Everything You Need To Know To Find The Best AC EV Charging Station
How to Find the Best Home EV Charger - Consumer Reports
It's possible to recharge your EV or plug-in hybrid by simply using the supplied cable that came with the car and a nearby 120-volt outlet, the kind found in most North American homes and garages. But this method is very slow; every hour of charging will add only about 3 miles of range.
For more information, please visit Sunplus.
For drivers who use their EVs daily, a 240-volt Level 2 wall charger'sometimes called electric vehicle supply equipment (EVSE)'is practically a must. It increases charging speeds to 25 miles of range per hour or more depending on the vehicle and charger combination. We think it's also a worthwhile investment because charging at home is usually much cheaper than plugging in at public charging stations. And it's clearly more convenient.
Owners of plug-in hybrids (PHEVs) may not need a 240-volt charger because PHEVs can run on gasoline when they run out of charge. And our tests have found that many PHEVs can recharge fully overnight on a 120-volt outlet. But models with larger batteries, such as the BMW X5, take more than a day; 120-volt charge times for PHEVs can be found in the Ratings and Specs section for each model.
Make sure the charger you buy has a connector that fits your vehicle. Most non-Tesla EVs manufactured before have what's called a J connector, while Tesla vehicles come with a NACS connector, short for North American Charging Standard. Converters are available, although there are currently far more options to convert from a J cord to a vehicle with a NACS outlet than in the other direction. Starting thisyear, more non-Tesla vehicles will come standard with a NACS plug, so keep that in mind if you're planning to buy a new EV in the near future.
No matter which charger you buy, make sure it has a UL and/or ETL certification mark on the unit itself. This shows that it meets safety and quality standards. Be wary of brands you haven't heard of, and avoid those with low ratings from owners. If something goes wrong with a charger, it could damage your vehicle or even cause a fire.
With that said, most chargers are pretty reliable. Fewer than 3 percent of survey respondents told us they had problems with their home chargers. The most common were the inability to connect to an app and chargers that stopped charging before the vehicle battery was full.
When shopping for a home charger, consider the following factors, roughly in descending order of importance:
Amperage: We've used 40- and 50-amp chargers, but some homes can accommodate 80-amp chargers. Although they cost more, they can nearly double the speed at which some cars charge at home.
Cable length: The length of the charging cable affects where you can mount the EVSE and how easy it will be to reach the car's charging port. Remember that your next EV may have a charging port in a different location, and you'll want to be able to reach it. Most cables are between 20 and 25 feet long, and we recommend going for the longest you can afford, usually 25 feet.
Cable management: It's handy to have a hook to wrap the unused portion of the cable around. Otherwise, if the cable is scattered, it adds clutter in the garage, collects dust, and might cause someone to trip over it. The ability to place the holster for the connector away from the unit might add flexibility in a tight single-car garage. If your connector doesn't come with a hook, a wall-mounted holder for a garden hose will do the trick and can be found at any hardware store.
Ease of plugging/unplugging: We like to see a high-quality, substantial coupler that lets you smoothly and effortlessly plug and unplug into and out of the car's port. A solid and secure holster is an advantage, and it gives you confidence that the coupler will stay secure. One is usually included with top brands.
Location: Where you install your charger could determine how easy it is to plug in your car and how much the installation costs. If you have to dig a trench for wiring, even a few feet can add hundreds of dollars. Even indoors, you can save money by installing a charger closer to where electrical service already exists. Ideally, you'll want to install your charger so that a cable can easily reach the car's charge port whether it's on the front, rear, left, or right of the vehicle. Otherwise, you might have to drag the cable across the car's roof. Consult an electrician before getting your heart set on where a charger can go.
Size: Once you've determined where a charger should go, measure to see how much space you have. A wide wall charger or a thick one that sticks out far from the wall may encroach on space or your flexibility in placing it in the garage. Look at all placement options. For instance, a narrow unit might fit on the small strip of wall between two garage doors.
Ability to delay charging via app: Many cars allow you to control the charging time from within the car or via an app, so you can benefit from cheaper off-peak electricity costs, depending on your utility company. If your car doesn't have this feature, consider a charger that does. Remember that this functionality may not work if the company that manufactured the charger discontinues support. (That's what happened when the company that made JuiceBox chargers left the U.S. Owners could still charge their cars, but they lost access to the JuiceBox app.
Weatherproofing (optional): For those without a garage, look for a charger that can stand up to inclement weather. Most are claimed to be weatherproof by manufacturers. If you plan to install yours outside, we recommend finding a charger with a NEMA rating of 3, which is a standard set by the National Electrical Manufacturers Association that defines how resistant a product is to environmental hazards. A NEMA 3 rating, which is common on most home chargers, means they're resistant to nearly all ambient temperatures in addition to the rain, sleet, and snow that the average U.S. consumer would face. The Grizzl-E has a NEMA 4 rating, which means it's even more watertight. Note that a charging cable can become brittle in extremely cold weather.
How Many Amps Do You Need?
The higher the amperage of a home charger, the faster the charge, but just how fast depends on the electrical system of your car and your home. First, you need to determine how much amperage your home's electrical system can handle. An electrician can help you figure that out. We recommend at least a 32-amp charger.
Then check to see what kind of charge your vehicle can accept, a spec that can be found on CR's vehicle model pages. For instance, a Hyundai Ioniq 5 has an 11 kW onboard charger, so it can benefit from a 48-amp charger. A Toyota bZ4X only has a 6.6 kW onboard charger, so it won't benefit from charging at higher than 30 amps. Several newer EVs are capable of charging at 60 to 80 amps. For applications above 48 amps, it's recommended that the EVSE is hardwired as opposed to plugged into an outlet like a clothes dryer. Don't be swayed by low-priced chargers that might charge less quickly. We recommend avoiding 16-amp chargers entirely. Onboard charger size and amperage information can be found in the Ratings and Specs section for the EV you're interested in.
Should You Hardwire or Plug In Your Charger?
It depends. A plug-in type benefits from portability. These chargers can be readily replaced as needed, and they're easy to take with you when you move or even when you're on vacation if you rent a home. But a plug-in charger may not be able to run at as high an amperage as a hardwired model, so it may charge a little bit slower. Some high-amperage chargers require hardwiring.
Should You Buy a Smart Charger?
Not necessarily. Most EVs, like those from Nissan shown below, allow you to view charging status and get notifications through the car manufacturer's app, and smart WiFi-connected chargers tend to cost more up front. But many utility companies offer rebates only on WiFi-connected models, which can cover the added expense.
Do You Have Frequent Power Outages?
If you live in an area that has frequent power outages, charging might not resume once the power is back on, and you could be surprised to find out that your EV isn't sufficiently charged when you're ready to drive. Some chargers and vehicles require the user to manually restart the charging session after a power outage. In those situations, it may be helpful to get a smart charger that can send an alert to your if charging is interrupted, or buy an EV with a similar feature. If you have a generator for your home, consult an electrician to make sure it can handle charging an EV when the power is out.
kW: Kilowatt, or one thousand watts. This is the unit for electrical power. Multiply volts (240) by the amperage rating of your charger and divide by 1,000 to determine how many kW can be sent to your vehicle.
kWh: Kilowatt hour. A unit of energy that's stored inside a battery, expressing the battery's capacity. Think of a battery's kWh capacity as the equivalent of how many gallons of gas a tank can hold.
Level 2 charger: A 240-volt charger that can be installed at home or in a public place. It adds 20 to 40 miles of charge per hour and can fully charge an EV's battery overnight. Public versions can be free or cost money depending on the location and provider.
NEMA: National Electrical Manufacturers Association. A trade group that sets standards for electrical products, such as types of plugs.
Type 1 connector: Also called J, this is a type of charger plug used on many American and European EVs and PHEVs that aren't made by Tesla.
NACS (North American Charging Standard) connector: Also called J, this is a combination AC/DC charging plug used on Tesla vehicles that's being introduced on EVs from other brands. Adapters exist to convert between NACS and CCS.
UL Listed: It's wise to pick an EVSE that's UL or ETL (Edison Testing Laboratories) listed, which indicates it complies with safety standards established by nationally recognized testing labs. Every charger featured here has such a safety rating, indicated by a seal on the box, the owner's manual, or the unit itself.
Voltage: A measure of the force that moves electrical current. At the same amperage, a 120-volt outlet moves electricity more slowly than a 240-volt outlet, so an EV will charge less quickly when plugged into a 120-volt outlet. That's why you have to install a special kind of outlet to plug in a Level 2 EV charger.

What Are the Types of EV Chargers and the Charging Modes?
Chargers and charging modes can significantly influence the charging speed of your electric cars, which is why understanding them is crucial. Let's dive into the different types of EV chargers and charging modes to see how they affect the charging process.
Levels of EV Chargers
There are three primary levels of EV chargers: Level 1, Level 2, and DC Fast Charging. Each level offers different speeds and is suited for various scenarios.
Level 1 Charging
Level 1 charging uses a standard 120-volt household outlet. This is the slowest charging option, providing about 2-5 miles per hour. It's perfect for short daily commutes and can be a convenient backup option when other chargers aren't available.
Level 2 Charging
Level 2 chargers use a 240-volt outlet, similar to those used for large home appliances. They are commonly found in homes, workplaces, and public charging stations. Level 2 charging offers a faster rate, providing about 10-25 miles per hour, which means a full charge typically takes 4-8 hours.
DC Fast Charging
DC fast chargers use direct current (DC) and are designed for rapid charging. These chargers bypass the vehicle's onboard AC charger and deliver power directly to the battery. DC fast chargers can add 60-100 miles of range in just 20 minutes and can charge an EV up to 80% in about 30 minutes. They are usually located at public charging stations along highways and in urban areas, making them ideal for long-distance travel and quick recharges on the go.

Different charging modes can also affect how efficiently you charge your EV. These modes are categorized as Mode 1, Mode 2, Mode 3, and Mode 4.
Mode 1 Charging
Mode 1 is the simplest and slowest method, using a standard household socket without any communication between the EV and the charge point. This mode is rarely used due to safety concerns and its slow speed.
Mode 2 Charging
Mode 2 also uses a household socket but includes an In-Cable Control and Protection Device (IC-CPD) for added safety. It can provide up to 3.7 kW of power, making it suitable for overnight charging at home.
Mode 3 Charging
Mode 3 involves a dedicated EV charging station connected to an AC power source. It can deliver up to 22 kW and includes safety features and communication capabilities to monitor and manage the charging process. This mode is commonly used in public charging stations and for home wall box installations.
Mode 4 Charging
Mode 4 is used for DC fast charging, bypassing the vehicle's onboard charger and delivering power directly to the battery. This mode supports very high power levels, enabling rapid charging, typically found at public fast charging stations along highways.
AC Charging vs. DC Fast Charging
AC charging, used in Mode 1, Mode 2, and Mode 3, involves converting AC to DC within the vehicle's onboard charger. It is generally slower but is suitable for regular, overnight charging. DC fast charging (Mode 4) provides direct current directly to the battery, significantly speeding up the charging process. However, frequent use of DC fast charging can impact battery health due to the charging curve, which slows down the charging speed as the battery approaches 80% to prevent damage. For deeper understanding, here is a comprehensive comparison of AC charging vs DC charging.
What Is the Charging Curve?
The charging curve is intimately associated with charging levels, as the charging level determines the power and speed at which an electric vehicle (EV) battery is charged, directly influencing the shape of the charging curve. At lower charging levels, such as Level 1 and Level 2, the charging power is relatively low, resulting in a more gradual and consistent charging curve. In contrast, Level 3 (DC fast charging) delivers high power, creating a more dynamic charging curve with distinct phases: a rapid initial charging phase (constant current) followed by a slower phase (constant voltage) as the battery approaches full capacity. That is to say, higher charging levels lead to faster initial charging but require careful management to prevent battery damage as the charge progresses.

- Regular Maintenance: Keep your EV software updated and follow the manufacturer's maintenance recommendations. Regular check-ups can help detect potential issues early.
What Factors Can Affect the Range of My Electric Car?
You might think that two identical models of EVs, both with a full charge, would travel the same distance, but that's not always the case. Even with equal electricity, the range can vary significantly due to several factors. It's not just about the battery size or the charge level; how you drive, the weather, and the terrain all play crucial roles. Understanding these factors can help you optimize your EV's range and get the most out of every charge. Let's delve into what can affect your EV's range and how you can manage these variables to maximize your driving distance.
Driving Habits
Your driving habit has a direct impact on your EV's range. Rapid acceleration, high speeds, and aggressive driving can significantly reduce your range. When you accelerate quickly, your vehicle consumes more energy to overcome inertia. Similarly, driving at high speeds increases aerodynamic drag, which requires more power from the battery. Aggressive driving, with frequent stops and starts, also wastes energy. On the other hand, smooth, steady driving at moderate speeds is much more energy-efficient. By accelerating gently and maintaining a consistent speed, you can extend your EV's range.
Weather Conditions
Weather can also play a significant role in determining your EV's range. Extreme cold or heat can reduce battery efficiency. In cold weather, the chemical reactions inside the battery slow down, reducing its ability to hold a charge and deliver power efficiently. Additionally, heating the cabin in cold weather draws energy from the battery, further reducing range. In hot weather, the battery management system uses energy to cool the battery and the cabin, which can also decrease range. Preconditioning your car while it's still plugged in can help mitigate these effects by bringing the battery and cabin to an optimal temperature before you start driving.
Terrain
The type of terrain you drive on can affect your EV's range as well. Driving on hilly or mountainous terrain uses more energy than flat roads. When climbing hills, the motor has to work harder to overcome gravity, consuming more power. On the other hand, driving downhill can regenerate some energy through regenerative braking, but it's usually not enough to offset the energy used to climb. Planning your routes to minimize steep climbs can help conserve battery power.
Climate Control
Using the air conditioner or heater can drain your battery quickly. Climate control systems are significant energy consumers in EVs. In summer, cooling the cabin requires power from the battery, while in winter, heating the cabin can consume even more energy. To minimize this impact, precondition your car while it's still plugged in to reach a comfortable temperature before you start driving. Additionally, using seat heaters instead of cabin heating can save energy and extend your range.
