Title:
COMPLEX POWER SOURCE
Document Type and Number:
WIPO Patent Application WO/2020/017052
Kind Code:
A1
Abstract:
Provided is a complex power source for making it possible to prevent an erroneous operation of an electronic device connected to a main power source and for making it possible to deal with a sudden fluctuation of power demand or power supply. A complex power source 10a has a main power source 12a, an auxiliary power source 14a, and an opening/closing switch 16a. The main power source 12a is one selected from the group consisting of fuel batteries, air batteries, secondary batteries, primary batteries, and complex batteries obtained by connecting at least two of these batteries with each other, and is constantly connected to a load 18. The auxiliary power source 14a is a secondary battery having an output power capacity greater than that of the main power source 12a and internal impedance lower than that of the main power source 12a, and is connected in parallel to the main power source 12a. The opening/closing switch 16a is connected in series to the auxiliary power source 14a, and is closed to start power supply from the auxiliary power source 14a to the load 18 when at least one of a predicted value of discharge current of the main power source 12a after a predetermined time period and a predicted value of discharge voltage of the main power source 12a after a predetermined time period, exceeds an allowable range because of generation of sudden large current discharge.
