OVERVIEW
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
Owne’r 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.
