How to Choose electric vehicle EV connectors?

The development of electric vehicles is gradually showing characteristics such as high power, long endurance, and high mileage. High power can improve the acceleration performance and climbing ability of vehicles, long endurance can meet the daily travel needs of users, and high mileage can improve the service life and economy of vehicles. In this context, the importance of performance indicators such as current carrying capacity, thermal cycling, and vibration life of connectors is particularly important.

1,Connector current carrying capacity

The current carrying capacity of a connector refers to the maximum current value that the connector can withstand. With the trend of high-power development of electric vehicles, the current carrying capacity of connectors also needs to be continuously improved. At present, the current carrying capacity of connectors for  electric vehicles on the market is generally between 20A-300A, while the current carrying capacity of connectors for some high-end models has reached 50A-600A. 

2,Connector thermal cycle

The thermal cycle of a connector refers to the temperature change caused by the heat generated by the current passing through the connector during operation. The thermal cycle of connectors has a significant impact on their lifespan and reliability. According to the trend of long-term development of electric vehicles, the thermal cycle of connectors also needs to be continuously improved. 

3,Vibration life of connectors

The vibration life of a connector refers to the changes in its lifespan caused by vehicle vibration during operation. The vibration life of connectors has a significant impact on their lifespan and reliability. With the high mileage development trend of electric vehicles, the vibration life of connectors also needs to be continuously improved. 

In summary, the current carrying capacity, thermal cycle, and vibration life of connectors are important indicators for measuring the quality of connectors for electric vehicles. With the development trend of high-power, long endurance, and high mileage of two wheeled electric vehicles, the performance indicators of connectors also need to be continuously improved. In the future, FUSE will continue to develop new connector technologies to meet the market's demand for continuously improving the performance of connectors for  electric vehicles.
