Title:
BATTERY CHARGING AND DISCHARGING CONTROL CIRCUIT AND BATTERY CHARGING AND DISCHARGING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2017/020782
Kind Code:
A1
Abstract:
A battery charging and discharging control circuit and a battery charging and discharging system. The battery charging and discharging control circuit comprises: a switch control component (22), a MOS transistor circuit (24), and a first resistor providing a conduction voltage to the MOS transistor circuit (24). The switch control component (22) is connected to the MOS transistor circuit (24), and configured to control switching on or off of a first MOS transistor (VT1) and a second MOS transistor (VT2) in the MOS transistor circuit (24). The MOS transistor circuit (24) comprises the first MOS transistor (VT1) and the second MOS transistor (VT2). The first MOS transistor (VT1) comprises two output pins respectively connected to two terminals of the first resistor (26), and one output pin connected to a ground. The second MOS transistor (VT2) comprises two output pins respectively connected to the two terminals of the first resistor (26), and one output pin connected to a battery. The first resistor (26) is connected to the switch control component (22). The battery charging and discharging control circuit and the battery charging and discharging system can realize control over charging and discharging of a backup battery.
