Every operating program in the unit is controlled with mutual links and
communications to prevent every possible error, so it introduces the maximum safety,
such as input voltage warning, reverse polarity protection and Lithium cell-count input
error warning. The entire firmware can be upgraded via USB from internet download at
our web page, when there needs to be changed.
- High-power and high-performance circuit
BC8HP employs the circuit that has maximum output power of 280Watts. As a result,
it can charge or discharge up to 27 cells of NiCd/NiMH and 8 series of Lithium batteries
with maximum current of 12A. Furthermore, the cooling system is so efficient that can
hold such a power without any trouble running the circuit or the operating program.

BC8HP can accept three types of Lithium batteries - LiIo, LiPo and LiFe. They have
different characteristics by their chemistry. You can select any one of them that you are
going to process before the job. For their specifications, refer 'Warnings and safety
notes' section.
- Lithium battery 'Fast' and 'Storage' mode
You can charge Lithium battery for special purposes. 'Fast' charge reduces the
charging time of Lithium battery and 'Storage' mode controls the final voltage of the
battery to be suit for long time storage.
- Maximum safety
Delta-peak sensitivity : The automatic charge termination program works on the
principle of the Delta-peak voltage detection. (NiCd/NiMH)
Auto-charge current limit : When charging NiCd or NiMH at 'AUTO' current mode, you
can set the upper limit of charge current to avoid from feeding high current to the
battery. This is very useful when charging the low impedance and small capacity NiMH
battery in 'AUTO' mode.
Capacity limit : The charging capacity always calculated by multiple of the charging
current and time. If the charging capacity exceeds the limit the process will be
terminated automatically when you set the maximum value.
-2-
Temperature limit(*) : The temperature of the battery on charging will rise by its
internal chemical reaction. If you set the limit of temperature the process will be expired
forcibly when the limit has been reached.
Processing time limit : You can also restrain the maximum processing time to prevent
from any possible defect.
Input power monitor : To protect the car battery using as input power from being
damaged, its voltage always being monitored. If it drops below the lower limit the
process will be ended automatically.
- Data store/load
For users convenience, it can store maximum 10 data of different batteries. You can
establish the data contains program setting of the battery to charge or discharge.
These data can be called back at any time you need and the process can be executed
without program setting.
- PC based analysis using USB communication(**)
For technical expert, BC8HP offers PC based program can analysis the
characteristic of the battery by USB port. It shows a graph of voltage, current, capacity
and temperature curves. It also shows the individual voltage of each cell in the Lithium
battery pack.

BC8HP recognizes the cell count of Lithium battery
automatically at the beginning of process to avoid from
erroneous setting by user. But deeply discharged battery
can be perceived incorrectly. To prevent the error, you
can set the time term to verify the cell count by the
processor. Normally, 10 minutes are enough to perceive
the cell count correctly. For the battery of larger capacity,
you may extend the time term. But if you set the time
term too long for the battery of smaller capacity, the
charge or discharge process can be finished within the
time term with the erroneous cell count. This may cause
the fatal result. If the processor recognizes the cell count
incorrectly at the beginning of charge or discharge
process, you may extend the time. Otherwise, you had
better use with the default value.
This shows the trigger voltage for automatic charge
termination of NiMH and NiCd battery. If the trigger
voltage is set higher, there is a danger of overcharging
the battery; if it is set lower, there is a possibility of
premature termination. Please refer the technical
specification of the battery.
(Disable, Delicate, Default, 5mV~20mV/cell)
Disable; The charger would not detect Delta-peak
voltage for termination. To terminate charging process,
the charger will check the parameters set up at other
safety parameters like max. capacity, safety timer or
safety temperature. If any one has been reached at its
limit, the charging process will be terminated. (for NiMH
only)
Delicate; The charger will detect a very small variation
at delta-peak voltage. Some NiMH batteries which
shows small voltage-drop at peak need to be use this
option.

Default; If you do not know much about this function, or
for ordinary batteries, select this mode. 12mV/cell for

An optional feature using temperature probe
contacting the surface of battery, the temperature
cut-off can be on or off. If it is on, set the maximum
temperature at which the charger should allow
battery to reach during charge. Once a battery
reaches this temperature during operation, the
process will be terminated to protect the battery.
The battery which is on the cyclic process of charge
and discharge can often become warm after charge or
discharge period. The program can insert a time delay
to occur after each charge and discharge process to
allow the battery adequate time to cool down before
being subjected to the next process. The value ranges
from 1 to 60 minutes.
You can set the trickle charge mode on or off. If it is
on, the charger will automatically supply the trickle
charge current to achieve the full charge without
overheating the battery after fast charge has been
terminated.

When you start a charge process, the integral safety
timer automatically starts running at the same time.
This is programmed to prevent overcharge the battery
if it proves to be faulty, or if the termination circuit
cannot detect the battery full. The value for the safety
timer should be generous enough to allow a full
charge of the battery.
This program sets the maximum charge capacity that
will be supplied to the battery during charge. If the
delta-peak voltage is not detected nor the safety timer
expired by any reason, this feature will automatically
stop the process at the selected capacity value.

'FAST' charging Lithium battery
The charging current is getting smaller as the process goes to the near end
term of Lithium battery charging. To finish charging process earlier, this
program eliminate certain term of CV process. Actually, the charging current
will goes to 1/5 from the initial value to end the process while the normal
charging goes to 1/10 at end of CV term. The charging capacity may be a bit
smaller than normal charging but the process time will be reduced.

The battery will be charged using the pulsed current
which is very brief and high-rate discharge pulses.
This will help to prevent from undesired side effect
like ‘memory effect’. When you select this mode, you
need to set the partial capacity which will be charged
with reflex mode. The charger will work with ‘Reflex’
mode only until the capacity has been charged, then
the charger will work at ‘Normal mode’.
- Set the charge current on the left and the partial
capacity on the right. The partial capacity should be
less than the total capacity of battery.
- Press and hold ‘ENTER/START’ button for more
than 3 seconds to start the process.

Pb (lead-sulphuric acid) battery program
This is programmed for charging and discharging Pb (lead-acid) battery of nominal
voltage from 2 to 36V. Pb batteries are totally different from NiCd or NiMH batteries.
They can only deliver relatively lower current compare to their capacity, and similar
restrictions definitely apply to charge. So the optimal charge current will be 1/10 of the
capacity. Pb batteries must not be charged rapidly. Always follow the instruction which
is supplied by the manufacturer of battery.

Glossary of terms
Amps(A): The unit of measure for charge or discharge electric current. The program of
the charger will show most of the current in amps(A) at its LCD screen.
Milli-amps(mA): The electric current, being amps(A) multiplied by 1000 and noted as
'mA'. So 2.0A is the same as 2000mA (2.0x1000). Or, to convert mA to amps, divide the
mA number by 1000. So 200mA is the same as 0.2A. If a current value is below 1.0A,
the LCD screen of the charger will still show the current in amps, not milli-amps. For
example, a current of 600mA will be displayed as 0.6A, and a current of 100mA will
actually be shown as 0.1A.
Capacity,milli-amp hours (mAh), and amp-hours (Ah): Charge energy stored by a
battery is called capacity, which is defined as how much current a battery can supply
constantly over one hour of time. Most hobby batteries are rated for capacity in 'mAh' or
milliamp hours. A 650mAh battery can deliver 650mA of current for one hour
(650mAx1hr = 650mAh). The batteries of very large capacity, such as lead-acid(Pb)
batteries, are usually rated in 'Ah' or amp-hours. A '12V 60Ah' car battery can deliver 60
amps of current for one hour (60Ax1hr = 60Ah).
Nominal voltage(V): The nominal voltage of the battery pack can be determined as
follows;
-.NiCd or NiMH: multiply the total number of cells in the pack by 1.2. A 8-cell pack will
have a nominal voltage of 9.6 volts (8x1.2).
-.LiPo: multiply the total number of cells in the pack by 3.7. A 3-cell LiPo wired in series
will have a nominal voltage of 11.1 volts (3x3.7).
-.LiIo: multiply the total number of cells in the pack by 3.6. A 2-cell LiIo wired in series
will have a nominal voltage of 7.2 volts (2x3.6).
-.LiFe: multiply the total number of cells in the pack by 3.3. A 4-cell LiIo wired in series
will have a nominal voltage of 13.2 volts (4x3.3).
If the nominal voltage of the battery is not printed on the battery's label, consult your
battery manufacturer or supplier. Do not guess the rated voltage of battery.
'C'-rating: Capacity is also referred to as the 'C' rating. Some battery suppliers
recommend charge and discharge currents based on the battery 'C' rating. A battery's
'1C' current is the same number as the battery's rated capacity number, but noted in mA
or amps. A 600mAh battery has a 1C current value of 600mA, and a 3C current value of
(3 x 600mA) 1800mA or 1.8A. The 1C current value for a 3200mAh battery would be
3200mA (3.2A).
