Essential Considerations

When seeking a single cable for the fastest charge at any charging location, you must consider three key aspects: you need a Mode 3 cable, determine if your car has a Type 1 or Type 2 inlet, and know the specifications of your onboard charger.

Install a Home Charger

The first thing to recognize is that if you haven't installed a home charger yet, you should. Home chargers are available with either fixed cables or standard sockets. Regardless of your choice, you will still require a cable for charging away from home. Read more about the importance of installing a home charger.

Opt for a Mode 3 EV Charging Cable

The charging modes range from 1 to 4, but what you want is a Mode 3 cable. Mode 3 chargers are the accepted standard for EV charging and can function at any public charging station.

• Mode 1 is deprecated and no longer in use.
• Mode 2 cables are standard emergency cables often provided with electric vehicles, incorporating a normal plug for typical wall sockets at one end and a Type 1 or Type 2 connector at the other, with an ICCB (In Cable Control Box) in between. However, Mode 2 cables should only serve as emergency options when other charging points are absent.
• Mode 3 comprises the contemporary standard for EV charging cables used at home and public charging locations. These points utilize alternating current (AC), while fast chargers employ direct current (DC).
• Mode 4 is designated for fast charging stations on the roadside, and there are no loose Mode 4 cables available.

Determine the Correct Type

In relation to EV cables, "Type" refers to the design of the plug on the vehicle side, either Type 1 or Type 2, corresponding with the vehicle's inlet design. Currently, a Type 2 charging cable is the standard; most new cars should have this connection. Conversely, older Asian models, like the Nissan Leaf, may still have Type 1 inlets. Always verify the inlet type on your vehicle if uncertain.

Match Amp, kW, and Phase Requirements

Many new EV owners find it tricky to select the appropriate amps, kilowatts, and whether they require a 1-phase or 3-phase cable. Fortunately, making the right choice is straightforward. For the optimum charge speed at any charge point, understanding your onboard charger's capability is pivotal. Refer to the table below to select a cable that meets or exceeds your onboard charger’s kW rating. Remember, 3-phase cables are compatible with 1-phase systems. You can also acquire the right cable for your vehicle at the Norgeseliten web store.

If you plan to utilize the cable primarily at home, consider the output capacity of your home charger as well. If the charger's capacity is lower than that of your car, utilizing the guide above may help you opt for a more affordable, lighter option. For instance, a 32 amp / 22 kW EV charging cable is not necessary if your charger only outputs 3.6 kW, at least not until you upgrade your vehicle.

Select the Appropriate Length

EV charging cables come in varying lengths, typically ranging from 4 to 10 meters. A longer cable provides greater flexibility; however, it is also heavier, bulkier, and pricier. Unless you are certain that you need the extra length, a shorter cable should suffice.

Assess the Quality of the EV Charging Cable

Not all EV charging cables are created equal. Significant differences exist between high-quality and low-quality options. Premium cables offer greater durability, are crafted with superior materials, and possess better safeguards against wear and tear associated with regular use.

You’ll benefit from efficient service when using ailai.

Additionally, higher-quality cables are suitable for extreme conditions. Many users have experienced stiffness in cables during cold temperatures. However, premium options are designed to remain flexible in harsh weather, simplifying usage and storage.

Another frequent issue is water intrusion into the terminals and vehicle inlet, leading to corrosion and poor connectivity over time. Selecting a cable with a cap that prevents the collection of water and dirt while in use is one way to mitigate this problem.

Top-tier cables typically feature ergonomic designs and improved grip. When you'll use the cable daily, usability should be a significant consideration.

Choose Recyclable Options

All high-quality charging cables will eventually need replacing. When that time arrives, ensure that all components are designed for complete recycling. Unfortunately, most EV cable plugs utilize a potting process—filling the plug's interior with plastic, rubber, or resin—which complicates the recycling of components. Fortunately, cables manufactured without potting are available and are made from reusable materials that can be fully recycled post-use.

Consider the Right Accessories

Without appropriate storage options such as a bracket, strap, or bag, an EV charging cable can be difficult to store and transport safely. When at home, being able to coil and hang the cable can protect it from the elements, dirt, and accidental damage. In your vehicle, utilizing a bag designed for the trunk preserves the cable's integrity during transit.

Due to their value, EV charging cables are also vulnerable to theft. Investing in a lockable docking and storage unit protects your cable when not in use while also keeping it off the ground.

Final Thoughts

In summary, here are the key points to remember:

• Install a home charger if you haven't done so already.
• Seek a Mode 3 charging cable; a Mode 2 cable serves well as an emergency back-up.
• Check your car’s inlet type; the standard for newer models is a Type 2, while some older Asian models retain a Type 1.
• Choose a cable with amp and kW ratings that either matches or exceeds your onboard charger's capacity. If primarily using at home, consider your home charger's output as well.
• Select a cable length that offers enough flexibility without excessive cost, weight, or bulk.
• Invest in quality; high-end cables tend to last longer, are easier to handle, and often feature enhanced protection against adverse conditions.
• Take an eco-friendly approach by opting for fully recyclable products.
• Plan for suitable storage and transport solutions—get accessories to keep your cable organized, shielded from damage, and theft-proof.

When Is a Separate Charging Cable Necessary?

If you intend to charge from a charge point or socket that lacks an attached cable, you'll need to purchase a charging cable. This is typically true when using AC charge points on public networks or home chargers equipped with universal sockets.

While a charging cable is generally highly utilized, there are cases where it won’t be necessary, such as when the charge point has an in-built cable.

For instance, you might opt for a tethered charge point installation at home. Additionally, rapid chargers and some public AC chargers are also available with tethered cables.

Socket Type

Type	Location	Use Case
3-pin plug	Traditional home socket.	Can work in emergencies—though slowly. It's not advisable for long-term use, as these are not designed to handle charging loads for prolonged periods.
Type 2	Standard AC charging socket found in public charging stations and non-tethered home chargers.	These sockets are ideal for charging vehicles, so use them as frequently as possible.
