Unleashing the Power: How Fast Can the 2018 Tesla Model S Really Charge?

Introduction

The 2018 Tesla Model S has been a game-changer in the electric vehicle (EV) world, offering luxury, performance, and—most importantly—supercharging convenience. For drivers, understanding how quickly this model charges at Tesla’s Supercharger stations is key to efficient, stress-free road trips. So, just how fast can the 2018 Model S charge? In this article, we’ll dive deep into the world of supercharging speeds, answer common questions, and reveal the secrets to optimizing every charge. Whether you’re a seasoned Tesla owner or considering a 2018 Model S for your next EV, this guide covers everything you need to know.

The Basics of Tesla Supercharging

What is Supercharging?

Supercharging is Tesla’s proprietary fast-charging solution, designed to get drivers back on the road quickly. It’s not just a charger—it’s a network of powerful stations that deliver DC power directly to your car’s battery. But unlike standard home charging, which can take hours, supercharging provides up to 170 miles of range in as little as 30 minutes.

Supercharging Stations and Locations

With over 40,000 Superchargers worldwide, Tesla has made it convenient for drivers to find charging stations. The 2018 Model S can connect to any Supercharger, but the speed it charges varies due to a few factors, which we’ll cover shortly.

How Fast Can the 2018 Model S Really Charge?

2018 Model S Supercharging Speed Stats

The 2018 Model S is equipped with Tesla’s 75 kWh and 100 kWh battery options, each with its own charging limitations. Here’s what you can expect for supercharging speeds:

• 75 kWh Battery: Max speed up to 120 kW
• 100 kWh Battery: Max speed up to 150 kW

Under optimal conditions, you can expect to regain about 170 miles of range within 30 minutes for the 100 kWh battery. However, the charging rate decreases as the battery fills up, meaning the first half-hour yields the fastest charge.

Factors That Affect Charging Speed

While the 2018 Model S has an impressive max speed, several factors influence actual charging times, including:

• Battery Level: Lower starting battery levels charge faster. Once the battery reaches 80%, charging speeds taper off to prevent overheating.
• Weather Conditions: Colder temperatures slow down charging. In winter, you may experience slower speeds as the battery warms up.
• Supercharger Version: Tesla Superchargers come in different generations, each with varying speeds. The V3 Superchargers (250 kW) are the fastest, but the 2018 Model S typically charges at V2 (150 kW) Superchargers due to compatibility.

FAQs on 2018 Model S Supercharging Speed

1. Can I Use a V3 Supercharger with the 2018 Model S?

• Answer: Yes, but with limitations. While V3 Superchargers support up to 250 kW, the 2018 Model S is capped at 150 kW, so you won’t get the full power of a V3 Supercharger. However, they still provide consistent, quick charging.

2. How Long Does It Take to Fully Charge at a Supercharger?

• Answer: For a nearly empty 100 kWh battery, a full charge may take 1-1.5 hours, though most drivers only charge to 80% to maximize time efficiency. Charging to 80% can take around 40-50 minutes, while a 50% charge is often reached in just 20-25 minutes.

3. Does Frequent Supercharging Affect Battery Health?

• Answer: Frequent supercharging can slightly reduce battery life over time. Tesla batteries are engineered for durability, but regular use of supercharging will add more stress to the cells than slow charging at home. To maximize battery lifespan, many owners use supercharging only on long trips.

4. How Much Does Supercharging Cost?

• Answer: Supercharging costs vary based on location and charging speed. As of 2023, Tesla typically charges between $0.25 and $0.35 per kWh. An 80% charge on a 100 kWh battery could cost around $20–$28, depending on regional rates.

Pro Tips for Optimizing 2018 Model S Supercharging Speed

1. Arrive with a Lower Battery Level

   • Arriving at a Supercharger with a battery around 10–20% allows for the highest charging speeds. Tesla’s charging curve is steepest when the battery is nearly empty, giving you more miles in a shorter period.

2. Preheat Your Battery in Cold Weather

   • Tesla’s “Battery Preconditioning” feature warms the battery as you approach a Supercharger, especially helpful in colder months. This automatic function maximizes the speed at which your battery can accept a charge upon arrival.

3. Avoid Charging to 100%

   • While it may be tempting, charging to 100% reduces long-term battery health and takes significantly longer. Most trips don’t require a full charge, so setting a charging limit to 80% will save you time and keep your battery healthier.

4. Consider Charging during Off-Peak Hours

   • Some Superchargers offer lower rates during off-peak hours. Charging overnight can not only save money but also ensure you avoid potential wait times at popular stations.

How the 2018 Model S Compares to Newer Models

Tesla’s advancements in charging speed have progressed rapidly, and newer models, like the 2021 Model S Plaid, now support peak supercharging rates of up to 250 kW. Compared to the 2018 Model S, newer models recharge about twice as fast on V3 Superchargers. However, many owners of the 2018 Model S report that the charging speed is still very manageable for most trips, especially when following charging tips for efficiency.

Conclusion

The 2018 Model S supercharging speed strikes an ideal balance between convenience and practicality. While newer Tesla models may charge faster, the 2018 Model S is still a powerful vehicle, providing a reliable and robust supercharging experience. By understanding the factors that impact charging speeds, optimizing your approach, and making smart charging choices, you can make every road trip with your 2018 Model S a smooth and enjoyable experience.
