Can EV Chargers Be Installed Outside?
Yes, EV chargers can be installed outside, and many are
specifically designed to withstand various environmental conditions. Outdoor EV
chargers are built to be robust, weather-resistant, and safe for outdoor
installations. However, there are several important considerations and steps to
ensure a safe and effective installation. Here's a detailed overview of
installing EV chargers outside:
Weatherproof and Durable Design
- Weatherproof
Enclosures
- IP
Ratings: Outdoor chargers typically come with an IP (Ingress
Protection) rating that indicates their resistance to dust and water.
Look for chargers with at least an IP54 rating for general weather
resistance, with IP65 or higher being ideal for more exposed locations.
- Materials:
High-quality enclosures made from durable materials like polycarbonate or
rust-resistant metals ensure longevity and resistance to weather damage.
- Sealed
Units
- Protection:
Chargers have sealed units to prevent water and debris ingress,
protecting internal components from moisture, dust, and other
environmental factors.
- Built-In
Drainage
- Water
Management: Many outdoor chargers feature built-in drainage channels
to divert water away from the device, reducing the risk of water damage.
Installation Considerations
- Location
Selection
- Accessibility:
Choose a location that is easily accessible for your vehicle, such as a
driveway or garage wall. Ensure there's enough space for the charging
cable to reach the vehicle’s charging port without creating trip hazards.
- Mounting
Surface: Install the charger on a sturdy surface, like an external
wall or a purpose-built post. Ensure the mounting is secure and level.
- Proximity
to Electrical Supply
- Minimize
Distance: Position the charger as close to the main electrical panel
as possible to reduce the length of electrical cable runs, which can help
lower installation costs and reduce voltage drop.
- Wiring
and Load Capacity: Ensure the existing electrical system can handle
the additional load from the EV charger. Upgrading the electrical panel
or adding a dedicated circuit might be necessary.
Professional Installation
- Hire
a Certified Electrician
- Certification:
Ensure the electrician is certified and experienced in EV charger
installations. They should be registered with a recognized certification
body such as NICEIC, NAPIT, ELECSA, or STROMA Certification.
- Compliant
Installation: The electrician will ensure that the installation
complies with local building regulations, including Part P of the
Building Regulations in the UK, and adheres to the IET Wiring Regulations
(BS 7671).
- Permits
and Approvals
- Building
Control Notification: For installations requiring significant
electrical work, it might be necessary to notify local building control
authorities or obtain specific permits.
- DNO
Approval: For high-power chargers, notify the local Distribution
Network Operator (DNO) to ensure the installation will not adversely
affect the local grid.
Safety Features
- RCD
Protection
- Residual
Current Device: Installing a Residual Current Device (RCD) provides
protection against earth faults and ensures the safety of the
installation.
- Earthing
and Bonding
- Proper
Earthing: Ensure the charger is correctly earthed to prevent electric
shocks. The electrician will check and upgrade the earthing system if
necessary.
- Bonding:
Additional bonding of metallic parts may be required to maintain safety
compliance.
Maintenance and Care
- Regular
Inspections
- Check
for Damage: Periodically inspect the charger and its components for
signs of wear or damage that might compromise its weatherproof features.
- Seal
Integrity: Ensure that all seals and protective covers are intact and
functioning.
- Cleaning
and Upkeep
- Keep
Clean: Regularly clean the charger using a damp cloth to remove dirt
and debris. Avoid using harsh chemicals that could damage the enclosure.
- Prevent
Blockages: Ensure drainage channels are clear and not blocked,
allowing water to flow away from the charger.
Conclusion
EV chargers can indeed be installed outside, provided they
are weatherproof and designed to withstand the elements. Key considerations
include choosing a charger with a suitable IP rating, selecting an accessible
and appropriate location, and ensuring proper installation by a certified
electrician. Regular maintenance and inspections will help ensure the charger
remains in good working condition. By following these guidelines, you can
safely and effectively install an outdoor EV charger to provide convenient and
reliable home charging for your electric vehicle.
