    Abstract: A lithium ion battery has a flat wound electrode assembly, a nonaqueous electrolyte, and a battery case. The nonaqueous electrolyte contains an electrically insulating inorganic aggregate and is formed of an impregnating electrolyte impregnated into the flat wound electrode assembly and a surplus electrolyte not impregnated into the flat wound electrode assembly. Letting the flat wound electrode assembly be divided into a planar region where the electrode surfaces are planar surfaces and a lower wound curved region which is positioned vertically downward from the planar region and where the electrode surfaces are curved, a boundary plane that includes the boundary between the planar region and the lower wound curved region, the inorganic aggregate amount MO included in a space which is below the boundary plane and the inorganic aggregate amount MI included in the impregnating electrolyte within the flat wound electrode assembly satisfy the relationship MO>MI.

  • Publication number: 20180264703
    Abstract: Provided is a method for forming resin film capable maximizing the effective width of the resin film while suppressing neck-in and so increasing the material utilization. The method includes: drawing molten resin extruded downward from a die exit by a cooling roll; blowing air to both ends of the molten resin from an air-blowing nozzle to cure the both ends of the molten resin while cooling the molten resin on a surface of the cooling roll for solidification. For an effective width of the resin film to be formed having a thickness in a predetermined thickness range, a target effective width is set. An amount of air to be blown and a distance from the air-blowing nozzle to the molten resin are set to form the resin film having an effective width of the target effective width or more. The resin film is formed while blowing air under the conditions.

  • Publication number: 20180269521
    Abstract: A method of producing a sulfide solid electrolyte material includes: forming an intermediate having crosslinking sulfur but no Li2S, by vitrifying, in a first vitrification process, a starting material composition obtained by mixing Li2S and a sulfide of a group 14 or group 15 element such that a proportion of Li2S with respect to the sum total of the Li2S and the sulfide of a group 14 or group 15 element is smaller than a proportion of Li2S required for the sulfide solid electrolyte material to obtain an ortho composition; and eliminating the crosslinking sulfur by vitrifying, in a second vitrification process, an intermediate-containing composition resulting from mixing a bond cleaving compound, which cleaves a bond of the crosslinking sulfur, with the intermediate.

  • Publication number: 20180265077
    Abstract: The control device of a four-wheel drive vehicle is applied to a four-wheel drive vehicle having a differential restriction device which can change a differential restriction degree between a front wheel rotary shaft and a rear wheel rotary shaft, a braking device can separately change a braking force of the front wheels and a braking force of the rear wheels. The control device determines whether a specific state which has a high possibility that a state where a rear wheel slip ratio becomes larger than a front wheel slip ratio is generated occurs assuming that the differential restriction degree is set to a first degree when the differential restriction degree is set to a second degree so as not to allow the differential operation and change the differential restriction degree from the second degree to the first degree when it is determined that the specific state has occurred.

    Abstract: A battery control device includes a positional information acquiring unit, a deposition-risk-geographic-point storing unit, a determination unit, and a deposition-deterring-mode executing unit. The positional information acquiring unit is a processing unit that acquires positional information of a vehicle. The deposition-risk-geographic-point storing unit stores deposition risk geographic points. The determination unit determines whether or not the vehicle passes at least one of the deposition risk geographic points stored in the deposition-risk-geographic-point storing unit based on the positional information of the vehicle that is acquired by the positional information acquiring unit. The deposition-deterring-mode executing unit controls a battery based on a predetermined deposition-deterring mode, if the determination unit determines that the vehicle passes the at least one of the deposition risk geographic points.

  • Publication number: 20180269504
    Abstract: A fuel cell system includes: a pressure regulating valve that reduces a pressure of a fuel gas; a fuel gas supply passage having a first passage extending between a fuel cell and the pressure regulating valve and a second passage extending from the pressure regulating valve via a cutoff valve to a fuel gas supply source; a pressure sensor that detects a pressure of the fuel gas inside the first passage; and a controller to which the cutoff valve and the pressure sensor are connected. When a pressure value detected by the pressure sensor is an abnormal value, the controller closes the cutoff valve and performs pressure reduction processing for the first passage. Thereafter, the controller judges that the pressure regulating valve has failed when the pressure value detected by the pressure sensor has lowered, whereas the controller judges that the pressure sensor has failed when the pressure value detected by the pressure sensor has not lowered.

  • Publication number: 20180265073
    Abstract: A hybrid vehicle comprises an engine configured to be driven with a fuel supplied from a fuel tank; a motor configured to input and output a power for driving; and a control device configured to drive the engine and the motor. When a remaining amount of fuel in the fuel tank is lower than a predetermined level, the control device provides a smaller absolute value of a torque lower limit value of the motor during deceleration at a vehicle speed of lower than a predetermined vehicle speed, compared with an absolute value during deceleration at the vehicle speed of not lower than the predetermined vehicle speed. This configuration suppresses a deceleration torque of a large absolute value from being output from the motor during deceleration at the low vehicle speed and accordingly suppresses a loss of the motor or the like from becoming greater than the regenerative energy.
