Problems solved by technology

However, because the limit switch is easily touched by other foreign objects, misjudgment may occur, and multiple limit switches will cause high cost and low reliability.
In addition, through microwave, laser and other methods, there are problems such as being easily disturbed by foreign objects, and the equipment is complex and easy to damage.

Abstract

The invention discloses a magnetic conductive plate for positioning a detachable transformer. The magnetic conductive plate comprises a supporting plate and a plurality of magnetic conductive bodies;a plurality of through holes are formed in the supporting plate, the coils are wound around the magnetic conductive bodies and connected with an electromotive force detecting circuit, and the magneticconductive bodies with the wound coils are embedded and fixed into the through holes. During charging, alternating flux is generated on the magnetic conductive bodies abutting against the detachabletransformer in a attached mode, alternating electromotive force is generated in the corresponding coils, which magnetic conductive body coil generates the alternating electromotive force is detected through the electromotive force detecting circuit, and thus the position of the detachable transformer abutting against the detachable transformer in the attached mode can be judged; due to the fact that a magnetic field generated by the detachable transformer is sensed, the identification discrimination degree is high, and the magnetic conductive plate is not prone to being influenced by foreign matter and other disturbance; and the weak link that mechanical parts and optical parts are prone to being consumed and damaged is avoided, thus reliability is high, and the cost is low.

Description

technical field [0001] The invention relates to a magnetically conductive plate for positioning a separable transformer, belonging to the technical field of electric vehicle charging. Background technique [0002] The high-power and high-efficiency charging requirements of electric vehicle charging can be realized through the separable transformer mode, using the structure of the secondary side of the electric vehicle side separable transformer, the ground oriented magnetic guide plate, and the ground separable transformer primary side. The secondary side of the separable transformer of the electric vehicle automatically descends to the directional magnetic guide plate after parking, and the primary side of the separable transformer is aligned with the secondary side of the separable transformer to generate magnetic flux, which is coupled with the secondary side of the separable transformer through the directional magnetic guide plate , transfer electric energy. Compared wi...
