attention to the status of the energy storage power supply 100 at all times. When the battery cabinet 10 is found to have insufficient power, it is necessary to manually replace another battery cabinet 10 to charge the charging cabinet 20; or When using the charging cabinet 20 to charge the battery cabinet 10, when one battery cabinet 10 is found to be fully charged, another battery cabinet 10 needs to be replaced manually. Therefore, the charging cabinet 20 is configured to connect at least one battery cabinet 10. The user does not need to squat next to the energy storage power supply 100 to replace the battery cabinet 10. In terms of user operation, it is only necessary to connect each battery cabinet 10 with the charging machine in the early stage. After the connection work of the cabinet 20, other matters can be completely handled later, making the operation simpler and more efficient.

Specifically, Figures 25 to 27 respectively illustrate three different designs of the charging cabinet 20 connecting two battery cabinets 10.

Referring to Figure 25, in the first design, each battery cabinet 10 is provided with a first input/output interface 16; the charging cabinet 20 is provided with two second input/output interfaces respectively connected to the first input/output interfaces 16. That is to say, the first design realizes the connection between the charging cabinet 20 and multiple battery cabinets 10 by arranging a plurality of second input/output interfaces on the charging cabinet 20 for connecting to the first input/output interfaces 16 of the battery cabinet 10 respectively. Connection.

Referring to Figure 26, in the second design, each battery cabinet 10 is provided with a first input/output interface 16; the charging cabinet 20 is provided with a second input/output interface. In order to connect the two battery cabinets 10 to the charging cabinet 20, The energy storage power supply 100 also includes a battery cabinet management module 50 . The battery cabinet management module 50 is provided with two battery cabinet side interfaces and one charging cabinet side interface matching the number of battery cabinets 10 . Among them, two battery cabinet side interfaces are used to connect to the first input/output interface 16 of the battery cabinet 10 respectively, and one charging cabinet side interface is used to connect to the second input/output interface of the charging cabinet 20 . That is to say, Design 2 connects multiple battery cabinets 10 to one charging cabinet 20 by introducing a battery cabinet management module 50 . The battery cabinet management module 50 is provided with multiple battery cabinet side interfaces corresponding to the number of battery cabinets 10 .

Referring to Figure 27, in the third design, each battery cabinet 10 is provided with a female interface 161 and a male interface 162, and the charging cabinet 20 is provided with a second input/output interface; among them, the male interface 162 is used to communicate with the charging cabinet 20 or the battery. Cabinet 10 is connected, and the female interface 161 is only used to connect with the battery cabinet 10 . Specifically, as shown in Figure 27, the male interface 162 of the battery cabinet 10 located below is connected to the female interface 161 of the battery cabinet 10 located above, and the male interface 162 of the battery cabinet 10 located above is connected to the second input/output of the charging cabinet 20. Output interface, so that the connection between two battery cabinets 10 and the charging cabinet 20 can be realized. That is to say, in the third design, by configuring the battery cabinet 10 to include a male interface 162 and a female interface 161, multiple battery cabinets 10 can be connected to each other to form a "large battery cabinet" before being connected to the charging cabinet 20. , and then connect the "large battery cabinet" with the charging cabinet 20.

It should be noted that when the charging cabinet 20 is connected to at least one battery cabinet 10 and charges external charging components, it does not mean that every battery cabinet 10 participates in the process of providing electric energy to the charging cabinet 20 . Whether the battery cabinet 10 participates and in what order is actually controlled by the aforementioned battery cabinet management module 50 or the electronic control unit of the charging cabinet 20 .

When at least one battery cabinet 10 is connected to the charging cabinet 20 , the charging cabinet 20 can still receive external power through the third input interface 30 or the fourth input interface 32 and charge the at least one battery cabinet 10 through the second input/output interface 18 .

Furthermore, by arranging the charging cabinet 20 and the battery cabinet 10 separately, the charging cabinet 20 can be used as a charger alone. At this time, the external electric energy is transmitted to the charging cabinet 20 through the third input interface 30 or the fourth input interface 32 provided on the charging case 22, and after being converted by the electronic control unit, is output to the external charging component through the output interface, thereby achieving The charging cabinet 20 charges the external charging components.

As shown in Figure 28, a typical working scenario of the energy storage power supply 100 can be described as follows: During the day, when the work team goes out to work, the energy storage power supply 100, along with various garden tools and battery packs 200, are carried by vehicles to the third place. A garden, the garden tools mainly include: push lawn mower 300, hair dryer 400, lawn trimmer 500, pruning machine 600, smart lawn mower 700, etc. When the work of the first garden is completed, the energy storage power supply 100 is then transferred to the second garden, and the cycle continues until all the work is completed. Among them, when the power of the battery pack 200 is exhausted, the battery pack 200 needs to be installed on the energy storage power supply 100 and the energy storage power supply 100 is used to charge it. In the evening, the work team returns to the gardening company or residence, and then charges the energy storage power supply 100 through the mains power.

Consider that the vehicle itself can be parked at any convenient place for work, whether it is outdoors, the energy storage power supply 100 charges the external battery pack, or the battery cabinet 10 is charged through an external power supply, etc., as well as the bulkiness of the energy storage power supply 100. To reduce the burden of relocation, the energy storage power supply 100 is usually placed on the carriage.

In order to ensure the stability of the energy storage power supply 100 when placed in the carriage, avoid collisions caused by vehicle braking and other situations, and reduce the vibration transmitted to the energy storage power supply 100 during transportation, in this embodiment, the energy storage power supply 100 passes The thread is removably mounted to the carriage.

Specifically, referring to Figure 9, a number of fixing plates 160 are arranged at the bottom of the second battery case 15, and the fixing plates 160 are provided with through holes; correspondingly, the compartment is provided with threaded holes. When installing the battery cabinet 10 to the carriage, first align the through hole on the fixing plate 160 with the threaded hole on the carriage; then screw a threaded locking piece through the through hole on the fixing plate 160 into the threaded hole on the carriage. , thereby realizing the detachable connection between the battery cabinet 10 and the compartment.

Of course, in other embodiments, the detachable connection method between the battery cabinet 10 and the carriage is not limited to threaded connection, such as plugging, snapping, splicing, etc., which depends on the actual situation and is not specifically limited here. .

Similarly, as shown in FIG. 11 , the bottom 226 of the charging case 22 is provided with a number of fixing plates 227 , and the fixing plates 227 are provided with through holes. When installing the charging cabinet 20 to the carriage, first align the through hole on the fixing plate 227 with the threaded hole on the carriage; then screw a threaded locking piece through the through hole on the fixing plate 227 into the threaded hole on the carriage. , thereby realizing the detachable connection between the charging cabinet 20 and the vehicle compartment.

Of course, in other embodiments, the detachable connection method between the charging cabinet 20 and the carriage is not limited to threaded connection, such as plugging, snapping, splicing, etc., which depends on the actual situation and is not specifically limited here. .

When the accommodation space of the carriage is limited, especially when the accommodation space in the up and down direction is limited, the charging cabinet 20 and the battery cabinet 10 can be placed in the carriage respectively to perform related work, as shown in Figure 4 . At this time, the charging case 22 and the second battery case 15 are detachably connected to the vehicle compartment through the through holes provided in the fixing plate.

Therefore, by arranging the charging cabinet 20 and the battery cabinet 10 separately, the overall height of the energy storage power supply 100 can be reduced, so that the height dimension of the compartment used to accommodate the energy storage power supply 100 is also more tolerant.

In this embodiment, the first input/output interface 16 is connected to the battery pack 14 through the cable 17. Since the cable 17 can be bent and has a certain length, the distance between the charging cabinet 20 and the battery cabinet 10 can change. Therefore, it can be more flexible when disposing the charging cabinet 20 and the battery cabinet 10 respectively on the vehicle compartment.

When the accommodation space of the carriage is sufficient, especially the accommodation space along the up and down direction is sufficient, the charging cabinet 20 and the battery cabinet 10 can be stacked together in the up and down direction through connecting components to form an integral structure, as shown in FIG. 1 .

Specifically, the connection assembly includes a threaded hole 191 provided on the top of the second battery housing 15 , a threaded locking piece, and a through hole provided on the fixing plate 227 of the charging cabinet 20 . The threaded locking member is screwed into the threaded hole 191 on the top of the second battery case 15 through the through hole, thereby achieving a detachable connection between the battery cabinet 10 and the charging cabinet 20 .

Of course, a fixed plate can also be provided on the upper edge of the second battery case 15. The fixed plate is provided with a threaded hole, and the threaded locking member passes through the through hole provided on the charging case 22 and is then screwed into the threaded hole. Thus, the charging cabinet 20 and the battery cabinet 10 are detachably connected.

In other embodiments, the connection assembly may include a first connection element disposed on one of the charging cabinet 20 and the battery cabinet 10 , and a second connection movably disposed on the other of the charging cabinet 20 and the battery cabinet 10 element; in the connection position, the first connection element and the second connection element engage with each other.

Of course, in other embodiments, the detachable connection method between the battery cabinet 10 and the charging cabinet 20 is not limited to threaded connection, such as plugging, splicing, etc., which depends on the actual situation and is not specifically limited here.

In this embodiment, the length dimension of the battery cabinet 10 is approximately equal to the length dimension of the charging cabinet 20, and the width dimension 10 of the battery cabinet 10 is approximately equal to the width dimension of the charging cabinet 20. Specifically, the length dimension of the battery cabinet 10 is approximately the same as the length dimension of the charging cabinet 20. The ratio of the length dimension of the battery cabinet 20 is between 0.9-1.1; the ratio of the width dimension of the battery cabinet 10 to the width dimension of the charging cabinet 20 is between 0.9-1.2; therefore, when the battery cabinet 10 and the charging cabinet 20 are stacked in the up and down direction When , each side of the battery cabinet 10 is approximately flush with the corresponding side of the charging cabinet 20 , and the battery cabinet 10 and the charging cabinet 20 together form an approximately rectangular parallelepiped configuration, as shown in FIG. 1 .

In other embodiments, the capacity of the battery unit can be further increased to 7kw˙h, or even more; then, it is conceivable that the size of the battery unit will be increased accordingly, and further, the size of the battery cabinet 10 will also be further increased. . In order to ensure the overall consistency or coordination of the battery cabinet 10 and the charging cabinet 20 when they are stacked in the up and down direction, it is chosen to keep the length of the battery cabinet 10 and the charging cabinet 20 basically consistent, and the battery cabinet 10 is The width is further increased. At this time, the ratio of the width of the battery cabinet 10 to the width of the charging cabinet 20 is between 0.9-2.

Therefore, the charging cabinet 20 and the battery cabinet 10 are configured in a stacked manner, making the energy storage power supply 100 smaller and more compact.

In this embodiment, when the charging cabinet 20 and the battery cabinet 10 are placed in a stacked manner, the battery cabinet 10 is usually placed below. This is because the battery cabinet 10 has a greater weight and smaller volume than the charging cabinet 20 , that is, the density of the battery cabinet 10 is greater; the battery cabinet 10 supports the configuration of the charging cabinet 20 , so that the overall energy storage power supply 100 Greater stability.

Further, the opening 154 is provided on the top of the battery case 12, and the second input/output interface 18 is provided on the same side as the opening 154, on the right part 224 of the charging case 22, so that when the first input/output interface 16 is connected to the second input/output interface 18, the first input/output interface 16 and the cable 17 are relatively concentrated in the peripheral area of the second input/output interface 18, so that the first input/output interface 16, the cable 17 and the second The input/output interface 18 can be blocked by the door member 229 provided on the charging housing 22, forming a structure as shown in Figure 1; in this way, the overall energy storage power supply 100 is more concise, and also avoids dust and rain. etc. into the input interface, affecting the life of the device.

In this embodiment, when the battery cabinet 10 and the charging cabinet 20 are stacked in the up and down direction, the battery cabinet 10 is located below and the charging cabinet 20 is located above; and the second input/output interface 18 is provided on the charging cabinet 20, and the first input/output interface 18 is provided on the charging cabinet 20. Interface 16 The cable 17 is arranged on the battery cabinet 10 , and the height of the charging cabinet 20 is greater than the height of the battery cabinet 10 . In this way, when connecting the first input/output interface 16 to the second input/output interface 18, the user has a larger operating space and is more convenient to operate.

In this embodiment, the extension direction of the track of the battery pack mounting base is parallel to the up and down stacking direction of the battery cabinet 10 and the charging cabinet 20; in this way, during the use of the energy storage power supply 100, the insertion and removal of the external battery pack are considered. The operation space coincides with the operation space where the battery cabinet 10 and the charging cabinet 20 are stacked one above the other. Therefore, the energy storage power supply 100 uses a smaller space and the space utilization rate of the vehicle compartment is higher.

Before using the energy storage power supply 100, the user must first realize the mechanical connection and electrical connection between the battery cabinet 10 and the charging cabinet 20.

Specifically, the user needs to stack the battery cabinet 10 and the charging cabinet 20 in the up and down direction first, so that the through holes provided on the charging cabinet 20 are aligned with the threaded holes on the battery cabinet 10; then, pass the threaded locking piece through The through hole is screwed into the threaded hole on the battery cabinet 10 to realize the mechanical connection between the battery cabinet 10 and the charging cabinet 20; finally, the first input/output interface 16 and the second input/output interface 18 are plugged in, Thus, the electrical connection between the charging cabinet 20 and the battery cabinet 10 is achieved.

In order to ensure the alignment of the through holes and the threaded holes and the quickness of stacking up and down, a first fitting part can be designed on the top surface of the battery cabinet 10 and a second fitting part can be designed on the bottom surface of the charging cabinet 20; when stacking up and down, the first fitting part can be designed The fitting part and the second fitting part cooperate with each other, that is, the alignment of the through hole and the threaded hole is achieved.

In this embodiment, the weight of the battery cabinet 10 and the charging cabinet 20 are both greater than 50KG, and the voltage and/or current of the electric energy transmitted between the two are relatively large; if the mechanical connection and the electrical connection are realized in one step , it is difficult to balance security and connection strength. Therefore, with the energy storage power supply provided by this application, the user needs at least two actions to realize the mechanical connection and electrical connection between the charging cabinet 20 and the battery cabinet 10, which is safer and also ensures the connection between the charging cabinet 20 and the battery cabinet 10. connection strength.
