To give an idea of the charging time, fully charging a battery electric vehicle (BEV) through Level 1 charging may take around 40-50+ hours to reach 80% charge from empty. On the other hand, plug-in hybrid electric vehicles (PHEVs) can be charged within a shorter time frame of approximately 5-6 hours.
Overall, while Level 1 charging provides a convenient and accessible way to charge an electric vehicle, it is best suited for those with limited charging needs or shorter daily commutes, as it lacks the speed and efficiency required for quick or frequent charging.
Level 2 Charging: Faster and More Efficient
Level 2 charging is a significant step up in the world of EV charging levels explained. It offers a faster and more efficient way to charge electric vehicles, making it ideal for both EV drivers and those on long-distance travels. Utilizing a 240-volt outlet, a Level 2 charging station can provide a charging rate of approximately 10 to 30 miles of range per hour, depending on the specific electric vehicle and power output of the station. This type of charging is widely available for home, workplace, and public use, making it convenient for EV drivers wherever they go. However, Level 2 charging does require specialized equipment, such as a Level 2 EV charging station, and may require electrical capacity upgrades. Fortunately, there are various incentives available to help offset the installation cost, making it a viable option for more EV owners.
Level 2 chargers are known for their ability to provide rapid AC power through 240-volt or 208-volt electrical service, making them an efficient choice for EV drivers. With a Level 2 EV charger, a battery electric vehicle (BEV) can charge up to 80 percent from empty in approximately 4 to 10 hours, while a plug-in hybrid electric vehicle (PHEV) can achieve a full charge in just 1 to 2 hours. This makes Level 2 charging a practical solution for those who need a quick charge, whether at home, work, or in public places. Overall, Level 2 charging offers a balance between convenience and charging speed, catering to the needs of EV drivers across different scenarios and contributing to the growth of the electric vehicle industry.
Level 3 or DC Fast-Charging: The Speedy Solution
Level 3 charging, also known as DC fast charging, is a crucial component of electric vehicle charging infrastructure. This high-voltage DC level charging method delivers rapid charging, offering up to 180-250 miles of range per hour. Level 3 charging stations are specifically designed to cater to the needs of EV drivers, particularly during long-distance journeys or when charging EV fleets. These charging stations play a significant role in public charging requirements, ensuring convenience for travelers on the go. However, it is worth noting that Level 3 charging is the most expensive option and suffers from limited availability compared to other charging levels.
For electric car owners, Level 3 charging stations are a game-changer, making long-distance travel more accessible than ever before. Major providers like Tesla’s Supercharger network, EVgo, and Electrify America have established Level 3 charging stations across the country, expanding the reach of electric vehicle charging infrastructure.
