Abstract
A method for monitoring an electric vertical takeoff and landing vehicle (eVTOL) includes receiving current and voltage signals indicative of electric power supplied to an electric load of the eVTOL and identifying an event associated with the electric load or with a component associated with the electric load based on the current and voltage signals. The method also includes determining a change in a condition of the electric load or of the component connected to the electric load based on the identified event and outputting a notification based on the change in the condition of the electric load or with the component connected to the electric load.
Claims20
A method for monitoring an electric vertical takeoff and landing vehicle (eVTOL), the method comprising:
- receiving current and voltage signals indicative of electric power supplied to an electric load of the eVTOL and including determining an active power level and a reactive power level, based on the current and voltage signals;
- identifying an event associated with the electric load or with a component associated with the electric load based on (i) the current and voltage signals and (ii) comparing the active power level to a threshold or the reactive power level to a threshold;
- determining a change in a condition of the electric load or of the component connected to the electric load based on the identified event;
- and
- outputting a notification based on the change in the condition of the electric load or with the component connected to the electric load.
A monitoring system for an electric vertical takeoff and landing vehicle (eVTOL), the system comprising:
- a memory storing instructions;
- and
- one or more processors that, when executing the instructions, perform operations including:
- receiving signals indicative of electric power supplied to an electric motor operatively connected to a propeller of the eVTOL, including determining an active power level and a reactive power level, based on the signals;
- identifying an event associated with the electric motor or with a component associated with the electric motor based on (i) the received signals and (ii) comparing the active power level to a threshold or the reactive power level to a threshold;
- and
- outputting a notification based on the identified event, the notification indicating one or more of:
- component failure, component wear, component remaining useful life, or a need to perform maintenance, for the electric motor or the component associated with the electric motor.
A method for monitoring an electric vertical takeoff and landing vehicle (eVTOL), the method comprising:

- identifying an event based on (i) the current and voltage signals and (ii) comparing the active power level to a threshold or the reactive power level to a threshold;
- identifying a component associated with the event based on the current and voltage signals;
- determining a change in a condition of the component based on the identified event;
- and
- monitoring changes in the condition of the component over time.
