It should be noted that, the illustrations provided in the present embodiment merely illustrate the basic concepts of the application by way of illustration, and only the components related to the application are shown in the drawings, rather than being drawn according to the number, shape and size of the components in actual implementation, and the form, number and proportion of the components in actual implementation may be arbitrarily changed, and the layout of the components may be more complex.

The garden electric tool is equipped with and driven by a battery pack, and the existing garden electric tool has the following problems in the using process: the problem of garden electric tools storage is that the existing garden electric tools are often directly placed in a home, and are inconvenient to carry when going out to a slightly far operation area for operation; the problem that gardens electric tool charged, current gardens electric tool appears the electric power deficiency in the operation in-process, then needs to return to home to charge, especially relates to a plurality of electric tools and carries out the operation simultaneously and need when supplementing electric power, extremely inconvenient. Based on this, the embodiment of the present application provides an energy station system as shown in fig. 1.

As shown in fig. 1, the energy station system includes an input energy source, a PCS module 110, an EVCC module 120, an AC output module 150, a DC output module 140, and a display module 130.

As shown in fig. 1, the input energy source may include an external charging post, a photovoltaic module 170, and a backup power source 160. Wherein the external charging post may comprise a DC charging post 202 and/or an AC charging post 201. The photovoltaic module 170 is a new energy module, which is a power generation device that generates direct current when exposed to sunlight, and is composed of a thin solid photovoltaic cell made almost entirely of a semiconductor material (e.g., silicon). The backup power source 160 may be, for example, a Storage battery (Storage battery), where the voltage of the backup power source 160 is 12V-1KV and the power is 1KW-100KW, and the backup power source 160 is used as a supplementary power source when other input power sources are insufficient to meet the load power demand, and the backup power source 160 may be used as an input power source or may be charged as a dc load of the energy station system.

As shown in fig. 1, PCS module 110: the brain of the whole energy station system is responsible for data processing and control of the whole energy station system; the power demand of the electric load is obtained through communication, and the available energy is distributed to the electric load, wherein the electric load comprises an external battery pack in a charging cabinet 300, a ZTR or electric vehicle, a backup power supply 160 and other direct current loads, and also can comprise an air conditioner, a kettle and other alternating current loads.

As shown in fig. 1, the EVCC module 120: and the system is responsible for state detection, internal relay control and power information transmission of the external charging pile. The method mainly comprises the steps of detecting the access condition of the charging pile, and controlling the corresponding internal alternating current or direct current relay according to the voltage difference between the output of the charging pile and the direct current or alternating current bus, wherein the voltage difference can be calculated through communication between the charging pile and the PCS module 110, and can be calculated through AD sampling. The power information transmission refers to that the EVCC module 120 obtains the power requirement of the load from the PCS module 110 and sends the power requirement to the charging pile, and meanwhile, the EVCC module 120 may obtain the available electric quantity from the charging pile, that is, the available output power of the charging pile, and send the available electric quantity to the PCS module 110 for further energy management.

As shown in fig. 1, AC output module 150: including an AC outlet that can output a charging current of at least one specification, which may be, for example, 1A-63a, the AC outlet being operable to power an AC load connected thereto. The DC charging pile 202, the photovoltaic module 170, or the backup power supply 160 may convert DC to AC through a DC/AC module (also referred to as a DC/AC bi-directional inverter) in the PCS module 110, and supply power to an AC load through an AC socket connected to the EVCC module 120; while the power of the AC charging stake 201 can be supplied directly to the AC load through the AC receptacle connected to the EVCC module 120.

As shown in fig. 1, the DC output module 140: comprising a first DC output module for powering at least one charging cabinet 300 (for charging a removable battery pack, which may be a battery pack of a different model) and a second DC output module for powering at least one gardening tool ZTR or an electric vehicle; the DC output module 140 includes at least one DC/DC charging module (for taking power from a DC Bus) and at least one PDU module 143 (corresponding to a power distribution outlet). When the second DC output module 140 is used to charge the electric vehicle, if the charging interface of the electric vehicle is different from the charging interface of the gardening tool ZTR, two types of charging guns need to be configured; if the charging interface of the electric vehicle is the same as that of the ZTR, only one charging gun may be configured, and the output voltage of the charging gun may be between 50 and 600V, for example. The power of the AC charging pile 201 may be converted from AC to DC by a DC/AC module (also referred to as a DC/AC bi-directional inverter) in the PCS module 110, and may power a DC load by the DC output module 140.

Generally, the power requirement of the battery pack in the charging cabinet 300 is smaller, so the DC/DC charging module in the first DC output module 140 may be a single DC/DC module 141, and of course, a DC/DC multiple-combination module of multiple DC/DC modules with smaller power may also be used; the gardening tool ZTR or the electric vehicle has a larger power requirement, so the DC/DC charging module in the second DC output module 140 may be a DC/DC multi-combination module 142 of a plurality of DC/DC modules; in addition, the DC/DC charging module in the second DC output module 140 may be a single high-power DC/DC module.

When the electric vehicle and the gardening tool ZTR share one charging gun for charging, the accessed load type is required to be acquired through a communication terminal on the charging gun, and when the accessed electric vehicle is detected, the power requirement corresponding to the electric vehicle is sent upwards so as to realize the power which is matched with the electric vehicle requirement finally; when the gardening tool ZTR is detected to be connected, the power requirement corresponding to the gardening tool ZTR is sent upwards, so that the power which is matched with the power requirement of the gardening tool ZTR finally is achieved.

Display module 130: the power utilization load monitoring system is used for monitoring the power utilization load conditions in the energy station and outside the energy station, so that the background management of a manager is facilitated; the system is also used for displaying the condition of the power consumption load, the load in the energy station can upload data in a wired or wireless mode, the load outside the energy station can upload data in a wireless mode, the uploaded data is processed by the PCS module 110 and displayed by a display device in or outside the vehicle through the PCS module, and a manager or an operator can acquire the condition of the related load conveniently.

Fig. 2 illustrates an energy distribution method applied to the above-described energy station in an exemplary embodiment of the present application. Referring to fig. 2, the energy allocation method of the energy station includes:

step S210: receiving a power demand uploaded by a load connected to an output module;

step S220: acquiring a total power demand according to the received power demand uploaded by the load;

step S230: obtaining the outputtable power of a plurality of input energy sources;

step S240: performing energy allocation management based on the total power demand, the outputtable power of the plurality of input energy sources and the power supply priority of each input energy source;

step S250: and controlling an output module to supply power to each access load based on the energy distribution result.

FIG. 3 illustrates a control logic diagram of energy allocation for an energy station of the present application; FIG. 4 illustrates a control logic diagram of energy allocation of energy stations in consideration of charging priority in the present application; the energy distribution scheme of the energy station of the present application will be described in detail with reference to fig. 1 to 4.

First, step S210 is performed: the power requirements of the load upload to the output module are received.

As shown in fig. 3-4, at the beginning of energy distribution, a load status detection is required to detect whether a load is connected to the output module, and when the load is connected to the output module (AC output module 150 and/or DC output module 140), its power requirement is uploaded to the PCS module 110. The loads include a dc load and an ac load, the dc load may include one or more of a combination of a backup power source 160, a garden tool, an external battery pack in the charging cabinet 300, and an electric vehicle.

The manner in which the load uploads the power demand varies according to the type of load, and will be described in detail below:

when a battery pack is inserted into the charging cabinet 300, the power requirements of the battery pack in the charging cabinet 300 are uploaded to the PDU module 143, and the PDU module 143 uploads the power requirements to the PCS module 110.

When the gardening tool ZTR or the electric vehicle is connected, the power demand thereof is uploaded to the PCS module 110 through the CAN bus via the charging gun.

There are two cases of AC loads, an AC load having no communication function and a communication function. When the alternating current load does not have a communication function, only the power requirement of the direct current load is uploaded through a CAN bus or a wireless communication mode; when the ac load is provided with a communication function (wireless communication), it may establish a connection with the PCS module 110 through the wireless communication manner and upload a power demand, and the final power demand is the sum of the ac load and the dc load power demand.

Next, step S220 is performed: and acquiring the total power demand according to the received power demand uploaded by the load.

After the PCS module 110 receives the power requirements uploaded by the load, it needs to aggregate the power requirements to obtain the total power requirement for subsequent energy allocation management.

Because some or all of the ac loads do not have communication functions, the power requirements cannot be uploaded, so that the PCS module 110 may have smaller power requirements than actually required when performing power aggregation, but when power is supplied, the power needs to be distributed to the ac loads first, which may cause insufficient other loads.

Therefore, in a specific embodiment, when the total power demand is obtained according to the received power demand uploaded by the load, the received power demand uploaded by the load can be summarized first, and then a preset additional power demand is added on the basis of the summarized power demand to serve as the total power demand, wherein the preset additional power demand is used for replacing the power demand of the load incapable of uploading the power demand, so that the situations of unequal external input energy and actually required power demand are reduced in a certain proportion. In this embodiment, the external input energy source includes a photovoltaic module 170 and/or a charging post. When total power demands are summarized, the power demands of loads incapable of uploading the power demands are fully considered, so that energy distribution can be achieved more efficiently and accurately.

In another embodiment, the power requirements of the ac load that cannot upload the power requirements can be obtained by providing a current sensor or an ammeter in the ac load loop, and then the power requirements uploaded by the received load are summarized to obtain the total power requirement. When total power demands are summarized, the power demands of loads incapable of uploading the power demands are fully considered, so that energy distribution can be achieved more efficiently and accurately.

In another embodiment, when the total power demand is obtained according to the received power demand uploaded by the load, the power demand of the ac load which cannot upload the power demand is not considered, but when the output module is controlled to supply power to each access load based on the energy distribution result (i.e. step S250), when the actually required power demand is greater than the outputtable power of the external input energy source, the backup power source 160 supplements the power demand, so that the situations that the external input energy source and the actually required power demand are unequal are reduced in a certain proportion. Since the backup power supply 160 is directly connected to the dc bus, the backup power supply 160 can adjust the charge and discharge modes according to the voltage difference between itself and the dc bus. When the voltage of the backup power supply 160 > the voltage of the direct current bus, the backup power supply 160 discharges; when the voltage of the backup power supply 160 is less than the voltage of the dc bus, the backup power supply 160 is in a charged state, that is, the switching of the charge and discharge modes is automatically implemented according to the voltage difference.

Next, step S230 is performed: the outputtable power of a plurality of input energy sources is obtained. The PCS module 110 may communicatively obtain the outputtable power of the input energy to the access energy station system. The input energy sources include a photovoltaic module 170, a backup power source 160, and a charging stake (AC charging stake 201 and/or DC charging stake 202).

Next, step 240 is performed: and performing energy distribution management based on the total power demand, the outputtable power of the plurality of input energy sources and the power supply priority of each input energy source. Because the energy station system can be connected with a plurality of input energy sources at the same time, when the energy sources are distributed and managed, in order to reasonably utilize the input energy sources to charge the input load with high efficiency, the charging requirement of a user is met, and the power supply priority of the input energy sources needs to be considered.

When multiple input energy sources are accessed, loads in the energy station may be powered according to a default power priority of the input energy sources. The input energy with the highest priority is preferentially adopted for power supply, and when the output power of the input energy with the highest priority cannot meet the power requirement of the current access load, one or more other input energy sources are additionally selected for power supply according to the power supply priority order.

As an example, the default power supply priority of the system may be that the photovoltaic module > DC charging pile > AC charging pile > backup power, and if the output power of the photovoltaic module 170 can meet the power requirement of the current access load, the photovoltaic module 170 (the photovoltaic module 170 is always accessed and is only affected by solar illumination and subsequent priority switching) may supply power; if the photovoltaic module 170 is not satisfied, it is complemented by other incoming input energy DC charging piles 202 and/or AC charging piles 201 and/or backup power sources 160 sources.

When a plurality of input energy sources are connected, the power supply priority of each input energy source can be adjusted according to the input instruction of the user at the mobile terminal or the cloud, and the power supply priority of the input energy sources can be automatically adjusted according to the preset rule in the system.

In a specific embodiment, the power supply priority of the input energy source can be automatically adjusted according to the access condition of the charging pile, and when the charging pile is accessed, the priority of the charging pile is adjusted to be the highest. As an example, when a DC charging pile 202 and/or an AC charging pile 201 is accessed, the default power supply priority is switched to DC charging pile and/or AC charging pile > photovoltaic module > backup power.

In another embodiment, the power priority of the charging stake is automatically adjusted based on the period of power utilization Gao Fenggu. As an example, during peak electricity usage periods, the default power supply priority is maintained, while during valley electricity usage periods, the default power supply priority is switched to DC charging piles and/or AC charging piles > photovoltaic modules > backup power.

In yet another embodiment, the power supply priority of each input energy source is automatically adjusted according to the output power of the photovoltaic module 170, and the factors affecting the output power of the photovoltaic module 170 may be the time period and weather conditions. In practical application, the comparison between the output power of the photovoltaic module 170 and the preset power threshold may be performed, when the output power of the photovoltaic module 170 is smaller than the preset power threshold, the adjustment of the power supply priority is performed, and when the output power of the photovoltaic module 170 is smaller than the preset power threshold, the default power supply priority may be maintained.

As an example, the output power of the photovoltaic module 170 may be affected by the time period on the one hand. In the morning and evening, the weak illumination may cause the output power of the photovoltaic module 170 to be less than the preset power threshold, so that priority switching is required; in addition, at night without illumination, the output power of the photovoltaic module 170 is zero, which also requires priority switching; that is, when the DC charging pile 202 and/or the AC charging pile 201 are/is connected, the default power supply priority is switched to the DC charging pile and/or the AC charging pile > the photovoltaic module > the backup power supply in a period of weak sunlight or no sunlight when the output power of the photovoltaic module 170 is smaller than the preset power threshold.

As an example, the output power of the photovoltaic module 170, on the other hand, may also be affected by weather conditions. For example, in a period other than the morning, evening, and night, the weather conditions in the outdoor operation area may be affected, that is, the generation of a cloudy day or a rainy day may cause the output power of the photovoltaic module 170 to be less than the preset power threshold, so that priority switching is required. That is, when the DC charging pile 202 and/or the AC charging pile 201 are/is connected, the default power supply priority is switched to the DC charging pile and/or the AC charging pile > the photovoltaic module > the backup power supply on a cloudy day or a rainy day when the output power of the photovoltaic module 170 is smaller than the preset power threshold, and the default power supply priority is adopted on a sunny day when the output power of the photovoltaic module 170 is larger than the preset power threshold.

The power supply priority of each input energy source can be adjusted in various modes, so that different input energy sources can be reasonably utilized to supply power for the access load, and the charging efficiency is improved.

In the above embodiment, a time threshold may be further set in the process of switching the priority, and switching is performed only when the set time threshold is satisfied, so as to avoid frequent switching caused by immediately responding to switching when detecting that the time threshold is smaller than the preset power threshold, thereby improving the stability of the system;

in the above embodiment, the average value of the output power in the preset time period may be calculated and compared with the preset power threshold, and when the average value of the output power of the photovoltaic module 170 in the preset time period is smaller than the preset power threshold, the switching is performed, so that the system stability may be further enhanced.

Finally, step 250 is performed: and controlling an output module to supply power to each access load based on the energy distribution result.

After the PCS module 110 performs energy distribution management based on the total power demand, the outputtable power of the multiple input energy sources, and the power supply priority of each input energy source, the PCS module may control the AC output module 150 to supply power to the accessed AC load and/or control the DC output module 140 to supply power to the accessed DC load according to the input energy source power supply priority order based on the energy distribution result until the accessed load is full, and then end the charging process.

When the actually required power demand is greater than the outputtable power of the external input energy source, the backup power source 160 can be used for supplementing the power demand, so that the situations that the external input energy source and the actually required power demand are unequal are reduced in a certain proportion.

In the process of supplying power to the load, new load access is possible at any time, so in the process of supplying power to the load, whether a new load access output module exists or not needs to be detected, when the new load access output module is detected, the step of receiving the power requirement uploaded by the load is returned, namely, in the step S210, and the steps S210-S250 are re-executed.

As shown in fig. 3 and 4, when the access load has a charging priority, then in performing energy allocation management, energy allocation management needs to be performed based on the total power demand, the outputtable power of the multiple input energy sources, and the charging priority of the load; and then controlling the output module to supply power to each access load according to the charging priority of the load based on the energy distribution result, thereby reasonably utilizing input energy, providing diversified charging services and meeting different power consumption requirements. Of course, in order to reasonably utilize multiple input energy sources to efficiently charge an access load, when performing energy allocation management, it is necessary to consider the power supply priority of each input energy source, that is, perform energy allocation management based on the total power demand, the outputtable power of multiple input energy sources, the power supply priority of each input energy source, and the charging priority of the load.

As shown in fig. 4, in order to realize diversified charging demands, the charging priority setting of the access load is adjustable. When the charging priority of the access load is adjustable, before energy allocation management is performed, whether the charging priority is adjusted or not (also called updating) needs to be checked; when the charging priority is not adjusted, the PCS module performs energy distribution management based on the total power demand required by the load, the outputtable power of a plurality of input energy sources and the default charging priority, and then supplies power to each access load according to the default charging priority; when the charging priority is adjusted, the PCS module performs energy distribution management based on the total power demand required by the load, the outputtable power of a plurality of input energy sources and the updated charging priority, and then supplies power to each access load according to the updated charging priority.

As can be seen from the above, the energy distribution method of the energy station of the present embodiment receives the power requirement uploaded by the load connected to the output module; acquiring a total power demand according to the received power demand uploaded by the load; obtaining the outputtable power of a plurality of input energy sources; performing energy allocation management based on the total power demand, the outputtable power of the plurality of input energy sources and the power supply priority of each input energy source; and controlling the output module to supply power to each access load based on the energy distribution result. When the energy distribution is carried out, the total power requirement of the access load, the output power of a plurality of input energy sources and the power supply priority of each input energy source are considered, so that the input energy sources can be reasonably utilized to carry out high-efficiency charging on the access load, and the charging requirement of a user is met.

It should be noted that, the above steps of the methods are divided, for clarity of description, and may be combined into one step or split into multiple steps when implemented, so long as they contain the same logic relationship, and they are all within the protection scope of the present patent; it is within the scope of this patent to add insignificant modifications to the algorithm or flow or introduce insignificant designs, but not to alter the core design of its algorithm and flow.
