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.
Truck Integration
The TriPac Envidia APU system is integrated with the following OEM Truck
systems.
OEM Battery Pack
The OEM truck batteries provide part of the power for the TriPac Envidia
system. For base level system performance, there must be four 12 Vdc
Group 31 batteries connected to provide 12 Vdc output. For optimum system
performance the truck battery pack should be upgraded to four AGM type
deep cycle batteries. These batteries have been specifically designed to
support deep discharge cycles. Shorter system runtime will be experienced
without the battery upgrade.
Alternator
The OEM truck alternator provides primary battery charging for the system
while the truck is driving. It should be upgraded to a minimum of 270 amps.
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 300 amps or above. Alternator
and harness upgrades must be approved by the truck OEM.
Ignition Switch
When the truck ignition switch is turned to the On or Run position a signal is
sent to the TriPac Envidia Base Controller. A three minute “Pull ahead” timer
is activated and the system will continue to operate. If the switch is still on
after three minutes the TriPac Envidia system will be turned off (disabled)
and the system will begin a shutdown sequence. Once the sequence is
complete, the system does not draw power from the batteries. The time
delay prevents short cycling the system during short duration engine
operation. If the truck engine continues to run, the battery charging process
will begin. When the truck ignition is turned off, the TriPac Envidia system is
defaulted off (disabled) and must be turned on (enabled) by the driver.
