Yes, you can install an EV charger outside. Level 2 EV chargers designed for outdoor use can safely handle rain and other weather when properly installed. The charger must be rated for outdoor use, mounted in a suitable location, and connected to a properly sized electrical circuit that meets applicable electrical codes.
You don’t need a garage to charge an EV at home. An outdoor EV charger can be mounted beside a driveway, on an exterior garage wall, under a carport, or on a pedestal near your parking space.
Quick Takeaways
• EV chargers can be installed outside.
• The charger must be rated for outdoor use.
• Outdoor chargers can safely operate in rain when properly installed.
• Hardwired chargers are often a good choice for outdoor installations.
• Charger placement should account for weather, cable reach, and where you park.
• Your electrical panel must have enough capacity for the charging load.
Can an EV Charger Be Installed Outside?
Yes. Many Level 2 chargers are designed for both indoor and outdoor installation. The important part is choosing equipment with the proper outdoor rating and installing it according to the manufacturer’s instructions.
Common locations for an outdoor charging station include:
- An exterior garage wall
- Beside a driveway
- Under a carport
- On a detached garage
- On a pedestal near a parking space
Installing a charger outdoors does not inherently make Level 2 charging slower. Charging speed is primarily determined by the available electrical power, the EV charger, and how much AC charging power the vehicle can accept.
Can an EV Charger Get Wet?
Yes. An outdoor-rated EV charger is designed to withstand normal weather exposure, including rain.
That doesn’t mean every EV charger is waterproof or that an outdoor charger can be placed anywhere. A charger designed for outdoor use has an enclosure and weatherproofing rating intended for specific environmental conditions.
Outdoor EV charger installation in Houston should account for:
- Heavy rain
- Windblown water
- Dust and debris
- High humidity
- Direct sunlight and heat
- Areas that can collect standing water or flood
Rain is very different from submersion. Even an outdoor-rated charger should not be installed where floodwater could reach the electrical equipment.
What Weather Rating Should an Outdoor EV Charger Have?
The EV charger should carry an enclosure rating appropriate for where it will be installed. NEMA ratings are commonly used to describe how well an electrical enclosure protects against water, dust, corrosion, and other environmental conditions.
For Houston homeowners, water isn’t the only consideration. Heat, humidity, heavy rain and the Gulf Coast environment can all affect where and how electrical equipment is installed. Check the charger’s specific ratings for outdoor use rather than assuming any Level 2 charger can be installed outdoors.
Is a Hardwired or Plug-In EV Charger Better Outside?
A hardwired charger is often a good choice outside because the charging equipment connects directly to the electrical circuit without an exposed plug-and-receptacle connection.
Hardwired EV charger
- Permanent electrical connection
- Fewer exposed connection points
- Can support higher-amperage charging setups
- Does not require an outdoor receptacle for the charger
Plug-in EV charger
- Easier to remove or replace
- Requires an appropriate outdoor receptacle and enclosure
- Adds a plug-and-receptacle connection to the installation
- Must still follow the charger’s installation requirements
The better option can vary depending on the charger, charging power, mounting location, and home’s electrical system. A licensed electrician can evaluate both options before you install your charger.
Where Should You Install an Outdoor EV Charger?
The best location is usually close to where you park while keeping the charging cable easy to reach and out of the way.
Before choosing a location, consider:
- Where the vehicle normally parks
- Which side of the vehicle has the charging port
- Charging cable length
- Distance from the electrical panel
- Sidewalks and other walking paths
- Garage doors and gates
- Areas exposed to standing water
- Protection from accidental vehicle impact
- Whether you may add a second EV later
Distance from the electrical panel matters too. Installing the charger nearby may reduce the amount of wiring and conduit required. A charger farther from the house could require a longer circuit, trenching, or a more complicated route.
The closest spot isn’t automatically the best spot. The goal is to find a location that works well electrically and makes everyday EV charging convenient.
Can You Install an EV Charger in Your Driveway?
Yes. An EV charger can be installed for driveway parking when you don’t have a garage or simply don’t park your EV inside one.
If the driveway runs beside the house or garage, the charger may be mounted directly to an exterior wall. For parking spaces farther away, a pedestal-mounted charger may be an option.
The charging cable should comfortably reach the vehicle’s charging port without stretching across a sidewalk or creating a trip hazard. The charger should also be protected from standing water and possible vehicle impact.
For a detached garage or parking area away from the house, additional wiring or underground electrical work may be necessary.
Does an Outdoor EV Charger Need a Cover?
An outdoor EV charger usually does not need a separate cover when the equipment is specifically rated for the conditions where it is installed.
A garage overhang or carport can provide extra protection from direct sun and rain, but it doesn’t replace the need for properly rated electrical equipment.
Avoid putting a charger inside a homemade box or enclosure without checking the manufacturer’s requirements. EV charging equipment needs to be installed and used according to its listing and installation instructions.
Does an Outdoor EV Charger Need a Dedicated Circuit?
A Level 2 home EV charger is typically installed on a dedicated 240-volt circuit sized for the charging equipment.
The required circuit depends on how much power the charger draws. For example, a 48-amp Level 2 charger commonly uses a 60-amp circuit, while lower-powered chargers can operate on smaller circuits.
Can Your Electrical Panel Handle an Outdoor EV Charger?
Installing the charger outside doesn’t change how much electrical capacity the charger requires. Your home’s electrical system still needs enough available capacity for the additional EV charging load.
A licensed electrician may need to look at:
- Electrical service size
- Existing household loads
- Electrical panel capacity
- Charger amperage
- Required circuit size
- Load calculations
- Other large electrical appliances
- Load management options
A 200-amp panel, for example, shouldn’t automatically be assumed to have room for any EV charger. The existing electrical loads in the home matter too.
If capacity is limited, that also doesn’t automatically mean you need a full electrical panel upgrade. Lower charging amperage or an approved load management setup may be possible depending on the home and equipment.
Does an Outdoor EV Charger Cost More to Install?
It can. Outdoor EV charger installation may cost more when the charging station is farther from the electrical panel or requires additional work to reach the parking area.
Factors that can increase installation complexity include:
- Longer wiring runs
- Outdoor conduit
- Underground wiring or trenching
- Pedestal mounting
- Difficult circuit routing
- Electrical panel upgrades
- Outdoor receptacle equipment for plug-in chargers
A charger mounted on the exterior wall directly opposite an electrical panel may be relatively straightforward. Running power across a property to a detached parking area is a different project.
That’s why outdoor EV charger installation costs can vary depending on the layout of the home and where the EV owner parks.
Outdoor vs. Garage EV Charger Installation
Outdoor and garage EV chargers can provide the same Level 2 charging power. The biggest differences involve equipment ratings, weather exposure, placement, and how the electrical circuit reaches the charger.
Neither location is automatically better. The best location depends on where your EV parks, where its charging port is located, and the layout and capacity of your home’s electrical system.
