Embodiment 1

[0041] see figure 1, the present embodiment provides a method for obtaining wattage information of a power adapter under an HPB charging chip architecture platform, including:

[0042] Step 101 , after the power adapter is connected to the system, apply a load to the system step by step according to a preset increase rate, so as to prompt the power adapter to discharge the system step by step. As the load increases, the step-by-step discharge process can be divided into multiple discharge stages corresponding to different load sizes, and the load corresponding to the previous discharge stage is smaller than the load in the latter discharge stage.

[0043] In this embodiment, after the EC confirms that the battery power in the system is greater than 80%, the CPU temperature is lower than 60 degrees, and the battery has no discharge current, the initial power adapter current limit setting in the charging chip is released, that is, the preset growth rate (such as 5%) apply loads...

Embodiment 2

[0065] see Figure 5 , the present embodiment provides a method for acquiring wattage information of a power adapter under an NVDC charging chip architecture platform, comprising steps:

[0066] Step 201 , after the power adapter is connected to the system, apply a load to the system step by step according to a preset increase rate, so as to prompt the power adapter to discharge the system step by step. As the load increases, the step-by-step discharge process can be divided into multiple discharge stages corresponding to different load sizes, and the load corresponding to the previous discharge stage is smaller than the load in the latter discharge stage.

[0067] In this embodiment, after the EC confirms that the battery power in the system is greater than 80%, the CPU temperature is lower than 60 degrees, and the battery has no discharge current, the initial power adapter current limit setting in the charging chip is released, that is, the preset growth rate (such as 5%) a...

Embodiment 3

[0077] Corresponding to the first embodiment, the third embodiment provides a power adapter wattage information acquisition device, which is suitable for the HPB charging chip architecture platform, including: EC and charging chip, and a step-by-step discharge control unit.

[0078] The step-by-step discharge control unit is used to apply loads to the system step by step according to the preset growth rate after the power adapter is connected to the system, so as to prompt the power adapter to perform step-by-step discharge. The step-by-step discharge process can be divided into multiple steps corresponding to different load sizes. discharge stage, and the load corresponding to the previous discharge stage is smaller than the load of the next discharge stage; it is also used to control the power adapter to exit the step-by-step discharge when receiving the notification of exiting the step-by-step discharge;

[0079] EC is used to monitor in real time whether the exit condition ...

Abstract

The invention relates to the field of electronic technology, and discloses a method, a device and electronic equipment for acquiring wattage information of a power adapter. The acquisition method includes: after the power adapter is connected, prompting the power adapter to discharge step by step; during the step-by-step discharge process, it is monitored in real time whether the exit condition of step-by-step discharge is currently satisfied, and if it is satisfied, the step-by-step discharge is exited; the exit condition includes: The transient voltage value of the adapter is lower than the voltage threshold, the battery discharge current value exceeds the battery current limit point, or the CPU temperature exceeds the preset temperature threshold; according to the pre-obtained comparison table between the discharge stage and the adapter wattage, the step-by-step discharge exit time is obtained. The wattage information corresponding to the previous discharge stage of the current discharge stage is to obtain the actual wattage information of the power adapter. The invention adopts the method of prompting the power adapter to discharge step by step, and realizes the acquisition of the actual wattage information of the power adapter by means of the conventional logic module of the charging chip, which reduces the implementation cost and has strong practicability.

Description

technical field [0001] The present invention relates to the field of electronic technology, in particular to a method, device and electronic equipment for acquiring wattage information of a power adapter. Background technique [0002] Power adapters are commonly used now, and the notebook computer system cannot directly obtain its wattage information. The preset power adapter current limit and CPU-related setting parameters in the registers of the charging chip on the system motherboard are based on the lower power adapter wattage shipped. It is hard-coded into the embedded controller (EC for short) and the CPU as a standard, and cannot be properly adjusted with the wattage of the external power adapter, resulting in the following problems: [0003] When the user uses a power adapter with a lower wattage, the laptop has a risk of downtime; when using a power adapter with a higher wattage, the surplus wattage cannot be fully used; the user still cannot achieve the performance...
