Abstract: Fabric cleansing articles and methods for cleansing hair and/or skin can comprise a cleansing article including a body made from non-woven fabric, where the body has a first side and a second side opposite the first side and a thickness less than a length and a width thereof. A first group of first projections extends from the first side of the body, and a second group of second projections extends from the first side of the body. A largest width of the first projections of the first group is greater than a largest width of the second projections of the second group, and a height of the first projections of the first group is greater than a height of the second projections of the second group. A backside of the first projections and/or the second projections may be hollow or concave.

Abstract: A storage battery system control method includes at least the following steps. Respective current SOC (state of charge) values of the large capacity storage battery system and the high power storage battery system are acquired. Electrical power, which is required to operate the frequency control service for the purpose of suppressing frequency fluctuations, to the large capacity storage battery system and the high power storage battery system, in accordance with the respective SOC values. The respectively allocated electrical power is charged or discharged by driving the large capacity storage battery system, or alternatively, the high power storage battery system, or alternatively, the large capacity storage battery system and the high power storage battery system.

Abstract: A controller (130) reads out a voltage value correlated with the ambient temperature of a battery (200) measured by a temperature measurer (110) from a storage device (120), so that a charger (140) charges the battery (200) at the voltage value read out by the controller (130).

Abstract: Remaining capacity calculation section (110) calculates remaining capacities for each of cells (300-1) and (300-2) connected in parallel with each other, and control section (130) discharges one of cells (300-1) and (300-2) having priority until the remaining capacity of that cell becomes equal to a second threshold value stored in storage section (120), if the remaining capacity of the one of the cells calculated by remaining capacity calculation section (110) is equal to a first threshold value stored in storage section (120).

Abstract: A battery sensing section measures a voltage across a secondary battery. A current sensing section measures a current flowing through the secondary battery. A control section holds the value of an external impedance present in a discharge path outside the secondary battery, discharges the secondary battery from a first time to a second time at which an integrated discharge capacity based on a measured discharge current becomes equal to a predetermined discharge capacity reference value, calculates the internal impedance present in the secondary battery at the second time based on the measured voltage, calculates the second open voltage at the second time by multiplying the sum of the external impedance and the internal impedance by the measured discharge current, and calculates the recovered capacity of the secondary battery based on the first open voltage at the first time, the second open voltage and the discharge capacity reference value.
