addPulseData
Description
addPulseData(
adds the current pulse data myHppcTest,HPPCPulseData,Name=Value)HPPCPulseData to the
TestSummary table of the HPPCTest object,
myHppcTest. This function also specifies options using one or more
name-value arguments.
Examples
This example shows how to add the data of a current pulse to a hybrid
pulse power characterization (HPPC) test object, HPPCTest.
Open the DownloadBatteryData example and load the required HPPC
data obtained for a BAK 2.9 Ah battery cell at 25 °C. This data consists of a table with
three columns. The columns of the table refer to time, voltage, and current values,
respectively.
openExample("simscapebattery/DownloadBatteryDataExample") load("testDataBAKcells/hppcDataBAKcell25degC.mat")
Store the HPPC data inside an HPPCTest object by using the hppcTest function. You can use this object
to view the data, add or edit breakpoints, add or remove pulses, and include additional
information such as state of charge and capacity. The HPPC data is a table, so you must
also specify each column name by using the TimeVariable,
VoltageVariable, and CurrentVariable arguments.
These names must match the names of the columns in the hppcData
table.
hppcExp25degC = hppcTest(hppcData,... TimeVariable="time (s)",... VoltageVariable="voltage (V)",... CurrentVariable="current (A)");
Analyze the identified current pulses of the hppcExp object by
using the TestSummary property. This property contains a summary of
the HPPC test that shows all the identified pulses and related data, returned as a
table.

Load the HPPC data obtained for a BAK 2.9 Ah battery cell at 0 °C and store the data
inside another HPPCTest object.
load("testDataBAKcells/hppcDataBAKcell0degC.mat") hppcExp0degC = hppcTest(hppcData,TimeVariable="time (s)",... VoltageVariable="voltage (V)",... CurrentVariable="current (A)",Temperature=zeros(numel(hppcData(:,1)),1));
Retrieve a single pulse from the hppcExp0degC object.
singlePulse = hppcExp0degC.TestSummary.HPPCData{17}Add this pulse data to the hppcExp25degC object by using the
addPulseData function and analyze the
TestSummary property table. Observe how the table now contains an
additional pulse.
