Problems solved by technology
[0003] However, in the actual application of wearable devices, the battery power display of wearable devices has always had a large error, and the actual battery power of wearable devices cannot be accurately displayed, which makes the user experience poor. Due to the small size of wearable devices, the batteries equipped with wearable devices are also relatively small in size and have small battery capacity (usually the battery power range of wearable devices is 50mAh-350mAh), so it is difficult to accurately obtain battery power; on the other hand However, due to the limited size of wearable devices, it is not possible to set a special chip for battery power detection in wearable devices, and setting up chips will also bring additional costs. However, the existing method is usually to collect the voltage of the battery to determine the The corresponding voltage interval range, so as to obtain the corresponding power display value, but due to the actual application of the battery (especially lithium battery), there will be high and unstable virtual power when charging, and there will be excessive voltage drop or back pressure during discharge. , will cause a large jitter in the voltage, resulting in inaccurate power display value obtained according to the collected voltage

The invention discloses a battery electric quantity processing method and device. The method comprises the following steps: determining a battery state of a target battery in a current sampling period; obtaining a sampling voltage value of the target battery in the current sampling period; and according to the battery state and pre-obtained mapping information between battery voltages and an electric quantity, obtaining a display electric quantity value of the target battery corresponding to the sampling voltage value. According to the invention, the obtained electric quantity value can be more accurate, besides, fewer processing resources are consumed, and the chip cost does not have to be additionally increased.
Description
technical field [0001] The present invention relates to the technical field of battery processing, and more specifically, to a battery power processing method and equipment. Background technique [0002] With the development of smart device technology, wearable devices are becoming more and more popular as an emerging smart device application. Users can obtain various application experiences such as virtual experience and health management through wearable devices. [0003] However, in the actual application of wearable devices, the battery power display of wearable devices has always had a large error, and the actual battery power of wearable devices cannot be accurately displayed, which makes the user experience poor. Due to the small size of wearable devices, the batteries equipped with wearable devices are also relatively small in size and have small battery capacity (usually the battery power range of wearable devices is 50mAh-350mAh), so it is difficult to accurately o...
