About- Tesla battery drains in hot weather

Not only Tesla batteries but also all EV batteries can experience drain in hot weather. High temperatures always affect lithium-ion batteries to perform efficiently. See below how hot weather impact Tesla battery.

How does hot weather impact Tesla’s battery?

1. Accelerate chemical reaction

Extreme temperatures cause chemical reactions inside the battery that can lead it to self-discharge and faster degradation of the battery cells over time. 

2. Cause excessive resistance

Due to hot weather, resistance increased within battery cells which causes energy loss and reduces efficiency. It also limits the driving range of the vehicle. 

3. Pressure on the cooling system

The active thermal management system of Tesla helps to regulate the temperature of the battery pack to keep the battery temperature range tolerant. In order to maintain an optimal temperature system, the cooling system works harder. The pressure on the cooling system leads it to lose its overall efficiency.

4. Idle battery drain

When your vehicle doesn’t drive or stay parked, some Tesla battery power still keeps being used to regulate advanced features like remote monitoring, over-the-air update, screening alerts, and user software. So, the cooling system needs to run more to keep the battery from overheating which causes a higher rate of idle battery drain.

5. Abnormal charging behaviour

Charging in extreme weather can cause accelerated degradation. Also in a few cases, the on-boarding system of your vehicle prefers to secure charging limit to protect your battery from damage or explosion.

What to do to stop your Tesla battery drain in hot weather?

Reduce charging frequency: Limit your first charging frequency. Fast charging produces more heat and causes battery degradation. As you limit it, you take your first precaution.

Precondition your vehicle: Make sure to use your Tesla app to condition your vehicle before you get in and start driving. It will help to cool down both you and the chamber while your car still using grid power and plugged in by reducing the pressure.

Park your car in the shade: The best favor you will do to your car by parking it in the shade. Try to choose a shade or a covered area to protect your vehicle from direct sunlight. As much as you reduce the heat, you protect your Tesla battery from draining out. Make a parking room right outside of your home.

Oh, If you are outside, away from home, make sure you find a big tree to save your car battery.

Battery management and temperature control feature: Tesla updates their software frequently including battery optimizer and temperature controller features. Always keep your software up to date to manage your battery efficiently.

How to charge Tesla’s battery efficiently in hot weather?

  • Plan schedule charging on comparatively less temperature time
  • Avoid fast charging
  • Don’t charge the battery 100%. It helps the battery from taking over stress and saves heat-related degradation.
  • Use battery saver mode to reduce energy consumption
  • Use ‘ mode dog or pet mode’ during parking to conserve energy and reduce battery load.
  • Use smart charging by Tesla’s onboard charger. It will protect your battery from overheating.

All the above precautions and charging suggestions can help you save your Tesla battery drain in hot weather. Though Tesla’s battery is concerned to drain in hot weather, its active thermal management system has been inserted to minimize the risk caused by extreme temperatures and to keep the battery performance better and lifespan longevity.  

Remember, caring things always make it last long. Keep taking suggested precautions and save your Tesla’s battery from draining in hot weather. Happy Driving!
