Power Pack and Charging
5.2
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.
The BMS also monitors the power pack for a host of
predefined conditions, and then takes actions according to
those conditions.
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.
On-Board Power Pack Charger
Connect your power pack to the charger after each use.
Once recharged, disconnect from the AC power source.
Leaving your motorcycle unplugged between charges will
maximize the long-term health of the power pack. You
should use the supplied cable as it is designed for use with
your motorcycle’s electrical components. The power pack
must be charged within 24 hours if fully discharged. If you
don’t ride for an extended period of time (30 days or more),
you may want to plug the motorcycle into an AC power
source to charge it for a few hours prior to your next ride.
Note: For motorcycles with a ZF7.2 battery pack, using the
On-Board charger in conjunction with the Charge Tank is
not supported because it will exceed the max charging rate
for the battery pack. A fault code will display on the dash
and the motorcycle will not charge at the expected rate.
CAUTION: Only charge the Zero power pack with the Zero
charger. The on-board charger is located under the power
pack.
When charging the motorcycle’s power pack, the charger
can be left ON, even after the power pack is fully charged.
But unplugging your motorcycle after it is fully charged will
maximize long-term power pack health. If left connected,
there are two possible cases that can occur:
