Cable requirements for charging new energy vehicles

As the energy supply device of electric vehicle, the charging performance of electric vehicle charging pile is related to the service life and charging time of the battery pack. This is also one of the most concerned aspects for consumers before purchasing electric vehicles.

For the charging model selection of electric vehicles, in principle, we have determined the charging mode to be used and the current output from the charging mode to select the corresponding cable.

The selection of charging mode 4 cable. The charging mode 4 is DC charging, which has obvious advantages such as high charging current and fast charging speed. Therefore, the requirements for safety are higher, the cable diameter is thicker, and the cables including the main power line also need to add ground wires, auxiliary power lines, and control lines. There are more requirements for cables. The selection of cables requires attention to product flexibility and bending radius; High and low temperature resistance, oil resistance, acid and alkali resistance, water resistance, abrasion resistance, crack resistance and UV resistance; Flame retardancy; Conductivity, conductor temperature rise; Whether the materials conform to the latest environmental protection standards of ROHS&REACH, it will be more guaranteed to select products with product qualification.

How large is the cable for 60kw charging pile?

Of course, the single-phase charging pile is generally 7KW (AC charging pile), I=P/U=7000/220=32A, and 4 mm2 copper core cable should be used. Three phase charging pile (DC pile) 15KW current 23A cable 4mm2 30KW current 46A cable 10mm2 60KW current 92A cable 25mm2 90KW current 120A cable 35mm2.
