1. POWER INTERRUPTION (CURRENT INTERRUPTION) MODE:
For Battery and Fuel Cell Testing, a common method used to measure the internal impedance is the
Current/Power Interrupt or just the Interrupt method. The battery or fuel cell is loaded at a constant current,
and the current is interrupted by bringing it down to zero or lower current level. During the interrupt period,
the battery or fuel cell voltage is measured. As a result, the magnitude of the impedance can be determined.
The Interrupt method can be achieved in either CC mode or CP mode, with recommendations in the CC mode.
Local Control:
Press SINGLE twice
➔
FLASHING
→
Set the eLoad in CC or CP Mode
→
Set the Main Level to 0Adc or the desired current level via the encoder
→
Set the Peak Level to a current level larger than the Main to load the DUT
Note: Peak Level is set via the PEAK hot key and the encoder for value edit
→
Set the Power Interruption Pulse Width (PINT: 200 μs ~ 25000 μs)
→
Set the System Bandwidth (OSC3, OSC2, OSC1 and DEFAULT)
→
