  • Publication number: 20210011087
    Abstract: A power storage device inspecting method of inspecting a power storage device for an internal short circuit includes: detecting an external resistance Re which is generated in an external circuit in a state in which probes of an external power supply are connected to external terminals of the power storage device; applying an initial output voltage VS(0) with which an initial device current IB(0) of a device current IB(t) is zero; applying an output voltage VS(t) expressed by Equation (1) from the external power supply to the power storage device; and determining an internal short circuit of the power storage device based on a change with time of the device current IB(t) or a stabilized device current IBs. VS(t)=VS(0)+(Re?Ro1)·IB(t)??(1) Here, a first virtual external resistance Ro1 is a constant satisfying 0<Ro1<Re.

  • Publication number: 20200106142
    Abstract: A battery manufacturing apparatus includes a binding member for bounding a battery stack and a fluid supplying part for blowing cooling fluid onto the bound battery stack. The binding member includes a first both-side part for bounding batteries from both sides by applying a load thereon in a first direction in which the batteries are arranged, and a second both-side part to be placed on both sides of the batteries to face both side surfaces of the batteries in a second direction different from the first direction. The binding member is formed with apertures through which the cooling fluid flows outward in the second direction. The fluid supplying part includes a first discharging part and a second discharging part for discharging the cooling fluid from both sides in a third direction different from both the first direction and the second direction toward the battery stack bound by the binding member.

  • Patent number: 8593137
    Abstract: An eddy current sensor that includes: a probe and a computing unit. The probe has an exciting portion and a detecting portion. The exciting portion includes a first excitation coil that is wound around a non-magnetic bobbin so that a center axis direction is oriented in an x-axis direction and a second excitation coil that is wound around the non-magnetic bobbin to intersect with the first excitation coil so that a center axis direction is oriented in a y-axis direction. The detecting portion includes a detection coil that is arranged at the lower one of two intersecting portions of the first excitation coil and the second excitation coil. An eddy current measurement method for determining the thickness of a hardened layer.
