With the acceleration of the pace of life of people, various power tools (such as automatic home appliances, DIY tools and the like) are becoming more popular worldwide, and commercial garden tools are one of them.

Commercial garden-type tools are specialized power tools designed for garden workers or gardeners, commonly referred to as maintenance equipment for landscapes, which typically operate on lawns, hedges, flowers, trees, gardens, etc., and may include one or more of the following tools: grass cutters, lawnmowers, pruners, chain saws, blowers, leaf shredders, snowplows, and the like.

The working power of the commercial garden tool is generally higher, for example, the power of the garden blower is generally 2300W, the power of the mower is generally 2600W, so that the working requirement of the commercial garden tool can be well met by adopting fuel oil as a power source, and the commercial garden tool can be supported to work for a long time. However, the fuel oil tool brings environmental pollution when in use, and the fuel oil tool has larger noise, which is not beneficial to the health of users. Accordingly, alternatives to fuel powered tools have been sought.

Electric power is an environment-friendly, clean and renewable energy source, and electric tools adopting the electric power as a power source are increasingly favored by people. In general, the electric tool is powered by a direct current power supply or an alternating current power supply, but the commercial garden tool usually works outdoors, and the alternating current power supply is difficult to obtain. Therefore, in the field of commercial garden tools, the use of a direct current power supply is more suitable. Preferably, the direct current power supply can be a battery pack, so that the portable electric power device is convenient for a working team to carry around when going out.

The working scenario of a commercial garden-like tool may be described generally as follows: when working team goes out in daytime, the vehicle is used for carrying various garden tools required by the work to various gardens, such as wheeled electric tools of a hand-push mower, an intelligent mower and the like, and hand-held electric tools of a mower, a pruner, a blower and the like; while the work team also needs to carry a dc power supply, such as a battery pack or the like.

When the garden electric tool works, a working team firstly goes to the first garden and works by using various carried garden electric tools. For garden trimming work, mowing work is typically the longest time consuming, and although the lawn sizes are not uniform from household to household, mowing work takes 20-40 minutes on average. Thus, one worker immediately begins mowing with the mower per garden. During mowing, another worker can sequentially complete other types of work by using the handheld electric tool, such as the other worker can mow grass, prune, blow grass again, complete all work almost simultaneously, and then the work team is transferred to the second garden. This is cycled until one day of work is completed.

Therefore, the commercial garden tools have large workload and long working time; if a power tool is to be used instead of a fuel tool, the problem of continuous energy supply of the power tool must be considered.

One solution is to prepare a large number of battery packs to supply power to the electric tools, which undoubtedly brings inconvenience to the outgoing team who originally carries a plurality of different types of garden tools, and has high working cost; another method is to directly charge the battery pack on site by using an outdoor energy storage power supply.

The existing outdoor energy storage power supply is generally used for serving a household user, for example, can serve as a standby power supply during camping, so that the capacity of a stored battery unit is generally not more than 5kw & lt/EN & gt and the output power is generally not more than 100W, and the power requirement of garden tools cannot be met; meanwhile, the output interface of the energy storage power supply is mostly configured as a USB interface or an AC socket and is not matched with the plug-in terminal of the battery pack for the electric tool; more cumbersome, the battery unit and the electric control unit of the existing energy storage power supply are usually placed in the same shell, and the capacity of the energy storage power supply is limited by the capacity of the single battery unit; once the electric quantity of the battery unit is insufficient, the battery unit must be charged first, and the external charging component can be charged by using the energy storage power supply; and the energy storage power supply shell is also provided with an air inlet and an air outlet for external air flow to enter the shell for heat dissipation. The outdoor environment is complex and changeable, and impurities such as rainwater, dust and the like can enter the inside of the shell through the air inlet and the air outlet, pollute the battery unit and the electric control unit, so that the battery unit and the electric control unit cannot work.

Based on the above, the application provides an energy storage power supply, which is characterized in that a battery cabinet and a charging cabinet are arranged in a split mode, and the charging cabinet is selectively connected with at least one battery cabinet, so that the capacity of the energy storage power supply is expanded; moreover, the battery cabinet and the charging cabinet are arranged in a split mode, the design of each cabinet body can completely conform to the characteristic requirements of the battery cabinet, such as the requirement of the battery cabinet on a higher protection level, the requirement of the charging cabinet on a higher heat dissipation level and the like, and the battery cabinet can withstand the test of various outdoor environments; the battery unit has large capacity and high output power, and can supply power for the battery pack of the garden tool for a long time and continuously. When the working team goes out to work, the energy storage power supply, the battery pack and various garden tools can be placed in the vehicle, and the working team can be followed to transfer from one garden to another garden. Because the energy storage power supply stores enough electric energy in advance and can charge the battery pack, the power supply can be supplied to garden tools uninterruptedly by carrying the energy storage power supply and a small amount of battery packs capable of being recycled when a working team goes out, so that a large number of battery packs are not required to be carried, the working team goes out to be convenient to carry, and the use cost is reduced.

As shown in fig. 1 to 4, an energy storage power supply 100 provided by the present application is shown. The energy storage power supply 100 includes a battery cabinet 10 and a charging cabinet 20. The battery cabinet 10 is used for storing direct current electric energy, and the charging cabinet 20 is used for being connected with the battery cabinet 10 so as to convert the received direct current electric energy from the battery cabinet 10 and charge an external charging component through an output interface arranged on the battery cabinet.

For this reason, in the present embodiment, as shown in fig. 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 has a substantially rectangular parallelepiped structure.

In this embodiment, the battery case 12 is configured as a double-case structure, and the first battery case 11 and the second battery case 15 have a space therebetween to form a heat insulating layer, so that the influence of outdoor ambient temperature on the battery cell group can be effectively reduced, for example, the heat transmitted from the sun to the first battery case can be effectively reduced, and the occurrence of dangerous situations such as spontaneous combustion, explosion and the like can be avoided.

Further, the insulating layer is filled with air, which is a hot poor conductor.

Of course, in other embodiments, the insulating layer may be filled with other types of gases, such as nitrogen, etc.

As shown in fig. 9, the opposite side surfaces 151, 152 of the second battery case 15 are also provided with ventilation openings 153 along the length direction X to define a flow path of air inside the second battery case 15, thereby taking away heat generated by the battery cell group 14 during operation.

In the present embodiment, the battery cell group 14 is fixed in the first battery case 11 by a screw locking member, and the first battery case 11 is fixed in the second battery case 15 by a screw locking member.

Of course, the connection between the battery cell group 14 and the first battery case 11 is not limited to the threaded connection, and may be, for example, riveting, welding, or the like, which may be appropriate according to the actual situation, and the present application is not particularly limited herein.

The connection between the first battery case 11 and the second battery case 15 is not limited to the screw connection, and may be, for example, caulking, welding, or the like, as the case may be, and the present application is not particularly limited herein.

In this embodiment, the battery cabinet 10 has a substantially rectangular parallelepiped structure, and has dimensions of about 730mm by 320mm by 200mm in length and width and a weight of not less than 50KG.

In one embodiment, the weight of the battery cabinet 10 is not less than 70KG when the capacity of the battery cell stack 14 is 7 kw.h.

In one embodiment, the battery cell stack 14 may also be a ternary lithium battery. At this time, if the capacity of the battery 14 is 5kw or less, the weight of the battery cabinet 10 is not less than 40KG. When the capacity of the battery 14 is 7 kw.h, the weight of the battery cabinet 10 is not less than 58KG.

In one embodiment, at least one first input/output interface 16 is provided on the battery cabinet 10, the first input/output interface 16 being configured to connect with a second input/output interface 18 provided on the charging cabinet 20 to enable the transfer of electrical energy.

And, the first input/output interface 16 is constructed as a plug structure; correspondingly, the second input/output interface 18 provided on the charging cabinet 20 for connection to the first input/output interface 16 is configured as a socket structure.

Further, as shown in fig. 6, one end of the first input/output interface 16 is fixedly connected to the battery cell group 14 through a cable 17, and the other end is configured to be detachably connected to the second input/output interface 18 of the charging cabinet 20, so as to realize power transmission between the battery cell group 14 and the charging cabinet 20.

In one embodiment, the second input/output interface 18 may have one end fixedly connected to the charging cabinet 20 by a cable and the other end configured to be detachably connected to the first input/output interface 16 of the battery cabinet 10 to enable power transfer between the battery cabinet 10 and the charging cabinet 20. At this time, the first input/output interface 16 is fixedly provided directly on the battery cabinet 10.

In one embodiment, the first input/output interface 16 is directly fixed to the battery cabinet 10, and the second input/output interface 18 is directly fixed to the charging cabinet 20, and a cable assembly is further disposed between the battery cabinet 10 and the charging cabinet 20. The cable assembly includes a cable and an interface disposed at both ends of the cable. One for connection with the first input/output interface 16 and the other for connection with the second input/output interface 18.

In one embodiment, the first input/output interface may also be a receptacle for engaging a plug provided on the charging cabinet 20. In other embodiments, the first input/output interface may also be any suitable connector for electrical connection.

In order to prevent the first input/output interface 16 and the cable 17 from being randomly moved when the battery case 10 is not in use, the first battery case 11 extends downward from the top surface thereof to form a receiving area 111. In the inactive state, the first input/output interface 16 and the cable 17 are housed in the housing area 111.

Correspondingly, an opening 154 is disposed at a position of the second battery housing 15 corresponding to the receiving area 111. Through the opening 154, the first input/output interface 16 is exposed. In operation, the first input/output interface 16 may extend from the opening 154 to connect with the second input/output interface 18.

The second electrical assembly includes a switch module 24 and a control board 26. The switch module 24 may include, among other things, relays, fuses, etc.

The working principle of the electric control unit can be simply described as: when an external charging component is connected to an output interface provided on the charging cabinet 20, the control board 26 may control the relay 24 to be closed, so that external electric energy received by the charging cabinet 20 via the input interface can be transmitted to the power converter, which in turn converts the power converter into a desired current and voltage form and then outputs the converted electric energy from the output interface to the external charging component.

In the electronic control unit, the power converter is larger in size than the switch module 24 and the control board 26. How the power converter is arranged will then directly affect the structural design and the physical dimensions of the charging housing 22.

In the present embodiment, as shown in fig. 15, in order to simplify the structure inside the charging case 22 and to optimize the external dimensions of the charging case 22, the first power converter 17, the second power converter 18, and the third power converter 19 extend along the same plane. Here, the extension plane is defined as a first plane.

Of course, in other embodiments, the type and number of the power converters may be set accordingly according to the actual output current and output voltage, for example, a DC/AC power converter may be set to convert the DC power received by the charging cabinet 20 into AC power to charge the external charging component; for example, only 1 power converter may be provided; or at least one power converter may be integrated on one power conversion assembly, as the application is not limited in this regard.

Referring to fig. 11 to 14, the charging housing 22 has a substantially rectangular parallelepiped structure, and has a front portion 221, a rear portion 222, a left portion 223, a right portion 224, a top portion 225, and a bottom portion 226; wherein the front 221 and rear 222 portions are parallel to the first plane.

Further, the top 225, the bottom 226, the left 223 and the right 224 are integrally formed to form a housing body together, and the front 221 and the rear 222 are detachably connected to the housing body through threaded fasteners, respectively, so as to facilitate the assembly and maintenance of the electronic control unit disposed inside the charging housing 22 by a user.

Referring to fig. 13 to 14, the charging housing 22 forms a receiving chamber, and a partition 220 is disposed in the charging housing 22 to divide the receiving chamber into a first chamber 1 and a second chamber 2; wherein the charging housing 22 is provided with a vent communicated with the first chamber 1, and the second chamber 2 is arranged in a sealing way. The first electrical component is housed in the first chamber 1, and the second electrical component is housed in the second chamber 2.

Specifically, the vent includes an air inlet 3 provided on one of the right portion 224 and the left portion 223 of the charging housing 22, and an air outlet 4 provided on the other of the right portion 224 and the left portion 223 of the charging housing 22. A fan 5 is further disposed in the first chamber 1, and the fan 5 is configured to draw external air into the first chamber 1 through the air inlet 3, and flow out of the first chamber 1 through the air outlet 4 after flowing through the first electrical component.

Further, a screen or a grid (not shown) may be provided on the air inlet 3 and the air outlet 4 to prevent larger dust or foreign matters from entering the first chamber 1.

Further, louvers may be provided on the air inlet 3 and the air outlet 4 to prevent rainwater from entering the first chamber 1.

According to the technical scheme provided by the application, the first chamber 1 and the second chamber 2 are formed in the charging shell 22, the first chamber 1 is provided with a vent hole, and the second chamber 2 is arranged in a sealing manner. While a first electric component having a large heat generation amount is housed in the first chamber 1, and a second electric component having a small heat generation amount is housed in the second chamber 2. By the arrangement, the heat dissipation requirement of the first electric component and the protection requirement of the second electric component are fully considered.

Therefore, the charging cabinet 20 provided by the application not only can well radiate heat of electronic devices with large heating value, but also can seal and protect electronic devices with high protection requirements, so that the charging cabinet 20 can stably work in a severe environment.

In order to further improve the protection level of the first electric component, the first electric component in the first chamber 1 can be independently packaged to avoid the situation that the first electric component cannot work normally due to contact with rainwater, dust and the like.

Specifically, the charging cabinet 20 further includes an enclosure that encloses each power converter. The enclosure may be made of an aluminum alloy, which has good heat conduction efficiency. As such, each power converter has a protection level of at least IP67.

Therefore, the technical scheme provided by the application can improve the protection level of each power converter in the first electric assembly by independently packaging the power converters while enabling the first electric assembly with large heat productivity to dissipate heat, so that the power converters are suitable for various severe environments.

Further, a heat radiation fan is provided corresponding to each package box, and the heat radiation fan is provided outside the package box for radiating heat from the package box. When the cooling fan rotates, the air flow in the first chamber 1 is blown to the surface of the packaging box, and the packaging box is cooled. Fig. 15 shows that the first power converter 17 is packaged in a package box 171, and the outside of the package box 171 is provided with a heat radiation fan 7.

Further, in order to secure the shielding performance of the second chamber 2, as shown in fig. 16, a sealing member 27 is further provided at the edge of the rear portion 222, and the rear portion 222 is sealed with the housing body by the sealing member 27.

In the present application, the protection level of the second chamber 2 is at least IP55.

As previously described, the switch module 24 and the control board 26 in the second chamber 2 need to be in electrical communication with the respective power converters in the first chamber 1, so that when the external charging member is connected to the output interface, the control board 26 can control the relay 24 to close so that the electrical energy received by the input interface can be transmitted to the power converters, which in turn are converted into the required current and voltage forms and output from the output interface to the external battery pack.

For this purpose, the partition 220 is provided with a through hole for communicating the first chamber 1 and the second chamber 2, and an electrical communication module for blocking the through hole is provided in the through hole, and the second electrical component is electrically connected to the first electrical component through the electrical communication module.

Specifically, as shown in fig. 13 to 16, the separator 220 is provided with a first through hole 227 and a first through hole 228, the first through hole 227 is provided with a first electrical communication module 23 therein, and a seal member may be provided between the first electrical communication module 23 and the first through hole 227; a second electrical communication module 25 is disposed within the second through hole 228, and a seal may be disposed between the second electrical communication module 25 and the second through hole 228. Wherein the first electrical communication module 23 may be a partial structure on the switch module 24, which is inserted into the first through hole 227 to perform electrical energy transmission with the power converter in the first chamber 1; the second electrical communication module 25 may be a plug that is inserted into the second through hole 228 and may be used to enable the power converter in the first chamber 1 to communicate signals with the switch module 24 and the control board 26 in the second chamber 2 through the plug.

Optionally, at least a portion of the first electrical component and at least a portion of the second electrical component are disposed on the spacer 220, supported by the spacer 220; this can simplify the structure of the housing body on the one hand and save space on the other hand.

Specifically, as shown in fig. 15, in the first chamber 1, the first power converter 17, the second power converter 18, and the third power converter 19 are sequentially disposed on the partition 220, and supported by the partition 220. And, the common extension plane of the 3 power converters, i.e., the first plane, is precisely the plane in which the partition 220 is located. In the second chamber 2, at least part of the switch module 24 and the control board 26 are disposed on the partition 220.

In order to improve the supporting performance of the separator 220, the separator 220 is made of a metallic material having high structural strength.

In the present embodiment, the partition 220 is integrally formed with the housing body.

Of course, in one of the embodiments, the rear portion may be integrally formed with the top, bottom, left and right portions, together forming the housing body. And a partition is removably disposed within the housing body to divide the receiving chamber into a first chamber and a second chamber.

Of course, in one of the embodiments, the charging housing may be provided with only one chamber, which is provided in a sealed manner, with a higher protection level, and which houses the first and second electrical components. At this time, at least one power converter is supported by the rear of the charging housing. At least one of the power converters still extends along the same plane, which extends parallel to the front portion. The heat dissipation module for the power converter is arranged outside the rear part.

In one embodiment, the charging cabinet 20 further includes an input interface module 28 disposed on the charging housing 22. The charging cabinet 20 receives external power via the input interface module 28 so that the electronic control unit converts the received external power to charge the external charging member.

Specifically, as shown in fig. 17, in the present embodiment, the input interface module 28 is integrated on the right portion 224 of the charging housing 22, and includes the second input/output interface 18 for connection with the first input/output interface 16 provided on the battery cabinet 10. The second input/output interface 18 correspondingly includes a positive power supply terminal, a negative power supply terminal and a number of signal terminals.

In the present embodiment, the second input/output interface 18 is configured as a socket.

In addition to the second input/output interface 18, the input interface module 28 also includes a third input interface 30 and a fourth input interface 32.

In particular, the third input interface 30 is configured as an ac input interface for connecting an external ac power source, for example, mains, so that the charging cabinet 20 can charge the battery cabinet 10 and the external charging components by means of the mains.

Typically, the amount of power stored by the energy storage power source 100 can be sufficient for a work team to work for one day outside. Thus, at night rest, the stored energy power source 100 may be brought back to residence and the battery cabinet 10 and the plurality of external charging components connected to the charging cabinet 20 may be charged with mains electricity.

When the energy storage power supply 100 is charged by the utility power at night, the utility power charges the battery cabinet 10 in the energy storage power supply 100 preferentially, and after the battery cabinet 10 is full, the utility power 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, for example, an on-board solar power source, so that the charging cabinet 20 can charge the battery cabinet 10 and external charging components by solar energy when going out.

In the present embodiment, when the external charging member is connected to the energy storage power supply 100, the solar power supply charges the external charging member preferentially, and charges the battery box 10 after the external charging member is fully charged.

In the present embodiment, the third input interface 30 and the fourth input interface 32 are each configured as a unidirectional interface; that is, the third input interface 30 and the fourth input interface 32 each function to input external power to the charging cabinet 20; while the second input/output interface 18, as well as the first input/output interface 16 provided on the battery cabinet 10, are each configured as a bi-directional interface; that is, the power transmission between the battery cabinet 10 and the charging cabinet 20 is bidirectional, and not one side can only supply power and the other side can only receive power.

Specifically, when the battery cabinet 10 is used to supply the charging cabinet 20 with dc power and charge the external charging components, the first input/output interface 16 exists as an output interface for the battery cabinet 10; similarly, the second input/output interface 18 is present as an input interface for the charging cabinet 20.

When the charging cabinet 20 is connected to external power through the third input interface 30 or the fourth input interface 32 and charges the battery cabinet 10, the first input/output interface 16 becomes an input interface for the battery cabinet 10, and the second input/output interface 18 is an output interface for the charging cabinet 20.

It should be noted that whether the interface is an input interface or an output interface is not determined by the structure of the interface itself, but is controlled by charging logic of an electronic control unit provided in the charging cabinet 20.

When the working team works outside, the charging cabinet 20 can receive the vehicle-mounted solar power supply to charge the battery cabinet 10 and the external charging component, and can also be connected with a power battery carried by the electric automobile to charge the battery cabinet 10 and the external charging component.

In this embodiment, the input interface module 28 includes a second input/output interface 18 and a fourth input interface 32 configured for direct current electrical energy input, and a third input interface 30 configured for alternating current electrical energy input; in this way, the energy storage power supply 100 can charge the battery cabinet 10 or the external charging component through direct current electric energy, and can charge the battery cabinet 10 or the external charging component through alternating current electric energy, so that the use scene of the energy storage power supply 100 is enriched.

As shown in fig. 3, a door member 229 is further provided on the charging housing 22, and the door member 229 is detachably connected to the charging housing 22, so that a closed state shielding the input interface module 28 can be formed.

In the closed state, the input interface module 28 is sealed from the outside through the door member 229, thereby avoiding damage to the interface by external rainwater and dust and prolonging the service life of the device.

In one embodiment, the charging cabinet 20 is provided with at least one battery pack mounting for detachably connecting an external battery pack for charging thereof.

Specifically, referring to fig. 11, in the present embodiment, the battery pack mount includes a first type of battery pack mount 34 disposed on the front 221 and a second type of battery pack mount 36 disposed on the right 224 of the charging housing 22. The first type battery pack mounting seat 34 is used for detachably connecting the first type battery pack 201, and the second type battery pack mounting seat 36 is used for detachably connecting the second type battery pack 203, wherein the capacity of the first type battery pack 201 is larger than that of the second type battery pack 203.

Specifically, as shown in fig. 18 to 19, the first-type battery pack 201 has a capacity of 0.6kw 2 h and a weight of about 7.9KG; the second type of battery pack 203 has a capacity of 0.24 kw/h and a weight of about 2.8KG. The first type of battery pack 201 is primarily used to power large and/or high power tools, such as a hand propelled mower 300, a blower 400, and the like. The second type of battery pack 203 is used to power hand-held power tools such as the lawnmower 500 and the pruner 600.

As shown in fig. 20, the first type of battery pack mount 34 includes: a base 341, a mounting portion 342, an output interface 343, and a locking device. The above-described structures will be described in relation to each other.

A base 341 for connecting with the front 221 to mount the first type battery pack mount 34 to the charging housing 22. Specifically, the base 341 is provided with a plurality of threaded holes, and the inner wall of the front 223 is correspondingly provided with screws matched with the threaded holes.

When the first type battery pack mounting seat 34 is mounted, firstly, the screw rod of the front part 223 passes through the threaded hole of the first type battery pack mounting seat 34, and the mounting part 342, the output interface 343 and the like protrude from the opening of the front part 223; finally, the front portion 223 is fixed to the base portion 341 by a nut.

The mounting portion 342, protruding the base portion 341, is provided including a first type of rail 342a and a second type of rail 342b. The first type rail 342a is used to cooperate with the mounting rail of the first type battery pack 201 to detachably and slidably connect the charging cabinet 20 with the first type battery pack 201; the second-type rail 342b is adapted to cooperate with a mounting rail of the second-type battery pack 203 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 are of a double-rail structure, respectively, and one first type rail 342a and one second type rail 342b share one supporting portion.

The output interface 343 is matched with the charge-discharge 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 quincuncial contacts, and correspondingly, the output interface 343 uses inserting pieces corresponding to the quincuncial contacts.

Specifically, as shown in fig. 21, the output interface 343 includes a positive electrode tab 3431, a negative electrode tab 3432, an analog signal communication tab 3433, a first digital signal communication tab 3434, and a second digital signal communication tab 3435. Wherein the second digital signal communication insert sheet 3435 comprises two insert sheets 3435a and 3435b, respectively, which are insulated from each other.

In the process of moving the vehicle, the conditions of braking, jolting and the like are unavoidable. In order to prevent the external battery pack from slipping out of the battery pack mounting seat and falling down due to vibration of the vehicle, the battery pack mounting seat of the embodiment further comprises a locking device under the condition that the external battery pack is damaged. The locking device is used for locking the connection state of the external battery pack and the battery pack mounting seat, specifically, please refer to fig. 20, 22a and 22b.

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

Here, when no external force is applied, the lock catch 3441 is defined as a natural position; the lock 3441 is moved rearward against the urging force of the first spring 38 when it is subjected to an external force, and is in a retracted position.

Next, the operation principle of the lock catch 3441 and the unlock button 3442 will be described taking a process of attaching the external battery pack to the battery pack mount and removing the battery pack from the battery pack mount as an example.

Referring to fig. 20, when it is desired to charge an external battery pack, the battery pack is mounted to the battery pack mounting base along the first type rail 342a from top to bottom; at this time, the lock catch 3441 moves backward to the retracted position shown in fig. 22b by the abutment action of the battery pack; when the battery pack is mounted in place, the catch 3441 is restored to the natural position shown in fig. 22a by the first spring 38 and is engaged with the locking portion of the battery pack, thereby mounting the external battery pack to the battery pack mounting base 34.

When the battery pack needs to be removed, the worker needs to press the unlocking button 3442 against the elastic force of the second spring 40; the lower end of the unlocking button 3442 abuts against the lock catch 3441 to drive the lock catch 3441 to move backwards, so that the lock catch 3441 is separated from the locking part of the battery pack; to this end, the lock of the external battery pack is released, which can slide out from the first-type rail 342 a.

In the energy storage power supply 100 of the present embodiment, the charging cabinet 20 has a large charging current for the external battery pack. If the battery pack accidentally slips out of the battery pack mounting seat in the charging process, or if the charging is not completed, the user needs to use an external battery pack to slip the battery pack out of the battery pack mounting seat, and the electrode plate can be ignited due to charging current, and then ablated, so that the battery pack cannot work normally. For this reason, in the unlocking device of the present embodiment, when the user presses the unlocking button 3442, an electronic switch is triggered. The electronic switch is used to disconnect the charging circuit of the charging cabinet 20 to an external battery pack connected to the battery pack mount. When the user releases the unlocking button or reaches a predetermined time, the electronic switch is restored to turn on the charging circuit of the battery pack mounting base to the external battery pack mounted thereon.

In this embodiment, the first-type battery pack mount 34 is also configured to detachably connect to the second-type battery pack 203. For this reason, the mounting portion 342 is designed to include two types of rails, the first type of rails 342a is used for detachably connecting the first type of battery pack 201, and the second type of rails 342b is used for detachably connecting the second type of battery pack 203, so that the first type of battery pack mounting seat 34 can charge both the first type of battery pack 201 and the second type of battery pack 203 under the condition of sharing the output interface 343 and the locking device, thus simplifying the structure and improving the suitability of the first type of battery pack mounting seat 34.

The second type battery pack mounting base 36 has a similar structure to the first type battery pack mounting base 34, and includes a second type rail, an output interface and a locking device, and the second type rail, the output interface and the locking device have the same structure, relative positions, dimensions and actions as those of the first type battery pack mounting base 34, except that the second type battery pack mounting base 36 is only provided with the second type rail, and only the second type battery pack can be mounted.

In the present embodiment, the extending direction of the first type rail 342a and the second type rail 342b is parallel to the vertical direction, that is, the sliding direction of the external battery pack is parallel to the vertical direction. The external battery pack can be easily slid into the battery pack mounting seat by utilizing the self gravity of the external battery pack on one hand, and a user does not apply more force; on the other hand, the rail is arranged along the vertical direction, so that the use space of the energy storage power supply 100 can be further saved, and the use rate of the carriage is improved. This is because, in the process of inserting and extracting the battery pack, it is necessary to consider that a certain space is reserved in the slip direction of the battery pack, which can also be said to be the use space of the energy storage power supply 100. The track is arranged in the vertical direction, and occupies only the space above the energy storage power supply 100, and the space above the energy storage power supply 100 is abundant. If the first type rail 342a or the second type rail 342b is designed to extend in the horizontal direction or the oblique direction, a certain amount of space for the sliding of the external battery pack must be reserved in the horizontal direction, which necessarily occupies the space on the compartment that may be used for placing a mower or a grass mower.

In this embodiment, as shown in fig. 4, the battery pack mounting seat further includes a second air inlet 6 communicating with the first chamber 1. The second air intake 6 is designed to: when the battery pack is connected to the external battery pack, the second air inlet 6 will be in butt joint with the air flow outlet of the external battery pack. So set up, when the fan that is located the inside of cabinet 20 that charges works, outside air will get into the inside of battery package from the air inlet of battery package, for the air outlet of battery package after the heat dissipation of battery package, second air intake 6 gets into the inside of first cavity 1 to finally to the air outlet outflow of cabinet 20 that charges.

Therefore, in the charging cabinet 20 of the present embodiment, the air inlet 6 communicating with the first chamber 1 is provided on the battery pack mounting seat, and the air inlet 6 is abutted to the air flow outlet of the external battery pack, so that the fan can radiate heat not only for the first electrical component contained in the first chamber 1, but also for the external battery pack connected thereto, thereby improving the heat radiation efficiency of the external battery pack.

In the present embodiment, the charging cabinet 20 is provided with 3 battery pack mounting seats in total, two first-type battery pack mounting seats 34 provided on the front portion 221, and one second-type battery pack mounting seat 36 provided on the right portion 224 of the charging housing 22, respectively. Wherein 2 first-type battery pack receptacles 34 are configured to charge either the first-type battery pack 201 or the second-type battery pack 203; the 1 second-type battery pack 36 mount is configured to charge the second-type battery pack 203; by the arrangement, the charging cabinet 20 can charge a plurality of battery packs with different capacities at the same time at night, so that the charging efficiency is improved, and a working team can conveniently carry the battery packs with enough electric quantity to go out to work in daytime.

Further, since the front 221 of the charging housing 22 is parallel to the extension plane of the power converter, that is, in each side of the charging housing 22, the front 221 is larger in size; the 2 first type battery pack mounts 34 are disposed on the front 221 of the housing 22 and the 1 second type battery pack mounts 36 are disposed on the right 224 of the housing 22 to better fit the structural dimensions of the charging housing 22 itself. In this way, the battery pack mounting seats satisfying the long-time work demands of the garden team can be arranged on both sides of the charging case 22, and the structure of the energy storage power source 100 is more compact.

Further, the power provided to the external battery pack by the charging cabinet 20 may also be understood as the power received by the charging cabinet 20 via the input interface is converted into the specific current and voltage form of the power through the power converter, and the battery pack mounting seat is disposed close to the first chamber 1, that is, the battery pack mounting seat is disposed close to the power converter, so that the circuit wiring between the electronic control unit of the charging cabinet 20 and the battery pack mounting seat is simplified.

In this embodiment, the input interface module 28 and the second type battery pack mount 36 are both disposed on the right portion 224 of the charging housing 22; the arrangement meets the operation habit of the right hand of the user, and the charging interface module 28 and the second type battery pack mounting seat 36 are arranged on the same side, so that a part of operation space can be shared, and the space occupied by the energy storage power supply 100 in use is saved.

Further, the air outlet 4 is provided on the left portion 223 of the charging housing 22 instead of the right portion 224, so that adverse effects of the hot air flowing out from the first chamber 1 on the second-type battery pack 203 mounted on the second-type battery pack mount 36 can be effectively avoided.

To facilitate a user's visual understanding of the charge status of the external battery packs connected to the respective battery pack mounting bases and whether a malfunction has occurred, an indicator light 42 is provided near each battery pack mounting base. The indicator light 42 indicates different states of charge by color and flashing frequency. The indication of the charging state by the color and the blinking frequency of the indicator light is a common technique in the charger field, and will not be described here too much.

In order to match the high power requirement of the commercial garden tools, the direct current power supply for supplying electric energy to the commercial garden tools, namely the capacity and the weight of the battery pack are large. As mentioned above, the weight of the first type of battery pack 201 may be up to 7.9KG and the weight of the second type of battery pack 203 may be up to 2.8KG, in order to avoid that after mounting the first type of battery pack 201 or the second type of battery pack 203 to the charging cabinet 20, a tilting of the charging cabinet 20, in particular in the width direction of the charging cabinet 20, is caused, the charging cabinet 20 of the present embodiment is arranged such that:

In the present embodiment, the front portion 221, the rear portion 222, and the partition 220 are parallel to each other; and, the distance between the diaphragm 220 and the rear portion 222 is smaller than the distance between the diaphragm 220 and the front portion 221. Therefore, when the charging housing 22 is made of the same metal material, the center of gravity of the charging housing 22 itself is disposed closer to the rear portion 222.

Further, most of the electronic control units are disposed on the partition 220 and supported by the partition 220. Therefore, in a state in which the charging cabinet 20 is not connected to an external battery pack, the center of gravity of the charging cabinet 20 itself is disposed closer to the rear portion 222, that is, the center of gravity of the charging cabinet 20 itself is disposed farther from the first-type battery pack mount 34.

In this embodiment the weight of the charging cabinet 20 is at least 50KG in the state in which no external battery pack is connected to the charging cabinet 20. The plane in which the front 221 is defined as a first plane M and the plane in which the rear 222 is defined as a second plane N.

When the first-type pack mount 34 is connected to the external pack, the center of gravity of the whole formed by the charging cabinet 20 and the external pack together will move toward the front 221 in the width direction Y; but because of the self-weight of the charging cabinet 20, its own center of gravity is disposed closer to the rear 222; therefore, even if the external battery pack is connected, the center of gravity of the whole of the charging cabinet 20 and the external battery pack falls in the space defined by the first plane M and the second plane N, and the charging cabinet 20 and the external battery pack do not fall.

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 resulting from the mounting thereof to the charging cabinet 20 is correspondingly greater than the probability of the charging cabinet 20 tipping over resulting from the mounting of the second-type battery pack 203 to the charging cabinet 20. Therefore, next, the example of mounting the different number of the first-type battery packs 201 to the charging cabinet 20 will be described, roughly illustrating the influence of the external battery packs on the center of gravity of the charging cabinet 20.

As shown in fig. 23, in a state in which 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 in the width direction Y of the charging cabinet 20. In a state where only one of the 2 first-type battery pack mounting seats 34 is connected with the first-type battery pack 201, the center of gravity of the whole formed by the charging cabinet 20 and the first-type battery pack 201 in the width direction Y falls at the point B; in a state where the first-type battery pack 201 is connected to each of the 2 first-type battery pack mounting bases 34, the center of gravity of the whole formed by the charging cabinet 20 and the first-type battery pack 201 falls at point C in the width direction Y of the charging cabinet 20. Points A, B and C all fall in the space defined by the first plane M and the second plane N.

In the present embodiment, the second-type battery pack mounting seat 36 is provided centrally on the right portion of the case 22 in the width direction Y of the charging cabinet 20. Therefore, the second-type battery pack mounting base 36 is connected to the external battery pack or not, or the weight of the external battery pack mounted to the second-type battery pack mounting base 36 does not cause the toppling of the charging cabinet 20 in the width direction. Therefore, only the influence of the first-type battery pack mount 34 provided on the front 221 on the center of gravity of the entire charging cabinet 20 when the external battery pack is connected will be discussed herein.

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 2, and are pivotally provided on the charging housing 22 in the horizontal direction X, respectively. When the charging cabinet 20 is in the carrying state, the handle 21 is pivoted to be perpendicular to the top 225 of the charging shell 22, so that the charging cabinet is convenient to grasp; when the charging cabinet 20 is in normal use, the handle 21 is pivoted into a recess provided in the top 225 so as not to protrude beyond the top surface of the charging housing 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 44 displays the state of charge of each battery pack currently connected to the battery pack mount in digital form, for example, the current charge information may be displayed in percentage form. As shown in fig. 2, an operation member is also provided on the display screen 44. The operation members include a first operation key 441 and a second operation key 442. The first operation key 441 is a start key, and when the start key 441 is pressed, the energy storage power supply 100 enters a waiting working state from a rest state; the second operation key 442 is a quick charge mode selection key. When the operation key 442 is pressed, the stored energy power source 100 enters the quick charge mode.

The stored energy power supply 100 is mounted on a carriage during normal operation, and may include garden-type tools such as smart mowers, hand-propelled mowers, and the like. In order to prevent the garden-type tool from colliding with the first-type battery pack 201 or the second-type battery pack 203 mounted to the charging cabinet 20, the charging cabinet 20 further includes a guardrail provided at the periphery of the mount base. The guardrail and the battery pack mounting seat leave a certain space so as to facilitate the mounting and dismounting of the external battery pack.

Specifically, as shown in fig. 24, in the present embodiment, the rail includes a first rail 461 provided on the front portion 221 and a second rail 462 provided on the right portion of the charging housing 22. The first guard rail 461 is disposed around the outer sides of the 2 first battery pack mounting bases 34, and the second guard rail 462 is disposed around the outer sides of the second battery pack mounting bases 36.

Further, guardrails are often made of metallic materials with high structural strength.

Further, in order to achieve a good collision preventing effect, as shown in fig. 24, in the height direction Z of the charging cabinet 20, the guard rail is configured to cover at least the entire mounting portion of the battery pack mounting seat.

Also, in order to prevent the garden-type tool from colliding with the battery case 10, causing damage to the battery case 10, the second battery case 15 is made of a metallic material having high structural strength.

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

As described above, in the energy storage power supply 100, the requirements of the charging cabinet 20 and the battery cabinet 10 are different. The method comprises the following steps: in the charging cabinet 20, the first electrical component has higher requirements on heat dissipation and protection level; the second electrical component has a high protection rating. And the battery cabinet 10 has a high protection level. If the two devices are designed into an integrated structure, the whole structure becomes very complex on the premise of meeting different requirements, and the manufacturing cost is correspondingly increased; also, the total weight of the stored energy power source 100 with the charging cabinet 20 and the battery cabinet 10 will be not less than 100KG, which makes it quite laborious for the staff to handle and move the stored energy power source 100.

For this reason, in the present embodiment, the charging cabinet 20 and the battery cabinet 10 are constructed in a split structure, and both are connected through the first input/output interface 16 and the second input/output interface 18 to achieve transmission of electricity; therefore, each device can make a matched design under the condition of fully considering the self requirements, and the structure is simplified; meanwhile, the carrying burden of a working team is reduced.

More importantly, by providing the battery cabinet 10 separately from the charging cabinet 20, the charging cabinet 20 will no longer be limited to being connected to only a single battery cabinet 10. When the electric quantity of the battery cabinet 10 connected with the charging cabinet 20 is insufficient, the charging cabinet 20 is optionally connected with another battery cabinet 10; thus, the battery capacity of the energy storage power supply 100 is expanded, and the garden tool can be supported to work for a longer time.

Further, the charging cabinet 20 is provided separately from the battery cabinets 10, and the charging cabinet 20 is also configured to be connectable with at least 2 battery cabinets 10. At this time, the user only needs to connect a certain number of battery cabinets 10 with the charging cabinets 20 in advance, so that other transactions can be processed, because the electric control unit itself can control the operation of the energy storage power supply 100 according to the set charging logic, including controlling the power supply of each battery cabinet 10 to the charging cabinet 20, or controlling the power supply of the charging cabinet 20 to each battery cabinet 10. In the case that the charging cabinet 20 is connected with only one battery cabinet 10 at a time, the user needs to pay attention to the state of the energy storage power supply 100 all the time, and when the battery cabinet 10 is found to have insufficient electric quantity, the user needs to manually replace another battery cabinet 10 to charge the charging cabinet 20; or when the battery cabinets 10 are charged by the charging cabinet 20, it is necessary to manually replace one battery cabinet 10 when the battery cabinet 10 is found to be full. Therefore, the charging cabinet 20 is configured to be connected with at least 1 battery cabinet 10, so that a user does not need to squat at any time to replace the battery cabinets 10 beside the energy storage power supply 100, and in terms of user operation, the user only needs to connect each battery cabinet 10 with the charging cabinet 20 in the early stage, and other matters can be completely processed in the later stage, so that the operation is more concise and efficient.

In particular, fig. 25 to 27 respectively illustrate 3 different designs of the charging cabinet 20 to which 2 battery cabinets 10 are connected.

Referring to fig. 25, in design one, each battery cabinet 10 is provided with a first input/output interface 16; the charging cabinet 20 is correspondingly provided with 2 second input/output interfaces for respectively connecting with the first input/output interfaces 16. That is, a connection of the charging cabinet 20 to a plurality of battery cabinets 10 is realized by providing a plurality of second input/output interfaces for connection with the first input/output interfaces 16 of the battery cabinets 10, respectively, on the charging cabinet 20.

Referring to fig. 26, in design two, 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, and the energy storage power supply 100 further includes a battery cabinet management module 50 for connecting 2 battery cabinets 10 to the charging cabinet 20. The battery cabinet management module 50 sets 2 battery cabinet side interfaces and one charging cabinet side interface in accordance with the number of the battery cabinets 10. Wherein 2 battery cabinet side interfaces are for connecting 16 with a first input/output interface of the battery cabinet 10, respectively, and 1 charging cabinet side interface is for connecting with a second input/output interface of the charging cabinet 20. That is, the plurality of battery cabinets 10 are designed to be connected to one charging cabinet 20 by introducing one battery cabinet management module 50. The battery cabinet management module 50 provides a plurality of battery cabinet side interfaces corresponding to the number of battery cabinets 10.

Referring to fig. 27, in design three, 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; wherein the male interface 162 is used for connection with the charging cabinet 20 or the battery cabinet 10, and the female interface 161 is used only for connection with the battery cabinet 10. Specifically, as shown in fig. 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 interface of the charging cabinet 20, so that connection of 2 battery cabinets 10 to the charging cabinet 20 can be achieved. That is, in design three, by providing the battery cabinet 10 to include a male interface 162 and a female interface 161, a plurality of battery cabinets 10 may be connected to each other to form a "large battery cabinet" before being connected to the charging cabinet 20, and then the "large battery cabinet" is connected to 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 an external charging member, it does not mean that each battery cabinet 10 participates in the process of supplying electric power to the charging cabinet 20. Whether and in what order the battery cabinets 10 participate is controlled in fact by the aforementioned battery cabinet management module 50 or by 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 may 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.

Further, by providing the charging cabinet 20 separately from the battery cabinet 10, the charging cabinet 20 can be used alone as a charger. At this time, external electric power is transmitted to the charging cabinet 20 through the third input interface 30 or the fourth input interface 32 provided on the charging housing 22, and is output to the external charging part through the output interface after being converted by the electronic control unit, whereby charging of the external charging part by the charging cabinet 20 is achieved.

As shown in fig. 28, a typical operating scenario of the stored energy power supply 100 may be described as: during daytime, the work team goes out to work, the energy storage power supply 100 is carried to the first garden by the vehicle along with various garden-like tools and the battery pack 200, wherein the garden-like tools mainly comprise: a hand propelled mower 300, a blower 400, a mower 500, a pruner 600, an intelligent mower 700, etc. When the first job is completed, the stored energy power supply 100 is then diverted to the second garden, and so on, until all jobs are completed. When the battery pack 200 is exhausted, the battery pack 200 is mounted to the energy storage power source 100, and the energy storage power source 100 is used to charge the battery pack. At night, the work team returns to the garden company or residence and charges the energy storage power supply 100 with the utility power.

Considering the situation that the vehicle itself may be parked at any convenient place, whether it is outdoors, the energy storage power source 100 charges the external battery pack or charges the battery cabinet 10 through the external power source, and the moving load caused by the bulkiness of the energy storage power source 100, the energy storage power source 100 is usually placed on the cabin.

In order to ensure the stability of the energy storage power supply 100 placed in the compartment, avoid collisions due to conditions such as vehicle braking, and reduce vibrations transmitted to the energy storage power supply 100 by the vehicle during transportation, in this embodiment, the energy storage power supply 100 is detachably mounted to the compartment through threads.

Specifically, referring to fig. 9, a plurality of fixing plates 160 are disposed at the bottom of the second battery case 15, and the fixing plates 160 are provided with through holes; correspondingly, the carriage is provided with a threaded hole. When the battery cabinet 10 is mounted to the vehicle cabin, the through holes on the fixing plate 160 are aligned with the screw holes on the vehicle cabin first; a threaded locking member is threaded through the through hole in the fixing plate 160 into the threaded hole in the compartment, thereby achieving a detachable connection of the battery cabinet 10 to the compartment.

Of course, in other embodiments, the detachable connection between the battery cabinet 10 and the compartment is not limited to the threaded connection, such as plugging, buckling, splicing, etc., and is not specifically limited herein according to the actual situation.

Similarly, as shown in fig. 11, the bottom 226 of the charging housing 22 is provided with a plurality of fixing plates 227, and the fixing plates 227 are provided with through holes. When the charging cabinet 20 is mounted to the vehicle cabin, the through holes on the fixing plate 227 are aligned with the screw holes on the vehicle cabin first; and a threaded locking member is screwed into the threaded hole in the carriage through the through hole in the fixing plate 227, thereby realizing the detachable connection of the charging cabinet 20 and the carriage.

Of course, in other embodiments, the detachable connection between the charging cabinet 20 and the carriage is not limited to the threaded connection, such as plugging, buckling, splicing, etc., and is not specifically limited herein according to the actual situation.

When the accommodation space of the vehicle compartment is limited, particularly, the accommodation space in the up-down direction is limited, the charging cabinet 20 and the battery cabinet 10 may be placed in the vehicle compartment, respectively, for performing the related work, as shown in fig. 4. At this time, the charging housing 22 and the second battery housing 15 are detachably connected to the vehicle compartment through holes provided in the fixing plate, respectively.

Therefore, by separately providing the charging cabinet 20 and the battery cabinet 10, the overall height of the energy storage power supply 100 is reduced, and the height dimension of the compartment for accommodating the energy storage power supply 100 is also more contained.

In the present embodiment, the first input/output interface 16 is connected to the battery pack 14 through the cable 17, and the cable 17 can be bent and has a certain length, so that the distance between the charging cabinet 20 and the battery cabinet 10 can be changed, and the charging cabinet 20 and the battery cabinet 10 can be more flexibly arranged on the vehicle cabin.

When the accommodation space of the compartment is sufficient, particularly, the accommodation space in the up-down direction is sufficient, the charging cabinet 20 and the battery cabinet 10 are stackable and combined into a single structure in the up-down direction through the connection assembly, as shown in fig. 1.

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

Of course, a fixing plate may be disposed at the upper edge of the second battery case 15, and the fixing plate is provided with a threaded hole, and the threaded locking member is screwed into the threaded hole after passing through the through hole disposed on the charging case 22, thereby realizing the detachable connection of the charging cabinet 20 and the battery cabinet 10.

In other embodiments, the connection assembly may include a first connection element provided on one of the charging cabinet 20 and the battery cabinet 10, and a second connection element movably provided on the other of the charging cabinet 20 and the battery cabinet 10; when the connecting position is reached, the first connecting element and the second connecting element are mutually clamped.

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

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 of the battery cabinet 10 is approximately equal to the width dimension of the charging cabinet 20, specifically: the ratio of the length dimension of the battery cabinet 10 to the length dimension of the charging cabinet 20 is between 0.9 and 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 and 1.2; thus, when the battery cabinet 10 and the charging cabinet 20 are stacked in the up-down direction, 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 cell may be further increased to 7kw, h, or even more; then, it is conceivable that the size of the battery cells will correspondingly increase, and further, the size of the battery cabinet 10 will also increase. In order to ensure the consistency or coordination of the whole of the battery cabinet 10 and the charging cabinet 20 when they are stacked in the up-down direction, the length of the battery cabinet 10 is kept substantially consistent with the length of the charging cabinet 20, and the width of the battery cabinet 10 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 and 2.

Therefore, the charging cabinet 20 and the battery cabinet 10 are configured in a vertically stacked manner, so that the occupied area of the energy storage power supply 100 is smaller and more compact.

In the present embodiment, when the charging cabinet 20 and the battery cabinet 10 are placed in a stacked manner, the battery cabinet 10 is generally placed below. This is because: the battery compartment 10 has a greater weight and a smaller volume than the charging compartment 20, i.e., the battery compartment 10 has a greater density; the configuration of the charging cabinet 20 is supported by the battery cabinet 10, so that the stability of the whole of the energy storage power supply 100 is higher.

Further, the opening 154 is provided at the top of the battery case 12, and the second input/output interface 18 is provided at the right portion 224 of the charging case 22 on the same side as the opening 154, so that when the first input/output interface 16 is connected with the second input/output interface 18, the first input/output interface 16 and the cable 17 are relatively concentrated at the peripheral area of the second input/output interface 18, whereby the first input/output interface 16, the cable 17 and the second input/output interface 18 can be shielded by the gate member 229 provided on the charging case 22, forming the structure as shown in fig. 1; in this way, the whole energy storage power supply 100 is more concise, and dust, rainwater and the like are prevented from entering the input interface, so that the service life of the device is prevented from being influenced.

In the present embodiment, when the battery cabinet 10 and the charging cabinet 20 are stacked in the up-down direction, the battery cabinet 10 is located below and the charging cabinet 20 is located above; while the second input/output interface 18 is provided on the charging cabinet 20, the first input/output interface 16 is provided on the battery cabinet 10 through the cable 17, and the height of the charging cabinet 20 is greater than the height of the battery cabinet 10. In this way, when the first input/output interface 16 is connected to the second input/output interface 18, the operation space for the user is larger, and the operation is more convenient.

In the present embodiment, the extending direction of the rails of the battery pack mounting seat and the up-down stacking direction of the battery cabinet 10 and the charging cabinet 20 are parallel; in this way, in the process of using the energy storage power supply 100, the operation space considered for the insertion and extraction of the external battery pack coincides with the operation space in which the battery cabinet 10 and the charging cabinet 20 are placed in a stacked manner one above the other, and thus the use space of the energy storage power supply 100 is smaller and the space utilization rate of the compartment is higher.

Before using the stored energy power source 100, the user must first make a mechanical 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-down direction, so that the through hole provided on the charging cabinet 20 is aligned with the threaded hole on the battery cabinet 10; then, the threaded locking piece is screwed into the threaded hole on the battery cabinet 10 through the through hole, so that the mechanical connection between the battery cabinet 10 and the charging cabinet 20 is realized; finally, the first input/output interface 16 is plugged into the second input/output interface 18, so that an electrical connection between the charging cabinet 20 and the battery cabinet 10 is achieved.

In order to ensure neutrality of the through hole and the threaded hole and rapidity of stacking up and down, a first matching part can be designed on the top surface of the battery cabinet 10, and a second matching part can be designed on the bottom surface of the charging cabinet 20; when stacking up and down, the first matching part and the second matching part are matched with each other, namely, the alignment of the through hole and the threaded hole is realized.

In this embodiment, the weight of both the battery cabinet 10 and the charging cabinet 20 is greater than 50KG, and the electric energy transmitted between them has a relatively high voltage and/or current; if the mechanical connection and the electrical connection are realized by one step, it is difficult to consider both the safety and the connection strength. Therefore, the energy storage power supply provided by the application has the advantages that at least two actions are required by a user to realize the mechanical connection and the electrical connection of the charging cabinet 20 and the battery cabinet 10, so that the connection strength between the charging cabinet 20 and the battery cabinet 10 can be ensured while the safety is improved.

It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the application, which are all within the scope of the application.

The foregoing examples illustrate only a few embodiments of the invention and are described in detail herein without thereby limiting the scope of the invention. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the invention, which are all within the scope of the invention.
