The Difference Between Level 1 and Level 2 EV Chargers: Which is Right for You?
On this page
As electric vehicles (EVs) become more common, many car owners are faced with the decision of which type of home charger to install. While most electric vehicle manufacturers provide a Level 1 charger with the car, upgrading to a Level 2 EV charger can offer a significant improvement in both convenience and efficiency. In this article, we’ll explore the differences between Level 1 and Level 2 chargers, highlighting their speed, functionality, and advantages, to help you make an informed decision on which EV charger is best suited to your needs.
However, this simplicity comes with a significant trade-off in terms of charging speed. A Level 1 charger is typically rated between 2 to 5 kilowatts (kW), which results in a charging rate of about 3 to 5 miles of range per hour. This means that, depending on the size of your battery, it can take quite a long time to fully charge your EV with a Level 1 charger. For a fully electric vehicle (BEV), this can mean anywhere from 40 to 60 hours for a full charge when charging from empty.
For plug-in hybrid electric vehicles (PHEVs), the situation is somewhat better. Since PHEVs have smaller batteries, they can generally be fully charged in about 5 to 6 hours with a Level 1 charger. Even though this may seem like a long time, PHEV owners usually don’t need to charge the car to 100% every day, so Level 1 charging can still be sufficient for daily use.
For people with a lower daily driving range or those who do not mind waiting overnight for their vehicle to charge, a Level 1 charger can be a good choice. However, the slow charging speed may not be suitable for those who rely on their EV for longer trips or need faster turnaround times.
With charging speeds ranging from 7 kW to 19.2 kW, a Level 2 charger can add an average of 32 miles of range per hour of charging. This makes it about 8 times faster than a Level 1 charger. A typical Level 2 charger can fully charge an EV from empty to full in about 4 to 8 hours, depending on the vehicle’s battery size and the charger’s output.
For most drivers, a Level 2 charger offers a much more practical and time-efficient charging solution, especially for those who drive their EVs daily or have larger battery capacities. For example, if you return home in the evening and plug in your car overnight, you can expect it to be fully charged by the morning, ready for the next day’s commute.
In contrast, a Level 1 charger will typically only add around 3 to 5 miles of range per hour of charging. This means that a Level 2 charger can charge your EV up to 8 times faster than a Level 1 charger.
For those who need to fully charge their vehicle overnight or during the day, Level 2 chargers provide the efficiency and speed needed to get the job done quickly. With charging times of 4 to 8 hours for most EVs, you’ll be able to rely on your car for daily use without having to worry about long charging times.
While the initial cost of installing a Level 2 charger can be higher than a Level 1 charger—due to the need for a 240V outlet and potential electrical upgrades—many EV owners find the benefits to be well worth the investment. Faster charging, added convenience, and the ability to save money by charging during cheaper electricity times can make a Level 2 charger an excellent addition to your home.
A Level 2 charger is like having a personal gas station in your garage, offering faster charging times, more flexibility, and often the ability to charge your EV at a lower cost by utilizing off-peak electricity hours. With a Level 2 charger, you’ll spend less time waiting for your car to charge and more time enjoying the road ahead.
In today’s world of electric vehicles, upgrading to a Level 2 charger is an investment that will pay off in convenience, efficiency, and savings over time.
What is a Level 1 EV Charger?
A Level 1 EV charger is the most basic and common type of home charging solution for electric vehicles.
