Title:
CHARGING CIRCUIT, TERMINAL, AND CHARGING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2018/054142
Kind Code:
A1
Abstract:
A charging circuit (10), a terminal, and a charging system. The charging circuit (10) is connected to a charger, a terminal load, and a battery, and comprises a first adjustment circuit (110), a current detection circuit (120), a voltage detection circuit (130), and a control circuit (140). A first end of the first adjustment circuit (110) is connected to the charger. A second end of the first adjustment circuit (110) is further connected to the terminal load. A third end of the first adjustment circuit (110) is connected to the control circuit (140). A second end of the current detection circuit (120) is connected to a positive electrode of the battery. A negative electrode of the battery is connected to the charger. The current detection circuit (120) is connected in series between the negative electrode of the battery and the charger. The charging circuit (10) can adjust the charging current when it suddenly increases so as to avoid the excessive charging current damaging the charging circuit (10) and the battery.
