Description

Electric vehicle station platform system for providing EVC charging and discharging

[0001] The present invention relates to an electric vehicle station platform system, and more specifically, to an electric vehicle station platform system for providing EVC charging and discharging.

[0002] With the recent rapid increase in the adoption rate of electric vehicles (EVs), the demand for EV charging infrastructure is also rising significantly. EVs offer the advantages of being eco-friendly and highly energy-efficient compared to conventional internal combustion engine vehicles. However, if EV charging infrastructure is insufficient, issues such as increased waiting times and poor accessibility to charging stations may arise. In particular, existing EV charging stations face significant limitations in terms of charging efficiency and user convenience due to a lack of sufficient power infrastructure and management systems.

[0003] The first problem relates to the energy sources of charging stations. Conventional charging stations are primarily supplied with electricity from fossil fuel-based power grids, making them not only unfriendly but also resulting in relatively high electricity costs. Charging stations that do not utilize renewable energy have low energy efficiency and contradict the original purpose of electric vehicles, which is to reduce carbon emissions. Furthermore, in some regions, providing stable charging services is difficult due to the instability of the power supply.

[0004] The second problem stems from the lack of protection for charging equipment and facilities. Existing charging stations lack adequate systems to protect facilities from the external environment, posing a high risk of damage to charging equipment due to weather conditions such as rain, snow, and lightning. If expensive equipment like ESS is damaged by these environmental factors, repair costs increase, and the operational efficiency of the charging station can be significantly reduced. In particular, if immediate response is difficult in the event of equipment damage, it results in an inability to provide stable charging services to users.

[0005] The third issue is the lack of data collection and analysis related to charging station operations. Existing charging stations lack adequate systems for collecting and analyzing real-time data, such as user patterns, charging efficiency, and energy consumption. Consequently, operators find it difficult to efficiently manage the operational status of charging stations and make improvements tailored to user demand. While energy consumption patterns and user congestion may vary from station to station, the inability to collect and analyze this information in real time leads to a decline in both operational efficiency and user convenience.

[0006] Finally, there is also the issue of the lack of an interaction system between users and administrators. Existing charging stations primarily provide only simple charging functions, with virtually no additional service features such as waiting list registration, personalized notifications, or fault reporting. Users find it difficult to monitor the charging station's status in real time, and administrators find it difficult to immediately check the condition or malfunction of charging equipment. Consequently, it is difficult to take appropriate measures when charging waiting times become prolonged or equipment failures occur.

[0007] As such, conventional electric vehicle charging station systems have various limitations in terms of energy efficiency, weather protection, data collection and analysis, and user interaction. To improve this, a new electric vehicle charging infrastructure is required that features enhanced energy efficiency through the use of renewable energy, strengthened protection of facilities from external environments, real-time data-based operational management, and the provision of customized functions for users.

[0008] The objective of the present invention is to provide an electric vehicle station platform system for providing EVC charging and discharging that can build an infrastructure for providing EV charging services that conforms to local power requirements, electrical design regulations, electrical design technical standards, and local environmental conditions of countries around the world, configure an infrastructure for providing EV charging services through facilities such as renewable energy, ESS, PCS, AMI, and fast / slow chargers, build facilities such as batteries, PCS, HVAC, and XEMS through separate containers, install and operate in grid-connected and off-grid types, and operate safely with facilities for protection considering local weather conditions such as lightning strikes and rainy season.

[0040] Throughout this specification, when it is stated that one component is located "on" another component, this includes not only cases where one component is in contact with another component, but also cases where another component exists between the two components. Throughout this specification, when it is stated that a part "includes" a component, this means that, unless specifically stated otherwise, it does not exclude other components but may include additional components.

[0041] FIG. 1 shows a schematic diagram illustrating the configuration of an electric vehicle station platform system for providing EVC charging and discharging according to an embodiment of the present invention, FIG. 2 shows a block diagram illustrating an electric vehicle station platform system for providing EVC charging and discharging according to an embodiment of the present invention, and FIG. 3 shows a plan view illustrating a design example in which an electric vehicle station platform system for providing EVC charging and discharging according to an embodiment of the present invention is arranged.

[0042] Referring to these drawings, the electric vehicle station platform system (100) for providing EVC charging and discharging according to the present embodiment is equipped with a renewable energy generation operation unit (110), an ESS operation unit (120), an electric vehicle power provision unit (130), and a service platform provision unit (140) that perform specific roles, thereby enabling the construction of an electric vehicle charging service provision infrastructure that meets the local power requirements, electrical design regulations, electrical design technical standards, and local environmental conditions of various countries around the world, and can configure an electric vehicle charging service provision infrastructure through facilities such as renewable energy, ESS, PCS, AMI, and fast / slow chargers, and can construct facilities such as batteries, PCS, HVAC, and XEMS through separate containers, and can be installed and operated in a grid-connected type and an off-grid type, and can be safely operated together with facilities for protection considering local weather conditions such as lightning strikes and rainy season.

[0043] The electric vehicle station platform system (100) for providing EVC charging and discharging consists of two main operating methods: an independent operating method and a grid-connected operating method. These two operating methods are selected based on the installation environment of the charging station and the power supply method, and each method is designed to provide optimal charging services in specific situations.

[0044] (1) Standalone operating method

[0045] The standalone operation method operates independently of the power grid, where the charging station is not connected to the main power grid but independently produces and uses electricity through its own power supply system. In this method, renewable energy sources such as solar and wind power are primarily used as power sources, and an Energy Storage System (ESS) plays a key role in charging and discharging. The specific characteristics of the standalone operation method are as follows.

[0046] Utilization of Renewable Energy Sources: In off-grid operation, a power grid is not required, so renewable energy sources such as solar and wind power are utilized as the primary power supply. As a result, charging stations operate in an environmentally friendly manner, offering the advantage of reducing carbon emissions.

[0047] ESS-based power storage and management: The ESS operation unit (120) stores power produced from renewable energy sources and supplies power according to the needs of the charging station. The charging station can produce power from solar energy during the day and store it in the ESS, and use the stored power to provide electric vehicle charging services at night or when weather conditions are poor.

[0048] Emergency power notification function: The power status of the ESS is monitored in real time through the service platform provider (140), and if the remaining battery level of the ESS drops below a certain level, an emergency power maintenance notification is provided to the manager via a smart device. Through this, the manager can identify and prepare for a power shortage situation at the charging station in advance.

[0049] Self-sufficient Charging Station Model: Since the independent operation method does not rely on the external power grid, charging station operations are not affected even if external power supply issues occur. This enables the provision of stable electric vehicle charging services even in areas far from the city center or remote locations without power grids.

[0050] (2) Grid-connected operation method

[0051] Grid-connected operation is a method of operation in which charging stations are connected to the main power grid to receive power when needed. This operation method guarantees a stable power supply through the grid and supports efficient power usage through integration with renewable energy and ESS. The specific characteristics of grid-connected operation are as follows.

[0052] Grid Connection: Since the charging station is connected to the main power grid, it can supplement the necessary power from the main power grid if the power provided by renewable energy or ESS is insufficient. This allows for the stable provision of electric vehicle charging services even under weather conditions where renewable energy generation is limited.

[0053] Power efficiency optimization: In grid-connected operation, power efficiency can be optimized as the ESS is linked with the power grid. For example, when renewable energy is abundant, surplus power is efficiently utilized by storing it in the ESS or sending it to the power grid, and when energy is insufficient, it is supplemented through the power grid.

[0054] AMI (Advanced Metering Infrastructure) Communication System Integration: The grid-connected operation method can collect and manage power consumption data in real time through the AMI grid-connected communication system (160). Through this, the charging station operator can monitor and efficiently manage the status of power consumption, and optimize power management through data communication.

[0055] Electricity usage fee calculation and user management: In the grid-connected operation method, fees can be charged to users based on the amount of electricity supplied from the main power grid, and payment can be easily made through various payment methods such as QR payment. A customized settlement system (170) handles payment and settlement, and customized fees are charged based on the charging method (fast, slow, etc.) and electricity usage.

[0056] V2G (Vehicle-to-Grid) and V2V (Vehicle-to-Vehicle) support: In grid-connected operation mode, V2G functionality is available to support bidirectional power flow between electric vehicles and the power grid. This enables V2V functionality, which allows surplus power from electric vehicle batteries to be supplied to the power grid or to other electric vehicles. Through this, flexible power management is possible, allowing power to be supplied using electric vehicle batteries during peak demand and stored again when demand is low.

[0057] As such, standalone and grid-connected operation methods can be selected according to the installation environment and power demand, and the system is designed to provide efficient and stable electric vehicle charging services by leveraging the advantages of each.

[0058] Hereinafter, each component constituting the electric vehicle station platform system (100) for providing EVC charging and discharging according to the present embodiment will be described in detail with reference to the drawings.
