What You'll Learn
Charging speeds and power loads
The charging speed and power load of an electric vehicle (EV) depend on the type of charger and the vehicle's battery capacity. Different types of chargers include Level 1, Level 2, and Level 3 or DC Fast Chargers. Level 1 chargers are the most basic and slowest option, providing a ''trickle charge'' through a standard 110/120-volt plug found in North American homes. They can take up to 50 hours to fully charge an EV, adding only 3 to 5 miles of range per hour. Level 1 chargers are typically included with the purchase of an EV.
Level 2 chargers run at 240 volts and can be easily installed by an electrician. They offer a faster charging option, adding approximately 25 miles of range per hour. Level 2 chargers are common in homes, workplaces, and public settings, and they can charge an EV from empty in 4 to 10 hours, depending on the model. Level 2 charging is recommended for daily use and can be scheduled during off-peak hours to save on electricity costs.
Level 3 chargers, also known as DC Fast Chargers, require a robust DC stream of electricity exceeding 480 volts and 100 amps. These chargers can fully charge an EV in as little as 20 to 30 minutes, making them ideal for commercial or retail setups where drivers need rapid battery replenishment. However, Level 3 chargers are not commonly found in homes.
In addition to the charger levels, there are different plug types and connectors used for EVs. In North America, the standard plug is the Type 1 J1772, while in Europe, Tesla cars use CCS2 charging. The Combined Charging System (CCS) connector is common in North American and European vehicles, while the CHArge de Move (CHAdeMO) connector is typically found in Japanese-made vehicles. Tesla vehicles have their own unique connector that works at all charging speeds, but they may require adapters for non-Tesla stations.
The variety of plug types and charging standards can be a challenge for EV drivers, especially when travelling across different territories. However, the push for open protocols and standardized charging infrastructure is gaining momentum, aiming to provide a more seamless and consistent experience for EV users.

Charging locations
Charging an electric vehicle (EV) requires more thought than filling up a car with an internal combustion engine, where the only distinction is between gas and diesel pumps. The electric vehicle sector is still evolving, and while standards are being developed, there are currently different charging standards and connector types to contend with. This can depend on the territory, power source, and vehicle type.
There are three main charging locations for electric vehicles: home, public, and workplace. Home charging is the most popular option, with over 80% of charging sessions taking place at home. This is because it is the most convenient and cost-effective option for most EV owners. The standard charger that comes with an EV plugs into a 110/120-volt outlet, but it charges slowly, taking about 20 hours for a full charge. Level 1 chargers are also available, which use a standard 110/120-volt plug, adding 3 to 5 miles of range per hour.
Public charging stations are another option, and these can be found using online tools and maps. In the United States, public charging networks operate different stations, and charging standards vary across the country. The Joint Office of Energy and Transportation provides a map of electric vehicle charging stations, showing charging levels, access types, and other key data points. PlugShare also offers a service to find electric vehicle charging locations near you.
Workplace charging can be a great way to increase the daily electric range of an EV, especially for plug-in hybrids, and some employers cover the costs of charging. Governments in some regions offer incentives to employers to install EV charging stations, and employees can help by informing their employers about these programs.

Charging terminology
Electric vehicle (EV) plugs are not yet standardised across the world. The terminology around EV charging can be confusing, with terms often used interchangeably. Here is a breakdown of some key charging terms:
Charging Levels: There are three main charging levels for EVs, each with a different voltage and charging speed. Level 1 chargers are the most basic, using a standard 110/120 volt plug found in North American homes. They are slow, adding only 3 to 5 miles of range per hour, but are widely available. Level 2 chargers run at 240 volts and can be easily installed by an electrician. They are significantly faster, adding approximately 25 miles of range per hour. Level 3 chargers, also known as DC Fast Chargers, require a high-power DC stream of electricity and can fully charge a battery in 20 to 30 minutes.
Plug Types: The Type 1 plug is used for Level 1 and 2 charging in North America and Asia, and it is a 5-pin plug that can draw power up to 19.2 kW. In Europe, the standard for Level 1 and 2 charging is a 7-pin plug, which allows for higher power draw and features an automatic locking mechanism. For fast Level 3 charging, a CCS1 plug is required.
Connectors: The J1772 is the standard Level 2 connector found on most vehicles and is capable of charging at both Level 1 and Level 2 speeds. CHAdeMO is an early form of DC quick charging developed by Japanese carmakers, and it is compatible with several brands of electric cars, including Nissan, Honda, and Tesla (with an adapter). Tesla vehicles have their own connector, which is only compatible with Tesla-brand cars, but a CCS adapter is available to allow charging at any fast-charging station.
Charging Locations: Home charging is the most common way to charge EVs, with over 80% of charging sessions occurring at home. Workplace charging can also be a convenient option and can nearly double an EV's daily electric range. Public charging stations are also available and can be found using apps such as the EV Connect Driver App, which helps drivers find compatible connectors.
As the EV sector continues to evolve, standardisation of plugs and charging infrastructure is still a work in progress. Understanding the various charging levels, plug types, and connectors is essential for EV owners to maximise their convenience and efficiency when charging their vehicles.

Charging standards
Electric vehicle (EV) charging standards refer to the different types of plugs, connectors, and adapters used to charge electric vehicles. While the ideal scenario would be for all electric vehicles to use a universal plug, the reality is that various factors influence the type of plug required, such as territory, power source (slow vs. fast charging), and vehicle type. Here is a detailed breakdown of the different charging standards:
Level 1 Charging:
Level 1 charging is the most basic and slowest form of charging. It typically uses a standard 110/120-volt plug found in North American homes. While it is slow, Level 1 charging is convenient for at-home charging, as it can be plugged into a standard electrical outlet. However, it can take up to 20 hours to fully charge a vehicle, adding only 3 to 5 miles of range per hour.
Level 2 Charging:
Level 2 chargers operate at 240 volts and can be installed by an electrician for at-home charging. They charge vehicles significantly faster than Level 1 chargers, adding approximately 25 miles of range per hour. Level 2 charging stations are the most common type found in public spaces and private businesses. In North America, all Level 2 chargers use the SAE J1772 connector, also known as the Type 1 connector.
Level 3 Charging:
Level 3, also known as DC Fast Charging, is the fastest form of charging. It requires a robust DC power stream exceeding 480 volts and 100 amps. Level 3 charging can fully charge a battery in as little as 20 to 30 minutes, making it ideal for commercial or retail setups. However, it requires a compatible connector, such as the CHAdeMO or SAE Combo CCS connector.
The type of plug used also varies by region. In North America, the standard plug is the Type 1 J1772, while in Europe, Tesla cars use CCS2 charging. Each continent and sometimes each country has its own standards, requiring adapters or transformers for international travellers with electric vehicles.
Vehicle-Specific Standards:
Some vehicles, such as Teslas, have their own proprietary charging standards and networks of fast-charging stations. While Teslas come with adapters to use other charging networks, non-Tesla vehicles typically cannot use Tesla superchargers. However, Tesla is expected to support non-Tesla vehicles with its external charger in the future.
Charging Connectors:
There are two main types of EV charging connectors: Type 1 and Type 2. Type 1, also known as J1772 or SAE J1772, is used for Level 1 and 2 charging and is the standard in North America and Asia. Type 2, or Mennekes, is primarily used in Europe and features seven pins, automatic locking, and support for single-phase and three-phase AC charging.
In summary, while there is a push for standardization in the EV industry, the current landscape involves various charging standards that EV owners must navigate to efficiently charge their vehicles. Understanding the different charging levels, connectors, and regional variations is crucial for maximizing the convenience and efficiency of owning an electric vehicle.

Connector types
Electric vehicle (EV) connector types vary by region, power source, and vehicle type. There are two primary electric vehicle charging methods: AC (alternating current) charging and DC (direct current) fast charging. AC charging is the most common charging type and includes Level 1 and Level 2 charging in North America. Level 1 charging involves plugging your EV into a standard outlet at home with the cable that comes with your EV. This typically runs at 110/120V, adding 3 to 5 miles of range per hour, and can take about 20 hours to fully charge an EV. Level 2 charging requires a dedicated charger and can add 25 to 40 miles of range per hour. Level 2 chargers run at 240V and can be installed by an electrician.
The standard Level 2 charging connector in North America is the SAE J1772 connector, also known as a J Plug or Type 1 connector. It features five pins and can charge up to 80 amps using 240V input, providing a maximum power output of 19.2 kW. The J1772 connector supports single-phase AC charging for Level 1 and Level 2 EV chargers. The drawback of the Type 1 connector is that it only allows single-phase use and does not have an automatic locking mechanism like the Type 2 connector used in Europe. All vehicles can use the Type 1 plug for Level 1 and 2 charging.
In Europe, the Type 2 connector is the standard for home charging. The Type 2 connector has seven pins, can carry three-phase power, and has an in-built locking mechanism. The CCS Type 1 (Combined Charging System) or CCS Combo 1 combines the J1772 Type 1 plug with two high-speed DC fast-charging pins. It is the DC fast-charging standard for North America, delivering up to 500 amps and 1000 volts DC, with a maximum power output of 360 kW.
For DC rapid charging, there are three types of car-side connectors: CHAdeMO, CCS, and NACS (Tesla). Most DC rapid charging stations have cables with both CHAdeMO and CCS connectors. CHAdeMO is an early form of DC quick charging established by a consortium of Japanese carmakers. CCS Combo 1 utilizes the same communication protocol as the SAE J1772 Type 1 connector, enabling vehicle manufacturers to have one AC and DC charging port. NACS, developed by Tesla, combines both AC and DC charging compatibility in one connector.
