Control and diagnostics of power delivery system
A method of monitoring a power delivery system includes receiving a gating signal packet from a power cell or other component of the power delivery system. The received packet includes bits that correspond to the status of one or more devices within the component. The packet also includes one or more bits that contain a subset of stored data that was retrieved from a component memory. Optionally, the method also may include repeating the receiving until multiple gating signal packets are received. The multiple gating signal packets collectively contain the stored data, so that the subsets of the data point may be assembled into the stored data. Optionally, the one or more bits that contain a subset of stored data may be mode bits of the gating signal packet.

delivering a gating signal racket to a component of a power delivery system, wherein the delivered packet includes a plurality of bits that command operation of one or more devices within the component, and wherein the packet includes one or more bits that contain a subset of a command to request a data point including stored data from a component memory; and
receiving a gating signal packet from the component wherein the received packet includes a plurality of bits that correspond to the status of one or more devices within the component, and wherein the packet also includes one or more bits that contain a subset of the stored data that was retrieved from the component memory.
2. The method of claim 1 , further comprising:
repeating the receiving until a plurality of gating signal packets are received, wherein the plurality of received gating signal packets collectively contain the stored data; and
assembling the subsets of the data point into the stored data.
3. The method of claim 1 , further comprising:
repeating the delivering until a plurality of gating signal packets are delivered, wherein the plurality of gating signal packets collectively contain the command; and
assembling the subsets of the command into the command.
4. The method of claim 1 , wherein the stored data comprises fault data.
5. The method of claim 4 , wherein the fault data comprises a fault code.
6. The method of claim 5 , wherein the fault data further comprises a time code or a device identifier.
7. The method of claim 4 , wherein the stored data comprises waveform information.
8. The method of claim 7 , wherein the waveform information comprises current data, temperature data, voltage data or phase data.
9. The method of claim 1 , wherein the one or more bits that contain a subset of stored data are mode bits of the gating signal packet.
10. The method of claim 2 , further comprising using the assembled stored data to determine a component fault diagnosis.
11. The method of claim 2 , wherein the packets also include a plurality of bits corresponding to data that is predictive of failure of a component, and the method also includes delivering a control command to the power cell based on the predictive data.
12. A method of operating a power cell, comprising:
delivering a gating signal packet to the power cell, wherein the delivered packet includes a plurality of bits that command operation of one or more devices within the cell, and wherein the packet includes one or more bits that contain a subset of a command to request a data point including stored data from a cell memory;
receiving a gating signal packet from the power cell, wherein the received packet includes a plurality of bits that correspond to the status of one or more devices within the cell, and wherein the packet also includes one or more bits that contain a subset of stored data that was retrieved from the cell memory;
repeating the receiving until a plurality of gating signal packets are received, wherein the plurality of received gating signal packets collectively contain the stored data; and
assembling the subsets of the data point into the stored data.
13. The method of claim 12 , further comprising, before the receiving:
repeating the delivering until a plurality of gating signal packets are delivered, wherein the plurality of gating signal packets collectively contain the command; and
assembling the subsets of the command into the command.
14. The method of claim 12 , wherein the stored data comprises a fault code and one or both of a time code or a device identifier.
15. The method of claim 12 , wherein the stored data comprises current data, temperature data, voltage data or phase data.
16. The method of claim 12 , further comprising using the assembled stored data to determine a power cell fault diagnosis.
17. A method of monitoring a power cell, comprising:
delivering a gating signal packet to a power cell, wherein the delivered packet includes a plurality of bits that command operation of one or more devices within the cell, and wherein the packet includes one or more bits that contain a subset of a command to request a data point;
repeating the delivering until a plurality of gating signal packets are delivered, wherein the plurality of gating signal packets collectively contain the command;
assembling the subsets of the command into the command;
receiving a gating signal packet from the power cell in response to the command, wherein the received packet includes a plurality of bits that correspond to the status of one or more devices within the cell, and wherein the packet also includes one or more bits that contain a subset of stored data that was retrieved from a cell memory;
repeating the receiving until a plurality of gating signal packets are received, wherein the plurality of received gating signal packets collectively contain the stored data; and
assembling the subsets of the stored data into the stored data.
18. The method of claim 17 , wherein:
the assembled stored data comprises a halt code or waveform data.
