摘要:
A technology described herein is for accurately determining the SOC of a secondary battery. An open-circuit-voltage-to-state-of-charge (OCV-SOC) characteristic has a capacity decrease estimation OCV region in which a relationship between the OCV and the SOC is assumed not to change due to degradation of the secondary battery 1a since a reference time point. Charge currents or discharge currents in the capacity decrease estimation OCV region are accumulated in a process in which the secondary battery SOC changes among OCVs. From the accumulation, an accumulated current is obtained. A secondary battery capacity decrease is estimated based on the accumulated current. An OCV-SOC characteristic is specified based on the estimated secondary battery capacity decrease and a predetermined relationship between the battery capacity decrease of the secondary battery since the reference time point and the OCV-SOC characteristic. A secondary battery SOC is determined based on the OCV and the specified OCV-SOC characteristic.

A permanent magnet rotor has a rotor core positioned about a rotation shaft. The permanent magnet rotor also has permanent magnet embedment slots located at equally spaced positions from the rotation shaft, with permanent magnets inserted into each of the respective permanent magnet embedment slots. The permanent magnet embedment slots each have both a magnet storing portion, and a buffer and other members storing portion which extends to the magnet storing portion. Once a permanent magnet is stored inside the magnet storing portion, a buffer member, and a pushing member are used to secure the permanent magnet inside the rotor core.

A trace guide (TG) that has been set within a manual trace reference cross-section (58) is illustrated with a dashed line. The trace guide (TG) is obtained from three-dimensional contour information based on already-completed manual tracing of a first sheet. Therefore, the user draws a trace line (TL) corresponding to the contour of target tissue on a second sheet of the manual trace reference cross-section (58) while referring to the trace guide (TG) and also checking a tomographic image of the target tissue within the manual trace reference cross-section (58). The user may: draw the trace line (TL) in full; use apart of the trace guide (TG) without alteration as the trace line (TL) and correct the remaining part to serve as the trace line (TL); or use the trace guide (TG) without alteration as the trace line (TL).

A condition determination device for determining a condition of an electric storage device includes a current detector, a voltage detector, and a controller. The controller is configured to: determine a level of a first electric factor based on at least one of a charging current detected by the current detector and a charging voltage detected by the voltage detector; obtain first charging time while the level of the first electric factor is constant; determine a level of a second electric factor based on the charging voltage detected by the voltage detector; obtain second charging time while the level of the second electric factor is constant; calculate a determination value based on the first charging time and the second charging time; and determine a condition of the electric storage device based on the determination value.
