Having an EV charging station at home makes life a lot more convenient. You can replenish your vehicle’s charge when you get home. If you drive a lot, you can charge to a full level overnight. EV drivers who charge at home generally pay less in charging costs while owning their electric vehicle. This is because they use public charging stations as a secondary option rather than their primary charging source. Choosing an EV charging station is a big decision. There are many choices to make, and making the right ones is key to maximizing your investment.
Fixed vs. Portable Chargers
An important consideration is how your charging station will connect to your home’s electrical system. Before installing, schedule a professional inspection to ensure your electrical panel can support an EV charger. Homeowners in older homes may need to replace their panels or upgrade them. That can include adding surge protection and an additional 240-volt line.
There are two main types of chargers: fixed and portable. The industry also calls fixed charging stations hardwired because an electrician will connect it directly through the panel. There are several advantages to this approach. Fixed chargers provide higher charging speeds, more consistency, and lower susceptibility to power surges compared to portable chargers.
Portable systems plug into an outlet, and there are advantages to this approach. Some drivers who travel like to have a mobile charger. Chargers that plug in are easy to unplug and take with you. This option is also ideal for renters or homeowners planning to relocate, as the charger can move with you.
Considering Outdoor Installation Options
Homeowners typically install their EV charging station in their garage, where it is protected from the elements. Still, outdoor installations are an option. Perhaps you don’t have a garage or use it for other purposes. The main consideration in that case is weatherproof availability.
Outdoor-rated EV chargers are designed with additional sealing to protect them from rain, wind, and sunlight, ensuring durability and performance. They’re often more resistant to sunlight exposure and can handle that additional heat without overheating.
Lockable Charging Stations
Another important consideration is locking the charger. Local ordinances may require this feature to avoid accidents involving children and pets. Insurance companies will often require it as well. Even if there isn’t a requirement, you may want the peace of mind that comes with that upgrade. Some EV chargers include built-in locking mechanisms, while others require a lockbox that can be installed by your electrician.
Small-Scale Solar Options
Another advantage of outdoor installation is the ease with which you can add a solar panel. That solar panel can connect to a battery that stores the sunlight’s energy. While this may not meet all your charging needs, it can significantly reduce energy costs and your carbon footprint.
Level 1 vs. Level 2 Chargers
There are two charging levels provided by home EV charging stations: Level 1 and Level 2. Level 1 chargers are often more affordable, but they charge at a much slower rate. That may be all right if you’re charging a PHEV with a relatively small battery. If you have an electric vehicle, it can take days for a Level 1 charger to charge from 0% to 100%. The Level 2 charger, on the other hand, will be able to charge that same vehicle overnight.
Charging Speed
Most Level 1 chargers provide 1.2 kilowatts an hour. Level 2 chargers can range anywhere from about 6.2 to 19.2 kW. Make sure to look at the charging speed a system provides, as this can make a big difference. The difference between a 6.2-kW and 19.2-kW charger is three times the charging time. However, check your EV’s maximum charging capacity before selecting a high-powered charger, as using a 19.2-kW charger with a vehicle that caps at 12.2 kW may not be cost-effective.
Brand, Reliability, and Warranty
The growing rate of electrical vehicle purchases has led to a flood of cheaper systems on the market. Be careful which brand and model you choose. Discuss your options with a licensed electrician and look for brands with a reputation for quality and dependability. Research brand reputation and reliability for the model and product line.
The other thing to consider is the warranty. Determine what it covers and for how long. Find out if there are responsibilities you must abide by, such as annual maintenance. If you have options to expand and extend the coverage, explore that fine print as well.
Connector Compatibility
Automakers primarily use two plugs for the U.S. market. Most people use the SAE J1772 plug, which the industry also calls the J plug or Type 1 connector. The main alternative to the J plug is the Tesla plug. This has traditionally been exclusive to Tesla vehicles, but that is changing.
Some manufacturers, like General Motors, have announced plans to transition from the J plug to the Tesla plug. Simply choose a charger with the plug you need. Most brands offer versions of their charging stations with each. Also, don’t worry about the choice long term. If you switch vehicles, swapping to a different plug is a relatively simple task for an electrician.
Cable Options
There are dual chargers available. These are a great choice for homes with multiple EVs. You can even have a J plug on one side and a Tesla plug on the other. For cable management, consider options like reels or wall-mounted organizers to keep cables tidy and accessible. As for length, choose only what you need. Too much cable can often prove to be a hassle.
Smart Features
Smart features are common with modern EV charging stations. If you want app-based remote monitoring and control, you’ll need a Wi-Fi charger. These systems can often push notifications, such as to alert you that charging is complete. Other smart features include usage reports, scheduled charging to optimize energy rates, and seamless EV integration for advanced automation.
Rebates and Tax Credits
ENERGY STAR is a U.S. EPA program through which it certifies appliances for energy efficiency. Selecting an EV charging station with the ENERGY STAR label gives you peace of mind. The charger will perform at the level the manufacturer promises. Another reason to target an ENERGY STAR unit is that it’s a requirement of most energy incentives.
For example, the federal tax credit covers 30% of the installation cost, up to $1,000, for qualified systems. At the state level, there are often rebates available through local utility companies and private groups. To find the rebates available in your area, you can search by zip code through the EPA website.
