Smart Charging Modules (SCM)
Each pair of batteries is connected to a Smart Charging Module
(SCM). The SCMs control current flow to and from the
batteries based on commands from the Main Controller. The
SCM can be in one of three modes (not selectable by the
driver):

Charge Mode allows current to flow into the TriPace
batteries.
•
Discharge Mode allows current to flow out of the TriPace
batteries.
•
Null Mode prevents flow of current in either direction.
Control Circuits
Power Sources
All of the batteries onboard the truck, including the TriPace
system batteries, are a reservoir of electrical power. When the
truck is parked the TriPace system, and any other electrical
devices are in use, the power in this reservoir is being
consumed. The faster the power is consumed, the sooner the
power reservoir will be empty.
NOTE: Use of truck accessories such as lights, refrigerators,
TVs, etc. draws power from the batteries and will compete
with the climate control electrical demand of the TriPace
system. Heavy use of these devices and/or use of the optional
12 Vdc to 115 Vac Power Inverter will reduce the potential
run time of the TriPace system. In addition, high ambient
temperature will cause near continuous operation of the
TriPace air conditioning system. This increased electrical
demand will reduce the number of hours the system can
control cab temperature. In high ambient conditions the
driver should reduce the use of electrical accessories to a
minimum to extend air conditioning time.
The control circuits operate on 12 Vdc supplied by the system
batteries.

Unit Description
The TriPace power management technology makes the most
efficient use of available power. The TriPace system may draw
from the truck batteries and TriPace battery pack at same time.
There is a Current Sensor in the interconnect cable between the
TriPace batteries and truck batteries. It provides the Main
Controller with information to help manage power flow. A pair
of Smart Charging Modules (SCM) monitor and control power
flow to and from the TriPace batteries. The SCMs provide the
Main Controller with battery status information. The TriPace
system can draw as much as 100 amps during full air
conditioning demand.
Power for the TriPace system comes from the following three
sources. All system power is sent to a main fuse block in the
TriPace battery box.
TriPace Battery Box: The TriPace Battery Box is the
primary power source for the TriPace system.
Truck Batteries: The OEM truck battery bank is the
secondary power source for the TriPace system.
Shore Power Converter (option): The Shore Power
Converter is a 115 Vac to 12 Vdc power converter that provides
low voltage power to the system. The Converter will help
extend operation of the system before the batteries are depleted
when the truck is parked and plugged into 115 Vac external or
"Shore Power." During moderate ambient temperature
conditions with moderate air conditioning demand the
converter may support the system without draining the
batteries. During high ambient temperature conditions with
high air conditioning demand the converter will extend the
operating time before the batteries are depleted. The Converter
may also act as a secondary battery charging method during
periods of low air conditioning or heating demand. The
Converter is mounted in the cab, usually under the bunk. If the
Shore Power Converter is plugged in while TriPace and all
truck systems are off the converter will charge the truck
batteries.
If shore power is available, it should be connected when the
batteries are near full charge to receive the full extended run
time benefit of the shore power converter.

Unit Description
Power Inverter (Option)
The optional 1000 watt Pure Sine Wave Power Inverter
provides 115 Vac "Hotel Power" for the driver. It changes the
low voltage DC available from the truck batteries to high
voltage AC. The Inverter is mounted in the cab, usually under
the bunk.
NOTE: Use of the Power Inverter will reduce the total time
the air conditioning system is able to operate.
Truck Integration
The TriPace APU system is integrated with the following
Truck systems.
Truck Batteries: The truck’s own batteries provide part of
the power for the TriPace system. Four 12 Vdc batteries must
be connected to provide basic 12 Vdc output. For optimum
system performance the truck battery pack should be upgraded
to a type recommended by Thermo King. These batteries have
been specifically designed for the TriPace system to maximize
battery life and support deep discharge cycles. Shorter system
runtime will be experienced without the battery upgrade.
Alternator: The truck’s alternator provides primary battery
charging for the system while the truck is driving. With some
applications or truck operation profiles, such as short drive
times or high system demand, increased battery charging
capacity may be required. To provide the additional charging
capacity the alternator and charging cables may need to be
upgraded to 270 amps.
Ignition Switch: When the truck ignition switch is in the ON
or RUN position a signal is sent to the TriPace Main Controller.
After a 3 minute "Pull ahead" time delay the TriPace
system will be turned off (disabled) and the system will
begin a shutdown sequence. When shutdown sequence is
complete the TriPace system does not draw power from the
batteries. The time delay prevents short cycling the TriPace
system during short duration engine operation.
If the truck engine is still running when the 3 minute timer
expires the battery charging process will begin. When the truck
ignition is turned off the TriPace system is defaulted off
(disabled) and must be turned on (enabled) by the driver.

Operation Notes
If theTriPace system is operating and the truck ignition is
turned on, the system will initiate a 3 minute "Pull Ahead"
timer. If the truck ignition is still on when the timer expires the
system will enter a shutdown sequence.
During Air Conditioning operation the compressor is limited to
five ON events per hour. This will prevent short cycling of the
system. The system will reset one hour after the first event.
Maximum climate control time is controlled by the total
available power reserve in the TriPace batteries. To achieve
maximum run time the operator should take steps to conserve
power reserve by reducing power consumption, especially
when outside temperature is high. Suggested steps include:
•
If system is cycled off, it will not restart until a shutdown
sequence is completed.
Keep window curtains closed to reduce radiant heat that
will increase cab temperature.
•
When changing between operating modes the new mode will
not initiate immediately. A 2 second delay will allow changing
back or to another selection to avoid momentary mode starts.
Close curtain between cab and sleeper overnight to reduce
air conditioning load.
•
Limit the on time and number of cab lights and accessories
to reduce battery power drain.
The TriPace System is OFF by default. When the truck ignition

Battery Charging While Truck Is
Running
Charging amperage is provided by the truck alternator. With
some applications or truck operation profiles, such as short
drive times or high system demand, increased battery charging
capacity may be required. To provide additional charging
capacity the alternator and charging cables may need to be
upgraded to 270 amps.
NOTE: While the truck is idling there may not be enough
amperage produced by the alternator to effectively charge the
batteries. Many alternators must be turning a minimum of
1,200 RPM before effective battery charging is available.
Charging Process
The TriPace Main Controller will begin adding one battery at a
time to the charging process if there is excess charging capacity
available from the alternator. Each SCM is capable of charging
one battery at up to 40 amps.
•
First, the Main Controller will put one of the SCMs in
Charge mode, charging the battery with the lowest state of
charge. If system voltage does not drop significantly, the
SCM will remain in Charge mode. If system voltage does
drop, the truck batteries are not sufficiently charged. The
SCM will return to Null mode for a time then retry. SCM
will continue trying to engage Charge mode until it is
successful.
•
Once the first SCM is in Charge mode for a time the Main
Controller will attempt to add the second SCM to the
charging process. It will perform the same process until it
has both SCMs charging one battery each. SCMs will
switch between their batteries until all batteries are fully
charged. Total battery charging time is expected to be 6 10 hours depending on depth of discharge, traffic, driving
profile and alternator size.
Battery charging occurs in progressive stages. This prevents an
extremely high charge rate. The process begins when the truck
engine is started. The Smart Charging Modules (SCMs) will be
put in Null mode. All TriPace batteries will be isolated. The
truck’s batteries will be charged first.

Unit Description
The Thermo King Power Converter/Battery Charger converts
120 volts nominal A.C. to 13.6 volts D.C. As a power supply,
its tightly controlled regulation allows the user to operate any
12 volt nominal D.C. load up to the converter’s rated output
current. As a battery charger, the converter will maintain the
battery, delivering its full-rated current when the battery
capacity falls sufficiently low. The voltage is set to deliver its
maximum current for the necessary period of time that
minimizes undue stress to the battery caused by heating of its
cells. This helps to ensure the longest possible life of the
battery. Over time, as the battery nears its full capacity, the
converter will float-charge the battery to prevent self-discharge
of its cells.
•
Reverse Battery Polarity Protection.
•
Brown-Out Input Protection.
•
Over-Current Protection - cycle by cycle peak limiting as
well as rated current limiting to maximize the life of the
converter.
•
Over-Temperature Protection. In addition, the
converter/charger is designed with a unique “proportional”
fan control circuit. Fan speed is directly proportional to the
converter’s internal ambient temperature. This enables the
fan to turn on and off very slowly, minimizing unwanted
fan-starting noise.
•
The power supply is protected against reverse polarity on
the DC output. If a battery or the unit is hooked up
incorrectly, the fuses will blow and can be easily replaced.
Always use the same size and style fuse that came with the
converter. To change the fuses, use a screwdriver to loosen
the screws and remove the fuses. Always replace the fuses
with the same type and rating.
Protection Features
The Thermo King Power Converter/Battery Charger is
designed with high quality components to help ensure years of
continuous use. The unit is protected by multiple protection
features for a long, trouble-free life.

Unit Operation
Turning the Inverter On and Off
Operating Several Loads at Once
The power switch on the inverter’s front panel turns the control
circuit in the Thermo King Pure Sine Inverter on and off.
If you are going to operate several loads from the Inverter, turn
them on separately after you have turned the inverter on.
To toggle the inverter on and off from its front panel:
This will ensure that the inverter does not have to deliver the
starting current for all the loads at once.
1.
Press the inverter’s power switch button (for half a
second) to turn On the inverter (from Off).
2.
Press the inverter’s power switch button (for one second)
to turn Off the inverter (from On).

inverter draws no current from the battery.
WARNING: Risk of electrical shock. The unit’s power switch
when turned off does not disconnect power from the Thermo
King Inverter.
Turning the Inverter Off Between
Charges
When the power switch is on but no power is being supplied to
a load, the inverter draws less than 800 mA from the battery.
This is a low current draw. It would take a week to discharge a
150 Ah battery at this current, so you don’t have to worry about
excessive drain on your battery if you leave the inverter
switched on for a few days.
If you are not planning to recharge your battery within a week
or so, switch the inverter off.

Inverter Loads
The Thermo King Pure Sine Inverter will operate many AC
loads within its power rating. However, some appliances and
equipment may be difficult to operate. Please see “Exceptional
Loads” below carefully.
USB Loads
Many USB-powered devices such as portable music (MP3)
players, mobile phones, and video game players can be
charged and powered safely via the standard USB port.
However, some devices such as portable GPS receivers and
certain cameras may not work and even cause damage if you
use the USB cable that came with the product. Be sure that the
device only accepts 5 volts and can be charged or powered
using other sources of power. See the device’s owner’s guide
under specifications for information.
draw is within the inverter’s limits. If a motor refuses to start,
observe the VOLTS indicator while you are trying to start the
motor. If the indicator drops below 11 volts while the Thermo
King Pure Sine Inverter is trying to start the motor, this may
explain why the motor won’t start. Make sure the length and
diameter of the battery cables are appropriate. Check that the
battery connections are good and that the battery is fully
charged. If the cables are sized correctly, the connections are
good, and the battery is charged, but the voltage still drops
below 11 volts, you may need to use a larger battery.
Battery Charging Frequency
When possible, recharge your batteries when they are about
50% discharged or earlier. This gives them a much longer life
cycle than recharging when they are almost completely
discharged.
Exceptional Loads
Some induction motors used in refrigerators, freezers, pumps,
and other motor operated equipment need high surge currents
to start. The Thermo King Pure Sine Inverter may not be able
to start some of these motors even though their rated current
