What is Slow Charging? Understanding Level 1 Charging
Slow charging, often called Level 1 charging, is the most basic way to charge an electric vehicle (EV). It uses a standard household outlet, the kind you use for lamps and appliances. This is a very convenient option for those who have access to an outlet at home, such as in a garage or driveway. Level 1 charging is sometimes called trickle charging because the electrical current is relatively low compared to other charging methods. This results in a slower charging time, which is usually measured in hours rather than minutes.
Slow charging is usually a 120-volt system, which delivers a lower amount of power to the car. Because the power is limited, it takes a long time to charge a completely depleted battery. However, slow charging is a great choice if you have the time and are charging overnight or when the car isn’t in use. Think of it like gently refilling a water bottle versus using a fire hose. Both will fill it, but the flow rate is dramatically different.
The Basics of Level 1 Charging
Level 1 charging is often overlooked, but it plays a significant role in EV ownership. It offers a convenient charging solution for many EV drivers. It is important to know its functions, advantages, and limitations. Here are some key points:
- How it Works: Level 1 charging uses the standard 120-volt outlet found in most homes. It comes with a charger that plugs into the wall and then connects to the EV. The charger converts the AC power from the outlet to DC power for the car’s battery.
- Charging Speed: The charging speed is relatively slow. You can usually add about 3 to 5 miles of range per hour of charging. This means that a full charge can take up to 24 hours, depending on the battery size.
