Battery System Warnings

WARNING: THE TRACTION BATTERY CAN DELIVER

312 VOLTS OF DC POWER. IMPROPER HANDLING

OF THE TRACTION BATTERY CAN RESULT IN

INJURY OR FATALITY. ONLY AUTHORIZED

PERSONNEL TRAINED TO WORK WITH TRACTION

BATTERY COMPONENTS ARE PERMITTED TO

HANDLE THE BATTERIES.

WARNING: BATTERIES NORMALLY PRODUCE

EXPLOSIVE GASES WHICH CAN CAUSE PERSONAL

INJURY OR DEATH. DO NOT ALLOW FLAMES,

SPARKS OR LIGHTED SUBSTANCES TO COME NEAR

THE BATTERIES. WHEN CHARGING OR WORKING

NEAR THE BATTERIES, ALWAYS SHIELD YOUR

FACE AND PROTECT YOUR EYES. ALWAYS

PROVIDE VENTILATION.

WARNING: LEAD-ACID BATTERIES CONTAIN

SULFURIC ACID. AVOID CONTACT WITH SKIN,

EYES OR CLOTHING. ALSO, SHIELD YOUR EYES

WHEN WORKING NEAR BATTERIES TO PROTECT

AGAINST POSSIBLE SPLASHING OF THE ACID

SOLUTION. IN CASE OF ACID CONTACT WITH THE

SKIN OR EYES, FLUSH IMMEDIATELY WITH

WATER FOR A MINIMUM OF FIFTEEN MINUTES

AND GET PROMPT MEDICAL ATTENTION. IF ACID

IS SWALLOWED, DRINK LARGE QUANTITIES OF

MILK OR WATER, FOLLOWED BY MILK OF

MAGNESIA, A BEATEN EGG, OR VEGETABLE OIL.

CALL A PHYSICIAN IMMEDIATELY.

Traction Battery

Traction Battery

•

The traction battery is located underneath the vehicle between the

frame rails.

•

The traction battery consists of 39 8-volt lead-acid battery modules

stored in a supporting tray.

•

The supporting tray is constructed of an extremely strong non-

conductive composite material with bonded metal mounting

brackets.

– The tray is about 8 feet long and weighs almost 900 kg (2000 lb)

with battery modules and associated components in place.

– The supporting tray has a cover which is bolted on. There are

individual battery modules and other components contained

within the traction battery supporting tray.

•

The 39 battery modules are arranged in 2 levels, 12 on the upper

level and 27 on the lower level.

•

The battery modules are wired in series and produce 312 volts DC.

•

A battery control module is located in the upper level at the front of

the assembly.

– The battery control module is secured with Velcro

®

.

•

A contactor box is located in the upper level at the rear of the assembly.

– The contractor box is secured with Velcro

®

.

•

A cooling system and a (optional) heating system (for cold climate

areas) are used to maintain optimal temperature within the traction

battery.

Traction Battery Cooling System

Traction Battery Cooling System

•

The traction battery cooling system consists of:

– four temperature sensors.

– a two-speed fan.

– a battery control module.

•

The cooling fan is located in the center of the traction battery.

•

The cooling function is controlled by the battery control module

(BCM).

•

During charging, the cooling fan is used for ventilation and

cooling of the traction battery:

– For ventilation, the cooling fan operates at low speed all the

time.

– For cooling, the cooling fan operates at high speed based on the

temperature of the traction battery.

– For ventilation purposes, the cooling fan operates for 10 minutes

following the completion of the charge cycle.

•

During driving, the cooling fan is used for cooling the traction

battery:

– For cooling, the cooling fan operates at high speed based on the

temperature of the traction battery.

– Air is drawn in from the rear of the traction battery and exits

through the front.

NOTE: Be sure vent openings are clear of obstructions before

connecting charger.
