Can a Residential EV Charger be Installed Without Professional Hard Wiring?
Electric vehicle (EV) owners often wonder about the convenience and feasibility of installing an EV charger without professional hard wiring. This article explores both options and provides insights into the advantages and disadvantages of each approach.
Low-Power Flexible Charger Adaptor
Many new EVs come with a flexible cable charge adaptor that allows users to plug into any common household socket. This setup is straightforward; you simply plug the charger into an outlet and connect it to your vehicle. The low power output (often around 2 kW) makes this method suitable for slow charging needs. To fully charge an EV with a flexible cable adaptor can take up to 30 hours, which is far from ideal for many users who need to recharge quickly.
The DIY Approach
While the low-power flexible cable is relatively hassle-free, some DIY enthusiasts might consider wiring up a safe spur from the distribution board to a connection block beside the EV. This do-it-yourself (DIY) solution requires knowledge of electrical systems and safety protocols. The charge points can be acquired relatively inexpensively, but the potential risks and the lack of professional guarantees make this approach less appealing for most.
The Professional’s Perspective
A professional electrician can safely and efficiently install an external charge point, ensuring that the installation meets all necessary safety and compliance standards. Here are some reasons why it might be worth considering a professional installation:
Guaranteed Safety: A professional ensures that the installation is safe, compliant with local regulations, and can help avoid potential electrical hazards like short circuits or unsafe wiring. Insurance Coverage: In the unlikely event of a fire or other electrical accident, a professional installation can provide coverage under insurance policies. Cost Savings: Professionals often have bulk purchase agreements that allow them to purchase the necessary equipment at a reduced cost. Additionally, the cost of professional labor is often covered or partially covered by grants or tax rebates. Neatness and Efficiency: Experienced electricians can route cables in a way that minimizes material costs and ensures a clean, professional installation.Comparison of Installation Methods
Installation Method Setup Time Charging Time from 0% Power Output Low-Power Flexible Cable Straightforward 30 hours 2 kW DIY External Charge Point DIY skills required Varies (typically 8-12 hours) 3-7.2 kW Professional External Charge Point Professional knowledge required 8.5 hours 7.2 kWA professional installation typically provides a 7.2 kW charge point, which significantly reduces the charging time to around 8.5 hours. For fast charging needs, public charging stations like Superchargers at service stations can provide even quicker recharges.
Conclusion
While a DIY approach to installing an EV charger might be tempting for cost-savings and convenience, it is often more practical and safer to hire a professional electrician. Professional installations offer the added benefits of safety, compliance, insurance coverage, and cost savings. An experienced electrician can also provide a more efficient and aesthetically pleasing installation, which can add value to your home. Moreover, professional services are often partially covered by grants or tax rebates, making the initial investment more accessible.
Ultimately, the choice between DIY and professional installation depends on your comfort level with electrical work, your budget, and your willingness to accept the risks associated with a non-professional installation. For the vast majority of EV owners, a professional installation provides the best balance of convenience, safety, and cost-effectiveness.
