As electric vehicles (EVs) gain popularity, one of the essential considerations for EV owners is understanding the types of charging stations available. Two primary categories that often come up in discussions are Level 1 and Level 2 chargers. These chargers differ significantly in terms of charging speed, installation requirements, and overall convenience. Let's delve into the specifics to understand their differences and how they impact the EV ownership experience.
But what exactly is a Level 2 car charger and why does it present better value than its Level 1 counterpart?

What is Level 2 Charging?
Level 2 charging represents a substantial upgrade over basic Level 1 charging commonly provided with EV purchases. While Level 1 chargers operate on standard 120-volt outlets, Level 2 chargers require a 240-volt power source and use a dedicated circuit, offering faster and more efficient charging capabilities akin to having your personal gas pump at home.
The currently popular Level 2 charging stations on the market are rated at 32A/40A/48A, and the current is backward compatible. For example, if you choose a 48A charging station, you can also use 40A and 32A.
How Fast is a Level 2 EV Charger?
The speed difference between Level 1 and Level 2 chargers is substantial. With Level 1 chargers delivering about 4 miles of range per hour of charge, Level 2 chargers impressively offer an average of 32 miles of driving range per hour of charge. This translates to charging up to 8 times faster, significantly reducing the time required to fully recharge your EV.
Benefits of Level 2 Charging
-
Faster Charging Times: Level 2 chargers deliver between 6.2 to 19.2 kW of power compared to the 1.2 kW output of Level 1 chargers. This substantial increase in power significantly reduces charging durations, making Level 2 chargers ideal for everyday use and longer trips.
-
Cost Savings and Customization: Level 2 chargers can be optimized to take advantage of lower electricity rates, reducing charging costs. Additionally, smart Level 2 chargers like the EvoCharge iEVSE Home Smart EV Charger allow for customized charging schedules via a mobile app, maximizing efficiency and potentially qualifying for further rebates or incentives.
Installing a Level 2 EV Charger at Home
To install a Level 2 EV charger at home, follow these steps:
-
Check Electrical Requirements: Ensure your home has a 240-volt outlet or circuit suitable for Level 2 charging. If not, hire a certified electrician to install one.
-
Explore Rebates and Incentives: Many local, federal, or utility companies offer rebates and financial incentives for Level 2 charger installation or usage.
-
Utilize Smart Features: Take advantage of mobile apps offered by smart Level 2 chargers to customize charging schedules, monitor usage, and potentially reduce overall charging costs.
In conclusion, Level 2 EV chargers represent a significant upgrade in charging speed and efficiency, offering EV owners a more convenient and cost-effective way to charge their vehicles. With faster charging times and potential cost savings through smart features, Level 2 chargers are a valuable investment for enhancing the EV ownership experience.
