Contact monitoring system in gun head of DC charging pile

Main component

Concept:

Dc charging pile gun head contact monitoring system is a device used to monitor the contact state between DC charging pile gun head and electric vehicle charging interface. The system ensures safety and reliability during charging and avoids charging interruption or equipment damage due to poor contact or misoperation. effect Ensure charging safety: Through real-time monitoring of the contact state be

Function:

Ensure charging safety: Through real-time monitoring of the contact state between the gun head and the charging interface, to avoid safety risks caused by poor contact.

Improve charging efficiency: Ensure the stable transmission of current during charging and reduce charging interruption caused by contact problems.

Protection equipment: to prevent overheating or short circuit caused by poor contact, prolong the service life of the equipment.

Working Principle:

The DC charging pile gun head contact monitoring system mainly realizes its function through the following steps:

Signal detection: The system detects the charging gun head through the gun head signal detection circuit, and generates a preset voltage signal when the charging gun head is detected.

Signal isolation and buffering: The voltage following circuit performs isolation buffering on the detected voltage signal to ensure that the signal is not attenuated during transmission.

Photoelectric isolation: The photoelectric isolation circuit further isolates and filters the voltage signal, and converts the voltage signal into a collection signal for the control system.

Signal acquisition and judgment: the control system receives the acquisition signal, and when the acquisition signal reaches the preset voltage threshold, it determines that the charging gun head is correctly inserted, otherwise it determines that the gun head is not inserted properly.

DC CHARGING PIlE SERIES

DC charging pile is an efficient charging facility for electric vehicles, which uses direct current (DC) to directly charge the vehicle battery, significantly reducing the charging time. Compared with traditional AC charging piles, DC charging piles are able to provide higher power output and can usually charge an EV to 80% of its capacity in 30 minutes, providing users with a convenient charging experience.
