    摘要： A battery discharge gas control system, which releases a hydrogen gas generated from the battery assembly when the battery assembly is charged and discharged, is capable of keeping the battery structure highly resistant to water or humidity. The battery discharge gas control system has a battery having a gas release port, a passage connected to the gas release port, a control valve connected to the passage, a pressure sensor for detecting a pressure in the passage, and a control circuit for opening the control valve to release a gas generated by the battery from the passage, depending on the pressure in the passage as detected by the pressure sensor. During a period of time in which no hydrogen gas is generated or a generated hydrogen gas is not plenty enough to be released while the battery is being charged or discharged, the passage is closed for thereby keeping the battery structure highly resistant to water or humidity. The control valve has a solenoid-operated valve openable in response to a control signal outputted by the control circuit, and a relief valve mechanically openable depending on the pressure in the passage. Even in the event of a failure of the solenoid-operated valve, the relief valve is mechanically opened depending on the pressure in the passage, thereby protecting the passage from damage.

    摘要： An initial output of a secondary battery on an electrically propelled vehicle is set to a value which is at least the sum of an established power output of a motor, an output reduction due to the memory effect of the secondary battery, and an allowable output reduction due to aging of the secondary battery. Since the established power output of the motor is determined taking into account the output reduction due to the memory effect and the output deterioration due to the aging, a minimum power output which the battery has as its capability is prevented from dropping below the established power output within the prescribed number t=n of times that the battery is charged and discharged, even when the output reduction and deterioration take place. Therefore, the driver, which is the user of the electrically propelled vehicle, does not feel a reduction in the power performance of the electrically propelled vehicle, i.e., a reduction in the established power output of the motor, caused by the output reductions of the battery.

    摘要： A method and apparatus for charging a battery which is operable to normally charge the battery at a first state of charge setting, to determine when the battery has been undercharged a predetermined number of times, and to charge the battery at a second state of charge setting after the battery is undercharged the predetermined number of times. The second state of charge setting is greater than the first state of charge setting. The method includes determining when the state of charge of the battery is below a predetermined level, charging the battery at the first state of charge setting, calculating a number of charging times when the battery was charged below the predetermined level after the last time the battery was charged at the predetermined level, and charging the battery with a second state of second charge setting when the calculated number of charging times equals a predetermined number. The apparatus includes a sensor for sensing the state of charge of the battery, a counter for counting the number of charging times that the battery was charged below a predetermined level after the last time the battery was charged to the predetermined level, and a charger for applying the second state of charge setting when the number of charging times counted by the counter equals the predetermined number.

    摘要： For measuring a temperature with a thermistor, an electrical circuit including the thermistor and resistors for voltage division has to be maintained in the normally energized state and a variation in the voltage caused by resistance variation is detected. This requires a considerable amount of power consumption. On the other hand, thermal reed switches SW1 to SWn are mounted on the surfaces of the unit cells 1-1 to 1-n included in the battery pack 10. Each of the thermal reed switches is connected at one end to a common power source VDD and at the other end to a corresponding input terminal of a selector switch 20. The selector switch 20 is responsive to a switch signal from a determining unit 30a for passing selectively and periodically input signals of the input terminals to the determining unit 30a which in turn detects the temperature of a corresponding unit cell on the basis of the input signal selected by the switch signal.

    摘要： A supercharging pressure control system for supercharged internal combustion engines includes a supercharging pressure control valve for controlling supercharging pressure of intake air, supplied by a supercharger. A desired value of the opening of the supercharging pressure control valve is determined depending on operating conditions of the engine. When the supercharging pressure detected has reached the desired value of the supercharing pressure, a feedback control mode is selected, in which the opening of the supercharging pressure control valve is controlled so as to make the supercharging pressure detected equal to the desired value of the supercharging pressure. On the other hand, when an actual value of the opening of the supercharging pressure control valve determined during the feedback control becomes smaller than the desired value of the opening of the supercharging pressure control valve, an open-loop control mode is selected, in which the opening of the supercharging pressure control valve is controlled to the desired value of the opening of the supercharging pressure control valve.
