Assignee:
GM Global Technology Operations, Inc. - Detroit MI
International Classification:
H01H 47/00
US Classification:
307130
Abstract:
A connection monitoring system and method for a vehicle high voltage energy storage system is disclosed. The method performs a check, at initial connection of the high voltage energy storage system, to insure that the vehicle high voltage wiring system is fully connected and without short circuits prior to allowing full current to the vehicle and normal vehicle operation. The method switches in a resistor to limit current flow between the high voltage energy storage system and the vehicle high voltage wiring, and measures the voltage and a voltage rise time across the resistor. The voltage and the voltage rise time across the resistor are used to determine if a short circuit is present, and if so the high voltage energy storage system is disconnected to protect the vehicle and its users.

Assignee:
GM Global Technology Operations, Inc. - Detroit MI
International Classification:
G01R 31/02
G06F 19/00
G06F 19/00
US Classification:
701 22, 701 1, 701 29, 318479, 180 6523
Abstract:
A method is provided for predicting a loss of high-voltage isolation within a hybrid, electric, or fuel cell vehicle. The method includes recording the equivalent resistance between a vehicle chassis and a high-voltage bus, detecting a trend in the measurements, and predicting when the resistance will drop below a threshold value. The method also includes issuing a warning or message to the owner/operator when the predicted remaining number of events drops below a predetermined number and/or when the resistance drops below the threshold. Additionally, an apparatus is provided for predicting a high-voltage isolation fault comprising a controller having an algorithm for predicting the fault, a high-voltage bus and bus components, and a reporting device for reporting the fault and/or predetermined number of remaining events. The controller is configured to initiate the algorithm and record a series of equivalent resistance measurements taken between the vehicle chassis and high-voltage bus.
Simplified Automatic Discharge Function For Vehicles

7768237, Aug 3, 2010
Filed:
May 11, 2007
Appl. No.:
11/747379
Inventors:
James E. Tarchinski - Rochester Hills MI, US
Assignee:
GM Global Technology Operations, Inc. - Detroit MI
International Classification:
H02J 7/00
H02P 9/04
H02P 9/04
US Classification:
320135, 320167, 290 40 C
Abstract:
Methods and system are disclosed for an automatic discharge function for a vehicle having an electric or hybrid electric motor. The methods and system monitor the motor for occurrence of a power shutdown. If the power shutdown occurs, a contactor pair is opened, and immediate discharging of capacitance is initiated in response to opening the contactors pair. Discharging is continued until the capacitance is completely discharged.
High-Voltage Vehicle Component Connection Method And Apparatus
View pageUS Patent:
7786386, Aug 31, 2010
Filed:
Apr 15, 2008
Appl. No.:
12/102921
Inventors:
James E. Tarchinski - Rochester Hills MI, US
Assignee:
GM Global Technology Operations, Inc. - Detroit MI
International Classification:
H01B 12/00
US Classification:
1741251
Abstract:
A method and apparatus provide an electrical splice between different high-voltage components in a high-voltage propelled vehicle (HVPV), which enables a daisy-chain or series connection of the components. The method includes connecting a first end of a cable to a first component, a second end of the cable to a high-voltage bus bar within a second component to form a splice, and using the outer housings of the components to provide an environmental seal and electromagnetic capability (EMC) shield for the splice, rather than providing such a splice within a dedicated or shared power distribution box. A ring terminal connects to an end of a cable by a press-fitting process or a soldering process. The components can be an energy storage system (ESS), a power inverter module (PIM), an air conditioning control module (ACCM), an auxiliary power module (APM), a power steering controller, and an electrical motor/generator.
High Voltage Connector And Method Having Integrated Voltage Measurement Probe Points
View pageUS Patent:
7906957, Mar 15, 2011
Filed:
Nov 20, 2008
Appl. No.:
12/274384
Inventors:
James E. Tarchinski - Rochester Hills MI, US
Joseph Ciagala - Shelby Township MI, US
Joseph Ciagala - Shelby Township MI, US
Assignee:
GM Global Technology Operations LLC - Detroit MI
International Classification:
G01R 1/06
US Classification:
324149, 324538
Abstract:
An electrical connector adapted for staged disassembly to test for high voltage includes a plug having an enclosed electrical terminal with a first opening exposing the terminal and a socket having another enclosed electrical terminal with an opening exposing the other terminal. The socket opening is substantially complementary to the first opening to receive the plug sufficiently into the socket to electrically engage the terminals in first and second positions. A port in one of the socket or plug provides access to one of the terminals in one of the positions but is obstructed from access to a terminal in the other of the positions. The port is small enough to prevent a finger from accessing a terminal but large enough to receive an electrical meter probe for voltage testing. A latch on the box portions positions the port in each of the two positions.
High-Voltage Vehicle Fault Detection Method And Apparatus

7966110, Jun 21, 2011
Filed:
Mar 5, 2008
Appl. No.:
12/042418
Inventors:
James E. Tarchinski - Rochester Hills MI, US
Assignee:
GM Global Technology Operations LLC - Detroit MI
International Classification:
G06F 7/00
G05B 23/02
G05B 23/02
US Classification:
701 29, 701 22, 903907, 318479
Abstract:
A method includes detecting high-voltage faults, such as welded contactors or disconnected components, in a vehicle by measuring the total electrical impedance between positive and negative rails of a high-voltage bus and a ground or chassis, comparing the impedance before and after opening the contactors, and executing a maintenance response. The response includes setting an error code when the open impedance level is less than a threshold multiple of the closed impedance level. A vehicle includes a chassis, energy storage system (ESS), motor/generator, and a high-voltage bus conducting electrical current from the ESS to the motor/generator. Contactors are positioned along each of the rails of the bus, a device for measuring a total electrical impedance level between the chassis and each of the rails, and a controller for determining a welded contactor condition of at least one of the contactors based on the measured total electrical impedance level.

The series interlock loop has an overall electrical characteristic. The series interlock loop includes first and second safety interlocks electrically coupled in series. Each interlock includes a switch coupled in parallel with an impedance value. The data table is configured to store values corresponding to the impedance values. The control module is communicatively coupled to the data table and configured to receive an indication of the overall electrical characteristic and to compare the overall electrical characteristic to the values in the data table to thereby identify an open one of the first and second safety interlocks.
