The extensive range of BCDC In-vehicle Dual Battery Chargers are designed and
manufactured in Australia for Australian conditions. Regardless of which charger you choose,
you’ll be assured of the high quality and reliability that comes with every REDARC product.
®
With more and more electrical devices being used when travelling
around Australia, along with more complex vehicle electrical systems,
having the right battery charging solution has never been more important.
The REDARC range of BCDC In-vehicle Dual Battery Chargers ensure
optimum performance of electrical equipment such as fridges, lights,
CPAP machines and even hydraulic pumps when they’re powered from
adual battery setup.
By employing a unique, multi-stage charging algorithm, BCDC In-vehicle
Dual Battery Chargers have been designed to charge any commonly-used
automotive auxiliary battery to 100% while you’re on the move and from
solar (if available).
Unique
charging profile
Most vehicle alternators are not designed
to fully charge an auxiliary battery. An
insufficient charge rate will, at best, shorten
the life and performance of the auxiliary battery
but may result in the battery being flat when
leastexpected.
Whether you need an auxiliary battery for leisure
or business, you need an auxiliary battery
charger you can really rely on. The REDARC
BCDC in-vehicle battery charger will ensure
your auxiliary battery will achieve and maintain
an optimal charge regardless of its type or size.
The charging algorithm has also been
independently verified and tested to ensure
battery life is maximised.
Charging algorithm
The BCDC In-vehicle Battery Charger range
features a three stage charging algorithm.
When the vehicle has started charging the main
battery and it reaches the required voltage level
the BCDC charger will commence charging
the auxiliary battery in boost, The boost stage
maintains a constant current until the battery
reaches its predetermined ‘absorption’ voltage.
The BCDC charger will then remain in the
absorption stage holding its set voltage until the
battery is 100% charged.
The BCDC charger then switches to the ‘float’
stage where it retains 100% charge until a
load on the auxiliary battery causes the battery
voltage to drop below a predetermined voltage
where it then re-enters the boost stage.
The advanced electronics in BCDC In-vehicle
Battery Chargers constantly monitor the
vehicle battery input charge to ensure that
your auxiliary battery always receives the ideal
voltage and current for maximum battery life
and performance. Additionally a highly advanced
battery isolator constantly monitors the vehicle
battery input charge level, protecting your start
battery from excessive discharge.
If it’s worth having an auxiliary battery, it’s
worth protecting it with a REDARC In-vehicle
BatteryCharger.
ECU-controlled variable
voltage alternators
A number of late model vehicles on the
market have ECU-controlled variable voltage
alternators to achieve better fuel economy
andincreasedperformance.
These systems vary the voltage from the
alternator based on driving conditions. When
the alternator voltage is low, the system voltage
can drop below 12.7 volts turning the standard
BCDC or isolator off.
In these instances we recommend using our
BCDC-IGN or BCDC-LV.
The next-generation BCDC1225D and
BCDC1240D can be used in 12 or 24 volt
vehicle systems with standard or variable
voltage/smart alternators, ensuring they will
deliver the best charge to your auxiliary battery.
Gauge value packs
If visual monitoring of a 12volt dual battery
setup is required, REDARC have a range of
BCDC In-vehicle Dual Battery Chargers, each
packaged with a G52-VVA dual voltage gauge.
