摘要： PROBLEM TO BE SOLVED: To accurately determine an excessive charge situation of a secondary battery formed of a plurality of battery cells at an early stage while attaining the low cost and compactness of a battery device.
SOLUTION: The monitoring-target cell 55x as a part of the plurality of battery cells 55 is formed so as to increase cell internal pressure at an early stage in comparison with the other normal battery cell 55 at the time of an excessive charge state of a battery 51 by adding a designated additive to an electrolyte, and a pressure sensor 56 for detecting cell internal pressure Pcell is arranged at the monitoring-target cell 55x. Then, in the battery device 50, it is determined that the battery 51 is in an excessive charge state when the cell internal pressure Pcell detected by the pressure sensor 56 continuously exceeds reference pressure Pref.

摘要： PROBLEM TO BE SOLVED: To prevent the deterioration of battery performance beforehand and surely by detecting the proceeding of the deterioration of a secondary battery, based on the estimated electrolytic ion concentration between electrodes.
SOLUTION: A concentration change rate estimator 210 estimates the change rate ΔB of the concentration of an electrolyte, based on a charge/discharge current Ib, in use of a secondary battery. A concentration estimate calculator 230 calculates the estimates B# of the concentration of the electrolyte in use of the secondary battery, according to the estimated rate ΔB of change. A judgement part 250 judges whether the concentration of the electrolyte is within a normal range or not, based on the estimated estimate B# of the concentration of the electrolyte.

摘要： PROBLEM TO BE SOLVED: To make a secondary battery to be in an adequate temperature range while detecting an abnormality of a cooling device. SOLUTION: When a deviation ΔT between a presumed temperature Te calculated from a charge/discharge electricity current and a cooling performance of a secondary battery and an actual cell temperature Tb, is larger than a threshold Tr (S100 to S106), a fan for cooling is driven in Hi mode at first (S112), and an unusual rise of the temperature of the secondary battery is suppressed. When the deviation ΔT is larger than the threshold Tr (S110), even if the state where the fan for cooling is driven in Hi mode is progressed at a predetermined time, abnormalities are outputted (S116) by judging that a certain abnormality occurs in the cooling function of the device. Consequently, while being able to inhibit the unusual temperature rise of the secondary battery, certain abnormalities to the cooling function of the device can be detected more appropriately.
