General Operation
4.6
The power pack must be charged within 24 hours if fully
discharged, and charged within 90 days if stored fully
charged. Zero recommends you plug in your Zero
motorcycle after 90 days, even if fully charged. Please
leave your Zero motorcycle plugged in whenever possible.
Battery Management System (BMS)
Every power pack contains a Battery Management System
(BMS) which monitors the condition of the cells, and
optimizes the charging process to provide the
highest-performance, longest-range, and longest life for
the power pack.
The BMS safeguards the power pack by means of safety
interlocks. These interlocks turn off or control certain
operations that could damage the power pack. See
“Safety
Interlocks”, on page 6.16 for more information.
The BMS also monitors the power pack for a host of
predefined conditions, and then takes actions according to
those conditions. See,
“Battery Management System”, on
page 6.9 and “Cold and Hot Weather Considerations”, on
page 6.15 for further information.
The BMS is sealed inside the power pack. As a rider, you
don’t need to think much about the BMS - it just silently
does its job as you charge, ride, and store your
motorcycle.
Add On Electrical Equipment
WARNING!
Do not add electrical components to your
motorcycle unless approved by an authorized Zero
Motorcycles dealer. Some add-on electrical components
can damage your motorcycle, prevent other components
from working as they should, and/or dramatically reduce
the range and/or life expectancy of the power pack.
Power Pack Charger
Keep your power pack connected to the charger when
your motorcycle is sitting in storage or if it will be sitting
unused for more than 90 days. The power pack must be
charged within 24 hours if fully discharged, and charged
within 90 days if stored fully charged. Zero recommends
you plug in your Zero motorcycle after 90 days, even if fully
charged. Please leave your Zero motorcycle plugged in
whenever possible.
CAUTION: Only charge the Zero power pack with the Zero
charger. The charger is located under the power pack.
