Problems solved by technology

However, there is an upper limit to "open source" and "throttling". For example, due to the miniaturization / thinness of wearable devices, the increase in battery capacity will be limited by the size of wearable devices, and low power consumption will be limited by technology.

Abstract

The embodiment of the invention discloses a charging device. The device comprises: a voltage adjustment module, wherein the input end of thevoltage adjustment module is connected with the output end of an adapter; a charging module, wherein the input end of the charging module is connected with the output end of the voltage adjusting module, and the output end of the charging module is connected with the input end of the battery; and a feedback loop, wherein the feedback output end of the feedback loop is connected with the feedback input end of the voltage adjusting module, is also connected with the output end of the voltage adjusting module and the input end of the charging module, and is also connected with the input end of the battery and / or the charging module. The corresponding feedback voltage is provided for the voltage adjusting module in real time according to the input voltage of the battery through the feedback loop, the voltage adjusting module adjusts the input voltage provided for the charging module according to the feedback voltage, the obtained input voltage of the charging module is N times of the output voltage of the charging module so as to achieve quick charging of the battery, and through hardware feedback, the response speed is high, and the adapter does not need to be customized and a software communication protocol does not need to be configured.

Description

technical field [0001] The invention relates to the technical field of charging of wearable devices, in particular to a charging device. Background technique [0002] At present, the functions of wearable devices are becoming more and more abundant, but battery life is a major pain point, and the industry mainly uses three methods of "open source", "throttling" and "fast charging" to improve battery energy density, increase capacity, and increase charging. power to increase battery life. However, there is an upper limit to "open source" and "throttling". For example, due to the miniaturization / thinness of wearable devices, the increase in battery capacity will be limited by the size of wearable devices, while low power consumption is limited by technology. Therefore, fast charging has become the first choice to solve the battery life of wearable devices, and how to realize fast charging for batteries of wearable devices has become a major subject of in-depth research by tho...
