Information about Battery Discharger

The BDX battery discharger/analyzers have been designed to test the efficiency of batteries of any type, voltage and capacity.

These instruments perform a controlled discharge of the battery, while the current is kept constant by a high frequency DC/DC converter, based on MOSFET technology for smaller units and IGBT technology for bigger units.

The operation of the BDX is completely automatic: it's sufficient to connect the battery, to set the stop voltage, the maximum time and the discharge current. All the test is made automatically, while the digital display shows the partial results of battery discharger.

SEQUENCE OF OPERATION OF BATTERY DISCHARGER

1. Make sure the PC is NOT connected to the battery discharger BDX serial port;

2. Connect the battery to be tested;

3. Turn on the battery discharger BDX, by moving the general switch 0-1 to position “1”;

4. The display will show the BATTERY VOLTAGE for 3 seconds, then it will show the proposed STOP VOLTAGE, with the flashing ...
... letter “U”;

5. If needed, adjust the STOP VOLTAGE with the buttons + and -, and press the button SET to proceed;

6. The display will show the MAXIMUM TIME ALLOWED FOR TEST, with the flashing letter“h”;

7. If needed, adjust the MAXIMUM TIME ALLOWED FOR TEST with the buttons + and -, and press the button SET to proceed;

8. The battery discharger BDX is now ready to start the test. The display will show the message “rdy”.

9. Press both buttons + and – TOGETHER to start the test.

• If the potentiometer 0-100% is in position ZERO, the battery discharger BDX will start the test and the display will show the discharge current in AMPS. At this point, use the two potentiometers 0-100% and +/-5% to adjust the discharge current to the desired value.

• If the potentiometer 0-100% is not in position ZERO (all left), the battery discharger BDX will not start and the display will show the message “POT”. It's necessary to rotate the potentiometer 0- 100% left to the position ZERO, then the battery discharger BDX will start.
