Title:
PROTECTION CIRCUIT, BATTERY AND AIRCRAFT
Document Type and Number:
WIPO Patent Application WO/2020/135798
Kind Code:
A1
Abstract:
The present invention relates to the technical field of batteries, and discloses a protection circuit, a battery, and an aircraft. The protection circuit is used for monitoring a power supply circuit and comprises: a detection circuit, and a switch circuit connected to the detection circuit; when the detection circuit detects that the power supply circuit is abnormal, the detection circuit outputs a low level, so that the switch circuit is in a disconnected state so as to cut off a power supply loop. The protection circuit provided by embodiments of the present invention does not require a dedicated protection chip, and may effectively save costs; moreover, the protection circuit may adapt to different power supply demands by means of adjusting parameters of the detection circuit and switch circuit of the protection circuit, thereby effectively improving the adaptability and flexibility of protection.
