# How Many Kwh To Charge A Tesla (Explained)

A Tesla Model 3 Long Range takes about 5 hours to charge from 0-100% on a 240V Level 2 charger, and about 10 hours to charge on a 120V Level 1 charger. The exact charging time will vary depending on the battery size and the condition of the battery.

## How Many Kwh To Charge A Tesla

A Tesla Model 3 requires 30-45 kWh to charge from 0-100%. The exact amount of energy required depends on the battery size, temperature, and driving conditions.

## How Many kWh to Charge a Tesla

### The Basics

Teslas are powered by lithium-ion batteries, and the amount of energy required to charge them depends on a few factors, including the battery size, the state of charge (SOC), and the ambient temperature.

### Battery Size

The battery size of a Tesla is measured in kilowatt-hours (kWh), and the larger the battery, the more energy it can store. For example, the Tesla Model S has a battery capacity of 100 kWh, while the Tesla Model 3 has a battery capacity of 75 kWh.

### State of Charge

The state of charge (SOC) of a Tesla battery is expressed as a percentage, and it indicates how much energy is currently stored in the battery. When a Tesla is fully charged, the SOC is 100%. As the car is driven, the SOC decreases.

### Ambient Temperature

The ambient temperature can also affect the amount of energy required to charge a Tesla. When the temperature is cold, it takes longer to charge a Tesla battery because the battery’s chemistry is less efficient at lower temperatures.

### Calculating the Charging Time

To calculate the charging time for a Tesla, you need to know the battery size, the SOC, and the ambient temperature. You can use the following formula to estimate the charging time:

Charging time (hours) = Battery size (kWh) / Charging power (kW)

For example, if you have a Tesla Model S with a battery capacity of 100 kWh and you’re charging it at a rate of 10 kW, the charging time will be 10 hours.

### Charging Speeds

Tesla offers a variety of charging options, including Level 1, Level 2, and Level 3 chargers. Level 1 chargers provide a charging speed of 2-5 miles per hour, Level 2 chargers provide a charging speed of 5-20 miles per hour, and Level 3 chargers provide a charging speed of up to 200 miles per hour.

### Conclusion

The amount of energy required to charge a Tesla depends on a number of factors, including the battery size, the state of charge, and the ambient temperature. You can use the formula provided in this article to estimate the charging time for your Tesla.
