Why Choosing the Right Amperage for Your Level 2 EV Charger is Important


As electric vehicles (EVs) continue to gain popularity, the need for efficient and reliable charging solutions becomes crucial. Level 2 EV chargers are an excellent option for EV owners looking to recharge their vehicles faster than with a standard Level 1 charger. However, when it comes to Level 2 chargers, one important factor to consider is the amperage. In this article, we will explore the significance of amperage in Level 2 EV chargers and why choosing the right amperage is essential for optimal performance.

The Basics of Level 2 EV Chargers

Level 2 EV chargers are designed to provide faster charging times compared to Level 1 chargers, which typically use a 120-volt outlet. Level 2 chargers operate at a higher voltage, usually 240 volts, allowing for faster charging speeds. These chargers are commonly installed at homes, workplaces, and public charging stations to offer convenience and reduce charging times for EV owners.

Understanding Amperage in Level 2 Chargers

Amperage, often referred to as amps, is a unit of electric current measurement. In the context of Level 2 chargers, the amperage rating determines the charging speed. A higher amperage rating means more power can be delivered to the EV, resulting in faster charging times. Typically, Level 2 chargers have amperage options ranging from 16 amps to 80 amps.

Choosing the right amperage for your Level 2 charger depends on various factors, including your vehicle's charging capabilities, the electrical infrastructure available, and your charging needs. To make an informed decision, let's delve into the factors you should consider when selecting the amperage for your Level 2 EV charger.

1. Vehicle Charging Capabilities

The charging capabilities of your EV play a crucial role in determining the appropriate amperage for your Level 2 charger. Each vehicle model has a maximum charging rate, commonly known as the onboard charger's capacity. This capacity dictates how much power the EV can accept from the charger.

To find your vehicle's charging capabilities, refer to the owner's manual or consult the manufacturer's specifications. It is important to note that while some EVs have onboard chargers capable of handling higher amperages, others may have limitations. Exceeding the onboard charger's capacity may not result in faster charging and can potentially damage your vehicle's charging system.

Consider the maximum charging rate of your EV when selecting the amperage for your Level 2 charger. It is recommended to choose an amperage that aligns with your vehicle's charging capabilities to ensure safe and efficient charging.

2. Electrical Infrastructure

Another important factor to consider is the electrical infrastructure available at the location where you plan to install your Level 2 charger. The amperage rating of your charger must not exceed the capacity of your electrical panel.

Before purchasing a Level 2 charger, it is advisable to consult a qualified electrician to assess your electrical system's capacity. The electrician can determine if any upgrades or modifications are necessary to accommodate the desired amperage level.

3. Charging Needs

Understanding your charging needs is vital in selecting the right amperage for your Level 2 charger. Consider the average daily driving distance, available charging time, and desired charging speed.

If you have a shorter daily commute and ample time for charging overnight, a lower amperage charger may be sufficient. This can minimize the demand on your electrical system and potentially reduce installation costs.

On the other hand, if you have a longer daily commute or limited charging time, a higher amperage charger might be more suitable. This will ensure you can charge your vehicle fully within the available timeframe, providing you with greater flexibility and convenience.

4. Installation Costs

Installation costs can vary depending on the amperage rating of your Level 2 charger. Higher amperage chargers generally require thicker and more expensive electrical wiring. Additionally, if your electrical panel needs upgrading to accommodate the desired amperage, it can significantly add to the installation costs.

Consider your budget alongside your charging needs when deciding on the amperage for your Level 2 charger. While higher amperage might provide faster charging, it may not always be necessary or economically feasible.

5. Future-Proofing

Investing in a Level 2 charger with a higher amperage rating offers a degree of future-proofing. As EV technology evolves, future models may have higher onboard charger capacities, enabling faster charging. By opting for a higher amperage charger now, you can ensure compatibility with upcoming EVs without the need for a charger upgrade.

However, it is essential to strike a balance between future-proofing and practicality. Installing a charger with significantly higher amperage than your current EV's capabilities may result in unnecessary expenses.

In summary, selecting the appropriate amperage for your Level 2 EV charger is vital for optimal charging performance. Consider your vehicle's charging capabilities, the electrical infrastructure available, your charging needs, installation costs, and potential future requirements. By evaluating these factors, you can choose the right amperage that provides efficient, safe, and cost-effective charging for your electric vehicle.


As the demand for electric vehicles continues to rise, it is crucial to have a reliable and efficient charging solution. Level 2 chargers offer faster charging times than standard Level 1 chargers, making them a popular choice among EV owners. However, when selecting a Level 2 charger, the amperage plays a critical role in determining the charging speed.

Choosing the appropriate amperage for your Level 2 EV charger requires careful consideration of several factors, such as your vehicle's charging capabilities, the electrical infrastructure available, your charging needs, installation costs, and future-proofing. By taking these factors into account, you can ensure you have the right charging solution that meets your requirements and provides an optimal charging experience for your electric vehicle.
