  • Method and system for testing electric automotive drive systems
    Patent number: 8310272
    Abstract: Various methods and systems for testing electric automotive drive systems are provided. The methods may be implemented with components with components that are used during normal operation of the automobile, such an inverter, an electric motor, and an electronic control system. One such method includes adjusting the frequency of a current pulsed input provided to an electric motor while monitoring the winding currents. Another method includes monitoring current flow during and after a direct current (DC) pulse is generated by switches within an inverter. A further method includes monitoring current flow while a deactivation signal is provided to the switches and during individual activation of the switches.
