Description

Electric vehicle charging management system, device with electric vehicle management function and electric Vehicle charging management method

The invention relates to an electric vehicle charging device, in particular to an electric vehicle charging management system, a device with electric vehicle management functions and an electric vehicle charging management method.

Due to the advantages of environmental protection, low noise, easy maintenance and maintenance, and low cost of use, electric vehicles have become the mainstream of the current automotive industry. However, the current market share of electric vehicles only accounts for 2.6% of global car sales (2019). Of course, with the promotion of policies in various countries, the market share of electric vehicles will gradually increase.

With the gradual development of electric vehicles, the demand for charging stations has also increased. At present, mainstream commercial charging stations all provide fast charging functions. At present, there are commercial manufacturers that can provide 900kW (kilowatt) ultra-high power fast charging technology (current can reach 360A ampere), so that electric vehicles can be charged within 5 minutes. It can be charged to the extent that it can travel 400 kilometers. However, such fast charging technologies will cause a huge load on the power system.

According to our country's policy, those with a contracted capacity exceeding 800kW are defined as large electricity consumers. The total power consumption of large power consumers exceeding 800kW is more than 50% of the total power consumption in Taiwan. high capacity electricity As a rare resource, any area that wants to re-establish power needs needs to be evaluated by Taiwan Power Company to confirm whether there is enough power and the corresponding feeders can provide it. Therefore, although there is a demand for widespread fast-charging charging stations, it is necessary to consider whether the overall power supply system is sufficient to cope.

For general collective housing, its future problems are more obvious. For example, when there are 100 households in a high-rise building, and all of them are electric vehicles, if all of them are equipped with IEC 62196-2 Type 2, 3-phase 400V (volt)/12.8kW charging heads, 100 households will need 1,280kW power configuration. This building immediately became a major electricity consumer. If the number of households in another building is 300, the electricity demand increases to 3,840kW. For another example, if all Tesla super chargers (480V/140kW) are used, the power demand of 100 households will be 14,000kW, and the power demand of 300 households will be 52,000kW, which is far beyond that of many large industrial households. electricity demand. In terms of my country's limited power infrastructure, it is completely unable to cope with this huge charging demand.

However, the current charging stations are all based on a single charging demand for electric vehicles, and do not take into account the huge charging demand of these collective residences. In order to solve this problem, CN102655335A Patent Publication adopts the technology of parallel management of community monitoring stations, and controls the quality of service through user selection, so that the limited power supply can limit the actual output through the parallel method . However, this technology can only select the quality of service on each charging station, that is, each charging station is not a charging station exclusive to a certain user, and the selection is a single selection. The community monitoring station can perform column control (that is, charging schedule) based on all currently selected users, which is not fully applicable to collective housing.

In addition, for the users of collective houses, each user has different habits of using vehicles. For example, some people drive out for many days, but they are always plugged in the charger; Go out at 10 o'clock, come back at 10 o'clock in the evening, and only drive 10 o'clock every day kilometer. All kinds of different habits of using charging stations have not been adopted at present, and are incorporated into the electric vehicle charging management system of collective houses. In addition, the prior art does not provide a charging management system for collective housing with a mobile device to perform the above-mentioned personal habit setting mode, so as to make the charging management system of collective housing more intelligent.

Therefore, how to plan ahead and design an electric vehicle charging management system for collective housing, so that it can accept the users in the collective housing to make personal use settings through the application program of the mobile device, and, further, the system collects The user's electric vehicle usage habits are statistically calculated to obtain the optimal charging management schedule, and, furthermore, the system can temporarily share the charging station of the parking space with other friends' electric vehicles through the application program of the mobile device. It has become an important direction for the development of electric vehicle charging management system technology for future collective residences.

FIG. 4A and FIG. 4B are schematic diagrams of the status screens of the terminal machine 70 connected to the controller 20 monitoring the status of the fully distributed charging management system in one embodiment of the present invention.

FIG. 5A to FIG. 5I illustrate a specific embodiment of the present invention, illustrating how users can realize personalized charging settings through a fully distributed charging management application program on a mobile device.

The present invention uses a fully distributed charging management application program (APP) on a mobile device and a battery The controller (or server) of the electric vehicle charging management system sets the personalized charging requirements, and then analyzes the statistical data of the user's electric vehicle charging behavior through the controller (or server) to generate an optimal electric vehicle charging Setting suggestions can be implemented to optimize the setting of personalized charging needs, and meet the limited power of collective housing, and the special technical functions of personalized and optimized charging management needs.

Please refer to Figure 1, which is the overall system architecture diagram of the fully distributed electric vehicle charging management system of the present invention, which includes: a master meter 60, a controller 20, a circuit breaker 30-1, a circuit breaker 30-2, and a circuit breaker 30 -3, circuit breaker 30-n, electric meter 40-1, electric meter 40-2, electric meter 40-3, electric meter 40-n, charging pile 50-1, charging pile 50-2, charging pile 50-3, charging pile 50 -n, charging head 53-1, charging head 53-2, charging head 53-3, charging head 53-n; charging head 53-1, charging head 53-n can be used for electric vehicle 80-1, electric vehicle 80- n charging, its specifications will correspond to the brands of electric vehicle 80-1 and electric vehicle 80-n. The charging pile 50-1, the charging pile 50-2, the charging pile 50-3, and the charging pile 50-n each have a screen 51-1, a screen 51-2, a screen 51-3, a screen 51-n and a start button 52-1 , start key 52-2, start key 52-3, start key 52-n. Generally speaking, charging piles and charging heads are equipment provided by the electric vehicle site. Therefore, in terms of system architecture, the current more suitable way is to connect the total electric meter 60 to the electric meter 40-1, electric meter 40-2, and electric meter 40-3. 1. After the hardware system of the electric meter 40-n is built, the user is allowed to install the charging pile and the charging head by himself.

It can be seen from the system architecture in Figure 1 that when the number of n is large enough, there will be a technical problem that the overall power demand is too large. The controller 20 limits the charging pile 50-1, charging pile 50-2, charging pile 50-3, charging The amount of current and the power supplied by the pile 50-n, that is, through the overall deployment of the power of the charging pile 50-1, the charging pile 50-2, the charging pile 50-3, and the charging pile 50-n, to realize the overall consumption Power Control.

Basically, for general electric vehicles, especially for urban users, since commuters are the main purpose of use, the daily power consumption of electric vehicles is about 10%. In other words, Electric vehicles can be fully charged once in about 10 days. This can be used as a reference for the overall power consumption of the fully distributed electric vehicle charging management system of the present invention. While nighttime is the main charging time, electric vehicle owners may also charge outside during the day. Therefore, 10% to 15% of the overall electric vehicle power demand can be used as the overall power demand plan. Taking a 60kwh (kilowatt-hour) electric vehicle as an example, if it takes about 50kwh~55kwh to fully charge (according to consumer behavior, generally electric vehicles will not be charged until the power is completely exhausted), then 6kw can be charged. Charge for about 9 hours to plan. In other words, if 300 households implement the fully distributed electric vehicle charging system, with a utilization rate of 15%, the power demand is 300x0.15x6=270kw. Compared with the aforementioned IEC 62196-2 Type 2, 3-phase 400V (volt)/12.8kW charging head, 300 households need a power configuration of 3,840kW, which is greatly reduced.

Taking the contracted capacity of the 270kw charging system as an example, when a user has a demand for fast charging, the charging power can be appropriately increased depending on the power margin of the existing system, and the concept of "variable fast charging" can be implemented. Taking the aforementioned embodiment of 300 charging piles as an example, if there are currently 30 electric vehicles charging according to the general 6kw standard mode, 180kw of power is used, and there is still 90kw of capacity available for use. If there are two fast charging needs at this time, each can be configured with a power of 45kw, so that it can complete its 60kwh battery charge within 1 hour and 20 minutes. If there are 40 electric vehicles currently charged according to the general 6kw standard mode, then 240kw of power is used, and there is still 30kw of capacity available for use. If there are two fast charging needs at this time, each can be configured with a power of 15kw, so that it can complete its 60kwh battery charge within 4 hours. So on and so forth.

With such technical means of overall deployment and variable fast charging, the overall power consumption of the fully distributed electric vehicle charging system of the present invention can be controlled within the scope of the contracted capacity without causing a load on the overall power system .

Therefore, a main technical feature of the present invention is how to use the controller 20 to The dynamic control of the circuit breaker 30-1, the circuit breaker 30-2, the circuit breaker 30-3, and the circuit breaker 30-n realizes the aforementioned power distribution in various states. In addition, another main technical feature of the present invention is how to analyze the user's electric vehicle charging behavior and set the user's own personal needs through the mobile device 10 to achieve optimal power allocation. Below, they will be explained separately.

Please refer to FIG. 2A and FIG. 2B , which are the hardware configuration diagram of the mobile device 10 and the hardware configuration diagram of the controller 20 respectively.

Among them, the mobile device 10 in Figure 2A includes: one or more processors 11, memory 12, communication unit 13, screen 15, etc. Most of the current mobile devices are smart mobile devices, and most of the screens are touch-sensitive devices. monitor. In the memory 12, a full-distributed charging management application program 14 has been installed therein. One or more processors 11 are used to execute the fully distributed charging management application program 14, and control the communication unit 13, the memory 12 to send and receive data, access and other operations. The communication unit 13 can communicate with the external Internet (not shown) and communicate with the controller 20 (FIG. 2B). The controller 20 in FIG. 2B includes: a processor 21 , a memory 22 , a communication unit 23 and so on. The controller 21 is used to control the operation of the communication unit 23 and the memory 22, and control the circuit breaker 30-1, circuit breaker 30-2, circuit breaker 30-3, circuit breaker 30-n to charge the charging pile 50-1, The pile 50-2, the charging pile 50-3, and the charging pile 50-n perform current limiting or cut-off. Wherein the locomotive rear view device 20 utilizes the power source of the battery of the locomotive 100, or can provide its independent power source, and this is a part of the prior art, so it will not be repeated here. The communication unit 23 can adopt a WiFi module or a mobile communication module to communicate with the mobile device 10 through a local area network or a telecommunication network. The memory 22 can be an internal memory of the controller 21, or an independent memory, which is also a part of the known technology, and will not be repeated here.

Next, please refer to FIG. 3, the main flow chart of the control method of the fully distributed electric vehicle charging system of the present invention. In the following, the present invention will be described with reference to FIG. 4A, FIG. 4B, and FIG. 5A to FIG. 5I. How to achieve personalized charging parameter setting and charging system optimization with advanced technical means. Figure 3 contains the following steps:

Step S101: Confirm the number of electric vehicles that have entered the charging state. The charging pile 50-1, the charging pile 50-2, the charging pile 50-3, and the charging pile 50-n respectively have a start key 52-1, a start key 52-2, a start key 52-3, and a start key 52-n. The concept of entering the charging state in this step can be carried out in many ways. For example, when the charging head is inserted into the electric vehicle, the system is regarded as activated and enters the charging state. This is the basic action. The second situation is that after inserting the charging head into the electric vehicle and pressing the start button, the electric vehicle is considered to be in the charging state. After this step, the controller 20 can manage the charging of electric vehicles, that is, first count how many electric vehicles have entered the state of charging start, that is, the state of preparing to charge.

Step S102: confirming the plurality of personalized charging settings of the electric vehicles. Next, it is to judge the personalized charging setting status of each electric vehicle, and then schedule the charging.

Step S103: Carry out an optimal schedule based on the number of electric vehicles to be charged and the contents of the personalized charging settings, based on not exceeding the contracted power capacity, and dynamically according to the personalized charging settings Adjust the value of general charging power, a value of variable fast charging power, a value of extremely slow charging power, etc., and calculate a charging schedule for these electric vehicles.

Please refer to FIG. 4A and FIG. 4B , which are schematic diagrams of the terminal machine 70 connected with the controller 20 to monitor the status screen of the fully distributed charging management system. In the embodiment shown in FIG. 4A, the screen 71 displays an overall system status picture 73-1. The overall system status screen 73-1 includes a basic data column 73-2 and a status column 73-3. Taking the present embodiment in Fig. 4A as an example, the overall system status screen 73-1 displays basic data such as "rated power: 200kw", "number of charging piles: 150", "number of registrations: 130". Plus the data in the status column 73-3, that is, "charging power: 190kw"; "charging vehicle: 25", "To-be-scheduled quantity: 1", "Quick charge quantity: 1", "Normal charge quantity: 19", "Extremely slow charge quantity: 5", etc. These are based on the basis of step S101 and step S102, And adjust the result of the value of the general charging power in step S103. In this embodiment, specific data can also be displayed, for example, "general charging power: 6kw", "fast charging power: 66kw", "very slow charging power: 4kw"; or, "general charging power: 6kw" , "Fast charging power: 71kw", "Extremely slow charging power: 3kw". In the embodiment shown in FIG. 4A, there is an electric vehicle waiting to be scheduled, and the fast-charging electric vehicle can be fully charged before entering the schedule. The execution in Fig. 4A requires the user to perform the action of personalized charging setting in advance, and the actual result can refer to the embodiment in Fig. 4B.

In the embodiment shown in FIG. 4B, the screen 71 displays a parking space status management screen 72-1, which mainly includes a parking space status information column 72-2 and a pull-down menu 72-3. In the embodiment shown in FIG. 4B, the parking space status information column 72-2 includes information such as number, status, and personalized settings. And the drop-down menu 72-3 can display the detailed content of the personalized setting (not shown), which can be equivalent to the part of the embodiment in FIG. 5E to FIG. 5I. Wherein, in this embodiment, the personalized setting includes "finish" and "system setting". When the user sets and saves the set value, the system can follow the user's personalized setting; on the contrary, if the user does not set it by himself, the system can perform dynamic charging allocation according to the preset value.

Next, please refer to FIG. 5A to FIG. 5I , which specifically illustrate how the user implements personalized charging settings through the fully distributed charging management application 14 on the mobile device 10 . In FIG. 5A , the screen 15 of the mobile device 10 displays a battery status icon 15 - 1 , a charging information field 15 - 2 , a charging start button 15 - 3 and a schedule setting button 15 - 4 . The user can choose to press the start button on the charging pile, or click the start charging button 15 - 3 on the screen of the fully distributed charging management application 14 on the mobile device 10 to enter the charging schedule. This is the various implementation states of the activation key in step S101. When "charging is started", the full-distributed charging management application 14 displays the state shown in Figure 5B, enters the charging schedule, and The charging schedule symbol 15-5 is displayed. Once the scheduled time (such as 23:15 in Figure 5B) is up, the charging will start. As shown in Figure 5C, the charging information column 15-2 shows that the battery status has increased from 30% in Figure 5B to the first 50% of Figure 5C. When fully charged, the charging information column 15-2 shows that the battery status is 100%, and the battery status pattern 15-1 also changes accordingly.

From the embodiments shown in Figures 5A to 5D, it can be seen that the user can clearly grasp the charging status of the electric vehicle through the fully distributed charging management application 14, and more importantly, the fully distributed charging management application 14 can perform personal charging. For charging settings, please refer to Figure 5E to Figure 5I. When the user clicks the schedule setting button 15-4, the full-distributed charging management application 14 displays the schedule setting option screen shown in FIG. 5E, which includes multiple schedule setting options, such as the first schedule option 15 -41, the content is: the latest charging completion time; the second schedule option 15-42, the content is: use the fast charging quota; the third schedule option 15-43, the content is: allow the minimum charging amount; the fourth schedule Option 15-44, the content is: the system recommends using the mode. When the user clicks individual options, the screens shown in FIG. 5F to FIG. 5I will pop up respectively.

When the user presses the first scheduling option 15-41 in Figure 5E, the full-distributed charging management application 14 will correspondingly jump out of the screen in Figure 5F, and the detailed content of the first scheduling option 15-41 can be found in it. Allow the user to input the data of the latest charging completion time, and press the save button to store the set value. The parameter of the latest charging completion time is very important data for the fully distributed charging management program 24 . Because this data allows the full-distributed charging management program 24 to adjust the schedule of each electric vehicle, allowing its time to go forward or backward, so that the schedule is more flexible.

When the user presses the second scheduling option 15-42 in Figure 5E, the full-distributed charging management application 14 will correspondingly jump out of the screen in Figure 5G, and the detailed content of the second scheduling option 15-42 can be found in it. Let the user press the fast charging button. In the embodiment of FIG. 5G, since the user has already used the fast charging amount, the screen displays that the current fast charging amount is 0. Therefore, use the key to cut off (Disable) state, cannot be clicked.

When the user presses the third scheduling option 15-43 in Figure 5E, the full-distributed charging management application 14 will correspondingly jump out of the screen in Figure 5H, and the detailed content of the third scheduling option 15-43 can be found in it. Allow the user to input the data that allows the minimum charging capacity, and press the save button to store the set value. Taking the embodiment in FIG. 5H as an example, the minimum charge data input by the user is 60%, that is, the user agrees that the system can only be fully charged to 60%. This embodiment can be used when the system power is tight. In other words, when more users set this function, the fully distributed charging management program 24 can have more leeway to meet the charging needs of more users. And this embodiment can be used with the public electricity fee payment mechanism of the collective residence, in other words, let the user who agrees to the minimum charging amount get a subsidy when this situation actually occurs, so as to reduce the sharing ratio of the electricity fee, and the source of this subsidy is fast charging User's increase sharing ratio.

When the user presses the fourth scheduling option 15-44 in Figure 5E, the full-distributed charging management application 14 will correspondingly jump out of the screen in Figure 5I, and the detailed content of the fourth scheduling option 15-44 is displayed inside. After the statistics of the full-distributed charging management program 24, the suggested charging mode for the user can be stored and executed after the user presses the adopt button. Taking the example in Figure 5I as an example, the results of system analysis show that the user has never used fast charging, so a suggestion is made to exchange the fast charging quota with others, and it is recommended to charge 5% according to the schedule every day, and the maximum charging capacity is 80 %Wait. This system suggests that it can also be combined with the aforementioned subsidy scheme to allow other users who need it to perform fast charging.

In terms of another embodiment of the present invention, it is also possible to add a fast charge exchange option on the fast charge quota screen in Figure 5G, so that the fast charge quota can be transferred to other users, and the share ratio of your own electricity consumption can be reduced. to reduce costs.

According to another embodiment of the present invention, a setting option for charging pile sharing can also be added in FIG. 5E , that is, a fifth scheduling option. When the user selects this option, they can enter the information they want to share The relevant information of the electric vehicle, so that after the all-distributed charging management program 24 records the relevant information of the shared electric vehicle, when the electric vehicle enters the schedule, dynamic charging adjustment is performed. This sharing mechanism can be connected in series with other electric vehicle charging sharing platforms, further improving the practicability of the present invention.

It can be known from the above embodiments and related descriptions of the schedule setting in FIG. 5E to FIG. 5I that, through the various schedule settings of the fully distributed charging management application program 14, the fully distributed charging management program 24 can control different electric vehicles. Based on the user's habit of using electric vehicles, the parameters of these personalized charging settings are used to implement better scheduling settings. Let the fully-distributed charging management program 24 have greater possibilities and greater flexibility, which can meet the contract capacity and serve the fully-distributed electric vehicle system of collective housing that far exceeds the theoretical power demand. Therefore, through the technical means of the present invention, it is possible to achieve special technical effects such as personalized charging setting, minimization of power demand for collective housing, and dynamic charging management.

Although the technical content of the present invention has been disclosed above with preferred embodiments, it is not intended to limit the present invention. Any modification and modification made by those skilled in the art without departing from the spirit of the present invention should be covered by the present invention. Therefore, the scope of protection of the present invention should be defined by the scope of the appended patent application.
