Application: Electrical power system including energy storage modules and shared system controller (Patent ID: US20240063635A1)

The patent filed by Raytheon Technologies Corp. describes an electrical power system that includes a bus current controller to adjust the DC provided on a DC bus and multiple energy storage modules (ESMs) with DC/DC converters for charging and discharging energy storage devices. The ESMs can be connected in series stacked configurations, with each ESM charging from and discharging onto different rails of the DC bus. The system also includes a shared system controller to manage the bus current controller and DC/DC converters.

The claims of the patent detail the specific configurations and functionalities of the electrical power system, such as independent connections for each DC/DC converter to the DC bus, different types of ESMs with batteries or ultracapacitors, and the use of a rectifier to power DC loads. The method outlined in the patent involves selectively charging and discharging energy storage devices from the DC bus to power DC loads, with the shared system controller playing a key role in managing these operations and controlling the output of the electrical generator. Overall, the patent focuses on optimizing the control and efficiency of an electrical power system for vehicles.
