Electric Vehicle Charging: Everything You Need 

Electric vehicles (EVs) are becoming more popular and accessible, as they offer many benefits such as lower emissions, lower maintenance costs, and higher efficiency. However, EVs also require a different way of refueling than conventional vehicles, which can be confusing and daunting for beginners. That is why we have compiled a guide that covers everything you need to know about electric vehicle charging, from how it works, to what are the different levels and types of charging, to how to find and use charging stations.

How Are Electric Vehicles Charged?

Electric vehicles are charged by plugging them into an external power source, such as a wall outlet, a dedicated charging station, or a public charging network. The power source provides electricity to the EV's battery, which stores the energy and powers the electric motor that drives the wheels. The charging process can vary depending on the type and capacity of the battery, the power level and plug type of the charging station, and the state of charge and temperature of the battery. Generally, the higher the power level and the lower the state of charge, the faster the charging time. However, the charging speed also decreases as the battery gets closer to full, to prevent overcharging and damage.

Do you know the Power Level of Charging?

The power level of charging refers to the amount of electricity that the charging station can deliver to the EV's battery. The power level is measured in kilowatts (kW) and determines how fast the EV can be charged. There are three main levels of charging: Level 1, Level 2, and Level 3.

Charging Level One: L1

Level 1 charging is the simplest and slowest way of charging an EV. It uses a standard 120-volt (V) AC wall outlet and a cord that connects the EV to the outlet. Level 1 charging can provide up to 1.9 kW of power, and can charge an EV at a rate of about 2 to 5 miles of range per hour. Level 1 charging is suitable for overnight or long-term charging or EVs with small batteries and low range. However, it is not practical for fast or frequent charging, or EVs with large batteries and high range.

Charging Level Two: L2

Level 2 charging is the most common and convenient way of charging an EV. It uses a 240-volt (V) AC power source and a cord that connects the EV to a dedicated charging station or a public charging network. Level 2 charging can provide up to 19.2 kW of power, and can charge an EV at a rate of about 10 to 60 miles of range per hour. Level 2 charging is suitable for daily or regular charging or EVs with medium to large batteries and moderate to high range. However, it is still not fast enough for long-distance travel or emergency charging.

Charging Level 3 DCFC: L3

Level 3 charging, also known as DC fast charging (DCFC), is the fastest and most advanced way of charging an EV. It uses a 480-volt (V) DC power source and a cord that connects the EV to a high-powered charging station or a public charging network. Level 3 charging can provide up to 350 kW of power, and can charge an EV at a rate of about 60 to 300 miles of range per hour. Level 3 charging is suitable for long-distance travel or emergency charging or for EVs with large batteries and high range. However, it is also the most expensive and least available way of charging, and not all EVs are compatible with it.

Types of Charging Plugs :

The type of charging plug refers to the shape and size of the connector that attaches the EV to the charging station. The type of charging plug determines the compatibility and interoperability of the EV and the charging station and affects the power level and speed of charging. There are three main types of charging plugs: SAE J1772, CCS, and CHAdeMO.

First, the SAE J1772 :

The SAE J1772 plug, also known as the Type 1 plug, is the most widely used and standardized plug for EV charging. It is compatible with both Level 1 and Level 2 charging and can deliver up to 19.2 kW of power. It has a round shape and five pins and can be plugged into any EV or charging station that supports the SAE J1772 standard. It is mainly used in North America and Japan, and by most EV manufacturers, such as Tesla, Chevrolet, Ford, Nissan, and Toyota.

Second, the CCS :

The CCS plug, also known as the Combined Charging System or the Type 2 plug, is a newer and more advanced plug for EV charging. It is compatible with both Level 2 and Level 3 charging and can deliver up to 350 kW of power. It has a rectangular shape and seven pins and can be plugged into any EV or charging station that supports the CCS standard. It is mainly used in Europe and North America and by some EV manufacturers, such as BMW, Volkswagen, Hyundai, and Kia.

CHAdeMO Plug :

The CHAdeMO plug, also known as the Type 4 plug, is another plug for EV charging. It is compatible with only Level 3 charging and can deliver up to 62.5 kW of power. It has a circular shape and 10 pins and can be plugged into any EV or charging station that supports the CHAdeMO standard. It is mainly used in Japan and Asia and by some EV manufacturers, such as Nissan, Mitsubishi, and Subaru.
