Charging speed is an important factor limiting the development of electric vehicles, and high-power charging is the dominant trend for future growth. Fast charging can significantly shorten the charging time. Shorten the charging time, but the high current inevitably brings the problem of heat generation. The accumulation of large amounts of heat will not only accelerate the aging of the cable insulation or sheath, but also damage the cable, bringing life to the user. The accumulation of a large amount of heat will not only accelerate the aging of the cable insulation or sheath, but also even damage the cable, threatening the user's life and property safety.

Solutions provided by professional cable manufacturers:


Nowadays, professional cable manufacturers have realised this problem and applied some proven heat dissipation solutions in their product design. Take our customer's customised DC fast charging cable as an example.


Option 1: Increase the cross sectional area of the conductor to increase the load capacity, but this will increase the form factor and weight of the cable, causing inconvenience in use.


Option 2: Change auxiliary materials to reduce heat transfer thermal resistance; change the filler, winding tape and other structural materials. Adopt new materials with good thermal conductivity to conduct heat to the sheath, reduce the temperature rise of the core and enhance the load capacity.


Option 3: Adopt cooling heat dissipation technology; add cooling tubes or coolant in the cable to take away the heat through the cyclic operation of the cooling system, which allows greater current charging without increasing the size of the cable.
