Description

Electric vehicle charging system and its providing method

The present invention relates to an electric vehicle charging system and a method of providing the same, and more particularly, to an electric vehicle charging system and a method of providing the same, which can be charged and parked at the same time as an electric vehicle, and supply residual power inside the electric vehicle to a central system. It is about.

In particular, according to the maximum charging completion time information and the desired price information of each electric vehicle, not only to use the surplus power as efficiently as possible by changing the charging time, but also to provide the economical effect to the user of the electric vehicle by the lowest charging amount An electric vehicle charging system and a method of providing the same.

Electric cars, powered by electricity, appeared in the late 1880's and were used for passenger cars, trucks, and buses. In the 1920s, the early days of the automotive industry, when limited mileage was not a big problem because of the relatively low speed and battery recharging, electric vehicles were particularly luxury cars used in the city, connecting freight to very close points. It was in competition with a petroleum fuel car, which is a carrier. However, as time went by, it was gradually starting to compete with petroleum-fueled cars due to battery recharge problems.

In recent years, interest in electric vehicles has increased in countries around the world to reduce carbon dioxide emissions caused by environmental pollution. In addition, by establishing an infrastructure such as installing a charging station for recharging the battery, much effort is being made to activate the electric vehicle.

While many cars are being supplied and operated around the world, 80% of all vehicles are always parked. Therefore, if the electric vehicle is charged with electricity, a very large amount of power remains unutilized inside the parked electric vehicle. If the surplus power is utilized in the high power usage time and can be recharged in the low power usage time, the efficiency of the power usage can be maximized.

Recently, Smart Grid has been spotlighted in this respect. Smart Grid means an intelligent power grid, and sensors installed in power companies' integrated control centers, power plants, transmission towers, electric poles, and home appliances exchange information in real time in both directions. It refers to a system that can efficiently produce and consume power. For example, refueling during the daytime, which has a high electric charge, can be controlled to run the washing machine at night, which is relatively low in cost, and an electric vehicle can be charged only at night time. In addition, electricity generated by photovoltaic power generation can be traded through exchanges. The smart grid system, one of the largest and fastest growing segments of the next-generation eco-friendly technology market, can save more than 10% of existing generation. Therefore, reducing power waste and making use of renewable energy more practical will help alleviate global warming.

Therefore, it can be provided to an integrated operating system that can simultaneously drive and park an electric vehicle.In such a system, when the electric power usage is high (high power unit price), the electric vehicle is charged with electricity and the power consumption is used. During this low time period, if electric vehicles can be charged, efficient power generation and consumption will be possible.

However, since such a system has not been developed to date, there is a problem that the amount of unused power remaining in the parked electric vehicle is considerably large. In particular, the amount of electricity remaining in electric vehicles is tens of times the daily electricity consumption of households. In addition, since electric vehicle charging is usually performed in an office dense area or a residential area at rush hour, there is a problem in that a peak of power usage occurs at the same time in this area, and thus, a power generation facility for this needs to be increased.

Therefore, the intelligent electric vehicle charging system and the method of providing the same according to the present invention have been devised to solve such a problem, 1) provides an integrated charge calculation function of parking and charging of the electric vehicle, and 2) according to the departure time of the electric vehicle user. Its purpose is to reduce the charging cost by scheduling the battery to be charged at the lowest possible price, and 3) to manage power efficiently by linking the power grid for peak management of power demand.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

As used herein, the electric vehicle is meant to include not only an electric vehicle but also all riding means that can be driven by electricity, such as an electric bicycle.

1 is a block diagram of an intelligent electric vehicle charging system according to the present invention. Intelligent electric vehicle charging system according to the present invention is composed of a power storage 50 for storing the power of the parking lot, and the charging management module (1) for planning and managing the charging schedule.

The charging management module 1 includes an input device 17 for inputting maximum charging completion time information of a parked electric vehicle and desired price information, a power management device 11 for managing power information of the power storage 50, and power A charging scheduler 12 that plans a vehicle charging schedule that can be met within the maximum charging completion time information and desired price information based on the power information of the management device, and a charging that determines the charging fee and the parking fee according to the vehicle charging schedule. A charging device 13 and a charging device 15 for charging the parked electric vehicle. According to an embodiment of the present invention, when there are a plurality of parked electric vehicles, a technical configuration of mutual power trading between electric vehicles through the charging system is provided along with which of the plurality of electric vehicles is to be preferentially charged.

The charging management module may be connected to an external power grid (particularly a smart grid) to perform efficient power management while transmitting and receiving power. 3 is a configuration diagram showing a relationship with such an external power grid. The external power grid is represented by an external power client 60. This may export the surplus power inside the system to the external power client 60, or may receive and utilize external power from the external power client 60. This power transmission and reception is performed by the power management device 11. The external power client 60 may be connected to the power storage 50 and the power line to transmit and receive power.

In an embodiment of the present invention, the external power client 60 is provided in plural and provides a charging system in which a user can select any one or more of them. That is, if a quick charging is desired, the user may select an external power client 60 having a higher price but faster charging. In the opposite case, the user can select a low price external power client 60. Therefore, the charging system according to the present invention may further include a display unit for allowing a user to check power information (price information, possible charging speed, chargeable amount) of the plurality of external power clients 60. That is, the user (driver) can check this price information at the same time as parking. Furthermore, power information for each client may be provided through a user's portable smart device capable of communicating with the charging system of the present invention, and selection of an external power client may also be performed through the portable smart device.

In another embodiment of the present invention, the external power client 60 may be a charge management module and a power storage that exist in a separate electric vehicle charging system. In one embodiment of the present invention, the plurality of charge management modules may include: It is possible to increase power efficiency while supplying surplus power to each other.

The electric vehicle charging system according to the present invention can be implemented not only in a building but also in an environment in which a plurality of charging systems are connected by a network. Each of the external power clients 60 may request the necessary power on a scheduler basis directly or through a management module to the charge management module and the power storage in which the electric vehicle charging system is implemented.

The parking lot monitoring and parking recognition device 16 of the present system recognizes whether an electric vehicle has entered the parking lot and transmits it to the input device 17. User authentication is performed through the input device 17, and in particular, the user inputs the maximum charging completion time information and the desired price information using the same. The maximum charge completion time is a time point at which the user of the electric vehicle wants to complete charging, and may generally be referred to as the time to leave the parking lot. Desired price information is information about a price that should not be exceeded while requesting charging of an electric vehicle.

In general, in a power system using a smart grid, the unit cost of power varies according to the time point at which power is provided. According to market economic principles, the unit price increases during times when the power consumption increases, and the unit price decreases during times when there is a large amount of surplus power due to low power usage.

Therefore, if the user has time to wait and includes a time zone with low power consumption, it is possible to charge at low unit cost. On the contrary, if the user has little time to wait and includes only the time when the power consumption is high, the user has no choice but to pay the high price.

User authentication can also be done automatically using an RFID or license plate automatic recognition system.

The system according to the present invention receives and utilizes power status and price information from a smart grid for proper operation, and needs information for operating a system such as power usage information, charging information, and user authentication information in a parking lot. . Power state and price information of the city grid is transferred to the power management device 11 is utilized. The power management device 11 delivers the power usage information to the charging scheduler 12 and the charging charging device 13 to make it available. The negotiator 14 performs a function of preferentially selecting an advantageous electric vehicle by comparing the maximum charging completion time information inputted therefrom with desired price information when there are a plurality of electric vehicles, or a plurality of external power clients 60. If present, it compares their power status and time of day price information to perform the function of selecting a favorable external power client.

In the present specification, the parking lot is a concept including a parking building or a building in which the parking lot is provided.

The charging device 15 is a structure capable of performing two-way power supply with the power storage 50 and the battery of the electric vehicle.

Hereinafter, the principle of planning the charging schedule using the maximum charge completion time and the desired price will be described. 4 is a conceptual diagram of an intelligent electric vehicle charging system according to the present invention.

The charging scheduler 12 plans a vehicle charging schedule that can best meet the price desired by the user according to the maximum charging completion time input by the electric vehicle user. Here, the maximum charging completion time is a concept of a deadline to finish charging the electric vehicle, and the desired price is a price that the electric vehicle user pays when the charging is completed. As described above, it is to be understood that there is a difference in the unit cost of power for each charging time. The charging scheduler 12 also reschedules the vehicle charging schedule according to changed information from the user (e.g., changed price information or maximum charging completion time), and the rescheduling of the vehicle charging schedule is described in more detail below. do.

An example of the vehicle A shown in FIG. 4 will be described. The maximum charge completion time of the vehicle A is relatively late. It is also assumed that the price at which the user of the vehicle A is willing to pay for charging is high.

As used herein, the term "relatively arrive late" refers to an expression that is closer to the ending time than the starting time of the entire time interval, or has a lower priority than other electric vehicles when there are a plurality of maximum charge completion times. It is a concept that means that there is. On the contrary, the phrase “coming soon” means that it is closer to the starting time than the ending time of the entire time interval, or that it is in the top of other electric vehicles when there is a large number of maximum charge completion times. It is a concept.

In addition, it is to be understood that the expression "high price" in the present specification means higher than the average price, and the expression "low price" means lower than the average price.

Since the user of the vehicle A not only takes a long time to charge, but also expresses a willingness to pay a high cost, the user of the vehicle A may meet the cost of the user of the vehicle A even if the vehicle is charged at a time having a high power unit cost. . Therefore, the charging scheduler performs charging even when the charging unit price is high.

In contrast, assume that the user of the vehicle B takes a long time to charge, but expresses a willingness to pay a low cost. Since the maximum charge deadline is sufficient, the charging schedule is selected only during the time when the charging cost is low.

Finally, the user of vehicle C has a relatively quick time to complete the maximum charge. In this case, since the problem of time is greater than the problem of cost, even if the charging unit price is high, the charging should be performed without delay.

Hereinafter, a method of providing an intelligent electric vehicle charging system will be described in detail.

First, a method of charging electric power in an electric vehicle will be described. 5 is a flowchart illustrating a method of charging power in an electric vehicle according to the present invention. It includes a charging management module installed in a parking lot for charging and parking an electric vehicle, a power storage storing and controlling power of the parking lot, and an external power client connected to and connected to the power storage by a power line. It is carried out in a containing environment.

A first step (S501) of receiving maximum charging completion time information and desired price information from a user of a parked electric vehicle, a second step of obtaining power information of a power storage and power information that can be supplied from an external power client ( S502) and a third step (S503) of planning a vehicle charging schedule that can be matched within the maximum charging completion time information and the desired price information based on the power information obtained in the second stage (S503), and the electric vehicle according to the vehicle charging schedule planning. A fourth step (S504) to charge the. Preferably, the power storage and time slot power price information of the power storage and the external power client.

In more detail, the third stage is described in detail. The unit cost of charging for each time zone is calculated based on the power information obtained in the second stage, and the amount of power available for each time zone is calculated based on the remaining power for each time zone. Within these numerical ranges, the maximum charging completion time of the electric vehicle should be included. That is, it is natural that the amount of power available for each time period accumulated up to the maximum charge completion time is greater than the amount of power charged by the electric vehicle. In addition, the total cost is calculated by multiplying the amount of power charged by the electric vehicle by the power unit price for each time zone, which means that the charging schedule should be planned so that the total cost is not greater than the user's desired price.

Furthermore, the present invention provides a power supply method of a method in which a driver reacquires power information of the supplied power storage and power information that can be supplied from an external power client, and accordingly changes the power supply scheduling accordingly. do.

Figure 6 provides an intelligent electric vehicle charging system according to another embodiment of the present invention.

Referring to FIG. 6, a fifth step in which the user receives the power information again during the fourth step of charging the electric vehicle (S504) is performed (S505). Providing power information in the fifth step may be performed through the user's portable device as described above. Then, the user re-schedules the charging schedule by inputting the maximum charging completion time and the desired price information again according to the user's needs or based on the changed power information (S506. 6th step). As described above, the replanning may be performed by a charging scheduler or the like included in the vehicle charging system according to the present invention.

For example, if the power unit price from an external client suddenly increases, power information about such a price is transferred to a user's portable terminal, a portable smart device such as a laptop, so that the user can change the charging time to another time zone or , Can be slowed down. The rescheduling schedule may be changed not only by users but also by parking lots and external clients. The electric vehicle is recharged according to the rescheduled vehicle charging schedule (S507, step 7).

The above method can be extended even when there are a plurality of electric vehicles. In this case, it is a matter of course that the amount of power that can be accumulated for a given time period up to an arbitrary time must be greater than the amount of power charged by a plurality of electric vehicles.

When the maximum charge completion time arrives relatively late and the desired price is low, it is preferable to select a time zone during which the power price for each time zone is the lowest within the maximum charge completion time to plan the vehicle charging schedule.

In contrast, when the maximum charge completion time arrives relatively late and the desired price is high, it is desirable to plan a relatively fast vehicle charging schedule within the desired price.

If the vehicle charging schedule that cannot be satisfied within the maximum charging completion time information is not possible based on the information obtained in the second step, the electric vehicle user is asked whether the vehicle is to be rapidly charged, and if the rapid charging request is received, the vehicle is rapidly charged. It is preferable to carry out.

In addition, in the present invention, even after the initial negotiation about the charging between the electric vehicle, the parking lot, and the external power client is performed, and the charging schedule is determined, various situations occur and the charging schedule determined by the initial negotiation is changed. Thus, even after a charging schedule is planned at a predetermined price, a method of resetting the charging schedule is provided through renegotiation again. For example, suppose you need to drive a car over long distances in a hurry because you're in a hurry. On the contrary, if the unit price of the power supplied from the outside is lower than the price at the initial negotiation, the driver may negotiate again with the lower charging price through renegotiation. As such, the charging system according to the present invention is not bound to the initial charging schedule at the time of charging, but the user is provided with charging information (for example, a charging price, etc.) during charging, and is charged between the parking lot and the external power client based on the charging information. An embodiment of resetting a schedule is provided.

Therefore, an embodiment of the present invention discloses a configuration in which the information is interlocked with and provided to a user's portable smart device (cell phone, smart phone, laptop, etc.) in order to provide information on charging, etc., during other tasks. That is, the user may observe the trend of the charging price through the mobile smart device owned by the user, and if the user wants to charge at a new price, the user may negotiate with the Negotiator 14 through the mobile smart device.

As another embodiment of the present invention, it is also possible to utilize the residual power of a plurality of electric vehicles parked with the power storage except for an external power client. 8 is a flowchart thereof.

This is performed in an environment including a charge management module installed in a parking lot for charging and parking a plurality of electric vehicles, and a power storage storing power of the parking lot and controlled by the charge management module.

A first step (S701) of receiving maximum charging completion time information and desired price information of each parked electric vehicle; a second step (S702) of acquiring power information of the electric power storage and power information of each parked electric vehicle; The third step (S703) of planning a vehicle charging schedule that can be matched within the maximum charging completion time information and the desired price information of each parked electric vehicle based on the information obtained in the second step, and the vehicle charging schedule planning In accordance with the fourth step (S704) for charging the electric vehicle.

Preferably, the power information of the second step is price information of the remaining power amount and the charging time of the charging time. Details thereof are similar to those of the foregoing method, and thus detailed description thereof will be omitted.

However, if the third stage is insufficient to charge the vehicle using only the power of the power storage at a specific time, the step of moving the surplus power to the power storage from the electric vehicles that are later than the current charging completion time prior to the fourth step It may further include. That is, the core of the present invention is to use the surplus power of the vehicle with a late charge completion time to complete the charging of the vehicle with a fast charge completion time, so that the charging operation can be performed without receiving external power for a predetermined time. .

In addition, as another embodiment of the present invention, a method of supplying and utilizing the remaining power of the parked electric vehicle to an external power client may be considered. 7 shows a flowchart of the process for this.

It includes a charging management module installed in a parking lot for charging and parking an electric vehicle, a power storage storing and controlling power of the parking lot, and an external power client connected to and connected to the power storage by a power line. It is carried out in a containing environment.

A first step (S601) of receiving maximum charging completion time information of a parked electric vehicle and desired price information, a second step (S602) of acquiring required power amount information and price information from an external power client and remaining power amount information of a power storage. And a third step (S603) of planning a vehicle charging schedule that can be met within the maximum charging completion time information and the desired price information based on the information obtained in the second stage, and the vehicle charging schedule matched in the third stage is If planned, a fourth step S604 of moving power of the parked electric vehicle to the power storage and a fifth step S605 of supplying power of the power storage to the external power client.

The method may further include a sixth step of charging the electric vehicle according to the vehicle charging schedule plan, and a seventh step of reducing the charging cost and the parking fee of the electric vehicle according to the power of the electric vehicle moved to the power storage in the fourth step.

When implementing such a method, the key is to plan a vehicle charging schedule that can fit within the maximum charge completion time information and desired price information. In particular, when transmitting the residual power supplied from the electric vehicle to the external power client, it should be noted that the storage power of the electric power storage within the maximum charging completion time of the electric vehicle should be more than enough to charge the electric vehicle.

In addition, as another embodiment of the present invention, it is possible to further include the step of selecting the external power client of the most favorable conditions in the process of supplying the remaining power to the external power client in the above method. 9 shows a flowchart of the process.

This includes a charge management module installed in a parking lot for charging and parking an electric vehicle, a power storage storing power of the parking lot and controlled by the charge management module, and a plurality of external powers connected to and connected to the power storage and power lines. It is run in an environment that includes clients.

A first step (S801) of receiving maximum charging completion time information of a parked electric vehicle and desired price information, a second step of acquiring required power amount and price information from a plurality of external power clients and remaining power amount information of a power storage ( S802) and a third step of selecting an external power client that can obtain the highest price while matching the maximum charge completion time information and the desired price information by reviewing the information input in the first step and the information obtained in the second step. Step S803, a fourth step S804 of planning a vehicle charging schedule that can be matched within the maximum charge completion time information and the desired price information based on the required power amount and price information of the selected external power client; and parking A fifth step (S805) of moving power of the electric vehicle to the power storage; and a sixth stage of supplying power of the power storage to an external power client. System S806 is included.

Since the details are similar to those described above, detailed descriptions will be omitted. In addition, the above technical configuration may be used independently or in combination with other configurations, which also belong to the scope of the present invention.
