Abstract: In an electric charging system, an electric charger and an electric vehicle is connected via a charging cable, and charging power is provided to a battery of the electric vehicle via the charging cable. The electric charger calculates a voltage drop based on a supply current Is of the electric charger and an electric resistance of the charging cable. The electric charger compares a supply voltage of the electric charger with a determination value, and, if the supply voltage reaches the determination value, determines that the battery is charged to a fully-charged state. The determination value is updated by adding the voltage drop to a preset determination base value so as to take the voltage drop of the charging cable into account.

Abstract: A vehicle speed acquisition unit acquires speed information indicating a vehicle speed. An output acquisition unit acquires output information indicating an output of a drive unit that drives the vehicle. An output rate derivation unit derives an output rate indicating a ratio of the output to a rated output of the vehicle at the current vehicle speed. A waste derivation unit derives waste information indicating a degree of waste of energy consumed by the vehicle. A display unit displays a waste status of the energy. When the speed is within a predetermined speed range and the output rate is within a preset first output range, the waste derivation unit derives the waste information indicating that the waste of energy when the speed is high is less than when the speed is low, even when the output rate is the same.

Abstract: There are provided a power supply system, an electric vehicle and a charging adapter. Electric power from a commercial power supply is distributed to electric lines by way of a distribution board and provided to electric apparatuses and an electric vehicle from the electric lines. When power consumption of electric apparatuses exceeds a predetermined value upon charging the electric vehicle, charging power to be supplied to the electric vehicle is decreased. Decreasing the charging power to the electric vehicle can avoid the restriction of the use of the electric apparatuses, thereby improving user's satisfaction.

Abstract: 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.

Abstract: In an electric charging system (and electric vehicle), Electric-charger-side data Ds are calculated by subjecting an electric-charger-side supplied voltage Vs to filter processing, and electric-vehicle-side data Dr are calculated by subjecting an electric-vehicle-side received voltage Vr to filter processing. A reference point ?1 is set for the electric-charger-side data Ds on the basis of the variation in the rise rate of the electric-charger-side data Ds. Likewise, a reference point ?2 is set for the electric-vehicle-side data Dr based on variation in the rise rate of the electric-vehicle-side data Dr. When an insulation failure between the electric charger and the electric vehicle is determined, a time lag T between the electric-charger-side data Ds and the electric-vehicle-side data Dr is calculated based on the reference points ?1 and ?2, and the electric-charger-side data Ds and the electric-vehicle-side data Dr that are synchronized based on the time lag T are compared.

Abstract: In an electric charging system, a charging cable of an electric charger is connected to an electric vehicle, and a supply voltage at the electric charger is temporarily raised and dropped. A receiving voltage at the electric vehicle rises and falls in conjunction with to the supply voltage. Accordingly, a feature point is assigned to each of electric charger data obtained by applying a filtering process to the supply voltage and vehicle data obtained by applying a filtering process to the receiving voltage. Then a time lag between the electric charger data and the vehicle data due to filtering processing is calculated based on the feature points. Upon determining an insulation failure and the like between the electric charger and the electric vehicle, the electric charger data and the vehicle data are synchronized based on the time lag and then compared.

Abstract: There is provided an electric charging system in which an electric charger and an electric vehicle are connected by a charging cable. The electric charger calculates a voltage drop amount in the charging cable on the basis of a supplied current at the electric charger side and an electric resistance of the charging cable. The electric charger also compares a determination voltage with a supplied voltage at the electric charger side and determines that a battery has been charged to a fully charged state when the supplied voltage reaches the determination voltage. The determination voltage used for such full charge determination is updated by adding the voltage drop amount to a basic determination voltage that is set in advance.

Abstract: 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.
