Similar to charging your phone, there are various methods available to charge an electric vehicle.1

Charger output plays an integral part in charging times.

Some drivers opt to install home chargers so they can plug their EV in at night or when at work; others utilize public EV charging stations.

Level 1

Electric vehicle charging levels are classified into three levels: Level 1, 2, and 3 (which is also known as DC Fast Charging or Tesla Supercharging). A level 1 charger features a plug that looks similar to that found in most households’ power cords; its other end connects directly to an EV’s charging port – these chargers are commonly used by EV drivers for charging at home, work, or public places.

Level 1 chargers operate on 120 volts, making them compatible with many existing residential electrical circuits. You can easily install one in garages, carports and parking lots of apartment complexes, condominiums or workplaces; plus it’s even offered at airports, hotels, restaurants or shopping centers!

Level 1 chargers typically add about five miles to an EV’s range per hour, making it sufficient for most commuters or running errands in their EV, but may not provide fast enough charging speeds for longer commutes.

There are, however, drawbacks associated with Level 1 charging outlets; most EV drivers only choose them when available and time allows. They’re slow, costly and take over 24 hours for full recharge – meaning most will opt for Level 2 outlets when possible.

One major limitation of Level 1 chargers is their lack of networked capabilities; drivers cannot locate them through an app and don’t benefit from as many capabilities as networked Level 2 chargers do.

Solutions exist for both of these issues: Level 2 electric vehicle chargers are increasingly common in residential and workplace settings and much faster than Level 1 chargers, typically operating off 208-volt to 240-volt AC outlets in North America and 230/400V AC outlets in Europe. Some even come equipped with advanced communications features such as access control, point of sale, load balancing and energy monitoring that make these units an excellent solution for multiunit dwellings and workplaces with multiple unit users where managing charging can be essential for efficient operations.

Level 2

Level 2 electric vehicle chargers provide charging at up to four times faster than any of the slower charging methods, delivering up to 25 miles per hour. At home, these are often installed in garages or near car parking spots in driveways. To operate at this level, a dedicated 240-volt outlet must be on an entirely separate circuit (neither that powers an electric clothes dryer nor kitchen range can use this outlet); licensed electricians may install one using existing home circuits but for optimal performance it would be wiser for one with its own dedicated breaker box circuit.

Level 1 charging involves connecting an EVSE, or electric vehicle supply equipment, into a standard 120-volt household wall outlet. An EVSE comes standard on every plug-in hybrid electric vehicle and can be used in many situations such as at work and home. A level 1 charger typically adds about 3.5 to 6.5 miles of range per hour of charging depending on battery size and time spent charging it up.

For electric vehicle (EV) drivers who want more daily range or wish to cut back on gasoline entirely, investing in a level 2 EV charger may be worthwhile. Though not necessary for all drivers, investing can reduce range anxiety while helping address logistical concerns as they transition towards an all-electric commute.

Level 2 chargers differ from Level 1 in that they use a 240-volt system that supplies higher current to the battery, usually operating up to 80 amps or approximately 6.0kW of power (this may differ depending on how your EV’s onboard charger works, so please refer to your owner’s manual for details). These charges provide enough power for most electric cars to recharge within four hours, but may not meet the charging needs of cars such as Tesla Model 3 which require over 100 miles worth of juice within an hour.

Like their Level 1 counterparts, level 2 chargers can also be connected to a network and managed via an app, providing greater convenience for drivers needing extra range. They also enable station owners to track usage reports to make more informed business decisions.

Level 3

Level 3 electric vehicle chargers are fast becoming the Speedy Gonzales of EV charging, making them easier than ever to find throughout town. Operating at either 480V or 1,000V, Level 3 chargers can quickly add miles to an EV battery in about the same amount of time it would take a gasoline car to fill up its tank – such as at highway rest stops, mall parking garages and restaurants/hotels/shopping centers etc. They look similar to regular wall outlets but provide up to 25KWs – adding 100-250 miles in 30 minutes!

Though long-term wear and tear on an EV battery charged at Level 3 rates is debatable, public stations make Level 3 charging highly accessible and convenient when driving around town.

Home installation of a Level 3 charger may not be the most economical choice; typically a typical installation costs several thousand dollars depending on factors like charger specifications, physical placement requirements and electrical upgrades as well as local rebate and incentive programs that could potentially offset expenses incurred through faster charging speeds.

Although there are various EV charging types out there, the three levels identified by Society of Automotive Engineers (SAE) remain the most popular ones. You can learn more by visiting our blog where we explain EV charging levels in greater depth. No matter which form of charging they opt for, every EV owner must ask themselves certain key questions to determine their ideal method. As part of your preparations, it is recommended that drivers understand how different charging options fit together to give drivers maximum flexibility in their daily lives and travel plans. Some EV owners prefer charging overnight at home or the office while others opt for fast-charging stations when making important trips.

Fast Chargers

Battery chargers are devices used to provide electricity to rechargeable electric vehicle (EV) batteries at high rates of charging. AC to DC converters convert AC power, allowing for rapid battery recharging times. There are various types of chargers designed specifically for specific vehicles or applications.

Level 1 chargers plug directly into standard 120 V outlets and can fully charge batteries within 32 hours, while 240V level 2 chargers take half as much time to do the same thing.

Power output of charging stations plays a pivotal role in how long it takes your new EV to charge, with higher kW ratings enabling faster charging of your car.

CCS and CHAdeMO are two open standards for fast charging: developed by seven car makers in 2014 with initial support up to 80 kW, respectively; while CHAdeMO Association released theirs in 2010 with 50kW support.

Both CHAdeMO and CCS provide multiple connections for different cars, but the Combined Charging System (CCS) remains the most efficient choice, thanks to its adaptable features that make it more compatible with various vehicles; additionally, its built-in DC to AC power conversion capabilities reduce external hardware requirements significantly.

It has a dedicated onboard charger to control and monitor power deliveries to the battery, assessing its condition and adjusting current accordingly. Furthermore, this charger monitors and protects by decreasing charging rate at critical temperatures.

EVgo, one of the country’s largest public fast charging networks, uses these technologies to offer its customers an exceptional fast charging experience. Their stations feature well-lit parking spots with canopies for shade, signage that clearly identifies each charging point, as well as other amenities such as snack machines and water fountains.

Workplaces are increasingly adopting electric vehicle charging stations as part of their sustainability initiatives or employee engagement strategies, providing much-needed convenience by not forcing workers to leave their vehicle during working hours and being back into a fully charged car as soon as the day has ended.
