What’s the Best Amperage to Charge Tesla? (To Prevent Battery Degradation)

Electric vehicles, particularly Tesla cars, have revolutionized the automotive industry by offering a sustainable and eco-friendly alternative to traditional gasoline-powered vehicles.

As Tesla owners navigate the world of electric vehicle charging, one crucial decision they face is determining the best charging amperage for their vehicles.

This article delves into the factors that influence this decision and provides guidance on selecting the optimal charging amperage for your Tesla.

Understanding Tesla Charging Amperage

Tesla vehicles are equipped with onboard chargers that allow them to receive power from various charging sources. The charging amperage, measured in amperes (A), determines the rate at which electricity flows into the vehicle’s battery.

Higher amperage translates to faster charging times, but it’s essential to strike a balance between speed and the health of your battery.

Available Charging Options

Tesla owners typically have access to various charging options, including Level 1 (120V), Level 2 (240V), and DC fast charging. The charging amperage varies across these options, influencing the time it takes to charge the vehicle.

Level 1 Charging (120V):

  • This is the standard household outlet that provides the lowest charging amperage.
  • Tesla vehicles charging at Level 1 draw around 12A, resulting in slower charging rates.
  • Level 1 charging is convenient for overnight charging at home but may not be ideal for quick top-ups.

Level 2 Charging (240V):

  • Level 2 charging offers higher amperage, typically ranging from 16A to 80A.
  • Tesla vehicles can charge at 32A or 48A, depending on the charging equipment.
  • This option is commonly found at home charging stations, workplaces, and public charging stations.

DC Fast Charging:

  • DC fast charging is available at Tesla Supercharger stations and other high-power charging networks.
  • Tesla Superchargers can deliver amperages exceeding 100A, allowing for rapid charging.
  • This option is suitable for long-distance travel and quick recharging stops.

Factors Influencing Charging Amperage

Battery Health:

  • Charging at lower amperages is generally gentler on the battery, promoting longevity.
  • While Tesla batteries are designed to handle a variety of charging speeds, prolonged use of high amperage may contribute to faster degradation.

Charging Location:

  • Home chargers and workplace chargers often operate at Level 2, providing a balance between charging speed and convenience.
  • When using public charging stations, the available amperage may vary, influencing your charging strategy.

Charging Time:

  • The urgency of your charging needs plays a significant role in selecting the amperage.
  • Level 2 chargers with higher amperage are preferred for quicker top-ups, especially when time is a crucial factor.

Optimal Charging Amperage for Different Scenarios

Daily Charging at Home:

  • For daily charging needs, a moderate amperage of 32A is often sufficient for overnight charging.
  • This allows for a balance between convenience and battery health.

Long-Distance Travel:

  • When embarking on a road trip, utilizing Tesla Superchargers with high amperage ensures rapid charging stops.
  • DC fast charging minimizes travel downtime, making it ideal for covering long distances.

Workplace Charging:

  • Workplace chargers commonly operate at Level 2 with varying amperage.
  • Select an amperage that aligns with your work hours, ensuring the vehicle is adequately charged during the day.

Setting Your Tesla’s Charging Amperage

Tesla vehicles provide users with the flexibility to adjust the charging amperage based on their preferences. This can be configured through the vehicle’s touchscreen display or the Tesla mobile app.

  1. Navigate to Charging Settings:
    • Access your Tesla’s charging settings through the central touchscreen or the mobile app.
  2. Adjust Maximum Amperage:
    • Set your preferred charging amperage based on the charging scenario and your specific requirements.
    • Keep in mind that higher amperage may necessitate appropriate charging equipment.
  3. Scheduled Charging:
    • Utilize the scheduled charging feature to program your Tesla to charge during specific hours, leveraging lower electricity rates or ensuring a fully charged vehicle before your daily commute.


Choosing the best charging amperage for your Tesla involves considering various factors, including your charging location, daily routine, and the urgency of your charging needs. Striking a balance between faster charging and battery health is key to maximizing your electric driving experience.

Whether you opt for Level 1 charging at home, Level 2 charging at work, or the lightning-fast DC fast charging during road trips, understanding the charging amperage and tailoring it to your specific requirements ensures an efficient and sustainable electric driving experience with your Tesla
