Power source management system and portable electronic device with same

Abstract

The invention relates to a power source management system which comprises a power source device, a detection module and an output power control module, wherein the power source device comprises a battery and a power source input module; the detection module comprises a charging control chip; the charging control chip is electrically connected with the battery, the power source input module and the output power control module; the charging control chip controls the charging current of the battery and detects the output current of the power source device; and the power source device corresponding to the charging control chip is also respectively provided with an over-current protection point, and when the current output by the power source device is detected to exceed the corresponding over-current protection point, the charging control chip can be used for reducing the charging current of the battery or the output power control module can be used for reducing the working frequency of the portable electronic device so as to reduce the output current of the battery or the power source input module. The invention also provides a portable electronic device with the power source management system.

Description

technical field [0001] The present invention relates to a power management system, in particular to a power management system for a portable electronic device such as a portable computer and a portable electronic device with the power management system. Background technique [0002] The power supply device of a portable electronic device such as a portable computer generally includes a battery and a power output module carried by itself, so that the portable computer can provide power through the battery, and can also be connected to an external power supply through the power input module. As people have higher and higher performance requirements for portable computers, the power required for the work of components such as the built-in core processor and display chip of the portable computer is also higher and higher, and when the hard disk and optical drive of the portable computer When components such as interfaces and interfaces are under heavy load conditions, the power ...
