Cold and Hot Weather Considerations
Cold Weather
Cold weather operation of the motorcycle has no permanent
impact on its power 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
power pack 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 power
pack to be discharged below -4°F (-20°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 -4°F
(-20°C).
2. the battery has a ~60% state of charge prior to storage and
you check its state of charge at least monthly and charge it
back up to 60% if it has dropped below 30%
3. the power pack is initially topped off at a temperature above
32°F (0°C).
Storage temperatures below -4°F (-20°C) may result in
accelerated permanent decay of the power pack performance,
and hence it is not recommended. Above this temperature and
following the long term storage guidelines (see “Parking and
Long Term Storage”, on page 6.27) will ensure the power pack
survives winter storage with no permanent damage, even if the
temperatures dip well below freezing for weeks at a time.
Note: When charging, to prevent battery damage, the BMS will
prevent the charger from charging the power pack at a
temperature below 32°F (0°C). As long as the power pack is
maintained above 30% state of charge through the winter at
temperatures above -4°F (-20°C), the power pack will be safe
from damage.
