how to install ev charger in garage



Installing an EV charger in your garage is a great way to conveniently charge your electric vehicle at home. With the increasing popularity of electric cars, having a reliable and efficient charging solution is essential. In this article, we will guide you through the process of installing an EV charger in your garage, helping you understand the necessary steps, considerations, and equipment involved. By the end, you'll be equipped with the knowledge to set up your own charging infrastructure and power up your electric vehicle with ease.

Choosing the Right EV Charger:

The first step in installing an EV charger in your garage is selecting the right charger for your specific needs. There are various types of chargers available, and each has its own advantages and limitations. Let's explore some of the most common options:

Level 1 Chargers:

Level 1 chargers are the most basic and typically come with your electric vehicle. They use a standard 120-volt outlet, which means they can be plugged into any standard outlet found in your garage. While convenient, Level 1 chargers are relatively slow and can take several hours to fully charge your vehicle. If you have a shorter commute or don't mind leaving your car plugged in overnight, a Level 1 charger may suffice.

Level 2 Chargers:

Level 2 chargers provide a faster charging solution by using a 240-volt outlet instead of the standard 120-volt outlet. These chargers require a dedicated circuit and professional installation to ensure safety and compliance with electrical codes. While they are more expensive than Level 1 chargers, Level 2 chargers offer significantly faster charging times, making them ideal for daily use.

Fast DC Chargers:

Fast DC chargers, also known as Level 3 or DC Fast chargers, are the fastest charging option available and are commonly found in public charging stations. These chargers utilize high-voltage direct current (DC) to quickly charge your vehicle. However, they require specialized equipment, professional installation, and are not typically suitable for home garages. DC Fast chargers are advantageous for long-distance traveling or when you need a quick charge on the go.

Choosing the Location:

Once you've selected the appropriate EV charger, it's time to determine the best location for installation in your garage. Consider the following factors when choosing the location:

Proximity to Electrical Panel:

Select a location in your garage that is close to your electrical panel. This reduces the length of wiring required and minimizes potential electrical losses. Installing the charger near your electrical panel also simplifies the installation process.

Accessible Mounting:

Choose a location where the charger can be easily mounted and accessed. Ensure there is enough space for the charger unit and any associated wiring. Consider the height and accessibility of the charger, especially if you have a larger vehicle or plan to charge multiple cars simultaneously.

Wall-Mounted or Pedestal Charger:

Decide whether you want a wall-mounted charger or a pedestal charger. Wall-mounted chargers are fixed to the wall, saving space and providing a sleek appearance. Pedestal chargers, on the other hand, are freestanding units that can be placed anywhere within your garage. Consider your preferences, available space, and charging requirements when making this decision.

Obstructions and Safety:

Ensure that there are no obstructions or safety hazards near the chosen location. Keep in mind the proximity to water sources, ventilation, and any potential risks to prevent accidents or damage to the charger. Safety should always be a top priority.

Once you've considered these factors and chosen the prime location, it's time to move on to the installation process itself.

Installation Process:

Installing an EV charger involves several steps, from preparing the electrical circuit to mounting the charger unit. It's crucial to follow the manufacturer's instructions and, if unsure, consult a licensed electrician for professional assistance. Here's a general overview of the installation process:

Step 1: Check Electrical Capacity:

Before proceeding with the installation, assess your garage's electrical capacity. Determine whether you have enough available capacity to handle the additional load of the EV charger. If necessary, consider upgrading your electrical panel or consulting an electrician to ensure a safe and efficient installation.

Step 2: Install the Circuit Breaker:

To power the EV charger, you'll need to install a dedicated circuit breaker in your electrical panel. Follow the manufacturer's guidelines to select the appropriate amperage for the breaker, typically between 30-50 amps. Be sure to turn off the main power supply before installing the breaker to avoid electrical shock.

Step 3: Run Conduit and Wiring:

Run conduit from the electrical panel to the desired location of the EV charger. Thread appropriate wiring through the conduit, ensuring it is securely fastened and protected. The wiring size will depend on the distance between the panel and the charger, as well as the amperage requirements specified by the manufacturer.

Step 4: Mount the Charger Unit:

Once the electrical wiring is in place, mount the charger unit according to the manufacturer's instructions. Ensure it is securely attached to the wall or pedestal, using appropriate hardware and mounting techniques. Double-check the stability and alignment of the charger to avoid any issues in the future.

Step 5: Connect the Wiring:

Connect the wiring from the conduit to the EV charger unit. Follow the manufacturer's provided wiring diagram and instructions to properly connect the wires. Take extra care to tighten all electrical connections and ensure they are secure.

Step 6: Test and Verify:

After completing the wiring connections, it's essential to test the installation thoroughly. Turn on the power supply and check for any electrical faults, loose connections, or abnormal behavior. Use a multimeter or consult a professional if you're uncertain about the testing process.


Installing an EV charger in your garage is a rewarding endeavor that allows you to conveniently charge your electric vehicle at home. By understanding the different types of chargers, choosing the appropriate location, and following the proper installation process, you can set up a reliable and efficient charging infrastructure for your electric vehicle. Remember to prioritize safety and, if necessary, consult a licensed electrician for professional assistance. With your new charging station in place, you'll enjoy the convenience, cost-saving, and environmental benefits of owning an electric vehicle. Start the installation process today and embrace a greener future.
