摘要： A creep travel capability of an electric vehicle is secured when an abnormality occurs in a brake sensor. When an accelerator operation amount reaches 0% in a low vehicle speed region, a target creep torque is set, whereupon a motor-generator is controlled toward the target creep torque. The target creep torque is reduced as a brake pedal is depressed in order to suppress heat generation and the like in the motor-generator during vehicle braking. Hence, in an electric vehicle in which the target creep torque is varied in accordance with the brake operation amount, when an abnormality occurs (step S11) in a brake sensor for detecting a brake operation amount, a preset prescribed creep torque is employed as the target creep torque regardless of the brake operation amount (step S15). The prescribed creep torque is set at a required magnitude for securing the creep travel capability.

摘要： The present invention provides a control apparatus for an electric vehicle which improves safety in an electric vehicle capable of traveling using creep torque. The electric vehicle includes a motor/generator for driving vehicle wheels. In a low vehicle speed region during startup or the like, creep torque is output from the motor/generator even when an accelerator pedal has not been operated, and therefore the electric vehicle can be started gently. The electric vehicle is also provided with a friction brake system for applying vehicle braking through frictional force. When an EV control unit for setting a target creep torque of the motor/generator determines that an abnormality has occurred in the friction brake system (step S20), the target creep torque is set lower than normal (step S30). Therefore, when an abnormality that may cause a reduction in a braking force occurs in the friction brake system, a propulsive force of the electric vehicle can be reduced, and as a result, the safety of the electric vehicle can be improved.

摘要： When a battery of an electric vehicle charged with an external power source (AC 100 V), the electric vehicle and the external power source are connected with each other by the intermediary of a charging cable. Upon this charging, it is determined whether or not an input voltage from the external power source is 95 V or more. When the input voltage is less than 95 V, that is, a decline of the voltage in the charging cable is large, since a wiring resistance in the charging cable possibly increases, an upper limit of an output power to the battery is reduced. Consequently, the electric power delivered from the external power source can be limited, and thereby excessive heat generation is inhibited and safety is ensured. Furthermore, since the output power is caused to be limited when the wiring resistance possibly increases, the battery can be charged continuously.

摘要： An electric vehicle includes a power receiving connector that is connected to a battery via a relay, and an electric charger includes a power supply connector that is connected to the power receiving connector. When a high voltage is applied to the power receiving connector due to a weld failure of the relay, a warning lamp flashes to notify an operator of the risk. Then the connection state is detected between the connectors. When the connectors are not connected to each other, a warning buzzer issues a warning sound. When the connectors are connected to each other, the warning buzzer is turned off. The power receiving connector is covered by the power supply connector in this manner, the operator is unlikely come in contact with the power receiving connector, and thus the output of a warning sound from the warning buzzer is stopped.

摘要： There are provided an electric charging system, an electric vehicle and an electric charger. Upon charging a battery, power supply lines of an electric charger are connected to the power receiving lines of an electric vehicle 12. The power receiving lines have a relay. The electric charger has a voltage sensor that measures a voltage between the power supply lines. The electric charger has a voltage processing portion that applies filtering to the voltage. Upon charging when charging power is supplied from the electric controller, a filtering process with a stability-oriented first filter is applied to the voltage.

摘要： To secure safety in an electric vehicle during charging, the electric vehicle is provided with a high voltage battery and a charging port portion for charging the high voltage battery. A power reception connector and a connector locking mechanism are provided in the charging port portion, and a fitting hole is formed in a power supply connector disposed on an external power supply side. The connector locking mechanism is switched between a restrained condition, in which a locking pin is inserted into the fitting hole, and a released condition, in which the locking pin is retracted from the fitting hole. A vehicle control unit for controlling the connector locking mechanism switches the connector locking mechanism to the restrained condition when a door is locked, and switches the connector locking mechanism to the released condition when the door is unlocked. Thus, the connection condition between the power reception connector and the power supply connector can be maintained even when a passenger locks the door and moves away from the electric vehicle, and as a result, safety can be secured during charging.
