How To Choose Between Tethered And Untethered EV Chargers?

A flexible EV charger can solve many problems, but the choice between tethered or untethered options depends on your specific needs and circumstances. Both options come with their own set of benefits and drawbacks, so let’s take a closer look at each to help you decide.

Tethered EV Chargers

Pros of Tethered Chargers:

• Quick Setup: It takes less time to set up charging for your EV.
• High-Quality Cable: The in-built cable is often of higher quality than aftermarket options.
• No Cable Hassle: You don’t have to worry about forgetting or misplacing the cable.

Cons of Tethered Chargers:

• Bulkiness: The cable could affect the visual appeal of the charger, making it look bulky.
• Cable Management: It can be challenging to keep the cable organised and neat.

A tethered EV charger means the cable is permanently connected to the charging unit. Many homeowners find this configuration convenient because the cable is always on hand. You simply roll out the cable and plug it into your car.

However, there are some downsides to tethered EV chargers, primarily related to the cable’s length. The manufacturer's standard is typically a 5-meter cable, which could limit how you park your car at home. Off-street parking becomes nearly impossible with such a short cable length. However, if you're using tethered public charging, you won’t run into any cable length issues.

Untethered EV Chargers

Pros of Untethered Chargers:

• Sleeker Installation: Tidier installation that takes up less space.
• Cost-Effective: Often much cheaper to install than tethered options.
• Upgrade Flexibility: Easily upgrade to a better cable if needed.

Cons of Untethered Chargers:

• Limited Options: You don’t have many choices when it comes to these types of chargers.
• Risk of Loss: You can risk losing or forgetting your cable.
• Additional Step: Adds an extra step to the EV charging process.

In an untethered charging point, there’s no cable provided with the station. Instead, you must get your own cable and manually attach it to your car’s charging port. Often, you can purchase this cable when you buy your car, and it’s always a good idea to have an extra on hand.

While the extra step might seem inconvenient, untethered chargers offer more flexibility. You can charge any electric car because the socket is universal. Additionally, you’re not limited by the cable length; simply measure your ideal parking distance and buy an appropriate cable.

For homeowners, untethered chargers provide a cleaner look without the mess of visible cabling. Ultimately, the choice between tethered and untethered chargers boils down to user preference, so consider this factor carefully before purchasing your home EV charger.

Other Factors To Consider When Choosing an EV Charger

Apart from deciding between tethered or untethered charging ports, several other factors can influence your choice of EV charger. These considerations can even help you decide between cabled or cable-free charging options.

Decide Where To Install It

The location of your EV charging station is crucial to its functionality. In a domestic setting, you will likely install the charger in your garage or driveway to ensure enough space and easy access. The charger's cable length will also play a role in determining its optimal placement.

Ensure that the EV charger is located close to the electrical panel to prevent any power interruptions in the future. If you’re unsure about the best location for your EV charger, consulting a qualified electrician can provide you with valuable insights and recommendations.

Consider The Charging Speed And Cost

Charging speed significantly impacts both the cost and the practicality of your EV charger. Generally, the higher the kW output of the charging port, the faster your EV will be charged. Fast chargers might be more expensive to install, but they offer the convenience of quicker charging times.

For households, a fast charger is often the ideal option because it provides ample energy to your vehicle without being overly expensive to install. Depending on the capacity and model of your EV, you can expect chargers to range between 7 kW to 22 kW. This allows you to leave your car plugged in overnight and enjoy a fully charged vehicle the next day.

Choose Between A Single-Phase or Three-Phase Charger

Standard residential power outlets are usually single-phase AC devices, while commercial outlets can supply electric cars with three-phase AC. The primary difference is that single-phase chargers provide only a third of the power that three-phase models do, meaning it will take three times longer to charge your EV.

If you plug your EV into a standard single-phase AC outlet, it could take anywhere from 8 to 12 hours to charge from zero to full capacity. However, if you opt for a three-phase charger, you can significantly reduce the charging time, making your EV more versatile and convenient to use.

If you currently own a single-phase charger, upgrading the cable to a three-phase charging system is a straightforward process that can enhance your EV's charging capabilities.

Other High-Quality Features

With rapid innovation in the EV industry, consumers can expect even more advanced chargers in the future. Some excellent features to look out for include:

• Monitoring: Easily monitor your EV’s charging status through a smartphone or tablet.
• Locking Mechanism: Protect your EV charger from unauthorised use with traditional lock and key systems or modern app-based locks that use entry codes and facial recognition.
• Earthing: Most EV chargers require an earthing rod for added safety, but some modern chargers have an in-built earthing component to prevent electric shock and overloading.
• Remote Control: Smart EV chargers allow you to control charging remotely, set schedules, and manage energy usage efficiently.

These features not only enhance the functionality of your EV charger but also provide added security and convenience.

What Are The Different EV Charging Levels?

Not all electric chargers are built the same. Some EV chargers are much faster at topping up your car, while others have a higher energy capacity. In general, charging is categorised into three common levels: Level 1, Level 2, and Level 3. The higher the charger level, the higher the energy output and the faster your car will charge.

Despite these levels, there are still some variations based on the type of battery and the vehicle’s charging capacity. Let’s break down the different charging levels to see how they work.

Level 1 Charging

Level 1 charging refers to plugging your electric car into a standard AC power outlet using a regular household plug. Since a general household socket typically delivers around 2.3 kW of energy, using a Level 1 charger is one of the slowest ways to recharge an EV. In some cases, this energy will only add about 6 to 8 kilometers of range per hour of charging.

Additionally, Level 1 chargers lack communication between the power panel and the car, which can pose safety risks. Due to these reasons, Level 1 charging is best reserved for emergencies or situations where other charging options are unavailable.

Level 2 Charging

Level 2 charging stations are a significant step up from Level 1. These chargers are typically mounted to a wall, a pole, or positioned in the ground, delivering energy between 3.4 kW to 22 kW. You can find Level 2 chargers in residential properties, public parking areas, and commercial locations.

With a maximum charging output of 22 kW, an hour of Level 2 charging can provide a substantial driving range, making it ideal for households. The higher charging capacity, combined with smart connectivity options and multiple safety features, makes Level 2 charging a popular choice among EV owners.

Level 3 Charging

Often referred to as DC fast charging, Level 3 chargers use direct current (DC) energy to power a car’s battery directly, bypassing the need for an onboard converter. This allows Level 3 charging stations to provide high-powered charging at a significantly faster rate, making them ideal for public locations where quick turnaround times are essential.

However, the charging time can still vary depending on the EV model and the power outlet. Generally, you can expect a fully charged EV in mere minutes with a Level 3 charger. Due to their high power output and costly installation, Level 3 chargers are not typically suitable for residential installation but are widely available in public spaces.

Understanding AC vs DC Charging

When you charge an electric vehicle, the alternating current (AC) from the power grid must be converted into direct current (DC) to power your car. Understanding the difference between AC and DC charging is essential for choosing the right charger for your needs.

• DC Charging: DC chargers automatically convert AC to DC, allowing for faster charging speeds. These chargers typically offer higher power outputs, often up to 100 kW or more, making them ideal for rapid charging needs. However, DC chargers tend to be more expensive than their AC counterparts.
• AC Charging: With AC chargers, the vehicle itself converts the AC power to DC, but at a slower rate. This is why most AC chargers top out at around 22 kW, whereas DC chargers can go much higher. While AC chargers are generally more affordable, they provide slower charging speeds compared to DC models.

Choosing between AC and DC charging largely depends on your specific needs, budget, and the charging infrastructure available to you.

Slow chargers typically range between 2.3 kW to 6 kW, with some reaching up to 3 kW. One critical thing to remember is that slow EV chargers are usually untethered, meaning you need to have your own cable to connect them to the charge point.

Fast EV Charging Points

Fast EV chargers offer a better charging performance compared to slow chargers. They are perfect if you leave your car parked for a few hours, such as during a shopping trip or a few hours at work. Fast chargers range from 7 kW to 22 kW and are commonly found outside homes, in public parking areas, and at commercial locations.

Rapid EV Charging Points

For those who need high-speed charging, rapid EV chargers are the way to go. These chargers typically range between 50 kW to 100 kW, allowing you to fully charge your vehicle in less than 30 minutes. Despite their high speeds, rapid chargers are not suitable for household installation due to their costly setup. Instead, they are commonly found in public spaces like highways, shopping centers, and large parking lots.

Ultra-Rapid EV Charging Points

Ultra-rapid EV chargers take charging speeds to the next level, providing power outputs of 100 kW or more. These chargers can top up your car in just minutes, making them incredibly convenient for long-distance travel or quick stops. However, like rapid chargers, ultra-rapid chargers are typically not feasible for residential installation and are best suited for strategic public locations.
