New energy vehicle high-speed connector knowledge popularization

High-speed connectors for new energy vehicles are one of the important components in the field of new energy vehicles. It is a key component in electric vehicle charging and is responsible for transferring electrical energy from the charging device to the battery pack of the electric vehicle. This article will introduce the basic knowledge, classification, characteristics, application and future development trend of high-speed connectors for new energy vehicles.

Ⅰ, Basic knowledge

The new energy vehicle high-speed connector is an electronic connector, also known as a charging plug. It is an electrical connector used to connect the cable between the power supply and the electric vehicle. High-speed connectors for new energy vehicles are usually composed of parts such as a shell, plug, socket, contact and seal. The plug is usually installed on the charging device, and the socket is installed on the electric vehicle. The contacts of the connectors are usually made of copper and have good electrical conductivity and corrosion resistance.

New energy vehicle high-speed connectors can be divided into two types, AC and DC, according to their transmission speed and power. The AC connector is suitable for AC charging and the DC connector is suitable for DC charging. The transmission speed of AC connector is generally 3.7kW-22kW, and the transmission speed of DC connector is generally 50kW-350kW.

Ⅱ. Classification

New energy vehicle high-speed connectors can be divided into wired and wireless types according to their different transmission media.

1, wired connector

A wired connector is a connector that connects a charging device to an electric vehicle through a cable. The advantage of wired connectors is that the transmission speed is fast, stable and reliable, the disadvantage is that the space outside the vehicle needs to be occupied, and long-term use may lead to cable wear or damage.

2, wireless connector

Wireless connectors refer to connectors that transmit electrical energy through electromagnetic waves, also known as wireless chargers. The advantage of the wireless connector is that it is easy to use, does not need to occupy the external space of the vehicle, and has a long service life. The disadvantage is that the transmission speed is not as fast as the wired connector, and special charging equipment is required.

Ⅲ. Characteristics

1. High efficiency

The transmission speed of the new energy vehicle high-speed connector is fast, and it can charge quickly, improve the charging efficiency, and greatly shorten the charging time.

2. Security

The new energy vehicle high-speed connector has good safety performance and can ensure the safety of the charging process. There are a variety of protection measures inside the connector, such as over-current protection, over-voltage protection, over-temperature protection, etc., which can effectively avoid safety problems in the charging process of electric vehicles.

3. Reliability

High-speed connectors for new energy vehicles have good reliability and can work stably for a long time. The contact of the connector is made of copper, which has good electrical conductivity and corrosion resistance, and can ensure the stable transmission of the connector for a long time.

4. Applicability

New energy vehicle high-speed connectors are suitable for all kinds of electric vehicles, whether pure electric vehicles, plug-in hybrid electric vehicles or fuel cell vehicles, you can use high-speed connectors for charging.

Ⅳ. Application

High-speed connectors for new energy vehicles play an important role in the field of electric vehicle charging. Most charging devices require a high-speed connector for charging. At present, high-speed connectors for new energy vehicles have been widely used in various charging equipment and electric vehicles.

Ⅴ. Future Development Trend

With the rapid development of new energy vehicles, high-speed connectors for new energy vehicles are also growing. In the future, high-speed connectors for new energy vehicles will be more intelligent, portable, safe and efficient. At the same time, wireless connectors will also be more widely used and become one of the important ways of charging new energy vehicles.

In short, high-speed connectors for new energy vehicles are one of the important components in the field of new energy vehicles, with the characteristics of efficiency, safety, reliability and applicability, and have been widely used in various charging equipment and electric vehicles. In the future, high-speed connectors for new energy vehicles will be more intelligent, portable, safe and efficient, and become one of the important ways of charging new energy vehicles.
