US Patent:

20180026463, Jan 25, 2018

Filed:

Jul 21, 2016

Appl. No.:

15/216149

Inventors:

- Detroit MI, US
KENNETH L. KAYE - ROCHESTER HILLS MI, US

International Classification:

H02J 7/00
H01M 8/04992
H02M 3/156
H01M 8/04828

Abstract:

A fuel cell charging system includes a fuel cell stack having a first operating direct current (DC) voltage between fuel check stack terminals, a high voltage system operating at a first DC operating voltage different than and generally higher than the first operating voltage of the fuel cell stack, a boost converter in electrical connection with the fuel cell stack and the high voltage system, and a stack charging component that applies a second DC operating voltage, generally of lower value than that of the first normal operating voltage, to the fuel cell stack. The boost converter transfer electrical power from the fuel cell stack to the high voltage system during fuel cell operation. Characteristically, the second DC operating voltage applied to the fuel cell stack terminals is typically lower in value than that of the first DC operating voltage of both the fuel cell stack and the HV electrical system and is stepped down from the first DC operating voltage of the HV electrical system.

Abstract:

Methods and systems for identification of slave elements and/or cells in a communication system within a vehicle. In some implementations, such methods may comprise measuring a first voltage of a first slave device of a plurality of slave devices within the communication system, and measuring a second voltage of a second slave device of the plurality of slave devices within the communication system. A location of at least the first and second slave devices, which may be linked with respective cells, such as battery cells or fuel cells, may then be identified by comparing at least the first voltage with the second voltage.
