摘要:
In a multiple power supply apparatus installed in a vehicle, a first power supply system includes a generator and a first battery. The generator is driven by an operation of the engine. The first battery is chargeable by an electrical output of the generator. A second power supply system includes a second battery. The second battery works to supply electrical power to an electrical load installed in the vehicle. A power transfer module is operative to transfer electrical power supplied from the first power supply system based on at least one of the electrical output of the generator and a charged level of the first battery to the second power supply system. The power transfer module is integrally joined to the first battery to constitute a battery module.

According to the present invention, a control apparatus for an electric generator includes a power generation cost determiner determining a power generation cost of the generator, a threshold determiner determining a threshold of power generation cost as a function of a state of charge of an electric energy storage device, a comparator comparing the power generation cost of the generator with the threshold, and a controller. When the power generation cost of the generator is lower than the threshold, the controller controls the generator to generate an increased amount of electric power, so as to both charge the electric energy storage device and feed an electrical load. Otherwise, when the power generation cost of the generator is higher than the threshold, the controller controls the generator to generate a decreased amount of electric power, so as to allow the electric energy storage device to discharge to feed the electrical load.

An apparatus is provided to control a power voltage on a power-supplying line extending from a generator and connecting to a battery and eclectic loads. The apparatus is mounted on a vehicle and comprises a detecting device, a calculator, and a controller. The detecting device detects pairs of voltage and current of the battery. The calculator calculating a control current on the basis of the detected pairs of voltage and current and a target voltage for the power voltage. The pairs of voltage and current are used to calculate an internal resistance and/or a regression line of the battery. The controller controlling a charge and discharge current of the battery on the basis of the control current so that the power voltage is controlled to the target voltage.

Provided is an Mg alloy and a method for producing same able to demonstrate high strength without requiring an expensive rare earth element (RE). The high-strength Mg alloy containing Ca and Zn within a solid solubility limit and the remainder having a chemical composition comprising Mg and unavoidable impurities is characterized in comprising equiaxial crystal particles, there being a segregated area of Ca and Zn along the (c) axis of a Mg hexagonal lattice within the crystal particle, and having a structure in which the segregated area is lined up by Mg3 atomic spacing in the (a) axis of the Mg hexagonal lattice. The method for producing the high-strength Mg alloy is characterized in that Ca and Zn are added to Mg in a compounding amount corresponding to the above composition and, after homogenization heat treating an ingot formed by dissolution and casting, the above structure is formed by subjecting the ingot to hot processing.

A radio-controlled wristwatch that determines whether or not illuminance of light irradiating a solar cell is high, using plural criteria but without directly measuring voltage or current. The wristwatch includes: a solar cell; a control circuit which stops operation under a predetermined condition; and an illuminance detection circuit which indicates illuminance of light irradiating the solar cell being higher than a given threshold value. The wristwatch switches the given threshold value between a first and a second value, larger than the first value, starts the control circuit in a stop state when a signal indicating that the illuminance is higher than the first value is output, receives a satellite signal containing time information from a satellite when a signal indicating that the illuminance is higher than the second value is output, and displays time corresponding to the time information contained in the received satellite signal.
