Performance requirements for high power liquid-cooled charging cables

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.
