How Fast Does 16kw Charge A Tesla

A 16-kW charger will charge a Tesla from empty to full in about 5–6 hours. Depending on a few factors like the battery level of your Tesla, the ambient temperature, and the type of charger.

A 16-kW charger can add about 25 miles of range to a Tesla in an hour. However, the charging speed will be slower if the battery level of your Tesla is high or if the ambient temperature is cold.

In this article, we will discuss how long it takes to charge a Tesla with a 16kW charger, the factors that affect charging speed, the different types of Tesla chargers and their charging speeds, and provide you with tips for maximizing charging speed in Tesla. If you are ready, let’s dive in!

How Fast Does 16kW Charge A Tesla

The charging speed of a Tesla depends on several factors, including the type of charger, the battery size, and the state of charge. A 16kW destination charger is a type of Level 2 charger that can provide up to 16kW of power to a Tesla.

However, the actual charging rate depends on the onboard charger of the Tesla, which can be either 40 or 72 amps. A 40-amp onboard charger can receive up to 8.3 kW of power from a 16 kW destination charger, while a 72-amp onboard charger can receive up to 17 kW of power.

This means that a 16kW destination charger can add about 25 miles of range per hour to a Tesla with a 40-amp onboard charger, or about 55 miles of range per hour to a Tesla with a 72-amp onboard charger.

Another factor that affects the charging speed is the battery capacity of the Tesla. For example, the Tesla Model Y Performance has an 82 kWh battery, while the Model Y Long Range has a 75 kWh battery.

The Model Y Standard Range has a smaller battery of 57.5 kWh. The larger the battery, the longer it takes to charge it fully. To estimate the charging time from empty to full using a 16 kW destination charger, we can divide the battery capacity by the charging rate.

For example, a Model Y Performance with a 72-amp onboard charger would take about 82 / 17 = 4.8 hours to fully charge using a 16 kW destination charger. A Model Y Long Range with a 40-amp onboard charger would take about 75 / 8.3 = 9 hours to charge fully using a 16 kW destination charger.

However, these are just rough estimates that assume the battery is completely empty and no other factors affect the charging speed.

In reality, the charging speed varies depending on the state of charge and other conditions such as temperature, voltage, and current.

The charging speed is usually faster when the battery is low and slower when the battery is high. This is because Tesla uses a tapering algorithm that reduces the charging rate as the battery approaches full capacity to protect the battery’s health and longevity.

Therefore, it is not recommended to charge the battery to 100% unless necessary, as this can reduce the battery life and performance over time.

A more realistic estimate of charging time can be obtained by using the Tesla charging calculator, which allows you to input your model, battery size, state of charge, and type of charger to get an accurate estimate of charging time and cost for different scenarios.

Factors That Affect Tesla Charging Speed

1. Type of Charger

The type of charger has the biggest impact on charging speed. Level 2 chargers are slower than Level 3 chargers, and Tesla Superchargers are the fastest.

2. Onboard Charger

The Tesla Model S and Model X have a 40-amp onboard charger, while the Model 3 and Model Y have a 72-amp onboard charger. A higher-amp onboard charger can accept more power from a charger, which means faster charging speeds.

3. Battery Size

The larger the battery, the longer it takes to charge. For example, a Tesla Model 3 Long Range has a 75 kWh battery, while a Tesla Model 3 Standard Range Plus has a 50 kWh battery.

The Model 3 Long Range will take about 10 hours to charge from empty to full using a 16kW charger, while the Model 3 Standard Range Plus will take about 7 hours.

4. State of Charge (SOC)

The charging speed is usually faster when the battery is low and slower when the battery is high. This is because Tesla uses a tapering algorithm that reduces the charging rate as the battery approaches full capacity to protect the battery’s health and longevity.

5. Temperature

The charging speed is slower in cold weather than in warm weather. This is because the battery needs to warm up before it can charge at its maximum speed.

6. Voltage

The charging speed is slower with a lower voltage. This is because the battery can only accept a certain amount of power, and lower-voltage chargers can only provide less power.

7. Current

The charging speed is slower with a lower current. This is because the battery can only accept a certain amount of power, and lower-current chargers can only provide less power.

Tips for Maximizing Charging Speed in Tesla

Here are some tips for maximizing charging speed at Tesla:

  • Use a high-powered charger. Tesla Superchargers are the fastest chargers available for Tesla. They can charge a 75-kWh battery from empty to full in about 20–30 minutes.
  • Plug in your Tesla as soon as possible. The battery will charge faster when it is not fully depleted.
  • Use the correct charging cable. Tesla comes with a standard charging cable that can be plugged into a 120V outlet. However, this will only charge the battery at a very slow rate. For faster charging, you will need to use a 240V charging cable.
  • Avoid using accessories. Accessories that draw power from the battery, such as the heated seats or the air conditioning, will slow down the charging speed.
  • Charge your battery regularly and avoid letting it drop below 20% or above 90%. This can help maintain your battery’s health and capacity.
  • Reduce the weight and drag of your vehicle by removing unnecessary cargo, roof racks, or accessories. This can improve your efficiency and range, which means you need to charge less often.
  • Plan your trips and charging stops ahead of time using the navigation system or the mobile app. This can help you find the best route and the nearest Superchargers or other charging stations.
  • Keep your software up to date. Tesla regularly releases software updates that improve the charging performance of its vehicles. Make sure to keep your software up to date to get the fastest possible charging speeds.

Tesla Charging Rates Chart

It is important to note that these are just general charging rates. The actual charging speed may vary depending on the specific Tesla model and charger being used.

For example, a Tesla Model 3 with a 75 kWh battery will charge at a faster rate than a Tesla Model S with a 100 kWh battery. Additionally, the charging speed may be slower in cold weather or if the battery is already partially charged.

Conclusion

A 16-kW destination charger is a convenient way to charge your Tesla while you are parked at a hotel, restaurant, or shopping center. However, it is not the fastest way to charge your Tesla, as superchargers can deliver up to 250 kW of power and charge your battery up to 80% in less than 30 minutes.
