Wireless Power Transfer (WPT) technology has been around since the early 1900s (Nikola Tesla), but it has become increasingly more popular within the last decade. Consumer awareness of wireless charging doubled to 76% in 2015, according to IHS Inc. The company predicts that by 2019, wireless charging for wearable technology alone could be worth USD $1-1.2 billion.
Due to this increase in popularity, two consortia are developing industry specification
Independently, the International Electrotechnical Commission (IEC) is developing international standards in two separate WPT Technical Committees (TCs), because of the wide variation in the power demands of various devices and systems ranging from cars to smartphones:
- IEC TC 100/Technical Area (TA) 15: Wireless power transfer of multimedia systems and equipment
- IEC TC 69: Wireless charging of electric vehicles, including industrial trucks, buses, and scooters
An IEC Subcommittee (SC) 21A was also developed to create test and measurement standards for secondary cells and batteries containing alkaline or other non-acid electrolytes used in mobile applications and electric vehicles.
