Title:
TRICKLE CHARGING POWER SUPPLY SYSTEM
Document Type and Number:
WIPO Patent Application WO/2017/212815
Kind Code:
A1
Abstract:
The present invention relates to a trickle charging system, a power supply system and the like, and provides a technology that can realize a higher output and a larger current discharge from a storage battery during an electrical outage than were previously possible. Provided is a trickle charging power supply system that comprises: a storage battery unit 3 that includes a nickel-zinc battery as a storage battery 30; a commercial power network; a load 2; and a charging power supply 1 that is connected to the storage battery unit 3. The trickle charging power supply system trickle charges the storage battery 30 from the charging power supply 1 as a state where the storage battery 30 is not connected to the load 2 during a normal time, and supplies direct-current power to the load 2 via a discharge from the storage battery 30 as a state in which the storage battery 30 is connected to the load 2 during a power outage. The storage battery 30 operates in an SOC range of 95-100% in the case where a fully charged state is 100%. A trickle charging voltage of trickle charging is a constant voltage within a range of 1.82-1.86 V. A maximum current of a trickle charging current is 1C.
