GB T 33594 Wireless Power Transfer Charging Test
The GB/T 33594 standard specifies a method for testing wireless power transfer (WPT) systems in electric vehicle charging applications. This test is essential to ensure that the WPT system meets safety, efficiency, and performance requirements as outlined by the Chinese national standard.
Wireless Power Transfer (WPT) technology enables the transfer of electrical energy between a charging pad and an electric vehicle without physical contact. The GB/T 33594 test encompasses various aspects to validate the functionality and reliability of these systems, such as power transmission efficiency, electromagnetic compatibility (EMC), safety features, and interoperability.
The testing process involves multiple stages to ensure thorough evaluation of the WPT system's performance. Initially, the charging pad is connected to a dedicated power supply, which simulates an electric vehicle's onboard charger. The test setup includes a receiver coil embedded in a mock-up vehicle, representing the receiving end of the wireless power transfer.
The first stage of testing focuses on establishing a stable and efficient power transmission between the charging pad and the mock-up vehicle. This involves measuring the voltage, current, and power delivered by the system at different operating conditions. The efficiency is calculated based on these measurements to ensure that the system operates within specified limits.
During the second stage, the electromagnetic compatibility (EMC) of the WPT system is evaluated. This includes tests for emissions and immunity in accordance with relevant international standards such as IEC 61000-4-2, -4-3, and -4-8. EMC testing ensures that the WPT system does not interfere with other electronic devices and can withstand external electromagnetic interference.
The third stage of the test assesses the safety features of the WPT system. This includes evaluating the protection mechanisms against overcurrent, overheating, and short circuits. The tests are conducted in accordance with GB/T 18495, which specifies the technical requirements for electric vehicle charging systems.
Lastly, interoperability testing is performed to ensure that the WPT system can work seamlessly with different types of vehicles and charging stations. This involves connecting the mock-up vehicle to various charging pads from different manufacturers and verifying that data communication between the two ends functions correctly.
The results of each test are meticulously recorded and analyzed. The report includes detailed information on the measured parameters, such as efficiency, emissions, immunity levels, protection mechanisms, and interoperability performance. This comprehensive documentation serves as a benchmark for the quality and reliability of the WPT system.
