Increasingly high reliability requirements for the charging process of dc charging piles

Under the pressure of low cost, charging piles are still facing great challenges in order to be safe, reliable and stable. Because the ev charging station is installed outdoors, the dust, temperature, and humidity are not very well guaranteed, and the environment is relatively harsh. Under special working conditions such as high latitude, high cold, and high altitude, the performance requirements for the charging module are extremely high.

At present, the 30kW charging module is mainly dissipated by forced air cooling, which inevitably brings dust, corrosive gas, moisture and other interference, so the module failure is mainly concentrated in the “hot fryer” phenomenon caused by the environment.

The reliability of the charging pile is more manifested in the reliability of the charging module, in addition to the conventional electrical performance EMC stipulated in the national standard, more need to consider the environmental tolerance, such as moisture, dust, etc., high protection products are now slowly beginning to enter the mainstream market, in addition to the conventional three-proof spraying, glue filling, liquid cooling, independent air duct and other solutions will become more and more mature.

This is the end of the series of articles about the charging pile charging module, after that will launch more about the ev charging pile industry’s professional and related articles news and so on, please pay more attention.
