A Secret Weapon For Facing Energy Risk: EV High Voltage Cable

EV high voltage cable plays a critical role in electric vehicles (EVs) by enabling efficient power transmission between the battery, inverter, and motor.

1. Electric Vehicle Market Growth

The global electric vehicle (EV) market is growing rapidly, and governments have introduced policies to support the development of EVs, such as subsidy policies, burn ban schedules, and carbon neutral targets. This has directly driven the demand for EV high voltage cables.

2. High-voltage cable market demand escalation

The voltage level of the power system of new energy vehicles is increasing (e.g., from 400V to 800V architecture development), which puts forward higher requirements for high-voltage wires in terms of pressure resistance, heat dissipation, flexibility, and shielding performance. High-voltage wire technology iteration will become a trend.

3. Lightweight, high-performance material applications

In order to improve the range, car companies are promoting lightweight design, high-voltage line materials are also being developed in the direction of aluminum alloy conductors, thin-walled insulation, high-temperature resistant materials, for example:

Adoption of high-performance silicone rubber, XLPE, TPU as insulating materials;

Reducing weight by replacing copper with aluminum to improve the energy efficiency ratio of electric vehicles.

4. Charging infrastructure upgrade

With the development of fast charging technology (e.g. super charging station, 800V high voltage charging), high voltage wires are not only used in vehicles, but also widely used in charging piles, high voltage connectors, energy storage systems, etc., which further extends the market demand.

Application：

In electric vehicles, the high-voltage electrical system is mainly responsible for starting, driving, charging and discharging, and air conditioning power. It mainly includes the battery system, powertrain, high-voltage electric control system, charging system, high-voltage equipment, and its wiring harness system. EV high-voltage wires are used to connect the charging port to the battery, inside the battery, the battery to the engine and other components, as well as battery energy storage equipment and other areas, as a carrier for power transmission. Due to the harsh environment of in-vehicle applications, electric vehicle high voltage cables have very high performance requirements. Characteristics of electric vehicle cables: small wiring space, high current and high voltage, high and low temperature environment, bad heat dissipation, poor driving environment, salt spray and electromagnetic fields, oil and chemicals, low smoke, halogen-free flame retardant and other environmental and safety requirements.
