How Long Does It Take to Install an EV Charger?
The installation time for an EV (Electric Vehicle) charger
can vary depending on several factors, including the complexity of the
installation, the type of charger, and any required electrical upgrades. Here's
a comprehensive overview of the factors that influence the installation time
and what you can generally expect.
Factors Influencing Installation Time
- Type
of EV Charger
- Slow
Chargers (3.6 kW): These are generally simpler to install and require
less time.
- Fast
Chargers (7 kW to 22 kW): The most common for residential
installations, these may require additional time depending on electrical
requirements.
- Rapid
Chargers (43 kW and above): Typically used for commercial settings;
these installations are more complex and time-consuming.
- Electrical
System Assessment
- Existing
Electrical Capacity: If the existing electrical panel has sufficient
capacity and spare circuit breaker slots, the installation will be
quicker.
- Electrical
Upgrades: If upgrading the electrical panel or installing a new
circuit is necessary, this will add time to the installation process.
- Site
Conditions
- Proximity
to Electrical Panel: Installations closer to the main electrical
panel are generally quicker. More distant locations require additional
cabling, which takes more time.
- Mounting
Surface: Installing the charger on an easily accessible wall or
mounting post can speed up the process. Complex mounting conditions or
outdoor installations may take longer.
- Permits
and Approvals
- DNO
Approval: For high-powered chargers, approval from the local
Distribution Network Operator (DNO) may be required, potentially delaying
the installation.
- Building
Regulations Compliance: Ensuring compliance with Part P of the
Building Regulations and obtaining necessary permits might add some
additional time.
Typical Installation Timeline
- Initial
Assessment and Preparation
- Site
Survey: Typically takes about 1-2 hours. The electrician assesses the
electrical system, potential installation site, and any necessary
upgrades.
- Quoting
and Permits: Getting a quote and applying for any required permits
can take from a few days to a couple of weeks, depending on local
regulations and DNO approval.
- Installation
Process
1.
Simple Installation
- Duration:
2-4 hours.
- Specifics:
For installations where the charger is close to the electrical panel,
the electrical system has sufficient capacity, and no complex cabling or
mounting is required.
2.
Typical Residential Installation
- Duration:
4-8 hours.
- Specifics:
Includes installing a dedicated circuit, potential small upgrades to the
electrical panel, and standard cabling and connections.
3.
Complex Installation
- Duration:
1-2 days.
- Specifics:
For installations requiring significant electrical upgrades, longer
cabling runs, or complex mounting conditions.
Steps Involved in Installation
- Electrical
System Evaluation
- Capacity
Check: The electrician evaluates whether the main service panel can
handle the additional load from the EV charger.
- Upgrades:
If necessary, they will plan and execute upgrades to the electrical
system to ensure safety and compliance.
- Mounting
the Charger
- Wall
or Post Installation: Securely mounting the charger to a wall or
dedicated post, ensuring it is easily accessible and properly positioned.
- Weatherproofing:
For outdoor installations, ensuring the charger is weatherproof and
properly sealed.
- Wiring
and Connections
- Running
Cables: Running electrical cables from the main panel to the charger,
making all necessary connections.
- Circuit
Breaker Installation: Installing a dedicated circuit and appropriate
circuit breakers to protect the installation.
- Earthing
and Bonding: Ensuring proper earthing and bonding to enhance safety.
- Testing
and Commissioning
- Safety
Tests: Performing necessary safety tests to ensure the charger is
functioning correctly and safely. This includes checking grounding,
insulation resistance, and RCD functionality.
- System
Commissioning: Final checks and commissioning of the charger.
- Certification
- Electrical
Installation Certificate (EIC): Providing necessary certification to
confirm that the installation complies with safety standards and
regulations.
Conclusion
The time required to install an EV charger can vary widely
depending on several factors, including the type of charger, the complexity of
the installation, and the condition of the existing electrical system. On
average, a straightforward residential installation can take between 2 to 8
hours, while more complex installations may require up to 1-2 days. Initial
assessments, potential upgrades, and obtaining necessary permits may also add
to the total timeline. Ensuring the installation is carried out by a qualified
electrician ensures safety, compliance, and optimal performance of the EV
charger.
