Title:
FORWARD AND REVERSE BUCK-BOOST CHARGE-DISCHARGE CIRCUIT AND ELECTRIC TOOL
Document Type and Number:
WIPO Patent Application WO/2023/130668
Kind Code:
A1
Abstract:
The present application provides a forward and reverse buck-boost charge-discharge circuit and an electric tool. The forward and reverse buck-boost charge-discharge circuit comprises: a battery, a forward and reverse buck-boost charge-discharge unit, and a first control unit. The battery is used for storing power and supplying power to a load; the forward and reverse buck-boost charge-discharge unit is used for charging and discharging the battery; the first control unit is used for controlling the forward and reverse buck-boost charge-discharge unit to boost or reduce a voltage to supply power to the load, and controlling the forward and reverse buck-boost charge-discharge unit to charge the battery by means of external input voltage boost or voltage reduction. The battery is connected to the forward and reverse boost-buck charge-discharge unit, and the forward and reverse boost-buck charge-discharge unit is connected to the first control unit. According to the forward and reverse buck-boost charge-discharge circuit and the electric tool provided in embodiments of the present application, charging efficiency is improved.
