Level 2 EV Charger Types by Installation Methods

Level 2 electric vehicle (EV) chargers come in various types based on their installation methods, offering flexibility and convenience for EV owners. One common type is the wall-mounted charger, which is installed directly onto a wall surface, typically in a garage or parking area. These chargers are compact and space-saving, making them ideal for residential use. They require a dedicated electrical circuit and professional installation to ensure proper wiring and safety compliance. Wall-mounted chargers offer the advantage of convenience, allowing EV owners to easily plug in their vehicles for charging at home without the need for additional hardware or infrastructure.

Another type of Level 2 EV charger is the pedestal-mounted charger, which is installed on a freestanding pedestal or post. These chargers are commonly found in public spaces such as parking lots, shopping centers, and workplaces, providing EV owners with convenient access to charging while on the go. Pedestal-mounted chargers may feature multiple charging ports, allowing multiple vehicles to charge simultaneously. They require a sturdy foundation and access to electrical power, making installation more complex compared to wall-mounted chargers. However, they offer the advantage of flexibility, allowing for easy relocation and scalability to accommodate growing demand for EV charging infrastructure.

Additionally, some Level 2 EV chargers are designed for portable installation, allowing for temporary or on-the-go charging solutions. These chargers typically come with a plug that can be connected to a standard electrical outlet, eliminating the need for dedicated wiring or installation. Portable Level 2 chargers offer the advantage of versatility, allowing EV owners to charge their vehicles wherever there is access to a power source. They are particularly useful for travelers, renters, or EV owners without access to dedicated charging infrastructure. However, portable chargers may have lower power output compared to wall-mounted or pedestal-mounted chargers, resulting in longer charging times. Overall, the various types of Level 2 EV chargers offer different installation methods to suit the diverse needs and preferences of EV owners, providing convenient and accessible charging solutions for electric vehicles.

Level 2 EV Charger Types by Connectors and Plugs

Level 2 electric vehicle (EV) chargers come in different types based on their connectors and plugs, catering to the various charging standards and requirements worldwide. One common type is the Type 1 connector, also known as J1772. This connector is widely used in North America and Japan and features a single-phase AC charging capability. Type 1 connectors are characterized by their ergonomic design and compatibility with most EV models from major manufacturers. They typically have a lockable mechanism for secure connection and can deliver power at various levels, making them suitable for both residential and public charging applications.

In Europe and other regions, the Type 2 connector, also known as Mennekes, is the predominant choice for Level 2 EV charging. Type 2 connectors support single-phase and three-phase AC charging, offering greater flexibility and compatibility with a wide range of EV models. They feature a more robust design compared to Type 1 connectors and are equipped with additional communication pins for data exchange between the EV and charging station. Type 2 connectors are commonly used in public charging infrastructure and are gradually becoming the standard for residential installations as well.

In China, the GB/T connector is the prevailing standard for Level 2 EV charging. This connector is similar to Type 2 in terms of functionality but has different physical dimensions and pin configurations to accommodate the Chinese market's specific requirements. GB/T connectors support both single-phase and three-phase AC charging and are commonly found in public charging stations across China. They play a crucial role in supporting the rapid growth of the EV market in the region and ensuring interoperability among different EV models and charging infrastructure.

In North America, there is also the NACS (North American Charging Standard), which aims to establish a unified charging standard for Level 2 EV chargers. NACS connectors are designed to be compatible with both Type 1 and Type 2 plugs, offering versatility and interoperability across different charging networks. They support single-phase AC charging and feature standardized communication protocols to facilitate seamless integration with EVs and charging stations. NACS connectors are increasingly adopted in North America to streamline the EV charging experience and promote the widespread adoption of electric vehicles.

Speeds and Charging Time of Level 2 EV Charging

Level 2 electric vehicle (EV) charging is known for its faster charging speeds compared to Level 1 charging, making it a popular choice among EV owners. The charging time of Level 2 EV charging varies depending on several factors, including the power output of the charging station, the capacity of the vehicle's battery, and the state of charge (SOC) of the battery when charging begins. According to the U.S. Department of Energy, Level 2 charging stations typically deliver power output ranging from 3.3 kilowatts (kW) to 19.2 kW, with higher power levels resulting in faster charging times.

The charging time of a Level 2 EV charger can be estimated using a simple formula: charging time (hours) = battery capacity (kWh) / charging power (kW). For example, if a vehicle has a battery capacity of 60 kWh and is charged using a Level 2 charging station with a power output of 7.2 kW, the estimated charging time would be approximately 8.3 hours. However, it's essential to note that this is a theoretical calculation, and actual charging times may vary based on factors such as charging efficiency, temperature, and battery management systems.

According to data from the Electric Vehicle Charging Association (EVCA), Level 2 EV charging can provide an average charging rate of approximately 10 to 20 miles of range per hour of charging, depending on the vehicle and charging station specifications. For example, a Level 2 charging station with a power output of 7.2 kW can provide roughly 25 miles of range per hour of charging for a vehicle with a 60 kWh battery. This charging rate offers significant convenience for EV owners, allowing them to replenish their vehicle's battery quickly and efficiently, whether at home, work, or public charging stations, including Tesla destination charger.

So, Level 2 EV charging offers faster charging speeds compared to Level 1 charging, with charging times ranging from several hours to overnight, depending on the power output of the charging station and the capacity of the vehicle's battery. With an average charging rate of 10 to 20 miles of range per hour of charging, Level 2 charging provides EV owners with convenient and efficient charging solutions for their electric vehicles, helping to promote the widespread adoption of clean and sustainable transportation.

    Not so much a comment but a question.

    Is there such a thing as reverse level 2 charging, in a scenario where the electrical grid is down and I wish to run my house of the car’s battery.

    The steps I would see:
    1) disconnect the grid feed to the house electrical panel.
    2) flip all breakers to off
    3) plug car into level 2 charger and put the car in utility mode.
    4) flip something on the level 2 charger to enable utility mode to feed the electrical panel
    5) flip the critical breakers in the electrical panel for fridge/freezer and any other must-haves
    6) when the power grid is back, turn off the car to electrical panel feed at the level2 charger
    7) turn on the electrical grid connection the the electrical panel
    8) turn on all the breakers to restore power to the house

    Does such a capability exist, and if so which level 2 chargers work like this?
