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 6.29 ) 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.
