How long does it take to charge an electric car?

We'll show you a little formula so you know how long it takes to charge your electric car depending on two factors.

There is no one type or time to charge an electric car. There are three speeds (or levels) that are differentiated:

Slow charging (Level 1): when it takes 5 to 8 hours to charge

Semi-quick charging (Level 2): when it takes an average of 1.5 to 3 hours to charge.

DC Fast Charging (Level 3): the car charges in about 15 minutes or less. Sometimes a different connector is used for this.

We must also keep in mind that vehicles have different charging modes, one faster (DC) and one slower (AC).

How does the calculator calculate how long to charge an electric vehicle?

The charging time for an electric car depends on different variables. 

The first thing you need to know is battery capacity. How do you find out the battery capacity of an electric car? Here in the calculator, by selecting the model you will immediately see information about the battery. You can check this information in the datasheet of your car. This data is presented in kWh (kilowatts per hour). For example, a car like the Chevrolet Bolt has a battery capacity of 65 kWh. If you want to know the characteristics and types of batteries that exist, experiment with selecting electric car models in the calculator.

Another piece of information we need to know is the battery charger capacity (EVSE) or charging intensity. This information is calculated by multiplying the voltage (in the U.S. it is 120 V or 240 V) by the charger's power, measured in amps. Generally, with electric chargers, you can already see the degree of power covered in kW, so you only need to multiply the battery capacity and power by 1000. The good news is that a calculator will do it for you here.

How Do I Calculate the Charging Time for an EV?

When calculating the charging time of an EV, there are several factors to consider. The optimal charging time for an EV is based on battery capacity, onboard charger power rating, and charging losses. Assuming that a power source is capable of maximizing chargers, this can be estimated in about 30 minutes. Then, the remaining charging time is based on those factors.

EV charging duration depends on a number of factors

The charging time of an EV can be as short as 20 minutes or as long as 12 hours, depending on various factors, including the battery pack size and state of charge. You may be wondering why the charging time of an EV is so different. Well, let's look at some of these factors and find out how they affect charging time. The best way to calculate the charging time of an EV is to compare its battery capacity to the charge time of a typical vehicle.

The charging time of an EV depends on several factors, including the size of the battery and the power of the charging station. However, fast EV charging is the most preferred method right now, with charging stations capable of 11kW to 22kW. As EV technology continues to improve, it is still unclear what factors affect the charging time of an EV. The time it takes to fully recharge an EV depends on many factors, including its speed of charging, the type of charger used, the location of the charging station, and a number of other variables.

Level 2 chargers deliver 25 miles (40 kilometers) of range

If you want to know how to calculate the charging time for your EV, you should know that a typical EV battery requires about an hour of power to reach its maximum capacity. However, if you want to know how long it will take your EV to charge to full capacity, there are several factors to consider. You should also know that EVs vary in the size and power of their batteries, so the exact charging time will depend on the model and battery size.

Charging times for electric cars vary, depending on the size of the battery, the charging method, the battery level, and the type of charger you use. The best way to figure out the charging time for your EV is to make a rough estimate on the EV's battery level and the type of charger you'll be using. If your battery is low or full, your charging time will be half of the expected total time. The reason for this is a built-in feature in EVs to extend battery life and avoid overcharging.

Simplified formula for calculating your electric car's charging rate:

Duration = Battery capacity (kWh) x 1000 / EVSE power (kW) x 1000

Or, for example, a car with a 65 kWh battery using a 6.5 kW charger would take this time to charge:

Duration = 65000/6500 = 10 hours.

Of course, a very rough calculation is shown. The Electric Vehicle Calculator, however, takes into account the 10% loss, and the individual limitations of the electric car's built-in charging unit. 

The most common way to charge an electric car is using a home charging station (wall connector) in a private garage with a NEMA 14-50 socket. Depending on the charger and different manufacturers, you can also get faster (Level 2) or slower charging (Level 1). If you choose one of the best charging stations, it will negotiate the maximum allowable power with the car without your involvement.

The fastest charging, on the other hand, is available at constant current charging station networks. Tesla has its connector but can use j1772 on the networks with an adapter.
