Bloom Energy had ten patents in batteries during Q3 2023. The first patent is for a power generation system that allows communication between a power source and downstream loads or devices by changing the voltage on a power bus. The power source provides power to the downstream load or device through the power bus.
The second patent is for an electrolyzer system that includes a hotbox, one or more stacks, a fuel exhaust conduit, a fuel exhaust separator, and a recycling conduit. The system separates liquid from the fuel exhaust and connects it back to the fuel inlet conduit.

Application: Power source communication with downstream device by changing output voltage on a power bus (Patent ID: US20230261519A1)
The patent filed by Bloom Energy Corp. describes a power generation system that includes a power source capable of communicating with a downstream load or device by changing the voltage on a power bus. The power source provides power to the load or device through the power bus while adjusting the voltage.
The power generation system mentioned in the patent includes a DC power source with a power source controller and a DC power bus. The downstream device is an inverter containing device with an inverter controller. Importantly, the inverter controller and the power source controller are separate devices, and there is no separate communication link or protocol between them.
The power source controller is designed to determine if an increase in power demand from the load would cause the output power of the power source to exceed a threshold output power. If the threshold output power would be exceeded, the power source controller communicates with the inverter controller by changing the output voltage of the power source instead of increasing the output power. This ensures that the output power no longer tracks the power demand of the load. However, if the output power of the power source would not exceed the threshold output power, the power source controller increases the output power to meet the power demand of the load.
In one embodiment, the load is a microgrid, the device is an uninterruptible power system with an energy storage device, and the power source is a solid oxide fuel cell (SOFC) system.
Overall, the patent describes a power generation system that allows for communication between a power source and a downstream load or device by adjusting the voltage on a power bus. The system includes separate controllers for the power source and the inverter, and the power source controller manages the output power based on the power demand of the load while ensuring it does not exceed a threshold output power.
