The embodiment of the invention provides a battery energy-saving circuit. The battery energy-saving circuit comprises a control signal input module, a system control module, a voltage conversion module, a control switch detection module and a system driving module; when the control switch is triggered, the control signal input module outputs a first voltage; the system control module enables the battery to be electrically connected with the voltage conversion module; the voltage conversion module outputs a second voltage; when the control switch is triggered, the control switch detection module outputs a third voltage; and when the control chip receives the second voltage and the third voltage, the system control module enables the battery to be electrically connected with the voltage conversion module. The embodiment of the invention also provides electronic equipment comprising the battery energy-saving circuit. Therefore, according to the battery energy-saving circuit and the electronic equipment provided by the embodiment of the invention, the energy consumption of the battery can be saved.
Description
technical field [0001] The present application relates to the field of battery technology, in particular to a battery energy-saving circuit and electronic equipment. Background technique [0002] With the rapid development of consumer electronics, the application of lithium-ion batteries is also increasing. At present, lithium-ion batteries have been widely used in electric equipment such as mobile phones, digital cameras, electric vehicles, vacuum cleaners, sweeping robots, and drones. [0003] In the prior art, a control switch is usually used to control a micro control unit (Micro Controller Unit, MCU) to perform operations such as turning on or disconnecting the battery. , the microcontroller unit can still communicate with the battery, thereby increasing battery power consumption. Contents of the invention [0004] In view of the above problems, the embodiments of the present application provide a battery energy-saving circuit and electronic equipment, which cut off...
