Application types and characteristics of new energy vehicle connectors

Posted Date: 2024-01-29

The application types of new energy vehicle connectors mainly include electronic connectors, microwave radio frequency connectors and optical connectors.

In new energy vehicles, the main function of connectors is to ensure the normal operation of the high-voltage interconnection system of the entire vehicle. They usually consist of three parts: auxiliary structures such as housings and seals, insulating parts, and conductive contact pairs. These connectors can be divided into different categories based on the transmission medium.

For example, electronic connectors are mainly used for electrical connections, while microwave RF connectors are used for signal transmission, and optical connectors are used for optical fiber communications.

The characteristics of new energy vehicle connectors include high safety performance, high temperature and high pressure resistance, flame retardancy, and electromagnetic interference (EMI) control.

The number of electric drive units and electrical equipment in new energy vehicles has increased significantly compared with traditional fuel vehicles, so the requirements for connectors are also more stringent. These connectors need to be able to withstand currents up to 250A and voltages up to 600V, and must have high standards of protection against electric shock.

In such a high-power environment, electromagnetic interference has become a problem that cannot be ignored.

In addition, since the electric drive system of new energy vehicles works under high voltage and high current conditions, the connector material must be able to withstand high temperatures, high voltages, and have good flame retardant properties, which results in high-voltage connectors for new energy vehicles. The material cost is usually higher than traditional connectors.

In summary, it can be seen that new energy vehicle connectors play a vital role in ensuring the safe and stable operation of vehicle electrical systems, and their design and manufacturing need to meet higher standards and requirements.
