Cold and Hot Weather Considerations
Cold Weather Operation
Operation of the motorcycle in cold temperatures has no
permanent impact on its battery pack/cells; however, the
rider may see a reduction in range due to the effect cold
temperature has on the amount of energy the pack/cells
can release. The colder the weather, the greater the effect;
so that, as compared to operation in 80°F (27°C) ambient,
at 30°F (-1°C) ambient the rider could experience a
temporary reduction in range of up to 30%.
In extreme cold weather the motorcycle may also
experience a temporary reduction in power and,
correspondingly, achieved top speed.
It is not recommended that the motorcycle be ridden while
its battery temperature is below 23°F (-5°C). If it is, its
battery needs to be put on the charger at a temperature
above 32°F (0°C) as soon as the ride is concluded. It is
worth noting that the Battery Management System (BMS)
will not allow the battery to be discharged below -22°F
(-30°C), which is the absolute lowest discharge
temperature prescribed by the cell manufacturer.
Storage of the motorcycle for the winter in a non-heated
garage is acceptable, as long as:
1. the coldest temperature in the garage does not fall
below -31°F (-35°C)
2. the battery is left on the charger continuously
3. the battery is initially topped off at a temperature above
32°F(0°C)
Storage temperatures below -31°F (-35°C) may result in
accelerated permanent decay of the battery performance,
and hence it is not recommended. Above this temperature,
working as a system with the BMS, the charger will ensure
the battery survives winter storage with no permanent
damage, even if the temperatures dip well below freezing
for weeks at a time.
Note: To prevent battery damage, the BMS will prevent the
charger from charging the battery at a temperature below
32°F (0°C). As long as the battery was initially topped off
by the charger above 32°F (0°C) and remains on the
charger through the winter at temperatures above -31°F
(-35°C), the system will guard the battery from damage.
