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.

Electric vehicles rely on electricity to drive the car, and electric vehicle charging cable is the carrier of electric vehicle and power connection, is one of the key components of electric vehicle electric energy conduction system. In order to complete the whole charging process more safely and reliably, the charging cable not only needs to transmit information, but also needs to be automatically controlled when necessary.

The charging and discharging process of electric vehicles is characterized by long duration, high current intensity, and high frequency of cable usage, and the safety of vehicle charging has become a key concern of the industry. Charging pile in outdoor use, charging cable may be sunlight, weathering, oil, humidity, freezing and other adverse conditions, and in use is likely to often have to bend, drag, which will inevitably cause the cable scratching, wear and tear, crushing and other damage. Electric vehicle charging cable should have high heat resistance and aging resistance based on good insulation properties. At the same time, it should have good low-smoke flame retardant properties when burned to ensure that losses and injuries are minimized.

The traditional cable line with low current-carrying capacity, charging speed is slow, the industry's current can quickly cool down charging program is to use liquid-cooled charging technology, so that the cable in the charging process to maintain a low constant temperature, to overcome the heat on the charging gun, charging cables, charging pile of heat damage, so as to improve the DC charging current. The difficulty of liquid-cooled cable design lies in the sealing of the cooling medium, which will directly affect the safety and efficiency of the charging process.OMG's high-power liquid-cooled charging cable meets the European standard certification, suitable for DC 1000V/1500V, and realizes a maximum current-carrying capacity of 1000A, and the cable's outer diameter can be 24mm, which is more conducive to the charging equipment, and the minimum bending radius is 6OD. The cable is designed with liquid-cooling technology to significantly increase the current-carrying capacity and create a good cooling effect.

The cable is a more critical part of the charging system. Electric vehicle charging requires a charging cable to connect the car to the power source. The basic function of a charging cable is to transmit power and control charging. Commonly used in charging stations, parking lots, hotels, communities, garages and other areas, the portable charging cable is suitable for placing in the car.
During the charging and discharging process of electric vehicles, due to the long use time, high frequency of use and high current intensity of cables, the safety of electric vehicle charging has become the focus of the industry. On the basis of ensuring excellent insulation performance, the cable should also have high aging resistance, heat resistance, oil resistance, weather resistance and other properties. Since it is often bent and dragged during use, the flexibility and mechanical properties of the cable are also required.
There is no doubt that the electric vehicle market will continue to grow. OMG charging cable solutions enable you to charge your electric vehicle more safely and efficiently, providing a pleasant charging experience.

1. Transmission capacity of charging cable: The transmission capacity of charging cable directly affects the charging speed of fast charging. Fast charging usually adopts DC charging mode, which requires high charging power. Therefore, charging cables need to have sufficient conductivity to stably transmit high power. OMG' focuses on providing electric vehicle charging cable solutions, and selects high-quality charging cable materials and appropriate cross-section area of wires according to the actual demand, which can reduce the resistance of the cable, improve the charging efficiency and realise fast charging.

2. Durability of charging cables: During fast charging, charging cables are subject to high currents and frequent plugging and unplugging operations, so their durability is critical. Cables with poor durability are prone to damage or overheating, thus affecting charging effect and safety. In order to improve the durability of charging cables, OMG' puts the use of high-quality materials and structural design into production, increasing the tensile strength and abrasion resistance of the cables, as well as paying attention to the correct operation and maintenance in the process of use.

3. Temperature management: During fast charging, the charging cable and connector may generate a certain amount of heat, which requires effective temperature management. Excessive temperature will affect the conductivity and safety of the charging cable, and even lead to potential safety hazards. Therefore, charging cables should have good heat dissipation performance, and OMG' improves the temperature management capability by optimising the heat dissipation structure and increasing heat dissipation materials. Our liquid-cooled charging cables utilise liquid-cooling technology to incorporate a liquid-cooling circulation system inside the cable, and a structural form that allows the cooling system and charging system to co-exist and function together through a sealed circulation connection inside the charging gun. This allows the cable to maintain a low and constant temperature during the charging process, overcoming the thermal damage caused by heat generation to the charging gun, charging cable and charging pile, thus increasing the DC charging current.

4. Safety considerations: charging cable as an important link in the transmission of electricity, safety is a factor that can not be ignored. OMG's design and manufacture of charging cables, follow the relevant safety standards and norms, cables are in line with the European standard, the American standard, the Japanese standard, the Chinese standard and other standards in the industry, to ensure that the cable's insulation and voltage resistance, to prevent electric shocks and fires and other safety issues occurring.
