Battery Status Indicator
The battery status indicator (BSI) is shown on the
right side of the dash display main screen. This gauge
functions similar to a fuel gauge in an automobile. At
the top of the gauge, it shows the percentage remaining
in the battery.
The BSI is not an absolute gauge of power remaining
in the battery. The amount of available power is
relative to the amount of power required. As the power
requirements are increased, such as driving up a hill, the
relative available power in the battery is decreased. The
motor speed control system estimates the battery power
remaining by monitoring the current driving conditions.
There are 10 bars in the bargraph display, each bar
representing 10% of battery power.
At 10% estimated battery power remaining (last bar showing), a warning message will pop up at
the bottom of the display informing the driver of the low battery condition. It is important to drive to
a charging station as soon as possible.
If the estimated battery power remaining drops below empty, then the control system will reduce
the power to the motor in order to conserve energy. To avoid damage to the battery, the vehicle
should be immediately taken to a charging station.
Note: The BSI will only reset to full after a full charging cycle has completed. In addition, the BSI
will not reset to full unless the battery is discharged below 75% before starting the charge
cycle.
While coasting, the batteries are being charged through a process called regenerative
braking (regen). It is possible that the BSI could reset to full while in the regen braking mode.
Details regarding the regen braking mode can be found in the Vehicle Operation section.
