Are Electric Car Chargers Universal?
While all electric vehicles use the same standard plug for Level 1 and Level 2 charging, the standard for DC charging may vary by Connector Supplier and region
Different types of plugs and chargers based on charging type
Electric vehicle charging can be divided into three different levels. These levels represent the power output, or charging speed, that can be used to charge an electric vehicle. Each level has a designated connector type, designed for low or high power use, and is used to manage AC or DC charging. The different charging levels for electric vehicles reflect the speed and voltage at which you can charge your vehicle. In summary, the standard plugs for Level 1 and Level 2 charging are the same and both will have adapters that fit, but DC fast charging requires a separate plug depending on the brand.
Level 1 charging (120 volts AC)
Level 1 chargers use a 120 volt AC plug that simply plugs into a standard electrical outlet. This can be done using a Level 1 EVSE cable that has a standard 3-phase household plug for the outlet and a standard J1722 connector for the vehicle on one end. When connected to a 120V AC plug, charging rates range from 1.4kW to 3kW and may take 8 to 12 hours, depending on battery capacity and condition.

Level 2 charging (240V AC)
Level 2 charging is primarily a public charge. Unless you have a Level 2 charging facility at home, most Level 2 chargers can be found in residential areas, public parking lots, and workplace and commercial environments. Level 2 chargers need to be installed and provide charging through a 240V AC plug. Charging typically takes between 1 and 11 hours (depending on battery capacity), with rates ranging from 7kW to 22kW using a Type 2 connector. e.g., a KIA e-Niro with a 64kW battery would have an estimated charging time of 9 hours with a 7.2kW in-vehicle Type 2 charger.
DC Fast Charging (Level 3 Charging)
Level 3 charging is the fastest way to charge an electric vehicle. While it may not be as common as Level 2 chargers, Level 3 chargers can be found in any major population center. Unlike Level 2 charging, some EVs may not be compatible with Level 3 charging. Level 3 chargers also need to be installed and provide charging through a 480V AC or DC plug. Charging times can take 20 minutes to an hour at rates from 43kW to 100+kW using CHAdeMO or CCS connectors. level 2 and level 3 chargers both have connectors that connect to charging stations.
Like every device that needs to be charged, your car battery will become less efficient each time you charge it. If properly maintained, a car battery can last over five years! However, if you use your car daily under average conditions, it is best to replace it after three years. Beyond that, most car batteries will not be as reliable and can lead to many safety issues.
Types of charging cables for charging electric cars
Mode 2 charging cables
Mode 2 charging cables are generally used for home outlet connections and are available from manufacturers and in various versions depending on the region. Called ICCB In-Cable Control Box, a box is installed that allows communication between the connector plug and the vehicle plug.
Mode 3 Charging Cable
Mode 3 charging cables also vary by region, but connect the charging station directly to your electric vehicle. Charging stations are typically equipped with a mode 2 outlet to allow the vehicle to be charged using both a mode 1 and a mode 2 plug. Depending on the region and manufacturer, a mode 3 charging cable from type 2 to type 2 or a mode 3 charging cable from type 2 to type 1 is required.
