When amount is in the first offset ranges, it is believed that the contraposition of receiving coil and transmitting coil is very accurate, and the offset of the two is to filling
The influence of electrical efficiency is little, without the position of mobile receiving coil, can not alarm at this time, i.e., first offset ranges with not
The alarm level 1 of alarm is corresponding；When offset is in the second offset ranges, it is believed that pair of receiving coil and transmitting coil
Position is more accurate, and influence of the offset of the two to charge efficiency within an acceptable range, can choose movement or not move reception
The position of coil need to only prompt the offset at this time, i.e. second offset ranges and the alarm that need to be only prompted
Rank 2 is corresponding；When offset is in third offset ranges, it is believed that the contraposition inaccuracy of receiving coil and transmitting coil,
Influence of the offset of the two to charge efficiency is very big, it is necessary to which the position of mobile receiving coil makes receiving coil and transmitting coil
Accurate contraposition needs high severity alarm to arouse attention at this time, i.e. third offset ranges and the alarm level 3 of high severity alarm are right
It answers.

Step 2041a, in multiple offset ranges, current offset range locating for current offset is determined.
Step 2041b, according to the second corresponding relationship, the corresponding alarm level of current offset range is determined as current inclined
The alarm level of shifting amount.
Optionally, after determining current offset, it can be based on the second corresponding relationship, determine that the current offset is in the
In the multiple offset ranges recorded in two corresponding relationships in which offset ranges, and then determine the alert level of current offset
Not.
Illustratively, the second corresponding relationship of the offset m and alarm level that prestore please refer to table 1, it is known that second correspondence
The offset ranges recorded in relationship are respectively m<2 millimeters, 2 millimeters≤m≤4 millimeter and m>4 millimeters, wherein m indicates offset
Amount, it is assumed that current offset is 2 millimeters, then can determine that current offset belongs to the offset ranges of 2 millimeters≤m≤4 millimeter,
Correspondingly, can determine that the alarm level of current offset is 2 grades.
Table 1
| Offset ranges | Alarm level |
| M < 2 millimeter | 1 grade |
| 2 millimeters≤m≤4 millimeter | 2 grades |
| M > 4 millimeter | 3 grades |
