US 10,704,818 B2 · Method and system for dynamic power allocation in a transport refrigeration system

Abstract

A method and system for dynamic power allocation in a transport refrigeration system (TRS) is provided. The method includes a TRS power source operating in an operational state. The method also includes monitoring an amount of current being drawn from one or more generator powered components of the TRS. Also, the method includes calculating, via a TRS controller of the TRS, a maximum available horsepower amount based on the amount of current being drawn from the one or more generator powered components. Further, the method includes controlling, via the TRS controller, an amount of horsepower directed to a compressor of the TRS based on the maximum available horsepower amount.

Dependent claims

A method for dynamic power allocation in a transport refrigeration system (TRS), the method comprising:

monitoring an amount of current being drawn by one or more loads of the TRS, wherein the one or more loads include one or more of a fuel heater, a transport refrigeration unit battery, a solenoid valve, a drain tube heater, or an accessory load;
determining a load power draw based on the amount of current being drawn by the one or more loads of the TRS;
determining a maximum available power amount based on the amount of current being drawn by the one or more loads;
and
dynamically controlling, via a controller, an amount of power directed to the compressor of the TRS to continuously allocate the maximum available power amount to the compressor of the TRS.
