1. A system for battery management for electric aircraft batteries, the system comprising:
an energy storage system configured to provide energy to the electric aircraft via a power supply connection, the energy storage system comprising:
a battery pack;
a sensor configured to detect a condition parameter of the battery pack and generate a battery datum based on the condition parameter;
a pack monitoring unit (PMU) configured to receive the battery datum, wherein the PMU is further configured to:
identify an operating condition of the battery pack as a function of the battery datum; and
compare the operating condition to a predetermined threshold; and
a high voltage disconnect configured to terminate the power supply connection between the battery pack and the electric aircraft;
wherein the high voltage disconnect is configured to receive an action command generated by the PMU, wherein the PMU creates a lock out flag which is saved in a database of a memory component;
a bus electrically connected to the high voltage disconnect; and
a first controller network bus and a second controller network communicatively connected to the PMU and the primary functional display; wherein the first controller network is configured to electrically isolate from the second controller network.
