Electric vehicles need fast and safe charging to meet users' needs. Firstly, from a practical point of view, fast charging can greatly shorten the waiting time of vehicle owners and enhance the experience of use. For example, on long-distance trips, if the charging time is too long, it will not only affect people's travel plans, but also may trigger users' range anxiety. Secondly, safe charging is the basic need of every car owner. After all, frequent charging accidents will greatly reduce people's confidence in EVs and negatively affect their market prospects. Currently, the market achieves high-efficiency charging of trams through liquid-cooled charging technology:

1. Heat dissipation principle:

   - Using the heat absorption and conduction characteristics of coolant, the heat generated during charging is exported through circulation.

   - It keeps the working temperature of the battery in a suitable range, improves the charging efficiency, and prevents overheating from decreasing the efficiency and shortening the service life.

2. Liquid cooling system composition:

   - Including power pump, liquid circulation channel and coolant.

   - The power pump drives the coolant circulation, and the liquid circulation channel is located between the cable and the charging gun.

3. Technical Advantages:

   - Supports higher current for fast charging.

   - Reduce the heat of the cable to avoid overheating, increasing the cross-sectional area of the wire is not a necessary condition.

As an excellent new energy charging application technology provider, OMG' has ploughed deeply into the field of electric vehicle charging cables for many years, focusing on the research and development of high-quality charging cables, and paying attention to the industry certification.OMG' liquid-cooled charging cables have been certified by UL, IEC, TUV, and CQC, and make use of the liquid-cooling technology, which makes it possible for the cable to keep a low and constant temperature during the charging process by cooling down. Charging process to maintain a low constant temperature, to overcome the heat damage to the charging gun, charging cable, charging pile heat, so as to improve the DC charging current of a programme. It can fill up the car battery or quickly replenish the battery in a short time to improve the user experience. Liquid-cooled charging cable is an important development direction of electric vehicle charging technology, OMG' is committed to providing reliable and efficient charging solutions for the popularisation and promotion of electric vehicles.
