Example Embodiment

[0135] By providing a power supply method and an electronic device, the embodiment of the present application solves the technical problem in the prior art that the adapter cannot be fully utilized, that is, the utilization rate is low, and achieves the technical effect of improving the adapter utilization rate.

[0136] The technical solution in the embodiment of the present application is to solve the above-mentioned technical problems, and the general idea is as follows:

[0137] In order to improve the utilization rate of the adapter, first, select an adapter whose rated power is smaller than the maximum power consumption of the electronic device, for example: when the maximum power consumption of the electronic device is 75W, select an adapter with a rated power of 60W.

[0138] Then, in the actual implementation process, the current power consumption value of the electronic device will be detected, and when the current power consumption value of the electronic device is l...

Abstract

The invention discloses a power supply method and an electronic device. The power supply method is applied to the electronic device comprising a power battery. The electronic device further comprises an adapter interface; an adapter having a first power rated can power the electronic device through the adapter interface; maximum power consumed by the electronic device is second power; the second power is higher than the first power. The power supply method includes: at a first moment, detecting a first current power consumption value of the electronic device; judging whether the first current power consumption value is greater than the first power or not so as to obtain first judgment results; if the first judgment results indicate that the first current power consumption value is greater than the first power, controlling the power battery to be in a charging state, and powering the electronic device through both the power battery and the adapter.

Description

technical field [0001] The invention relates to power supply technology in electronic technology, in particular to a power supply method and an electronic device. Background technique [0002] With the development of electronic equipment, users have higher and higher requirements on the performance of electronic equipment. Normal power supply to electronic equipment is necessary for electronic equipment to achieve all its performances. Therefore, how to safely provide sufficient power to electronic equipment to enable electronic equipment to achieve its performance has become a research hotspot. [0003] In the prior art, an adapter with a rated power higher than the maximum power consumption of the electronic device is usually used to supply power to the electronic device. For example, when the maximum power consumption of an electronic device is 60W, an adapter with a rated power of 90W is selected to power the electronic device. powered by. In this way, when the electro...
