Power supply device applied to portable devices

Abstract

The invention provides a power supply device applied to portable equipment. The power supply device at least comprises an adapter; the adapter at least comprises an electrical source controller B, a systematic management bus host and an interface; the electrical source controller B is used to receive the parameter collected by the systematic management bus host and control the charging current of the adapter according to the parameter; the interface is used for connecting the adapter and the electrical source controller A in the portable equipment and inputting the output current of the adapter to the electrical source controller A. By applying the technology of the invention, the battery and the adapter can be connected while shutdown is not needed; and the interfaces of the adapter and the battery are unanimous, when applied in the portable equipment with high power consumption, the supplied electrical power can be increased by concatenation; the battery and the adapter can be turned over to lead the bottom of the portable equipment to be higher, thus facilitating the effect of better heat emission. Meanwhile, the adapter controls one or a plurality of batteries to charge by the built-in electrical source controller.

Description

technical field [0001] The present invention relates to portable equipment power supply technology, in particular to a power supply device applied to portable equipment. Background technique [0002] The battery of a portable device (such as a notebook computer) is generally installed in the host, and an AC power adapter is configured outside the host, and the adapter with a dull color and shape often affects the appearance of the portable device; , being entangled affects the convenience of using the portable device. [0003] When a portable device is used in a home or office, it is usually necessary to take out the battery it carries, because the long-term floating charge of the battery will shorten the battery life; and because the battery has the function of supporting and balancing the weight of the device function, or itself is a part of the structure of the portable device, such as the battery in the handle of the portable device, etc., so if the battery is taken out...

AI Technical Summary

Problems solved by technology

[0006] The purpose of the present invention is to provide a power supply device applied to portable equipment, which is used to solve the problem in the prior art that the battery life is shortened due to excessive floating charging of the battery by the adapter, and unplugging the battery will cause disadvantages to the balance of the portable equipment. impact, and the way of using batteries to power portable devices is not flexible enough, and existing portable devices have defects such as poor heat dissipation
