STORAGE BATTERY, BATTERY UNIT, AND BATTERY MONITORING DEVICE
A storage battery 10 comprises: a positive electrode layer; a negative electrode layer; and a separator that is disposed between the positive electrode layer and the negative electrode layer. The separator is provided in a form containing a substance that has a dielectric constant which changes according to the temperature. A battery unit 30 comprises: a calculation unit 31 that applies AC signals to a positive electrode terminal 14 and a negative electrode terminal 15 of the storage battery 10, and calculates a dielectric constant or a capacitor capacity on the basis of the response signals; and a temperature monitoring unit 32 that monitors the internal temperature of the storage battery 10 on the basis of the dielectric constant or the capacitor capacity which has been calculated by the calculation unit 31.
Power is supplied by use of resonance from a power transmission device (50) to the side of a power reception coil (31) that is magnetically coupled to a power transmission coil (51). In this case, in order that overcurrent does not flow through a resonant circuit (53) even if the resonant circuit is brought into an operation state in a state in which the power transmission coil and the power reception coil are not magnetically coupled to each other, the power transmission device supplies AC power from a main power supply device (70) to the resonant circuit including the power transmission coil that is magnetically coupled to the power reception coil provided in a power reception device (30) via power lines (NL1, NL2) and brings the resonant circuit into a resonant state when the power reception coil is close to the power transmission coil and into a non-resonant state when the power reception coil is not close to the power transmission coil. Furthermore, when detecting an abnormality associated with the supply of power to the power reception device, the power lines are switched to a non-conduction state and the supply of AC power from the main power supply device to the resonant circuit is interrupted.
A torque command calculation unit (40) of a braking force control unit (400) calculates a torque command value (Trq*) for a motor (60) on the basis of required braking force commanded from the outside. The relationship between the torque of the motor (60) and braking force generated in electric brakes (81-84) has hysteresis characteristics. When the torque increases, the braking force increases along a positive efficiency line, and when the torque decreases, the braking force decreases along an inverse efficiency line. A specific controller (48) of the torque command calculation unit calculates the torque command value (Trq*) so that the actual load is caused to approach a load command value or the actual position is caused to approach a position command value. A control adjuster (471, 472, 473) adjusts parameters of the specific controller (48), or of control calculation at the input side or output side of the specific controller (48), during an increasing operation, a decreasing operation, or a transition between the increasing operation and the decreasing operation.
