摘要： A state estimation apparatus disclosed in the present specification is a battery management unit estimating the state of an assembled battery including a plurality of energy storage devices. The energy storage devices each have a small-variation region II and a small-variation region IV where an OCV variation amount relative to a residual capacity is smaller, and a variation region I, a variation region III, and a variation region V where the OCV variation amount relative to the residual capacity is greater than that in the small-variation region II and the small-variation region IV. The battery management unit estimates whether or not the assembled battery is usable based on a varying position (a variation in position from a first position to a second position) of the variation region III relative to the actual capacity of the plurality of energy storage devices.

摘要： Lower order control devices (IC-1, IC-2, IC-3) control plural battery cells (VB1, ..., VB12) configuring plural battery modules. An input terminal (In) of the low order control device (IC-1) in the highest potential, an output terminal (Out) of the low order control device (IC-3) in the lowest potential, and a high order control device (MPU) are connected by isolating units, photocouplers (F1, ..., F6). Diodes (D2, D4, ZD4) which prevent a discharge current of the battery cells in the battery modules are disposed between the output terminal of the low order control device and the battery cells in the battery module on the low potential side. Terminals related to input/output of a signal are electrically connected without isolating among the plural low order control devices.
