Reconfigurable control architectures and algorithms for electric vehicle wireless energy transfer systems

Abstract

A control architecture for electric vehicle wireless power transmission systems that may be segmented so that certain essential and/or standardized control circuits, programs, algorithms, and the like, are permanent to the system and so that other non-essential and/or augmentable control circuits, programs, algorithms, and the like, may be reconfigurable and/or customizable by a user of the system. The control architecture may be distributed to various components of the wireless power system so that a combination of local or low-level controls operating at relatively high-speed can protect critical functionality of the system while higher-level and relatively lower speed control loops can be used to control other local and system-wide functionality.

1 . A wireless energy transfer system with a segmented control architecture, the system comprising:
 a wireless energy transfer system coupled to a primary controller; and   a user configurable secondary controller in communication with the primary controller;   wherein the primary controller performs essential control functions for the wireless system.   
     
     
         2 . The system of  claim 1 , wherein the essential control functions of the primary controller comprise maintaining wireless energy transfer operating safety limits. 
     
     
         3 . The system of  claim 1 , wherein the essential control functions of the primary controller comprise monitoring and controlling the voltage and current on energy transfer components. 
     
     
         4 . The system of  claim 1 , wherein the user configurable secondary controller allows adjustment of at least one non-safety critical parameter of the system. 
     
     
         5 . The system of  claim 1 , wherein the primary controller and the user configurable secondary controller are each physically implemented on the same hardware. 
     
     
         6 . The system of  claim 4 , wherein the user configurable secondary controller is configurable to adjust a maximum output power of the wireless energy transfer system. 
     
     
         7 . The system of  claim 4 , wherein the user configurable secondary controller is configurable to adjust a frequency of the wireless energy transfer system. 
     
     
         8 . The system of  claim 4 , wherein the user configurable secondary controller is configurable to adjust the security of the wireless energy transfer system. 
     
     
         9 . The system of  claim 1 , wherein the primary controller and the user configurable secondary controller are each virtual controllers implemented on the same processor. 
     
     
         10 . The system of  claim 1 , wherein the primary controller and the user configurable secondary controller are each separate processors.
