This invention offers an battery system that reduces a conversion loss due to a charger to reduce power consumption. The battery system has a solar battery, a battery module, a bypass route to bypass a charger to charge the battery module with DC power generated by the solar battery, and a control unit to control so that the electric power generated by the solar battery is supplied to the battery module through the bypass route when an output voltage of the solar battery is equal to or higher than a first predetermined voltage, that is higher than a terminal voltage of the battery module, and equal to or lower than a second predetermined voltage.

Battery system

A battery system including an assembled battery, a charge mode for charging the assembled battery and a discharge mode for converting electric energy charged in the assembled battery to AC power having the same or substantially the same frequency as a grid and supplying the AC power to a power supply line through which the grid and a load are connected further including a current detector for detecting current supplied to the load, and a control device for calculating an average power usage of past several days based on current being detected by the current detector, and converting the amount of electric power corresponding to the difference between the average power usage and a power usage based on the current value from the current detector to the AC power from the assembled battery to the load in the discharge mode to supply the AC power to the power supply line.

An air conditioner for exchanging heat from a refrigerant to the outside and adjusting at least one of room temperature and humidity to desired temperature and humidity and having a 1/f fluctuation function for controlling an air supplying means for supplying conditioned air to the room so as to vary the air supplying amount in multiple levels corresponding to a designated reference air amount and irregularly. A reference air amount of the air supplying means can be designated and there is an air amount control for controlling the air supplying means corresponding to the designated reference air amount, and a fluctuation width designates a fluctuation width (volume of the air amount) corresponding to the air amount designated. When the 1/f fluctuation function is employed, the fundamental functions (coolness, warmness, and so forth) of the air conditioner are improved. In addition, the noise of the air conditioner is reduced and the comfort of the user is improved.
