What is Type 1 EV charger?

Electric Vehicles (EVs) are becoming increasingly popular as people look for more sustainable and environmentally-friendly modes of transportation. One essential component of an EV charging infrastructure is the EV charger itself. There are several types of EV chargers available, each with its own specifications and capabilities. In this article, we will delve into the details of Type 1 EV charger.

Type 1 EV charger, also known as SAE J1772 or simply Level 1 charger, is designed for electric vehicles that utilize the Type 1 charging standard. It features a single-phase charging capability and delivers power at up to 7.4 kilowatts (kW), which translates to approximately 25 kilometers of driving range per hour of charge, depending on the vehicle’s efficiency.

Type 1 EV chargers are typically equipped with a standard household plug on one end that can be connected to a regular electrical outlet, while the other end connects to the vehicle's charging port. Due to its lower power output compared to other types of EV chargers, Type 1 chargers are commonly used for overnight or long-duration charging, especially in residential settings.

Key Features and Limitations

Despite being a slower charging option, Type 1 EV chargers have some key advantages. For instance, they are relatively simple and inexpensive to install, as they require minimal electrical upgrades. Additionally, most electric vehicles on the market today come standard with a Type 1 charging port, making it a compatible choice for many EV owners.

However, Type 1 chargers do have their limitations. Their lower power output restricts the charging speed compared to higher-level chargers, such as Type 2 or DC fast chargers. Therefore, they may not be ideal for situations that require rapid recharging, such as public charging stations or long-distance travel.


Type 1 EV charger provides a fundamental and convenient charging solution for electric vehicle owners, particularly in residential settings. While it may not offer the fastest charging speeds, its compatibility and cost-effectiveness make it an appealing option for many. However, as the demand for faster and more efficient charging increases, higher-level chargers like Type 2 or DC fast chargers are gaining popularity, effectively expanding the capabilities of EV charging infrastructure.
