How to Maintain the Electric Wheelchair in Winter?

Entering November also means that the winter of 2022 is slowly kicking in. Cold weather can shorten the journey of electric wheelchairs, and if you want them to have a long journey, the usual maintenance is indispensable. When the temperature is very low it affects the battery voltage, causing the battery to become less powerful and the power stored in the electric wheelchair battery to be reduced. A fully charged journey in winter will be roughly 5 km shorter than in summer. How should I keep the batteries of my electric wheelchair warm, and how can I extend the life of my electric wheelchair battery? Here are some solutions you may like to realize.

Frequent charging helps battery capacity stay healthy

Unlike charging a cell phone, to charge the battery of the electric wheelchair, it is better to charge the battery when it is half used. Make the battery in a "full state" for a long time, and charge it on the same day after use. If the battery is left idle for a few days and then charged, it is easy for the pole plate to sulphate and the capacity to drop. After charging is completed, it is best not to immediately cut off the power, and continue to charge for 1-2 hours to ensure that "full charge".

Periodic deep discharge

It is recommended that you perform a deep discharge every two months of use, i.e. long distance riding until the undervoltage indicator flashes and the power runs out, then recharge to restore the battery capacity. You will then be able to see if the current capacity level of the battery needs maintenance.

Do not store at a loss of power

Storage of batteries at a loss of power will seriously affect the service life, and the longer the battery is left idle, the more serious the damage to the battery. When the battery needs to be stored for a long time, it must be fully charged and replenished once a month.

Don't leave your power wheelchair outside

To prevent the battery from freezing, the battery of the electric wheelchair can be placed inside the house at a higher temperature when not in use, and should not be placed directly outdoors.

Attention to moisture 

When you encounter rain and snow, wipe it clean and dry before charging; in winter, there is more rain and snow, do not ride into deep water and deep snow to prevent the battery and motor from getting wet.
