Patent number: 8994317Abstract: An output control apparatus for an electric motor includes a phase-current instruction-value setting device, a draw-current allowable-value storage device, a phase-current allowable-value setting device, and a phase-current instruction-value limiting device. The draw-current allowable-value storage device is configured to store a draw current allowable value of an electric storage device corresponding to an allowable current value of a system disconnecting-connecting device provided in a power system from the electric storage device to the electric motor. The phase-current allowable-value setting device is configured to set a phase current allowable value based on the draw current allowable value and an ON time of a switching element in a power converter. The phase-current instruction-value limiting device is configured to compare the phase current instruction value with the phase current allowable value to limit the phase current instruction value so as not to exceed the phase current allowable value.Type: GrantFiled: February 4, 2013Date of Patent: March 31, 2015Assignee: Honda Motor Co., Ltd.Inventors: Masahiko Akiyama, Yuji Minoda

Patent number: 8274292Abstract: In a cell voltage detecting system detecting cell voltages of a fuel cell connected in series, a voltage detector detects cell voltages. An auxiliary power supply generates a voltage equal to or greater than a minimum voltage for driving the voltage detector at positive and negative terminals thereof. First and second diodes are connected to a positive drive terminal of the voltage detector to supply the power to the drive terminal of the voltage detector from a high voltage side between the fuel cell or the auxiliary power supply. A negative terminal of the fuel cell, the negative drive terminal, and the negative terminal of the auxiliary power supply are connected to have a same potential. A method of maintaining a drive voltage for the voltage detector is also disclosed in which the drive voltage for the voltage detector is supplied from the high voltage side.Type: GrantFiled: January 22, 2010Date of Patent: September 25, 2012Assignee: Honda Motor Co., Ltd.Inventors: Yuji Minoda, Toshiaki Ariyoshi
