METHODS AND SYSTEMS FOR PRESERVING THE LIFE OF A TRANSPORT REFRIGERATION SYSTEM POWER SOURCE
First Claim
1. A method for preserving the life of a transport refrigeration system power source comprising:
- determining whether a control unit of the transport refrigeration system is off;
measuring an input voltage of the transport refrigeration system power source when the control unit is off;
instructing, via the network coordinator, one or more parasitic electronic devices of the transport refrigeration system to operate in a hibernation mode when the input voltage of the transport refrigeration system power source remains below a voltage threshold value for a time period and the control unit is off.

Abstract
Methods and systems for preserving the life of a transport refrigeration system power source are provided. The method can include determining whether a control unit of the transport refrigeration system is off. Also, the method can include measuring an input voltage of a network coordinator when the control unit is off. Further the method can include instructing one or more parasitic electronic devices of the transport refrigeration mode to operate in a hibernation mode when the input voltage of the transport refrigeration system power source remains below a voltage threshold value for a time period and the control unit is off.

9. A transport refrigeration system comprising:
-
a transport refrigeration system control unit; an engine connected to the control unit; a transport refrigeration system power source connected to the transport refrigeration system control unit and the engine; a network coordinator connected to the transport refrigeration system control unit; and one or more parasitic electronic devices that are connected to the transport refrigeration system control unit and the transport refrigeration system power source, the one or more parasitic electronic devices configured to draw current from the transport refrigeration system power source when the transport refrigeration system control unit is off, wherein the network coordinator is configured to instruct the one or more parasitic electronic devices to operate in a hibernation mode when the transport refrigeration system control unit is off and an input voltage of the transport refrigeration system power source remains below a voltage threshold for a time period. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)
