In the prior art, most charging connection methods realize the conversion between charging modes, but lack the analysis of the most basic and most common problem of the connection status between the charging plug and the socket. Analyzing the connection status between the socket and the plug can not only analyze the charging quality of the device, but also reflect the various reasons that affect the charging of the device during the charging process, so that we can better understand and grasp the charging status of the device.

To this end, the present invention provides a high-current signal light charging connection method.

The insertion resistance deviation factor and the insertion resistance fluctuation deviation factor are processed by data, and the formula is: Obtaining a connection state parameter DW between the plug and the socket, wherein α and β are both preset proportional coefficients;

S2, comparing the connection state parameter DW with the connection state parameter threshold, determining the actual connection state between the plug and the socket according to the comparison result, and generating a signal, the signal including a normal signal and an abnormal signal;

Among them, if a normal signal is generated, the signal light continues to be charged. If an abnormal signal is generated, the charging power deviation parameter JK is obtained. According to the charging power deviation parameter JK and the connection state parameter DW, the charging quality characterization value Vg is output. According to the comparison result between the charging quality characterization value Vg and the charging quality characterization value threshold, the charging quality of the signal light is analyzed, and according to the analysis result, it is determined whether the signal light needs to continue to be charged after adjustment.

As a further technical solution of the present invention, the insertion resistance deviation factor GJ is obtained in the following manner:

The actual resistance between the plug and the socket is processed with the reference resistance between the plug and the socket, and the absolute value of the difference is taken to obtain the deviation resistance. The deviation resistance between the plug and the socket is processed with the reference resistance to obtain the insertion resistance deviation factor.

As a further technical solution of the present invention, the insertion resistance fluctuation deviation factor GF is obtained in the following manner:

The real-time resistance corresponding to the different detection time points are marked and connected in the X-Y coordinate system to obtain the real-time resistance change curve after the plug and the socket are fully plugged in, and it is marked as a comparison curve. The real-time resistance change curve of the plug and the socket in the actual plugged state is obtained in the same way as the comparison curve acquisition method, and is marked as the actual curve;

The area enclosed by the actual curve and the X-axis is calculated to obtain the actual curve fluctuation area. The area enclosed by the comparison curve and the X-axis is calculated to obtain the comparison curve fluctuation area. The actual curve fluctuation area is different from the comparison curve fluctuation area, and the absolute value of the difference is taken to obtain the curve fluctuation area deviation value. The curve fluctuation area deviation value is ratioed with the comparison curve fluctuation area to obtain the insertion resistance fluctuation deviation factor.

As a further technical solution of the present invention, the actual resistance is obtained by:

The detection time is divided into several continuous and equal time sub-units, and based on the comparison curve, the maximum resistance and the minimum resistance corresponding to each time sub-unit in the state where the plug and the socket are fully plugged in are obtained, and the maximum resistance and the minimum resistance are summed and averaged to obtain the average resistance corresponding to each time sub-unit in the state where the plug and the socket are fully plugged in, and the average resistance corresponding to all time sub-units in the state where the plug and the socket are fully plugged in are summed and averaged to obtain the comparison resistance;

The average resistances corresponding to all time sub-units in the actual plugged-in state of the plug and the socket are summed and averaged to obtain the actual resistance.

As a further technical solution of the present invention, the connection state parameter DW is compared with a connection state parameter threshold:

If the connection state parameter DW ≥ the connection state parameter threshold, it means that the actual connection state between the plug and the socket is good, and a normal signal is generated;

If the connection status parameter is less than the connection status parameter threshold, it indicates that the actual connection status between the plug and the socket is poor, and an abnormal signal is generated.

As a further technical solution of the present invention, the charging power deviation parameter is obtained in the following manner:

Detect the amount of charge that the signal light of the plug and the socket has within the detection time when they are actually plugged in, and mark it as the actual amount of charge;

The charging deviation power is processed by ratio processing with the charging power of the signal light when the plug and the socket are fully plugged in during the detection time, so as to obtain the charging power deviation parameter JK.

As a further technical solution of the present invention, the charging quality characterization value Vg is compared with the charging quality characterization value threshold:

If the charging quality characterization value Vg ≥ the charging quality characterization value threshold, it means that the charging quality of the signal light in the actual plug-in state is good, and no plug-in adjustment is required;

If the charging quality characterization value Vg is less than the charging quality characterization value threshold, it means that the charging quality of the signal light in the actual plugged-in state is poor and plugging adjustment is required.

If the charging rate deviation parameter is less than the charging rate deviation parameter threshold, it means that the reason for the poor charging quality of the signal light is not only the poor connection between the signal light plug and the socket, but also other reasons, and the signal light needs to be checked.

As a further technical solution of the present invention, the charging rate deviation parameter DFg is obtained in the following manner:

After a period of charging time, the battery power is detected, the detected battery power is processed with the battery power of the signal light before the insertion adjustment, and the absolute value of the difference is taken to obtain the charging power of the signal light after the adjustment, and the charging power of the signal light after the adjustment is processed with the corresponding charging time to obtain the charging rate of the signal light after the adjustment;
