Embodiment Construction

[0034] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in further detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

[0035] The present invention is a sine wave-like charging method capable of regularly adjusting the charging current value. In one embodiment, please refer to figure 1 As shown, the method is applied to a power supply device 1, the power supply device 1 includes a charging circuit 11, and the charging circuit 11 can be electrically connected to a rechargeable battery 21, so that the power supply device 1 passes through the charging circuit 11, The current is transmitted to the rechargeable battery 21. In particular, since the rechargeable battery 21 is assembled into an electronic product (such as: a smart phone, a tablet computer, etc.), as the type and design of the electronic product are different, The appearance of th...

Abstract

The invention provides a quasi sine wave charging method capable of regularly adjusting the charging current value. Multiple current values are transmitted when a rechargeable battery is charged by a charging circuit. The current values are continuously transmitted for a charging period and then transmission is stopped for an interruption period. The current values include a first current value, multiple attenuation current values, a second current value and multiple increasing current values in order according to the charging process, and the charging circuit repeats the transmission order of the current values, wherein the numerical values of the attenuation current values decrease in order and are less than the first current value and greater than the second current value, and the increasing current values increase in order and are greater than the second current value and less than the first current value so that the charging current changes along with time to form the quasi sine wave charging process.

Description

technical field [0001] The present invention relates to a charging method, in particular to a charging method in which a power supply device changes the value of its charging current over time to form a charging process similar to a sine wave. Background technique [0002] In recent years, with the vigorous development of electronic and communication technologies, mobile terminal devices (such as: mobile phones (mobile phones) and smart phones (smart phones)... etc.) not only have powerful communication functions, but also provide many services that can meet people's daily life. , Other application functions for work, social and entertainment, such as: notes, timing, counting, scheduling, lighting, photography, video, GPS, drawing, statistics, meeting, investment, withdrawal, shopping, ticket booking, seat reservation, meal ordering , chatting, socializing, games...the list goes on and on, and it has almost become an indispensable device for most urbanites, and a mobile phon...
