Special features

High power, high current, high-performance power conversion circuit. The iCharger series uses

advanced Synchronous buck-boost DC/DC converter technology with an output conversion efficiency

that can reach over 90%. This not only saves power and reduces heat build up but also makes the

charger more compact and conveniently mobile.

Input power with 4mm bullet connectors butt-welded alligator clips and wide input voltage ranges from

4.5V to 38V. The output power can be adjusted to align with the available input power, thus preventting

input current overload and protecting the DC source.The iCharger series can be used with three types of

Lithium batteries - LiPo, Lilo, LiFe - and has a fully integrated cell balancer.

The fan will start automatically according to the internal temperature and charge/discharge power, and

protect the charger if overheated. When the internal temperature is over 55℃(131 oF), the output power

is automatically reduced by 25%. If the temperature exceeds 60℃(140 oF) the charge cycle is stopped.

Convenient set of 10 battery profile memories that can be saved and loaded by number.

2x16 backlit LCD screen that provides rich information including active mode, current, voltage, total

charge (mAh), charging time and temperature etc.

Various charging/discharging settings and cycles to meet a wide range of customer needs. For Lithium

batteries: balance charging, normal charging, fast charging, storage, discharging, ext-discharging,

charge/discharge cycling, and battery monitoring. For NiCd/NiMH batteries: charging-auto,

charging-manual, discharging, charge/discharge cycling and forming charge. For Pb batteries: charging

and discharging.

Up to 1000w unique regenerative discharge capability. Regenerative discharge takes most of the output

battery‘s energy and puts it back into the input battery, which is not the same with the traditional methods

of discharge to deplete that energy in the form of heat across a transistor. That is, when you discharge

your LiPo for storage, you will be re-charging your Lead Acid input battery. The amount of current and

voltage that your input battery can accept limit the total amount of power that you can achieve, or 1000W,

whichever is lower.

Unique Lithium battery expanding discharge program. When you connect the external capacity

resistance, you can use it as the maximum discharge power capacity—1200W (@40V/30A).

Unique Lithium battery Monitor program. When you use other equipment to charge or discharge a

Lithium pack, you can use the iCharger to monitor the per-cell voltages, battery temperature and

-4-

iCharger Synchronous Balance Charger/Discharger 3010B

process time. If any individual cell appears over-charged or over-discharged or the pack is too hot or the

process has gone on for too long, the iCharger will generate an alarm sound and the related information

will blink.

Electric motor test mode can be used to run-in electric motors, test motor parameters and performance,

check tolerances etc.

Foam-cut drive. In this mode, the charger acts as a convenient power supply for a hot wire foam cutter.

Battery interior resistance measurement. The iCharger can not only measure the internal resistance of

the battery pack, and also can measure the per-cell internal resistance (only available for lithium battery).

Perfect protection. The iCharger has protection for reversed polarity (input or output), low input voltage,

battery temperature, charging capacity and time overrun.

iCharger 3010B has a 16Mbit flash storage, which can log offline charge and discharge data in 36 hours.

Support upgrading the hardware program by USB port. The iCharger also support the ―logview‖

software and can display, plot and analyze the charge and discharge data by it. (See detail information

about logview in the following website: http://www.logview.info)

Parameter setup

Users should check the parameter settings and adjust the parameter values according to the specifications of

the pack to be charged or discharged.

Note: The screen diagram on the left shows the system‘s default setting.

User parameter setup initial display.

iCharger checks the cell count of Lithium batteries automatically at the

beginning of the charge or discharge process in order to detect and avoid

erroneous setting by the user. However, deeply discharged batteries can be

perceived incorrectly. To avoid this problem you can set an initial time during

which to charge the battery at a low current, usually 100mA. Normally 10

minutes is enough to detect the cell count correctly. For batteries of different

capacities, you should adjust the time delay. Note: If you set the time delay

too long for a low capacity battery then the charging process can be finished

within the time delay with an erroneous cell count, which may damage the

battery and could be dangerous.

Range: 1 –10 min. (1min, default)

For balance charging Lithium batteries. If the Bal. Speed is set to Fast, the

CV termination current will be higher, the charging time shorter and the

per-cell voltage lower. When set to Slow, the CV termination current will be

lower, the charging time longer and the per-cell voltage higher. The default

value of Normal is between the Fast and the Slow. If Bal. Trickle is ON, the

iCharger won‘t stop charging until the current falls to around 20mA.

Bal.Speed: Fast, Normal & Slow, (Normal, default).

Bal.Trickle: OFF & ON: (OFF, default)

For balance charging Li battery. There are three balance modes options: CV

phase, storage voltage and always. If the balance mode is set to CV phase,

when any cell‘s voltage reaches the set voltage for CV, it will enable the

balancer. When set to ―always‖, the balancer will be enabled from the

beginning of the charge process. When set to ―storage voltage‖, the

balancer will be enabled when any cell‘s voltage exceeds the default storage

voltage for the configured chemistry.

Balance mode: CV phase, storage voltage, always (CV phase, default)

When running a charge/discharge cycle program for a Lithium, NiMH or

NiCd battery the charger will stop for a while before continuing to the next

phase. This allows the pack to cool down.

Range: 1 –60 min. (10 min default)

You can turn post charge-completion trickle charging. On or Off for NiMH,

NiCd or Pb batteries.

Range: OFF, 10 –500mA. (OFF,default)

Usually, the NiMH battery voltage will drop a little right after reaching full

charge. This is known as -△V. You can alter the iCharger‘s delta-peak

detection sensitivity.

When NiMH&NiCd batteries are deeply discharged or left unused for a long

time, they will produce a false -△V which stops charging early. You can

disable -△V testing to avoid this problem.

Range: 0 –30min (0, default)

Battery upper temperature limit. The battery temperature can be monitored

with the attached temperature sensor. In order to protect the battery from

damage due to high temperatures the iCharger will stop charging or

discharging immediately if the temperature exceeds the cut-off setting.

Users can choose ℃or oF as the temperature unit

Range: 20 –80℃(68 –176 oF). oF = (9/5)×℃+32.

Voltage Range: 4.50 –32.00V (4.50V, default)

Current Range: 1.0A –50.0A(50.0A, default)

Note: Current limit is not very accurate, which may be 20% difference, max.

Charge/Discharge power limit. The maximum charge/discharge power of

iCharger can be adjusted in order to limit internal temperature and to

protect the input current from over-loading. When the limit is set to AUTO

the iCharger can adjust the output charging power according to the input

capability.

CHG: 50 –1000W and AUTO. DCHG: 5 –80W(60 W, default)

Note: The maximum charge power capacity is also limited by input current.

The maximum input current of 3010B is about 50A, and Wmax ≈Imax *

Vin * 90%. (For example, when the input voltage is 15V, the maximum

charge power capacity ≈50×15×90％＝675W).

When Regenerative discharge is set to ON, discharging by charger internal consumption turns to charging

power supply (current and voltage limit can be set), which is shown in the following graph.

Note:

1．When in Regenerative discharging, charger‘s power supply needs to be rechargeable. For example,

Pb battery can be used for input power supply, but switch power adapter cannot.

2．The setting of regenerative discharge‘s current and voltage limit should be suit for power supply. For

example, using 12V Pb battery as power supply, the regenerative current and voltage should not be more

than its max charging current and voltage, or it may cause danger.

3．Regenerative discharge max power is the same with charger‘s setting max charging power, not

discharging power. (Restricted by setting regenerative discharge current and voltage limit, and discharge

current limit.)

4．Regenerative current limit is not very accurate, which may be 20% difference, max.

5．If input power supply voltage is more than setting regenerative limit voltage, charger will not start

regenerative discharge and internal discharge instead.

iCharger Synchronous Balance Charger/Discharger 3010B

Lithium battery program

The iCharger provides a number of Lithium programs including Balance, Normal, Fast and Storage. Only the

Balance mode requires the balance lead connected. However, the other modes will provide additional

per-cell over-voltage protection if the balance lead is connected compared to running them without it, where

they can only utilize the total pack voltage.

Vout = cell_count x cell_storage_voltage

Cycle - charge

Optional

Icv = Icc/10 AND Vout = cell_count x cell_max_voltage

Cycle - discharge

Optional

Vout = cell_count x cell_discharge_voltage

Icc = configured charge current for the CC phase

Icv = charge current during the CV phase

cell_max_voltage = configured termination voltage for the selected chemistry (eg LiPo = 4.2V)

cell_storage_voltage = configured per-cell storage voltage for the selected chemistry

cell_discharge_voltage = configured per-cell storage voltage for the selected chemistry

Icv = charge current during the CV phase

Vloss = 0.2 * (1 + Icv/10A); when in balance charging, charging line loss will compensate voltage.

Any time the battery‘s balance lead is connected the charger will monitor and display the cell voltages.

The balancer is only active during a BALANCE charge (not during the CHARGE or FAST programs)

The balance speed setting (Slow, Normal, Fast) controls the end-of-charging current threshold.

The CHARGE and FAST modes are identical except for the charge-termination threshold which is 1/10

of the charge current setting for CHARGE and 1/5 of the charge current setting for FAST mode.

While the CHARGE and FAST modes do not include any balancing action it is still safer to have the

balance lead connected since then the charger will provide per-cell over-voltage protection as described

below.

In all kinds of charge cycle, if the balance lead is connected and if any cell exceeds the allowable per-cell

peak voltage for the configured chemistry, the charge current will be reduced to ensure the voltage does

not rise any further. This will slow the charging process and if the charge current falls to 1/10 of the

charge current setting this will result in the charge cycle stopping altogether. Note that this is not the

normal CC-to-CV transition which would usually occur when all cells approach the nominal peak voltage

for the configured chemistry, but is a safety measure to respond to unbalanced cells in any mode or at

any time during the charge process.

Note: When Li batteries are in balance charging, charger's max output voltage = (cell_count x

cell_max_voltage) + Vloss

When connecting the Li batteries with main output port and the balance port, the

charger will check cell count automatically, and forbid changing cell count setting

by user himself. This is useful for all Li batteries‘charging and discharging mode.

iCharger Synchronous Balance Charger/Discharger 3010B

Charging Lithium battery in BALANCE mode

This function is for balancing the voltage of Lithium-polymer battery cells while charging. In the balance mode

the battery balance lead must be connected to the balance port on the right side of the iCharger. The pinout

of the balance port is shown in the diagram below. Charging in this mode is different from the normal

CHARGE mode because the iCharger can monitor the voltage of individual cells and adjust the input current

fed into each cell to normalize the voltage (for example: LiPo battery within 4.2V).

voltage.

iCharger Synchronous Balance Charger/Discharger 3010B

Charging a Lithium battery in normal CHARGE mode

The iCharger first charges with constant current (CC) according to the user setting then constant voltage (CV)

when the charging voltage reaches the peak point. In the CV phase the current gradually falls. The iCharger

will terminate charging when the current falls below than 1/10 of the configured charge current.

Fast charging a Lithium battery

The iCharger first charges with constant current (CC) according to the user setting then constant voltage (CV)

when the charging voltage reaches the peak point. In the CV phase the current gradually falls. The iCharger

will terminate charging when the current falls below than 1/5 of the configured charge current. This will result

in slightly less than 100% charge but will complete sooner than the Normal charge mode.

The left side of the first line set the type of battery (LiPo, Lilo or LiFe). The

value on the left side of second line sets the charge current and the value

on the right side of second line sets the cell count and voltage of the battery

pack. After setting the current and voltage, press Start/Enter for more than

3 seconds to start the next process.

set by the user. Usually, the auto-detect number won‘t exceed the number

set by the user. You should make sure that the configured number and the

actual number for the battery are the same and then you can start charging

by pressing Start/Enter. If not, press Batt type/Stop to go back to the

previous screen and adjust the setting.
