[Method and Apparatus for Communication for Charging Electric Mobility Using Additional Information Related to an Automated Connection Device]
[0002] Electric vehicles (EVs) currently under development use battery power to drive a motor, and thus have the advantages of producing fewer air pollutants such as exhaust gases and noise, being less prone to breakdowns, having a longer lifespan, and being easier to drive than conventional gasoline engine vehicles.
[0003] Electric vehicles are categorized by their propulsion system into hybrid electric vehicles (HEVs), plug-in hybrid electric vehicles (PHEVs), and electric vehicles (EVs).

EMAID can be introduced as a temporary identifier that can be assigned using different authentication methods for temporary, short-term single contracts, such as family vehicles or car-sharing contracts. Since one person can have an EMAID for each of multiple contracts, it can be used for purposes different from personal identification information.
[0113] In this disclosure, vehicle-to-grid (V2G) communication is defined in the ISO 15118 standard and can be designed to correspond to the 7-layer OSI. In other words, OSI (Open Systems Interconnection) can be "a conceptual model for standardizing the communication functions of a communication or computing system regardless of the internal structure and technology involved."
[0114] The ISO 15118 standard is designed to establish and implement charging and payment processes for electric vehicles. Another key feature is its ability to adopt and leverage various information and communication technologies. While it includes information and communication technology elements mapped to the seven layers of the OSI model, its primary purpose is to establish charging and payment processes for electric vehicles, so application-specific features are primarily addressed.
[0115] The V2G communication interface defined by the ISO 15118 standard can include digital, IP-based protocols. Communication between the electric vehicle (EV) and the electric vehicle power supply (EVSE), as well as between the electric vehicle power supply (EVCC) and the supply equipment communication controller (SECC), can be included within the V2G communication interface defined by the ISO 15118 standard.
[0116] The V2G communication interface and ISO 15118 standard may be intended to enable user-friendly mechanisms for authentication, authorization, and payment at charging stations without requiring separate user interaction.
[0117] Electric vehicles can be integrated into the smart grid to provide flexible load control and valuable grid services that accommodate diverse driver habits without compromising them. To avoid the need for additional grid components to supply power during peak demand due to highly variable load fluctuations, the energy from electric vehicles can be considered as an energy source within the smart grid. Furthermore, providing appropriate incentives for electric vehicles can be considered to promote the smart grid's long-term expansion of renewable energy.
[0118] The Vehicle-to-Grid Transfer Protocol (V2GTP) at Layer 5 of the OSI model can be fundamentally understood as a session wrapper for application-layer messages. These application-layer messages can be referred to as vehicle-to-grid (V2G) messages. The V2GTP protocol can include header and payload definitions that enable efficient identification and processing of V2G messages.
[0119] The Automated Connection Device / Automatic Charging Device / Automatic Charging Device (ACD) technology can be implemented based on the content specified in ISO / IEC 15118 Edition 2, ISO 15118-20 to perform at least part of the charging process by controlling a robot or automated device using wireless communication.
[0120] As examples of ACD technology, types such as ACD-U (Underbody), ACD-S (Sidearm), ACD-P (Pantograph), or ACD-R (Roof) have been proposed based on the direction in which the ACD equipment on the EVSE side approaches the electric vehicle and / or the location of the ACD equipment on the EVSE side with respect to the electric vehicle, and additional ACD types may be included in the future as wired / wireless charging technology expands.
[0121] The ACD charging and charging communication methods for ACD charging described below can be configured to define a new name space, change message parameters, change message sequences, and utilize the docking-undocking-pairing mechanism in ACD charging communication of ISO 15118 over WLAN. In addition, the ACD charging communication method can be configured to define VSE additional information parameters for ACD-U, ACD-S, ACD-P, or ACD-R.
[0122] VSE (Vendor Specific Element) may refer to a data format that contains information about the type of EVSE available at the current location in ISO 15118-based communication.
[0123] In the present disclosure, for the convenience of explanation, when the main embodiments include an electric vehicle, a charging station for an electric vehicle, an electric vehicle power supply equipment (EVSE) of a charging station, or an ACD-based charging infrastructure, the technical features of these embodiments can be modified and applied to chargeable mobility or devices, charging stations for chargeable mobility or devices, and power supply equipment of a charging station in alternative embodiments of the present disclosure.
[0124] Even when the term "electric vehicle" or "vehicle" is used for convenience in this disclosure, the present invention can be applied to various types of electric mobility capable of running using electric energy. In this context, "electric mobility" can refer not only to mobility powered solely by electric energy, but also to various types of hybrid electric mobility capable of utilizing other energy sources.
[0125] Even when targeting various electric mobility, rechargeable mobility, or devices, expressions such as EVSE (Electric Vehicle Supply Equipment) can conventionally refer to devices that supply electric energy or charging infrastructure, and expressions such as EVCC (Electric Vehicle Communication Controller) can refer to a controller that performs electronic communication and control within electric mobility, rechargeable mobility, or devices. A SECC (Supply Equipment Communication Controller) can refer to a controller that performs electronic communication and control that affects the operation of a charger or charging infrastructure in relation to a charger or charging infrastructure.
[0126] Hereinafter, a preferred embodiment according to the present invention will be described in detail with reference to the attached drawings.
[0127] Figure 1 is a conceptual diagram illustrating an example of a system including charging infrastructure for transmitting power to an electric vehicle.
[0128] Referring to FIG. 1, the electric vehicle charging process can be performed by at least one component of an electric vehicle (10) and a charging station (charging station), and can be used to transmit power to the electric vehicle (10) wired or wirelessly.
[0129] An electric vehicle (10) according to an embodiment of the present invention may include a hybrid vehicle having both an electric motor and a general internal combustion engine, and may include not only an automobile but also a motorcycle, a cart, a scooter, and an electric bicycle.
[0130] Here, an electric vehicle (10) can be generally defined as a vehicle (automobile) that supplies current induced from a rechargeable energy storage device, such as a battery (12), as an energy source for an electric motor, which is a power device.
[0131] In addition, the electric vehicle (10) may include a power receiving device / pad (11) including a receiving coil to wirelessly charge the battery (12), and may also include a plug connection to wiredly charge the battery (12). In this case, an electric vehicle (10) capable of wiredly charging the battery (12) may be referred to as a plug-in electric vehicle (PEV).
[0132] Here, the charging station / charging station can be connected to a power grid (30) or power backbone and can provide alternating current (AC) or direct current (DC) power to a power transmitting device / pad (21) including a transmitting coil via a power link.
[0133] In addition, the charging station can communicate with the power grid (30) or the infrastructure management system or infrastructure server that manages the power grid (30) through wired or wireless communication, and can perform wireless communication with the electric vehicle (10). Here, the wireless communication may include Bluetooth, Zigbee, cellular, a wireless local area network, etc.
[0134] Additionally, for example, the charging station / charging station may be located in various locations, such as a parking lot attached to the home of an electric vehicle owner (10), a parking area for charging electric vehicles at a gas station, a parking area at a shopping center or workplace, etc.
[0135] Here, the process of charging the battery (12) of the electric vehicle (10) wired / wireless can be performed by first positioning the power receiving device / pad (11) of the electric vehicle (10) in an energy field by the power transmitting device / pad (21), and allowing the transmitting coil of the power transmitting device / pad (21) and the receiving coil of the power receiving device / pad (11) to interact or couple with each other. As a result of the interaction or coupling, electromotive force is induced in the power receiving device / pad (11), and the battery (12) can be charged by the induced electromotive force.
[0136] Additionally, the charging station / charging station and the power transmission device / pad may be referred to in whole or in part as a supply power circuit (SPC) or a ground assembly (GA, 20), and the SPC or ground assembly may refer to the meaning defined above.
[0137] In addition, the power receiving device / pad (11) of the electric vehicle (10) and all or part of other internal components of the electric vehicle may be referred to as an electric vehicle power circuit (EVPC) or vehicle assembly (VA), where the EVPC or vehicle assembly may refer to the meaning defined above.
[0138] An electric vehicle charging system may include, but is not limited to, a conductive charging system using cables or a non-contact wireless power transmission system. An electric vehicle charging system can be fundamentally defined as a system that charges a battery (12) mounted on an electric vehicle (10) using power from a commercial power distribution network (grid. 30) or an energy storage device. Such an electric vehicle charging system may take various forms depending on the type of electric vehicle (10).
[0139] For example, SAE TIR J2954, a leading standard for wireless charging, establishes industry-standard specification guidelines that define interoperability, electromagnetic compatibility, minimum performance, safety, and testing acceptance criteria for wireless charging of light-duty electric and plug-in electric vehicles. Those skilled in the art will readily understand that similar guidelines can also be applied to wired charging systems.
[0140] The wired / wireless charging system for electric vehicles can largely include the following three elements:
[0141] 1) GA coil for power connection and grid connection power converter, communication link with vehicle system
[0142] 2) VA coil with rectifier and filtering components and charging control power electronics for regulation / safety / shutdown if required, and communication link to base station side.
[0143] 3) Related modules required for secondary energy storage system, battery management system components and in-vehicle communication (CAN, LIN) required for battery SOC, charge rate and other necessary information.
[0144] Additionally, the VSE Field of WLAN does not contain detailed information such as maximum charging power, which may prevent users from properly connecting to the charger they actually want to charge at a charging station where one SECC and multiple EVSEs coexist.
[0145] In addition, after the vehicle is associated with the charger / SECC and WLAN Association, a positioning procedure must be performed to ensure precise alignment between the vehicle and the EVSE. In the case of wireless charging (WPT), if the vehicle pad and the EVSE pad are not properly aligned, charging efficiency may decrease or charging may become impossible. In addition, after positioning is complete, a procedure is required to check whether a physical connection with the EVSE to be connected is possible. If a physical connection with the EVSE to be charged is not possible, charging will not proceed. Therefore, a pairing procedure must be performed between the vehicle and the EVSE after WLAN Association. For this purpose, in the case of wireless charging, a method for positioning and pairing using a separate P2PS (Point to Point Signal) is defined in the IEC 61950-2 standard. However, in the case of a robotic charging system based on an automatic coupling device (ACD), there is room for improvement, such as insufficient standard regulations for separate positioning and pairing methods.
[0146] Power transfer can be accomplished from a transmitting coil / primary coil (L1) to a receiving coil / secondary coil (L2). At this time, the resonance frequencies of the transmitting coil (L1) and the receiving coil (L2) can be configured to be similar or the same, and the receiving coil (L2) can be configured to be positioned at a close range to the electromagnetic field generated by the transmitting coil (L1).
[0147] Meanwhile, since power loss may increase as the distance between the transmitting coil (L1) and the receiving coil (L2) increases, setting the positions of the two may be an important factor.
[0148] At this time, the transmitting coil (L1) may be included in the power transmitting device / pad, and the receiving coil (L2) may be included in the power receiving device / pad. In addition, the transmitting coil may be referred to as a primary coil or a GA coil (Ground Assembly coil), and the receiving coil may be referred to as a secondary coil or a VA coil (Vehicle Assembly coil). Therefore, the determination of the positions between the power transmitting device / pad and the power receiving device / pad or the determination of the positions between the electric vehicle (10) and the power transmitting device / pad are also important factors.
[0149] The positional alignment between the power transmission device / pad in FIG. 1 and the power reception device / pad built into the electric vehicle (10) may correspond to the previously described term alignment, and therefore may be defined as the positional alignment between the SPC / GA and the EVPC / VA, and is not limited to the positional alignment of the power transmission device / pad and the power reception device / pad.
[0150] There may be embodiments in which a separate cover is placed for the inlet, which is a charging socket installed in the vehicle. If the inlet cover is placed inside the charging door / port, the inlet cover may be implemented with a plastic or rubber component for insulation.
[0151] The charging manipulator may be or include various types of devices referred to as ACD (Automated connection device, Automatic Charging Device, Autoconnect Charging Device).
[0152] Examples of charging manipulators can also be applied to types ACD-S (Side), ACD-U (Underbody), ACD-P (Pantograph) or ACD-R (Roof).
[0153] In one embodiment of the present invention, the movable range of the charging manipulator may refer to the ACD mating space. In an alternative embodiment of the present invention, the movable range of the charging manipulator may refer to the range of space where the movable distance of the charging manipulator and the ACD mating space are combined.
[0154] In one embodiment of the present invention, a process for identifying the type and specifications of an electric vehicle (10) may be included. At this time, the operating range of the charging manipulator may be adjusted in consideration of the operating range of the manipulator of the electric vehicle (10), which is the ACD counterpart, to determine whether mating is possible.
[0155] The charging system of FIG. 1 may utilize one or more of wired power transfer or wireless power transfer. The ACD-based charging system of FIG. 1 may support either wired or wireless charging technology, regardless of whether it is an ACD-U, ACD-S, ACD-P, or ACD-R.
[0156] If the charging system of Fig. 1 is a wireless power transmission system, it is generally known to utilize inductive coupling, and the power transmission system according to one embodiment of the present invention may adopt a configuration in which power is transmitted by inductive coupling under the premise that the gap between the transmitting pad and the receiving pad is controlled within a certain range. At this time, the configuration of Fig. 1 may be utilized within a range consistent with the purpose of the present invention, and may be selectively utilized or appropriately modified as needed.
[0157] The international standard for wireless communication for electric vehicle charging, 15118-8, allows vehicles to connect to a charger AP rather than a general AP through the VSE (Vendor Specific Element) field of the MAC Frame, which corresponds to Layer 2 of the OSI 7 Layer. However, information regarding positioning and pairing is not properly defined within the VSE field of the charger / SECC, except for wireless power transfer (WPT). Therefore, in a charging manipulator system based on an automatic connection device (ACD), such as the ACD-U (Underbody) type or ACD-S (side) type, various positioning and communication techniques can be applied to achieve precise positioning and pairing through this.
[0158] The on-board vehicle power supply circuit installed in the electric vehicle (10) may include a battery (12) as a load.
[0159] The power receiving pad / device (11) mounted in the electric vehicle (10) can receive power via a secondary coil and transmit it to the battery (12).
[0160] An electric vehicle charging station is shown as part of an EVSE for supplying power to an electric vehicle (10). The charging station is electrically connected to an ACD station, and power can be transmitted to the vehicle via a connector of the ACD station.
[0161] The primary coil on the EVSE side and the secondary coil on the electric vehicle (10) side can be close together to form an inductive coupling.
[0162] In an ACD-U type electric vehicle wireless charging system according to one embodiment of the present invention, the ACD station is located below the electric vehicle (10), and this structure can be collectively referred to as the ACD-U type.
[0163] In some embodiments, the connector on the ACD side may be controlled to protrude from the station and approach the vehicle side. In this case, the connector may be connected and controlled by a robot arm.
[0164] In some embodiments, the vehicle-side connector may be controlled to protrude from the vehicle side and approach the ACD-side connector. In this case, the vehicle-side connector may be connected and controlled by a robot arm.
[0165] In an electric vehicle wireless charging system of the ACD-S type according to one embodiment of the present invention, the ACD station is located next to the electric vehicle (10), and this structure may be collectively referred to as the ACD-S type.
[0166] In some embodiments, the connector on the ACD side may be controlled to protrude from the station and approach the vehicle side. In this case, the connector may be connected and controlled by a robot arm.
[0167] In some embodiments, the vehicle-side connector may be controlled to protrude from the vehicle side and approach the ACD-side connector. In this case, the vehicle-side connector may be connected and controlled by a robot arm.
[0168] As a coordinate system applicable to one embodiment of the present invention, reference may be made to the x, y, and z-axis coordinate system specified in SAE J2954.
[0169] In one embodiment of the present invention, in a right-handed coordinate system, the forward or front-back direction of a vehicle can be defined as the + / -X axis direction. In addition, the driver side for a left-handed vehicle or the left and right sides of the vehicle can be defined as the + / -Y axis direction. In addition, the upward or up-down direction of the vehicle can be defined as the Z axis.
[0170] In the power transmission system of FIG. 1, the power transmitting pad (21) and / or the power receiving pad (11) may include a power circuit for power supply.
[0171] In an embodiment of a wired power transmission device, power circuits may be included on both the power transmitting side and the power receiving side.
[0172] A DC / AC conversion circuit, a compensation circuit, etc. may be included between the grid (30) side and the power transmission pad (21) or the wired power transmission device.
[0173] A rectifier circuit, an AC / DC conversion circuit, a compensation circuit, etc. may be included between the power receiving pad (11) or the wired power receiving device and the battery (12).
[0174] FIG. 2 is a diagram conceptually illustrating a communication architecture between electric mobility and charging infrastructure according to one embodiment of the present invention.
[0175] Referring to FIG. 2, the SECC (210) on the charging infrastructure or EVSE (200) side can perform charging communication using wireless LAN (WLAN) with the EVCC (110) on the mobility (100) side.
[0176] At this time, WLAN charging communication may refer to, but is not limited to, ISO 15118-20 or ISO 15118-8 standards.
[0177] The ACD Infra (220) on the charging infrastructure or EVSE (200) side can communicate with the ACD Vehicle (120) on the mobility (100) side using a Point-to-Point Signal (P2PS). In this case, additional information can be exchanged during the P2PS communication between the ACD Infra (220) and the ACD Vehicle (120). The additional information can include information for guiding, pairing & positioning, and docking / coupling.
[0178] At this time, although it is expressed as ACD Vehicle (120) in FIG. 2, in the present disclosure, ACD Vehicle (120) refers to an ACD placed in a rechargeable mobility or device, and is not limited to an ACD of a special vehicle.
[0179] In one embodiment of the present invention, the ACD Infra (220) and the ACD Vehicle (120) may include a PPD (Pairing & Positioning Device) capable of supporting precise positioning using P2PS communication technology.
[0180] At this time, at least one PPD is placed on the mobility (100) and / or charging infrastructure side and may include a module that can measure the distance to another device or determine location information using wireless signal-based ranging, etc.
[0181] The ACD Infra (220) can be assigned to each individual charger and can include a charging infrastructure-side PPD capable of precisely determining the location of the charger. The charging infrastructure-side PPD can be one or more. When there are multiple charging infrastructure-side PPDs, the relative location, distance, direction, etc. between the charging infrastructure and the mobility (100) can be precisely determined by using the measured distance or TOA / TDOA through communication between the multiple PPDs or the multiple PPDs with the mobility (100)-side PPD.
[0182] Alternatively, the ACD Vehicle (120) on the mobility (100) side may include one or more mobility PPDs. Similarly, when there are multiple mobility PPDs, the multiple PPDs can communicate with each other or with the charging infrastructure side PPD, and the relative position, distance, direction, etc. between the charging infrastructure and the mobility (100) can be precisely determined using the measured distance or TOA / TDOA.
[0183] In an alternative embodiment of the present invention, some of the multiple charging infrastructure PPDs or mobility PPDs may be selectively activated or deactivated to contribute to a more efficient positioning process. In this case, the process of selecting which of the multiple charging infrastructure PPDs or mobility PPDs to activate or deactivate for efficient positioning may be performed based on communication between the ACD Infra (220) and the ACD Vehicle (120).
[0184] When the ACD supports wired charging, docking or mating is performed between the ACD Infra (220) and the ACD Vehicle (120) to provide an electrical connection, and power can be transmitted from the charging infrastructure to the mobility (100) through the electrical connection.
[0185] In an alternative embodiment of the present invention, the ACD may support wireless charging, and coupling may be performed between the ACD Infra (220) and the ACD Vehicle (120) to transfer power from the charging infrastructure to the mobility (100).
[0186] When charging a mobility (100), the mobility (100) enters a charging station and uses WLAN (Wireless LAN) wireless communication such as 802.11n to establish a communication connection with the charger to be charged, and then perform charging.
[0187] When a vehicle enters a charging station where multiple charging infrastructures coexist, selection and communication between the vehicle and the charging infrastructure can occur.
[0188] At this time, if the range covered by the WLAN is wide enough to cover the entire charging station, an error may occur in which a SECC other than the SECC of the charging infrastructure that actually provides power to the mobility (100) communicates with the EVCC (110) of the mobility (100).
[0189] In one embodiment of the present invention, P2PS technology, which provides communication at a shorter range than WLAN, can be used to support mobility (100) to communicate with appropriate charging infrastructure and to be positioned at the location of the appropriate charging infrastructure. In one embodiment of the present invention, a communication method can be provided that utilizes P2PS communication between ACD Infra (220) and ACD Vehicle (120) to assist WLAN charging communication procedures and support accurate charging infrastructure to communicate with mobility (100).
[0190] In one embodiment of the present invention, the P2PS technology may include, for example, ultra-wideband (UWB) or low frequency (LF) communication technology. The spirit of the present invention is not limited to these specific embodiments.
[0191] Ultra-Wide Bandwidth (UWB) communications technology can allow a lot of information to be transmitted over a short period of time.
[0192] Low Frequency (LF) communication technology can ensure robustness in the guiding process.
[0193] Meanwhile, wireless LAN (WLAN) communication technology can support charging communication based on ISO 15118-20 / 8.
[0194] In one embodiment of the present invention, various heterogeneous communication technologies can be allocated and utilized for differentiated functions and roles by utilizing the unique characteristics and advantages of each communication technology.
[0195] In one embodiment of the present invention, by utilizing P2PS communication between ACD Infra (220) and ACD Vehicle (120), mobility (100) and charging infrastructure can search for and discover each other before the WLAN charging communication procedure, and thus, communication can be efficiently established without the need to repeatedly perform WLAN Association until EVSE and SECC search for each other.
[0196] In one embodiment of the present invention, precise positioning is supported by the PPD included in the ACD Infra (220) and the ACD Vehicle (120), thereby improving the safety and efficiency of the charging process.
[0197] In one embodiment of the present invention, additional functions for charging may be provided using P2PS communication between the ACD Infra (220) and the ACD Vehicle (120). These additional functions may include, for example, user authentication or authorization, electronic signatures, and viewing of user service rights. In this case, to perform the additional functions, at least one PPD included in the ACD Infra (220) and the ACD Vehicle (120) may cooperate or independently perform part of the process.
[0198] FIG. 3 is a flowchart illustrating a communication method for charging electric mobility (chargeable mobility or device) using additional information according to one embodiment of the present invention.
[0199] Including FIG. 3, a communication method for charging a chargeable mobility or device according to an embodiment of the present invention may include a discovery and connection step (S300) between a first automatic connection device (ACD, Automated Connection Device or Autoconnect Charging Device) on the chargeable mobility or device side and a second automatic connection device on the charging infrastructure side; a step (S400) of transmitting additional information for initial setup between the first automatic connection device and the second automatic connection device; a step (S500, S600) of positioning the chargeable mobility or device to a location of the charging infrastructure based on the additional information; and a step (S800) of performing communication for controlling coupling between the first automatic connection device and the second automatic connection device for charging the chargeable mobility or device based on the additional information.
[0200] The above additional information may include information for determining compatibility between the chargeable mobility or device and the charging infrastructure prior to pairing between the first automatic connecting device and the second automatic connecting device.
[0201] Additional information for determining compatibility may include the Supporting type of the ACD Vehicle and / or ACD Infra, Connector / Inlet type, Manufacturer ID, etc. In this case, the Supporting type may refer to information related to Case D / E of the ACD.
[0202] The above additional information may include information for determining the parking direction of the chargeable mobility or device prior to positioning the chargeable mobility or device.
[0203] Additional information for determining the parking direction may include the relative position of the ACD Vehicle within the mobility (or the XYZ coordinates of the ACD Vehicle). At this time, either forward parking or backward parking of the mobility may be determined based on the ACD Infra's operable range and the ACD Vehicle's position within the mobility. Information regarding changes in the relative position calibration values of the ACD Infra and the ACD Vehicle, which take forward / backward parking into account depending on the ACD Vehicle's position, may be included as Guiding Support information in the additional information.
[0204] The above additional information may include information for determining the charging infrastructure to charge the chargeable mobility or device.
[0205] Additional information for determining charging infrastructure may refer to information for designating specific ACD infrastructure. The occupancy status of the ACD infrastructure may be included as additional information.

[0206] The above additional information may include information for determining the torque of the second automatic coupling device during the process of coupling with the first automatic coupling device.
[0207] Additional information for determining torque may include height of ACD Vehicle, yaw / rall / pitch of mobility, etc., and may be used to calculate torque of ACD Infra during coupling / docking process.
