Perceived by many in the industry
to be the “ultimate answer” for
marine electrical needs, Lithium
Ion batteries provide an astounding
capacity for rapid energy
deployment and equally effective
charging rates. But, as many
electrical technicians have found,
Lithium Ion batteries create their
own set of challenges.
As a new and somewhat untried
technol0gy, these powerful
batteries have yet to find any
standards for charging -- so profiles,
charging voltages, temperature
and safety limitations vary greatly
by manufacturer. In many cases,
there is still much disagreement
in regard to the exact profile these
batteries require to charge safely,
or efficiently.
There seems to be one constant,
though. These batteries require a
lot of charging current, and voltage
regulation that’s both responsive
and precise.
Balmar responded to numerous
requests by battery manufacturers,
designers and boatbuilders to
design a DC charging system that’s
capable of responding to the unique
needs of this emerging technology.
To meet these needs, we have
developed a new generation of
Max Charge voltage regulation
that targets the specific needs of
Lithium Ion batteries.
Unlike most commonly used battery
technologies, Lithium Ion batteries
will accept as much available
charging current as possible at
a fixed voltage value throughout
the entire time they are capable
of receiving a charge. (Imagine a
“bottomless” cup of coffee at your
local cafe.) At the end of the charge
period, many require the charger
to completely shut off.
The Max Charge regulator program
replicates that as closely as possible
by maintaining the proper charging
voltage until the regulator’s field
current drops below a given set
point, at which time the voltage
target is reduced to a lower voltage
level. By doing so, the alternator and
regulator can effectively operate
within the limitations of normal
engine operation while ensuring an
effective charge.
Balmar has bundled the Max Charge
regulator with the high-output
97EHD-12-265 alternator, a model
that’s well equipped to support the
heavy demands of marine Lithium
Ion battery banks. In addition, the
Lithium Ion Battery Charging
Package includes the MC-TS-A
Alternator Temperature Sensor
which ensures that the regulator
will automatically respond if the
extraordinary demands of these
new batteries cause the alternator
to exceed optimal operating
temperatures.
