Abstract
Techniques for adaptive power management for non-chiral auxiliary wireless power modules include receiving, by a wireless charging mat, DC input power, determining, dependent on the DC input power, a budget for inductive power available for charging portable devices placed on the wireless charging mat, detecting, at a first port, a connection by a first auxiliary wireless charging mat, determining an amount of power to be provided to the first auxiliary wireless charging mat, determining, dependent on the amount of power to be provided to the first auxiliary wireless charging mat, a reduced budget for the inductive power available for charging portable devices, and providing the determined amount of power to the first auxiliary wireless charging mat. In response to detecting a connection by a second auxiliary charging mat or a portable device at a second port located opposite the first port, the inductive power budget may be further modified.
