AEV Data Conversion
 Convert the EEProm into physical parameters of:
• Time (seconds)
• Current (amps)
• Voltage (volts)
 Analyze the data by calculating:
• Power (watts)
• Incremental Energy (joules)
• Total Energy (joules)
Time, Current, Voltage, & Power
 Time:
t = t E / 1000
 Current:

Pin = V ∗ I
s = 0.0124 * Marks
t = time (seconds)
tE = EEProm time (milliseconds)
I = current (amps)
IE = EEProm equivalent current
VR = Arduino reference voltage
V = Voltage (volts)
VE = EEProm equivalent voltage
Pin = Power in (watts)
V = Voltage (volts)
I = Current (amps)
Energy
 Remember that Energy is the area under the power versus
time curve.
 A rectangle approximation of the power and time will be used
to calculate the incremental and total energy.
 There are 3
approximation
methods:
Energy
 The midpoint method will be used to calculate the energy.
 The midpoint method uses the averaged power of 2
neighboring points and multiplied by the time increment:
P1in + P2in
∗ (t 2 − t1 )
E1 =
2
 Sum up the incremental energy for the total value used
throughout the operation
MATLAB Functions Review
 The aevDataRecorder creates an excel file.
 To import the data into MATLAB, you can use:
• The Matlab Import Tool
 Home tab>Import Data
 Select only numerical data
• xlsread(‘filename’)
Things to Remember
 Executive Summary for Lab 06
 Update Project Portfolio
 Study for Lab Proficiency Quiz (LPQ)
 Extra Credit Video (Due: Lab 07 (Part 1))
 Continue to work on PDR (Due: Lab 09B)
