Methods and systems for rapid wireless charging where the low state of charge (SOC) temperature dependent charging current and low SOC temperature limit are higher than the high SOC temperature dependent charging current and high SOC temperature limit

A system and method for wireless charging are provided. A control circuit charges one or more cells in a secondary wireless charging circuit that receives power wirelessly from a primary. The control circuit determines the state of charge and temperature of the cells. The control circuit then calculates a current limit as a function of a combination of the state of charge, input voltage to the control circuit for the wireless controller, FET power dissipation and the temperature and adjusts a wireless power control device in the secondary such that its current limit is set to the state of charge current limit. Different temperature limits can be used for different states of charge such that the cells can be charged at higher temperatures at low states of charge than at higher states of charge.
