How to Choose Between Indoor and Outdoor EV Chargers

Indoors, it is usually easier to connect to an existing power source without requiring additional conduits or extensive wiring. This reduces complexity and installation time.

Walls and columns in garages provide natural mounting points for the charger, eliminating the need for pedestals or additional structural supports.

An indoor installation shields the charger from harsh weather conditions, contributing to its longevity and reliability.

While indoor installations are straightforward, they do require adequate space. If parking indoors isn’t an option, chargers can still be mounted indoors with cords routed outside for convenient access.

Outdoor installations offer flexibility for those without indoor parking spaces but require additional planning to ensure safety and durability. Key factors include:
 

Outdoor chargers are built to withstand rain, snow, and temperature fluctuations. Proper weatherproofing of the unit and connections is essential to maintain performance.

Installing outdoor chargers may involve tasks like trenching, conduit installation, or even constructing a concrete pad to securely mount the pedestal. Repairs to concrete or asphalt around the installation site may also be needed.

Consulting with a qualified EV charger installer ensures compliance with local regulations and a seamless setup process.

Although more labor-intensive, outdoor installations enable greater accessibility, especially in residential or commercial spaces where parking is located outside.

Indoor EV chargers are highly recommended by industry experts for residential use. Here’s why they are an excellent choice:

Indoor chargers are safe from environmental factors like rain, snow, extreme temperatures, and potential damage from animals or vandalism. This protection extends the lifespan of the charger.

Indoor installations often require less maintenance due to their protected environment. Additionally, the streamlined installation process reduces costs.

Even if a vehicle is parked outdoors, cords can be routed outside for convenience without exposing the charger to weather-related wear and tear.

Outdoor EV chargers are equally robust and come with their own set of benefits, particularly for those who park outside.

Modern EV chargers are designed to endure extreme weather conditions, with waterproof cords and watertight seals ensuring uninterrupted operation.

Outdoor chargers can be installed closer to vehicles, eliminating the need to run long cords from indoor spaces. This proximity enhances user convenience and reduces clutter.

Outdoor chargers can be installed in various settings, including driveways, carports, and commercial parking areas, making them accessible for a wider range of users.

When deciding between indoor and outdoor EV chargers, evaluate these important factors:

If your vehicle is parked indoors, an indoor charger is the obvious choice. For outdoor parking, installing the charger near the vehicle is more practical.

Indoor installations are typically more affordable due to reduced infrastructure requirements. Outdoor installations may require additional work, such as trenching or pedestal mounting, which can increase costs.

In regions with extreme weather, an indoor charger provides added protection. However, outdoor chargers are built to withstand harsh climates and offer reliable performance.

Limited indoor space may necessitate an outdoor setup. Conversely, a lack of outdoor parking can make an indoor charger more suitable.

Consider how often and for how long you charge your vehicle. For frequent, short charging sessions, proximity to the parking space is critical.

Indoor vs. Outdoor: A Comparative Look

 

Is it Safe to Charge My Electric Vehicle Outdoors?

If you're considering installing an outdoor charging station near your home, it's natural to feel some apprehension about potential risks to your vehicle or safety. However, outdoor EV charging is designed to be secure and reliable when proper precautions are taken.

Safety Considerations for Outdoor EV Charging

Outdoor EV chargers offer convenience and accessibility, but it's important to handle them safely. Here are a few key tips:

Avoid Contact with Conductive Objects

Don’t park your EV near large metal objects, such as fences or garbage cans. These objects can act as conduits for stray electrical currents if a fault occurs.

Inspect for Damage

Regularly check the charger and its cables for wear, cracks, or other damage that might expose electrical components.

Ingress Protection (IP) for Outdoor Chargers

Modern outdoor EV chargers are built to withstand harsh conditions, including rain, snow, and extreme temperatures. These chargers typically feature high ingress protection (IP) ratings, ensuring resistance to water and dust.

However, the station’s inlet pipes and connectors can still be susceptible to physical impacts or surges. To mitigate these risks, choose a charger made from durable materials that has undergone rigorous testing for impact and fire resistance.

Compliance with Regulations

Regulations for outdoor EV charger installations vary across cities, states, and countries. Always consult local authorities and secure the necessary permits before proceeding with installation.

Permit Requirements

Some municipalities require a permit process for residential or commercial EV charger installations. Ensure all approvals are in place before starting the project.

Staying Updated

Regulations may change, so it’s a good idea to periodically review local laws to remain compliant.

Outdoor EV charging is safe and reliable when appropriate measures are taken. By following safety tips, choosing high-quality chargers with proper ingress protection, and adhering to local regulations, you can enjoy the convenience of charging your vehicle outside with peace of mind.

Where Should You Install Your EV Charger: Indoors or Outdoors?

The choice between indoor and outdoor EV chargers depends on your priorities, budget, and location. Here's what you should consider:

Indoor Chargers

Indoor chargers, particularly in a garage, offer convenience and protection. These chargers are shielded from weather conditions, reducing wear and extending their lifespan. However, they are generally more expensive to purchase and install. For a Level 2 charger—the most common option—you’ll need a dedicated 240V circuit, which requires professional electrical work and can cost several thousand dollars.

Outdoor Chargers

Outdoor chargers are often more affordable and easier to install, with many models designed for do-it-yourself setups. However, exposure to rain, snow, and other elements can lead to rust and wear over time. If you live in a region with mild, temperate weather or don’t mind periodic maintenance, an outdoor charger could be a cost-effective solution.

Key Consideration

If budget isn't a concern or you prioritize durability and reliability, an indoor charger is a solid choice. For those in areas with favorable weather or looking for a budget-friendly option, an outdoor charger might be the better fit

Conclusion

Choosing between indoor and outdoor EV chargers ultimately depends on your specific needs, space constraints, and budget. Indoor chargers offer enhanced protection and cost efficiency, while outdoor chargers provide greater flexibility and accessibility.

For a seamless installation, consult with a professional EV charger installer to assess your location, ensure compliance with local regulations, and choose the best solution. By selecting the right charging setup, you’ll enjoy the convenience of EV ownership while supporting a more sustainable future.
