Buried charging device and charging method

The invention belongs to the field of new energy vehicles and in particular relates to a buried charging device and a charging method in the field. The buried charging device comprises a control host, a buried charging pile and a charging plug, wherein the buried charging pile is connected with the control host, and the charging plug is arranged on the buried charging pile; the buried charging device is characterized in that a plurality of sensors are arranged on the buried charging pile; the sensors are connected with the control host; a sign connected with the control host is arranged; and the charging plug on the buried charging pile is connected with a lifting device. The buried charging device can achieve that one host controls the plurality of buried charging piles; and as charging port automatic connection is adopted and the buried charging pile does not occupy any ground road, defects of the various traditional charging piles are effectively avoided, the bottleneck restricting the development of the e
