how long to charge ev level 2



Electric vehicles (EVs) are becoming increasingly popular due to their environmental benefits and lower operating costs. However, one of the concerns for potential EV owners is the charging time, especially when using Level 2 charging stations. In this article, we will delve into the details of EV Level 2 charging and explore how long it takes to charge an electric vehicle using this method.

Understanding EV Level 2 Charging

EV Level 2 charging refers to the use of a 240-volt AC power source to charge an electric vehicle. It is the most common and widely available charging option for EV owners. Level 2 charging significantly reduces charging times compared to Level 1 charging, which uses a standard 120-volt household outlet. Level 2 chargers are typically installed in residential homes, commercial buildings, and public charging stations.

The Factors Influencing Charging Time

Various factors affect the charging time of an electric vehicle using Level 2 charging. It is important to consider these factors to estimate how long it will take to charge your EV. Let's take a closer look at the key factors that influence charging time:

1. Battery Capacity and State of Charge

The battery capacity of an electric vehicle is an essential factor in determining the charging time. EVs with larger battery capacities will take longer to charge compared to those with smaller batteries. Additionally, the state of charge (SOC) of the battery also affects the charging time. When the battery is nearly empty, it can charge at a faster rate. However, as the SOC increases, the charging speed gradually decreases to protect the battery's lifespan.

To give you a rough estimate, a typical electric vehicle with a 60 kWh battery capacity and 20% SOC can charge from 0 to 80% in approximately 8-10 hours using a Level 2 charger.

2. Charging Station Capacity

The capacity of the Level 2 charging station also plays a vital role in determining the charging time. Most Level 2 chargers have a maximum power output of 7.2 kW, but some newer models can offer up to 19.2 kW. The higher the charger's capacity, the faster the charging speed will be. It is important to note that your vehicle's onboard charger should match the capacity of the charging station to achieve optimal charging speeds.

3. Battery Technology

Battery technology is constantly evolving, and newer EV models often come with advanced battery systems that support faster charging speeds. The efficiency and design of the battery cells, the cooling system, and other factors can influence the charging time. It is advisable to check the manufacturer's specifications to understand the charging capabilities of your specific EV model.

4. Environmental Factors

Environmental conditions, such as temperature and humidity, can impact the charging time of an electric vehicle. Extreme temperatures, whether hot or cold, can affect the battery's performance and charging speed. Charging an EV in cold conditions may take longer as the battery may need additional energy to warm up. On the other hand, high temperatures may reduce the charging speed to avoid overheating the battery.

5. Preconditioning and Charging Accessories

Some electric vehicles come with features like battery preconditioning, which is the process of adjusting the battery temperature before charging. Battery preconditioning can optimize the charging process and increase the charging speed. Additionally, using charging accessories like a smart charging cable or a charging dock with advanced features can also improve the charging efficiency and reduce the overall time required.


In conclusion, the charging time for an electric vehicle using Level 2 charging depends on several factors, including battery capacity, state of charge, charging station capacity, battery technology, environmental conditions, and the use of charging accessories. It is crucial to consider these factors to estimate how long it will take to charge your EV. As technology continues to advance, we can expect further improvements in charging speeds and efficiencies, making electric vehicles an even more convenient and feasible mode of transportation.
