How much to install electric car charger in garage? 2024

The electric vehicle (EV) revolution is rolling across the US, and with it comes the question of charging your electric chariot. Public charging stations are becoming increasingly available, but the ultimate convenience lies in having your own dedicated charger at home. This not only eliminates the need for frequent public charging stops, but also offers faster charging times compared to a standard household outlet. While some homeowners might opt for professional installation, the technically savvy US resident can tackle a Level 2 EV charger installation themselves. This guide will equip you with the knowledge and step-by-step instructions for a safe and successful DIY Level 2 EV charger installation in your US home.

Safety First and Planning for Success

Safety is paramount when working with electricity. Always consult a qualified electrician if you’re unsure about any aspect of the installation process. Here’s what you need to do before diving into the project:

• Know Your Limits: Assess your electrical skills and DIY experience. If electrical work makes you nervous, it’s best to leave it to a professional.
• Check Local Regulations: Building and electrical codes in your area might have specific requirements for EV charger installations. Contact your local building department to obtain any necessary permits.
• Choose the Right Charger: Select a Level 2 EV charger compatible with your car model and offering the desired charging speed. Consider factors like amperage output, weatherproofing (especially for outdoor installations), and warranty coverage.
• Plan the Installation Location: Choose a convenient location for your charger, ideally near your designated parking spot. Ensure there’s adequate clearance for the charger and the charging cable to reach your car comfortably.
• Gather the Tools and Materials: You’ll need a variety of tools and materials for the installation, including wire cutters/strippers, screwdrivers, drill with appropriate bits, cable conduit (optional), electrical tape, appropriate fasteners for mounting the charger, and safety gear like gloves and safety glasses.

Understanding Level 2 Charging

Level 2 chargers, also known as 240-volt chargers, offer significantly faster charging times compared to a standard 120-volt household outlet (Level 1 charging). While Level 1 charging might take several hours to fully charge your EV, a Level 2 charger can typically replenish your battery in a few hours, depending on the charger’s output and your car’s battery capacity.

Step-by-Step Guide: Installing Your Level 2 EV Charger

Important Disclaimer: The following instructions are for informational purposes only. Always follow the specific installation instructions provided by your chosen EV charger manufacturer.

1. Turn Off the Power: Safety first! Locate your home’s main electrical panel and shut off the power supply to the circuit you’ll be using for the charger installation. Double-check that the power is off using a voltage tester before proceeding.
2. Identify Your Electrical Panel and Circuit: You’ll need a dedicated circuit for your EV charger. If you don’t have an unused circuit with sufficient capacity, you might need to have a new circuit installed by a qualified electrician. Consult your local building department or a licensed electrician to ensure your electrical panel can handle the additional load of the EV charger.
3. Run the Charger Cable: Depending on the location of your charger and your electrical panel, you might need to run a new cable from the panel to the charger location. This typically involves drilling holes for cable routing and installing conduit for added protection (consult local codes for conduit requirements).
4. Install the Charger Bracket: Mount the charger bracket securely onto the chosen wall location using appropriate fasteners as specified in the manufacturer’s instructions.
5. Connect the Charger Cable: Following the manufacturer’s instructions, carefully connect the charger cable to the appropriate terminals in the electrical panel and the charger unit. Ensure all connections are secure and properly tightened with the recommended torque specifications.
6. Grounding the Charger: Proper grounding is crucial for safety. Connect the grounding wire from the charger to the designated grounding point in your electrical panel, following the manufacturer’s instructions.
7. Inspect and Test: Double-check all your connections for tightness and ensure no loose wires are present. Once everything is in place, turn the power back on at the main electrical panel. Consult the charger’s manual for specific testing procedures to verify proper functionality.

Additional Considerations for a Smooth Installation

• Cable Management: Organize and secure any excess cable using cable ties or wire management solutions for a clean and professional look.
• Weatherproofing (Outdoor Installations): If installing the charger outdoors, ensure it’s properly weatherproofed according to the manufacturer’s instructions and local building codes. This might involve using weatherproof conduit and sealing connections with appropriate materials.
• Permit Inspections: Once the installation is complete, you might need to schedule a permit inspection with your local building department to verify compliance with electrical codes.
• User Manuals and Safety Information: Keep the user manual and safety information for your EV charger readily available for future reference. This will be helpful for troubleshooting any minor issues or understanding proper charging procedures.
