Charging wire and method for displaying charging state

Abstract

The invention relates to a charging wire. The charging wire comprises a power supply port, a connecting port and a lead wire. The connecting port is provided with a current detection apparatus connected in series with the lead wire, the current detection apparatus comprises two branches, one branch is connected with a resistor R or an inductor L, the other branch is connected with a current detection IC and a comparison and an LED lamp group which are connected with the output end of the current detection IC, the LED lamp group comprises a first lamp, a second lamp and a third lamp which have different colors, the first lamp, the second lamp and the third lamp are at a rapid charging state, a slow charging state and a fully charged state in response to an electronic product, and the current detection IC detects the current value of the resistor R or the inductor L and outputs voltage with different values to the comparator according to the size of the current value to enable the comparator to drive one from the first lamp, the second lamp and the third lamp to emit light according to the size of the voltage. According to the invention, the different charging states of the electronic product are indicated through the LED lamps having the different colors, users can distinguish the current charging state of the electronic product by a simple glance, and thus time is saved for the users.

Description

technical field [0001] The invention relates to the field of electronic product accessories, in particular to a charging line capable of displaying the charging state of the electronic product and a method for displaying the charging state of the electronic product. Background technique [0002] At present, there are many types of charging cables on the market. Generally speaking, the structure is: one end is connected to a power supply device, the other end is connected to electronic products such as mobile phones and tablet computers, and the two ends are connected by wires. During the charging process, the charging status needs to be known through the display on the electronic product. The indicator lights on some electronic products are not only small but also dark. At a long distance, the user cannot judge the charging status, and some electronic products even go to sleep because of power saving. mode, the user needs to wake up to determine its charging status, which u...
