Stage 2
If the motor, power pack, or brushless motor
controller continues to heat up:
•
The power to the motor begins to drop off,
resulting in a noticeable reduction in available
torque. This provides tactile feedback to the rider
and also helps prevent the component from
heating further. As the component cools again,
full-power will be restored.
•
At this point it is strongly recommended that you
reduce your speed and consider finding a safe
area to exit the road.
•
You may still have time to back off the throttle to
reduce heat. This will restore full power to the
motor and eliminate the warning indicator.
•
You can continue to ride without performance
interruptions.
•
You should reduce speed - this will lower power
output and the motor temperature to eliminate the
flashing warning indicator.
Power Pack Full (High Power Pack-Voltage)
If the BMS detects that the power pack is already full,
it will disable further charging to prevent damage to
the power pack.
This is not an error-condition; it is the result of a
successful charging cycle. There is no self-test flash
code which reports this condition.
During an ordinary charging cycle, when the cells are
balanced, the charger (not the BMS) will sense that
the power pack is full and terminate the charging
cycle with a “green light.” The BMS does have a
redundant back-up mechanism to prevent
overcharging of the power pack. If the charger fails to
terminate a charging-cycle when the power pack is
full, the BMS will terminate charging itself to prevent
damage.
