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 6.33 ) 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.
