The invention particularly relates to a two-way battery power supply system based on a domestic Fei-Teng platform. The two-way battery power supply system based on the domestic Fei-Teng platform comprises two independent configurable battery ports, a main battery and a secondary battery; an embedded controller EC is connected with the main battery and the secondary battery through multi-way adaptors, and an interface of a charger is connected with the main battery and the secondary battery through a field effect transistor FET. According to the two-way battery power supply system based on the domestic Fei-Teng platform, the fast switchover of the main battery and the secondary battery can be achieved, the most stable power supply scheme can be selected according to the electricity consumption situation of equipment and the battery capacity, not only can the high-efficient and stable operation of the equipment be facilitated, but also the service life of the equipment, especially the batteries can be prolonged effectively, the competitiveness of the domestic Fei-Teng platform equipment is improved, and great convenience is supplied to life of people.
Description
technical field [0001] The invention relates to the technical field of power supply system design, in particular to a dual-way battery power supply system based on a domestic Feiteng platform. Background technique [0002] In recent years, mobile devices such as digital cameras, smartphones, and laptops have increasingly appeared in popular lives due to their portability and flexibility, and have gradually become an indispensable daily necessities. However, all mobile devices currently have a problem restricting their use and development, that is, the existing battery capacity cannot meet the needs of mobile devices. Although people have developed backup power devices such as charging treasures, in practical applications, the use of charging treasures is subject to many restrictions, and it still cannot meet people's growing demand for battery capacity. In this context, the dual power supply system came into being. [0003] BATT_ID is the abbreviation of address line, and ...
