Charger Types and Speeds
EVs can be charged using electric vehicle service equipment (EVSE) operating at different charging speeds.
Level 1 equipment provides charging through a common residential 120-volt (120V) AC outlet. Level 1 chargers can take 40-50 hours to charge a BEV to 80 percent from empty and 5-6 hours for a PHEV.
Level 2 equipment offers higher-rate AC charging through 240V (in residential applications) or 208V (in commercial applications) electrical service, and is common for home, workplace, and public charging. Level 2 chargers can charge a BEV to 80 percent from empty in 4-10 hours and a PHEV in 1-2 hours.
Direct Current Fast Charging (DCFC)
Direct current fast charging (DCFC) equipment offers Rapid charging along heavy-traffic corridors at installed stations. DCFC equipment can charge a BEV to 80 percent in just 20 minutes to 1 hour. Most PHEVs currently on the market do not work with fast chargers.
Level 2 and DCFC equipment has been deployed at various public locations including, for example, at grocery stores, theaters, or coffee shops. When selecting a charger type, consider its voltages, resulting charging and vehicle dwell times, and estimated up-front and ongoing costs.
The figure below shows typical Level 2 and DCFC charging stations 1.
EV Charging Minimum Standards Rule
FHWA, with support from the Joint Office of Energy Transportation, unveiled new national standards for federally funded EV chargers in February 2023. These new standards aim to ensure that charging is a predictable and reliable experience for EV drivers. This includes ensuring that drivers can easily find a charger, do not need multiple apps and/or accounts to charge, chargers work when drivers need them to, and are designed to be compatible in the future with forward-looking charging capabilities.
The rule establishes minimum technical standards for charging stations, including required number of charging ports, connector types, power level, availability, payment methods, uptime/reliability, EV charger infrastructure network connectivity, and interoperability, among other standards and requirements.
Overview of EV Chargers
The below table summarizes the typical power output, charging time, and locations for PHEVs and BEVs for the different charger types. For more information on the power requirements of different chargers, see the Utility Planning section of the toolkit.
1 Note that charging speed is affected by many factors, including the charger manufacturer, condition, and age; air temperature; vehicle battery capacity; and vehicle age and condition.
2 Different vehicles have different charge ports. For DCFC, the Combined Charging System (CCS) connector is based on an open international standard and is common on vehicles manufactured in North America and Europe; the CHArge de Move (CHAdeMO) connector is most common for Japanese manufactured vehicles. Tesla vehicles have a unique connector that works for all charging speeds, including at Tesla’s “Supercharger” DCFC stations, while non-Tesla vehicles require adapters at these stations.
3 AC = alternating current; DC = direct current.
4 Assuming an 8-kWh battery; most plug-in hybrids do not work with fast chargers.
6 To 80 percent charge. Charging speed slows as the battery gets closer to full to prevent damage to the battery. Therefore, it is more cost- and time-efficient for EV drivers to use direct current (DC) fast charging until the battery reaches 80 percent, and then continue on their trip. It can take about as long to charge the last 10 percent of an EV battery as the first 90 percent.
KW EV Charger Costs
Installing your own EV charger can be a cost-effective and convenient way of charging your EV overnight or during working hours. Rapid or super-fast chargers with a 50kW power supply can charge an EV battery to 80% in roughly 20 minutes, costing from £1,500 and upward to fit.
Most home EVs tend to be either 7kW or 22kW, and a 50kW EV charging dock is only usually suitable for commercial use – you’ll find these chargers at service stations and some larger car parks.
There is a caveat that frequent recharging with a Rapid EV charger can deteriorate your battery life span, so it is better to use them occasionally or for small top-ups rather than as the primary source of charging.

Comparing Costs of Different KW EV Chargers
When you receive quotes to install your home EV charger, the price should include supply and installation costs, which means you are paying for the charging unit and the labour required to fit the station ready for use.
Rapid EV chargers cost more than slower, more economical models. However, the labour costs will normally be around 20% of the charger cost – the more complex the electrical components, the longer it will take to fit.
There are also various types of EV chargers, each of which is suitable for a different property type and intended use.
|EV Charger Size||Average Cost||Pros||Cons|
|Slow 3kW charger||£300. £800||Slow charging creates less heat and requires less power output.||Charging can take up to 14 hours to fully replenish the battery.|
|Fast 7kW charger||£400. £900||Charges a battery in around four to six hours and is normally suitable for residential installation.||Uses a higher amount of power, so it can be more expensive in terms of electricity bills.|
|Rapid 22 – 50kW chargers||£1,020. £1,520||Ideal for fast charges in under 30 minutes.||Designed for commercial buildings and can impact the longevity of an EV battery.|

Home EV installers usually recommend a smaller 7kW or 22kW charger as an appropriate charging unit for a private property, although you can certainly install a Rapid charger at a workplace or shared charging facility to allow super-fast charging.
Additional Costs Associated With a 50KW Charger Installation
It costs more to install a fast or Rapid charger because an EV charging unit classed as a slow level one charger can work with any standard power supply. They use 120-volt electricity, so connecting to your home electrical system is simple.
Fast chargers (level two) need a bigger 240-volt power supply, which is why they are primarily used at business premises rather than residential accommodation.
If your system is suitable for this level of power output, an electrician will need to carry out additional work to fit circuit breakers, replace your home consumer unit or install a new isolated circuit solely to power the EV charger.
Cables are linked to the fuse box but are only used to run the charger, insulating the rest of your electrical cabling from potential damage.
Factors in the Cost of Fitting a 50KW Charger
The charging output is one of the most significant cost factors when deciding which EV charger to install. Costs of buying the unit itself can vary considerably from a small 3kW home charger, which is multiple times lower than a Rapid 50kW charger.
Your installation contractor will also normally ask to schedule a site visit to help them ascertain other measurements and elements of the installation work that will affect the price:
- Longer charging cables add around £10 per metre to your EV charger installation quote, as most suppliers provide standard-length cables.
- Fitting a charging port inside a garage may incur additional costs in labour and materials to fit the charger on an internal wall and make good the finish.
- Wireless connectivity, which allows you to manage your EV charger through a mobile app, can add approximately £40 to £150 to the cost of the charging unit.
- Replacing your consumer unit or adding extra circuit breakers to accommodate a Rapid charger will increase your quote by around £350.
Another potential cost element is an earthing system, which is necessary when there is a risk that faulty electrical circuits will cause damage to your system and pose a possible safety hazard.
On average, a set of grounding rods to protect your system and property can add a further cost of £300.
How to Choose the Right EV Charger Power Outage
As we have mentioned, a super Rapid 50kW charger is more commonly found at service stations and is not generally available for installation on private residential premises.
It may be useful to compare the average charging time and the power outage required to support the size of EV charger you would like.
- 7kW chargers are used for on-street and off-road parking and take around six to ten hours to charge an EV.
- 22kW chargers are also found at some properties, although they are considered fast chargers – they are more often installed at public car parks, retail parks or hospitality venues such as hotels, providing a charge in two to five hours.
- EV chargers of 25kW or above are normally installed in retail stores and charge an EV in around one hour, depending on the size of the battery.
- Super-Rapid 50kW chargers can provide a full charge in 30 minutes and are typically only available at service stations or garage forecourts.
While a 50kW charger may be one of the more expensive options, it could be perfect for an office or where you have electric company cars that need a speedy charging option before personnel head out for the day.
The power outage of your EV charger will also depend on which car model you have or expect to buy. Slow level one chargers are designed for smaller vehicles such as a Toyota Prius, Audi A3 e-Tron or a Nissan Leaf.
Type two chargers usually need a conversion cable to make the charging station compatible with other vehicles and are better for larger cars such as BMW, Tesla, Porsche, Range Rover, or Hyundai. You can check the vehicle specification for more information about charging options and compatibility.
Time Required to Install a 50KW Charger
Most new EV chargers take about two or three hours to install, although some elements might mean the work takes longer.
For example, if you want a wireless EV charging dock where the contractor needs to fit a charging plate into the floor, this work will be in addition to the standard installation time.
Complex installations with additional aesthetic repairs or where you need to have new electrical components fitted will also require longer.
Digging trenches for cabling can add around £30 per metre. Still, they could be more expensive if your tradesperson needs to break through concrete – this may mean hiring another contractor to complete the groundwork before an electrician can install your EV charger.
Properties with a solar panel system can use green energy to power their EV charger, but this can also be more involved. If there is already a solar energy storage battery, the EV charging dock can be connected to this, although you may need a new inverter and a specialist solar charger.
The benefit is that once your EV charging unit has been fitted, it will be relatively cost-free to run, provided you have sufficient power to charge your EV without reverting to the mains electricity grid.
Charging with Electrify America
Our Direct Current (DC) chargers offer the fastest charging speeds (Ultra-Fast 150 kW and Hyper-Fast 350 kW) —letting you charge in as little as 30 minutes! Here’s what to expect when you charge with the largest DC fast public charging network in the United States. learn the basics of electric vehicle charging
Tip: Not all EVs can charge at a connector’s maximum power level. For example, a Hyper-Fast label means the charger offers up to 350 kW for a CCS-compatible EV. If your car is not capable of a 350 kW maximum charge, the charger automatically supplies the highest power level your vehicle can handle. Check your vehicle’s manufacturer manual to learn your car’s capacity.
At Electrify America stations, you may notice the word “Balanced” on a charger’s labels or screen. Balanced chargers are typically located side-by-side and share a power cabinet. When a charger is Balanced, it can supply Ultra-Fast speeds up to 150 kW for vehicles capable of accepting this much power and can provide Hyper-Fast speeds up to 350 kW to capable vehicles when the adjacent charger is unused.
Balanced chargers are labeled with the tag below:

EV Charger Types
EV chargers are classified into three categories: Level 1, Level 2 and direct current (DC) fast chargers.
EV chargers are classified into three categories: Level 1, Level 2 and direct current (DC) fast chargers.
Important differences include:
- Input voltage. This is how much power a charger requires to operate and is expressed in volts.
- Power output. This is how much power a charger can generate and is expressed in kilowatts (kW).
- Charging speed. This is the number of miles added to the EV’s battery per hour of charging and depends on the charger’s power output.
- Equipment and installation cost. While basic EV chargers are inexpensive and can be plugged into a standard outlet, others have higher upfront equipment and must be installed professionally by an electric vehicle service provider (EVSP).
- EV power intake. Depending on your EV, the power output pulled from a charger (in kW) may be limited by how much the EV’s battery can withstand. Check your vehicle’s specifications to know which charging level your vehicle can use.
Numerous manufacturers produce EV chargers, with a variety of products, price points, applications and functionality. Because of these differences, it is important to choose an EV charger that fits your intended use and budget.
Direct Current Fast Charging
How fast is DC fast charging?
Depending on the EV, DC fast chargers can currently produce a 10-80% charge for a 300-mile range battery in approximately 20 minutes (~540 miles of electric drive per hour of charging).
What is the input voltage for a DC fast charger?
Currently available DC fast chargers require inputs of at least 480 volts and 100 amps, but newer chargers are capable of up to 1000 volt and 500 amps (up to 360 kW).
How much do DC fast chargers cost?
A CALeVIP Cost Data analysis found that the unit cost per charger for rebate recipients ranged from a minimum of 18,000 to a maximum of 72,500. The mean and median unit cost per charger was 29,135 and 23,000, respectively.
In addition to higher equipment costs, DC fast charger installations require a commercial electrician from the initial planning phase due to the electrical load and wiring requirements.
Is a DC fast charger the right EV charger for me?
DC fast chargers are the highest-powered EV chargers on the market. They often are used as range extenders along major travel corridors for long-distance trips and in urban environments to support drivers without home charging or very high mileage drivers. At current charging speeds, they are ideal for places where a person would spend 30 minutes to an hour, such as restaurants, recreational areas and shopping centers.
It is important to note that not every EV model is capable of DC fast charging, and therefore, they cannot be used by every EV driver. Further, DC fast chargers have multiple standards for connectors, whereas there is only one common standard for Level 1 and 2 charging (SAE J1772). DC fast chargers have three types of connectors: CHAdeMO, CCS and Tesla, though CCS is increasingly becoming the industry standard.
Level 2 Chargers
How fast is Level 2 charging?
A Level 2 charger can currently produce a full charge for a 300-mile range battery in about 6-8 hours and is perfect for destination and overnight charging.
What is the input voltage of a Level 2 charger?
Level 2 chargers typically require 220V or 240V service.
What is the power output of a Level 2 charger?
Level 2 chargers are available with a variety of power outputs from 3 kW to 19 kW, which can sometimes be adjusted.
How much do Level 2 chargers cost?
CALeVIP Cost Data show that rebate recipients reported average L2 equipment costs ranging from 685 to 6,626 per connector. The mean and median were 2,976 and 2,884 per connector, respectively.
Is a Level 2 charger the right EV charger for me?
Level 2 chargers are typical solutions for residential and commercial/workplace settings. Most offer higher power output than Level 1 chargers and have additional functionality.
Non-networked vs. networked chargers
In general, Level 2 chargers are distinguished between non-networked chargers and networked chargers.
Networked chargers have advanced capabilities, such as charge scheduling, load management and demand response. They are more common in commercial/workplace settings where payments are required or at multiunit dwellings (MUDs) where the property’s electricity bill is shared by multiple residents.
They may be designed for indoor or outdoor use (e.g., NEMA 3R, NEMA 6P, NEMA 4x rated).
Some models of networked chargers also can limit charging to certain hours, which allows the operator to maximize a time-of-use (TOU) electricity rate structure and only allow charging when electricity is the cheapest (usually sometime between 9 p.m. and 6 a.m.). This type of control also increases the likelihood of participating in utility demand response programs.
Some of the enhanced features of a networked Level 2 charger include remote access/control via Wi-Fi or cellular connection, access control/ability to accept multiple forms of payment, load balancing across multiple chargers and more. Additionally, California will soon begin allowing the use of submeters already embedded within networked chargers to bill electricity use. For more information on submetering, visit the California Public Utilities Commission (CPUC) website.
Non-networked Level 2 chargers are used both in single-family residences and MUDs. They may be designed for indoor or outdoor use (e.g., NEMA 3R, NEMA 6P, NEMA 4x rated). Non-networked Level 2 chargers are useful for installations at MUDs or commercial sites that are powered by the residents’ or tenants’ subpanels.
In this case, any electricity used by the chargers will be charged to the individual’s electricity bill, thus eliminating the need to separately meter the chargers. Further, when electrical capacity is available, non-networked Level 2 chargers are useful for site hosts that need higher power than Level 1 charging but do not have a large budget.
