Description

Technical Field

[0001] This invention belongs to the technical field of electric vehicle (EV) charging.

[0002] EV charging stations (also known as EV chargers or electric vehicle supply equipment (EVSE)) are designed to supply power to charge plug-in electric vehicles.

[0003] EV charging stations can be located in private or public areas.

[0004] Specifically, the present invention relates to a method for setting up and installing electric vehicle (EV) charging equipment. Background Technology

[0005] EV charging equipment may include, for example, one or more electric vehicle supply units (EVSEs).

[0006] For example, EVSE (also known as "wallbox") can be a module that is applied to or included in a wall or similar for the purpose of supplying power to an electric vehicle to be charged.

[0007] In its latest development, EVSE can be connected to backend systems, such as for user access control management and energy billing (the so-called "smart" EVSE).

[0008] With current technology, the field installation and setup of EVSEs typically requires complex steps, resulting in a time-consuming process that necessitates the intervention of specialized technicians.

[0009] Figure 1 The diagram illustrates examples of field installation and setup methods for “smart” EVSEs based on current technology levels.

[0010] At the current level of technology, "intelligent" EVSEs are delivered to users by manufacturers in an unconfigured state.

[0011] Therefore, intervention by a specialist is necessary to configure one or more EVSEs onto an available network (or similar connectivity channel) and to set up one or more EVSEs for connecting to a backend system (e.g., a backend management platform).

[0012] For this purpose, it is necessary to define identification information for one or more EVSEs (e.g., identifiers and keys or passwords, certificates, public / private key pairs, or the like) and configure backend systems to connect to one or more EVSEs.

[0013] At the current level of technology, the setup of a "smart" EVSE can be based on the following standards and protocols: Connectivity: 2G / 3G / 4G / 5G standards; Wi-Fi connectivity; Ethernet connection.

[0014] Application Protocol: Open Charging Point Protocol (OCPP) (currently referring to version 1.6, but also applicable to versions 1.5, 2.0, 2.0.1, or similar); Proprietary manufacturer-specific application protocols.

[0015] Therefore, an improved solution is needed that allows for simplified setup and field installation of EV charging equipment (e.g., containing one or more EVSEs), thereby reducing the total cost without compromising the functionality of the EV charging equipment (especially "smart" features). Summary of the Invention

[0016] Therefore, one object of the present invention is to provide a method and system that allows for simplified and cost-effective setup and field installation of EV charging devices (e.g., one or more EVSEs) without compromising their functionality, especially their “smart” features.

[0017] This objective is achieved by providing the method according to claim 1.

[0018] The present invention provides a method for setting up and installing electric vehicle (EV) charging equipment.

[0019] Specifically, an EV charging device may include one or more EVSEs configured and adapted to implement “smart” functions such as user access control management and energy consumption billing.

[0020] The method includes steps for defining identification information for EV charging devices.

[0021] Specifically, the identification information of an EV charging device may include the serial number of the EV charging device.

[0022] The method further includes the step of defining configuration information for the EV charging device.

[0023] In addition, the method includes the step of defining public key pairs for the backend system.

[0024] The method further includes the step of uploading the defined identification information and configuration information of the EV charging device to the EV charging device.

[0025] The method further includes the step of uploading the defined identification information and configuration information of the EV charging device to the backend system.

[0026] This step can be performed at any time between the manufacture of the EV charging equipment and its field installation.

[0027] The method further includes the step of installing EV charging equipment on-site.

[0028] EV charging equipment can be installed in private or public areas.

[0029] The method further includes the step of connecting the EV charging device to the back-end system via a network.

[0030] The method further includes performing a setup step for the EV charging device, the setup step including transmitting setup information of the EV charging device, containing the public key of the backend system, from the backend system to the EV charging device via an installation channel.

[0031] The installation channel is at least temporarily established between the EV charging equipment and the back-end system.

[0032] Because the EV charging device's setup information includes the backend system's public key, the EV charging device can accept only messages signed with the backend system's private key. Furthermore, since the EV charging device's identification and configuration information is defined and uploaded to both the EV charging device and the backend system at an earlier stage, no further setup of the EV charging device is required after field installation.

[0033] Instead, it is sufficient to connect EV charging devices to a power source such as an electrical network and establish a connection to the back-end system.

[0034] Therefore, time-consuming operations that require specialized personnel to intervene can be prevented.

[0035] This invention is based on the following basic idea: by defining the identification and configuration information of the EV charging device and uploading the defined identification and configuration information to both the EV charging device and the backend system before installation, the EV charging device can be set up and installed in a simplified and cost-effective manner without compromising its functionality, especially its "smart" function.

[0036] The "smart" features of EV charging equipment may include user access control management and energy consumption billing.

[0037] Advantageously, the installation channel can be defined by an installation application running on the user's mobile device (e.g., smartphone, tablet, or the like).

[0038] Specifically, the configuration information of the EV charging device 20 may include one or more of the following: Public / private key pairs for EV charging devices; The public key of the cloud storage component; Name of EV charging equipment; One or more configuration options for EV charging equipment; EV charging device load management settings, and / or One or more safety features of EV charging devices.

[0039] Alternatively, the configuration information for the EV charging device may include one or more of the following: Local network configuration parameters; One or more access parameters; Cloud management platform network address; One or more certificates for EV charging equipment, and / or One or more OCPP parameters for EV charging equipment.

[0040] Advantageously, the setup process for EV charging devices can be accomplished by recording the public key of the backend system and the identification information (especially the serial number) of the EV charging device.

[0041] Therefore, it is possible to identify the serial number of the EV charging device and thereby discover the correct public key in the backend system for encrypting / signing messages containing the configuration information of the EV charging device.

[0042] The public key of backend system 10 can be defined based on an X.509 certificate.

[0043] X.509 is an International Telecommunication Union (ITU) standard that defines the format of public key certificates.

[0044] Specifically, X.509 certificates use digital signatures to bind identity to a public key.

[0045] Defined identification and configuration information can be recorded in the manufacturing log file of the EV charging device.

[0046] This is typically done during the manufacturing of EV charging equipment.

[0047] Alternatively, the pre-configured identification and configuration information of the EV charging device can be set in an embeddable hardware component.

[0048] Next, the embedded hardware components can be installed into the EV charging device.

[0049] Pre-configured identification and configuration information is typically obtained by the manufacturer when procuring or delivering embeddable hardware components.

[0050] A temporary connection can be established between EV charging equipment (e.g., one or more EVSEs) and the backend system.

[0051] Specifically, a temporary internet connection can be used to establish a connection between the EV charging device and the back-end system.

[0052] Alternatively, a static Internet connection can be used to establish a connection between the EV charging device and the back-end system.

[0053] A connection between the EV charging device and the back-end system can be established via Wi-Fi.

[0054] In this scenario, the EV charging device uses a stored network name and password provided during manufacturing to connect to an open network or a pre-configured Wi-Fi Service Set Identifier (SSID), and obtains an Internet Protocol (IP) address via Dynamic Host Configuration Protocol (DHCP).

[0055] Next, a connection to the backend system is established using a pre-configured backend address.

[0056] Finally, the authentication process is performed using the defined identification and configuration information of the EV charging device.

[0057] Alternatively, an Ethernet-based connection can be used to establish the connection between the EV charging device and the back-end system.

[0058] In this case, the IP address is obtained through DHCP.

[0059] In the case of an Ethernet-based connection, the connection and authentication steps are the same as those specified above.

[0060] Alternatively, the connection between EV charging equipment and the back-end system can be based on 3G / 4G / 5G standards.

[0061] In this scenario, the EV charging device connects to the network using a pre-configured access point name (APN) setting, which uses pre-programmed data and / or data provided in the EV charging device's SIM module.

[0062] The method may further include steps for defining network-level access data for EV charging devices.

[0063] Specifically, network-level access data may include Wi-Fi network names.

[0064] Alternatively, network-level access data may include Wi-Fi network passwords.

[0065] Alternatively, network-level access data may include APN settings.

[0066] The present invention further provides a system for implementing the method described above.

[0067] The system contains at least one backend system.

[0068] The system further includes EV charging equipment.

[0069] The EV charging equipment is configured and adapted to be connected to the back-end system via a network in an operational manner.

[0070] The characteristics of EV charging equipment lie in predefined identification and configuration information.

[0071] The identification information of EV charging equipment may include the serial number of the EV charging equipment.

[0072] In addition, the backend system is characterized by predefined public key pairs.

[0073] The public key for the backend system can be defined using an X.509 certificate. The backend system includes storage components for storing defined identification and configuration information for EV charging devices.

[0074] The configuration information of the EV charging device, which includes the public key of the backend system, is transmitted from the backend system to the EV charging device through the installation channel.

[0075] The installation channel is established, at least temporarily, between the EV charging device and the backend system. As mentioned, since the EV charging device's setup information contains the backend system's public key, the EV charging device can only accept messages signed with the backend system's private key.

[0076] Advantageously, the installation channel is defined by the installation application running on the user's mobile device (e.g., smartphone, tablet, or the like).

[0077] Preferably, the EV charging device includes one or more EVSEs.

[0078] Preferably, one or more EVSEs are configured to implement “smart” functions, such as user access control management and energy consumption billing.

[0079] The system may further include embeddable hardware components in which pre-configured identification and configuration information for EV charging devices is set.

[0080] It can be embedded in hardware components and configured for installation in EV charging devices.

[0081] EV charging equipment includes connection components for connecting to a backend system.

[0082] Specifically, the connecting components can be configured and adapted for Wi-Fi connectivity.

[0083] Alternatively, the connection element can be configured and adapted for Ethernet-based connections.

[0084] Alternatively, the connection components can be configured and adapted for 3G / 4G / 5G-based connections. Attached Figure Description

[0087] System 100 includes backend system 10.

[0088] The system 100 further includes an EV charging device 20.

[0096] It can be embedded in hardware components and configured to be suitable for installation in EV charging equipment 20.

[0097] The backend system 10 is characterized by predefined public keys.

[0098] In this embodiment, the backend system 10 includes a storage component 12 for storing defined identification information and configuration information of the EV charging device 20.

[0099] The configuration information of the EV charging device 20, which contains the public key of the backend system 10, is transmitted from the backend system 10 to the EV charging device 20 through the installation channel.

[0100] The installation channel is temporarily established between the EV charging device 20 and the back-end system 10.

[0101] In this embodiment, the installation channel is defined by an installation application running on the user's mobile device (e.g., a smartphone, desktop computer, or the like).

[0102] In this embodiment, the EV charging device 20 is configured by recording the public key of the backend system 10 and the identification information (especially the serial number) of the EV charging device 20.

[0103] A temporary connection can be established between the EV charging device 20 (e.g., including EVSE) and the backend system 10.

[0104] Specifically, a connection between the EV charging device 20 and the backend system 10 can be established via a temporary Internet connection.

[0105] Alternatively, the connection between the EV charging device 20 and the backend system 10 can be via a static Internet connection.

[0106] In this embodiment, the EV charging device 20 includes a connection member 22 for connecting to the backend system 10.

[0107] Specifically, the connecting member 22 can be configured and adapted for Wi-Fi connectivity.

[0108] Alternatively, the connection member 22 may be configured and adapted for Ethernet-based connections.

[0109] Alternatively, the connection member 22 can be configured and adapted for connectivity based on 3G / 4G / 5G standards.

[0110] In one embodiment, the public key of the backend system 10 can be defined based on an X.509 certificate.

[0111] The following describes a method for setting up and installing an EV charging device according to the present invention.

[0112] In this embodiment, the EV charging device 20 includes an EVSE for EV charging, the EVSE having “smart” functions such as user access control management and energy consumption billing.

[0113] In this embodiment, the method includes the following steps: Define the identification information of the EV charging device 20; Define the configuration information of the EV charging device 20; Define the public key for backend system 10; Upload the defined identification information and configuration information of the EV charging device 20 to the EV charging device 20. Before installing the EV charging device 20, upload the defined identification information and configuration information of the EV charging device 20 to the backend system 10; Install 20 EV charging devices on site; Connect the EV charging device 20 to the backend system 10 via the network, and Perform the setup steps for the EV charging device 20, which include transmitting setup information of the EV charging device 20 containing the public key of the backend system 10 from the backend system 10 to the EV charging device 20 via an installation channel.

[0114] The installation channel is temporarily established between the EV charging device 20 and the back-end system 10.

[0115] In this embodiment, the installation channel is defined by an installation application running on the user's mobile device (e.g., a smartphone, tablet, or the like).

[0116] In this embodiment, the setup steps of the EV charging device 20 are implemented by recording the public key of the backend system 10 and the identification information (especially the serial number) of the EV charging device 20.

[0117] In this embodiment, the identification information of the EV charging device 20 includes the serial number of the EV charging device 20.

[0118] On the other hand, the configuration information of the EV charging device 20 may include one or more of the following: The public / private key pair of the EV charging device 20; The public key of the cloud storage component; Name of EV charging device 20; One or more configuration options for the EV charging device 20; The load management settings of the EV charging device 20, and / or One or more safety features of the EV charging device 20.

[0119] Alternatively, the configuration information of the EV charging device 20 may include one or more of the following: Local network configuration parameters; One or more access parameters; Cloud management platform network address; One or more certificates for EV charging equipment 20, and / or One or more OCPP parameters of EV charging device 20.

[0120] Optionally, the public key of backend system 10 can be defined based on an X.509 certificate.

[0121] The identification and configuration information of the EV charging device 20 can be recorded in the manufacturing log file of the EV charging device 20 during manufacturing.

[0122] Alternatively, the method may include providing an embeddable hardware component, into which pre-configured identification information and configuration information of the EV charging device 20 are set.

[0123] The embedded hardware components can then be embedded into the EV charging device 20.

[0124] A temporary connection can be established between the EV charging device 20 and the backend system 10.

[0125] Specifically, a connection between the EV charging device 20 and the backend system 10 can be established via a temporary Internet connection.

[0126] Alternatively, a connection between the EV charging device 20 and the back-end system 10 can be established via a static Internet connection.

[0127] A connection between the EV charging device 20 and the back-end system 10 can be established via Wi-Fi.

[0128] Alternatively, the connection between the EV charging device 20 and the back-end system 10 can be established via an Ethernet-based connection.

[0129] Alternatively, the connection between the EV charging device 20 and the backend system 10 can be established through a connection based on 3G / 4G / 5G standards.

[0130] Optionally, the method may further include defining network-level access data for the EV charging device 20.

[0131] Specifically, network-level access data may include Wi-Fi network names.

[0132] Alternatively, network-level access data may include Wi-Fi network passwords.

[0133] Alternatively, network-level access data may include APN settings.

[0134] By defining the identification and configuration information of the EV charging device and uploading the defined identification and configuration information to both the EV charging device and the backend system before installation, the on-site setup operation of the EV charging device becomes unnecessary.

[0135] Conversely, once the EV charging equipment is installed on-site, it is sufficient to connect the EV charging equipment to the power grid and establish a connection to the back-end system.

[0136] Therefore, EV charging equipment can be set up and installed in a simplified and cost-effective manner without compromising its functionality, especially its "smart" features.

[0137] Figure 3 A block diagram is provided to schematically illustrate exemplary steps in manufacturing, preparing, and configuring an EV charging device according to the present invention.

[0138] EV charging equipment may include one or more EVSEs.

[0139] The EV charging device is provided with a pre-programmed serial number and public / private key pair through a so-called secure element or hardware security chip (e.g., the ATTEC C608A / B microchip).

[0140] EV charging devices contain files with serial numbers and public key pairs that are further stored in the backend system for subsequent use.

[0141] Then, for example, through back-office staff, direct customer input (e.g., online configuration tools), or by implementing on-site planning and configuration steps, an on-site setup plan for the EV charging equipment can be generated.

[0142] The information to be configured varies depending on the specific EV charging device to be configured and / or the available network and / or configuration of the backend system server to be used by the EV charging device.

[0143] Advantageously, the amount of data to be configured can be relatively reduced, including only the EV charging device name, the public key of the backend system, and the configuration parameters of the EV charging device, such as connector locking policy, maximum current, or the like.

[0144] Based on alternative examples, especially when using OCPP, the configuration of EV charging equipment may include the following steps: Define network access information, such as IP configuration, Wi-Fi network access name and key, 4G / 5G SIM APN data or the like; Define the OCPP backend configuration information required for a network suitable for connecting to the OCPP server (e.g., OCPP server base URL, server certificate, charging point identifier, or similar), and Define EV charger device configuration parameters, such as display customization, connector locking strategy, fault-protected charging, current limiting, phase configuration, or the like.

[0145] According to another example, EV charging equipment can have a default configuration and provide a backend system.

[0146] Optionally, in this case, network-level access data (e.g., containing Wi-Fi network name and password and / or APN settings) can be preprogrammed.

[0147] In addition, EV charging devices can be set to automatically search for available networks (e.g., by connecting to an open Wi-Fi network, connecting to an attached Ethernet network using DHCP, or retrieving APN information from a SIM module plugged into the EV charging device).

[0148] Once installed and after physical access to the network medium has been granted, the EV charging device first establishes network-level access to the Internet based on one of the following options: Ethernet obtains IP addresses via Dynamic Host Configuration Protocol (DHCP); Wi-Fi connects to an open network (if available) using a stored network name and password, or connects to a pre-configured Wi-Fi Service Set Identifier (SSID) and then obtains an IP address via DHCP. 2G / 3G / 4G / 5G, using APN settings, using pre-programmed data and / or data provided by the SIM module to connect to the network.

[0149] Next, the connection between the EV charging device and the backend system is established using the stored access information (e.g., network address or hostname) and authentication information (e.g., username / password and / or certificate).

[0150] EV charging devices are characterized by a unique identifier (usually a serial number).

[0151] Once the backend system identifies the EV charging device through its unique identifier, it will transfer the configuration data object to the EV charging device.

[0152] Specifically, this example relies on an auto-configuration concept based on a known / pre-assigned configuration mapping of the EV charging device. Therefore, no field configuration is required, but implementation is limited to the installation site, where unauthenticated network connections or network connections authenticated via physical connections are readily available, such as Ethernet with DHCP or SIM modules with APN information.

[0153] In yet another instance, an EV charging device capable of automatic configuration with centrally configured parameters may further possess additional features to specifically include the data required for alternately forming and / or joining a wireless mesh network.

[0154] In a wireless mesh network, once operational, EV charging devices can form a robust, dynamic, and self-healing relay network, such as containing multiple EVSEs with “smart” capabilities.

[0155] Here, the data necessary for forming the wireless mesh network during manufacturing (e.g., installation code, as in the case of Zigbee® technology used in mesh networks) is pre-installed on the EV charging equipment and, as part of this process, is also transmitted to the back-end system server.

[0156] Next, when configuring the EV charging equipment, the required key is transmitted to the configured EV charging equipment, enabling the mesh network (e.g., a Zigbee®-based mesh network) to be formed in the field without any further action from the operator for this purpose.
