How Long Do Electric Vehicles Take to Charge? A Comprehensive Guide

How Long Do Electric Vehicles Take to Charge

Electric cars are becoming more and more popular as people become more environmentally conscious and want to save money on gas. But how long does it take to charge an electric car? Unfortunately, there’s no simple answer because many variables are involved, such as the size of the battery in the EV, the charging rate of its onboard charger, and the power source you’re using. In this comprehensive guide, we’ll break it down for you and help you precisely define how long it takes to charge your electric vehicle!


3 Levels of EV Charging

The charging duration of your EV depends on its charging source. There are three levels of EV  charging, according to the Society of Automotive Engineers (SAE International): Level I, Level II, and DC fast charging. The latter is often referred to as Level III, though it isn’t officially stated as such.

Level I (AC)

AC, or alternating current, is the most readily available means of charging an EV. Unfortunately, Level I is the slowest way to charge an EV because it uses the standard 120-volt outlet that you have in your home. Most EVs come with a Level I charger, which is the cheapest way to charge your car.

That being said, it’s important to note that Level I charging is only recommended for topping off your EV’s battery because it will take a very long time to charge it from empty. For example, it would take over 24 hours to charge a Tesla Model S 75D with a standard Level I charger.

Level II (AC)

While similar, Level II (AC) charging is much faster than Level I because it uses a 240-volt outlet, like the ones you see in many homes for clothes dryers and electric stoves. This increased voltage allows more electrons to flow through the wires and into your EV’s battery, which translates to a faster charge.

Level II charging stations come in two forms: standalone units and EVSEs (electric vehicle supply equipment). The former is larger, more expensive, and can charge multiple EVs at once, while the latter is smaller, cheaper, and intended for home use.

How long does it take to charge an electric vehicle on Level II? Again, it depends on the car and its battery size. For example, a Chevy Bolt EV can charge from empty to full in about nine hours on a Level II charger, while a Tesla Model S 75D with the same battery size can do it in about six hours.

DC Fast Charging (Level III)

The fastest way to charge an EV is with DC fast charging, which can juice up your car’s battery in a fraction of the time it takes with Level I or II charging. That’s because DC fast chargers send direct current (DC) directly to the battery, bypassing the onboard charger. This allows for much higher charging rates—up to 50kW or more.

As a result, you can charge an EV in as little as 30 minutes with DC fast charging. However, this convenience comes at a cost because DC fast chargers are much more expensive than Level I or II chargers. DC charging isn’t as widely available.


Factors that Impact EV Charging Time

Charging time for EVs varies due to several key factors. What’s your power source? How much power can your electric vehicle handle? How big is your EV’s battery? Let’s look at each of these important factors in more detail.

Power Source

The type of power source you’re using will impact how long it takes to charge your electric vehicle. If you use a standard 120-volt outlet (Level I), it will take much longer to charge your EV than if you’re using a 240-volt charger (Level II) or a direct current (DC) fast charger (Level III).

Onboard Charger

The onboard charger is the second biggest factor in determining how long it will take to charge your EV. Most EVs come with a Level II charger as standard equipment, but some higher-end models may come with a Level III charger. The faster the onboard charger, the shorter the charging time!

Battery Capacity

The size of your EV’s battery will also affect how long it takes to charge. A larger battery will take longer to charge than a smaller one, but it will also give you a longer range between charges.

Charging Rate

Finally, the charging rate will also impact how long it takes to charge your EV. Most electric vehicles can charge up to about 80% of their maximum capacity, but some newer models are capable of “fast charging” at up to 90% or even 100%!


What to Know About Rapid Charging

If you’re using a Level III charger (also known as a “rapid charger”), you should keep a few things in mind:

  1. Rapid charging can put a lot of strain on your EV’s battery, so it’s not something you should always do.
  2. Rapid charging can cause your EV’s battery to heat up, so keeping an eye on the temperature gauge is important.
  3. Rapid charging will reduce your EV’s range, so you’ll need to consider that when planning your next trip!
