[0055] Examples of this disclosure relate to techniques for automatically testing the performance of electric vehicle charging interfaces to verify specific safety-related characteristics. For example, the tests may include, but are not limited to, grounding connections (R...). PE Insulation test (R) ISO ); Alternative leakage current test (I) SL ); Contact current test (I) TC ); Load / leakage current test (I PE ( ); RCD performance testing; charging cable integrity testing; PELV (protective extra low voltage) testing; and any additional tests defined by regulatory agencies that are specific to legal vehicle registration requirements.

[0056] Many countries around the world have either already established or proposed regulations for electric vehicles (EVs). These regulations cover various aspects of EVs, including electrical safety, fire safety, manufacturing and quality control, compatibility standards to ensure different EVs can use the same charger, and how EVs can be connected to the power grid. Furthermore, different countries may have their own safety standards and testing procedures.

[0057] An example of a standard EV testing system is a custom rack-mount tool that vehicle manufacturers can use in a factory production environment. This standard tool is specifically designed for testing new vehicles. It may include off-the-shelf components of other testing equipment and software systems that skilled technicians can utilize to perform specific tests without the need for an intelligent user interface to summarize test results.

[0058] With the widespread adoption of EVs, new applications have emerged for testing the electrical safety of vehicle charging interfaces. As more EV safety regulations are introduced, there is a need for portable devices to automate the tests required to verify EV compliance with standards and / or regulations.

[0059] There is a need for innovative and accurate testing methods for electric vehicles. Addressing the technical challenges in testing electric vehicles (EVs) can include the accuracy and precision of test results, enhanced safety of the testing process, speed and efficiency of testing, reliability of test results, test automation, testing complex circuits, non-destructive testing, and understanding of test data.

[0060] According to some embodiments, the test equipment described herein is a complete portable system (e.g., a handheld test device and an ITB) capable of performing various tests based on user requests via a graphical user interface. For example, the system can inject current into an EV for testing purposes. The test equipment can be automated and intelligent, enabling untrained users to perform tests using the device by simply connecting it to the EV charging port and the ITB to another area of ​​the EV. The ITB can be connected to the test equipment via two wires, powering the ITB and connecting analog signals to the test equipment. Digital communication between the ITB and the test equipment can be modulated using the same wires without interfering with the analog signals. Alternatively, the ITB can integrate all or part of its electronics. This may include an analog / digital signal chain, a microcontroller, a display, and other components.

[0061] This disclosure generally describes a system with portable (e.g., handheld) measuring equipment and intelligent test probes (IPBs) capable of performing various electrical safety tests on vehicle charging interfaces. Furthermore, the system can perform tests to verify whether an EV complies with standards and / or regulations. The tests performed can be automatically adjusted by the system based on location.

[0062] The technologies described herein represent innovative aspects of solving technical problems related to electric vehicles. These technologies ensure that test methods and systems deliver accurate and precise results through a user-friendly interface. Furthermore, the test system enhances safety during testing by using test methods and components that comply with safety standards and regulatory requirements. Additionally, these technologies improve the speed and efficiency of testing electric vehicles by reducing test time and resource requirements (e.g., portable measuring equipment). For example, conventional EV testing may require custom rack-mounting tools to test specific EV models, while the claimed invention utilizes a universal portable device capable of testing various EV brands and models. Moreover, the technology improves reliability by providing consistent and repeatable test results. The portable measuring device may also include software that automates testing by integrating it with other processes such as quality control or regulatory compliance.

[0063] Given that electric vehicles (EVs) are highly complex systems, the technology described herein enables automated testing of the complex circuits and systems of EVs without requiring complex user input. Furthermore, the device is capable of performing non-destructive testing of EVs without damaging them. Additionally, the device can analyze and interpret test data and provide results on a graphical user interface.

[0064] For example, a user can use a graphical user interface to request the execution of one test from multiple tests. In response to the user's request, the device can automatically execute the test and present the results on the graphical user interface. The results may include a pass (e.g., a green light) or fail (e.g., a red light) indication. Furthermore, the results may also include a comprehensive report that can be uploaded to the internet via a Wi-Fi connection.

[0065] In some embodiments, the system may perform vehicle-to-grid (V2G) related tests. For example, the system may include a built-in load. In another example, the system may include components for connecting to a mobile load, such as a connector for connecting to a household power outlet.

[0066] To perform various tests, test equipment includes a software layer for communicating with the EV (e.g., performing a handshake). Unlike testing passive devices (e.g., monitors), which do not require communication with passive devices, EV test equipment needs to communicate with the EV to perform different tests. For example, the system may simulate a charging station communicating with the EV and performing tests. This communication may include a handshake to obtain permission to perform certain tests. Furthermore, for some tests, the EV may have to perform an action, which can be transmitted from the test equipment to the EV using the software layer. This action performed by the EV may be entering an electrical state. For example, the EV includes contactors for opening and closing circuits when the EV is ready to charge its battery. In some instances, the test equipment may communicate with the EV to instruct the EV to enter an electrical state associated with charging its battery.

[0067] In addition, the testing equipment may be equipped with a specific vehicle charging inlet connector. Given the existence of different types of EV charging connectors, the equipment may include EV inlet connections that can connect to different types of connectors. In a first embodiment, the equipment may include a Type 1 connector, such as J1772 connector Type 1 or CCS connector Type 1 (CCS1). The J1772 connector is an AC charging standard for North American and Japanese vehicles. The CCS1 connector is a DC charging standard for North American vehicles. In another embodiment, the equipment may include a Type 2 connector, such as Mennekes connector Type 2 or CCS connector Type 2 (CCS2). The Mennekes connector is an AC charging standard for European vehicles. CCS2 is a DC charging standard for European vehicles. In yet another embodiment, the equipment may include a GB / T connector, which is an AC / DC charging standard for Chinese vehicles.

[0068] This disclosure generally describes a portable (e.g., handheld) measuring device capable of performing various electrical safety tests on the vehicle charging interface of an electric vehicle (EV). For example, the device can perform tests to verify whether the EV complies with standards and / or regulations. The tests performed can be automated by the device based on derived information. This derived information may include vehicle information and location information. For example, the device may have a first test protocol for EVs in a first location (e.g., France) and a second test protocol for EVs in a second location (e.g., the United States). The test protocols can be multiple tests determined by the device based on the standards and regulatory compliance requirements of a specific location (e.g., region, country).

[0069] The technologies described herein address technical challenges associated with testing electric vehicles. These technologies ensure that testing methods and equipment provide accurate and precise results. Furthermore, the testing system enhances safety during testing by using testing methods and components that comply with safety standards and regulations. Additionally, these technologies improve the speed and efficiency of testing electric vehicles by reducing testing time and resource requirements associated with portable devices. Moreover, the technology enhances reliability by providing consistent and repeatable test results that can be wirelessly transmitted to third parties. The portable measuring device may also include software that automates testing by integrating it with other processes, such as quality control or regulatory compliance.

[0070] Given that electric vehicles (EVs) are complex systems, some of the example techniques described herein enable the automated testing of complex EV circuits and systems without requiring complex user input. Furthermore, by using a communication process with the EV, the device can perform non-destructive testing (e.g., by performing safety checks before testing), enabling testing of the EV without damaging it. Additionally, the device can analyze and interpret test data and provide results on a graphical user interface.

[0071] As background, many countries around the world have either already established or proposed regulations for electric vehicles (EVs). These regulations cover various aspects of EVs, including electrical safety, fire safety, manufacturing and quality control, compatibility standards to ensure that different EVs can use the same charger, and how EVs can be connected to the power grid. Furthermore, different countries may have their own safety standards and testing procedures.

[0072] In conventional systems, safety testing of general electrical equipment and vehicle-specific safety testing have been practiced for many years. An example of existing general-purpose equipment designed to perform power line safety testing is the Fluke 6500-2 Portable Equipment Tester (PAT). However, with the widespread adoption of EVs, an unresolved need has emerged to perform electrical safety testing on vehicle charging interfaces. As more EV safety regulations are enacted, a portable device is needed to automate the tests required to verify EV compliance with standards and / or regulations.

[0073] Examples of this disclosure relate to techniques for automatically testing the performance of electric vehicle charging interfaces to verify specific safety-related characteristics. For example, the tests may include, but are not limited to, grounding connections (R...). PE Insulation test (R) ISO ); Alternative leakage current test (I) SL ); Contact current test (I) TC ); Load / leakage current test (I PE( ); RCD performance testing; charging cable integrity testing; PELV (protective extra low voltage) testing; and any additional tests defined by regulatory agencies that are specific to legal vehicle registration requirements.

[0074] An example of a standard EV testing system is a custom rack-mount tool that vehicle manufacturers can use in a factory production environment. This standard tool is specifically designed for testing new vehicles. It may include off-the-shelf components of other testing equipment and software systems that skilled technicians can utilize to perform specific tests without the need for an intelligent user interface to summarize test results.

[0075] In contrast, the example test device described herein can be a fully portable device that performs multiple tests based on user requests via a graphical user interface by injecting current into the device under test. This test device can be automated and intelligent, enabling untrained users to perform tests simply by connecting it to an EV charging port. For example, a user can request to perform one of multiple tests using the graphical user interface. In response to the user request, the device can automatically perform the test and present the results on the graphical user interface. The results may include pass (e.g., a green light) or fail (e.g., a red light) indications. Furthermore, the results may include a comprehensive report that can be uploaded to the internet via a Wi-Fi connection.

[0076] To perform different tests, test equipment may include a software layer that communicates with the EV (e.g., performs a handshake). Unlike test passive devices (e.g., monitors) which do not require communication with passive devices, EV test equipment can communicate with the EV to perform different tests. This communication may include a handshake to obtain permission to perform certain tests. Furthermore, for some tests, the EV may have to perform an action that can be transmitted from the test equipment to the EV using the software layer. This action performed by the EV may be entering an electrical state. For example, the EV may include contactors for opening and closing circuits when the EV is ready to charge its battery. In some instances, the test equipment may communicate with the EV to instruct the EV to enter an electrical state associated with charging its battery.

[0077] In some instances, the handshake process includes a physical connection to the EV using an EV connector, establishing communication, safety checks, parameter negotiation, test initiation, continuous communication, and test termination. After the physical connection, both the portable device and the EV can begin communication to identify each other. They exchange information such as vehicle type, device type, user account information, authorization information, vehicle status, vehicle battery status, and other relevant information. Furthermore, before testing, the portable device can perform safety checks (e.g., preventing short circuits, ensuring proper grounding, and eliminating fault conditions) to protect the EV during testing. During testing, test parameters can be exchanged between the portable device and the EV. Additionally, while the vehicle is being tested, the portable device continuously communicates with the EV, providing updates on the test process, adjusting requests as needed, and monitoring for any faults. When the test is complete, the portable device can terminate communication to indicate the end of the test session.

[0078] To perform the handshake, the software layer may include software and firmware integrated into the test system of the portable device. The software layer can be responsible for various functions and features of the portable device, including the handshake with the EV. Furthermore, the software layer can authenticate the portable device with the EV. If user authentication is required for testing, the software layer can manage this user authentication.

[0079] According to some embodiments, the software layer can perform a handshake with the EV to prepare the EV for a test session. For example, after the portable device has been physically connected to the EV, the software layer can send a continuous “pilot signal” (typically a low-voltage square wave) to the vehicle. This pilot signal indicates the device’s readiness and capabilities. Furthermore, the pilot signal provides a channel for the EV and the portable device to transmit and negotiate test parameters. Subsequently, the EV can confirm the connection by modifying the pilot signal in a specific manner (e.g., by changing the signal’s duty cycle). The portable device can receive the modified pilot signal, which notifies the device that the EV is present and ready to be tested. Based on the pilot signal and communication protocol, the portable device and the EV can exchange information about test capabilities and requirements. Once an agreement is reached between the portable device and the EV, the portable device can begin the testing process.

[0080] In addition, the testing equipment may be equipped with a specific vehicle charging inlet connector. Given the existence of different types of EV charging connectors, the equipment may include EV inlet connections that can connect to different types of connectors. In a first embodiment, the equipment may include a Type 1 connector, such as a J1772 connector type 1 or a CCS connector type 1 (CCS1). The J1772 connector is an AC charging standard for North American and Japanese vehicles. The CCS1 connector is a DC charging standard for North American vehicles. In another embodiment, the equipment may include a Type 2 connector, such as a Mennekes connector type 2 or a CCS connector type 2 (CCS2). The Mennekes connector is an AC charging standard for European vehicles. CCS2 is a DC charging standard for European vehicles. In yet another embodiment, the equipment may include a GB / T connector, which is an AC / DC charging standard for Chinese vehicles.

[0135] According to some embodiments, device 110 may be a handheld portable device having an electric vehicle connector 160 configured to be electrically coupled to the charging port of an electric vehicle.

[0136] At 710, device 110 can be connected (e.g., coupled) to the charging port of an electric vehicle using EV connector 160. The connection at 710 allows the device to receive electrical signals from the electric vehicle.

[0142] Figure 8 A flowchart depicts an example method 800 for performing tests on an electric vehicle using a portable device according to an example embodiment of the present disclosure. The portable device (e.g., device 110) may be configured to perform a first test on the electric vehicle. Device 110 may include an EV connector (e.g., EV connector 160) configured to be physically connected to a charging port of the electric vehicle. Furthermore, device 110 may include one or more processors (e.g., processor(s) 230). Additionally, device 110 may include one or more computer-readable media (e.g., memory(s) 232) that collectively store instructions that, when executed by the one or more processors, cause the portable device to perform the operations described in method 800.

[0143] In some instances, method 800 can be executed after method 700.

[0144] At 810, device 110 can use electric vehicle connector 160 to receive electrical signals associated with the first test. The first test may include test parameters. For example, EV test data 240 may be derived from the electrical signals received at 810.

[0145] In some instances, the electrical signal is received after the electric vehicle connector 160 is electrically coupled to the charging port of the electric vehicle. For example, the electric vehicle connector 160 may be a type 1 connector, a type 2 connector, or a GB / T connector.

[0146] In some instances, the first test may be a grounding connection (RPE) test, insulation (RISO) test, alternative leakage current (ISL) test, touch current (ITC) test, leakage current (IPE) test, residual current device (RCD) performance test, charging cable integrity test, or protective extra low voltage (PELV) test.

[0147] In some instances, the initial test may be associated with 480-volt technology. 480-volt charging, compared to 120-volt or 220-volt charging, can be used for fast charging of electric vehicles. Device 110 includes components specifically designed to perform 480-volt technology testing.

[0148] In some instances, test parameters can be determined using machine learning techniques. For example, test parameters can be determined based on the location associated with the device. For instance, a test parameter might have a first value for a first region (e.g., France) and a second value for a second region (e.g., the United States). The first value may differ from the second value. In another example, test parameters can be derived from operational requirements. Operational requirements can be based on the electric vehicle's brand, model, current location, location associated with the electric vehicle's sale, and location associated with the electric vehicle's manufacture. Operational requirements can be based on standards associated with the electric vehicle's manufacturing location. Operational requirements can also be based on regulatory requirements associated with the electric vehicle's sales location.

[0149] At point 820, device 110 can use the electric vehicle connector to transmit a test signal associated with the first test to the charging port of the electric vehicle. In some instances, the test signal may be based on test parameters.

[0150] At 830, device 110 can calculate a measurement value based on the received electrical signal. In some instances, the measurement value calculated at 830 can be determined based on EV test data 240.

[0151] At 840, device 110 can use test parameters to evaluate the measured value to determine the test conclusion of the first test. In some instances, the test conclusion can be a pass or fail conclusion determined based on whether the measured value exceeds the test parameters. For example, when the measured value calculated at 830 exceeds the test parameters of the first test, the test conclusion of the first test can be a fail conclusion.

[0152] At point 850, the device may display test results (e.g., test result 250) based on the test conclusion on a user interface (e.g., user interface 130). For example, the test result may be a green light when the test conclusion is a pass conclusion. Alternatively, the test result may be a red light when the test conclusion is a failure conclusion. In some instances, user interface 130 may be a graphical user interface.

[0153] In addition, the test results 250 may be stored in a non-volatile computer-readable storage medium, such as one or more memory devices 232 or data storage devices 316.

[0154] In addition, device 110 can be a handheld portable device with handle 150.

[0155] In one embodiment, device 110 is powered by a battery. For example... Figure 1 As shown, the battery can be inserted into the handle 150 of the device. The handle 150 can be connected to a cover 155, which can be opened to insert a rechargeable battery. In another embodiment, the device 110 can be electrically connected to a 120-volt, 220-volt, or 480-volt outlet using a connection unit 140.

[0156] In addition, method 800 may also include device 110 transmitting test results 250 to a third-party entity using a wireless connection.

[0157] In some instances, device 110 may include a software layer configured to communicate with an electric vehicle, such as performing a handshake with the electric vehicle. Method 800 may also include device 110 causing the electric vehicle to perform an action after performing a handshake with the electric vehicle. According to one embodiment, this action may be causing the electric vehicle to enter an electrical state associated with charging the battery in the electric vehicle. In some instances, this action may be causing the electric vehicle to close or open circuits in the electric vehicle.

[0158] For example, the software layer enables device 110 to perform a handshake with the EV. A handshake is a communication protocol or process that occurs between the EV and the device before the test process begins. This process ensures that device 110 and the EV are compatible and that the test can be performed safely.

[0159] In some instances, the handshake process includes a physical connection to the EV using EV connector 160, communication establishment, safety checks, parameter negotiation, test initiation, continuous communication, and test termination. After the physical connection, both device 110 and the EV can begin communication to identify each other. They exchange information such as vehicle type, device type, user account information, authorization information, vehicle status, vehicle battery status, and other relevant information. Furthermore, prior to testing, device 110 can perform safety checks (e.g., preventing short circuits, ensuring proper grounding, and eliminating fault conditions) to protect the EV during testing. During testing, test parameters can be exchanged between device 110 and the EV. Additionally, during vehicle testing, device 110 continues to communicate with the EV, providing updates to the test process, adjusting requests as needed, and monitoring for any faults. When the test is complete, device 110 can terminate communication to indicate the end of the test session.

[0160] To perform a handshake from device 110, the software layer may include software and firmware integrated into the test system 220 (e.g., control unit) of device 110. The software layer may be responsible for various functions and features of device 110, including the handshake with the EV. The software layer may support standard communication protocols used in EV charging, such as the Open Charging Point Protocol (OCPP) for charger-to-central system communication, ISO standards, and / or IEC standards. For example, ISO 15118 is designed to handle communication between the EV and the charging station, particularly for more advanced use cases such as plug-and-charge. Furthermore, IEC 61851 is a standard related to conductive charging systems for electric vehicles.

[0161] The software layer can authenticate devices 110 and EV. If testing requires user authentication (e.g., RFID, mobile application, user account), the software layer can manage this authentication.

[0162] According to some embodiments, device 110 uses a software layer to perform a handshake with the EV to prepare the EV for a test session. After device 100 has been physically connected to the EV, the software layer can send a continuous “pilot signal” (typically a low-voltage square wave) to the vehicle. This pilot signal indicates the device’s readiness and capabilities. Furthermore, the pilot signal provides a channel for the EV and device 110 to transmit and negotiate test parameters. Subsequently, the EV can confirm the connection by modifying the pilot signal in a specific manner (e.g., by changing the signal’s duty cycle). Device 110 can receive the modified pilot signal, which notifies the device that the EV is present and ready to be tested. Based on the pilot signal and a communication protocol (such as ISO 15118 or IEC 61851), the EV and device 110 can exchange information about test capabilities and requirements. Once an agreement is reached between device 110 and the EV, device 110 can begin the testing process.
