How Fast Does EVgo Charge a Tesla? Debunking Myths & Maximizing Your Charging Speed

The short answer is: it depends, but EVgo chargers can deliver up to 350kW of power, potentially adding up to 200 miles of range in roughly 30 minutes for compatible Tesla models. However, achieving these optimal speeds requires understanding several factors, including your Tesla’s model, battery state of charge, charging station capabilities, and even the ambient temperature. Let’s delve deeper into the fascinating world of Tesla charging at EVgo stations!

Understanding Tesla Charging Speeds at EVgo Stations

While EVgo offers fast charging solutions, several crucial elements determine the actual charging speed your Tesla experiences. It’s not a simple plug-and-play scenario where every Tesla charges at the maximum advertised rate every time. Think of it like filling a glass: you can pour quickly at first, but as it fills, you need to slow down to avoid spillage. The same principle applies to EV charging.

Key Factors Influencing Charging Speed

• Tesla Model and Battery Capacity: Different Tesla models have different battery capacities and maximum charging rates. A Model 3 Long Range will generally charge faster than a standard Model 3, and a Model S Plaid can often accept a higher charge rate than either. Refer to your Tesla’s specifications for its maximum DC charging capacity.

• Battery State of Charge (SoC): This is arguably the most significant factor. Charging is fastest when your battery is nearly empty (around 20%). As your battery approaches full (80% or higher), the charging speed drastically slows down. This is a deliberate design feature to protect the battery’s longevity and prevent overheating. Think of it as the EV protecting itself.

• EVgo Charger Capabilities: EVgo stations offer varying charging speeds, typically ranging from 50kW to 350kW. While your Tesla might be capable of accepting a higher charge rate, it will only draw the maximum power offered by the specific EVgo charger you are using. Check the charger’s rating before plugging in.

• Ambient Temperature: Extreme temperatures, both hot and cold, can negatively impact battery performance and charging speed. In cold weather, your Tesla might use energy to warm the battery before charging, reducing the initial charge rate. Similarly, in very hot weather, the charging speed might be throttled to prevent overheating.

• Cable Adapter Usage: Since EVgo chargers primarily use CCS (Combined Charging System) connectors, Tesla owners need a CCS adapter. While these adapters are generally reliable, using one can sometimes slightly reduce the maximum achievable charging speed compared to a native Tesla Supercharger connection. Ensuring the adapter is properly connected and in good condition is crucial.

• Network Load and Charger Availability: Like any shared resource, charging speeds can be affected by network load. If multiple vehicles are charging at the same EVgo station, the available power may be distributed among them, resulting in slower charging for everyone.

Understanding Charging Curves

The charging curve is a graphical representation of how charging speed changes over time as your battery fills up. It’s not a linear process. As mentioned earlier, charging is fastest at lower states of charge and progressively slows down as the battery reaches higher levels. Understanding your Tesla’s charging curve can help you optimize your charging strategy and minimize your time spent at the charging station.

Example Scenarios and Estimated Charging Times

To give you a more concrete idea, consider these scenarios:

• Tesla Model 3 Long Range (20% SoC): Using a 350kW EVgo charger, you might see charging speeds exceeding 200kW initially, adding approximately 150-200 miles of range in 30 minutes.

• Tesla Model S Plaid (50% SoC): On a 150kW EVgo charger, you might see charging speeds around 100kW, adding roughly 75-100 miles of range in 30 minutes.

• Tesla Model Y (80% SoC): At a 50kW EVgo charger, the charging speed will likely be significantly reduced, possibly adding only 20-30 miles of range in 30 minutes. Charging beyond 80% at a public charger is usually not time-efficient.

These are just estimates, and the actual charging speed can vary depending on the factors outlined above. However, they provide a general sense of what to expect.

Frequently Asked Questions (FAQs) about EVgo and Tesla Charging

1. What type of connector does EVgo use? EVgo primarily uses CCS (Combined Charging System) connectors for fast charging. Tesla owners need a CCS adapter to use these chargers.

2. How do I find EVgo charging stations near me? You can use the EVgo app or the Tesla navigation system. The Tesla navigation system will typically show compatible CCS charging stations, including EVgo locations, when you plan a route.

3. How much does it cost to charge a Tesla at an EVgo station? EVgo’s pricing varies depending on the location and your membership plan. You can view the charging rate on the EVgo app or the charger’s screen before you plug in. They usually operate with a pay-per-kWh model.

4. Does EVgo offer membership plans? Yes, EVgo offers various membership plans that can reduce your charging costs. Explore their website or app for details and to determine which plan best suits your charging needs.

5. How do I pay for charging at an EVgo station? You can pay through the EVgo app using a credit card or debit card associated with your account. Some EVgo stations may also offer the option to pay directly at the charger using a credit card.

6. What if an EVgo charger is not working? Report the issue to EVgo customer support immediately through the EVgo app or by calling their helpline. They will typically troubleshoot the problem remotely or dispatch a technician if necessary. Document the problem by taking a photo of the screen, which shows an error.

7. Can I reserve an EVgo charger in advance? Currently, EVgo does not offer reservations for their chargers. Charging is on a first-come, first-served basis.

8. Is it safe to leave my Tesla unattended while charging at an EVgo station? Yes, it is generally safe to leave your Tesla unattended while charging. However, it’s always recommended to be aware of your surroundings and take necessary precautions to protect your vehicle.

9. How can I optimize my charging speed at an EVgo station? Preheat or precool your battery before arriving at the charging station, especially in extreme weather. Arrive with a low state of charge (around 20%). Disconnect from the charger once you reach your desired charge level (typically 80%) to free up the charger for other users.

10. Does EVgo use renewable energy? EVgo is committed to using renewable energy to power its charging network. They actively invest in renewable energy projects and strive to reduce their carbon footprint. Check EVgo’s website for details about their sustainability initiatives.

11. What is the difference between DC Fast Charging (DCFC) and Level 2 charging? DC Fast Charging (DCFC), like what EVgo offers, provides much faster charging speeds than Level 2 charging. DCFC uses high-voltage direct current, while Level 2 charging uses lower-voltage alternating current. Level 2 charging is typically used at home or at workplaces.

12. Are EVgo chargers compatible with all Tesla models? All Tesla models are technically compatible with EVgo chargers if they have a CCS adapter. Without the adapter, a Tesla cannot use an EVgo charger.

Charging your Tesla at an EVgo station can be a convenient and efficient way to keep your electric vehicle on the road. By understanding the factors that influence charging speed and following these tips, you can maximize your charging experience and get back to enjoying the open road in your Tesla. Remember to check the EVgo app for charger availability and pricing before you head out. Happy charging!
