Description

technical field [0001] The present invention relates to the technical field of power electronics, in particular to a method, device and electronic equipment for obtaining battery power. Background technique [0002] With the continuous development of power electronics technology, there are endless types of power electronics products. Among them, the vast majority of electronic products can use rechargeable batteries. Taking the rechargeable battery as a lithium battery as an example, the charging process of the completed lithium battery can be divided into three parts: trickle charging, constant current charging, and constant voltage charging. During the whole charging process, the charging voltage of the battery will be high. For example, the actual battery voltage is 3.6V, and the voltage displayed by the battery during charging may be 3.7V. During the actual use of the electronic device, for example, the electronic device is a mobile phone, a watch or a wristband, etc.,...
