Best Level 2 EV Charger

Electric vehicles (EVs) are a great investment for mobility, they consume less power, use energy more efficiently, and release fewer or no CO2 or greenhouse emissions. Whether you are looking to charge an EV with renewable energy or regular power from the grid, it is important to have the right Electric Vehicle Supply Equipment (EVSE), better known as an EV charger.

A Level 2 car charger is highly efficient since it can juice up the battery of an EV in less time than regular chargers, allowing EVs to be road-ready in just a few hours. In this article, we answer some of the top questions regarding Level 2 electric car chargers and explain why they might be the best option for you.

Types of EV Charging Connectors

EV chargers may require dedicated circuits to charge. This means dedicated wiring, a protection system (breaker), and an outlet that matches the voltage of the charger. In this section, we explain the different types of outlets used for EV charging.

Types of 120 Volt Outlets

A Level 1 EV charger does not regularly require a dedicated circuit, since most homes feature 14 AWG or 12 AWG gauge wires for their 120V wirings. This means that homes can support loads of 15 amps (1.8kW) with 14 AWG wirings and 20 amps (2.4kW) with 12 AWG wires.

A 120V 15 amp circuit uses regular (NEMA 5-15R) outlets, while 20 amp circuits require a 20 amp outlet (NEMA 5-20R) that features a T-shaped receptacle. Since Level 1 EV chargers demand around 1kW (8.3 amps) to 2kW (16.67 amps), they can usually be connected to conventional 120V outlets.

240V Car Charger: Types of 240 Volt Outlets

A level 2 car charger operates at a voltage of 240V and delivers a rated power going from 3kW up to 7kW for residential applications, while commercial applications go up to 19kW. This means that level 2 electric vehicle chargers require 10 AWG wires (30 amps) or higher gauges and receptacles that can support 30 amps (7kW) for residential applications or 80 amps (19kW) for commercial ones.

There are three main 240V outlets used to power a level 2 EV charging station in residential applications, the NEMA 6-50 (240V/50 Amps), NEMA 14-30 (120V & 240V/30Amps), and the NEMA 14-50 (120V & 240V/50 amps). A 240V car charger demanding more than 50 amps is not suited for residential applications, requiring a more complex and robust electrical infrastructure.

The Fundamental Difference Between Level 1 and Level 2 Chargers for Electric Cars

Level 1 and level 2 charging stations are entirely different. The most fundamental difference between them is their rated power, level 1 chargers go as high as 2kW, while the level 2 charging station delivers up to 7kW for residential applications or up to 19kW in commercial ones. This results in level 1 chargers taking up to 50 hours to charge an EV, while level 2 EV chargers do it overnight or in just a few hours.

The different rated power is the result of both EV charging stations operating at different electrical parameters (voltage and current). Level 1 EV chargers operate at 120V and deliver a current of up to 16 amps, while a Level 2 charging station operates at 240V and delivers a current of 30 amps for most residential applications and up to 80 amps for commercial ones.

What to Look for When Buying a Level 2 Charger

To get the best Level 2 EV charger that adapts to your charging needs, you should know what to look for. In this section, we explain some important aspects to consider when acquiring these chargers.

Cable Length

Most level 2 EV chargers are tethered (including a built-in charging cable), which is why considering the length of the cable should be an important factor. The charging cable should comfortably sit between the EV charging port and your EV charger. This will avoid the cable from being pulled and get damaged in the long run.

Smart Capabilities

While it is not imperative, acquiring an EVSE with smart capabilities can be of great help, since these can come in handy. Some smart capabilities include configuring the charging schedule for your EV, monitoring the charging in real time, and more.

Some of the best smart features that you might find are Power Sharing, Solar Smart Charging, RFID authentication, load management features with Time-of-Use optimization. Each of these functions improves the EV charging experience by granting you more control over the whole process.


Certified EV chargers ensure you get an EVSE in compliance with the National Electric Code (NEC) and the National Fire Protection Association (NFPA) regulations. Some important certifications include the UL certification (UL2594 and UL2231-1), TÜV SÜD certification, EV Connect certification, or the ENERGY STAR certification.

Most certifications test EV chargers against safety standards and regulations, ensuring they comply with all standards, safety, and NEC regulations. ENERGY STAR even tests EV chargers against energy efficiency to ensure energy savings and lower Greenhouse Gas (GHG) emissions.

Outdoor Use

Not all EV drivers have enough space availability to charge the EVs indoors, which is why selecting an EV charger that is rated for both indoor and outdoor usage, can be of great help. Most EV chargers featuring an Ingress Protection (IP) rating of IP65 or IP66, are excellent for outdoor usage. This is an essential feature for commercial applications.

How To Test EV Chargers?

To ensure an EV charger is working as it should, we can test them using a measurement device such as the Fluke FEV100, an electrical measuring tool designed to test EV chargers. Some testing considerations include:

  • Safety: Safety tests include Ground Fault Current Interruption trip tests to ensure safety against electric shocks, other tests include ground fault detection and Protective Earthing (PE) tests at the terminal.
  • Operability: Tests performed with the Fluke FEV100 include measuring the operating voltage and current. This ensures the EV charger will charge the EV at the right electrical parameters.
  • Simplicity and functionality: Additional tests are performed to verify the EV charging stations are easy to use considering standards and that they deliver a good performance on their charging features.

Level 2 EV Charger: Most Common Questions

New EV drivers tend to have several doubts regarding level 2 electric vehicle charging stations. In this section, we aim to answer some of the most common questions regarding these types of chargers.

Are All Level 2 Chargers the Same?

While it is true that practically all level 2 EVSE chargers feature a J connector under the IEC 62196-1 legislation, 240 volt car chargers vary between models and manufacturers. The main difference between Level 2 240 volt chargers is the different power ratings as explained in the following section, but that is not all. Models can differ in features, power management availability, mounting options, warranties, integrated electrical protections, reliability, and more.

Are Level 2 Chargers the Best Charging Option for Your EV?

If you are looking to charge your vehicle in as little time as possible, a DCFC would be the best choice, since they can feature high-power rates of up to 50kW. However, DCFCs incur a very high capital cost and require a large electrical infrastructure upgrade from the utility increasing costs and causing project delays. This makes them unviable in many cases.

On the other hand, installing the best level 2 EV charger can deliver many advantages. In most cases, a 240V EV charger used for residential and commercial applications will only require a dedicated circuit branch to supply the right voltage and power rate. Only when multiple level 2 EVSE chargers are needed is when a main panel upgrade may be required depending on your electrical infrastructure. Aside from that, a 240V electric car charger can be as easy to install as a level 1 charger, while granting a faster charge speed for your EV. A level 2 electric vehicle charger provides the best balance between cost and performance in the industry.

How Fast Are Level 2 Chargers?

The level 2 240 volt charging stations are extremely fast compared to regular Level 1 chargers. The most common 240V charging station features a power rate of 6kW, but Level 2 chargers can feature power ratings going from 3kW up to 20kW.

Charging speed in kilowatt-hour per mile varies between EV models. For instance, charging a 2021 Tesla Model 3 Standard that features a 24kWh/100miles power usage and 62.3kWh battery with a 3kW 240 volt EV charger, will charge 12.5 miles in one hour for a total charging time of 20 hours. The best level 2 charger featuring a 20kW power rate, charges 83 miles in a single hour for a total charging time of 3 hours.
