摘要： A battery unit includes: a module including m cell groups that are connected in series and each include n cells connected in parallel; m voltage detectors; (m×(n−1)) heat flow detectors; a storage; and a state estimator. The storage stores a table map of OCV vs. SOC characteristics (A1) and a table map of HF vs. SOC characteristics (A2). For each of the m cell groups, the state estimator is configured to: determine, based on the (A2), a true SOC of (n−1) cells that corresponds to a heat flow detected; determine, based on the (A1), an OCV of the (n−1) cells that corresponds to the determined true SOC; calculates an OCV of a remaining cell from the determined OCV and a detected composite voltage; and determine, based on the (A1), a true SOC of the remaining cell that corresponds to the calculated OCV.

摘要： To reduce influence of external force on a current collection tab lead and a current collection tab in a laminated cell type battery. A single film of an exterior body contacts and covers a top surface, a bottom surface, and two side surfaces of a battery perpendicular to an end surface of the battery from which a current collection tab and a current collection tab lead are provided to extend, covers the end surface of the battery from which the current collection tab and the current collection tab lead protrude, and is folded in from both short sides of the end surface such that triangular pyramid-shaped spaces are formed on both sides. A reinforcement member is arranged in and joined to each triangular pyramid-shaped space.
