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 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 drained to 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 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
and following the long-term storage guidelines (see
“
Parking and Long Term Storage”, on page 6.29) 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 that, while
charging, to prevent battery damage, the BMS will prevent
the charger from charging the battery at a temperature
below 32°F (0°C). Again, as long as the battery was
drained to ~60% state of charge and kept above 30% state
of charge through the winter at temperatures above -31°F
(-35°C), the battery will be safe from damage.
