What are DC positive and negative contacts made of?

The components that make up the second point, "DC Positive and Negative Pole Contacts (DC+ and DC- Contacts)," include the following parts:

Main component

This is the main positive contact used for transmitting direct current energy, responsible for transferring electrical energy from the positive pole of the charging pile to the positive pole of the electric vehicle's battery.

This is the main negative contact used for transmitting direct current energy, responsible for transferring electrical energy from the negative pole of the charging pile to the negative pole of the electric vehicle's battery.

To ensure good contact between the contact and the electric vehicle's charging interface, a contact spring is usually equipped to maintain a stable electrical connection.

Contacts are typically made of materials with good electrical conductivity, such as copper or copper alloys, to ensure efficient energy transfer and reduce resistive losses.

Contacts may be equipped with protective covers to prevent the intrusion of dust, moisture, or other contaminants, protecting the contact points from environmental influences.

Used to monitor whether the contacts are correctly connected to the electric vehicle's charging interface, ensuring the safety and effectiveness of the charging process.

These components work together to ensure that direct current energy can be safely and efficiently transferred from the charging pile to the battery of the electric vehicle.

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.
