How do I keep my ebike battery warm in the winter? (3 Ways)

Riding an electric bike in winter is an entertaining thing that is like an adventure.

But with the presence of the battery in the electric bike cold weather is one of the enemies of lithium batteries.

The maximum temperature at which your bicycle battery can be charged is 0°C and for discharging the internal temperature of the cells should not be less than -20°C.

That’s why in this post we will share with you three ways that you can use to keep your ebike battery warm in winter.

How do I keep my ebike battery warm in the winter?

As a general rule, the electric bike battery can be heated in the winter by using a battery cover and placing the battery inside the house, and also by the heat generated by the motor in the case of mid-drive

1- Use Battery Cover.

The use of a battery cover is one of the most important and first things that you should use to maintain an appropriate temperature for your electric bike battery.

The battery cover performs two important functions for the battery, first, to prevent cold air from entering the battery, and second, to increase the temperature resulting from the resistance that occurs inside the battery during use.

To be more precise, the cover can increase the internal temperature between 8 to 10 degrees, which is a very good percentage and will allow you to get a good performance level from the battery.

2-Keep battery inside the house.

The second way that will enable you to warm the electric bike battery is to keep the battery inside the house all the time when the ebike is not used.

The idea of this method is that the battery will gain room temperature and thus be ready
For use even if the weather outside the house is very cold.

The reason for this is the battery emits heat with use, which will help the battery maintain a high cell temperature even if the outside weather is cold.

3-Use the motor to warm the battery.

The method that I will explain here is the method that I do personally, which I use in case the weather is very cold and I want to use the bike quickly.

Note: This method is only valid in the case of the mid-drive motor.

  • First, charge the battery to 100%.
  • Put the bike above the ground.
  • Run the bike using the throttle for 5 minutes and you will notice that the heat of the motor is starting to transfer to the battery and it will increase the temperature of the battery.

Tips for Charging & Discharging in winter.

  • Before charging the battery, use a laser thermometer to measure the internal temperature.
  • Charge the battery before it reaches 0°C
  • Before leaving the house, make sure that the battery is 100% charged.
  • If the temperature is less than -20 C, make sure to cover the battery well during use.

What you should have in your ebike if you are living in a cold area?

If you live in a cold area and are thinking of buying an electric bike, in this section, we will share with you some tips that can help you get the best performance out of your electric bike.

1- Carbon frame.

Carbon does not conduct temperature as much as aluminum, so it is preferable if you live in a cold area to buy a carbon frame because, as we mentioned, it does not conduct heat as much as aluminum, and this will help you maintain the temperature of the motor and battery appropriately.

2- Internal Battery is better than external.

The second piece of advice for you is to try to choose a bike design where the battery is internal and not external (with the possibility of removing it) because the battery when it is internal, its exposure to cold air will be less, which will maintain a higher temperature inside the battery.

3- Fat Tire.

Having a fat tire on the bike is a must if you are riding your bike on snow because it helps increase the

contact area with the ground and also helps you to be more comfortable while riding the bike.

Does warming your ebike battery in winter will increase the range?

One of the frequently asked questions regarding the topic of the post is whether heating the battery will increase the range.

In fact, warming will not increase the range, but it will work to get you to the normal range of your battery without any effect from the cold weather.

It is known that cold reduces the flow of voltage in the battery, which causes the feeling that the performance of the battery decreases, but with warming the battery, the internal temperature of the battery will be suitable for the voltage to flow normally.


The electric bike battery can be warmed in winter by using the battery cover and placing it inside the house.

The internal temperature of the battery should be measured with a thermometer.

The battery should not be charged if the temperature reaches 0°C or use the battery if the temperature is -20°C
