1. A vehicle comprising:
- a body comprising an aircraft fuselage;
a propulsion unit operatively coupled to the body, the propulsion unit comprising an aircraft engine; and
an electrical power system at least partially disposed within the body, the electrical power system including;
a rechargeable battery;
a battery health management unit operatively coupled to the rechargeable battery, the battery health management unit including a state of health module configured to receive battery-related data and to output health information and battery failure information, wherein the battery-related data includes data collected in real time operation of the rechargeable battery and battery relevant fault history of the vehicle;
a battery bus coupled to the rechargeable battery and to the battery health management unit;
at least one AC source operatively coupled to the battery bus;
a recharger coupled to the battery bus;
at least one electrical load coupled to the battery bus; and
an indicator operatively coupled to the battery bus and configured to convey at least a portion of the health information to an operator.
