Tesla Model 3 Charging Time - A Complete Guide

The latest iteration of the Model 3 comes in three trims: Long Range Rear Wheel Drive (which is now the base model following the dropping of the Standard Range trim), Long Range All-Wheel Drive, and Performance. The Long Range trims offer 363 and 346 miles of driving range per charge, respectively, while the Performance has 296 miles of driving range per charge. The decision to kill the Standard Range model is linked to the Biden administration's new tariffs on Chinese EVs and Chinese-sourced components. This meant higher prices on Lithium Iron Phosphate (LFP) batteries, which would've prompted Tesla to hike the cost of the base Model 3 while retaining its capabilities.

If you're new to Tesla or just curious about how the trim levels affect charging times, read on.

Understanding Electric Vehicle Charging

Tesla models, like all electric cars, support three levels of charging:

1. Level 1 Charging (120V):

   • This is the slowest charging method and involves plugging your Tesla into a standard household outlet. It adds approximately 3-4 miles of range per hour of charging. For a full charge, this method may take 3-4 days, which may be good enough to use to charge overnight. While it’s not ideal for daily use, Level 1 charging can be useful in emergencies or if faster options aren’t available.

2. Level 2 Charging (240V):

   • Level 2 type chargers are the most practical and common for Tesla owners. These chargers can be installed at home or found in public locations such as workplaces or shopping centers. With a Tesla Wall Connector or similar 240V setup, you can add 30-44 miles of range per hour, completing a full charge in about 8-10 hours. This method strikes the right balance between speed and cost.

3. Level 3 Charging (DC Fast Charging):

   • The proprietary Tesla Superchargers fall under this category and offer the fastest charging speeds. Using DC Fast Charging a Model 3 can charge up to 80% in as little as 15-20 minutes with a V3 Supercharger Station (250 kW). This translates to up to 200 miles of range, depending on factors like battery state and temperature, which is ideal for long-distance travel or when time is of the essence.

Key Influencing Factors

Several factors impact how quickly your Tesla charges:

• Battery Size: Larger batteries take longer to charge but can add significant range in one session.

• State of Charge (SOC): Charging from a lower SOC takes longer than topping up a partially charged battery.

• Charger Power Output: The type and power of the charging station directly affect charger speed.

• External Conditions: Temperature plays a significant role. Extremely cold or hot weather can slow down charging or affect battery health.

How Long Does It Take To Charge An Electric Vehicle?

The duration required to fully charge an electric vehicle mainly depends on two factors: the amount of charge needed (kWh) and the charging station's power output (kW). Dividing the required charge by the charger’s power output provides an estimate of the time needed for a full charge of an electric car.

Calculation for EV Charging Time

To estimate your charging time, use the following formula:

Charge needed (kWh) / Charger power (kW) = Hours of charging time

Example Calculation

For a Tesla Model 3 with an 80 kWh battery:

• Starting battery level: 20%

• Target battery level: 80%

1. Calculate charge needed:

   • 80% – 20% = 60%

   • 80 kWh x 0.6 = 48 kWh required

2. Determine charging time:

   • Using a Level 2 charger with 7.68 kW output:

   • 48 kWh / 7.68 kW = 6.25 hours

Calculating Model 3 Charging Times

Model 3 Rear-Wheel Drive:

• Battery Size: 57.5 kWh

  • Example Charging Scenario: Charging from 20% to 80%.

    • Charge needed: 80% − 20% = 60%

    • Energy required: 57.5 kWh × 0.6 = 34.5 kWh

  • Charging Time (Level 2, 7.68 kW output):

    Time = 34.5 kWh / 7.68 kW ≈ 4.5 hours

Model 3 Long Range or Performance:

• Battery Size: 75 kWh

  • Example Charging Scenario: Charging from 10% to 90%.

    • Charge needed: 90% − 10% = 80%

    • Energy required: 75 kWh × 0.8 = 60 kWh

  • Charging Time (Level 2, 7.68 kW output):

    Time = 60 kWh / 7.68 kW ≈ 7.8 hours
