  • Patent number: 11984833
    Abstract: An electric vehicle control device includes a first inverter controlling a first group defined by induction motors, and a second inverter controlling a second group defined by induction motors. The first inverter and the induction motors of the first group are connected to each other by a first conductor. The second inverter and the induction motors of the second group are connected by a second conductor. A first length is equal to or less than three times the average value of a second length and a third length. The first length is an inter-center distance between the first conductor and the second conductor, the second length is the maximum length of a conductor portion of the first conductor in the cross section of the first conductor, and the third length is the maximum length of a conductor portion of the second conductor in the cross section of the second conductor.

  • Publication number: 20180013289
    Abstract: An electric power control system for controlling supply and consumption of electric power in a system power supply, a storage battery and an electric power load, said electric power control system including: an estimated value correction unit configured to obtain a difference between a past power control estimated value and a past actual performance value, and to shift a power control estimated value obtained as a result of estimation in a predetermined period to an extent corresponding to said difference, thereby correcting the power control estimated value, wherein said past power control estimated value is a value obtained as a result of estimation performed in a past time relative to said predetermined period, and said past actual performance value is a value obtained as an actual result in the past time; and a power control unit configured to control supply and consumption of electric power in the system power supply, the storage battery, and the electric power load, based on the power control estimated

  • Publication number: 20170324244
    Abstract: A power demand estimation apparatus, comprising: an error measuring unit configured to measure an error of estimated power demand estimated with respect to one or more customer facilities; an error addition unit configured to obtain an added error obtained by adding errors measured with respect to segment periods in a unit term for correction, the unit term for correction including a predetermined number of consecutive series of segment periods; and a power demand estimation unit configured to estimate power demand values with respect to the respective segment periods, and correct the estimated power demand value estimated with respect to last predetermined number of segment period in the unit term for correction, based on an added error obtained with respect to the segment periods preceding the last predetermined number of segment period in the unit term for correction.

  • Patent number: 9781979
    Abstract: A surface fastener member includes left and right longitudinal protective wall sections and front and rear lateral protective wall sections. Each of the lateral protective wall sections includes an outer first lateral wall section and an inner second lateral wall section. The first lateral wall section is continuously placed between the left and right longitudinal protective wall sections at a predetermined height. The second lateral wall section includes a plurality of divided lateral wall bodies which are intermittently placed along a width direction, and a plurality of second engagement elements. The distance is set smaller than a mounting pitch of the first engagement elements in the longitudinal direction of the surface fastener member. According to this, when the molded surface fastener is integrally molded on a cushion body, it is possible to prevent resin material from entering an engagement element region of the surface fastener member.

  • Publication number: 20170256952
    Abstract: A power management system includes: a power consumption estimation unit which, based on a first filter estimation function to make estimation by measured value of power consumption in a limited period of past measurement, estimates power consumption of next period of measurement in a first customer facility as an estimated power consumption; a power generation estimation unit which, based on a second filter estimation function to make estimation by measured value of power generation in a limited period of past measurement, estimates power generation by a power generator of next period of measurement in the first customer facility as an estimated power generation; an surplus power estimation unit which obtains an estimated surplus power which is a difference between the estimated power generation and the estimated power consumption; and a power management unit for controlling each of the charge and discharge of the storage battery.
