Renesas, one of the largest manufacturers of microcontroller based wireless power solutions, have released a Qi v1.3 certified customer reference design for use in in-cabin automotive inductive chargers. This reference design is capable of supporting the Wireless Power Consortium’s Extended Power Profile (EPP) for charging speeds of up to 15W and proprietary charging profiles of up to 50W charging speeds.
Renesas (plus acquired IDT) have long been a key player in the wireless power market, and it is likely that elements of this design will find their way into many different Qi v1.3 wireless chargers going forwards. SAR Insight & Consulting provide a wireless charger forecast by different power profiles and versions of the Qi specification in its recently published Wireless Power and Charging Technologies report.
