  • Publication number: 20180100897
    Abstract: A semiconductor integrated circuit is capable of being supplied with battery current information and battery voltage information. The semiconductor integrated circuit includes a memory function, a current integrating function, a voltage-based state of charge operating function, a current-based state of charge operating function, a comparison determination function, a correcting function, and a resistance deterioration coefficient output function. The memory function stores the relation between a state of charge of a battery and an internal resistance deterioration coefficient thereof. The full charge capacity outputted from the correcting function and the internal resistance deterioration coefficient outputted from the resistance deterioration coefficient output function are stored in the memory function when a voltage-based state of charge and a current-based state of charge compared by the comparison determination function are determined to substantially coincide with each other.

    Abstract: A battery control IC includes a remaining amount estimation computing unit. The remaining amount estimation computing unit switches, during discharging of a battery pack, a first estimating method, in which a direct current resistance is obtained from a change in a voltage value of a battery voltage and a change in a current value of a current flowing through the battery pack at a start of discharging of the battery pack and a full charge capacity of the battery pack is obtained based on information set in advance indicating a relation between the direct current resistance and the full charge capacity, and a second estimating method, in which the full charge capacity of the battery pack is estimated from a relation between an open-circuit voltage predicted from the battery voltage and a used charge amount obtained from information of the current flowing through the battery pack.

  • Patent number: 7464491
    Abstract: A pair of casual shoes such as flip-flops are packaged for sale so as to have the general appearance of an essentially spherical ball. Each shoe has a flexible sole portion and an upper portion connected to at least part of the periphery of the sole portion by stitching, which extends around the entire sole portion periphery. The sole portion of each shoe is flexed generally into a U-shape and also is flexed transversely to the length thereof, and then the two U-shapes are interfitted with the toe and heel regions of one shoe fitting against the instep region of the other shoe. An elongate cord is laced between the stitching around the peripheries of the two sole portions so as to hold the two shoes together in the ball shape but removal of the cord release the two shoes for separation and opening out into a pair of flip-flops.

  • Patent number: 7165526
    Abstract: A direct injection engine and a controller for the engine, which can realize super-retard combustion under high backpressure and can minimize an emission amount of HC at the startup. A cavity is formed in a piston such that fuel spray injected from a fuel injection valve is blown into the cavity. An obstacle member, such as a step, is provided in the cavity to decelerate or stop the fuel spray blown into the cavity. A mount position, mount posture, nozzle structure, injection port shape, etc. of the fuel injection valve are set such that the fuel spray injected from the fuel injection valve is made up of a lead fuel spray component directed toward the ignition plug and having a penetration to extend long beyond the ignition plug, and a main fuel spray component directed toward the piston, thereby enabling the super-retard combustion to be performed under high backpressure.

    Abstract: The amount of air to be introduced is controlled for each cylinder, whereby it is intended to make it possible to control the torque generated in each cylinder, perform an ultra-lean burn operation, purify the exhaust gas, and increase the output of an engine. An air flow control valve adapted to be on-off controlled in accordance with an operated quantity of an accelerator pedal is disposed in each branch pipe or intake port. The air flow control valve may be a throttle valve disposed in each branch pipe or it may be a variable intake valve for opening and closing the intake port.
