SEVCON LCD Display
he SEVCON LCD display has following functions:
Battery State of Charge (SoC)
shown on bar graph at right of the screen and as percent % at top of the bar graph
(shown above as 78%) see IMPOR AN INFORMA ION on next page.
rip Distance raveled in miles in NN.N format (shown above as 1.7 mi.)
Odometer O AL Distance raveled in miles in NNNN.N format
(shown above as 1.7 mi.)
Vehicle Speed in MPH and KPH shown on semi elliptical bar graph
(shown as 0 MPH/KPH above)
Direction – Monitors the position of the “Direction Control Switch” and shows:
 D for Forward Drive (as shown above)
 N for Neutral
 R for Reverse
 indicates to CHECK the Electrolyte Level in Flooded raction Batteries
to reset the indicator hold the upper arrow button for 2 seconds [# ].

Battery Percent Charge Information on SEVCON Display
he Battery charge level indicates the relative state of charge of the raction Battery and
NO the remaining driving range of the vehicle.
Its algorithm is based on the PEAK raction Battery Pack Voltage, which in turn
calculates the APPROXIMA E charge of the raction Battery.
he 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).
his 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.
he 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.
he charge algorithm is designed to maximize the battery life and to prevent battery
damage by overcharge.
Initially when the vehicle is FIRS driven after delivery or whenever raction Battery is
serviced, the vehicle MUS be driven so that a discharge level of 69% or less is
achieved, and the raction Battery MUS 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 raction 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).
To proceed to a 2nd Screen push center arrow button [8 ] once.

performance of the vehicle.
It also displays the number of hours the vehicle was driven.

5th Screen
FAUL LOG
Log of all faults that have ever possibly occurred on the vehicle.
The first 8 of the faults on the screen are fault checks which are created at the time the vehicle is the first
programmed.
Any fault after that might be relevant. To check new faults you need to press the upper button [# ] twice and
the fault will appear 6th Screen).
6th Screen
It will give you the date and time the fault first appeared and the explanation what the fault means.

Note:
You will see a sequence fault if not started in neutral this code will clear as soon as you put the car in neutral.
The vehicle will possibly give you a cut back code. When the vehicle gets low on power it will automatically cut
back, this is a safety precaution to protect the motor and controller.
In many cases the fault is just a warning.
For example:
Thermal cut back just means the motor is too hot and will reduce the power to protect the motor.
Push the center arrow button [8 ] once, this will get you back to main screen
