The Battery Charger has been designed to provide reliable, quality charging for battery systems in
electric drive vehicles. It is a high efficiency wide input voltage charger, the charger can output 1800W at
AC90V~265V in a smaller size. Many creative technology help to realize up to 94% of efficiency, and the
internal temperature is still under 50℃. The following are some new features:
□ Intelligent control output voltage and current by microprocessor, 100% calibration before
delivery
□ ±1% voltage and current accuracy
□ Active PFC &high freqency:smallerAC input(universal Voltage)current less interference, and
Conform to European Commission Regulation no 278/2009 and Energy Star Version2.0
□ AC 90-265Vworldwide operation: need not any alternative switcher, worldwide safe operation.
□ Low power consumption (less than 1W) at idle mode and standby mode
□ Up to 94% of convertefficiency.
□ Programmable output voltage from 10Vto102V
□ Programmable output current from 1Ato 25A
□ TFTcolorLCDdisplay output Voltage, current, power and internal temperature ontime.
□ Over current, over voltage, over load, over temperature, and short circuit protection
□ Short-circuit protection on output, safer and more reliable.
□ 2 Intelligent cooling fans turned on and adjust speed upon the temperature automatically
□ ZVS/ZCS and Synchronous Rectification
assure the highest efficiency.
□ High power density: 652W/Kg
□ Start at no load or full load
□ Approved by CE
□ 24 months warranty
Application
□ Home application
□ Electric drive vehicles

Warning
1. For any lithium battery, such as LiPo, LiFePO4, Li-ion, LiTo and other Li battery, the PCM
(Protection Circuit Module), BMS, cell monitor, saver etc. must be built-in the battery pack,
because the charger don’t monitor each cell voltage, even the total battery voltage don’t be
over charged, the single cell voltage is possible be over charged, special for larger impedance
cell. So if no PCM or BMS protect each cell from over charged, it is very dangerous.
2. Before charge, the cell count must be setup correctly, it is very important. Cell count is not the
cell quantity in a battery pack, it means cell count of connection in series, even 5 cells
connected in parallel, the cell count is 1 NOT 5. Please according to your battery pack rated
voltage and the following table get the cell count.

SV 102 v1. 2
1. Connect SV102 to AC 110 / 220V outlet by the special heavy power cable, if use other brand
cable, please note the wire AWG must be AWG14 at least.
2. Connect battery to charger.
3. Connect Charger BMS SV24 to charger if possible.
4. 2 seconds later, the idle interface is displayed; the charger is ready to charge. Actual output voltage,
current and internal temperature is also displayed, but SV102 is at idle mode (no output) to save
power consumption.
5. Press knob shortly can choose Battery type; press again on Battery
type such as LiPo can enter into LiPo charge setup interface. Here,
you can setup cell count, charge current, charge terminal current,
and charge terminal voltage per cell, and then press knob for 3
seconds start charging.
6. Stop charging, the battery voltage will goes down because of self-
discharge, if need maintain battery voltage, please setup the
Restart Charge YES, the charger will continue to charge when
battery voltage goes down to 5% of total battery voltage.
If set up to YES, the charger display KEEP after charge finished.
If set up to NO, the charger display DONE after charge finished.

7. Setup the charger work at Auto mode,
Finish all charge settings, alternate Auto charge YES and press Knob
for 3 seconds, the charger will start to charge, and work at Auto
mode in future till disable it.
When the charger work at Auto mode, what you need to do is
connect the AC power and battery to the charger. The charger will
operate at last settings. On Auto interface, press Knob for 3
seconds alternate to Idle mode. More details please read the Auto
charge flow.
8. During charge, many charge information is displayed as below
Cell count, Battery Type, Charge status
Battery voltage
Charge current
Capacity charged
Charge time
Internal temperature
9. Similar with LiPo charge setup, you can setup LiIo, LiFe, LiTo, Pb battery and NiMH/NiCd.
10. At any time Press knob shortly stop charging. The charger will work at idle mode to save power
consumption. Generally you needn’t disconnect it from AC outlet, because it only consume under
1W power at idle mode.

Tips
□ All parameters will be remembered by the SV102 till next change.
□ Choose battery type, and press knob for 3 seconds start to charge at last setup, save
many operating time.
□ When you need charge one battery repeat, you can save Auto Charge mode, the charger will
charge automatically, you need not setup any parameters, at AUTO charge, press Knob
button shortly can stop charging at any time, and press it again start to charge. Or during
charge, disconnect battery stop charging, and connect it again, start to charge.
When need to charge new battery at different parameters, disconnect battery, at
AUTO interface, press Knob button for 3 seconds alternate idle interface, the charger will
work at intelligent operate mode, all parameters can setup in this mode.

ProgramSetup
1. In charger idle interface, press knob button for 2 seconds enter
into Program Setup menu.
2. LCD display the following information in sequence and you can
modify its value. When you want to alter a parameter value, press
the knob button make the value blink then modify the value by
rotate the button. The new value will be confirmed and saved by
pressing the button again. Press knob buttons alternate different
items, and press knob to quit the setup menu.
