US Patent:

20080042615, Feb 21, 2008

Filed:

Jul 24, 2006

Appl. No.:

11/459380

Inventors:

Richard K. Serrels - Otisville MI, US
Gretchen Serrels - Otisville MI, US
William J. Omell - Washington Township MI, US
Richard M. Breese - Los Angeles CA, US

International Classification:

H02J 7/00

US Classification:

320101

Abstract:

A fuel economy control method for a hybrid vehicle includes estimating a temperature of a battery, measuring a current of the battery, and measuring a voltage of the battery. A nominal optimum charging voltage is determined as a function of a state of charge (SOC) of the battery and the estimated temperature. The nominal optimum charging voltage is reduced to a fuel economy minimum charging voltage if the SOC is above a predetermined level and the current is within a predetermined range. The battery is then charged at the fuel economy minimum charging voltage using a DC/DC converter.

International Classification:

G01R 19/00

US Classification:

324 7611

Abstract:

Methods and apparatus are provided for monitoring a coolant conductivity of a fuel cell supplying power via positive and negative buses. The method includes measuring a first voltage of the positive bus, measuring a second voltage of the negative bus, applying a resistance between the positive bus and a reference potential, measuring a third voltage of the positive bus after a period of applying the resistance, and determining an isolation resistance based on the measured voltages. The isolation resistance is a function of the coolant conductivity.

International Classification:

B60L 3/00
B60L 15/04
B60L 15/20

Abstract:

An illustrative dual power inverter module includes a detection circuit configured to detect loss of low voltage DC electrical power supplied to a controller for a first power inverter and a second power inverter of a drive unit for an electric vehicle. A first backup power circuit is associated with the first power inverter and a second backup power circuit is associated with the second power inverter. Each backup power circuit is configured to convert high voltage DC electrical power to low voltage DC electrical power responsive to detection of loss of low voltage DC electrical power supplied to the controller. Three-phase short circuitry is configured to apply a same fault action to the first power inverter and the second power inverter responsive to detection of loss of low voltage DC electrical power supplied to the controller, wherein the same fault action includes applying equalized torque to each axle operatively coupled to the drive unit.

International Classification:

G01R 15/20
G01R 31/40
G01R 19/00

Abstract:

A three-phase current sensor for measuring currents running in three conductors of a three-phase conductor system includes at least a first magnetic measuring device. The magnetic measuring device includes a magnetic circuit provided with at least two gaps and a magnetic field sensor arranged in each gap of the magnetic circuit. The magnetic field sensors are positioned on both sides of a cavity sized to receive one of the three conductors. The gaps and thus the magnetic field sensors are positioned such that stray magnetic flux from an adjacent conductor has substantially equal amplitude passing through each of the sensors.
