First Claim
Patent Images
1. A method for controlling a power transfer rate in to and/or out of a vehicle energy storage device, during a power transfer opportunity, the method comprising:
- adjusting the power transfer rate based on a predetermination of a duration of the power transfer opportunity to match a duration of power transfer to the duration of the opportunity and achieve a specified state of charge.

Abstract
Systems and methods are described for controlling a power transfer rate in to and/or out of an energy storage device on-board a vehicle, such as a locomotive, during a power transfer opportunity. In one example, the method includes adjusting the power transfer rate based on a predetermination of a duration of the power transfer opportunity to match a duration of power transfer to the duration of the opportunity and achieve a specified state of charge.

15. A system for a locomotive, comprising:
-
an energy storage device; and a control system configured to, during a power transfer opportunity, predetermine a duration of the power transfer opportunity based on information of the power transfer opportunity, and adjust the power transfer rate of the device based on the predetermined duration to thereby adjust an actual duration of power transfer for achieving a specified state of charge. - View Dependent Claims (16)

17. A system for a locomotive, comprising:
-
an energy storage device; and a control system configured to, during a first power transfer opportunity with a first predetermined duration of the power transfer opportunity, where the energy storage device is at a first age and a first temperature, transfer power in to and/or out of the energy storage device with a first power transfer rate for a first duration of power transfer, said first power transfer rate having a first upper and a first lower threshold for a desired state of charge, to substantially fill the first predetermined duration of the power transfer opportunity; during a second power transfer opportunity with a second predetermined duration of the power transfer opportunity, said second predetermined duration being larger than said first predetermined duration, where the energy storage device is at the first age and the first temperature, transfer power in to and/or out of the energy storage device with a second power transfer rate for a second duration of power transfer, said second power transfer rate being smaller than said first power transfer rate, said second duration of power transfer being larger than said first duration of power transfer, to substantially fill the second predetermined duration of the power transfer opportunity; and during a third power transfer opportunity, with a third predetermined duration of the power transfer opportunity, said third predetermined duration being smaller than said first predetermined duration, where the energy storage device is at the first age and the first temperature, transfer power in to and/or out of the energy storage device with a third power transfer rate for a third duration of power transfer, said third power transfer rate being larger than said first power transfer rate, said third duration of power transfer being smaller than said first duration of power transfer, to substantially fill the third predetermined duration of the power transfer opportunity. - View Dependent Claims (18)

19. A method of controlling a power transfer rate in to and/or out of an energy storage device in a powered system, during a power transfer opportunity, the method comprising:
-
operating the powered system according to a schedule, wherein the schedule includes data about a duration of the opportunity to generate electrical power in the powered system; and adjusting a power transfer rate of electrical energy in to or out of the energy storage device, based on the data to match a duration of power transfer to the duration of the opportunity and achieve a specified state of charge. - View Dependent Claims (20)
