Whether you’re considering buying an electric vehicle (EV) or you already have one, understanding the different types of EV chargers is important. With the right charger, you can get your EV up and running quickly and efficiently. Here’s a quick overview of the different types of EV chargers on the market.
What is the difference between AC EV chargers and DC EV chargers?
Electric vehicle (EV) charger technology is an important part of the EV industry and can be divided into two distinct categories. AC EV charger works by supplying alternating current (AC) power to the car, converting it into direct current (DC) power for the battery which then powers the electric motor. DC EV chargers, on the other hand, supply direct current (DC) directly to the electric motor and battery so that they can receive a charge without any conversion. Each of these types of chargers has its own unique benefits and drawbacks depending on which type of vehicle you have, but both play an essential role in ensuring that EVs are efficient and able to travel long distances.
Different classifications of EV charging in the US
EV owners have to take a few different things into consideration when it comes to electric vehicle charging. In Europe and the US, EV charging stations are classified differently. In the US, EV chargers are categorized according to the voltage level at the input of the charging station as Level 1, 2 or 3.
Level 1 in the US
Charging up your electric vehicle just got simpler! Level 1 charging uses a common household outlet, making it incredibly easy to charge and go. Although this is the slowest way of charging an EV – adding between 3-5 miles per hour, depending on the size of its battery – it’s ideal for Plug-in Hybrid Electric Vehicles (PHEVs) with smaller batteries. But if you drive long distances every day or own an all-electric Vehicle (BEV), then investing in faster Level 2 technology might be better suited for your needs.
Level 2 in the US
Want to make sure your EV is ready for every journey? Level 2 charging may be the answer—it’s the go-to choice among BEV owners, and it can charge up a nearly empty battery in as little time as overnight! This type of charger is what you’ll typically find at locations like homes, workplaces or public spaces. Depending on the power output and vehicle specs, level 2 chargers replenish 20-60 miles per hour – that’s 10x faster than traditional Level 1 chargers.
They offer an impressive amount of power for electric vehicles compared to level 1 chargers, typically providing up to 80 amps over a dedicated circuit. This gives users much faster charging times but comes with a catch – the charger requires a 100-amp 208-240V dedicated circuit and a heavy, expensive supply line from the breaker box. Of course, this extra expense is necessary to support the amperage increase and ensure safety during charging.
However, considering that customers usually save money in the long run by switching from gasoline-fueled cars to electric cars, investing in Level 2 chargers can be a great option for those looking for convenient and quick charging on the go.
Level 3 in the US
Level 3 charging is the fastest way to refuel your EV, allowing it to reach up to 5 miles in range per minute. This type of charger utilizes direct current (DC) as opposed to alternating current (AC), which requires a much higher voltage (480V) than Level 1 and 2 chargers. Unfortunately, these chargers are typically not found at home due to the high voltage required for them and their installation cost that easily runs into tens of thousands of dollars which is too costly.
Different classifications of EV charging in Europe
EV owners in Europe may have heard of the Mode 1/2/3/4 classification, which indicates different levels of EV charging capability. This classification is based on whether the EV is able to communicate with the EV chargers.
Mode 1 in Europe
Mode 1 charging refers to that electric vehicles are typically charged by directly connecting them to standard household sockets. However in several countries including Italy and Switzerland, this kind of direct connection is not legal due to its lack of safety measures – current and voltages must be kept under 16 A/250 V (single-phase) or 16A/480V (three-phase). Regulations also apply across a number of other European nations such as Denmark, Norway, France, Germany, England and Israel.
Mode 2 in Europe
Mode 2 charging provides an extra layer of safety by requiring the use of a Control box, typically installed on portable chargers for electric vehicles. Mode 2 allows both domestic and industrial sockets to be used, though restrictions vary in different countries around the world such as Italy, the United States, Canada, Switzerland, Denmark France and Norway. Currents up to 32 A with voltages between 250 – 480 V are allowable depending on whether single or three-phase connections are made respectively.
Mode 3 in Europe
Mode 3 charging offers an efficient and convenient way to keep your car powered up! This type of charger is integrated directly into dedicated power supplies that are permanently connected to the electrical grid. In Italy, this mode is the only one allowed for public spaces so you can easily stay charged when out and about. Mode 3 chargers provide a powerful charge with no upper voltage limits – giving single-phase output at 32 A/250 V or three-phase output at 32A/480V – keeping you on the go all day long!
Mode 4 in Europe
Mode 4 is the only way to charge your electric vehicle with direct current. This charging option requires an external converter and a larger-than-usual station, as compared with a conventional charger. The clever converter transforms alternating current into DC before it goes through then cables straight to your car!
Mode 4 charging provides complete flexibility for electric vehicle owners, as it supports both Japanese and European standards (CHAdeMO & CCS Combo) with no upper limit on current or voltage. That means your EV can get juiced up at a higher rate of speed – so you’ll be back out in the world before you know it!
What is the difference between private EV chargers and commercial EV chargers?
Private EV chargers are typically installed for residential use and can be used by the owner of the home. Private EV chargers are usually Level 2 chargers, which provide a faster charging rate than Level 1 chargers. On the other hand, commercial EV chargers are typically installed in public locations and are available for use by anyone who needs to charge their EV. They also usually come with additional features such as payment systems or access control measures that may not be available on private EV chargers. Additionally, they are often built to withstand more wear and tear due to being used by multiple users.
Conclusion
Now that you know the different types of EV chargers and their modes, you’re equipped to start charging your car at home or on the go. Be sure to keep this information in mind when purchasing an electric vehicle or any accessories for your current EV. And be safe out there—happy driving!
