Abstract
Provided herein is a power distribution system comprising a main power bus, sub-buses coupled to the main power bus, and a controller. The sub-buses provide power to electrical components of a vehicle. Each of the sub-buses includes an electrically programmable fuse in series with a relay. The controller is configured to detect a fault in a sub-bus of the sub-buses, determine a fault type associated with the fault, and in response to determining the fault type, generate a command to cause the relay to change a relay state.
Claims20
A power distribution system comprising:
- a main power bus;
- sub-buses coupled to the main power bus, the sub-buses providing power to electrical components of a vehicle, wherein each of the sub-buses includes an electrically programmable fuse (eFuse) in series with a relay;
- and
- a controller configured to:
- detect a fault in a sub-bus of the sub-buses;
- determine a fault type associated with the fault;
- and
- in response, generate a command to cause the relay to change a relay state.
The power distribution system of claim 14, wherein the one or more fans draw power from a sub-bus of the sub-buses.
A computer-implemented method of operating a power distribution system comprising:
- detecting, by a controller of the power distribution system, a fault in a sub-bus of a plurality of sub-buses based on a telemetry signal received from an electrically programmable fuse (eFuse) associated with the sub-bus, wherein the plurality of sub-buses are coupled to a main power bus of the power distribution system;
- determining, by the controller, a fault type associated with the fault based on the telemetry signal;
- and
- generating, by the controller, a command to cause a relay associated with the sub-bus to change a relay state.
