What is a Level 2 EV Charger and How Many Amps Does It Have?

Electric vehicles (EVs) are becoming increasingly popular due to their environmental benefits and lower operating costs. As a result, there is a growing need for efficient and fast-charging infrastructure. Level 2 EV chargers have emerged as a popular choice among EV owners due to their faster charging times compared to Level 1 chargers. One common question that arises is "how many amps is a Level 2 EV charger?" In this article, we will delve into the world of Level 2 EV chargers and explore their amp capacity in detail.

Understanding Level 2 EV Chargers

Level 2 EV chargers are the next step up from the basic Level 1 chargers that often come with electric vehicles. While Level 1 chargers use a standard 120-volt alternating current (AC) power source, Level 2 chargers require a 240-volt power source. This higher voltage allows for faster charging times, making Level 2 chargers more convenient and practical for everyday use.

Level 2 chargers are typically installed at homes, workplaces, and public charging stations, providing EV drivers with a reliable and efficient charging option. Compared to Level 1 chargers, Level 2 chargers can charge an electric vehicle up to six times faster, depending on the EV's battery capacity and the charger's amp rating.

The Amp Capacity of Level 2 EV Chargers

Now let's address the main question at hand: how many amps is a Level 2 EV charger? The amp capacity of a Level 2 charger can vary, ranging from as low as 16 amps to as high as 100 amps. The amp capacity determines how much power the charger can deliver to your EV in an hour.

Let's break down the available amp capacities commonly found in Level 2 EV chargers:

1. 16-Amp Level 2 Chargers

A 16-amp Level 2 charger is the most basic option available. It offers a charging rate of approximately 3.8 kilowatts (kW) per hour, allowing for an average charging time of 8 to 11 hours for a vehicle with a 40 kWh battery. While this amp rating works well for commuters or drivers with smaller battery capacities (such as plug-in hybrid electric vehicles), it may not provide sufficient charging power for those with larger battery-capacity EVs.

2. 24-Amp Level 2 Chargers

A step up from the 16-amp chargers, 24-amp Level 2 chargers offer a higher charging rate of around 5.8 kW per hour. This translates to a reduced charging time compared to 16-amp chargers. With a 40 kWh battery, you can expect to fully charge your EV in approximately 5 to 7 hours using a 24-amp charger. The 24-amp option is an excellent choice for EV owners who want faster charging times without investing in the highest amp capacities available.

3. 32-Amp Level 2 Chargers

32-amp Level 2 chargers are a popular choice among EV owners looking for increased charging speeds. With a charging rate of about 7.7 kW per hour, 32-amp chargers offer even shorter charging times compared to their lower amp counterparts. A 40 kWh battery can be fully charged in approximately 4 to 5 hours using a 32-amp charger. This makes it a suitable option for EV owners who require more frequent and quicker charging sessions.

4. 40-Amp Level 2 Chargers

Stepping up the amp ladder, 40-amp Level 2 chargers provide a rapid charging rate of about 9.6 kW per hour. With a 40 kWh battery, you can expect to attain a full charge in approximately 3 to 4 hours using a 40-amp charger. This amp capacity is highly beneficial for EV owners with larger battery capacities who need to charge their vehicles quickly, particularly in situations where time is of the essence.

5. High-Amp Level 2 Chargers

For those seeking the highest charging speeds available, high-amp Level 2 chargers come into play. These chargers can range from 50 amps all the way up to 100 amps or more. The higher the amp capacity, the quicker the charging time. High-amp chargers are ideal for EV owners who require extremely fast charging, such as those driving long distances or relying heavily on their vehicles for business purposes.

The Importance of Proper Electrical Installation

It is crucial to ensure that the electrical infrastructure at your desired charging location can accommodate the selected amp capacity of the Level 2 charger. Before installing a charger, it is recommended to seek professional assistance from a licensed electrician. They will assess the electrical panel's capacity, wiring, and other factors to determine whether any upgrades or modifications are necessary to support the desired amp rating of the charger.

The Impact of Amp Capacity on Charging Speed

The amp capacity of a Level 2 charger directly impacts the charging speed of your electric vehicle. A higher amp rating provides more power to your EV, resulting in faster charging times. However, it is important to note that the charging speed is limited by the vehicle's onboard charger and the EV's battery capacity. For example, if your EV's onboard charger can only handle a maximum charging rate of 6 kW, there will be no benefit in using a 40-amp charger capable of delivering up to 9.6 kW.

It is essential to match the charger's amp rating to the maximum charging capacity supported by your EV's onboard charger. Consulting your vehicle's manual or reaching out to the manufacturer will help you determine the optimal charging rate your EV can handle.

In Conclusion

Level 2 EV chargers have become the go-to option for EV owners looking for faster and more convenient charging. The amp capacity of a Level 2 charger plays a crucial role in determining the charging speed, with options ranging from 16 amps to 100 amps or more. Choosing an appropriate amp rating that aligns with your EV's charging capabilities and battery capacity is essential for efficient charging. Proper electrical installation is vital to ensure the safety and compatibility of the charger with your electrical infrastructure.

Whether you opt for a 16-amp charger or invest in a high-amp charger, the convenience and flexibility of Level 2 charging will undoubtedly enhance your electric vehicle ownership experience, making it more viable and practical for daily use.
