High Quality Charging Cables

In this innovation-driven era, the requirements for charging cables go far beyond the simple transmission of electrical energy. Modern charging cables not only need to have excellent physical properties and environmental adaptability, they also need to meet changing technical standards and user expectations. From slow charging at home to public fast charging stations to wireless charging in the future, every innovation in charging cable technology is a sign that we are one step closer to a greener, smarter future. High-quality charging cables should have the following properties:

Safety: High-quality charging cables should ensure safety during the charging process, and should have excellent insulating properties to isolate high voltage and prevent current leakage and risk of electric shock. They should also have safety features such as overload protection, short circuit protection and temperature control.

Durability: charging cables need to withstand frequent plugging and bending, so they should be made of high-temperature-resistant and abrasion-resistant materials to ensure that they are not easy to break or be damaged after prolonged use.

Transmission efficiency: the transmission efficiency of high quality charging cable is directly related to the charging speed, it should have low resistance and low loss characteristics to improve the efficiency of power transmission, reduce energy loss and realise fast charging.

Compatibility: As different electric vehicles may adopt different charging standards and interfaces, high-quality charging cables should have a wide range of compatibility to adapt to the needs of different vehicles and charging piles.

In addition to the key properties mentioned above, high quality charging cables should also consider the following factors:

Environmental adaptability: the cable should be able to withstand harsh weather conditions, with waterproof, UV and cold resistance to ensure charging safety and reliability.

Environmental friendliness: As environmental awareness increases, charging cables using environmentally friendly materials and manufacturing processes are more popular in the market.

When choosing charging cables, it is important to consider not only their performance, but also the specific charging needs and usage environment of the EV, as well as long-term maintenance costs, in order to make a comprehensive decision.The charging cables supplied by OMG' comply with multi-national certifications and are flexible, oil and water resistant, abrasion and tensile resistant, acid and alkali resistant, UV resistant and flame retardant, guaranteeing an efficient and safe charging process.

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.

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.

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.
