A power supply system is provided that can reduce the maximum value of the amount of power per unit time supplied to a load and a power storage portion and that can increase the amount of power stored in the power storage portion. The power supply system (1) includes the power storage portion (11) and a charge-discharge control portion (51) that controls the charge and discharge of the power storage portion (11). The power supply system (1) supplies power to an EV charge portion (311) that is one of power storage portions (31). The charge-discharge control portion (51) charges the power storage portion (11) when a power or a current consumed by the EV charge portion (311) is equal to or less than a predetermined magnitude.

A recharging system that recharges batteries is provided with a recharging unit that recharges the batteries by consuming power that is supplied. The recharging unit has the ability to recharge the batteries by consuming system power supplied by a power company. The power company sets power rates that are higher the larger the maximum amount of power supplied per unit of time, and a single charge performed by the recharging unit begins in the preceding unit of time among adjacent units of time, and finished in the following unit of time among the adjacent units of time.

[Problem] To provide a charging system that levels the amount of grid power that is used, and that is capable of reducing power rates, even if charging has been frequently conducted without limiting the time zones in which charging is conducted. [Solution] A charging system is provided with: a storage unit that is charged by consuming grid power supplied by a power company, and that supplies the stored power through discharge; and a charging unit that charges batteries by consuming power supplied by grid power and the storage unit. Power companies set a power rate that is higher the greater the maximum value of the amount of power supplied for each unit of time is. Furthermore, at least a single charge carried out by the charging unit is carried out over two units of time, and the storage unit supplies power to the charging unit in at least one unit of time other than said two units of time.

An acquisition unit acquires state of health of a storage battery provided to supply electric power, in which the state of health shows a smaller value as the storage battery deteriorates. A display unit performs notification when state of health acquired by the acquisition unit is smaller than a first threshold value. When the acquisition unit has not acquired state of health for a predetermined period, the display unit performs notification if the elapsed period from the manufacture of the storage battery is longer than a second threshold value.
摘要:
The present invention relates to a process for producing a water-based pigment dispersion which includes a first step of mixing (A) an emulsion composition including a water-insoluble polymer having a specific weight-average molecular weight and containing a salt-forming group, an organic solvent having a specific solubility in water, a neutralizing agent and water, with (B) a pigment to obtain a preliminary dispersion having a content of non-volatile components of from 5 to 50% by weight and a weight ratio of the organic solvent to water [organic solvent/water] of from 0.1 to 0.9; a second step of continuously dispersing the preliminary dispersion by using a media-type dispersing device and continuously separating the resultant dispersion from media particles; and a third step of further dispersing the resultant dispersion by using a homogenizer, as well as a water-based ink for ink-jet printing containing the water-based pigment dispersion which not only satisfies a high optical density but also exhibits excellent gloss and rubbing resistance.
