Are electric car chargers universal? | iFlowPower

“Though all EVs use the same standard plugs for Level 1 and Level 2 charging, standards for the DC charging may vary among manufacturers and regions.”

Different types of plugs and chargers based on types of charging 

EV charging can be categorized into three different levels. These levels represent the power outputs, therefore charging speed, accessible to charge an electric car. Each level has designated connector types that are designed for either low or high power use, and for managing AC or DC charging. Different levels of charging for your electric car reflect the speed and voltage at which you charge your vehicle. In short, it is the same standard plugs for Level 1 and Level 2 charging and will have applicable adapters, but individual plugs are needed for DC fast charging based on different brands.

Types of electric car plug

1. SAE J1772 (Type 1):

   - Charging Method: Used for alternating current (AC) charging.

   - Applicable Regions: Mainly used in North America.

   - Features: The SAE J1772 connector is a plug with a notch, known for its strong compatibility, suitable for most electric vehicles.

   - Charging Speed: Typically used for home and public AC charging stations, offering slower charging speeds suitable for daily charging needs.

Level 1 Charging (120-volt AC)

Level 1 chargers use a 120-volt AC plug and can be simply plugged into a standard electrical outlet. It can be done with a Level 1 EVSE cable which has a  standard three-prong household plug on one end for the outlet and a standard J1722 connector for the vehicle. When hooked up to a 120V AC plug, charging rates cover between 1.4kW to 3kW and may take up anywhere from 8 to 12 hours depending on battery capacity and state. 

Level 2 Charging (240-volt AC)

Level 2 charging refers to a charging method for electric vehicles (EVs) that uses a higher voltage than standard household outlets. It typically involves a 240-volt power source and requires the installation of a special charging station or wall-mounted charger. 

Level 2 charging is considerably faster and can provide a higher charging rate. It is commonly used at home, workplaces, and public charging stations to recharge EVs. Level 2 chargers are compatible with most EV models and can fully charge a vehicle in a matter of hours, depending on the battery capacity.

Level 2 charging offers convenience and flexibility for EV owners, as it provides faster charging times and enables longer driving ranges. However, it is important to note that Level 2 charging infrastructure may not be as widely available as Level 1 charging, particularly in certain regions or locations.

DC Fast Charging (Level 3 Charging)

Level 3 charging is the fastest way to charge an electric vehicle. Though may not be common as Level 2 chargers, Level 3 chargers can also be found in any major densely populated locations. Unlike Level 2 charging, some EVs may not be compatible with Level 3 charging. Level 3 chargers also require installation and offer charging through 480V AC or DC plugs. Charging time can take up from 20 minutes to 1 hour with a charging rate of 43kW to 100+kW with a CHAdeMO or CCS connector. Both Level 2 and 3 chargers have connectors tethered onto the charging stations.

As it is with every device that needs charging, your car batteries will decrease in efficiency with every charge. With proper care, car batteries can last for more than five years! However, if you use your car daily under average conditions, it would be good to replace it after three years. Beyond this point, most car batteries won’t be as reliable and could lead to a number of safety issues.

2. Type 2 (Mennekes):

   - Charging Method: Used for alternating current (AC) charging.

   - Applicable Regions: Mainly used in Europe.

   - Features: The Type 2 connector is a cylindrical plug, commonly seen, and capable of supporting higher charging power.

   - Charging Speed: Designed for high-power charging, providing faster AC charging speeds.

3. CHAdeMO:

   - Charging Method: Used for direct current (DC) fast charging.

   - Applicable Regions: Mainly adopted by Japanese and some Asian car manufacturers.

   - Features: The CHAdeMO connector is a relatively large plug, typically used to support high-power fast charging.

   - Charging Speed: Suitable for fast charging stations, delivering high-speed charging suitable for long-distance travel and emergency charging needs.

4. Combined Charging System (CCS):

   - Charging Method: Used for both alternating current (AC) and direct current (DC) fast charging.

   - Applicable Regions: Mainly used in North America and Europe.

   - Features: The CCS connector integrates the Type 2 connector (for AC charging) and two additional conductive pins (for DC fast charging), allowing vehicles to charge from the same plug for both AC and DC.

   - Charging Speed: Capable of providing faster AC and DC charging speeds, catering to different charging needs.

5. GB/T (National Standard):

   - Charging Method: Used for both alternating current (AC) and direct current (DC) charging.

   - Applicable Regions: Mainly used in mainland China.

   - Features: The GB/T connector is a charging standard developed by the Chinese National Standards Committee, widely compatible with different types of electric vehicles and charging equipment.

   - Charging Speed: Offers flexible charging options suitable for various charging scenarios.

6. Tesla:

   - Charging Method: Mainly used for Tesla brand electric vehicles.

   - Applicable Regions: Tesla charging networks globally.

   - Features: Tesla adopts unique charging connectors and standards, compatible only with Tesla brand vehicles, not usable for other electric vehicle brands.

   - Charging Speed: Tesla charging stations provide high-power charging, enabling faster charging speeds suitable for Tesla vehicle's rapid charging needs.

These standards cover the charging requirements of different regions and vehicle models, providing multiple options for electric vehicle users. However, due to the diversity of charging standards, some charging facilities may need to be equipped with multiple types of charging connectors to meet the charging needs of different brands and models of electric vehicles.
