摘要： A vehicle speed determining device determines a running speed of a vehicle, on the basis of pulses received from a vehicle speed sensor. A first determination that the running speed of the vehicle has been zeroed is made, if a next pulse has not been received from the sensor, within a predetermined first length of time after the reception of a last pulse from the sensor. A second determination that a period of the next pulse to be received next is abnormally long is made, if said next pulse has not been received within a predetermined second length of time after the reception of the last pulse. If the second determination is made, the first determination is inhibited until the next pulse has been received.

摘要： A control device has a coupling determination sensor for detecting external connection of a charge table. When the connection of the charge cable is detected according to a signal from the sensor, the control device activates an electric device connected to a communication line of a charge-time-dedicated power supply system. Since the control device of the invention can activate only the electric device related to the charging while keeping electric devices not related to the charging at rest, and therefore prevents wasteful electric power consumption.

摘要： A device and method is provided that can detect overcharge reliably by separating heat generated by internal resistance and heat chemically generated upon overcharging in a secondary battery. Based on the temperature of the secondary battery detected every first predetermined time by a battery temperature detection section, a temperature gradient operation section calculates a temperature gradient indicating a temperature increase per unit time for every second predetermined time that is longer than the first predetermined time. When a temperature gradient determination section determines that the temperature gradient is larger than a predetermined temperature gradient threshold, which is preset according to the charged state of the secondary battery, N times in a row (where N is a natural number), a fully charged state of the secondary battery is detected.

A connector housing with a terminal fitting-accommodating hole formed therein is provided with a shielding metal shell, into which accommodating hole is fitted a terminal fitting attached to a shielded cable such that the shield of the shielded cable is connected with the metal shell via a connecting member fitted on the shield. The connector housing is further provided on its outer periphery with a flange for fixing the connector housing in a connector-mounting hole formed in the casing of the instrument and with a seal ring for sealing the mounting hole. The metal shell is extended to have a portion thereof exposed on the surface of the flange facing toward the casing.

摘要： When such a failure as the output from a voltage sensor becomes unavailable is detected, a controller controls a connecting section to disconnected state and controls a voltage converter to voltage unconverted state so that the voltage of a positive pole bus is outputted to the terminal of the voltage converter on the connecting section side, and performs voltage control of the positive pole bus based on the output from a voltage sensor in place of the output from the voltage sensor. Consequently, a power supply unit for a vehicle which can perform escape running while maintaining the traveling performance as much as possible even upon occurrence of failure in the sensor is provided.

摘要： In regenerative braking mode, an inverter converts, according to PWMC signal from a control unit, an AC voltage generated by a motor into a DC voltage to supply the converted DC voltage to an up-converter which down-converts the DC voltage to charge a DC power supply. The control unit receives voltage V2 from a voltage sensor to stop the up-converter if voltage V2 is higher than a predetermined value. The control unit further receives voltage Vf from a voltage sensor that is applied to a DC/DC converter and stops the up-converter if voltage Vf is higher than a predetermined value. Moreover, the control unit receives voltage V1 of the DC power supply from a voltage sensor to stop the up-converter if voltage V1 does not match voltage V2.

摘要： Frequency of judgment of welding of relays is increased to increase likelihood of early detection of welding. It is determined that a battery 22 is not being recharged or discharged when a vehicle speed V of an electric vehicle is approximately 0 and a brake pedal 54 is pressed, and a switching element of an inverter 24 is controlled to be switched to discharge electric charges which are stored in a capacitor 44. After discharging, relays 30, 32 are turned off, and voltages RV1, RV2 between the terminals of the relays 30, 32 are detected by voltmeters 40, 42 to judge whether either of the voltages RV1, RV2 has a threshold value RVref (approximate value 0) or less. When it is so determined, it is judged that the relays 30, 32 are welded, and an LED 70 is illuminated.
