what is level 2 ev charger



Electric vehicles (EVs) are gaining popularity worldwide as people are becoming more conscious about their carbon footprint and looking for environmentally friendly transportation alternatives. However, one of the concerns for potential EV owners is the charging infrastructure. Level 2 EV chargers have emerged as a reliable and convenient solution for charging electric vehicles at home, workplaces, and public places. In this article, we will explore what exactly a level 2 EV charger is, how it works, its advantages, installation requirements, and its compatibility with different electric vehicles.

The Basics of Level 2 EV Chargers

Level 2 EV chargers are a type of charging equipment that provides faster charging capabilities compared to the standard Level 1 chargers. They are called Level 2 because they deliver power at 240 volts, which is twice the voltage of a regular household outlet. These chargers require a dedicated circuit and are typically hardwired to a home's electrical system or connected through a charging station.

Level 2 EV chargers come with a variety of power ratings, ranging from 16 amps to 80 amps. The higher the power rating, the faster the charging speed. However, it's important to note that the charging speed also depends on the electric vehicle's onboard charger capabilities. Most electric vehicles can handle a 40-amp Level 2 charger, which provides a good balance between charging speed and cost.

Advantages of Level 2 EV Chargers

Level 2 EV chargers offer several advantages over Level 1 chargers and conventional household outlets.

1. Faster Charging Speeds and Convenience

One of the biggest advantages of Level 2 EV chargers is their faster charging speeds. Compared to Level 1 chargers, which typically deliver around 3-5 miles of range per hour of charging, Level 2 chargers can provide up to 25 miles of range per hour. This means that you can charge your vehicle overnight and wake up with a fully charged battery, ready for your daily commute.

2. Versatility and Compatibility

Level 2 EV chargers are compatible with a wide range of electric vehicles, making them a reliable choice for EV owners. Whether you own a Tesla, Nissan Leaf, Chevrolet Bolt, or any other electric vehicle on the market, you can find a Level 2 charger that suits your needs.

3. Cost-Effectiveness

While Level 2 chargers may require a higher upfront cost compared to Level 1 chargers, they offer better long-term cost-effectiveness. By providing faster charging speeds, they help maximize the driving range of your electric vehicle without relying on public charging infrastructure, which often comes with additional costs.

4. Energy Efficiency

Level 2 EV chargers are more energy-efficient compared to Level 1 chargers. They convert electrical energy more efficiently into a form that can be stored in the vehicle's battery. This efficiency not only helps reduce energy waste but also saves you money on your electricity bills in the long run.

5. Customization and Smart Features

Many Level 2 EV chargers come with customization options and smart features. These include programmable charging schedules, WiFi or cellular connectivity for remote monitoring and control, and integration with smart home systems. These features allow you to optimize your charging experience based on your specific needs and take advantage of off-peak electricity rates.

Installation Requirements for Level 2 EV Chargers

Before installing a Level 2 EV charger, there are a few important considerations to keep in mind.

1. Electrical Service Panel

Level 2 chargers require a dedicated circuit from your home's electrical service panel. Depending on the power rating of the charger, you may need a 40-amp, 50-amp, or even 80-amp circuit breaker. An electrician can assess your electrical panel's capacity and make the necessary upgrades if needed.

2. Location and Mounting

Deciding on the location and mounting of your Level 2 charger is crucial. Ideally, it should be installed near where you park your electric vehicle. The charger should be mounted on a sturdy wall or a dedicated charging station with proper ventilation and protection from the elements.

3. Electrical Wiring

Proper electrical wiring is essential for the safe and efficient operation of a Level 2 EV charger. It's recommended to hire a licensed electrician who can ensure that the wiring is correctly sized, the connections are secure, and all the necessary safety precautions are taken.

4. Utility Connection and Permits

In some cases, you may need to upgrade your utility connection to support the increased power demand of a Level 2 charger. Additionally, obtaining the required electrical permits from the local authorities is essential to ensure compliance with safety standards and regulations.

Compatibility with Electric Vehicles

Level 2 EV chargers are compatible with most electric vehicles available today. Electric vehicle manufacturers provide specific charging information for their models, including the maximum charging rate and compatibility with different charger power ratings.

It's important to note that while Level 2 chargers are compatible with a wide range of electric vehicles, Tesla vehicles require an additional adapter for compatibility with non-Tesla chargers. This adapter allows Tesla owners to use Level 2 chargers that have a standard SAE J1772 connector.


Level 2 EV chargers offer faster charging speeds, convenience, cost-effectiveness, and customization options compared to Level 1 chargers and regular household outlets. They provide an efficient and effective way to charge electric vehicles at home, workplaces, and public places. However, it's essential to consider the installation requirements and compatibility with your electric vehicle before purchasing a Level 2 charger. By investing in a Level 2 EV charger, you can enjoy the benefits of faster and more convenient charging, ultimately enhancing your overall electric vehicle ownership experience.
