Charging Tesla Model S

Everything Tesla Model S drivers need to know about charging an electric vehicle

The Tesla Model S, introduced in 2012, is the electric vehicle that changed the world’s perception of EVs. The large, luxury all-electric sedan combines long-range, sharp design, and near-instantaneous acceleration.

The two versions of the Model S offered in mid-2020 are the “Long-Range Plus,” providing 391 miles of all-electric range, and the crazy-fast “Performance” variant that clocks zero-to-60 mph in 2.3 seconds. The ability to thrill with acceleration like that brings down total range to 348 miles, which is still ample.

Either version of the Tesla Model S combines Maserati-like looks, BMW handling, and Mercedes-Benz comfort. The clincher is advanced Autopilot features and access to Tesla’s network of Superchargers.

Tesla Model S Charging & Range

Tesla’s powertrain and charging technology are all about pushing the boundaries of efficiency. Keep in mind that Tesla continually modifies the specs of its cars, so exact numbers for a model can be hard to pin down. The company updates its software all the time and deploys those changes to vehicles via over-the-air updates.

Tesla previously used numbers in the Model S’s trim name—like 100D or 75D to designate a 100- or 75-kilowatt-hour battery pack. Those 2019 models earned EPA range ratings of 259 and 335 miles, respectively. In 2020, the numbers are gone from the name, but the ranges are longer. Drivers have two choices: the 391-mile Long-Range Plus and the 349-mile Performance.

Thankfully, the charging rates (which are more dependent on hardware) are relatively fixed. When you’re in your garage using an at-home charging station, the onboard 11.5-kW charger adds about 30 to 35 miles of range every hour from a 48-amp Tesla charger like the JuiceBox 48. Now that's a powerful Tesla Model S charger for any Model S owner!

Level 3 DC fast charging: Tesla Supercharger

Charging the Tesla Model S on a road trip via a Supercharger can add as much as 170 miles of range in just 30 minutes. But the V3 version of the Tesla Supercharger ups the power output from about 120 kilowatts to 200 kW. The new and improved Superchargers, which launched in 2019 and continue to roll out, speed things up by 25 percent. Of course, range and charging depend on many factorsfrom the car's battery capacity to the charging speed of the onboard charger, and moreso “your mileage may vary.”

JuiceBox Benefits for Tesla Model S Drivers

High power vehicle charging options

The JuiceBox 48 (10 kW) provides the power you need to quickly charge your plug-in vehicle.

Standard 240V outlet

Tesla Model S and all other EVs can easily use the same fast charger outlet—just use the J1772 adapter that Tesla provides with its cars.

Reduce power, if your circuitry is limited

With a JuiceBox charging station, you can de-rate the power for home charging when a circuit breaker has limited capacity. You can also share electric car loads across multiple JuiceBox stations

Charge using more renewable energy

With JuiceNet Green, all U.S. Tesla Model X drivers can optimize charging for when renewables are high and electricity costs are low.

Tesla Model S Customer JuiceBox Reviews

  • 5 out of 5 stars: Works great, and customer service is also great

    I love the session reporting available in the JuiceBox, where I can see exactly how many kWh went into the car and the graph showing the flow of energy over time.

    I love that this JuiceBox has the J1772 plug, so it works with my LEAF, and I can put on the Tesla adapter. If I were to install a Tesla Wall Charger, I wouldn’t be able to also charge my Leaf. Also, this one device aggregates my electricity consumption of both electric cars into one report.

  • 5 out of 5 stars: Easy installation and network integration.
    I installed JuiceBox Pro this past weekend to provide 240v charging for both of our EVs (Bolt and Tesla). So far, so good. The dashboard is great for looking at history. I use the iPhone app and like the ability to charge on demand when needed. Setup through our network was easy and straightforward...Great purchase.

  • 5 out of 5 stars: Very solid, great quality, easy to install. Liked it so much, I bought another!
    I love me some JuiceBox! So much so that I bought two of them...We’ve been using them for 4 or 5 months and have had zero issues with them. Very happy with this purchase, and would happily buy another if needed.
