RIESE & MULLER load - E-bikes in Cold Weather Range

68
The electrical components of our E-bikes are
designed to operate down to a temperature
-10 °C with no problems. You just need to be
aware of a few things regarding using bat
-
teries in cold weather.
The energy content of a battery is always
listed at a certain temperature. In this case it
is stated at room temperature (23 °C). At this
temperature and above you can use 100 % of
the stated capacity of your battery.
In cold weather, the internal resistance
increases causing the energy content of your
battery to drop. You’ll notice a shorter range
on E-bikes in the winter. This is a normal
physical process and does not indicate errors
or defects. If you use your battery again
when it gets warmer, you can again use the
battery’s full energy content.
At temperatures of 10 °C this eect is very
low with the loss being in the single digits
and you will hardly notice the reduction.
With further decreasing temperatures, this
eect increases disproportionately.
In the extreme case of -10 °C you will only be
able to use approximately 70 % of the stated
battery capacity.
On cold days we recommend you store/
charge the battery overnight at room
temperature and then install the battery
on the bike just before driving o. It is also
important to draw some current from the
battery by using the motor support because
the drawing of energy warms the battery.
This should allow you to achieve the optimal
range of your E-bike.
It’s also a good idea to plan a shorter route in
the winter or use a lower level of support so
you are not surprised by a dead battery.
TIP!
Instruction for wintering your E-Bike:
charge the battery until 60 % of it’s
capacity. Recharge it every three
months until 60 % of it’s capacity.

DANGER!
Please note that condensation
can occur at the battery after
a sudden temperature change
from warm to cold. Avoid this
by charging and storing the bat-
tery at the same place. Use the
original charger only to avoid
the risk of re.
