QI EXTENDED POWER PROFILE RECEIVER

Use Cases


This solution will typically be used in the following contexts :
  • certification of power receivers towards the specifications edited by the WPC (Wireless Power Consortium)
  • pre-certification at vendor R&D labs of power receivers
This solution allows to test the compliance of a contactless power receiver (for example a mobile phone). It will be tested following the recommendations defined by the WPC (Wireless Power Consortium). Here we will test the Extended Power Profile (EPP) variante. The WPC (Wireless Power Consortium) defines a framework of test procedures. It aims at verifying the global interoperability of power transmitters with power receivers. Even though our offering covers both receiver and transmitter testing, in both BPP and EPP variantes, this solution here focuses on receiver testing, in the EPP mode. This solution is based on the MP500 TCL3 tester, and the dedicated Wireless Power Consortium accessory kit. Therefore, the Micropross solution has the unique asset of enabling both Wireless Charging, but also NFC testing, based on the same hardware. Following at 100% the requirements defined in the 'System Description Wireless Power Transfer Volume II: EPP Part 3: Compliance Testing', the main characteristics of this solution are :
  • one compact test tool, embedding all necessary generation and measurement features
  • availability of all normative accessories (TPR, TPT, Foreign objects, Thermo couple, …)
  • fully automated operation mode, for less mistakes in the measurement
  • automated generation of test reports
  • easy migration to Basline Power Profile testing, as well as transmitter testing

Technical data

The test system is made of the following items :

The MPManager test platform takes control of the MP500 TCL3, and performs test sessions according to the requirements of the WPC. Physical measurement are done automatically by the MP500 TCL3, and the test platform gives a clear verdict, and displays the reason why a test case passes, or fails.

The coverage of the EPP tests inclides:

  • load modulation amplitude
  • frequency demodulation
  • selection and ping phase
  • The Samsung specific test cases
  • Authentification
