The invention discloses a control circuit and electronic equipment, and belongs to the technical field of electronic equipment. The circuit comprises a load, a battery, a control module, a first capacitor and a boosting module. the battery is connected with the load, the boosting module is respectively connected with the battery and the first capacitor, the control module is respectively connected with the battery, the load, the first capacitor and the boosting module, and the control module is used for detecting the working temperature and the battery voltage of the electronic equipment; wherein under the condition that the working temperature is smaller than a first threshold value, the control module controls the battery and the boosting module to charge the first capacitor when the battery voltage is larger than or equal to reference voltage, and when the battery voltage is reduced to be smaller than the reference voltage, the control module controls the first capacitor to supply power to the load.
Description
technical field [0001] The application belongs to the technical field of electronic equipment, and in particular relates to a control circuit and electronic equipment. Background technique [0002] A lithium-ion battery is a rechargeable battery that primarily relies on the movement of lithium ions between positive and negative electrodes to function. During the working process of the lithium-ion battery, the internal resistance of the lithium-ion battery will be affected by the ambient temperature. In a low-temperature environment, the diffusion rate of ions and the electrochemical reaction slow down, resulting in a sharp increase in the internal resistance of the lithium-ion battery, an increase in the voltage drop of the lithium-ion battery, and electronic equipment is prone to problems such as abnormal shutdown or crash. Contents of the invention [0003] The purpose of the embodiments of the present application is to provide a control circuit and electronic equipment...
