Opti-Range - Crosswave ED-3.2 EX Bedienungsanleitung

As chemical processes run more slowly when it is cold (and the
battery degrades with age) and viscosity of the electrolytes
used in the lithium cells greatly increases, internal resistance
of lithium-ion batteries also increases when it is cold, whereby
generated performance drops. In addition, the electrolytes used
can freeze at temperatures around -40°C.
The cell manufacturers specify working range to be 0 - 40°C.
18 - 25°C are optimum. Below 10°C, owing to the increased
internal resistance, performance may decrease to such an extent
that it is no longer sufficient for operating a Pedelec.
The electrolytes in the cells must not freeze, which corresponds
to a minimum temperature around -40°C. Cell manufacturers
recommend storing at 15°C with a battery charge of 60% - a
compromise between accelerated ageing and self-discharge.

Opti-Range

In order to make optimum use of the battery capacity, the riding
mode changes automatically to the next lower riding mode, as
the state of charge decreases. From mode 3 to 2, later from
mode 2 to 1. from E to drive off. This is based on the battery
voltage, thereby also protecting the cells against high load.
The next higher mode can only then be reached once the battery
has been recharged. In the case of e-bikes with a display,
OptiRange is displayed with "Battery low". The remaining capacity
is sufficient to power the bicycle lamps (LED illumination) for
approx. 2 hours. After the battery has been charged, all riding
modes can be used again.
On the display Opti Range is shown by the two flashing blue
LEDs 9 and 10.

Long-term trickle charging:
Lithium-ion batteries do not receive any long-time trickle
charging. Their self discharge is too low and the associated
charging devices therefore are not designed for it.
It is therefore not recommended to connect the battery to the
charging device continuously over a prolonged period of absence
especially in winter. The safety electronic circuit in the battery
will prevent any damage, but the charging device would be
working all the time.
Electrical devices should not be connected to the
mains over long periods without supervision. Hence,
you should pull out the power plug from the mains
socket during vacations or during long periods of
absence.
Tip:
If you do not use the Pedelec for long intervals, please recharge
the Lithium-ion battery once every 3 months. Pull out the fuse
from the battery during storage to rule out consumption of
electricity (very little) by the protective electronic circuit itself.
Of course, you must reinsert this fuse before charging again.
