The graph below shows the range of dischargeable voltage and current using the following
equation. Use devices whose voltage (discharge start voltage, cutoff voltage) and current (constant
current) do not exceed the range. Also, make sure that the discharge voltage does not fall below
the minimum discharge operating voltage.
When using constant power discharge (CP Dish), calculate the discharge current from the specified
constant power value and DUT (battery) voltage, and check that it is within the range on the graph.
Minimum discharge operating voltage

= Minimum operating voltage of the electronic load +
voltage drop due to loss in cables
If you want to perform discharge tests with a voltage lower than the minimum discharge operating
voltage, use a bias power supply in combination.

What is minimum discharge operating voltage?
It is a voltage based on the minimum operating voltage of the electronic load. The minimum
discharge operating voltage is this minimum operating voltage with the loss in cable (voltage
drop) added.
See
If the allowable power of electronic loads is exceeded during discharging or the voltage falls below
the minimum discharge operating voltage, a CD / B alarm or the like occurs, and the test is
aborted.
