Problems solved by technology

[0003] For existing mobile terminals that use single-port rechargeable batteries, the charging system and power consumption system need to be discharged or charged from the same port on the rechargeable battery. Considering the principle of the shortest current path, the charging system and power consumption system (load) can only be placed on the mobile terminal. The same position of the terminal, so that the mobile terminal layout is limited
When the charging system and power consumption system are placed in the same position of the mobile terminal, the distance between the two heat sources of the charging system and the power consumption system is very close, so that the heat problem of the mobile terminal cannot be effectively solved. Furthermore, due to the layout limitation of the mobile terminal, the The charging current cannot be further increased

Abstract

The invention provides a dual-port charging battery and a charging system thereof. The charging system comprises a charging battery internally provided with an electrical core, a charging control circuit, a discharging control circuit, a first pathway and a second pathway, wherein the charging battery is provided with a charging port and a discharging port which are connected with the electrical core inside the charging battery; the charging port is connected with the charging control circuit through the first pathway, and the charging control circuit is used for connection with a power supply for charging the charging battery; and the discharging port is connected with the discharging control circuit, and the discharging control circuit is connected with a load through the second pathway for supplying power to the load. According to the dual-port charging battery and the charging system thereof, provided by the invention, the charging battery is not charged and discharged on the same port, layouts of the charging system and the load are not restricted, the problem of heat dissipation is solved, and charging currents of the charging battery are increased.

Description

Technical field [0001] The invention relates to the field of rechargeable batteries, in particular to a dual-port rechargeable battery and its charging system. Background technique [0002] The current charging system for mobile terminal rechargeable batteries uses a single port to charge the rechargeable battery inward, and the rechargeable battery uses the same port to supply power to the peripheral load when it supplies power to the peripheral load. (Such as figure 1 ) [0003] Existing mobile terminals using single-port rechargeable batteries, the charging system and the power consumption system need to discharge or charge from the same port on the rechargeable battery. Considering the principle of the shortest current path, the charging system and the power consumption system (load) can only be placed on the mobile The same location of the terminal limits the layout of the mobile terminal. When the charging system and the power consumption system are placed in the same posit...
