Description

Driver-customized electric vehicle charger guidance system based on charging status information

The present invention relates to an electric vehicle charger guidance system, and more specifically, to a driver-customized electric vehicle charger guidance system that guides the optimal charger that matches the type of service selected by the driver according to the driver's personality or driving situation based on charging status information. It's about.

A car runs by driving a power load such as an engine with the energy generated when burning fossil fuels such as gasoline, diesel or gas. Recently, as the problem of depletion of fossil fuels and the problem of air pollution due to excessive use has become more serious, research and development on the use of new and renewable energy and eco-friendly transportation methods are being actively conducted.

Among eco-friendly transportation methods, electric vehicles do not emit any air pollutants or cause noise pollution during operation, so automobile manufacturers around the world are rushing to launch them into the electric vehicle market. In addition, countries around the world are making efforts to develop and install electric vehicle charging systems to promote the distribution and smooth use of eco-friendly electric vehicles.

Batteries, which provide the most important power to electric vehicles, can only supply relatively less energy than existing internal combustion engine vehicles, making it difficult for electric vehicles to be activated due to their relatively short driving distances. To this end, the capacity of the battery can be increased, but due to the nature of the battery, there are limits to the size and capacity of the battery that can be installed in an electric vehicle, so there is a charging station or charging station where drivers of electric vehicles can quickly replace or charge the battery while driving. A charger guidance system is needed.

However, the current charging station or charger guidance system has limited charging information provided to drivers, and there is a problem in that drivers must select a charging station based on reasonable judgment regarding distance and cost. For example, the navigation device guides the charging station to the nearest distance or a certain surrounding area based on the driving distance, and the driver selects a specific charging station or charger among them and goes there. In this case, since the same charging station or charger is configured to guide not only the specific driver but also all other drivers, there are problems such as charging waiting time even if a specific charging station or charger is visited.

In addition, drivers can have very diverse charging conditions, such as conditions under which charging can be completed in the shortest time, conditions under which charging can be completed at the lowest cost regardless of time or distance, and even for the same driver on the same day. The above charging requirements may vary depending on the driving situation. In other words, drivers can request charger guidance services under a variety of different conditions depending on the situation.

However, the conventional charging station or charger guidance system (hereinafter referred to as 'charger guidance system') cannot guide the charger to the type according to these various situations, and has the limitation of simply providing location and charging price unilaterally.

The present invention was proposed to solve the above problems, and its task is to provide an electric vehicle charger guidance system that can guide the optimal charging station or charger that meets various conditions required depending on the driver's personality or driving situation. do.

The information managed in the history information management unit 120 is stored in the DB management unit 170 and is provided to the operation information prediction unit 130 at the request of the operation information prediction unit 130.

The operation information prediction unit 130 analyzes the driving pattern based on the accumulated charging history information for each charger 30, and predicts in advance the operation information on which charging will proceed when charging is requested. Specifically, based on the accumulated driving information, the operation information prediction unit 130 determines whether the charger is charged at the exact scheduled time, whether the charge is performed with the reserved power amount, whether charging is concentrated in a specific time zone, and whether the charger is charged at a specific driver's level. Is there any abnormal use by other drivers after recharging? If charging was not done at the scheduled time or amount of power, how often was it done? Have any breakdowns occurred during charging and how many of them? Recent A/S Analyzes patterns such as whether charging has ever been received, and according to the analyzed patterns, the probability that charging can be done immediately at the relevant time currently or at the time of reservation, the probability that charging can be done immediately for a specific vehicle, and the power demand management target. Expect operational information about charger operation, including based supply power limitation probability. Additionally, the operation information prediction unit 130 classifies and predicts the operation information by vehicle type.

Analysis of accumulated driving information and prediction of operational information for subsequent charging can be achieved by applying deep learning technology. The charger operation information predicted by the operation information prediction unit 130 is provided to the charging condition matching unit 150.

The service information request unit 140 is a component that provides charging conditions, that is, service type, to the driver for selection. Various types of charging conditions may be required for each driver, and the service information request unit 140 guides the type of service to be charged and receives charging conditions for a specific service type from the driver. As shown in FIG. 3, the types of services provided by the service information request unit 140 in this embodiment are fee reduction type (141), immediate charging type (142), reservation charging type (143), and business classification type (144). ) and market participation type (145).

The rate reduction type (141) is a service that provides guidance to chargers with low charging rates, the immediate charging type (142) is a service that provides guidance to chargers that can be charged immediately, and the reservation charging type (143) is a service that provides guidance to chargers that can be charged immediately. This is a service that provides guidance on chargers. In addition, the business classification type (144) is a service that provides guidance to businesses that provide charging services, that is, the entities that manage and operate chargers, and the market participation type (145) provides guidance to chargers to which power demand management is applied. It's a service.

Here, a charger to which power demand management is applied refers to a charger to which power use restrictions are applied through the issuance of demand response (DR) during peak power times, such as the summer in the case of Korea. Therefore, if the driver selects a market participation type of service, there may be cases where the desired amount of power cannot be charged due to power demand management, and the driver has the burden of having to endure this situation. However, drivers are configured to receive separate compensation by selecting a market participation service type. As an example, compensation may be provided in the form of paying with points or reducing fees when using a charging service in conjunction with a charging station or charger.

The market participation service type of this embodiment exemplifies a charger to which power demand management is applied according to the issuance of DR, but it can be a charger to which various types of management are applied for efficient power management.

Regarding the type of service provided by the service information request unit 140 configured as above, if the driver wants to charge at the lowest cost regardless of time, he or she will select a fee-saving service, and charge immediately regardless of the fee. If you want to recharge immediately, you will select the rechargeable service. If you want to recharge at a specific scheduled time, you will select the scheduled rechargeable service. Additionally, if a driver wants to use a charging service provided by a specific business operator, he or she will select a business-specific service, and if he or she wants to participate in stable power management, he or she will choose a market participation service.

The above service types are stored and managed in the DB management unit 170, and the service information request unit 140 transmits the service information selected by the driver to the charger matching unit 150.

It is a composition.

For example, when a fee-saving service type is selected through the service information request unit 140, the charger matching unit 150 receives expected charging operation information from the operation information prediction unit 130 and selects the service type that best matches the service type. Charging status information, such as distance from the charger, that is, distance from the electric vehicle, time, or whether charging is possible immediately, is given secondary priority, and the charger with the cheapest charging fee is given priority to match nearby chargers. As another example, when a market participation service type is selected through the service information request unit 140, the charger matching unit 150 receives charging operation information from the operation information prediction unit 130 and performs power demand management according to the issuance of DR. Match the applicable charger. At this time, the charger matching unit 150 may match a plurality of chargers within a predetermined area based on the current location of the electric vehicle.

The charger information unit 160 is a component that provides information on chargers matched by the charger matching unit 150. Depending on the service type, the charger information unit 160 provides charging information such as the location of the charger, current status, charging fee, charging time to full charge, amount of power supplied, and expected charging limit time (expected DR issuance time). Therefore, the driver can check information about one or more chargers provided, visit one charger, and proceed with immediate or scheduled charging.

The DB management unit 170 stores and manages information such as the charger, charger operation information, expected operation information, service type, electric vehicle using the charger, and driver using the charger, and the operation information prediction unit 130, requests service information. Stored information is provided upon request from the unit 140, the charger matching unit 150, or the charger information unit 160. The DB management unit 170 stores and manages information about each charger based on the charger identification code.

The control unit 180 controls the operation of each component of the charger guidance system 100. That is, the control unit 180 controls the driving information collection unit 110 to collect driving information when a specific charger is driven, controls the history information management unit 120 to accumulate and manage the collected driving information, and controls each charger. The operation information prediction unit 130 is controlled to predict the state of charge. In addition, the control unit 180 controls the service information request unit 140 to receive a service type input from the driver, and controls the charger matching unit 150 to find an optimal charger according to the input service type. The charger guide unit 160 is controlled so that the matched charger is provided through the display means.

Additionally, the control unit 180 separately manages information on drivers or electric vehicles using market participation-type services. The control unit 180 provides compensation in the form of points, etc., to the relevant driver or electric vehicle according to the performance of using the market participation service, and allows the provided points to be used as a fee for later use of the charger. Therefore, from the driver's perspective, power demand management can be applied to compensate for the burden of not being able to charge with a sufficient amount of power, and from the charger operator's perspective, chargers subject to power demand management are actively used, thereby participating in the power demand management market. can be done actively.

In this way, the charger guidance system of this embodiment monitors the operation of the charger in real time and utilizes the charging status information collected as a database to match and guide the optimal charger suitable for the service type selected by the driver, thereby improving driver satisfaction.
