Energy management system for a vehicle
First Claim
1. An energy management system for a vehicle having at least one energy storage device, the system comprising:
- a connection element adapted to connect to a first terminal of the energy storage device;
a terminal body having a terminal connection point configured to connect to a second terminal of the energy storage device;
at least one electrical shunt coupled to the terminal body and the connection element, the electrical shunt providing a path for the flow of current from the terminal connection point to the connection element;
an electrical circuit coupled to the shunt, the electrical circuit being configured to determine predetermined parameters of the energy storage device based on the flow of current through the electrical shunt; and
wherein the at least one shunt includes at least two shunts configured to have substantially the same electrical resistance.

Abstract
An energy management system and method for a vehicle monitors the state and/or condition of at least one energy storage device. A connection element is included that is adapted to connect to a first terminal of the energy storage device. A terminal body is included having a terminal connection point configured to connect to a second terminal of the energy storage device. At least one electrical shunt is also coupled to the terminal body and the connection element wherein the electrical shunt provides a path for the flow of current from the terminal connection point to the connection element. This system further includes an electrical circuit coupled to the shunt that is configured to determine predetermined parameters of the energy storage device based on the flow of current through the electrical shunt.

9. A monitoring system for determining a parameter of an energy storage device used to provide power to one or more loads, the system comprising:
-
an electrically conducting terminal body having a fastening element configured to connect to a terminal of the energy storage device; a shunt device having two separate, vertical shunts commonly terminating at a body portion, the two shunts being electrically connected to the terminal body and the body portion being electrically isolated from the terminal; a connection element fastened directly to the body portion and in electrical communication with the one or more loads such that current flows from the terminal to the one or more loads by travelling through the terminal body and then through the two shunts and then through the body portion and finally through the connection element; and an electrical circuit coupled to the shunt, the electrical circuit being configured to determine predetermined the parameter of the energy storage device based on the flow of current through the electrical shunt. - View Dependent Claims (10)

11. An energy management system for a vehicle having an energy source configured to distributed electrical energy to a load, the system comprising:
-
a shunt having a unitary, U-shaped structure with two, separate blades at a first end that commonly terminate at an opposite, second end; a terminal connected to the energy source and shaped to support both of the first and second ends of the shunt; an insulator between the terminal and the second end of the shunt, the insulator being shaped to electrically isolate the second end of the shunt from the terminal; a bracket connected to the second end of the shunt, the bracket completing a current path between the energy source and the load, the current path limiting current flow between the energy source and load such that current originating from the energy source must sequentially flow through the terminal, through both blades included at the first end of the shunt, through the second end of the shunt, and finally through the bracket before reaching the load; and a circuit supported by the terminal configured to measure a voltage drop across both the blades in order to parameters of the energy storage device as a function of current flow through the shunt. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19)
