The latest data from the Telecommunication Technology Association of Korea (TTA), the WPC’s designated interoperability testing laboratory, shows that the current failure rate for interoperability is around 30%.
Version 1.2.4 of the requirements for Wireless Power Consortium (WPC) certification includes several important points for stakeholders, including the requirements for the Extended Power Profile (EPP) test and Baseline Power Profile (BPP), removing the poorly defined definition for BPP plus Foreign Object Damage (FOD) and adding a requirement that all products with power exceeding 5W must now also meet the requirements in the EPP test.
Failure rates are even higher for EPP, at around 60%. SGS has a robust working relationship with the TTA, which has resulted in the establishment of a TTA pre-interoperability testing laboratory at the SGS facility in Shenzhen. This is currently the only facility on mainland China that is WPC authorized and offers EPP testing services for products up to 15W. The laboratory provides the full range of testing services for electrical and electronic equipment (EEE) manufacturers, including two sets of BPP test equipment and one set of EPP test equipment.
The WPC was founded in 2008 and includes manufacturers of mobile phones, consumer electronics, batteries, semiconductors, components, wireless power technology and infrastructure, such as wireless operators, furniture and automotive parts. Compliance with its standard shows compatibility with global industry standards. It demonstrates a product has reached a specified level of safety, interoperability and energy efficiency and helps mitigate against the risk of overheating, incompatibility with other wireless charging units, and concerns over device damage.
