Title:
DC-DC CONVERTER FOR SOLAR-RELATED ENERGY STORAGE SYSTEM, AND CONTROL METHOD THEREOF
Document Type and Number:
WIPO Patent Application WO/2019/231047
Kind Code:
A1
Abstract:
One embodiment discloses a DC-DC converter which, in a solar-related energy storage system, cuts-off the over-discharging of a battery, and a control method thereof. Specifically, disclosed are a DC-DC converter which protects a battery by appropriately switching between a sleep mode which minimizes battery consumption by maintaining only minimized functions and a cut-off mode which prevents the battery from over-discharging by physically cutting-off a circuit connected to the battery, and a control method thereof. Also, an embodiment discloses a DC-DC converter or reverse wiring protection device for between a solar panel and a battery. Specifically, disclosed is a DC-DC converter or reverse wiring protection device comprising: a reverse current pass circuit comprising a current sensor, a voltage sensor, a diode and a fuse; a breaker circuit which cuts-off the supply of power if reverse wiring is sensed by the current sensor or the voltage sensor; a capacitor which is connected in parallel to the reverse current pass circuit; and a switch which connects the reverse current pass circuit and the battery pack.
