AC EV Charger Levels of Electric Vehicles Explained

p> Author:evcome-Ev Charging Stations Manufacturer


Electric vehicles (EVs) are rapidly becoming more popular on our roads due to their emission-free performance and lower running costs. One key component of EV technology is the AC charger, which refuels the vehicle's battery from the mains electricity supply. There are different levels of AC EV chargers depending on the power output, which can affect the charging time and convenience.

In this article, we'll explain the levels of AC EV chargers and how they affect the charging process. By the end of this article, you will have a good understanding of which EV charger level is suitable for your vehicle and driving habits.

Level 1 EV Charger

The Level 1 EV Charger is the most basic type of AC charger, commonly referred to as the "trickle" charger. This charger is usually included with the vehicle and works with a standard 120-volt household outlet. The Level 1 charger delivers 1.4-1.9 kW of power, which translates to around 4 to 6 miles of driving range per hour of charging time. Therefore, it may take 8-14 hours to fully charge an EV from empty to full, which is why this charger is mostly used for overnight charging.

Level 2 EV Charger

The Level 2 EV Charger is a more powerful AC charger that can deliver up to 19.2 kW of power, which translates to around 20-80 miles of driving range per hour of charging time. This charger requires a dedicated 240-volt outlet, which is typically installed in a garage or car park.

The Level 2 EV Charger can charge an EV much quicker compared to the Level 1 charger, with some models taking just 4-6 hours to fully charge. This faster charging speed makes the Level 2 charger a more convenient option for those who drive their EV frequently.

Level 3 DC Fast Charger

The Level 3 DC Fast Charger is the fastest type of EV charger available, with the ability to charge an EV battery from empty to 80% in just 20-30 minutes. This charger uses a DC (direct current) power supply instead of the AC power supply used by Level 1 and 2 chargers.

The Level 3 charger can deliver up to 150 kW of power, which translates to around 200-300 miles of driving range in just 60 minutes of charging time. This makes the Level 3 charger perfect for long-distance travel, where frequent recharging is necessary.

However, the Level 3 charger requires a more sophisticated power system and is more expensive to install, which is why it is mostly available at public charging stations rather than in private homes.

Factors That Affect Charging Time

While the type of charger plays a significant role in the charging time, other factors can affect the process, such as:

Battery Capacity: The larger the battery capacity, the longer it will take to recharge.

State of Charge: The less empty your battery is, the longer it takes to recharge.

Temperature: The temperature can affect the battery's charging speed. If the battery is too cold or too hot, the charging will be slower.

EV Model: Different EV models have different charging capabilities and requirements.


As you can see, the level of AC EV charger you need depends largely on your driving habits and lifestyle. If you drive only occasionally or have access to a Level 3 charging station, then the Level 1 charger may be sufficient. However, if you drive frequently and require quick and convenient charging at home, a Level 2 charger is the way to go.

Keep in mind that upgrading the charger level may require electrical upgrading and installation costs. Therefore, make sure to consult a professional electrician and EV dealer before making any decision. With the right level of AC EV charger, you'll enjoy a more comfortable EV driving experience.
