How To Precondition A Tesla Battery | Preheating Ins and Outs

In today’s automotive industry, Teslas are among the most advanced. Due to the growth in the demand for electric vehicles, many automotive lovers are shifting to Tesla. However, some new Tesla users usually question how to preheat a Tesla battery.

It is possible to preheat a Tesla battery by using the Tesla mobile phone app. Too cold batteries do not provide full recovery power while driving due to their low temperature. The fast charger cannot charge a cold battery at the maximum speed when it is cold. 

In this article, you will further learn about the preconditioning of the Tesla battery. You will also learn whether the temperature affects the Tesla batteries or not. So, keep reading. 

What Is Tesla Battery Preconditioning?

Preconditioning from your Tesla app will raise the temperature of the battery to optimal levels. Only precondition your battery for 1 hour before driving on long trips; this will improve regen breaking and avoid range loss. Also, precondition your battery before supercharging to increase charging performance.

By preconditioning your Tesla’s battery, your battery will be able to charge at the correct temperature. In addition to preparing your Tesla for Supercharging, preconditioning is seen when charging your Tesla in bitterly cold weather. This can reduce the charging time by 25%.

Tesla batteries preheat under the following conditions:

  • Connect the charging cable and turn on range mode.
  • Connect the charging cable with range mode off.
  • Without the charging cable and range mode turned off.

There is no range mode on Model 3. Therefore, the battery is constantly being preheated when necessary.

Pro Tip:

If you’re used to preconditioning your car for the morning commute, you’re probably wishing that the car could precondition itself for the ride home. There only seems to be one menu option for the schedule itself: either in the car or on the Tesla app. However, if you look closely, you will see the option: “Schedule departure for this location”. So, if you’re at work and would like to precondition your car, you can set up a departure for the trip home. It will appear as if you’re overwriting the previous schedule, but it will save both morning and afternoon routines.

How Long Should You Precondition a Tesla Battery?

Precondition your Tesla battery for 10-20 minutes before Supercharging. Preheating the battery at home may take 45 minutes or more, depending on the surrounding temperature. If you precondition your battery for 5 minutes, it will also raise the cabin temperature.

Let the battery warm up before starting at higher states of charge to get the most out of your fast-charging sessions.


Does the Cold Affect Tesla Batteries?

Colder weather of 40°F- and extremely hot weather of 80°F+ can affect your Tesla batteries. The rated range of your Tesla will rarely pan out as advertised. In colder temperatures, it can take almost twice as long to charge your Tesla. Try to avoid open spaces where the wind can reduce temperatures even further.

The cold weather will reduce the efficiency of any vehicle, electric or gas-powered. When it comes to Teslas, the range quickly drops off. Battery temperature is an essential factor in maintaining the performance of an electric car. 

Every time you get in your Tesla, the battery will warm up and use a significant amount of energy. Combatting this problem requires some measures. 

Do Tesla’s Need to Warm Up?

Teslas do not have to be warmed up to drive or charge them. This does have many advantages when doing so. Warming up your Tesla battery before driving generally protects it from long-term range efficiency loss. Tesla does not advise warming up or preheating every time before driving.

It is best to start a fast-charging session with a warm battery for long-distance trips at lower charge levels. 

Whenever you aren’t using your Tesla, I would recommend leaving it plugged in. Rather than using your battery, this uses your charging system to keep the heat.

Is Tesla Good in Snow?

Because of the quick reaction of electric motors, electric vehicles do exceptionally well on difficult roads. In addition to their dual-motor, all-wheel-drive powertrain, some Teslas can handle ice and snow, thanks to their all-wheel-drive system that can switch torque to the most traction-seeking wheels. 

When it’s cold and icy outside, use your Tesla app’s defrosting feature to reduce ice and snow. Make sure that the surfaces of your drive aren’t frozen or covered before you start your journey. 

You can break the ice on door handles by bumping them with the end of your fist. You can restore automatic mirror fold by manually opening and closing your mirrors if they are frozen. Use the defrost feature in your Tesla app to melt ice on your windows.

Does Tesla Use a Battery When Parked?

Because of the smart preconditioning setting on Tesla batteries, they lose their charge when parked. A smart preconditioning system will heat your cabin while turning on the battery heater. Although you are not driving your Tesla, these devices consume battery power. 

I recommend that you keep your Tesla plugged in as much as possible when it isn’t in use. This uses your charging system, rather than your battery, to keep the heat.

What Is Tesla Chill Mode?

You probably already know that the electric motors in Teslas are incredibly powerful and deliver instant torque as well as insane acceleration. 

Tesla’s zero-to-60-second time varies from model to model, but frankly, all of their products, including the S, X, and Model 3, are very fast vehicles at all levels of performance. 

For passengers in Tesla, acceleration can be so rapid that it may be alarming. Additionally, the incredible acceleration power also causes you to become impatient behind slow drivers if you tend toward road rage. 

By default, the car’s accelerometer decreases when you step on the pedal in “Chill mode.” Suddenly the car rides much more like a fully-loaded supercar and not quite like a regular fast sedan. 

If you’re driving alone, you can keep your acceleration at a reasonable level when talking to your friends or driving around your family without frightening them to death.

Teslas aren’t made slower by chill acceleration. A Tesla Model 3 Performance can still reach zero to 60 mph in 6.6 seconds instead of less than 4 seconds with the chill mode on. 

As a rule of thumb, if you compare a Tesla’s zero to 60 times with chill mode, you will expect it to be approximately double that time. Unlike range mode, the chill mode does not increase your range. 

It is not a requirement, but it’s possible. If you combine chill mode with hypermiling, your range will increase as you improve your driving efficiency. 

When driving on ice, snow, or rain, you may find the chill mode very helpful. When you press the accelerator pedal, you don’t have to worry about your wheels slipping out.

How to Take Tesla off Chill Mode?

Tesla’s touch screen provides access to the ‘Chill Mode’ under the ‘Driving’ section. The driver can toggle between Standard Mode and Chill Mode, among other settings related to driving. By pressing the Chill Mode again, you can turn it off.

How to Rebalance Tesla Battery?

For the Tesla battery to rebalance, it is recommended to charge the vehicle to 90-100% and rest for at least 24 hours before using or charging it again. 

Once you reach a state of charge near 20%, you can drive the vehicle normally. For about 24 hours after that, don’t use or charge the vehicle again. Next, the charging and usage will resume normally. It is best to charge 80% daily.
