Finding the Best Level 2 EV Charger You Can Buy

What is a Home EV Charger?

A home EV charger is a device that allows you to charge your electric vehicle at home. There are two levels of home EV charging: Level 1 and Level 2. Level 1 chargers usually come with the purchase of an EV, except for Tesla. While they are the most common, most EV owners prefer Level 2 chargers since they provide the perfect balance of speed and cost-effectiveness. In fact, around 60% of those who already have Level 1 chargers are considering upgrading to Level 2 chargers.

Both chargers can be plugged into a standard wall outlet - Level 1 to a 120V outlet and Level 2 to a 240V NEMA (National Electrical Manufacturers Association) 14-50 outlet. Other Level 2 EV chargers require to be hardwired into the home's electrical system for an even higher amperage and quicker charging times. These chargers are designed for residential use, allowing EV owners to conveniently charge their vehicles overnight or during extended periods at home.

When shopping for a Level 2 home charging station, several important factors should be considered to ensure you choose the right one for your needs.

Plug Type

The plug type is a crucial consideration when buying a Level 2 charger. Different electric vehicles and charging stations may use different plug types. The two most common plugs are the J1772 and Tesla NACS (North American Charging Standard). The J1772 plug, or the J-Plug, is used by all EVs sold in North America, except for Tesla. Tesla models use a proprietary plug called the NACS across its Supercharger network.

Until recently, NACS was exclusive to Tesla EVs, but the manufacturer has since opened its chargers to non-Tesla EVs, retrofitting its existing Destination Chargers and Superchargers with the Magic Dock, and allowing CCS-enabled EVs to access its robust charging network. Alternatively, third-party adapters such as the Lectron Vortex Plug give EVs in the NACS alliance early access to Superchargers.

Amperage

The amperage or the charging power of a Level 2 charger determines its charging speed. Higher amperage allows for faster charging. However, it's essential to check your electric panel's capacity and ensure it can support the charger's amperage. Common amperage options for home chargers include 16A, 30A, and 40A. Some Level 2 home EV chargers, such as the Lectron V-Box, even have adjustable amp settings, allowing you to customize your charging experience according to your needs.

Cable length

Consider the length of the charging cord, as it determines the flexibility of your charging setup. A longer cable may provide more convenience, allowing you to park your vehicle in various locations around your home. If the installation location is an issue, you may use Tesla or J1772 extension cord for the extra length.

Connectivity

Advanced connectivity features can enhance the user experience. Some Level 2 chargers come with smart features such as Bluetooth or Wi-Fi connectivity, allowing you to monitor, control, and even schedule charging remotely through a dedicated app. This feature can be especially useful for tracking charging progress and managing energy consumption.

Outdoor use

If you plan to have the EV charger installation outdoors, make sure it is rated for indoor and outdoor use. Outdoor-rated chargers are designed to withstand various weather conditions, ensuring durability and longevity. For those living in regions with cold winters, it's essential to also consider the impact of cold weather on your electric car and EV battery to ensure a seamless charging experience year-round.

Certifications

Look for chargers that meet safety and performance standards. Certifications from recognized organizations, such as UL (Underwriters Laboratories) or ETL (Intertek), indicate that the charger has undergone testing to ensure compliance with safety standards.

Installing a Level 2 Charger at Home

Once you've chosen the right Level 2 EV charger for your needs, you'll need to consider the installation method. There are two primary installation options: hardwired and non-hardwired.

Hardwired installation

Hardwired installation involves connecting the charger directly to your home's electrical panel. This method provides a clean and permanent solution but may require professional installation by a certified electrician. Aside from the charger's upfront costs, you also have to take into consideration any possible upgrades needed in your home to be able to accommodate the additional load of high-powered equipment. Electrical upgrades, wiring improvements, and permits may cost you anywhere from a few hundred dollars to a couple of thousands, depending on several factors. While a hardwired installation costs more, it offers the advantage of a fixed, secure charging station. However, hardwired chargers lack mobility and flexibility, making them suitable for homeowners who don't plan to move their charging stations.

Non-hardwired installation

Non-hardwired installation involves using a dedicated outlet for the Level 2 charger. This option provides more flexibility and allows for easier relocation of the charger. It's essential to use a dedicated circuit breaker with the appropriate amperage for the charger. While non-hardwired installations may be more straightforward, they still require professional installation to ensure safety and compliance.

Can You Use an Extension Cord with a Level 2 EV Charger?

Using an extension cord with a Level 2 EV charger is a topic that requires careful consideration. While it might seem like a convenient solution to address charging location challenges, it's crucial to weigh the potential risks and take specific precautions to ensure both safety and charging efficiency.

Key Factors to Consider:

Length

When selecting an extension cord, consider the distance from the power source to your electric vehicle. Choose a cord that provides the necessary extra length without excess slack. Measure the distance accurately to determine the appropriate length, preventing tripping hazards and unnecessary cable wear.

Amp Rating

Ensure that the extension cord's amp rating matches or exceeds the amperage capacity of your Level 2 EV charger. Using an extension cord with an insufficient amp rating can lead to overheating, voltage drop, and safety hazards. It's crucial to understand the amperage requirements of your EV charger and choose an extension cord accordingly.

Wire Gauge

Opt for an extension cord with an appropriate wire gauge for the charger's amperage and voltage requirements. Thicker wires (lower gauge numbers) are better suited for higher amperage, as they reduce the risk of voltage drop and overheating. Always check the manufacturer's specifications for both the charger and the extension cord to ensure compatibility.

Outdoor Use

If you plan to use the extension cord outdoors, ensure it is specifically rated for outdoor use. Outdoor-rated extension cords are designed to withstand exposure to weather conditions, preventing damage and ensuring longevity. Using an indoor-rated cord outdoors could pose safety risks and lead to premature wear.

Quality and Safety Certifications

Choose extension cords from reputable manufacturers that carry safety certifications, such as UL (Underwriters Laboratories) or ETL (Intertek). These certifications indicate that the extension cord has undergone testing to meet safety standards. Prioritize quality and safety to reduce the risk of electrical issues and ensure reliable charging.

Plug and Outlet Compatibility

Check that the extension cord's plug matches the plug type of your Level 2 EV charger and can connect to the power source. It's advisable to consider buying an extension cord from the same manufacturer as your EV charger. Some manufacturers offer extension cords specifically designed for compatibility with their chargers, ensuring seamless integration and optimal performance.

Consultation with a Qualified Electrician

If in doubt or if your charging setup is more complex, consider consulting with a qualified electrician. They can assess your specific situation, provide guidance on the right extension cord length, and ensure that your charging setup complies with local electrical codes and safety standards.

While using an extension cord may address the challenge of limited charging reach, it's essential to prioritize safety and adhere to specific guidelines. Choosing the right extension cord, considering factors like length, amp rating, wire gauge, outdoor use, and compatibility, can help ensure a safe and efficient charging experience for your electric vehicle. Always follow the manufacturer's recommendations and consult with professionals if needed.
