Parameter Explanation
Name Explanation
Von Volt OPP test turn-on voltage
Von Delay Delay load time after the input voltage reaches the
turn-on voltage, range: 0.0
～
60.0 seconds
Orig Power OPP test initial load power
Rise Power Increment power value for each step
Delay
Running time per step, range: 0.01
～
3600.0 seconds
End Power Allowed maximum load power
End Volt Stop test if input voltage is lower than this figure
Max Trip Judgment upper limit for test power result
Min Trip Judgment lower limit for test power result
Note : If the input voltage is still higher than the end voltage after the end power is
reached, the test stops and the screen displays ERROR.
3.21. Battery Internal Resistance Test
The load uses the DC discharge method to measure the internal resistance of the battery.
According to Ohm's law R=U/I, the load causes the battery to pass two constant currents
in a short time, and the voltage difference between the two ends of the battery is
measured at the same time, and R=(U1-U2)/(I2-I1) is calculated to obtain the internal
resistance of the battery.
FT68200 uses a 4-wire system to measure the internal resistance of the battery. The user
not only needs to connect the input current cable, but also the remote voltage sense cable,
as shown in the figure below.
Figure 3-23 Battery Internal Resistance Test Wiring
The load provides a test result judgment function, which can compare the internal
resistance result with the specified upper and lower limits and report "PASS" or "FAIL".
