Display Panel - Battery State of Charge (SoC)
IMPORTANT INFORMATION
Battery Percent Charge Information on SEVCON Display
The Battery charge level indicates the relative state of charge of the Traction Battery and
NOT the remaining driving range of the vehicle.
Its algorithm is based on the PEAK Traction Battery Pack Voltage, which in turn
calculates the APPROXIMATE charge of the Traction Battery.
The indicator may not always show 100% when the vehicle is first turned on even if the
On-Board
Delta-Q
charger indicates 100% or full charge condition.
(Green LED ON – see
Charging Procedure
in
Owner Manual
for more detail).
This condition is not a defect as the computerized “smart”
Delta-Q
On-Board Charger
may under certain conditions stop the charging before achieving the maximum potential
voltage.
The ambient and battery temperatures are monitored by the charger and the charge cycle
is automatically terminated based on internal charge algorithm that is matched to the
specific type of Battery, which is used in your vehicle.
The charge algorithm is designed to maximize the battery life and to prevent battery
damage by overcharge.
Initially when the vehicle is FIRST driven after delivery or whenever Traction Battery is
serviced, the vehicle MUST be driven so that a discharge level of 69% or less is
achieved, and the Traction Battery MUST BE FULLY CHARGED thereafter, in order
for the State of Charge bar graph indicator in the
SEVCON
Display to self reset to
100% indication.
If the Traction Battery is not deeply discharged (to below 69%) the State of Charge will
generally not indicate more than 80% even if the On-Board
Delta-Q
Charger indicates
FULLY Charged condition.
For long battery service life, the vehicle should not be operated when the indicated
Charge Level is 20% or less, and need not to be re-charged if the Display Indication is
80% or more.

Display Screen – Other Functions
Main Screen
Main screen will display Direction, Speed and Battery Charge Level, it also displays Trip and Odometer
(total miles) mileage traveled.
If the low water battery symbol appears please check the water level in all batteries.
To clear the low water battery symbol push upper arrow button

2 times; this will clear the low
water level symbol.
NOTE:
The vehicle MUST be in neutral (N) when you first turn the key “ON”; thereafter you can select
forward (F) or reverse (R). The car will not move unless you start in neutral (N).
