Applied DC Power Supplies and Electronic Loads
The following graph indicates the range of allowable charge voltage value / current value
calculated by the formula as specified below. Use the equipment that should not exceed the range
of the voltage value (starting discharge voltage value/end voltage value) and the current value
(constant current value). And the discharge voltage should not be applied below the discharge
minimum operating voltage.
When using the constant power discharge function (CP Dish), calculate the value of the discharging
current from the setting value of the constant power and the DUT (battery) voltage, and confirm its
value is within the range of the graph.
Discharge minimum operating voltage
*1
=
Minimum operating voltage of the Electronic load + the value of voltage drop caused by the route loss
p. 93
You can perform discharge tests with voltages that are lower than the discharge minimum
operating voltage by using a bias power supply.
*1. What is the discharge minimum operating voltage?
The discharge minimum operating voltage relies on the minimum operating voltage of the
Electronic load. Furthermore, the discharge minimum operating voltage shall be determined with
adding the value of route loss (the voltage drop).
See
When the Electronic load exceeds the allowable power or becomes under the lowest discharge
operating voltage while the discharge operation, the CD / B alarm is occured and abort the test.
