Table 6-2: Battery simulator parameters
Battery simulator parameters
Descriptions
The battery symbol represents the state of charge.
The light blue bar indicates the open circuit voltage
and the dark blue bar indicates the terminal voltage.
The differences between both bars show the voltage
drops on internal resistance.
Scale: the maximum of both bars are the maximum
defined voltage in the battery model and the mini-
mum is the minimal defined voltage.
SoC
State of charge represents the current battery
capacity, e.g. 85% SoC represents that 15% of bat-
tery capacity is used.
The open circuit voltage, Voc is the voltage between
the battery terminals with no load applied. The Voc
depends on the loaded battery model and the cur-
rent SoC.
The internal resistance, ESR (also known as Equiv-
alent Series Resistance) depends on the loaded
battery model and current SoC.
The terminal voltage, Vt is the voltage between the
battery terminals with applied voltage drop over the
ESR. Terminal voltage varies with charge or dis-
charge current.
Model
The loaded battery model applied in the battery sim-
ulator.
Battery capacity
The storage capacity for the battery:
●
Minimum value: 1
µ
Ah
●
Maximum value: 100 kAh
Editing a new value here overwrites the current
value loaded from the
Current limit
In addition to the resistance of the battery model,
current flow can be limited to protect possibly sensi-
tive equipment connected to the device.
There are three current limit settings available:
●
SoC < 0 % (the battery is empty)
●
SoC 0 % to 100 % (the battery is in normal
operation mode)
●
SoC > 100 % (the battery is fully loaded)
