How Long to Install an EV Charger


Electric vehicles (EVs) have revolutionized the way we commute, offering a greener and more sustainable alternative to traditional gasoline-powered cars. As more people embrace the transition to EVs, the need for efficient charging infrastructure becomes paramount. One of the common concerns among potential EV owners is how long it takes to install an EV charger at home or in commercial spaces. In this article, we will delve deep into the installation process of EV chargers and explore the various factors that can impact the installation timeframe.

Understanding the Installation Process

The installation of an EV charger involves several steps that ensure the charger is safely and efficiently connected to the electrical system. While the specific process may vary depending on the charger type, power capacity, and the existing electrical setup, here's a general rundown of what to expect during an EV charger installation:

1. Site Assessment and Planning:

Before the installation, a qualified electrician or a professional from an EV charging installation service will visit the site to assess the electrical requirements. This includes identifying the ideal location for the charger, evaluating the electrical panel capacity, determining the required circuit size, and ensuring compliance with local codes and regulations. The site assessment phase usually takes a couple of hours, as it involves careful inspection and analysis.

2. Permitting and Approvals:

Once the site assessment is complete, the next step is to obtain the necessary permits and approvals from the local authorities. This process may involve submitting the installation plans, electrical load calculations, and any other relevant documentation. The duration for obtaining approvals can vary depending on the region, as some areas may have more stringent requirements or longer processing times. On average, it may take anywhere from a few days to a few weeks to receive the necessary permits.

3. Electrical Upgrades (if required):

In cases where the existing electrical infrastructure is insufficient to handle the additional load of an EV charger, upgrades may be necessary. This can include panel upgrades, installation of dedicated circuits, or even a service upgrade. The time required for electrical upgrades can vary based on the complexity of the work, availability of materials, and the workload of the electrician. Typically, it can take anywhere from a few hours to a few days to complete the electrical upgrades.

4. Charger Installation:

With all the preliminary work completed, the actual installation of the EV charger can begin. The time required for installation depends on various factors, such as the charger type (Level 1, Level 2, or DC fast charger) and whether it is a new installation or a replacement of an existing charger. Generally, a Level 1 charger, which plugs into a standard 120-volt outlet, can be installed within an hour or two. On the other hand, a Level 2 charger, which requires a 240-volt circuit, may take anywhere from three to six hours. DC fast chargers, commonly found in public charging stations, are more complex and may require a full day or more for installation.

5. Final Testing and Commissioning:

Once the charger is physically installed, it undergoes a series of tests and inspections to ensure proper functionality and compliance with safety standards. This includes verifying the electrical connections, performing load tests, and confirming the charger's communication with the vehicle. The testing phase usually takes a few hours, depending on the complexity of the charger and the testing protocols.

The Duration of Installation

The total time required to install an EV charger varies depending on the aforementioned factors. However, it is important to note that a typical residential installation with an existing electrical system can be completed within a day or two. Commercial installations, especially those involving complex chargers or significant electrical upgrades, may take longer—sometimes a week or more.

Several factors that can influence the installation duration include:

1. Charger Type:

As mentioned earlier, different charger types have different installation times. Level 1 chargers are relatively quick and easy to install since they leverage existing electrical infrastructure. Level 2 chargers require a dedicated 240-volt circuit, which may involve more time and resources. DC fast chargers are the most time-consuming to install due to their complex power requirements, cooling systems, and additional safety measures.

2. Electrical Infrastructure:

The existing electrical system at the installation site plays a crucial role in determining the installation timeframe. If the electrical panel has sufficient capacity and the required circuit size is readily available, the installation process will be relatively straightforward and quick. However, if the panel needs to be upgraded or additional circuits need to be installed, it can significantly extend the installation duration.

3. Permitting and Approvals:

Obtaining the necessary permits and approvals can add to the installation timeline. The duration for this step depends on various factors, including the responsiveness of the local authority, the complexity of the installation, and the accuracy of the submitted documents. It is advisable to start the permitting process well in advance to avoid unnecessary delays.

4. Site Conditions:

The physical characteristics of the installation site can impact the installation duration. Access to electrical panels, proximity to the charger location, and possibilities for trenching or running conduit can affect the efficiency of the installation process. Additionally, environmental factors such as extreme weather conditions may require additional precautions and, consequently, more time.

5. Workforce and Scheduling:

The availability and workload of qualified electricians or EV charging installation professionals can influence the installation timeframe. High demand for installations or limited availability of skilled personnel can result in longer lead times. Scheduling conflicts or delays due to unforeseen circumstances can also extend the installation duration.


The installation of an EV charger is a multistep process that involves planning, permitting, electrical upgrades (if required), physical installation, and testing. While the specific timeline may vary depending on various factors, most residential installations can be completed within a day or two. Commercial installations, which often involve more complex chargers and electrical upgrades, may take longer. It is essential to consult with a qualified electrician or an EV charging installation service to accurately assess the installation timeframe based on the specific requirements and site conditions. Planning ahead and considering all the factors involved will help ensure a smooth and efficient installation process, enabling you to enjoy the convenience of electric vehicle charging at home or work.
