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.

A connector includes: a terminal fitting having a body portion; and a housing having a cavity that receives the terminal fitting, wherein the body portion has a first protrusion that protrudes from an outer surface of the body portion and an interference avoiding portion, wherein the first protrusion and the interference avoiding portion are disposed to be opposed to each other substantially in a diagonal line on a virtual projection plane, and wherein the cavity is formed with, in an inner surface thereof, a first groove into which the first protrusion is allowed to enter only when the terminal fitting has a proper insertion posture relative to the cavity and an interference portion that is formed to swell from the inner surface of the cavity to narrow a gap with the interference avoiding portion.

Electrical connector with terminal orientation features

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.

Cell voltage detecting system and drive voltage maintaining method

An apparatus measures a voltage of a cell while scanning a group of cells in a cell stack, in which a plurality of cells is electrically connected in series. The apparatus has a first switching device and a voltage detecting device. The first switching device is connected in series with a signal line carrying a voltage of a cell. The voltage detecting device detects the voltage of the cell, which is electrically connected with signal lines carrying voltages of cells belonging to a group. When the first switching device is electrically connected with a connecting point between two successive groups of cells, the first switching device is shared by the two groups.
