Title:
POWER SUPPLY SYSTEM
Document Type and Number:
Japanese Patent JP2022177550
Kind Code:
A
Abstract:
To provide a power supply system capable of confirming an accumulator battery available time with ease.SOLUTION: A control unit 11a of a power conditioner 11, in an autonomous operation mode, calculates an accumulator battery available time on the basis of a power storage amount (an accumulator battery residual quantity) of an accumulator battery 11b. The control unit 11a determines whether a power supply of a load connected with the power conditioner 11 is turned on or off and sets load detection information. A control unit 61 of a controller 60 determines whether or not there is a change in load amount (power consumption) in the power conditioner 11 on the basis of the load detection information acquired from the power conditioner 11. When there is a change in load amount, the control unit 61 displays on a display unit 63 the accumulator battery available time in the power conditioner whose load amount is changed.SELECTED DRAWING: Figure 3
