Patent Number Title Of Patent Date Issued
8164433 Detecting faults in a wiring harness April 24, 2012
Cell voltages within a battery pack and a voltage delivered to a load or drive system, along with a current delivered to the system, are monitored and used to detect a possible abnormal condition of a wiring harness.
7782014 System and method for battery management August 24, 2010
A method and system for managing a plurality of batteries and useable by way of example with a partially or completely electrically powered vehicle (EV) includes a plurality of monitor modules each coupled to at least one of the plurality of batteries and configured to monitor the vo
6112575 Method and apparatus for vehicle exhaust gas pollutant mass flow measurement September 5, 2000
A method and apparatus to provide a very compact and low power measurement of vehicular (automobile) exhaust emissions with results similar to those obtained with traditional CVS dynamometer lab emissions equipment. The sample dilution necessary for the analysis is performed by a compute
6018224 Anti-clipping circuit for induction motor drive system January 25, 2000
A feedback circuit prevents clipping of the inverter drive signals for a polyphase induction motor. The circuit senses the electromotive force (e.m.f.) of the motor and regulates the slip frequency as a function of the difference between the sensed motor e.m.f. and the DC power supply
5642010 Rotor construction for alternating current induction motor June 24, 1997
The present invention pertains to an improved rotor bar design and method of fabrication of asynchronous motors using such rotor bars. The rotor bar design employs "T"-shaped rotor bars that are interleaved around a magnetic core forming a rotor having a minimum amount of bonding int
5355070 Induction motor drive stability control circuit October 11, 1994
A circuit generates phase pole command signals for controlling operation of an induction motor. To minimize instabilities occurring within the motor, a stability control circuit generates a phase shift signal, which is input to reference signal generators to adjust phase reference signal
5341075 Combined motor drive and battery recharge system August 23, 1994
A combined battery recharge and motor drive system employs an essentially conventional polyphase pulse width modulated (PWM) inverter and a polyphase motor which may be reconnected to operate in a battery recharge mode. Single phase or three-phase AC power from an external source is
