Overview
NXP®'s wireless charging reference design uses inductive charging technology to charge high-capacity, multi-cell Li-Ion battery packs. The reference design is capable of charging four battery packs simultaneously, using a single NXP digital signal controller. The reference design consists of two main components: a transmitter that sends the requested power level to the battery packs, and a receiver embedded in the battery packs. The receiver provides a controlled charge to the battery by implementing a charging algorithm. Each transmitter channel adjusts its energy transfer independently by responding to commands from the receiver embedded in the battery pack. The intelligent charging method is software-controlled and has the ability to dynamically adjust the power transfer.
