Vehicle monitoring system

A method comprising:

• measuring one or more parameters of operation of one or more propulsion systems of a vehicle system;
• identifying one or more high-stress events of the one or more propulsion systems based on the one or more parameters that are measured;
• calculating a cumulative usage of a component of the one or more propulsion systems based on the one or more high-stress events that are identified;
• and
• predicting an end of life date of the component of the one or more propulsion systems based on the cumulative usage that is calculated,
• wherein the high-stress event is associated with one or more of:
• an operating speed, a temperature, or a throttle setting of the propulsion system;
• a supplied voltage, a supplied current, a current balance, or an internal resistance of a battery system of the vehicle system;
• or
• operation of a cooling fan of the vehicle system, or an ambient atmosphere surrounding the vehicle system for cooling.

A system comprising:

• a controller configured to identify one or more high-stress events of a propulsion system of a vehicle system based on one or more parameters that are measured by a sensor, the controller configured to calculate a cumulative usage of the propulsion system based on the one or more high-stress events that are identified, and the controller is configured to predict an end of life date of a component of the propulsion system based on the cumulative usage that is calculated and to automatically change one or more planned operational settings for a current trip or upcoming trip of the vehicle system based on the end of life date that is predicted,
• wherein the high-stress event is associated with one or more of:
• an operating speed, a temperature, or a throttle setting of the propulsion system;
• a supplied voltage, a supplied current, a current balance, or an internal resistance of a battery system of the vehicle system;
• or
• operation of a cooling fan of the vehicle system, or an ambient atmosphere surrounding the vehicle system for cooling.
