3 Reasons Why You Should Consider a Home EV Charging Station
- Convenience and Time Savings: Installing a home EV charging station eliminates trips to public chargers, allowing you to start each day with a full battery.
- Cost Efficiency and Energy Savings: Gives you more control over your energy use. A home EV charging station allows you to take advantage of off-peak electricity rates. Typically cheaper than public charging, a dedicated Level 2 charger can also improve charging speed dramatically over a standard outlet.
- Boost Home Value: As the number of EV owners increases, installing a home EV charging station can boost your home’s value by positioning your property as future-facing. Potential buyers see dedicated charging as a must-have feature, which can help your home stand out in a competitive market.
Choosing the Right EV Charging Station
Level 1 vs. Level 2 Chargers
EV chargers are how your vehicle connects to your home’s electrical system.
When installing an electric vehicle charging station in your home, you can choose a Level 1 or Level 2 charger. Both have either a North American Charging Standard (NACS) or a J1772 charger that is compatible with your electric car.
Level 1 chargers are the easiest to install since most EVs already come equipped with one. Nothing extra needs to be done. To charge, you simply plug one end into your wall outlet and the other into your car.
A Level 1 charger can provide a charging speed of 1.8 kWs, which means one hour of charging will give you approximately two to three miles.
Most people who frequently drive their EVs opt for the Level 2 charger due to its reduced charging time. Level 2 chargers can access charging speeds of 7.2 kW to 12 kW, depending on the neighborhood. That means for every hour of charging with a Level 2 charger, you can drive between 10 and 35 miles.
However, installing a Level 2 charger requires a licensed electrician, and the cost of installation, including electric panel upgrades and rewiring, can add up.
A Level 2 charger may also require a specialized NACS or J1772 adapter to connect your EV, and can cost anywhere from $300 to $1200.
When deciding whether to install a charging station at home, it’s important to balance your lifestyle and cost versus convenience. If you don’t drive far, use your EV for quick trips here and there, and have an outlet within easy reach, a Level 1 charger will suffice.
However, if you drive your EV frequently and need to add an outlet near your EV parking anyway, consider installing a Level 2 charger to make the installation expense worthwhile.
Smart Features and Connectivity
Some EV chargers boast smart features, including:
- App-controlled scheduling that allows you to set charging to start or stop at certain times via a smartphone. This feature can help you save money by remotely limiting charging to off-peak hours.
- Real-time monitoring to track consumption, charging status, cost, and more.
- Load balancing and dynamic power features enable the charger to adapt to your home’s energy usage to prevent overloading circuits or excessive power consumption.
- Solar and renewable integration allows some chargers to use surplus solar power at home or to integrate with solar systems.
- Open protocols and grid-integration features like OCPP (Open Charge Point Protocol) facilitate broader integration.
- Firmware updates & future proofing allow smart chargers to stay updated and adapt to newer smart-home/EV standards.
Understanding Your Home’s Electrical Capacity
Most homes only have a 100-amp circuit panel, and home wall outlets can deliver 110 volts with a current of 15 amps.
Since few homes have a 240-volt outlet, installing a Level 2 Charger requires a licensed electrician to install a special 240-volt socket. The electrician will need to run a dedicated circuit from a 200-amp circuit panel and may need to rewire the wire size and breaker to meet the EV Charger amp rating.
Rewiring can be a big undertaking and may involve digging up your yard or breaking through your concrete garage flooring to run the wiring underground safely. Before going forward with the electrical upgrade required for a Level 2 charger, some cities, including the Portland Bureau of Transportation, may also require an electrical permit.
Step-by-Step Installation Process
Depending on whether you are installing a Level 1 or Level 2 charger, the installation process can vary.
Level 1 charging uses a portable charger that plugs into a standard outlet. Though it technically is plug-and-play, with no wallbox or new circuit required. However, that doesn’t mean it’s always safe to just plug in and go.
An electrician may not be required for installation, but it is recommended to consult one before charging your EV.

Site Assessment and Planning
As mentioned, installing a Level 1 charger is as simple as plugging your EV directly into an outlet. However, it’s important to consult an electrician for a safety check, especially if:
- You’ve never checked the outlet’s rating or circuit breaker.
- You plan to charge overnight, every night, or continuously for eight to 12 hours.
- You’ve noticed any heat, tripped breakers, or flickering lights during charging.
- You want to install a new outdoor socket or run a dedicated circuit.
- Your home was built before 2000 with old or aluminum wiring or an unknown circuit layout.
During a safety check, the electrician will confirm:
- The outlet is modern, grounded, and rated for continuous load (15–20A/120V).
- The circuit is dedicated, with nothing else, such as a heater or washer, tied to it.
- The outlet and plug stay cool after an hour of charging (no discoloration or heat).
- The wiring is up to current electrical code, with proper grounding and breaker protection in place.
- The portable EVSE (your “granny charger”) is OEM-certified and has built-in fault detection (IC-CPD).
Once the above has been established, the electrician will give you the green light to plug in your EV.
An electrician is required for Level 2 charging and will make an initial visit for assessment to determine:
- Your main electrical panel capacity
- Available power supply (single-phase or three-phase)
- The distance between your panel and the desired charger location
- Parking layout & cable routing
- Whether a dedicated circuit is needed
- Your local electrical codes
Your electrician will then plan where the charger should be installed, which is typically mounted on a garage wall, carport post, or exterior wall near where you park. The location must be:
- Protected from the weather
- Reachable with Wi-Fi or Ethernet coverage for smart features
- Within safe and easy reach of cable
- Away from trip hazards or water exposure
Installing the Charger and Wiring
The electrician will perform any electrical panel upgrades and necessary rewiring to ensure the wiring supports your chosen charger rating. They install a dedicated cable and route it through conduit or cable trays between your distribution board and charger.
Then the electrician securely mounts the wallbox or pedestal and connects the circuit breaker and communication lines. Once the charger is configured, testing can be run.
Testing and Safety Checks
The electrician will perform testing, including:
- Continuity and insulation tests
- Ground fault (RCD) test
- Load and communication test
Once testing and safety checks are complete, the electrician will double-check for safety, compliance, and reliability.
Can I Install My Own EV Charger at Home?
Installing an EV charger yourself might seem like a cost-saving option, but it comes with significant considerations and potential risks. Though it may be possible in some cases, most states and counties require hiring a licensed electrician, obtaining a local permit, and having an inspection performed.
How Much Does It Cost To Install an EV Charging Station at Home?
The cost to install an electric vehicle charging station at home can range from $1,200 to $5,500, depending on how much electrical work needs to be completed.
Factors that can affect the cost of installation include:
- The charger unit
- Panel upgrades
- Re-wiring and materials; and
- Labor costs
