The Advantages of Level 2 EV Charger
Level 2 EV chargers represent a significant step forward in the electric vehicle (EV) charging infrastructure, bridging the gap between the slower Level 1 chargers and the much faster but less common DC Fast Chargers (Level 3). Operating at a higher voltage of 240 volts, Level 2 charger offer a practical and efficient charging solution for both residential and commercial settings. They are designed to provide a faster charging experience compared to Level 1 chargers, which typically use a standard 120-volt AC household outlet. This makes Level 2 chargers an ideal choice for EV owners looking to balance charging speed with convenience.
One of the standout features of Level 2 charger is their versatility. They are commonly found in a variety of environments including private homes, workplaces, and public charging stations. With charging speeds that provide approximately 10-60 miles of range per hour of charging, depending on the vehicle and charger specifications, Level 2 chargers significantly reduce the charging time compared to Level 1 chargers. This increase in speed and efficiency is crucial for the widespread adoption of EVs, as it aligns more closely with the refueling experience of traditional gasoline vehicles, thereby enhancing the practicality of owning an EV.
The Technical Aspects of Level 2 EV Charger
Level 2 EV charger represents a significant advancement in EV charging technology, offering a blend of speed and convenience that surpasses the capabilities of Level 1 chargers. Operating at a voltage range of 208 to 240 volts, Level 2 chargers can deliver power outputs ranging up to 19.2 kW in North America and 22 kW in Europe, drastically cutting down charging times compared to the 120-volt Level 1 chargers. For instance, while a 3 kW Level 2 charger can take about 13.3 hours to charge a 40 kWh battery, a more powerful 22 kW charger can accomplish the same in just about 1.8 hours. However, the actual charging time varies depending on factors like the EV's onboard charge acceptance rate and battery size.
The design of Level 2 charger comes in two main types: tethered and untethered. Tethered chargers, popular in North America, feature a permanently attached cable, offering ease of use and immediate readiness for charging, though they can be limited by the cable's length and are prone to wear and tear. On the other hand, untethered chargers, common in Europe, require users to supply their own charging cables, providing flexibility and ease of maintenance but adding the inconvenience of manual cable management. Additionally, Level 2 charging connectors vary regionally, with the Type 1 (J1772) connector used in North America and Japan, and the Type 2 (Mennekes) connector used in Europe and other regions. When installing a Level 2 charger, it's crucial to consult with a qualified electrician to assess the suitability of the home's electrical system and plan for any necessary upgrades.
Types of Level 2 Chargers
Level 2 EV charger is a key component for the best home charging experience, offering a balance between speed and convenience. When considering the installation of a Level 2 EV charger, homeowners have two primary options: tethered and untethered.
