EV High-voltage cable

EV High-Voltage Cable introduction:

On electric vehicles, the high-voltage electrical system is mainly responsible for starting, driving, charging and discharging, and air conditioning power. It mainly includes battery system, powertrain, high-voltage electronic control system, charging system, high-voltage equipment, and its wiring harness system. Electric vehicle high-voltage lines are used to connect the charging port and the battery, the interior of the battery, the battery and the engine and other components, as well as battery energy storage equipment and other fields, as the carrier of power transmission. Due to the harsh application environment in the vehicle, electric vehicle high-voltage cables have very high performance requirements. Application characteristics of cables for electric vehicles: small wiring space, high current and high voltage, high and low temperature environment, poor heat dissipation, bad driving environment with salt spray and electromagnetic field, oil pollution and chemicals, low smoke halogen-free flame retardant,

EV High-Voltage Cable selection reference

The specifications of high-voltage cables for electric vehicles are generally selected according to rated current or application scenarios. The following table is the corresponding specifications recommended according to different occasions. After the specification is determined, the corresponding reference standard is determined. For example, OMG EV CABLE has ISO 6722 standard, ISO 19642 standard, UL3820 standard, LV216 standard, QC/T 1037-2016 standard. Under the premise of meeting the standards, the color of OMG EV CABLE can be selected from orange or black, the rated temperature can be selected from -40~125 degrees or -40~150 degrees, and the voltage level can be selected from AC600\DC900V or AC1000\DC1500V.
