Electric Vehicle Charging at Home: DIY vs Professional Installation
Have you ever considered installing an electric vehicle (EV) charger at home? This article delves into the pros and cons of DIY and professional installation, helping you make an informed decision for your needs.
Introduction to EV Charging at Home
Electric vehicle (EV) charging at home is a popular choice for many EV owners. It offers convenience, control, and can significantly reduce charging time compared to public chargers. However, the process of installing an EV charger can vary greatly depending on your current electrical setup and personal preferences.
DIY Electric Vehicle Charger Installation
Many EVs come equipped with a low-power flexible cable charge adapter, which is a great alternative to a full installation. This adapter allows you to plug the charger into any standard household socket, eliminating the need to run wires from the garage into your house. The process is relatively simple, much like plugging in a kettle, but it can be a bit of a hassle. In such cases, many opt for a hard-wired external charge point.
DIY External Charge Points
DIY external charge points involve wiring up a safe wire spur from the distribution board to a connection block beside the EV. These charge points are not expensive, but in my opinion, it's penny wise and pound foolish. Safety and reliability are crucial when dealing with electrical installations.
Professional Installation Safety and Costs
For a secure and reliable installation, many local governments offer grants or tax rebates for hiring a professional to install the EV charger. A professional has the necessary experience to ensure that the work is done safely and efficiently. They also have access to better pricing for the required equipment, which can save you money in the long run.
For example, I initially planned to install a DIY charge point, but after getting a professional electrician, I learned about a much cleverer, neater way of routing the cable that would have saved a lot on materials. Practical experience truly comes in handy when dealing with electrical installations.
Comparison of Charging Times
The charging time can also vary significantly depending on the power output of the charger. For instance, with a 2KW charger, it would take approximately 30 hours to fully charge from 0%. In contrast, a 7.2KW professional charge point would take around 8.5 hours to charge, and a Tesla supercharger at a service station can charge a car under an hour. The internal charge control inside the EV limits the power intake, even if it could deliver 200KW, the car will throttle it to 100KW and then even less as it gets above 80KW.
How to Install a Home EV Charger
Installing an EV charger at home is feasible with a 120V outlet, but you might want to install a dedicated circuit breaker for the charger. Employing a professional electrician is highly recommended as they have the expertise and tools to ensure a safe and reliable installation. You do not need to run a dedicated transmission line to your house. A circuit breaker can be installed to manage the power supply safely.
Conclusion
Deciding whether to install an EV charger yourself or hire a professional depends on your comfort level with electrical work, the time you have, and the safety considerations involved. While DIY installation can be less expensive, the peace of mind and safety provided by a professional installation are crucial. For the best results and peace of mind, consider consulting a professional electrician who can provide a secure and efficient installation for your specific needs.
