Introduction to frequently asked questions about EV charging

China [CN]

For many consumers, the biggest fear of driving an electric car is that it quickly runs out of power when walking on the road, or that charging is very slow after running out of power. In actual situations, especially on highways, it is often difficult for electric vehicles to find public charging piles. Even if they are charged, most of them are slow and the effect is not ideal. Especially for buses, taxis, logistics vehicles and shared cars, which have an urgent need for high-power fast charging, if the charging efficiency is not high enough, its operating efficiency and operating income will be directly reduced.

But to achieve high-power charging, we mainly need to solve three technical problems. The first is the acceptability issue of car batteries, that is, whether the battery and car voltage, heat dissipation, etc. can support high-power charging. Another is to do a good job of current sharing and control between charging modules. The more stable the charging module, the higher the integration of the charging pile system. Finally, the charging cable needs to be developed with a 1000V cooling cable. OMG is a company that focuses on the research and development of charging cables. It supports major charging pile companies and car companies at home and abroad, and continuously develops various forms of liquid-cooled charging cables.

In 2017, OMG cable manufacturer, as the first domestic company focusing on conduction products for new energy vehicles, is committed to developing high-power DC charging cables. It uses liquid cooling technology to add a liquid cooling circulation system inside the cable, and achieves cooling through the sealed circulation connection inside the charging gun, so that the cable maintains a low and constant temperature during the charging process. The main purpose is to overcome the thermal damage caused by heat to charging guns, charging cables, and charging piles, thereby increasing the DC charging current and providing customers with safer and faster electric vehicle charging cable solutions.
