Distributed low voltage power generation architecture for battery electrified aircraft

An aircraft power distribution system for supplying electrical power to high-voltage propulsion loads and low-voltage system loads, the system comprising:

• a battery pack comprising a first battery and a second battery, wherein the first battery comprises first battery modules and a first direct current to direct current converter, wherein the second battery comprises second battery modules and a second direct current to direct current converter, wherein the first battery modules are electrically connected in series to generate a first battery high-voltage output, wherein the second battery modules are electrically connected in series to generate a second battery high-voltage output, wherein the first battery high-voltage output and the second battery high-voltage output are used to supply power to a set of the high-voltage propulsion loads, wherein the first battery modules are electrically connected in parallel to generate a first battery modules low-voltage output, wherein the first direct current to direct current converter generates a first battery low-voltage output from the first battery modules low-voltage output, wherein the second battery modules are electrically connected in parallel to generate a second battery modules low-voltage output, and wherein the second direct current to direct current converter generates a second battery low-voltage output from the second battery modules low-voltage output;
• a first power distribution unit that distributes the first battery low-voltage output to a first set of the low-voltage system loads;
• and
• a second power distribution unit that distributes the second battery low-voltage output to a second set of the low-voltage system loads.
