E-bike battery in winter - This is what you should pay attention to

As nice and relaxing as riding an e-bike is, most cyclists store their bikes in winter. There are a few things to keep in mind, especially when it comes to e-bikes and their batteries, as incorrect storage in winter can cause considerable damage to the battery. For this reason, in this article we will give you valuable tips to ensure that your e-bike battery continues to provide you with enough energy next spring.

What options are there to protect your e-bike battery in winter?

The performance and lifespan of e-bike batteries is significantly affected by cold temperatures in winter. The low temperatures ensure that the chemical processes inside the e-bike batteries are slowed down. Here you will find various options and tips to protect your e-bike battery in the best possible way in winter.

How to protect your e-bike battery in winter:

  • In the cold season, a battery level of around 30-60 percent is recommended. This applies to both regular use and storage in the house.
  • You should avoid extremely cold and extremely warm temperatures when storing your e-bike battery.
  • Insulating covers around the e-bike battery help prevent the cold from getting to the battery.
  • Pay attention to the charging information that corresponds to the manufacturer’s instructions.

With these measures you can get your e-bike battery safely through the winter. Many more tips and tricks follow in the following sections.

Does the range of an e-bike battery change in winter?

Most e-bike batteries use so-called lithium-ion batteries, whose performance decreases in cold weather. The physical conditions of your e-bike battery ensure that the chemical processes inside the battery are slowed down in winter. As a result, the range of your e-bike battery also decreases in winter or in cold temperatures.

The following aspects ensure that the range of your e-bike battery can be reduced in winter:

  • Slowing down the chemical reaction in the lithium-ion battery
    Reduction in actual loading capacity.
  • The battery can store less energy when it is cold.
  • Reduced charging efficiency in winter
  • Increased energy consumption when driving in the snow, for example

In order to keep a reduction in the e-bike battery range in frost as low as possible, it is advisable to warm up the e-bike battery before a ride or to store the bike at moderate temperatures. Correct charging cycles according to the manufacturer's specifications also contribute to an improved range.

Overwintering your e-bike battery - With these tips you can store your e-bike battery over the winter

When storing your e-bike battery, you can do a lot of things wrong in winter and significantly worsen the lifespan and functionality of your battery. However, with our tips on this topic, you can easily get your e-bike battery through the winter without any problems.

Where should an e-bike battery be stored when it is frosty?

In order to best maintain the performance and lifespan of an e-bike battery, you should definitely store the e-bike battery correctly when it is frosty. In the following section we will give you numerous tips and recommendations for winter storage of e-bike batteries:

  • High temperature fluctuations are not useful. Make sure to keep the temperature differences as low as possible when storing the e-bike battery to prevent the formation of condensation and thus corrosion. In general, the battery should be stored in a room with low humidity.
  • Fully charged or discharged batteries age faster in the cold. A charging level of 30-60% is recommended.
  • E-bike batteries should ideally be stored at temperatures between 10° and 20°.
  • A neoprene cover or an insulation container for the battery can help keep the temperature level constant.
  • Be sure to store your e-bike battery in a dry place.
  • Charging a battery at extremely low temperatures is not recommended.
  • The e-bike battery should be stored clean and dry .
  • Store your battery away from flammable materials.

Most e-bike batteries are made from lithium-ion batteries, but the specifications of each manufacturer can vary. Please always pay attention to the manufacturer's instructions for optimal storage and handling of your e-bike battery.

Should I store my e-bike battery in a full or empty state in winter?

You should not store your e-bike battery in a fully charged or discharged state in winter. For optimal storage, a charge level between 30% and 60% is recommended. The reasons for this are as follows:

  • This battery level is sufficient for short and spontaneous trips.
  • At this battery level, the load on the battery cells is lowest. This way your battery will not be damaged.
  • E-bike batteries self-discharge over time. At this battery level you have enough buffer to avoid deep discharge. In addition, the rate of self-discharge decreases significantly at this battery level.

It is advisable to check the battery level regularly during winter storage.

What harms an e-bike battery in cold winter temperatures?

If the e-bike battery is used or stored incorrectly in winter, it can suffer significant damage. Here you will find some of the most common mistakes regarding e-bike batteries in winter:

  • Storage of the e-bike battery at temperatures below 10°Storing the e-bike battery in a fully charged or uncharged state
  • Rapid temperature changes (e.g. from a 20° warm house directly outside when temperatures are below zero)
  • Charging the e-bike battery in very cold temperatures
