Chroma WPT test solution performs interoperability, performance, and radiation emission testing of wireless inductive charging systems. Chroma provides WPT test solutions for all power classifications ranging from 3.7kVA to 22kVA. Simply adjust the parameters to test a variety of conditions with the easy-to-use WPT software.
▲ WPT ATS Components
Chroma WPT ATS tests comply with the SAE J2954 regulation. The modular design can easily upgrade to also meet upcoming regulations such as IEC 61980. Chroma WPT ATS is equipped with various automatic and semi-automatic fixtures on six axes for GA and VA placement with greater accuracy.

EV WPT Test Platform
 |
A major benefit of wireless charging is the flexibility provided in alignment between the charging infrastructure and the vehicle. Vehicles can charge even without proper alignment, but to increase the efficiency and safety, some level of alignment is required. Chroma includes a XYZ-positioning fixture to accurately test the efficiency of the GA and VA at a variety of positions and heights. |
|
Chroma offers different solutions for different stages of testing, such as prototyping or EV testing. An automatic positioning device with multi-axes rotation enables yaw, roll, and pitch testing. Chroma’s patented center alignment jigs use a laser that places the GA and VA in the center to test with maximum efficiency. |

WPT FOD Test Fixture
 |
Since WPT uses radiation for charging, if there is any metallic object in between the charger facility and vehicle, the temperature could rise while charging which may lead to a hazardous situation. For safety precautions, the charger should not energize if it detects any foreign objects in between the GA and VA. To test above condition, Chroma offers a FOD test fixture to place the object at different positions and verify the charger’s behavior. These positons are documented so that the test results can be recreated. |

WPT Power Test Software
Chroma’s software lets users adjust the parameters of the source/load equipment and positioning table for efficient testing. During the test, the interface displays test data and 2D/3D graphs in real time. After completion, it auto generates the test report and includes data and graphs for easy analysis.
