Abstract: A method for controlling a current flow through a power distribution circuit includes determining a current flow through a load electrically connected with the power distribution circuit, and a wire gauge of the power distribution circuit based on a measured output current and output voltage of the power distribution circuit. The method also includes controlling the output current based on the current flow through the load and the wire gauge.

Abstract: The invention is a doped synthetic polymer material for packaging of power electric assemblies. The polymer provides electromagnetic interference (EMI) shielding using such materials as nickel, carbon fiber, aluminum or other such characteristic elements. The invention provides structural integrity for power electronic packaging, while reducing cost, size, weight and design flexibility over the prior art.

Abstract: A distributed battery control network (14) for a battery string (12) has a plurality of sensing modules (SM) each associated with one of the batteries in the battery string (12). Each of the sensing modules has a respective sequencing input (SI) and a sequencing output (50). Said plurality modules have a sequencing input with a predetermined signature type, storing said address in a particular one of said plurality modules with said sequencing input equal to said signature type, and generating an identifying signature at an output of said particular one of plurality modules with said sequencing input equal to said signature type. A network (22) is coupled to each of the sending modules. A controller (24) is coupled to the bus and communicates with each of the sensing modules. The controller (24) loads each of the sensing modules with an address and a signature type.

Abstract: In one embodiment of the present invention, a system is provided or measuring the voltages of the traction batteries of an electric vehicle. The system includes switches provided to switchably couple the batteries individually to an amplifier. The system also includes switches provided to assure that the same polarity is always provided to the amplifier; a single-ended amplifier can thus be used. The system includes an analog-to-digital converter coupled in communication with the output of the amplifier, and an optical coupler which couples the output of the analog-to-digital converter to the low-voltage portion of the electric vehicle's electrical system.
