Das Bike in Herbst und Winter: Warum der E-Bike-Akku keine Kälte mag

Winter and autumn bring chilly mornings for cyclists, but electric bikes provide assistance with their pedelec motors. However, the e-bike's battery needs special attention, as it does not like cold temperatures. Overlooking this can reduce the battery's performance and lifespan, warns the test organization Dekra. Nevertheless, e-bike batteries are still suitable for winter use, provided they remain at operating temperature while in use.

The battery prefers room temperature, ideally between 10 and 20 degrees Celsius, as recommended by Dekra's bicycle expert Jochen Hof. Only when the battery reaches room temperature should it be recharged. Keeping the battery at the specified conditions when storing it indoors can help prolong its range. For e-bikes with integrated batteries, it is best to store them indoors under these conditions.

If an e-bike with an integrated battery must be left outdoors, cyclists can minimize the cold's impact by using thermoshields to protect the battery from cooling down. Alternatively, a bicycle shelter can provide additional protection for the entire bike. Avoid charging the battery when temperatures drop below 0 degrees Celsius, and recharge it promptly after a ride if it still retains some operating temperature.

Storing the battery in cold temperatures significantly affects its lifespan and capacity, so cyclists who primarily park their e-bikes outdoors should consider choosing a model with a removable battery.
