What to do if the electric bike's battery life decreases in winter?

With the popularity of electric bicycles, many people are gradually starting to use them as a daily means of transportation. However, some people may encounter the issue that electric bicycles usually cannot travel long distances in winter, causing certain inconvenience. Do you know what causes this? Today, this article will analyze the reasons for the shortened battery life of electric bicycles in winter.

The impact of batteries

The decrease in temperature will affect the performance of electric bicycle batteries, mainly because the chemical reactions inside the battery will be influenced by temperature. The chemical substances inside the electric bike battery will have different activities at different temperatures. When the temperature drops, the activity of the chemical substances will decrease, leading to a decrease in the battery's storage capacity and a reduction in the amount of stored energy. At the same time, the battery's discharge capacity will also be affected, resulting in a shorter driving range for the electric vehicle. Additionally, in cold environments, the viscosity of the battery's electrolyte increases and conductivity decreases, which will also affect the battery's charging and discharging performance. Furthermore, if the battery is exposed to low temperatures for a long time, it may cause certain damage to the battery's structure and performance, shortening the battery's lifespan. Therefore, when using electric bicycles in winter, attention should be paid to the maintenance and insulation of the battery to extend its lifespan and ensure its performance in cold environments.


Since low-temperature weather has such a great impact on electric bicycles, what measures can be taken to reduce the impact of low temperature weather on battery life?

  1. The charging temperature should be appropriate

    When it's cold, the battery may not be fully charged. At this time, we can adjust the charging environment temperature by placing the battery in an area with a moderate temperature. The optimal temperature is 25 °C, which allows the battery to be fully charged to 100% capacity. This way, the battery will not feel underpowered when used in the winter.

  2. Increase charging time

    One of the main reasons why the winter battery doesn't last long is that the battery charging time is not enough. In winter, battery charging efficiency decreases due to the low temperature. Therefore, you can extend the charging time appropriately, which can also maximize the battery's endurance. However, be careful not to extend it too long.

  3. Avoid charging after completely draining the battery

    Whether it is a new battery or an old battery, it is recommended that you try to avoid completely draining the battery before recharging. It is most reasonable to charge when the battery level is around 25% remaining.

  4. Regular charging

    If you do not have a long-term cycling demand, please try to ensure that you charge the battery at least once a month to avoid storing it in a discharged state and extend the battery's lifespan.

  5. Pay attention to accessory maintenance

    If you often use an electric bicycle, you will find that even a newly purchased electric bicycle will have a lot of dust or stains on the hub after frequent use. In rainy or snowy weather, the hub will also be washed, affecting the lubrication of the electric bicycle hub and making your riding more laborious. In addition, it is necessary to regularly check whether all parts of the electric bicycle are normal, such as tire pressure, brakes, bearings, gears, motors, etc., to ensure that the electric bicycle is in the best working condition.
