Reconfigurable control architectures and algorithms for electric vehicle wireless energy transfer systems
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 a first set of essential control functions for the wireless system and isolates the first set of control functions from user modification; and
wherein the secondary controller performs a second set of control functions and exposes the second set of control functions in an access-level hierarchy to user modification through a programming interface.
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 in a common control system.
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 a common physical electronic processor.
10. The system of claim 1 , wherein the primary controller is implemented in a first physical electronic controller and the user configurable secondary controller in a second physical electronic controller different from the first physical electronic controller.
