Purchasing an electric car means changing not only your approach to driving but also your approach to managing your home’s energy supply system. While public charging stations meet your needs for recharging while driving, installing a home charging station is the easiest and most convenient decision for the overwhelming majority of electric car owners: your car will be fully charged by the time you wake up, with no need to stop anywhere else. Below, we explain what you should know before installing a home charging station.
Understanding EV Charger Installation Services
The concept of home charging is more complex than having a powerful outlet in the garage wall; it implies installing a dedicated electrical system. The process of professional home EV charger installation begins with a technical assessment of your current electrical system, including evaluating how much power your main circuit breaker can handle, the condition of the distribution board, and the existing system’s ability to handle an additional load.
Next, the cable-laying plan from the distribution box to the chosen installation site (usually the garage wall or an external wall near the parking lot) is designed. Home charger installation requires a dedicated circuit breaker and RCD for the charger, which will considerably reduce the risk of your home electrical system failing in the event of a malfunction. In the final stage, specialists test the device’s functionality across various modes and install additional options, such as app connectivity or integration with the home energy management system. It should be noted that quality EV charger installation services include not only the actual installation of the device on the wall but a range of preliminary and finishing tasks, including:
- technical inspection of the electric panel and wiring;
- calculating the required cable size and protective circuit breakers;
- selection of the installation location, taking into account the length of the charging cable;
- configuration and testing of the device after installation;
- training the owner to operate the station.
Choosing the Right EV Home Charger Installation for Your Property
Not all homes are created equal when it comes to their electrical capacity; thus, when choosing a station, several factors need to be considered to ensure the right decision is made and the EV charger installation is easy. First, the installation of the station is directly dependent on the unit’s power: higher-power stations recharge the car quickly but also require more intensive work on the home’s electrical system, which often means the home’s main electrical cable needs to be upgraded.
Second, the distance between the parking area and the electrical panel plays a role: the longer the cable, the higher the installation costs; moreover, there is a greater risk of cable damage, and if the installation takes place outside, weather protection is required. Finally, those with solar panels should definitely choose the “smart” stations that allow excess energy to be sent to the car without needing additional grid power.
One should think of the EV home charger installation with future needs in mind – in case a family is planning on buying another electric car in a few years, it is much better to make room for the second charging station or for a flexible one in advance, than to make changes to the wiring in the future. It can be useful to ask oneself a few questions before deciding on which specific model to choose:
- What is the highest level of power the electric panel in the house can provide?
- What is the distance between the parking spot and the electric panel?
- Is the use of solar panels or the battery pack considered?
- Is it necessary to have an application for controlling the charging process?
- Is there any intention to buy another electric vehicle in the future?
Knowing the answers to those questions will help you choose from the dozens of models available on the market.
Regulations and Standards for EV Charger Installation UK
In addition to technical characteristics, the development of home charging infrastructure will depend on national standards, which must be considered at the project’s planning stage. In the UK, EV charger installation must meet safety requirements, including the use of certified devices and protection against electric shock and grid overload.
One should pay special attention to the criteria according to which the functions available in the device should work, since the present-day requirements stipulate that any newly developed device should be equipped with “smart” functions, i.e., the opportunity to delay the procedure of charging for several hours in case of a low load of the general grid or a cheaper tariff, if such a tariff is available through an agreement with the supplier of electrical energy. In any case, EV charger installation UK must comply with applicable UK regulations and registration requirements where necessary in question in the appropriate accounting system.
This is why it is essential to entrust the installation process to professionals who are knowledgeable about both electrical engineering and modern regulations. For instance, Smart Energy Group, which is already creating solar and battery systems for houses in Wales and England, is now assisting customers with installing electric vehicle infrastructure as an integral part of a house’s energy system rather than as a separate project.
Pay attention to the following compliance requirements:
- Certification of the installed equipment.
- Availability of delayed or smart charging functions.
- Registration of the station in accounting systems, if necessary.
- Conformity of the electrical wiring to modern safety regulations.
- Presence of the protective automation specially created for the station.
Observing all formalities at the beginning of work will help to avoid any issues later on – whether it be denial of reimbursement due to a lack of compliance with requirements on the part of the equipment or difficulty with reselling the house due to a request from a potential buyer to verify the legality of the installed infrastructure.
The home charger is increasingly becoming another feature of your home, like a boiler or an air conditioner, and your professional approach to its installation will directly influence the convenience and safety of operating your electric car. Considering the peculiarities of your house and the existing regulations, you can install a system that will last for many years with no worries.
