摘要： A battery system having a battery string configured by connecting in series a plurality of battery units includes: an SOC detection unit for individually detecting states of charge of the plurality of battery units; and a charge-and-discharge control unit for individually charging and discharging the battery units, based on a full charge capacity of each battery unit and each state of charge of the battery units individually detected by the detection unit, upon the battery system being in no load state, the control unit individually charges and discharges the battery units so that the states of charge of the battery units are approximately equal with each other when the battery units are in a discharge end state and so that a difference between the states of charge of the battery units is relatively large when the battery units are approximately in a full charge state.

摘要： A lithium-ion rechargeable battery module having a plurality of lithium-ion battery cells, arranged that battery cells located at an high temperature portion of the module are electrically connected in parallel with battery cells located at a low temperature portion of the module. The battery cells at the high temperature portion have a higher electric resistance at 20° C. and a better high-temperature storage characteristic at 50° C. than those of the battery cells located at the low temperature portion.

摘要： A positive-electrode material for a lithium ion battery includes two or more types of positive-electrode active materials which are expressed by a chemical formula LiMPO4 (where M includes one or more types of metal elements selected from the group consisting of Mn, Fe, Co, and Ni) and which have an olivine structure. The M in at least one of the positive-electrode active materials includes two or more types of metal elements. An open circuit voltage curve in charging includes an initial rising region, one or more flat regions, one or more detectable voltage varying regions, and a terminal rising region in a state-of-charge region of 0% to 100%.
