Charging techniques

E) CC/CV charging method
- CC stands for “Constant Current” and CV for “Constant Voltage”. This combined
method is used for LiPo, Lixx amd Pb batteries.
- The unit charges with the adjusted, constant amperage until the batteries have
reached their designated voltage: 4,2V/cell (LiPo), 3,3-4,3V/cell (Lixx) and
2,35V/cell (Pb). From this point on the Overloader2 charges the batteries with
a constant voltage. This means, the amperage is permanently re-adjusted
(reduced), so that the voltage of the batteries stays constant. This continues until
the amperage drops lower than 1/10C (capacity of the battery divided by 10).
After this the process goes over to trickle charge, the battery is ready for use.
- PLEASE NOTE: it is absolutely important, that you adjust the switch-off
voltage for these types of battery exactly according to the instructions from the
battery manufacturer.
- PLEASE NOTE: Read and follow all instructions from the manufacturer
of your battery!
F) Metering the internal resistance while Discharging
- During discharge the Overloader2 can meter the internal resistance of the
battery in process.
- This procedure always takes place exactly 1 minutes after staring the discharge.
This method ensures constant and comparable results.
- The metered result is then displayed instead of the nominal battery capacity.
- The automatic charge mode is only available for NiCd and NiMH batteries
- In this mode the Overloader2 continuously meters the internal resistance of the
battery, re-calculates and re-adjusts all parameters accordingly for best charging
results.
- The charge starts with a low amperage of 0,3A.
- The Overloader2 recognizes automatically the number of cells and uses a
deltaPeak of 4mV/cell.
- Switch-off criteria: deltaPeak, the adjusted temperature or maximum capacity.
