The Importance of EV Charge Cable Type 2

If you are already a new energy vehicle (NEV) owner, you may be familiar with issues such as the corrosion of the outer layer of the EV charge cable, potential water ingress inside, or occasional leakage. If you're purchasing an electric vehicle (EV) for the first time, be aware that these problems might arise for you as well. Many people focus more on the charging station and the charging gun, but in reality, the cable is also a crucial component that determines your charging experience and safety.

Why You Should Understand EV Charge Cable Type 2?

An EV charge cable Type 2 connects a home charging station to an electric vehicle (EV) or connects the charging station to the power supply, enabling the safe and efficient transfer of power to charge the vehicle. It plays a critical role in the EV charging system, and NEV owners should fully understand it to ensure that the charging station installed in their parking space is safe and reliable.

Typically, an EV charge cable Type 2 consists of multiple fine copper (or aluminum) conductors, each wrapped in an insulating layer. These conductors are twisted together to form a cable core, with insulating material between the conductors to prevent contact. The entire cable is then wrapped in one or more protective sheaths. Depending on the type of charging station and the usage environment, the EV charge cable Type 2 may include single-phase or three-phase power wires, a grounding wire, and a control signal wire.

Standards and Certifications for EV Charge Cable Type 2

The EV charge cable Type 2 should comply with national standards, industry standards, or international standards, such as China's GB/T standards, Europe's IEC standards, or the US's UL standards, ensuring the cable meets requirements for electrical performance, mechanical performance, temperature resistance, fire resistance, environmental friendliness, and more. The product typically carries relevant certification marks like CCC, UL, CE, etc., to prove it has passed safety tests and quality certification from authoritative organizations.

Types of EV Charge Cable Type 2

Based on the application scenarios and charging modes, EV charge cable Type 2 comes in the following types:

• AC EV Charge Cable Type 2: Used to connect a single-phase or three-phase AC charging station to an EV. Typically used for home slow charging, the cable includes live, neutral, and ground wires.

  
  

• DC EV Charge Cable Type 2: Used to connect a DC charging station to an EV, mainly for public fast charging. The cable includes high-voltage DC positive and negative wires, a ground wire, and possibly communication and control lines.

  
  

• Power Supply Input Cable: Connects the charging station to an electric meter or distribution box, providing power input to the charging station. This is typically a three-phase or single-phase low-voltage cable, such as YJV or RVV types.

  
  

The Importance of EV Charge Cable Type 2

The EV charge cable Type 2 is the critical conduit for transferring electrical power from the charging station to the EV's battery. Its conductivity, insulation properties, and structural strength directly affect charging efficiency, safety, and reliability. High-quality EV charge cables Type 2 can effectively isolate conductors of different voltage levels, preventing electrical shocks, short circuits, overheating, and other safety issues. Its insulating materials and sheathing should have good heat resistance, flame retardancy, and aging resistance to ensure excellent insulation performance under both normal and abnormal conditions.

Standards-compliant EV charge cable Type 2 ensures compatibility with the physical dimensions, electrical parameters, and communication protocols of the charging station and the EV interface, ensuring smooth charging and avoiding interruptions or equipment damage caused by mismatches.

A well-designed EV charge cable Type 2 should also consider the characteristics required for outdoor use, such as UV resistance, waterproofing, wear resistance, and oil resistance, ensuring good performance over long-term use, reducing maintenance or replacement costs, and improving the overall economic viability of the charging system.

The appropriate cable length, flexibility, weight, and easy-to-plug-and-unplug connector design enhance user convenience when using the charging station, especially in confined spaces or situations where the EV charge cable Type 2 needs to be frequently moved.
