Abstract: PROBLEM TO BE SOLVED: To extend an operating temperature range of a secondary battery while protecting the secondary battery.
SOLUTION: An integrated power overtime value tad is calculated by integrating a power overtime tov, i.e., the time when the charging power of a battery 26 exceeds an input limit Win and the time when the discharge power exceeds an output limit Wout, while weighting it in accordance with the battery temperature Tb. When the integrated power overtime value tad is equal to or below a predetermined time tref, the upper limit temperature Tmax of the battery 26 is set to the first temperature T1. When the integrated power overtime value tad exceeds the predetermined time tref, the upper limit temperature Tmax is reduced from the first temperature T1 as the integrated power overtime value tad increases, and is set to converge on the second temperature T2 which is lower than the first temperature T1.

Abstract: PROBLEM TO BE SOLVED: To provide an assembled battery system for an electric motor car, with a simple structure, in which even if electrolyte solution, leaks out of the battery in mist form it is prevented from flowing out from an exhaust passage. SOLUTION: An assembled battery case 5 containing assembled cells are set behind a rear seat 2 inside a cabin 1. An exhaust duct 7 equipped with a cooling fan 6 is connected to the cell case 5. An air intake hole 3 is provided on the opposite side of the exhaust duct connection part of the cell case. As a cooling fan 6, a soirocco fan or an axial fan is used. Then, air for cooling the assembled battery by force is made to flow through the cabin 1, the air intake hole 3, the assembled battery case 5, the exhaust duct 7, the cooling fan 6 and the exhaust duct 7 in that order, and, together with air, the mist-form electrolyte solution liberated from the cells is made to collide with, and adhered to, blade or wall face of the cooling fan 6.

Abstract: PROBLEM TO BE SOLVED: To prevent deterioration in reliability of set cells through early detection of cell block, corresponding to single battery having pin holes and cracks. SOLUTION: A means for detecting defective cells 12 determines a cell, having great internal resistance, when overcharging after an abnormal cell has been detected, that is, the difference in voltage change from the voltage change of normal cells, when overcharging is larger than the constant obtained from cell characteristics, as a leakage defective cell, and determines a cell, of which the internal resistance does not increase, when overcharging as a slightly short-circuited cell. The reason is that in leakage defective cells, the cell voltage is larger when charging, because internal resistance rises, while cell voltage is smaller, when discharging; and in a slightly short-circuited cell, because of its reduction in capacity, the cell voltage is smaller, when discharging but is not larger when charging.

Abstract: PROBLEM TO BE SOLVED: To prevent the internal pressure rise of a battery set, when uniformly recharging each electric cell of the battery set. SOLUTION: This method of recharging a battery set includes a plurality of single batteries and a first process of charging each single battery at first rate by first current, until the internal pressure of at least one electric cell out of a plurality of electric cells beings to rise, and a second process of recharging or discharging each electric cell at a second rate which is lower than the first rate by second current lower than the first current. When recharging each electric cell uniformly in a battery set, where a plurality of single batteries are combined, it is recharged with a fixed current, until the surviving capacity (SOC) of the battery becomes 100%, and then it is recharged with a current at low rate.
