摘要:
A battery charging control device for controlling a power generation device installed in an electric vehicle sets a battery energy management area using a current position of a host vehicle as a reference, detects at least one travelable route within the battery energy management area, calculates a battery energy management upper limit value and a battery energy management lower limit value on the basis of a maximum value and a minimum value of energy values required to travel to respective points on the travelable route from the current position, and calculates a battery energy management width by subtracting the management lower limit value from the management upper limit value. When the battery energy management width is not within a predetermined range, the battery energy management area is modified so as to enter the predetermined range. As a result, battery charging is controlled such that a magnitude relationship between the battery energy management upper limit value and the battery energy management lower limit value does not reverse.

An object of the present invention is to provide a battery state estimation device and a battery state estimation method which identify parameter of a secondary battery with high accuracy. A current and a terminal voltage of secondary battery are detected, then by using the current measured value and terminal voltage measured value thus detected, the terminal voltage of secondary battery based on predetermined battery model is estimated, and the parameter of the secondary battery is identified such that a difference between terminal voltage measured value and voltage estimated value is converged to zero. In the identifying of parameter of secondary battery, the terminal voltage measured value and terminal voltage estimated value are subjected to filter treatment by low pass filter having a common high frequency breaking characteristic and the terminal voltage measured value and terminal voltage estimated value subjected to the filter treatment are used.

Disclosed is a technique for quickly detecting a defect of a portion welded by laser beam welding. Specifically disclosed is a welding step in which a welding device is used, the welding device welding an object to be welded with a pulsed laser. In the welding step, a first photodetector receives only infrared rays having a wavelength allowing detection of a keyhole formed in a molten pool from among infrared rays radiating from a welded portion during the welding of the object, and an analyzer determines quality of the welded portion on the basis of intensity of the infrared rays received by the first photodetector.

There is provided a plasma processing apparatus capable of stably generating plasma by suppressing oscillation of a plasma potential, and capable of preventing contamination caused by sputtering a facing electrode made of metal. A high frequency bias power is applied to an electrode within a mounting table for mounting a target object thereon. An extended protrusion 60 is formed at an inner peripheral surface of a cover member 27. The extended protrusion 60 is formed toward a plasma generation space S and serves as a facing electrode facing an electrode 7 within a mounting table 5 with the plasma generation space S therebetween. A ratio of a surface area of the facing electrode with respect to that of an electrode for bias (facing electrode surface area/bias electrode area) is in a range of from about 1 to about 5.

Provided is a method of manufacturing a battery having an electrode module including: a positive plate having a cathode collector portion formed by attaching a lead member to a cathode substrate made of a foamed metal plate; and a cathode collector plate welded to the cathode collector portion. The method includes: a pre-welding positive plate forming process of forming a pre-welding positive plate, which is the positive plate before welding, such that the pre-welding positive plate has a projection projecting from a pre-welding cathode collector portion, which is the cathode collector portion before welding; and a welding process of melting a pre-welding cathode collector plate to weld it to the projection. In the pre-welding positive plate forming process, the projection is formed into such a shape that the condition that S≦1.3W is satisfied, where W and S represent the width and the circumferential length of the projection, respectively.

A network system enables controlling an image input device without requiring a driver that depends on the computer environment. A client terminal has a component that acquires a web page having an embedded scanner control script that controls image input from a scanner; a component that sends an image acquisition request through an interface board to the scanner as controlled by the scanner control script; and a component that gets an image from the scanner as a response to the image acquisition request as controlled by the scanner control script. The interface board receives the image acquisition request, and sends the image scanned by the scanner based on the received image acquisition request to the client terminal.
