Component having multiple output voltages and electronic device using same

Abstract

The invention provides a component having multiple output voltages and an electronic device using the same. The component having multiple output voltages comprises a battery body, a plurality of battery units arranged in the battery body, and a power management unit, wherein, the battery units are used for outputting various supply voltages to a plurality of electronic components in an electronicdevice respectively; and the power management unit is electrically connected with the battery units and used for converting external voltages into a plurality of charging voltages and correspondinglyoutputting the charging voltages to the battery units respectively to charge the battery units, wherein, the size of the charging voltage is equal to the size of the supply voltage.

Description

technical field [0001] The present invention relates to a component, and in particular to a component with multiple output voltages and an electronic device using the same. Background technique [0002] Today's portable products, such as communication phones, walkmans, digital cameras, notebook computers, etc., use batteries with a single voltage output, and their charging and discharging time and life are standard. Taking a general notebook computer as an example, the way to use the battery is to use a transformer to receive an AC voltage of 100 to 240V, and then convert it through an AC / DC converter to output a DC voltage of 10 to 32V (usually 18.5V or 19.5V) to the battery, which supplies a single voltage to the laptop. [0003] However, since the voltages required by the various units and chips inside the notebook computer are not the same, after the battery outputs a single voltage, it must be converted before it can be supplied to these units and chips, resulting in a...

Problems solved by technology

[0003] However, since the voltages required by the various units and chips inside the notebook computer are not the same, after the battery outputs a single voltage, it must be converted before it can be supplied to these units and chips, resulting in a waste of voltage conversion.

Moreover, under the current trend of thinner and thinner notebook computers, the battery volume is also getting smaller and smaller, which will affect the power supply time of the battery. Therefore, how to extend the battery life is also a problem worth exploring.
