Qi compatible wireless charging (up to 100W)

In wireless battery charging and wireless power transfer systems, power is transferred by electromagnetic induction between a transmitting pad or dongle (Tx) and the receiver device (Rx), such as a smartphone, smartwatch, robot cleaner, and other industrial tools. The Qi standard from the Wireless Power Consortium (WPC) is one of the most popular standards for mobile, wearable, and other applications. The Qi standard provides fully interoperable power profiles for 5 W up to 15 W. There are multiple proprietary extensions by manufacturers that support up to 50 W and even 100 W.

Key challenges

  • Achieving high power levels and efficiency comparable to wired power transfer.
  • Consistency in different device orientations and in the presence of foreign objects.
  • Human safety and protection from damage to nearby objects.
  • High interoperability between various Tx and Rx products.
  • Compact and cost-effective designs with fast time-to-market.
