  • Publication number: 20200233037
    Abstract: According to one embodiment, an evaluation device for an energy storage device includes first processing circuitry and second processing circuitry. The first processing circuitry acquires data items including an amount of charge and a voltage value measured in a measurement period from the energy storage device, the energy storage device being charge-discharge-controlled according to charge-discharge command values. The second processing circuitry generates a representative data item of voltage values for amounts of charge, based on the data items acquired for the measurement period; and evaluates a degradation state of the energy storage device, based on a relative change between a plurality of the representative data items corresponding to a plurality of the measurement periods.

  • Publication number: 20200217896
    Abstract: According to one embodiment, a device for evaluating an energy storage device includes first processing circuitry and second processing circuitry. The first processing circuitry detects a plurality of times at which an amount of charge of the energy storage device satisfies a threshold condition, based on measurement data on the energy storage device in operation, selects a plurality of time intervals, calculates a charge-discharge efficiency in each of the time intervals based on charge-discharge command values belonging to the time interval, and divides a set of the charge-discharge efficiencies into a plurality of clusters and generates characteristic information on the clusters based on at least one of the measurement data and the charge-discharge command values. The second processing circuitry generates output data for displaying: transition data indicating transition of the charge-discharge efficiency belonging to the cluster; and characteristic information on the cluster.

  • Publication number: 20200003839
    Abstract: According to one embodiment, an evaluation device includes first processing circuitry and second processing circuitry. The first processing circuitry calculates a feature value of an energy storage device based on voltage values measured from the energy storage device being subjected to charge-discharge-control according to charge-discharge command values. The second processing circuitry derives an evaluation function of a degradation state of the energy storage device according to a difference between a distribution of the charge-discharge command values and a reference distribution. The second processing circuitry evaluates the degradation state of the energy storage device, based on the evaluation function and the calculated feature value.

  • Patent number: 10505406
    Abstract: According to one embodiment, an electrical machine includes a rotor and an armature. The armature includes first to third stator cores, and an armature coil. The first and second stator cores are arranged along a direction of a rotation axis of the rotor. The third stator core is arranged opposite to the first and second stator cores. The armature coil is provided between the first and second stator cores. The first and second stator cores have a same shape and each include magnetic poles and a first positioning part. The third stator core includes a second positioning part. A relative phase angle of the first stator core and a relative phase angle of the second stator core in the rotation direction are set by using the first positioning part and the second positioning part.
