Boost Charger
Boost Charger
Protect liftgate operation from under-charged batteries and effortlessly extend runtime.
Boost
Charger
FEATURES
• Dynamically adjusts charging current according to resistance
caused by the tractor-trailer connector (7-pin, 2-way or 1-way)
and compensates for electrical loads (lights, brakes, etc.) to
maximize battery charge
• Selector switch on the unit ensures optimal charge profile for
AGM or flooded lead acid batteries.
- Three stage battery charging (Bulk, Absorption and Float)
maximizes battery life, which allows for a reduction in longterm maintenance costs
• Temperature sensor (included) is mounted directly on the
battery post, enabling the unit to compensate the charge
voltage to optimize battery recharge levels and life of the
battery
• Fully sealed unit is IP67 and IP69K rated so it can be mounted
in locations subject to roadsplash.
APPLICATIONS
3 20 Amp model suited for 7-way
charging
3 35 Amp model suited for high
power stinger cable charging
(single or dual pole)
3 Supplemental EON PowerPack
charging from the 7-way
3 Refrigerated truck battery

Provides for electrically isolated
reefer start battery when needed
but allows for full truck battery
charging from reefer

- Order separately based on
application need
• Does not interfere with trailer ABS systems and prevents the
supply voltage from dropping below the minimum input voltage
of 9.5 Vdc, complying with FMVSS 121, SAE J2247, and TMC
RP141 (for air brake systems)
EXTEND MODE
• Lowers the low voltage cutoff from 12.7V to 12.5V DC
- At 12.5V, the low voltage cutoff activates to retain enough
battery energy to enable tractor starting capability, even in
cold weather
• The time that the unit will stay in extend mode is dependent on
the battery state of charge of the tractor and the load on the
charger
BRAKE INTERRUPT
• Uses an active voltage input monitor to adjust the output
charging current as to not drop Aux pin voltage lower than the
SAE spec
• Accommodates existing wiring issues and defects that might
exist with seven way plugs and cables that might lower the
voltage at the aux pin that a switched type of charger could not
detect

Notes :

IP67
Thermo King can be mounted anywhere on battery box. Internal is
preferred, but it can be mounted externally and exposed to direct tire
road spray and high pressure wash. Competition must be mounted
internal to battery box without exception.

Both systems use battery temperature compensation to adjust charging
voltage levels.
Using active voltage monitoring is a big advantage over using the brake

light circuit. Voltage monitoring allows the system to compensate for
switch cutoff circuit other voltage drops caused by corrosion or poor connections, thereby
greatly increasing system reliability and operation.
Not user selectable
Thermo King allows for user selecting of extend mode. When off, the
system will terminate the connection with the main batteries at 12.7V.
When on, extend mode will allow the level to drop to 12.5V, thereby
allowing the auxiliary battery pack to operate longer without the tractor
running. The competition uses a fixed 25 minute timer which can be
detrimental in single-battery systems when connected to the reefer as
the main battery. This can greatly decrease reefer battery life.
Not user selectable
Thermo King tailors the charging voltage profile to the battery type
given the high current charging to optimize battery life. The competition
only provides a fixed profile, regardless of battery type, which can be
very detrimental to both battery types since it is not tailored to either.

Thermo King units have superior corrosion protection along with
completely sealed water ingression protection. Competition model
easily corrodes ,which is why it must be placed inside a box. Warranty is
conditional on no corrosion.

Thermo King‘s warranty is unconditional 2 years and covered by an
extensive dealer network for certified installation and warranty coverage.
Competition is 1 year with conditions based on no corrosion or water
ingression.
