As electric vehicles or EVs become more popular, many drivers are looking into getting an EV charger for their homes. It provides the convenience of charging their cars on the property. They won’t have to look for or travel to a public charging point just to ensure their car has enough power to operate. They can also maintain an effective charging schedule for their vehicles, which preserves their batteries.
While there are many benefits to having an EV charging point installation at home, you must understand that different EV models have varying charging requirements. They can have varying battery capacity, voltage compatibility, and charging speeds. With each of these requirements, there’s an EV charger that can fit each individual’s specific needs.
So if you’re thinking about having an EV charger installed in your home, you need to ensure it’s the right one. Here are some considerations to help you come up with the best decision.
Pick the Right Type of EV Charger
When selecting an EV charger, choose one that aligns with your EV’s specifications. It’s also worth taking note of all your options. There are three main types of EV chargers available today: slow, fast, and rapid chargers. Among the three, slow and fast chargers are recommended for home use.
Slow chargers are the most accessible and cost-effective option. They have a lower charging speed, making them ideal for overnight charging or during extended periods of parking. They also come with a standard three-pin plug and require a dedicated domestic power socket.
On the other hand, fast chargers have higher charging speeds compared to slow chargers. They also tend to use a dedicated charging point. If you want a quicker turnaround for your EV’s charging sessions, this is a great choice for you.
Lastly, the rapid chargers utilise direct current (DC) to deliver a swift charge to the EV’s battery. One challenge with rapid chargers is that not all EVs are compatible with them. Also, frequent use of rapid charging may impact the long-term health of the vehicle’s battery. This is why this type of charger isn’t recommended for home use. Instead, they’re ideal for on-the-go situations.
If you want to get a general idea of an EV’s charging times, here’s an example of the charging time for a Tesla Model 3:
| Charging Method | Typically Location | Charging Time | Range/hour |
| Empty to Full | |||
| 3-pin plug | Home | 24 – 36 hours | 9 – 10 m/h |
| 3.6 kW | Home/Work | 15 – 22 hours | 14 – 17 m/h |
| 7 kW | Home/Work/Public Locations | 8 – 12 hours | 27 – 32 m/h |
| 22 kW | Work/Public Locations | 5 – 8 hours | 42 – 50 m/h |
| Charging Method | Typically Location | Charging Time | Range/hour |
| 20 – 80% | |||
| 50 kW | Public Locations | 40 – 60 minutes | 96 – 113 m/30 minutes |
| 150 kW | Public Locations | 20 minutes | 288 – 339 m/30 minutes |
Know Your Home’s Charging Capacity
Aside from choosing a charger that complements your vehicle and charging speed needs, you also need to ensure your home has the capacity for a home charging station. For example, installing fast chargers involves some electrical work. You need to set up a dedicated circuit and a charging point. You may also need to upgrade the electrical panel to ensure it can handle the charging load of the unit.
In the case of slow chargers, you must ensure that the current circuit won’t overheat or cause other safety issues. For this, consider installing a dedicated charging point to enhance safety and charging efficiency.
Either way, it’s best to consult a qualified electrician before you install an EV charging point at home. They can evaluate your home’s electrical system and determine the most efficient installation method.
Find Out the Installation Cost
Another consideration when choosing an EV charger at home is the cost, which could vary based on several factors. If you pick a slow charger, it has a lower installation cost compared to a fast charger. You also have to factor in whether or not your home’s electrical infrastructure can support the EV charger. If you need to install a dedicated circuit or upgrade the electrical panel, this can incur additional costs.
Additionally, you may need to pay professionals for installation services. Some installers offer a comprehensive package that includes the charger unit and installation, while others charge separately for labour and materials. Just make sure to keep this in mind.
While other expenses may come with installing a home EV charger, you may be able to offset the cost. In the UK, various programs offer financial support to encourage the adoption of electric vehicles. Research the eligibility criteria and application process. You can also check with the Office for Zero Emission Vehicles for the latest information on available schemes.
Consider Maintenance and Support
Understanding the maintenance requirements for your home EV charger is essential for its long-term reliability. With this in mind, make sure you have access to your EV charger’s maintenance. This includes regular inspections, software updates, and occasional cleaning.
Additionally, choose a charger from a reputable manufacturer that offers robust customer support and a warranty. This ensures that you have assistance in case you encounter any issues. It also adds a layer of confidence to your investment knowing you have someone you can count on.
Choosing the right EV charger for your home requires careful thought. From understanding your specific vehicle’s needs to evaluating the charging infrastructure at home, each decision contributes to a seamless and efficient EV ownership experience. By following this guide, you can come up with a choice that suits your needs. If you’re still unsure of what to do, you can always consult your EV manufacturer for their recommended charger.
