摘要： The present invention pertains to the detection of the state of charge of a battery, whereby the complex impedance in the diffusion region of the battery is used. An arithmetic device such as a computer determines the slope of the complex impedance at least two different frequencies in the diffusion region of a rechargeable battery when a straight-line approximation has been made. The state of charge of the rechargeable battery is detected by using the slope that has been determined, and the relationship between the state of charge and slopes that have been stored in advance in a storage means.

摘要： This device and method use the complex impedance of a rechargeable battery to detect the state of the rechargeable battery. A computer determines the slope of the complex impedance at least two different frequencies in a diffusion region of the rechargeable battery when a straight-line approximation has been made, and compares the slope with a threshold value. If the slope is greater than or equal to the threshold value, the computer determines that the battery has a normal capacity balance, and if the slope is less than the threshold value, the computer determines that the battery has an abnormal unbalanced capacity. Furthermore, if the magnitude of an imaginary axis component of the complex impedance in the diffusion region of the rechargeable battery is greater than the threshold battery, the computer determines that the battery has an abnormal capacity balance, and if said magnitude is less than or equal to the threshold value, the computer determines that the battery has a normal capacity balance.

摘要： A manager that lessens a difference in state of charge of a battery pack. The battery pack is constituted of a plurality of blocks. A slave unit is provided for each of the blocks, to thus detect a terminal voltage of the block and supply the detected terminal voltage to a master unit. A difference arises in state of charge among the blocks for reasons of a difference in current consumption of the respective slave units. The master unit makes up an operation clock signal for each of the slave units from a high frequency signal and a low frequency signal. A difference in state of charge among the blocks is lessened by controlling an appearance ratio of the high frequency signal to the low frequency signal for each of the slave units.

摘要： A battery system includes a nickel-metal hydride battery and an ECU that controls charging and discharging of the nickel-metal hydride battery. The ECU calculates a discharge electricity amount showing an integrated value of a current discharged from the nickel-metal hydride battery, and further calculates ΔSOC of the nickel-metal hydride battery in a prescribed time period. The ECU calculates a charge reserve capacity of the nickel-metal hydride battery based on a temperature of the nickel-metal hydride battery, the discharge electricity amount, and the ΔSOC.

摘要： A laser welding device that laser-welds a lid to an open portion of a casing emits a laser beam to a joining subject portion including an inner side surface of the casing that defines the open portion and a peripheral surface of the lid that faces the inner side surface of the casing. The inner side surface of the casing and the peripheral surface of the lid are arranged to form a groove in between, and include inclined surfaces that function as a sliding portion. The groove portion has a groove width that is variable by sliding the sliding portion. A detection unit detects the groove width of the groove portion. An adjustment force application unit applies force for adjusting the groove width to the casing. A control unit controls the force applied by the adjustment force application unit in accordance with the groove width detected by the detection unit.

摘要： A battery state determination device, which determines a micro-short-circuiting tendency state, includes an impedance meter that applies an AC voltage or an AC current of a measurement frequency to a rechargeable battery, which is subject to determination, and measures complex impedance. The device further includes a detector that detects an absolute value of an imaginary axis component of the complex impedance. The device further includes a determiner that compares the absolute value of the imaginary axis component detected by the detector with a lower limit threshold value. The lower limit threshold value is set based on a measurement result of the absolute value of the imaginary axis component of the rechargeable battery in the micro-short-circuiting tendency state. When the absolute value of the imaginary axis component is smaller than the lower limit threshold value, the determiner determines that the rechargeable battery is in the micro-short-circuiting tendency state.
