ABSTRACT

With the emergence of a large number of smart mobile products, it has brought great convenience to our life. However, at present, the battery power of mobile devices cannot provide longer endurance to the equipment, so portable power supply came into being. According to the structure characteristics and working principle of mobile power source, this paper proposes a mobile power supply design scheme with high power conversion efficiency and low power consumption. It gives the hardware circuit design and software process, hardware object debugging, and has very strong practical application value.

Keywords: Polymer lithium battery, Single-chip microcontroller, Mobile power supply, Charging circuit, DC-DC boost circuit
