Ford Ranger EV. Electric Manual - part 17

LESSON 2: VEHICLE OPERATION

2-3

•

The instrument cluster has several new gauges and warning lamps

(covered later in this lesson).

•

When the driver key is turned to the START position, there is no

starter motor noise (although the vehicle is activated).

•

The Electric Ranger “creeps” forward like a gasoline-powered

vehicle with an automatic transmission that is in gear (after the

vehicle is “started” and the key remains in the ON position foot

off brake).

•

During deceleration, a higher drag is felt due to the regenerative

braking system (covered later in this lesson).

INSTRUMENT CLUSTER GAUGES

Battery State of Charge Gauge

•

The Battery State of Charge Gauge is the equivalent of the fuel

gauge on a gasoline-powered vehicle.

– F is indicated when the traction battery is fully charged.

– E is indicated when the traction battery is discharged to the point

where additional operation will reduce traction battery life.

•

The BCM monitors the percent of charge of each battery module

and calculates the average state of charge of the traction battery.

•

The BCM sends battery state of charge information to the IAA

through the J1850 (SCP) network.

•

The IAA uses the Battery State of Charge Gauge to indicate the

traction battery state of charge.

Battery State of Charge Gauge Inputs

NOTE: The POWER LIMIT and Low Fuel Warning Lamps flash

when the gauge reads empty. Vehicle performance will be extremely

limited at this point; the driver must pull over off the road (to the

shoulder) as quickly and safely as possible.

ECON (Economy) Gauge

•

The Economy Gauge not only shows the driver that his/her actions

affect vehicle range, but that driving more economically can

increase the vehicle range.

•

The gauge reading reflects:

– drivetrain power usage.

– vehicle speed.

– climate control usage.

– regeneration effects.

•

The needle will move toward the plus (+) sign (green band) when

the driver minimizes power usage or puts power back into the

vehicle.

•

The needle will move toward the minus (-) sign (yellow band)

when the driver accelerates quickly or turns on loads that reduce

vehicle range.

•

The IAA monitors several inputs and uses this information to

control the ECON Gauge.
